Over the past 20 years, hospitals have also adopted and implemented data warehouse technology to facilitate the reuse of administrative and clinical data for research. However, the implementation of clinical data warehouses encounters a set of barriers: ethical, legislative, technical, human and organizational. This paper proposes an overview of difficulties and barriers encountered during a clinical data warehouse (CDW) development and implementation project. METHODS: We conducted a focus group at the 2023 Medical Informatics Europe Conference and invited professionals involved in the implementation of CDW. These experts described their CDW and the difficulties and barriers they encountered at each phase: (i) launching of the data warehouse project, (ii) implementing the data warehouse and (iii) using a data warehouse in routine operations. They were also asked to propose solutions they were able to implement to address the barriers previously reported. RESULTS: After synthesis and consensus, a total of 26 barriers were identified, 10 pertained to tasks, 5 to tools and technologies, 4 to persons, 4 to organization, and 3 to the external environment. To address these challenges, a set of 15 practical recommendations was offered, covering essential aspects such as governance, stakeholder engagement, interdisciplinary collaboration, and external expertise utilization. CONCLUSIONS: These recommendations serve as a valuable resource for healthcare institutions seeking to establish and optimize CDWs, offering a roadmap for leveraging clinical data for research, quality enhancement, and improved patient care.}, language = {eng}, journal = {Computer Methods and Programs in Biomedicine}, author = {Lamer, Antoine and Popoff, Benjamin and Delange, Boris and Doutreligne, Matthieu and Chazard, Emmanuel and Marcilly, Romaric and Priou, Sonia and Quindroit, Paul}, month = nov, year = {2024}, pmid = {39241462}, keywords = {Data Warehousing, Data reuse, Data warehouse, Electronic Health Records, Europe, Focus Groups, Guidelines, Health data, Humans, Medical Informatics, Recommendations}, pages = {108404}, }

They are only studied in high level maternities, small cohorts, all stages of perineal tear or in low-income countries. The aim of our study was to describe complications after primary OASI repair following a vaginal delivery in all French maternity wards at short and midterm and to assess factors associated with complication occurrence. METHODS: We conducted a historical cohort study using the French nationwide claim database (PMSI) from January 2013 to December 2021. All women who sustained an OASI repair following a vaginal delivery were included and virtually followed-up for 2 years. Then, we searched for OASIS complications. Finally, we evaluated factors associated with OASIS complication repaired or not and OASIS complication repairs. RESULTS: Among the 61,833 included women, 2015 (2.8\%) had an OASI complication and 842 (1.16\%) underwent an OASI complication repair. Women were mainly primiparous (71.6\%) and 44.3\% underwent an instrumental delivery. During a follow-up of 2 years, 0.6\% (n = 463), 0.3\% (n = 240), 0.2\% (n = 176), 0.1\% (n = 84), 0.06\% (n = 43) and 0.01\% (n = 5) of patients underwent second surgery for a perineal repair, a fistula repair, a sphincteroplasty, a perineal infection, a colostomy and a sacral nervous anal stimulation, respectively. Only one case of artificial anal sphincter was noticed. Instrumental deliveries (OR = 1.56 CI95\%[1.29;1.9]), private for-profit hospitals (OR = 1.42 [1.11;1.82], reference group "public hospital"), obesity (OR = 1.36 [1;1.84]), stage IV OASIS (OR = 2.98 [2.4;3.72]), perineal wound breakdown (OR = 2.8 [1.4;5.48]), ages between 25 and 29 years old (OR = 1.59 [1.17;2.18], refence group "age between 13 and 24 years old") and 30 and 34 years old (OR = 1.57 [1.14; 2.16], refence group "age between 13 and 24 years old") were factors associated with OASIS complication repairs. CONCLUSIONS: Maternal age, stage IV OASIS, obesity, instrumental deliveries and private for-profit hospitals seemed to predict OASIS complications.

However, as data are distributed across multiple software, it becomes challenging to cross-reference information between sources due to differences in formats, vocabularies, and technologies and the absence of common identifiers among software. To address these challenges, hospitals have adopted data warehouses to consolidate and standardize these data for research. Additionally, as a complement or alternative, data lakes store both source data and metadata in a detailed and unprocessed format, empowering exploration, manipulation, and adaptation of the data to meet specific analytical needs. Subsequently, datamarts are used to further refine data into usable information tailored to specific research questions.

Studies worldwide observed increased usage of antidepressants, anxiolytics, and hypnotics during the pandemic, notably among young people and women. However, few studies tracked consumption post-2021. Our study aimed to fill this gap by investigating whether the surge in the number psychotropic drug consumers in France persisted 2 years after the first lockdown, particularly focusing on age and gender differences. METHODS: We conducted a national retrospective observational study based on the French national insurance database. We retrieved all prescriptions of anxiolytics, hypnotics, and antidepressants dispensed in pharmacies in France for the period 2015-2022. We performed interrupted time series analyses based on Poisson models for five age classes (12-18; 19-25; 26-50; 51-75; 76 and more) to assess the trend before lockdown, the gap induced and the change in trend after. RESULTS: In the overall population, the number of consumers remained constant for antidepressants while it decreased for anxiolytics and hypnotics. Despite this global trend, a long-term increase was observed in the 12-18 and 19-25 groups for the three drug classes. Moreover, for these age classes, the increases were more pronounced for women than men, except for hypnotics where the trends were similar. CONCLUSIONS: The number of people using antidepressants continues to increase more than 2 years after the first lockdown, showing a prolonged effect on mental health.

Plusieurs outils existent pour optimiser l’analyse pharmaceutique des prescriptions ainsi que le nombre d’interventions pharmaceutiques (IP). Avec l’augmentation du nombre de données issues des séjours hospitaliers, ils pourraient bénéficier d’une approche fondée sur l’aide à la décision, mais en réalité peu sont intégrés dans les SADP. Objectifs L’objectif de ce travail est d’évaluer l’intégration d’un score dans un SADP afin de déterminer un seuil qui permettrait de distinguer les séjours hospitaliers bénéficiant d’une analyse pharmaceutique pouvant être à l’origine d’IP des séjours hospitaliers moins à risque de conduire à une ou plusieurs IP. Méthode Il s’agit d’une étude rétrospective et observationnelle, menée du 2 mars au 16 avril 2022. Le score qui a été intégré dans le SADP PharmaClass® (Keenturtle) est inspiré d’un score canadien. Les critères du score se composent de l’âge, du nombre de médicaments et du type de médicaments présents dans la prescription. Pour chaque hospitalisation, un score a été calculé au début du séjour et nous avons regardé rétrospectivement si un pharmacien avait fait une analyse pharmaceutique et si cette analyse avait abouti à une ou plusieurs IP. Une analyse statistique (courbe ROC et indice de Youden) a ensuite été menée pour déterminer le seuil de score optimal distinguant les séjours hospitaliers avec analyse pharmaceutique susceptible de conduire à une IP des séjours avec analyse pharmaceutique moins probable de conduire à une IP. Résultats Pendant la période de l’étude, 1717 séjours ont bénéficié d’un calcul de score, dont 973 (56,7 \%) séjours, une analyse pharmaceutique a été effectuée. Suite aux analyses statistiques, un seuil de 4 a été considéré comme discriminant pour identifier les séjours analysés conduisant à une ou plusieurs IP. À ce seuil, 600 (61,7 \%) séjours hospitaliers sont détectés dont 33,3 \% ont conduit à une IP, et 5,0 \% des séjours totaux n’ont pas été détectés bien qu’ayant fait l’objet d’au moins une IP. Discussion - Conclusion Les résultats de cette étude montrent qu’un score intégré dans un SADP peut aider les pharmaciens à détecter les séjours hospitaliers susceptibles de conduire à une IP. Cependant, le seuil optimal est difficile à déterminer, car il faut contrebalancer les séjours qui seront bien détectés de ceux qui seront détectés à tort ou encore des séjours qui ne seront pas détectés, alors qu’ils auraient dû. En pratique, ce score pourrait être utilisé en premier lieu sans seuil pour optimiser l’organisation des analyses pharmaceutiques à entreprendre et ainsi maximiser la détection des prescriptions à risque.

Although generally considered safe, recent evidence has linked PPI use with an increased risk of kidney disease, stomach cancer, pneumonia, dementia, cardiovascular events and potential bone health problems. This systematic review examines the effects of PPIs on bone health, including osteoporosis and changes in phosphocalcic and magnesium metabolism, through a comprehensive analysis of the recent literature. The relationship between PPIs, bone mineral density and fracture risk, especially in populations with comorbidities, is complex and we propose a focus based on recent data. Studies of the effect of PPI use on bone mineral density have shown mixed results and require further investigation. Observational studies have indicated an increased risk of fractures, particularly vertebral fractures, associated with PPI use. Recent meta-analyses have confirmed an association between PPI use and hip fractures with a dose-dependent effect. More recently, PPIs have been associated with serious disturbances in phosphocalcic and magnesium metabolism that require careful management and discontinuation. Proton pump inhibitor-induced hypomagnesemia (PPIH) is a well-established phenomenon. In addition, hypocalcemia secondary to severe hypomagnesemia has been described. Despite growing evidence of PPI-related risks, further research is essential to better understand the complex mechanisms, as most data are from observational studies and do not establish a causal relationship.

Or, en Etablissement d'hébergement pour personnes âgées dépendantes (Ehpad), de nombreux résidents en ALD ont bien une déclaration administrative mais ne sont plus suivis par leur médecin traitant (notamment après un départ en retraite, si l'Ehpad est éloignée ou si le médecin choisit de ne pas y intervenir). Notre objectif était de déterminer le taux de résidents d'Ehpad ayant un suivi par un médecin traitant avec ou sans déclaration administrative, et le taux de résidents n'ayant pas de suivi par un médecin traitant avec ou sans déclaration administrative. Méthodes En mai 2023, nous avons réalisé une étude épidémiologique descriptive auprès des 215 résidents des quatre Ehpad rattachés au Centre hospitalier de Boulogne-sur-Mer. Le suivi par un médecin traitant était déterminé par les équipes infirmières. Les troubles neurocognitifs ont été déterminés dans le dossier médical. Résultats Nous avons recensé 154 femmes (71,6 \%), 61 hommes (28,4 \%), de 82,0±10,3 ans, dont 64 \% étaient atteints de troubles neurocognitifs. Parmi les 215 résidents, 130 (60 \%) avaient un suivi par un médecin traitant — 121 déclaré administrativement (56 \%) et 9 non déclaré (4 \%). Il y avait 85 résidents (40 \%) sans suivi par un médecin traitant — 70 ayant pourtant un médecin déclaré administrativement (33 \%) et 15 non déclaré (7 \%). Au total, sur 72 médecins généralistes déclarés, 30 assuraient un suivi (dont 3 exerçant entre 10 et 16 km).

En effet, des variations saisonnières ont déjà été montrées sur les hospitalisations pour catatonie. Cette étude se concentre sur l'impact des vacances scolaires sur les délivrances de trois classes de psychotropes. En comparaison, nous étudions les médicaments non psychiatriques par les délivrances des insulines et des inhibiteurs de la pompe à proton (IPP). Méthodes Les délivrances en pharmacie d'anxiolytiques, antidépresseurs, hypnotiques, insulines et IPP sont identifiés dans le Système national de données de santé par les codes ATC correspondants. Pour chaque classe, le nombre de patients ayant au moins une délivrance a été calculée par semaine de 2015 à 2019. Les périodes de « petites vacances » (PV) sont définies comme les semaines où au moins l'une des zones est en vacances, les vacances d’été (VE) correspondent aux semaines où les trois zones sont en vacances entre deux années scolaires. L'effet des vacances sur le nombre de patients ayant une délivrance en pharmacie est estimé par un modèle de poisson pour chaque classe d’âge et classe médicamenteuse avec un risque de 5\%. Résultats Une diminution des délivrances d'anxiolytiques est observée dans chaque sous-groupe pour tout type de vacances hormis pendant les PV chez les 19-25 ans où le nombre de patients augmente. Les délivrances d'antidépresseurs sont plus fréquentes durant les PV pour les 12-18, les 19-25 et les 50-75 ans ainsi que durant les VE chez les 12-18 ans. Les délivrances d'hypnotiques sont diminuées pour tout type de vacances à tout âge, d'autant plus lors des VE. Pour les insulines, les délivrances sont plus nombreuses lors de tout type de vacances quel que soit l’âge. Enfin, les consommations d'IPP sont plus importantes pour tout type de vacances chez les 12-18 et 26-50 ans.

Actuellement, les chercheurs sont confrontés à un défi colossal pour identifier rapidement des articles d'intérêt. En réponse à cette problématique, les moteurs de recherche offrent un tri par pertinence. Cependant, ces algorithmes s'appuient sur les mots du texte, or ces derniers perdent parfois leur signification lorsqu'ils sont isolés de leur contexte. Une alternative pourrait être l'exploration des réseaux de citations. Notre objectif était d’évaluer la performance de l'analyse de réseaux pour trouver des articles scientifiques d'intérêts en la comparant à la recherche via PubMed. Méthodes Nous avons développé un outil en ligne, BibliZap (app.biblizap.org), qui permet une fouille systématique des références s'appuyant sur une base de plus de 200 millions d'articles (lens.org). Pour le comparateur, nous avons récupéré les résultats renvoyés par PubMed avec le tri par pertinence activé de 70 requêtes issues de revues systématiques (RS). Nous avons également extrait les articles sélectionnés par les auteurs de ces RS, ceux-ci constituaient les articles à retrouver. Pour l'analyse de réseaux, deux requêtes différentes par RS étaient faites à BibliZap : un article puis trois articles tirés au hasard parmi les articles à retrouver de la RS. Résultats PubMed trouvait 67,4 \% des articles d'intérêts (20 \% atteint à 220 articles lus, 60 \% atteint à 2640 articles lus). Avec un article d'intérêt en requête, BibliZap trouvait 70,6 \% des articles d'intérêts (20 \% atteint à 51 articles lus, 60 \% atteint à 1747 articles lus). Avec trois articles d'intérêt en requête, BibliZap trouvait 87,1 \% des articles d'intérêt (20 \% atteint à 23 articles lus, 60 \% atteint à 377 articles lus). Pour 44 \% des cas où la requête PubMed n'atteignait pas 100 \% de sensibilité, BibliZap permettait de compléter la recherche d'articles pour atteindre une sensibilité de 100 \%. Conclusion La recherche d'articles scientifiques par analyse de réseaux semble prometteuses pour trouver rapidement des articles d'intérêts. Elle semble également pertinente dans le cadre des revues systématiques en complément des requêtes textuelles.

Pour maintenir un accès aux soins suffisant, le temps médical doit donc être préservé, notamment en diminuant la charge administrative qui pèse sur les médecins. En moyenne, les médecins généralistes estiment passer 1h30 à 2h par semaine sur des certificats médicaux injustifiés. En mars 2023, le Collège de médecine générale a diffusé le site certificats-absurdes.fr pour mettre en lumière cette situation. Afin de renforcer cette initiative, nous avons mené une initiative en collaboration avec plusieurs Conseils départementaux de l'Ordre des Médecins (CDOM) visant à faire des rappels ciblés et personnalisés de la loi en vigueur sur les certificats médicaux, sur demande de médecins généralistes attachés à ces CDOM participant. L'objectif de notre travail de recherche était de décrire le motif des certificats médicaux sur une période de 100 jours et d'identifier les principaux demandeurs de certificats abusifs. Méthodes Nous avons réalisé une étude descriptive multicentrique sur tous les courriers de réclamation concernant des certificats médicaux reçus par les CDOM du Nord, des Ardennes, de l'Ariège, du Bas-Rhin, du Calvados, de l'Eure, du Gard, du Morbihan et du Territoire de Belfort. Les CDOM ont reçu les signalements de médecins concernant des demandes jugées abusives. Lorsque les demandes étaient illégales ou injustifiées, nous avons rédigé un courrier qui a été signé et envoyé par les CDOM aux organismes demandeurs. Résultats Les Conseils ont reçu un total de 203 réclamations, en majorité du département du Nord (76,4 \%), adressées par 103 médecins (53 femmes et 50 hommes). Le plus grand nombre concernait le domaine des contrats (assurance et prévoyance) représentant 71 réclamations (35 \%). Le milieu scolaire et périscolaire suivait avec 61 demandes (30 \%). Sur l'ensemble des demandes de certificat, 164 (80,8 \%) se sont avérées injustifiées ou illégales, et ont fait l'objet d'un courrier suivi d'échanges. Avec certitude, nous éviterons ainsi 3000 demandes par an dans le Nord. Nous espérons éviter entre 5000 et 10 000 demandes au terme de la démarche.

Cependant, la mise en place de ces EDS rencontre un ensemble de barrière éthiques, législatives, techniques, humaines et organisationnelles. Ce travail présente un aperçu des difficultés et des obstacles rencontrés dans les projets d'EDS et propose un ensemble de recommandations pour ce type de projet. Méthodes Nous avons organisé un atelier lors de la conférence « Medical Informatics in Europe 2023 » et avons invité des experts de la mise en place des EDS. Ces experts ont décrit leur EDS et les difficultés et obstacles rencontrés à chaque étape : (i) le lancement du projet de l'EDS, (ii) la mise en place de l'EDS et (iii) l'utilisation de l'EDS en routine. Ces difficultés ont été classées selon le « framework Systems Engineering Initiative for Patient Safety 2.0 framework » (SEIPS 2.0). Les experts ont également été invités à proposer des solutions qu'ils ont pu mettre en place pour surmonter les obstacles précédemment signalés. Résultats Après synthèse et consensus, 26 obstacles ont été identifiés, dont 10 concernaient les tâches, 5 les outils et les technologies, 4 les personnes, 4 l'organisation et 3 l'environnement externe. Une attention particulière doit être accordée à cinq barrières qui sont présentes tout au long du projet. De plus, le financement initial semble également constituer un obstacle majeur, les EDS étant souvent créés sans ressources dédiées. Pour relever ces défis, un ensemble de 15 recommandations pratiques est proposé, couvrant des aspects essentiels tels que la gouvernance, l'implication des participants au projet, la collaboration interdisciplinaire et l'utilisation d'expertises externes à l’établissement.

Méthodes Nous avons extrait l'ensemble des actes infirmiers réalisés à domicile entre le 1er janvier 2022 et le 31 décembre 2022 pour des patients atteints d'ALD. Ces actes ont été catégorisées en fonction de leurs spécificités, telles que la réalisation d'actes médicaux infirmiers (AMI), d'actes infirmiers de soins (AIS) ou d'une démarche infirmiers (DI). Nous avons identifié les cinq ALD les plus fréquentes, et les actes infirmiers dont bénéficiaient ces patients. Résultats Un total de 15 821 917 patients a été identifié avec au moins une ALD en France en 2022. D'autre part, 17 098 901 patients ont bénéficié de soins infirmiers à domicile la même année. Parmi ceux-ci, 5 828 890 présentaient au moins une ALD (34,09 \%). Au sein de cette population, les hommes représentaient 47,18 \% des patients et l’âge médian (Q1;Q3) étaient de 71 [59 ; 80] ans. Les cinq ALD les plus fréquentes étaient le diabète (1 683 479 patients, 21,17 \%), les tumeurs malignes (1 465 674 patients, 18,42 \%), les insuffisances cardiaques sévères, troubles du rythme cardiaque sévères, maladies valvulaires cardiaques sévères, malformations cardiaques congénitales sévères (800 423 patients, 10,07 \%), les maladies coronariennes (731 817 patients, 9,20 \%), et les troubles psychiatriques (650 180 patients, 8,18 \%); 28,31 \% des patients présentaient plus d'une ALD.

Cette pratique semble concerner deux sous-populations types : des multipares et, plus récemment, de jeunes nullipares pour lesquelles l'acte s'inscrit dans une démarche militante. La littérature scientifique montre que cette deuxième sous-population est susceptible de regretter par la suite sa demande. Notre objectif est de décrire l’évolution de cette pratique, et d'objectiver le regret à travers l'incidence d'actes permettant l'accès potentiel à une fécondité secondaire par le biais de la fécondation in vitro (FIV) ou de l'anastomose tubo-tubaire. Méthodes Nous avons analysé la base nationale du PMSI de 2013 à 2022. Nous avons inclus les séjours de femmes de 18 à 60 ans avec acte de ligature des trompes. Nous avons ensuite recherché dans tous les établissements la réalisation d'actes d'anastomose tubo-tubaire ou d'actes en relation avec une FIV. Ces événements sont analysés en survie. Résultats Le nombre total d'actes réalisés annuellement décroît fortement, de 43 449 en 2013 à 18 634 en 2022 (-57,1 \%). L’âge moyen est de 39,9 ans (SD=4,4) mais décroît de 40,9 ans en 2013 à 38,2 ans en 2022 (p=0). Par exemple, de 2013 à 2022, le nombre de patientes de 18 à 24 ans augmente significativement, de 41 à 152 (0,09 \% à 0,82 \%, p=0), et le nombre de patientes de 25 à 29 ans également, de 327 à 759 (0,75 \% à 4,07 \%, p=0). Les réversions sont des FIV (81,0 \%) et des anastomoses tubo-tubaires (19,0 \%). L’âge de la patiente est un facteur majeur (p=0). Par exemple, chez les 18-24 ans, la proportion cumulée de réversion est 4,7 \% à 1 an, 6,5 \% à 2 ans et 7,3 \% à 3 ans (hazard ratio=125 [86,7 ; 181] par rapport aux 40 ans et plus). Chez les 25-29 ans, la proportion cumulée de réversion est de 3,0 \% à 1 an, 3,7 \% à 2 ans et 4,5 \% à 3 ans (hazard ratio=76,5 [60,7 ; 96,3]). Conclusion Bien que l'activité totale de contraception féminine définitive décroisse, la demande augmente chez les jeunes femmes. Les tranches d’âge correspondantes sont associées à une très forte proportion d'hospitalisation pour réversion.

Les recherches appliquées comme méthodologique devraient pouvoir accéder à des données de santé. En protégeant les citoyens, la législation française freine cependant ces recherches, et empêche l'application des principes FAIR. Notre objectif est de générer des jeux de données fictives très réalistes, permettant aux recherches appliquées d'obtenir les mêmes résultats que sur des données réelles, et aux recherches méthodologiques d'être compatibles avec les données de santé. Méthodes La SFR Technologies de santé et médicament a obtenu le financement du CPER Tec'Santé, dont la plateforme e-Santé est spécifiquement dédiée à la génération et la diffusion de bases de données de santé fictives mais très réalistes. Résultats Nous présenterons ici les méthodes actuellement développées pour générer de telles données, en prenant l'exemple d'un jeu de données intra-hospitalières (PMSI, médicament prescrits, résultats d'analyses de biologie médicale). Nous présenterons les méthodes et résultats préliminaires d'évaluation sur trois axes : - Qualité : un expert peut-il distinguer les données réelles des données simulées ? - Utilisabilité : les résultats d'analyse statistique obtenus sur données simulées sont-ils identiques à ceux sur données réelles ? - Sécurité ressentie : un « hacker » qui analyse les données simulées peut-il croire identifier des personnes réelles ? Conclusion La génération de jeux de données synthétiques, ou populations jumelles numériques, ou « twin datasets », devrait lever deux familles de verrous. Premièrement, elle pourrait permettre à des chercheurs du monde entier de mieux étudier les phénomènes de santé des Français (et pas seulement des USA), que ces chercheurs soient des professionnels désirant éprouver des concepts avant d'accéder aux données réelles, ou des étudiants. Deuxièmement, elle devrait permettre à des chercheurs méthodologistes de mieux comprendre les données de santé, et mettre au point des méthodes applicables aux données de santé, plus complexes que dans d'autres champs (importance des variables catégorielles, taille des terminologies, données manquantes, hétérogénéité, complexité, etc.).}, urldate = {2024-06-07}, journal = {Journal of Epidemiology and Population Health}, author = {Chazard, E. and Lenain, R. and Ficheur, G. and Beuscart, J-B.}, month = mar, year = {2024}, keywords = {Données synthétiques, Jumeaux numériques, Tigital twin}, pages = {202238}, }

Méthodes Trois « data scientists » et un médecin ont comparé leurs expériences afin de proposer un pipeline intégrant les composants essentiels ou optionnels afin de faciliter la réutilisation des données pour la recherche en santé. Résultats Le « data lake » est un premier élément possible du pipeline. Il stocke à la fois les données sources et les métadonnées dans un format brut et détaillé et permet l'exploration et la manipulation des données pour répondre à des besoins analytiques spécifiques. L'entrepôt de données se présente comme le composant le plus répandu, recevant les données brutes directement des logiciels ou du « data lake ». Il est alimenté par le processus ETL (« Extract-Transform-Load ») qui nettoie les données brutes, puis les intègre dans un modèle de données unique, indépendant des logiciels. L'entrepôt de données fonctionne comme un référentiel unifié, centralisé et normalisé de données historiques détaillées. Pour favoriser la collaboration entre les institutions, l'entrepôt de données peut adopter un modèle de données commun et standardiser la structure des données et les terminologies. À ce stade, les données sont encore stockées dans des tables multidimensionnelles avec un format orienté ligne. À la suite, les datamarts transforment les données complexes en informations exploitables adaptées à des questions spécifiques. Ce processus est souvent désigné sous le terme de « feature extraction ». Un dernier composant, le « feature store », est essentiel pour présenter les « features » au format colonne et limiter les requêtes à des sélections de colonnes et d'enregistrements afin de les simplifier.

Plusieurs études ont signalé une hausse de l'utilisation d'anxiolytiques, d'antidépresseurs et d'hypnotiques en France après la période de confinement. L'objectif de cette étude était d'explorer si les accroissements préalablement constatés dans la consommation de médicaments psychotropes ont persisté en 2022 en France. Méthodes Nous avons mené une étude rétrospective à partir du Système national des données de santé. Nous avons inclus les délivrances hebdomadaires de psychotropes du 1er janvier 2015 au 31 décembre 2022. Le nombre d'individus recevant au moins une boîte par semaine a été considéré comme une série temporelle. A partir d'une régression de Poisson, nous avons calculé la pente avant le confinement, l'impact du confinement, ainsi que la variation de pente après le confinement pour différentes tranches d'âge et par genre. Résultats Les patients âgés de 12 à 18 ans ont enregistré le changement de dynamique le plus important traduisant une augmentation à long terme de consommation d'antidépresseurs, d'anxiolytiques et d'hypnotiques. Ils sont suivis par les 19-25 ans pour les antidépresseurs et les anxiolytiques. Les femmes ont été davantage touchées que les hommes par l'augmentation du nombre de délivrances d'antidépresseurs et d'anxiolytiques dans ces deux classes d’âge.

La plupart des DM sont conçus par des ingénieurs biomédicaux dont le cursus contient peu de formation en sciences médicales. Notre objectif est de créer un référentiel de formation médicale pour les ingénieurs concevant les DM. Méthodes Dans le but d’établir une liste de dispositifs médicaux pertinents à traiter, nous avons analysé les montants de remboursement de la liste des produits et prestations (LPP) et de la liste des actes techniques d'imagerie de la classification commune des actes médicaux (CCAM) établies par la sécurité sociale. Nous avons obtenu une liste de 45 catégories de DM incluant 69 DM. Pour chaque DM, nous avons imaginé une démarche inductive basée sur le programme du 2éme cycle des études médicales et notre avis d'expert. Le raisonnement est le suivant : on part d'un dispositif médical. On identifie un groupe de pathologies pour lesquelles il est utilisé. Ensuite on définit les éléments de physiologie se rapportant aux pathologies citées. Pour finir, on développe les éléments anatomiques utiles aux notions de physiologie. Afin de rendre le référentiel accessible, nous avons choisi de le concevoir sous forme d'ontologie que nous avons implémentée à l'aide du logiciel Protégé. Résultats Nous avons construit une ontologie en langage OWL comprenant un total de 69 DM, 61 pathologies, 42 notions de physiologie et 61 éléments anatomiques.

Trois méthodes d'analyses statistiques ont été comparées : des analyses bivariées de comparaisons de moyennes ou de proportions, un modèle de régression logistique pas-à-pas descendant et un modèle de « Classification and Regression Tree » (CART). Résultats Ces travaux exploratoires ont permis de mettre en évidence des caractéristiques potentiellement associées à l'hyperkaliémie. Ainsi, 22 caractéristiques ont été mises en évidence par régression logistique. L'utilisation de CART a permis de calculer la probabilité d'apparition des évènements parmi les 15 000 séjours dont 1,49 \% présentent un évènement d'hyperkaliémie; ainsi que la possibilité de déterminer des règles de prévention des hyperkaliémies chez les patients remplissant certaines conditions, par exemple : si administration de médicaments de l'hyperkaliémie et de l'hyperphosphatémie et absence administration de l'angiotensine ii et hyponatrémie et durée de séjour supérieure ou égale à 1,5 jour alors la proportion d'hyperkaliémie est de 50,7 \% (parmi 69 cas). Conclusion Les modèles de CART permettent de définir des règles de détection des évènements indésirables à partir de réutilisation des données de santé qui pourrait être implémentées dans des logiciels d'aide à la décision. Cependant, ces travaux doivent être confirmés sur des données réelles.}, urldate = {2024-06-07}, journal = {Journal of Epidemiology and Population Health}, author = {Gérard, E. and Lenain, R. and Chazard, E.}, month = mar, year = {2024}, keywords = {Classification and regression tree, Clinical Decision Support System, Data-reuse}, pages = {202247}, }

L'objectif de cette étude est de fournir aux cliniciens un modèle prédictif simple du risque de TS et de suicide dans les 6 mois après une TS. Méthodes Une cohorte prospective de 972 sujets, a été incluse du 26 janvier 2010 au 28 février 2013, dans 23 services d'urgences en France, dans les sept jours suivant une TS. Nous avons réalisé une analyse par arbre de survie avec toutes les variables sociodémographiques et cliniques disponibles à l'inclusion (méthode de TS, diagnostic psychiatrique via quatre items du MINI et échelle d'intentionnalité suicidaire de Beck). Les résultats de l'arbre de décision ont ensuite été utilisés pour définir un algorithme prédictif simple pour les cliniciens. Résultats La cohorte était composée de 63,6 \% de femmes et la moyenne d'âge était de 38 ans. Les résultats de l'arbre de survie ont mis en évidence trois sous-groupes de patients présentant un risque accru de récidive de TS ou de décès par suicide dans les six mois après la TS : 1) les patients présentant un trouble de l'usage de l'alcool (TUA) et une TS antérieure avec une consommation aiguë d'alcool (rapport de risque [RR]=2,92 ; IC 95 \%, 2,08 à 4,10), 2) les patients sans TUA, ayant fait 1 ou 2 TS et souffrant de troubles anxieux (RR=0,98 ; IC 95 \%, 0,69 à 1,39), et 3) les patients sans TUA et ayant des antécédents de plus de 2 TS au cours des trois dernières années (RR=2,11 ; IC à 95 \%, 1,25 à 3,54).

Le thésaurus MeSH a été créé au milieu du XXe siècle dans le but de systématiser l'indexation et de faciliter la récupération des articles scientifiques. Malgré l'avènement des moteurs de recherche par termes libres, peu d'études ont remis en question la pertinence du thésaurus MeSH, et aucune ne l'a fait de manière systématique. L'objectif de notre étude était de mesurer l'apport du thésaurus MeSH dans les requêtes PubMed construites pour des revues systématiques (RS) de la littérature. Méthodes Nous avons sélectionné l'ensemble des RS publiées dans quatre journaux prestigieux entre 2012 et 2021 et pour lesquelles une requête PubMed a été fournie. Chaque requête originale (V1) a été transformée pour obtenir une version contenant uniquement des mots du texte (V2) et une version contenant uniquement des termes MeSH (V3). Les trois requêtes ont été comparées en termes de sensibilité et de valeur prédictive positive (VPP). Résultats Au total, 70 RS ont été incluses. Trois requêtes V1 (4,3 \%) ne contenaient que des termes MeSH, 8 (11,4 \%) ne contenaient que des mots du texte, et 59 (84,3 \%) contenaient à la fois des termes MeSH et des mots du texte. La suppression des termes MeSH a diminué la sensibilité médiane (50,0 \% pour V1 à 42,4 \% pour V2) et a augmenté la VPP médiane (1,3 \% pour V1 à 1,6 \% pour V2), elle n'a eu aucun effet sur le nombre d'articles pertinents récupérés pour 39 des 70 revues (56 \%). En revanche, la suppression des mots du texte a diminué la sensibilité médiane (50 \% pour V1 à 16,7 \% pour V3) et a diminué la VPP médiane (1,3 \% pour V1 à 1,0 \% pour V3). En d'autres termes, les requêtes contenant des termes MeSH et des mots du texte fournissaient en moyenne 4 articles pertinents supplémentaires par RS par rapport aux requêtes contenant uniquement des mots du texte, mais il fallait trier 769 articles supplémentaires. Conclusion Il apparaît que l'ajout de sensibilité par l'utilisation du thésaurus MeSH est relativement faible et cette augmentation entraîne une perte de VPP significative.

L'objectif de cette étude est de décrire les caractéristiques des patients atteints d'une ALD en 2022 en France. Méthodes Nous avons extrait du Système national des données de santé, les patients présentant au moins une journée d'une ALD en 2022. Nous avons décrit les ALDs les plus fréquentes et qui touchaient les patients les plus jeunes, les patients les plus âgés, le plus d'hommes, et le plus de femmes. Résultats En 2022, 15 821 917 patients étaient atteints d'une ALDs, parmi lesquels 4 759 952 patients (30,1 \%) étaient atteints de deux ALDs différentes ou plus. Les patients étaient pour 49,07 \% des hommes et avaient un âge médian (Q1; Q3) de 69 (55; 81) ans. Les trois ALDs les plus fréquentes étaient le diabète (N=4 200 754 patients, 20,3 \%), les tumeurs malignes (N=3 299 014, 15,9 \%), et les troubles psychiatriques (N=2 064 650, 10,0 \%). Les trois ALDs qui concernaient les patients les plus jeunes étaient la scoliose structurale évolutive, la mucoviscidose et les hémoglobinopathies avec des âges médians (Q1; Q3) de 23 (17; 58), 25 (15; 36) et 26 (13; 45) ans, respectivement.

The objective was to assess the association between presarcopenia and sarcopenia and a higher risk of MACCEs. METHODS: This study on the UK Biobank prospective cohort, used data collected between 2006 and 2021. Community-dwelling Caucasian participants aged 37 to 73 years were included if values for Handgrip Strength (HGS) and Skeletal Muscle Index (SMI) were available and if no history of MACCEs was reported. Exposure was assessed using the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) criteria. Muscle strength was measured using HGS, and muscle mass using the SMI. Presarcopenia was defined through the two definitions available in the literature, as low HGS with normal SMI and as normal HGS with low SMI, whereas sarcopenia was defined as low HGS with low SMI. The main outcome was to determine whether presarcopenia and/or sarcopenia were predictors of MACCEs (composite events). RESULTS: A total of 406,411 included participants (women: 55.7\%) were included. At baseline, there were 18,257 (4.7\%) presarcopenics-subgroup n°1 (low HGS only), 7940 (2.1\%) presarcopenics-subgroup n°2 (low SMI only), and 1124 (0.3\%) sarcopenics. Over a median follow-up of 12.1 years (IQR: [11.4; 12.8]), 28,300 participants (7.0\%) were diagnosed with at least one event. Compared to NonSarc, presarcopenic (subgroups n°1 and n°2) and sarcopenic status were significantly associated with a higher risk of MACCEs (respectively fully adjusted HRs: HR = 1.25 [95\% CI: 1.19; 1.31], HR = 1.33 [95\% CI: 1.23; 1.45] and HR = 1.62 [95\% CI: 1.34; 1.95]).

Les séries évaluant les résultats à long terme et le risque de complications sont rares. L’objectif principal était de décrire les résultats cliniques et radiographiques à long terme après iSK réalisée dans un contexte post-traumatique. Les objectifs secondaires étaient de relever les complications post-opératoires, les reprises chirurgicales et leurs facteurs de risque de survenue. Notre hypothèse était que bien que l’iSK apportait de bons résultats cliniques, il existait des facteurs de risque de complications à identifier. Patients et méthodes Cette étude rétrospective monocentrique incluait tous les patients pour lesquels une iSK était réalisée en contexte post traumatique de 2008 à 2018. La douleur, la satisfaction, les amplitudes articulaires et les mesures radiographiques pré et postopératoires étaient relevées. Toutes les complications étaient recherchées et décrites, ainsi que les reprises chirurgicales. Plusieurs variables étaient analysées pour identifier les facteurs de risque de reprise opératoire après iSK : âge, sexe, mécanisme traumatique initial, traitement orthopédique ou chirurgical initial et type de chirurgie, délai de reprise chirurgicale par iSK après le traumatisme initial. Résultats Trente-sept patients étaient inclus. Au recul médian de 9,5 ans (min 7,3–max 11,5), 22 patients (60 \%) avaient une EVA à 0. Les amplitudes articulaires étaient significativement améliorées pour l’ensemble des patients (p{\textless}0,001). Dix-sept (46 \%) patients présentaient une complication, dont 5 (13,4 \%) cas d’ossifications, 4 (10,8 \%) cas de gêne due au matériel et 4 (10,8 \%) instabilités douloureuses du moignon ulnaire proximal. Treize (35 \%) patients nécessitaient une reprise chirurgicale. Deux facteurs de reprise chirurgicale après iSK étaient retrouvés : un délai entre traitement initial et iSK inférieur à 7,2 mois et un âge inférieur à 53,5 ans ; la combinaison des deux facteurs ayant une sensibilité 97,5 et une spécificité de 56,7. Conclusion L’iSK en contexte post traumatique améliorait significativement les amplitudes articulaires et permettait un contrôle des douleurs à un long recul. Une reprise chirurgicale semblait plus fréquente chez les patients de moins de 53,5 ans et lorsque l’iSK était réalisée moins de 7,2 mois après le traumatisme initial.

Ne disposant ni d’un registre sur les ostéotomies ni sur les arthroplasties de genou l’accessibilité aux données épidémiologiques est difficile en France justifiant ce travail rétrospectif ayant pour objectifs : d’estimer la survie des PUC et des OTV sans reprise chirurgicale avec pose d’une prothèse totale de genou (PTG) ; d’établir des facteurs de risque de reprise chirurgicale pour chacun des groupes. Hypothèse La survie à moyen terme des OTV serait meilleure que celle des PUC chez les patients de moins de 70 ans. Matériels et méthodes À partir de la base nationale du PMSI, entre 2011 et 2020, tous les sujets âgés hospitalisés en France pour réalisation d’une OTV ou d’une PUC ont été inclus. Soit 108 007 patients dont 43 537 OTV (29 330 hommes, 14 207 femmes) âgés en moyenne de 49,7 ans (IC95 \%=49,6–49,8) et 64 470 PUC (31 181 hommes, 33 289 femmes) âgés en moyenne de 60,5 ans (IC95 \%=60,5–60,6). Résultats La survie sans reprise chirurgicale par PTG était de 75,8 \% (IC95 \%=75,2–76,4) pour les PUC et de 80,6 \% (IC95 \%=80,0–81,3) pour les OTV (p{\textless}0,00001). Concernant les PUC, les facteurs de risque de reprise étaient : une faible activité chirurgicale annuelle de l’institution où était effectué le geste (HR=1,50 ; IC95 \%=1,41–1,59) (moins de 17 PUC par an), une obésité (HR=1,25 ; IC95 \%=1,18–1,32), et un âge inférieur à 60 ans, avec une classe d’âge 50–59 ans plus à risque (HR=2,41 ; IC95 \%=1,83–3,16 chez les 50–59 ans). Concernant les OTV, les facteurs de risque de reprise étaient : une obésité (HR=1,42 ; IC95 \%=1,31–1,53), une polyarthrite rhumatoïde (HR=2,75 ; IC95 \%=1,37–5,51), une chondrocalcinose articulaire (HR=2,01 ; IC95 \%=1,18–3,39), et un âge supérieur à 60 ans (HR=8,81 ; IC95 \%=7,23–19,73 chez les 60–69 ans). Le sexe masculin était un facteur protecteur de reprise pour les deux interventions : HR=0,75 (IC95 \%=0,72–0,79) pour les PUC et HR=0,73 (IC95 \%=0,69–0,77) pour les OTV. On observait une augmentation du nombre annuel de PUC, correspondant à la tendance à l’augmentation du nombre annuel d’arthroplasties en France, et une diminution du nombre d’OTV au fil du temps jusqu’à 2019. Conclusion Les OTV étaient associées à une meilleure survie à moyen terme que le groupe PUC en France chez les moins de 70 ans. Pour autant, une diminution de leur indication est constatée au profit des PUC alors que leurs facteurs de risques d’échec restent différents, laissant à penser que cette chirurgie conservatrice doit garder sa place selon le stade arthrosique.

We therefore performed a retrospective study, with the aims of 1) estimating UKA and HTO survival without revision by total knee arthroplasty (TKA), and 2) assessing risk factors for revision according to treatment group. HYPOTHESIS: Medium-term survival is better with HTO than UKA in under-70 year-olds. MATERIALS AND METHOD: All elderly patients undergoing HTO or UKA in the French National Hospitals Database for the period 2011-2020 were included: i.e., 108,007 patients; 43,537 HTO (29,330 male, 14,207 female; mean age 49.7 years, 95\% CI 49.6-49.8) and 64,470 UKA (31,181 male, 33,289 female; mean age 60.5 years, 95\% CI 60.5-60.6).

In UKA, revision risk factors comprised: low annual center volume ({\textless}17 UKAs per year) (HR=1.50; 95\% CI=1.41-1.59), obesity (HR=1.25; 95\% CI=1.18-1.32), and age {\textless}60 years, with maximum risk for 50-59 years (HR=2.41; 95\% CI=1.83-3.16 in 50-59 year-olds). In HTO, revision risk factors comprised: obesity (HR=1.42; 95\% CI=1.31-1.53), rheumatoid arthritis (HR=2.75; 95\% CI=1.37-5.51), joint chondrocalcinosis (HR=2.01; 95\% CI=1.18-3.39), and age {\textgreater}60 years (HR=8.81; 95\% CI=7.23-19.73 in 60-69 year-olds). Maler gender was a protective factor against revision in both groups: UKA, HR= 0.75 (95\% CI=0.72-0.79); HTO, HR=0.73 (95\% CI=0.69-0.77). The number of UKAs increased over the years, matching the increase in arthroplasty in France, with a decrease in HTOs until 2019. CONCLUSION: HTO showed better medium-term survival than UKA in under-70 year-olds in France. Even so, indications decreased in favor of UKA, although the respective risk factors differ. These findings suggest that conservative surgery still has a role, depending on osteoarthritis stage.

The aim of our study was to determine the causes of death 1 year after a suicide attempt (SA) in the VigilanS program, mortality rates, and risk factors associated with any cause of death and suicide. Methods: A prospective cohort of 7,406 people who had attempted suicide between January 1, 2017, and December 31, 2018, was included in the study. The vital status of each participant was sought, and the cause of death was established through a phone call to their general practitioner or psychiatrist. Second, the relationship between sociodemographic and clinical factors and death by suicide within 1 year of an SA was assessed using a multivariable Cox model. Results: At 1 year, 125 (1.7\%) participants had died, 77 of whom died by suicide. Half of the deaths occurred within the first 4 months after an SA. Hanging (20.3\%; 24/125) and self-poisoning (19.5\%; 23/125) were the methods the most often used for suicide. We demonstrated that male sex (HR = 1.79 [1.13-2.82], P = .01) and being 45 years of age or older (between 45 and 64 years old, HR = 2.08 [1.21-3.56], P {\textless} .01; 65 years or older, HR = 5.36 [2.72-10.54], P {\textless} .01) were associated with a higher risk of death by suicide 1 year after an SA and that being younger than 25 years was associated with a lower risk (HR = 0.22 [0.07-0.76], P = .02). Conclusions: One out of 100 people who attempted suicide died by suicide within 1 year after an SA. Greater vigilance is required in the first months following an SA, especially for males older than 45 years.

The objective was to assess whether presarcopenia and sarcopenia are associated with an increase in fracture risk. We conducted a retrospective study using the UK Biobank cohort and the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) criteria. Muscle strength was evaluated using hand-grip strength (HGS) and muscle mass using the skeletal muscle index (SMI; from bioimpedance analysis). Presarcopenia was defined through the two definitions available in the literature, as low HGS with normal SMI and as normal HGS with low SMI, and sarcopenia as low HGS and low SMI. Fracture events were recorded as "fracture" (location compatible with an osteoporotic origin) and "major osteoporotic fracture" (MOF), as listed in the FRAX tool. Associations were assessed using Cox proportional hazards models, adjusted for sarcopenia and osteoporosis risk factors. Adjusted hazard ratios (HRa ) and their 95\% confidence intervals (CI) were reported. A total of 387,025 participants (women 54.4\%; median age 58.0 years; interquartile range [IQR] 51.0-63.0 years) were included. At baseline, there were 18,257 (4.7\%) presarcopenic participants-subgroup 1 (low HGS only), 7940 (2.1\%) presarcopenic participants-subgroup 2 (low SMI only), and 1124 (0.3\%) sarcopenic participants. Over a median follow-up of 12.0 years (IQR 11.4-12.6 years), 18,300 (4.7\%) participants were diagnosed with at least one incident fracture. Presarcopenic (subgroups 1 and 2) and sarcopenic status were significantly associated with a higher risk of fracture (respectively adjusted HRs: HR = 1.26 [1.19-1.33], HR = 1.20 [1.11-1.30], HR = 1.30 [1.08-1.56]) and with a higher risk of MOF (respectively adjusted HRs: HR = 1.30 [1.21-1.40], HR = 1.19 [1.08-1.72], HR = 1.18 [0.93-1.49]). In a middle-aged population, the fracture and MOF risks were higher in both presarcopenic and sarcopenic participants compared with nonsarcopenic participants. © 2023 The Authors.

Not covalently bound to PVC, DEHP can migrate into blood products during storage. Recognized as an endocrine disruptor and raising concerns about its potential carcinogenicity and reprotoxicity, DEHP is gradually being withdrawn from the medical device market. Therefore, the use of alternative plasticizers, such as diisononylcyclohexane-1,2-dicarboxylate (DINCH) and di(2-ethylhexyl) terephthalate (DEHT), as potential candidates for the replacement of DEHP in medical transfusion devices has been investigated. The purpose of this study was to evaluate the quantity of PVC-plasticizers in the blood components according to their preparation, storage conditions and in function of the plasticizer. MATERIALS AND METHODS: Whole blood was collected, and labile blood products (LBPs) were prepared by the buffy-coat method with a PVC blood bag plasticized either with DEHP, DINCH or DEHT. DINCH and DEHT equivalent concentrations were quantified in LBPs by liquid chromatography-tandem mass spectrometry or coupled with UV and compared to DEHP equivalent concentrations. RESULTS: The plasticizer equivalent concentration to which a patient is exposed during a transfusion depends on the preparation of LBPs as well as their storage conditions, that is, temperature and storage time. At day 1, for all LBPs, the migration of DEHP is 5.0 and 8.5 times greater than DINCH and DEHT, respectively. At the end of the 49 days storage period, the DEHP equivalent concentration in red blood cells concentrate is statistically higher when compared to DINCH and DEHT, with maximal values of 1.85, 1.13 and 0.86 μg/dm2 /mL, respectively. CONCLUSION: In addition to lower toxicity, transfused patients using PVC-DEHT or PVC-DINCH blood bags are less exposed to plasticizers than using PVC-DEHP bags with a ranging exposure reduction from 38.9\% to 87.3\%, due to lower leachability into blood components.}, language = {eng}, journal = {Vox Sanguinis}, author = {Thelliez, Aurélie and Sumian, Chryslain and Chazard, Emmanuel and Reichenberg, Stefan and Lecoeur, Marie and Decaudin, Bertrand}, month = may, year = {2023}, pmid = {37246454}, keywords = {2-dicarboxylate, di(2-ethylhexyl) phthalate, di(2-ethylhexyl) terephthalate, diisononylcyclohexane-1, diisononylcyclohexane-1,2-dicarboxylate, labile blood product, metabolites, plasticizer migration}, }

Les informations ne sont pas toujours directement disponibles dans la base de données source et doivent être calculées a posteriori. L'objectif principal de cette étude est de présenter une description standardisée des étapes et des transformations nécessaires lors du processus d'extraction de caractéristiques. Méthodes Cette étude a comporté les deux étapes suivantes: (1) la collecte de cas d'étude pertinents liés à l'extraction de caractéristiques; (2) la description normalisée des données brutes, des étapes et des transformations, qui étaient communes aux cas d'étude. Résultats Nous avons interrogé 10 chercheurs de trois hôpitaux universitaires français et de la Haute Autorité de santé, qui ont participé à huit études rétrospectives et observationnelles. Sur la base de ces études, deux états (piste et caractéristique) et deux transformations (la définition de pistes et l'agrégation de pistes) ont émergé. La "piste" est un signal ou une période d'intérêt dépendant du temps, défini par une unité statistique, une valeur et deux jalons (un événement de début et un événement de fin). La "caractéristique" est une information de haut niveau indépendante du temps, de dimension identique à l'unité statistique de l'étude, définie par un label et une valeur. La dimension temporelle est devenue implicite dans la valeur ou le nom de la variable. Discussion/Conclusion Nous proposons une description standardisée du processus d'extraction de caractéristiques. Ce processus combine les deux étapes de définition et d'agrégation des pistes. En divisant l'extraction de caractéristiques en ces deux étapes, la difficulté a été gérée lors de la définition des pistes. La standardisation des pistes nécessite une grande expertise au niveau des données, mais permet l'application d'un nombre infini de transformations complexes. Au contraire, l'agrégation des pistes est une opération très simple avec un nombre fini de possibilités. Une description complète de ces étapes pourrait améliorer la reproductibilité des études rétrospectives.

La perturbation de la composition du microbiote intestinal par des antibiotiques pourrait affecter l'efficacité des inhibiteurs de point de contrôle immunitaire. Dans une étude portant sur des patients traités par ipilimumab, nous avons cherché à évaluer la relation entre l'administration d'antibiotiques à l'hôpital et la survie globale. Méthodes Les patients ayant été traités par ipilimumab entre janvier 2012 et novembre 2014 ont été sélectionnés à partir de la base de données nationale française du Programme de médicalisation des systèmes d'information. L'exposition aux antibiotiques était définie comme la présence d'un séjour hospitalier avec une infection bactérienne systémique documentée dans les deux mois précédant ou le mois suivant l'initiation de la toute première cure d'ipilimumab du patient. Le critère de jugement principal était la survie globale. Résultats Nous avons étudié 43 124 séjours hospitaliers impliquant 1585 patients pris en charge dans 97 centres en France. Tous les patients avaient reçu une monothérapie par ipilimumab pour un mélanome avancé ; 117 des 1585 patients (7,4 \%) ont été exposés à une antibiothérapie systémique à l'hôpital pendant la période d'exposition définie. La survie globale médiane était plus courte chez les patients présentant une infection (6,3 mois, contre 15,4 mois chez les patients sans infection; hazard ratio (HR)=1,88, intervalle de confiance à 95\% [1,46; 2,43], p=10−6). Dans l'analyse multivariée, l'infection était toujours associée de manière significative à une diminution de la survie globale (HR=1,68, [1,30; 2,18], p=10−5).

Elle s'appuie sur une étape d'extraction de caractéristiques, qui simplifie les données avant l'analyse statistique. Quelles variables sont généralement utilisées ? Comment sont-elles transformées ? Nous analyserons des cohortes historiques traditionnelles (recherche sur des personnes). Méthodes Revue de la littérature: analyse de toutes les cohortes historiques publiées dans les quatre plus grands journaux généralistes en 2019 (pré-COVID), analyse des variables utilisées et de leurs transformations. Résultats Les journaux sont: JAMA, BMJ, Lancet et NEJM. Ils ont publié 22 cohortes historiques sur des personnes en 2019, impliquant 660 variables, dont 570 explicatives (86,4 \%) et 90 à expliquer (13,6 \%). Onze articles (50,0 \%) utilisent un modèle de Cox. Les variables rencontrées décrivent le sexe (86,4 \% des articles), l'âge (81,8 \%), d'autres informations démographiques (100 \%), des maladies chroniques (86,4 \%) ou aiguës (50,1 \%), des caractéristiques de l'hôpital (18,2 \%), d'autres informations liées au soin (72,7 \%), des résultats de biologie (36,4 \%), des médicaments (50 \%), le décès (63,6 \%). Nativement, elles sont binaires (62,6 \%), quantitatives (21,3 \%), qualitatives (12,6 \%), ou purement temporelles (2,6 \%). Les variables sont transformées pendant l'analyse. Les variables explicatives sont majoritairement temps-dépendantes (465 soit 70,5 \%), mais presque toutes considérées comme constantes lors de l'analyse (438 soit 94,1 \% d'entre elles). En outre, 65 des 660 variables (9,8 \%) changent de nature, principalement des variables quantitatives qui sont discrétisées (43 des 147 variables quantitatives, soit 29,3 \%). Discussion/Conclusion Ces résultats nous orientent pour concevoir un cadre méthodologique de réutilisation de données. Leçon 1: conserver le caractère quantitatif des variables explicatives n'est pas une priorité, ce qui s'explique par les hypothèses non-vérifiées (linéarité, log-linéarité) et le besoin de seuils de décision. Leçon 2: les chercheurs gèrent bien les variables à expliquer temps-dépendantes (survie), mais pas les variables explicatives temps-dépendantes. Il faut donc développer des méthodes simples d'extraction de caractéristiques permettant de préserver le temps. Rappelons que, au fond, presque toutes les variables sont temps-dépendantes.

Le suivi des réhospitalisations dans tous les établissements de France et tous les champs (MCO, HAD, SSR, Psychiatrie) permet d'étudier la survie des patients. Les chercheurs qui accèdent au SNDS peuvent, à l'aide des données de l'Assurance maladie et du CepiDC, identifier des décès supplémentaires hors PMSI. Les autres chercheurs, qui n'accèdent qu'au PMSI, se contentent généralement d'écrire que, à leur connaissance, la plupart des patients décèdent en établissement. Est-ce vrai ? Quelle est la proportion de décès hors du PMSI, en fonction des âges et des pathologies étudiées ? Notre objectif est de fournir aux chercheurs un outil simple pour estimer le nombre de décès qu'il leur manque. Méthodes Nous utilisons les données du CepiDC de 2017 (avant la pandémie), disponibles sur la plateforme du Système national des données de santé (SNDS). Nous préparons un calculateur permettant, en renseignant l'âge et la cause de décès (chapitre de la CIM10) de patients ou groupes de patients dont le décès a été observé dans le PMSI, d'estimer le nombre de décès hors du PMSI. Résultats L'outil est disponible gratuitement, sans inscription et sans traçage sur la page http://deceshorspmsi.chazard.org .La proportion de décès hors PMSI est globalement de 3,13\%. Elle varie notablement en fonction du motif de décès, allant de 0,0 \% pour "Grossesse, accouchement et puerpéralité" à 86,7 \% pour "Certaines affections dont l'origine se situe dans la période périnatale (...)". Elle varie également en fonction de l'âge, allant de 2,11 \% pour les décès entre 70 et 74 ans, à 57,8 \% pour les décès entre 0 et 4 ans.

Objectif: utiliser des données ouvertes de mortalité pour illustrer comment un calcul simpliste peut induire en erreur. Méthodes Nous utilisons les données 2016 du CepiDC en France métropolitaine, en séparant les cardiopathies ischémiques (CI) de toutes les autres causes. Pour tous les morts de l'année 2016, ces données fournissent le sexe, l'âge au décès, et la cause. Méthode 1 (morts réels): à la manière d'une étude rétrospective, nous calculons le sex ratio des morts par CI (en ignorant les autres causes), par classe d'âge. Méthode 2 (cohorte virtuelle): nous simulons des naissances une année donnée. Supposant que ces personnes mourraient au même âge que les morts de 2016, nous simulons leurs décès par CI ou pour d'autres causes, année après année. Pour chaque classe d'âge, nous calculons le risque relatif entre le sexe masculin et le décès par CI. Résultats Méthode 1: le sex ratio vaut successivement 2,36 (25-34 ans), 5,60 (35-44 ans), 4,85 (45-54 ans), 5,03 (55-64 ans), 3,76 (65-74 ans), 1,87 (75-84 ans), 0,90 (85-94 ans), 0,41 (95-104 ans), et 0,40 (après 105 ans). Méthode 2: le risque relatif vaut successivement 2,39 (25-34 ans), 5,69 (35-44 ans), 4,98 (45-54 ans), 5,32 (55-64 ans), 4,33 (65-74 ans), 2,52 (75-84 ans), 1,59 (85-94 ans), 1,31 (95-104 ans), et 1,29 (après 105 ans). Discussion/Conclusion La méthode 1 peut faire croire que les femmes meurent plus de CI que les hommes au-delà de 85 ans. Elle ne prend pas en compte les risques concurrents (ex: cancers), ni le fait que les hommes vivent moins longtemps (notamment à cause de la mortalité par CI). Elle reste une approximation acceptable de la méthode 2 en-dessous de 45 ans. La méthode 2 est plus fidèle à la réalité: à tout âge, les hommes meurent plus que les femmes de CI.

Les médecins interrogés préconisent en priorité de sensibiliser les patients, de ne plus accueillir les récidivistes (hors urgences), et de les sanctionner financièrement (cotation non-remboursable, déduite des remboursements ultérieurs). Discussion / conclusion Résoudre le problème des "lapins" serait aussi efficace que repousser de l'âge de la retraite de 2,4 ans ou supprimer 16,3 jours de congés chaque année, ou rajouter 1h43 de travail chaque semaine pour TOUS les médecins de France. Ce serait un levier très important sur l'offre de soins ambulatoire.

Series evaluating long-term outcomes and the risk of complications are rare. The main objective was to describe the long-term clinical and radiographic results after SKp performed in a post-traumatic context. The secondary objectives were to identify postoperative complications, surgical revisions, and their risk factors for occurrence. Our hypothesis was that although SKp confers good clinical results, identifiable risk factors for complications exist. PATIENTS AND METHODS: This monocentric retrospective study included all patients for whom an SKp was performed in a post-traumatic context from 2008 to 2018. Pain, satisfaction, range of motion and pre- and postoperative radiographic measurements were recorded. All complications were sought and described, as well as surgical revisions. Several variables were analyzed to identify risk factors for revision surgery after SKp: age, sex, initial traumatic mechanism, initial non-surgical or surgical treatment and type of surgery, time until revision surgery with SKp after the initial trauma. RESULTS: Thirty-seven patients were included. At a median follow-up of 9.5 years (min 7.3 - max 11.5), 22 patients (60\%) had a VAS of 0. Range of motion was significantly improved for all the patients (p{\textless}0.001). Seventeen (46\%) patients had a complication, including 5 (13.4\%) cases of ossification, 4 (10.8\%) cases of discomfort related to the hardware and 4 (10.8\%) painful instability at the proximal ulnar stump. Thirteen (35\%) patients required revision surgery. Two risk factors for revision surgery after SKp were found: time period between initial treatment and SKp of less than 7.2 months and an age of less than 53.5 years; the combination of the two factors having a sensitivity of 97.5 and a specificity of 56.7. CONCLUSION: SKp in a post-traumatic context significantly improved range of motion and allowed pain control at long follow-up. Revision surgery seemed more frequent in patients under 53.5 years of age and when SKp was performed less than 7.2 months after the initial trauma.

Information is not always directly available in the source database and needs to be computed afterwards with raw data for defining an algorithm. OBJECTIVE: The main purpose of this article is to present a standardized description of the steps and transformations required during the feature extraction process when conducting retrospective observational studies. A secondary objective is to identify how the features could be stored in the schema of a data warehouse. METHODS: This study involved the following 3 main steps: (1) the collection of relevant study cases related to feature extraction and based on the automatic and secondary use of data; (2) the standardized description of raw data, steps, and transformations, which were common to the study cases; and (3) the identification of an appropriate table to store the features in the Observation Medical Outcomes Partnership (OMOP) common data model (CDM). RESULTS: We interviewed 10 researchers from 3 French university hospitals and a national institution, who were involved in 8 retrospective and observational studies. Based on these studies, 2 states (track and feature) and 2 transformations (track definition and track aggregation) emerged. "Track" is a time-dependent signal or period of interest, defined by a statistical unit, a value, and 2 milestones (a start event and an end event). "Feature" is time-independent high-level information with dimensionality identical to the statistical unit of the study, defined by a label and a value. The time dimension has become implicit in the value or name of the variable. We propose the 2 tables "TRACK" and "FEATURE" to store variables obtained in feature extraction and extend the OMOP CDM. CONCLUSIONS: We propose a standardized description of the feature extraction process. The process combined the 2 steps of track definition and track aggregation. By dividing the feature extraction into these 2 steps, difficulty was managed during track definition. The standardization of tracks requires great expertise with regard to the data, but allows the application of an infinite number of complex transformations. On the contrary, track aggregation is a very simple operation with a finite number of possibilities. A complete description of these steps could enhance the reproducibility of retrospective studies.}, language = {eng}, number = {10}, journal = {JMIR medical informatics}, author = {Lamer, Antoine and Fruchart, Mathilde and Paris, Nicolas and Popoff, Benjamin and Payen, Anaïs and Balcaen, Thibaut and Gacquer, William and Bouzillé, Guillaume and Cuggia, Marc and Doutreligne, Matthieu and Chazard, Emmanuel}, month = oct, year = {2022}, pmid = {36251369}, pmcid = {PMC9623460}, keywords = {Observation Medical Outcomes Partnership, algorithm, data reuse, data warehouse, database, feature extraction}, pages = {e38936}, }

Failure to prescribe the right test can lead to serious diagnostic errors. Furthermore, unnecessary medical tests are a waste of money and could possibly generate injuries to patients, especially in family medicine. METHODS: In an effort to improve the training of our students to the choice of laboratory and imaging studies, we implemented a specific multiple-choice questions (MCQ), called comprehensive MCQ (cMCQ), with a fixed and high number of options matching various basic medical tests, followed by a certainty-based mark (CBM). This tool was used in the assessment of diagnostic test choice in various clinical cases of general practice in 456 sixth-year medical students. RESULTS: The scores were significantly correlated with the traditional exams (standard MCQ), with matched themes. The proportion of "cMCQ/CBM score" variance explained by "standard MCQ score" was 21.3\%. The cMCQ placed students in a situation closer to practice reality than standard MCQ. In addition to its usefulness as an assessment tool, those tests had a formative value and allowed students to work on their ability to measure their doubt/certainty in order to develop a reflexive approach, required for their future professional practice.

METHODS: We analyzed data on patients with T2DM collected by three family physicians in Tourcoing (France) from 2006 to 2018. RESULTS: 403 patients, 1030 treatment sequences, 39,042 appointments, 2440 glycated hemoglobin (HbA1c) measurements, and 9722 wt measurements were included.

Although these integrated care pathways should be coordinated by GPs their level of commitment may vary. AIM: To profile GPs who had participated or had declined to participate in the Personnes Agées En Risque de Perte d'Autonomie (PAERPA) integrated care project (ICP) in the Valenciennois-Quercitain area of France between 2014 and 2019. DESIGN AND SETTING: A combined qualitative and quantitative analysis of GPs who were participating in or had declined to participate in the PAERPA ICP. METHOD: Both GPs participating in the ICP and GPs who chose not to participate in the ICP were interviewed, and then consultation and prescription profiles for these two groups were compared. RESULTS: Some GPs were interested in the PAERPA ICP, whereas others were opposed. The 48 qualitative interviews revealed four issues that influenced participation in the PAERPA ICP: 1) awareness of issues in care of older adults and the value of collaborative work; 2) time saving; 3) task delegation; and 4) advantages of coordination. The level of interest in the ICP for frail older adults was indirectly reflected by the data on consulting and prescribing. In GPs who participated in the PAERPA ICP there was a greater proportion of older (aged ≥70 years) patients (P{\textless}0.05), a larger number of consultations per year (P{\textless}0.05), and a larger number of home visits (P{\textless}0.01), relative to GPs who declined to participate.

METHODS: A multi-reader, multi-case study with cross-over design, was performed, including 314 mammograms. Twelve radiologists interpreted the examinations in two sessions delayed by a 4 weeks wash-out period with and without AI support. For each breast of each mammogram, they had to mark the most suspicious lesion (if any) and assign it with a forced BI-RADS category and a level of suspicion or "continuous BI-RADS 100". Cohen's kappa correlation coefficient evaluating the inter-observer agreement for BI-RADS category per breast, and the area under the receiver operating characteristic curve (AUC), were used as metrics and analyzed. RESULTS: On average, the quadratic kappa coefficient increased significantly when using AI for all readers [κ = 0.549, 95\% CI (0.528-0.571) without AI and κ = 0.626, 95\% CI (0.607-0.6455) with AI].

METHOD: We collected discussions on a French forum for AAS users (MESO-Rx®), from January 2013 to 2019 on concerning clomiphene, tamoxifen, anastrozole, exemestane and letrozole were collected. Characteristics of the users, duration of cures, treatments, dosages, point of purchase and occurrence of ADRs were analysed. RESULTS: Among the 1792 posts published on the forum, 845 concerned SERM and 571 concerned AI, i.e. 2180 drugs used (several cycles included concomitant consumption). Our population was exclusively male, with an average age of 28.2±6.3years, and had been practising weight training for 6.7±5.6years. The SERMs were mainly used to "revive the hypothalamohypophyseal axis" and the AIs to "fight against androgen aromatisation". The median treatment duration was 22 days for SERM, 70days for anastrozole, 84days for exemestane and 30days for letrozole, with a mean dose of 69mg/d for clomiphene, 22mg/d for tamoxifen, 0.4mg/d for anastrozole, 10mg/d for exemestane, 2mg/d for letrozole.

Le développement de nouveaux modules est cependant guidé par la technologie, et non par les besoins, ce qui amène à des produits parfois incohérents. Notre objectif est d'identifier ces besoins. Méthodes Nous avons envoyé un questionnaire papier à 200 MG tirés au sort sur le territoire, avec enveloppe retour prétimbrée. Les sondés ont tous été relancés par téléphone à deux semaines. Résultats Parmi les sondés, 139 MG (69,5 \%) ont répondu. Treize étant de pauvre qualité, 126 réponses ont été analysées. Caractéristiques des répondants: 66 femmes (52,4 \%), âge moyen 47,8 ans (SD=11,2), 88 en cabinet de groupe (71,0 \%), 90 en ville (71,4 \%). Les MG déclarent désirer des modules qui permettent de (par intérêt décroissant): - poser ou éliminer un diagnostic urgent - poser un diagnostic pour lequel le MG n'est pas compétent, ou aucun spécialiste n'est disponible - enregistrer automatiquement l'information dans le dossier patient, la partager avec un autre professionnel - simplifier un acte, passer plus de temps avec le patient, déléguer des tâches au secrétariat - exercer une médecine personnalisée, prédire un niveau de risque - impliquer et rassurer le patient - couper court à des demandes abusives (certificats de complaisance, arrêts de travail) - former le MG. Les MG rejettent les modules qui déclencheraient automatiquement un appel au 15, décideraient automatiquement, interviendraient dans leur champ de compétence, ou pourraient être utilisés par le patient lui-même en salle d'attente. Les MG sont indifférents aux autres items proposés. De nombreuses caractéristiques dépendent du profil (sexe, âge, lieu d'exercice).

Des voies d'optimisation pourraient être: qualité du contenu (exhaustivité, structuration), compréhension par les patients (schéma explicatif), rédaction (production semi-automatisée), transmission et stockage (interopérabilité). Nous avons imaginé le projet "ICIPEMIR" (« Improving the completeness, interoperability and patients explanation of medical imaging reports »), afin d'améliorer la production des compte rendus d'imagerie médicale. Nous décrivons ici la partie médicale et académique de ce projet, visant à de déterminer les informations nécessaires à chaque type de compte rendu d'imagerie. Méthodes Nous proposons une méthodologie reproductible pour identifier -pour un type d'examen- les champs nécessaires au compte rendu. Ils doivent répondre aux exigences légales, aux recommandations de sociétés savantes du domaine, et à une revue de littérature du domaine. Puis un modèle de donnée est successivement établi à partir de ces champs (UML, JSON Schema, YAML). Basé sur ce modèle de données, un formulaire est généré en utilisant l'outil open source d'e-CRF Goupile. De plus, une représentation graphique est modélisée, en lien avec le modèle de données, de même qu'un modèle de document textuel. Enfin, l'instance YAML est encodée dans un QR-Code pour permettre une transmission (re-)matérialisée des données structurées.

Méthodes Une méthode d'appariement semi-déterministe entre les données de l'entrepôt de données hospitalières du CHU de Rennes et celles du SNDS a été développée à partir des variables du PMSI entre 2015 et 2017.

Les fichiers ont été comparés sur le nombre de caractères, puis les données ont été intégrées dans un QR-Code. Afin de réduire la taille des fichiers avant intégration dans le QR-Code, nous avons comparé quatre algorithmes de compression. Les algorithmes de compression décompression étaient comparés sur la vitesse d'exécution et le ratio de compression. La faisabilité de l'utilisation du QR-Code était testée avec un décodage « digital » (analyse du fichier image), et physique (Scan par smartphone du QR-Code imprimé de taille progressivement décroissante).

To solve these problems, three-dimensional printing seems to be an appropriate educative material. In this study, the authors conducted a randomized controlled trial. The authors' main objective was to compare the performance of the undergraduate medical students in an examination based on the teaching support: three-dimensionally printed models versus two-dimensional pictures. METHODS: All participants were randomly assigned to one of two groups using a random number table: the three-dimensionally-printed support group (three-dimensional group) or the two-dimensionally-displayed support group (two-dimensional group). All participants completed a multiple-choice question evaluation questionnaire on facial traumatology (first, a zygomatic bone fracture; then, a double mandible fracture). Sex and potential confounding factors were evaluated. RESULTS: Four hundred thirty-two fifth-year undergraduate medical students were enrolled in this study. Two hundred six students were allocated to the three-dimensional group, and 226 were allocated to the two-dimensional group. The three-dimensionally printed model was considered to be a better teaching material compared with two-dimensional support. The global mean score was 2.36 in the three-dimensional group versus 1.99 in the two-dimensional group (p = 0.008). Regarding teaching of biomechanical aspects, three-dimensionally-printed models provide better understanding (p = 0.015). Participants in both groups exhibited similar previous student educational achievements and visuospatial skills.

Initially, the often difficult physical examination provides limited information, creating a risk of missing cruciate-ligament injuries, which can result in substantial functional impairments. No simple tool is available to emergency and primary-care physicians for decisions regarding specialist referral of patients with knee ligament sprains. An easy to use clinical score for the emergency setting would help identify patients at high risk of anterior cruciate ligament (ACL) tears after knee ligament sprains. The primary objective of this study, in two separate cohorts with acute knee injuries, was to develop, then validate a score for assessing the probability of ACL tear and, therefore, the need for specialist referral. HYPOTHESIS: A score based on patient-interview information with a cut-off associated to good sensitivity and positive predictive value (PPV) for ACL tears can be developed. MATERIAL AND METHODS: A literature review identified seven items to be used in the score: pivoting and contact activity at the time of injury, perceived cracking sound, sensation of dislocation, joint effusion, suggestive mechanism, inability to resume the activity, and immediate sensation of instability upon walking. To select the most relevant items, we recruited a development cohort of 228 patients (127 males and 101 females) with a mean age of 32±9 years who were seen for knee injuries between November 2017 and November 2018 at three healthcare institutions; 183 (80\%) had ACL tears. The score was then tested in a validation cohort of 121 patients (79 males and 42 females) with a mean age of 28±2.5 years seen at two healthcare institutions between November 2019 and November 2020; 81 (67\%) had ACL tears. In all patients, the diagnosis of ACL tear was confirmed by a specialist examination and magnetic resonance imaging. RESULTS: Four items proved both sensitive and specific for ACL injury and were combined into the score: an immediate sensation of knee instability, an inability to resume the sports activity, a sensation of dislocation, and injury during a pivoting-contact activity. Patient report of two or more of these four criteria had 96\% sensitivity and 66\% specificity for ACL tear, with a PPV of 91\% and an NPV of 83\%. Results were similar in the validation cohort, confirming that a cut-off of at least two of the four items strongly suggested an ACL tear, with 94\% sensitivity, 56\% specificity, a PPV of 82\% and an NPV of 82\%. CONCLUSION: The ACLIS score performs well for the emergency-room diagnosis of ACL tear, with 95\% sensitivity, 62\% specificity, an 88\% PPV, and an 82\% NPV. Patients with ACLIS scores of 2 or more probably require specialist referral with or without magnetic resonance imaging. The ACLIS score could be used routinely in emergency departments to decrease the proportion of patients with undiagnosed ACL tears.

The aim of the INSHARE (Integrating and Sharing Health Big Data for Research) project was to provide the blueprint for a technological platform that facilitates integration, sharing, and reuse of data from 2 sources: the clinical data warehouse (CDW) of the Rennes academic hospital, called eHOP (entrepôt Hôpital), and a data set extracted from the French national claim data warehouse (Système National des Données de Santé [SNDS]). OBJECTIVE: This study aims to demonstrate how the INSHARE platform can support big data analytic tasks in the health field using a pharmacovigilance use case based on statin consumption and statin-drug interactions. METHODS: A Spark distributed cluster-computing framework was used for the record linkage procedure and all analyses. A semideterministic record linkage method based on the common variables between the chosen data sources was developed to identify all patients discharged after at least one hospital stay at the Rennes academic hospital between 2015 and 2017. The use-case study focused on a cohort of patients treated with statins prescribed by their general practitioner or during their hospital stay. RESULTS: The whole process (record linkage procedure and use-case analyses) required 88 minutes. Of the 161,532 and 164,316 patients from the SNDS and eHOP CDW data sets, respectively, 159,495 patients were successfully linked (98.74\% and 97.07\% of patients from SNDS and eHOP CDW, respectively). Of the 16,806 patients with at least one statin delivery, 8293 patients started the consumption before and continued during the hospital stay, 6382 patients stopped statin consumption at hospital admission, and 2131 patients initiated statins in hospital. Statin-drug interactions occurred more frequently during hospitalization than in the community (3800/10,424, 36.45\% and 3253/14,675, 22.17\%, respectively; P{\textless}.001). Only 121 patients had the most severe level of statin-drug interaction. Hospital stay burden (length of stay and in-hospital mortality) was more severe in patients with statin-drug interactions during hospitalization.

DESIGN: We performed an observational study of out-of-hospital cardiac arrest patients between March 2020 and December 2020. Coronavirus disease 2019 status (confirmed, suspected, or negative) was defined according to the World Health Organization's criteria. SETTING: Information on the patients and their care was extracted from the French national out-of-hospital cardiac arrest registry. The French prehospital emergency medical system has two tiers: the fire department intervenes rapidly to provide basic life support, and mobile ICUs provide advanced life support. The study data (including each patient's coronavirus disease 2019 status) were collected by 95 mobile ICUs throughout France. PATIENTS: We included 6,624 out-of-hospital cardiac arrest patients: 127 cases with confirmed coronavirus disease 2019, 473 with suspected coronavirus disease 2019, and 6,024 negative for coronavirus disease 2019. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The "confirmed" and "suspected" groups of coronavirus disease 2019 patients had similar characteristics and were more likely to have suffered an out-of-hospital cardiac arrest with a respiratory cause (confirmed: 53.7\%, suspected coronavirus disease 2019: 56.5\%; p = 0.472) than noncoronavirus disease 2019 patients (14.0\%; p {\textless} 0.001 vs confirmed coronavirus disease 2019 patients). Advanced life support was initiated for 57.5\% of the confirmed coronavirus disease 2019 patients, compared with 64.5\% of the suspected coronavirus disease 2019 patients (p = 0.149) and 70.6\% of the noncoronavirus disease 2019 ones (p = 0.002). The survival rate at 30-day postout-of-hospital cardiac arrest was 0\% in the confirmed coronavirus disease 2019 group, 0.9\% in the suspected coronavirus disease 2019 group (p = 0.583 vs confirmed), and 3.5\% (p = 0.023) in the noncoronavirus disease 2019 group.

While the rate of suicide after deliberate self-harm has been evaluated in meta-analyses, the specific rate of death by suicide after a previous suicide attempt has never been assessed. The aim of our study was to estimate the incidence of death by suicide after a nonfatal suicide attempt. METHOD: We developed and followed a standard meta-analysis protocol (systematic review registration-PROSPERO 2021: CRD42021221111). Randomized controlled trials and cohort studies published between 1970 and 2020 focusing on the rate of suicide after suicide attempt were identified in PubMed, PsycInfo and Scopus and qualitatively described. The rates of deaths by suicide at 1, 5 and 10 years after a nonfatal suicide attempt were pooled in a meta-analysis using a random-effects model. Subgroup analysis and meta-regressions were also performed. RESULTS: Our meta-analysis is based on 41 studies. The suicide rate after a nonfatal suicide attempt was 2.8\% (2.2-3.5) at 1 year, 5.6\% (3.9-7.9) at 5 years and 7.4\% (5.2-10.4) at 10 years. Estimates of the suicide rate vary widely depending on the psychiatric diagnosis, the method used for the suicide attempt, the type of study and the age group considered. CONCLUSION: The evidence of a high rate of suicide deaths in the year following nonfatal suicide attempts should prompt prevention systems to be particularly vigilant during this period.}, language = {eng}, journal = {The Australian and New Zealand Journal of Psychiatry}, author = {Demesmaeker, Alice and Chazard, Emmanuel and Hoang, Aline and Vaiva, Guillaume and Amad, Ali}, month = sep, year = {2021}, pmid = {34465221}, keywords = {Suicide attempt, epidemiology, mortality, suicide}, pages = {48674211043455}, }

We describe and evaluate the original RELP (Retrograde Extraperitoneal Laparoscopic Prostatectomy). MATERIALS AND METHODS: A prospective cohort of 1005 patients with clinical localized cancer prostate were operated from December 1999 to September 2013, in Lyon (France), and followed up to 172 months (median: 60 months). Patients encountered a RELP procedure, a totally extra-peritoneal approach with a retrograde dissection from the apex to the bladder neck, and ascending dissection of the erectile neurovascular bundles, facilitated by the 30° optic telescope. Adjunctive treatments were: immediate radiotherapy (9.2\%), salvage radiotherapy (13.4\%), androgen deprivation therapy (10.8\%), chemotherapy (1.4\%), no treatment (75.8\%). Results The mean age was 63.4, the Gleason score was 4+3 or worse in 24.9\%, there were 2.3\% unifocal tumors. The pathology stages were pT2A (8.71\%), pT2B (2.80\%), pT2C (69.0\%), pT3A (13.1\%), and pT3B (6.41\%). There were 60.8\% negative margins (R0) in total (90.1\% for basal locations, and 75.8\% for apical locations). The mean operating time was 115 minutes for the last 100 patients. The BPFSR (biological progression free survival rate, PSA≤0.10 ng/ml) was 71.9\% at 5 years, and 61.4\% at 10 years. The cancer specific survival rate was 99.4\% at 5 years, and 98.3\% at 10 years.

Possible areas for improvement would be: to improve reports quality (by increasing exhaustivity), to improve patients' understanding (by mean of a graphical display), to save physicians' time (by helping reports writing), and to improve sharing and storage (by enhancing interoperability). We set up the ICIPEMIR project (Improving the completeness, interoperability and patients explanation of medical imaging reports) as an academic solution to optimize medical imaging reports production. Such a project requires two layers: one engineering layer to build the automation process, and a second medical layer to determine domain-specific data models for each type of report. We describe here the medical layer of this project. METHODS: We designed a reproducible methodology to identify -for a given medical imaging exam- mandatory fields, and describe a corresponding simple data model using validated formats. The mandatory fields had to meet legal requirements, domain-specific guidelines, and results of a bibliographic review on clinical studies. An UML representation, a JSON Schema, and a YAML instance dataset were defined. Based on this data model a form was created using Goupile, an open source eCRF script-based editor. In addition, a graphical display was designed and mapped with the data model, as well as a text template to automatically produce a free-text report. Finally, the YAML instance was encoded in a QR-Code to allow offline paper-based transmission of structured data. RESULTS: We tested this methodology in a specific domain: computed tomography for urolithiasis. We successfully extracted 73 fields, and transformed them into a simple data model, with mapping to a simple graphical display, and textual report template. The offline QR-code transmission of a 2,615 characters YAML file was successful with simple smartphone QR-Code scanner. CONCLUSION: Although automated production of medical report requires domain-specific data model and mapping, these can be defined using a reproducible methodology.

The objective of the study was to implement an AKI detection rule based on KDIGO criteria in a CDSS and to optimize this rule to increase its relevance in clinical pharmacy use. Two explicit rules were implemented in a CDSS (basic AKI rule and improved AKI rule), based on KDIGO criteria. Only the improved rule was optimized by a group of experts during the two-month study period. The CDSS provided 1,125 alerts on AKI situations (i.e. 643 were triggered for the basic AKI rule and 482 for the improved AKI rule). As the study proceeds, the pharmaceutically and medically relevance of alerts from the improved AKI rule increased.

The aim of the study was to evaluate the association between the risk of suicide reattempt within 6 and 14 months after a suicide attempt (SA) with the use of different classes of psychotropic drugs, combination pairs and treatment adequacy from inclusion through 6 and 14 months post-SA. METHOD: A prospective observational cohort of 972 subjects from the ALGOS study from January 2010 to February 2013 was used to evaluate the association of risk of suicide reattempt within 6 and 14 months with the use of different classes of psychotropic drugs (antidepressants, anxiolytics, antipsychotics, lithium, anticonvulsants, analgesics, opioid maintenance therapy and maintenance treatment for alcohol dependence). A multivariable Cox model was performed after imputation of missing data using the multiple imputation method. RESULTS: Our main results did not show an association between psychotropic drug use and suicide reattempt after 6 months of follow-up. We demonstrated that the use of benzodiazepines (HR = 1.87 [1.25; 2.81], p {\textless} 0.01) and hypnotics (HR = 1.49 [1.03; 2.17], p = 0.04) or a combination of both (HR = 1.80 [1.17; 2.72], p = 0.01) were associated with suicide reattempt within 14 months after a previous SA.

Several surgical treatment options are possible, and practice varies from one center to another. The objective of the present study was to describe the surgical management and outcomes of POP in France from 2008 to 2014. METHODS: We performed a retrospective cohort study of all patients operated on for POP from 2008 to 2014, according to the French national hospital discharge summary database. Patient characteristics, surgical approaches, concomitant hysterectomy and/or incontinence surgery, the length of stay, the proportion of day-case operations, and patient outcomes were analyzed. RESULTS: We analyzed 310,938 hospital stays with POP surgery between 2008 and 2014; 130,908 (42\%) of the operations took place in hospitals performing more than 100 prolapse surgical procedures per year. The proportion of day-case operations was low, but rose significantly from 1.2\% to 4.6\% during the study period. More than half of the operations featured a vaginal approach. The proportions of operations with concomitant hysterectomy or urinary incontinence surgery fell from 41.0\% to 36.1\% and from 33.0\% to 25.8\% respectively. The proportions of laparoscopic procedures increased. The mortality rate was stable (0.07\% for all years).

METHODS: A prospective observational cohort of 972 subjects, included from January 26, 2010, to February 28, 2013, was used to perform a survival tree analysis with all sociodemographic and clinical variables available at inclusion. The results of the decision tree were then used to define a simple predictive algorithm for clinicians. RESULTS: The results of survival tree analysis highlighted 3 subgroups of patients with an increased risk of suicide attempt or death by suicide within 6 months after suicide attempt: patients with alcohol use disorder and a previous suicide attempt with acute alcohol use (risk ratio [RR] = 2.92; 95\% CI, 2.08 to 4.10), patients with anxiety disorders (RR = 0.98; 95\% CI, 0.69 to 1.39), and patients with a history of more than 2 suicide attempts in the past 3 years (RR = 2.11; 95\% CI, 1.25 to 3.54). The good prognosis group comprised all other patients. CONCLUSIONS: By using a data-driven method, this study identified 4 clinical factors interacting together to reduce or increase the risk of recidivism.

Even though indications are now well-established little is still known about patient outcomes. Therefore, the purpose of our retrospective study was to: (1) describe the circumstances in which hip arthroscopies are being performed; (2) study arthroscopy and arthroplasty reoperation rates; (3) assess the incidence of readmissions for complications. HYPOTHESIS: Hip arthroscopy in France produced similar results to those observed in other countries. MATERIALS AND METHODS: We conducted a cohort study from January 2008 to December 2014 in the French population using the national hospital discharge database called "Programme de médicalisation des systèmes d'information (PMSI)." We included all admissions that had a hip arthroscopy code and analyzed readmissions for conversion to hip arthroplasty, revision hip arthroscopy and complications (without being able to provide detailed descriptions). Risk factors associated with conversion, revision and readmission for complications were studied after performing a population analysis. RESULTS: A total of 3,699 patients were included over a period of seven years. The mean age was 40 years, with women being significantly older (mean age of 43 years) than men (38 years) (p{\textless}0.05). The number of procedures increased from 240 in 2008 to 702 in 2014. Synovectomies (67.9\%; 2514/3699) and surgical bone procedures (acetabuloplasty or femoroplasty) (47.3\%; 1751/3699) were the main procedures performed during the primary arthroscopy. In total, 410 patients underwent a conversion to arthroplasty, 231 patients had a revision arthroscopy, and 126 patients suffered a complication. Five years after the index procedure, the conversion rate was 16.3\%, revision rate was 8.2\%, and readmission rate for a postoperative complication was 5\%. The main risk factor associated with conversions was [Hazard ratio (HR) and 95\% Confidence Index (CI)] an age between 40 and 79 years during the first arthroscopy [3.04 (2.40; 3.87) compared with the reference class of 25-39 years]. Patients between ages 16 to 24 years during the first arthroscopy (0.35 [0.20; 0.61] compared with the reference class of 25-39 years) had a decreased risk of conversion (HR and 95\% CI). The main risk factors associated with revisions were: synovectomies [1.90 (1.34; 2.70)] and surgical bone procedures on the femoral neck and/or the acetabulum [1.82 (1.36; 2.4)]. The risk factor associated with complication-related readmissions was an age greater than 40 years [2.23 (1.43; 3.49)]. CONCLUSION: Unlike the international literature, our study population was largely male. The rates of revision (8.2\% after five years) and conversion to arthroplasty (16.3\% after five years) were relatively low and comparable to the different international studies. This procedure, which is not widely performed, is growing in popularity, has low morbidity and remains an interesting approach given the revision and conversion rates after five years. The implementation of specific coding for arthroscopic hip procedures and the pathologies to be treated seems warranted.

However, the list of potential DDIs is long; the implementation of all these interactions in a clinical decision support system (CDSS) results in over-alerting and alert fatigue, limiting the benefits provided by the CDSS. OBJECTIVE: To estimate the probability of occurrence of international normalized ratio (INR) changes for each DDI rule, via the reuse of electronic health records. METHODS: An 8-year, exhaustive, population-based, historical cohort study including a French community hospital, a group of Danish community hospitals, and a Bulgarian hospital. The study database included 156,893 stays. After filtering against two criteria (at least one VKA administration and at least one INR laboratory result), the final analysis covered 4047 stays. Exposure to any of the 145 drugs known to interact with VKA was tracked and analyzed if at least 3 patients were concerned. The main outcomes are VKA potentiation (defined as an INR≥5) and VKA inhibition (defined as an INR≤1.5). Groups were compared using the Fisher exact test and logistic regression, and the results were expressed as an odds ratio (95\% confidence limits). RESULTS: The drugs known to interact with VKAs either did not have a statistically significant association regarding the outcome (47 drug administrations and 14 discontinuations) or were associated with significant reduction in risk of its occurrence (odds ratio{\textless}1 for 18 administrations and 21 discontinuations). CONCLUSIONS: The probabilities of outcomes obtained were not those expected on the basis of our current body of pharmacological knowledge. The results do not cast doubt on our current pharmacological knowledge per se but do challenge the commonly accepted idea whereby this knowledge alone should be used to define when a DDI alert should be displayed. Real-life probabilities should also be considered during the filtration of DDI alerts by CDSSs, as proposed in SPC-CDSS (statistically prioritized and contextualized CDSS).

The study's objective was to introduce a methodology to assess COVID-19 home deaths by analysing the French national out-of-hospital cardiac arrest (OHCA) registry (RéAC). METHODS: We performed a retrospective multicentre cohort study based on data recorded in the RéAC by 20 mobile medical teams (MMTs) between March 1st and April 15th, 2020. The participating MMTs covered 10.1\% of the French population. OHCA patients were classified as probable or confirmed COVID-19 cases or as non-COVID-19 cases. To achieve our primary objective, we computed the incidence and survival at hospital admission of cases of COVID-19 OHCA occurring at home. Cardiac arrests that occurred in retirement homes or public places were excluded. Hence, we estimated the number of at-home COVID-19-related deaths that were not accounted for in the French national statistics. RESULTS: We included 670 patients with OHCA. The extrapolated annual incidence of OHCA per 100,000 inhabitants was 91.9 overall and 17.6 for COVID-19 OHCA occurring at home. In the latter group, the survival rate after being taken to the hospital after an OHCA was 10.9\%.

Overall, 117 of the 1585 patients (7.4\%) were documented as having received systemic antibiotic therapy in hospital during the defined exposure period. The median overall survival time was shorter in patients with infection (6.3 months, vs. 15.4 months in patients without an infection; hazard ratio (HR) = 1.88, 95\% confidence interval [1.46; 2.43], p = 10-6). In a multivariate analysis adjusted for covariates, infection was still significantly associated with overall survival (HR = 1.68, [1.30; 2.18], p = 10-5). Conclusions: In patients treated with ipilimumab for advanced melanoma, infection, and antibiotic administration in hospital at around the time of the patient's first ever course of ipilimumab appears to be associated with significantly lower clinical benefit.}, language = {eng}, number = {1}, journal = {Oncoimmunology}, author = {Cren, Pierre-Yves and Bertrand, Nicolas and Le Deley, Marie-Cécile and Génin, Michaël and Mortier, Laurent and Odou, Pascal and Penel, Nicolas and Chazard, Emmanuel}, month = nov, year = {2020}, pmid = {33299658}, pmcid = {PMC7714497}, keywords = {Melanoma, antibiotics, data reuse, gut microbiota, immune checkpoint inhibitor, immunotherapy, infection, ipilimumab}, pages = {1846914}, }

Many methods have been proposed in the literature to reduce over-alerting of CDSS: enhancing post-alert medical management, taking into account user-related context, patient-related context and temporal aspects, improving medical relevance of alerts, filtering or tiering alerts on the basis of their strength of evidence, their severity, their override rate, or the probability of outcome. This paper analyzes the different options, and proposes the setup of SPC-CDSS (statistically prioritized and contextualized CDSS). The principle is that, when a SPC-CDSS is implemented in a medical unit, it first reuses actual clinical data, and searches for traceable outcomes. Then, for each rule trying to prevent this outcome, the SPC-CDSS automatically estimates the conditional probability of outcome knowing that the conditions of the rule are met, by retrospective secondary use of data. The alert can be turned off below a chosen probability threshold.

However, it is often difficult to display all data without inducing information overload. In both clinical usual care and medical research, users should be able to quickly find relevant information, with minimal cognitive overhead. Our goal was to devise simple visualization techniques for handling medical data in both contexts. METHODS: An abstraction layer for structured EHR data was devised after an informal literature review and discussions between authors. The "Heimdall" prototype was developed. Two experts evaluated the tool by answering 5 questions on 24 clinical cases. RESULTS: Temporal data was abstracted in three simple types: events, states and measures, with appropriate visual representations for each type. Heimdall can load and display complex heterogeneous structured temporal data in a straightforward way. The main view can display events, states and measures along a shared timeline. Users can summarize data using temporal, hierarchical compression and filters. Default and custom views can be used to work in problem- oriented ways. The evaluation found conclusive results.

The spatial distribution of hip fracture incidence was heterogeneous and there was a significant relationship between social deprivation, urbanization, health access, and hip fracture risk. INTRODUCTION: Several studies have shown great disparities in spatial repartition of hip fractures (HF). The aim of the study was to analyze the association between HF incidence and characteristics of the living area. METHODS: All patients aged 50 or older, living in France, who were hospitalized for HF between 2012 and 2014 were included, using the French national hospital discharge database. Standardized incidence ratio (SIR) was calculated for each spatial unit and adjusted on age and sex. An ecological regression was performed to analyze the association between HF standardized incidence and ecological variables. We adjusted the model for neighborhood spatial structure. We used three variables to characterize the living areas: a deprivation index (French-EDI); healthcare access (French standardized index); land use (percentage of artificialized surfaces). RESULTS: A total of 236,328 HF were recorded in the French hospital national database, leading to an annual HF incidence of 333/100,000. The spatial analysis revealed geographical variations of HF incidence with SIR varying from 0.67 (0.52; 0.85) to 1.45 (1.23; 1.70). There was a significant association between HF incidence rates and (1) French-EDI (trend p = 0.0023); (2) general practitioner and nurse accessibility (trend p = 0.0232 and p = 0.0129, respectively); (3) percentage of artificialized surfaces (p {\textless} 0.0001).

Data from large populations are lacking. We aimed to assess whether intraoperative administration of 6\% HES 130/0.4 is associated with AKI in non-cardiac surgery. METHODS: This retrospective study used the electronic records concerning elective abdominal, urologic, thoracic and peripheral vascular surgeries from 2010 to 2015. HES and non-HES patients were compared using a propensity score matching. Postoperative AKI, defined by stage 3 of the Kidney Disease Improving Global Outcomes (KDIGO) score, was the primary outcome. Because the use of HES markedly decreased in 2013, additional analyses, restricted to the 2010-2012 period, were also performed. RESULTS: 23 045, and 11 691 patients were included in the whole, and restricted periods, respectively. The reduction in HES use was not accompanied by any change in the incidence of AKI. Unadjusted association between HES and KDIGO 3 AKI was significant (OR [95\% CI] of 2.13 [1.67, 2.71]). For the whole period, 6460 patients were matched. Odd ratios for KDIGO 3 and all-stage AKI when using HES (10.3 ± 4.7 ml.kg-1 ) were 1.20 (95\% CI [0.74, 1.95]), and 1.21 (95\% CI [0.95, 1.54]), respectively.

Our primary objective was to assess the recurrence requiring reoperation after prolapse surgery, and our secondary objectives were to assess the early complications and secondary surgery for urinary incontinence. METHODS: Retrospective study of a population-based cohort of all hospital or outpatient stays including POP surgery from 2008 to 2014, using the French nationwide discharge summary database. We calculated the rates of hospital readmission following surgery as well as the rates of reoperation for recurrent prolapse and subsequent procedures performed for urinary incontinence. RESULTS: A total of 310,938 patients had undergone surgery for POP. Two hundred fourteen (0.07\%) patients died, and 0.45\% were admitted to an intensive care unit; 4.4\% of the patients underwent surgery for the recurrence of prolapse. Concomitant hysterectomy in the first surgery was associated with a significantly lower risk of POP surgery recurrence: (hazard ratio (HR) [95\% confidence interval (CI)] = 0.51 [0.49; 0.53]). A total of 1386 (2.5\%) patients were readmitted to the hospital for early (30-day) complications of prolapse surgery. The most frequent reasons for early readmission were local infection (32.8\%), hemorrhage (21.4\%) and pain (17.2\%). Risk factors for complications were obesity, hospitals with low levels of activity and associated incontinence surgery; 4.6\% of the patients required secondary surgery for urinary incontinence; obesity was a risk factor (HR [95\% CI] = 1.12 [1.01; 1.24]), and the vaginal route was a protective factor (odds ratio = 1.86 for laparoscopy, 1.44 for laparotomy and 1.25 for multiple approaches). CONCLUSIONS: POP surgery is associated with low rates of complication and recurrence. Complications occurred most commonly following combined surgeries for both prolapse and incontinence and in hospitals with low surgical volumes.

Moreover, CDMs provide tools for data quality assessment, integration into models, visualization, and analysis. The observational medical outcome partnership (OMOP) provides a CDM for organizing and standardizing databases. Common data models not only facilitate data integration but also (and especially for the OMOP model) extends the range of available statistical analyses. OBJECTIVE: This study aimed to evaluate the feasibility of implementing French national electronic health records in the OMOP CDM. METHODS: The OMOP's specifications were used to audit the source data, specify the transformation into the OMOP CDM, implement an extract-transform-load process to feed data from the French health care system into the OMOP CDM, and evaluate the final database. RESULTS: Seventeen vocabularies corresponding to the French context were added to the OMOP CDM's concepts. Three French terminologies were automatically mapped to standardized vocabularies. We loaded nine tables from the OMOP CDM's "standardized clinical data" section, and three tables from the "standardized health system data" section. Outpatient and inpatient data from 38,730 individuals were integrated. The median (interquartile range) number of outpatient and inpatient stays per patient was 160 (19-364). CONCLUSION: Our results demonstrated that data from the French national health care system can be integrated into the OMOP CDM. One of the main challenges was the use of international OMOP concepts to annotate data recorded in a French context. The use of local terminologies was an obstacle to conceptual mapping; with the exception of an adaptation of the International Classification of Diseases 10th Revision, the French health care system does not use international terminologies.

A number of serious adverse drug reactions are known to be associated with IFX use; they include infections, malignancies, and injection site reactions. Although a few case reports have described potential psychiatric adverse events (including suicide attempts and manic episodes), the latter are barely mentioned in IFX's summary of product characteristics. The objective of the present retrospective study was to detect potential psychiatric adverse events associated with IFX treatment by analyzing a national discharge abstract database. Materials and Methods: We performed an historical cohort study by analyzing data from the French national hospital discharge abstract database (PMSI) between 2008 and 2014. All patients admitted with one of the five diseases treated with IFX were included. Results: Of the 325,319 patients included in the study, 7,600 had been treated with IFX. The proportion of hospital admissions for one or more psychiatric events was higher among IFX-exposed patients (750 out of 7,600; 9.87\%) than among non-exposed patients (17,456 out of 317,719; 5.49\%). After taking account of potential confounders in the cohort as a whole, a semi-parametric Cox regression analysis gave an overall hazard ratio (HR) [95\% confidence interval] (CI) of 4.5 [3.95; 5.13] for a hospital admission with a psychiatric adverse event during treatment with IFX. The HR (95\%CI) for a depressive disorder was 4.97 (7.35; 6.68). Even higher risks were observed for certain pairs of adverse events and underlying pathologies: psychotic disorders in patients treated for ulcerative colitis (HR = 5.43 [2.01; 14.6]), manic episodes in patients treated for severe psoriasis (HR = 12.6 [4.65; 34.2]), and suicide attempts in patients treated for rheumatoid arthritis (HR = 4.45 [1.11; 17.9]). Discussion: The present retrospective, observational study confirmed that IFX treatment is associated with an elevated risk of psychiatric adverse events. Depending on the disease treated, physicians should be aware of these potential adverse events.}, language = {eng}, journal = {Frontiers in Pharmacology}, author = {Thillard, Eve-Marie and Gautier, Sophie and Babykina, Evgeniya and Carton, Louise and Amad, Ali and Bouzillé, Guillaume and Beuscart, Jean-Baptiste and Ficheur, Grégoire and Chazard, Emmanuel}, year = {2020}, pmid = {32390850}, pmcid = {PMC7188945}, keywords = {Adverse event (AE), Database (DB), Depression, Infliximab (ifx), Pharmacovigilance, Psychiatry, adverse events, database, depression, infliximab, pharmacoepidaemiology, pharmacoepidemiology, pharmacovigilance, psychiatry}, pages = {513}, }

However, how long the excess risk of postoperative pulmonary embolism persists remains unknown. Objective: To assess the duration and magnitude of the late postoperative risk of pulmonary embolism among cancer-free middle-aged patients by the type of surgery. Design, Setting, and Participants: Case-crossover analysis to compute the respective risks of pulmonary embolism after 6 types of surgery using data from a French national inpatient database, which covers a total of 203 million inpatient stays over an 8-year period between 2007 and 2014. Participants were cancer-free middle-aged adult patients (aged 45 to 64) with a diagnosis of a first pulmonary embolism. Exposures: Hospital admission for surgery. Surgical procedures were classified into 6 types: (1) vascular surgery, (2) gynecological surgery, (3) gastrointestinal surgery, (4) hip or knee replacement, (5) fractures, and (6) other orthopedic operations. Main Outcomes and Measures: Diagnosis of a first pulmonary embolism. Results: A total of 60 703 patients were included (35 766 [58.9\%] male; mean [SD] age, 56.6 [6.0] years). The risk of postoperative pulmonary embolism was elevated for at least 12 weeks after all types of surgery and was highest during the immediate postoperative period (1 to 6 weeks). The excess risk of postoperative pulmonary embolism ranged from odds ratio (OR), 5.24 (95\% CI, 3.91-7.01) for vascular surgery to OR, 8.34 (95\% CI, 6.07-11.45) for surgery for fractures. The risk remained elevated from 7 to 12 weeks, with the OR ranging from 2.26 (95\% CI, 1.81-2.82) for gastrointestinal operations to 4.23 (95\% CI, 3.01-5.92) for surgery for fractures. The risk was not clinically significant beyond 18 weeks postsurgery for all types of procedures. Conclusions and Relevance: The risk of postoperative pulmonary embolism is elevated beyond 6 weeks postsurgery regardless of the type of procedure. The persistence of this excess risk suggests that further randomized clinical trials are required to evaluate whether the duration of postoperative prophylactic anticoagulation should be extended and to define the optimal duration of treatment with regard to both the thrombotic and bleeding risks.}, language = {eng}, journal = {JAMA surgery}, author = {Caron, Alexandre and Depas, Nicolas and Chazard, Emmanuel and Yelnik, Cécile and Jeanpierre, Emmanuelle and Paris, Camille and Beuscart, Jean-Baptiste and Ficheur, Grégoire}, month = oct, year = {2019}, pmid = {31596449}, }

We calculated 200 indicators for different time and survival values, and selected the ones that maximized the area under the ROC curve (AUC) drawn by comparison against 4 chronic disease classifications: CCI, ALD, result from the analysis of ICD-10 labels, and a handmade list. The best indicator was the time to reach a survival of 4.5\%. It enables to get the following AUC: 78.9\% compared with CCI, 90.3\% compared with ALD, 75.1\% compared with labels analysis, and 91.5\% compared with the handmade list.

The objective of the present study was to measure immediate and delayed breast reconstruction (IBR and DBR, respectively) rates and thus the proportion of patients not benefiting from any reconstruction. METHODS: We performed an observational study by assessing data from the French nationwide discharge summary database (Programme de Médicalisation des Systèmes d'Information) for the period 2008-2014. All women having undergone a total mastectomy for breast cancer during this period were included. We then searched for reconstructive surgery during the initial or subsequent hospital stays, and recorded the time interval between mastectomy and reconstruction. RESULTS: Among the 140,904 mastectomies included, the IBR rate was 16.1\% on average, and increased over the study period. The time interval between mastectomy and DBR was≤3 years in 92\% of cases. For patients included in 2008 and 2009, the DBR rate was 17.8\%, and the non-reconstruction rate was 66.4\%. CONCLUSION: The high proportion of women not undergoing breast reconstruction after mastectomy suggests that access to this procedure should be improved.}, language = {eng}, journal = {Annales De Chirurgie Plastique Et Esthetique}, author = {Nègre, G. and Balcaen, T. and Dast, S. and Sinna, R. and Chazard, E.}, month = aug, year = {2019}, pmid = {31383624}, keywords = {Breast cancer, Breast reconstruction, Cancer du sein, Epidemiology, Mastectomie, Mastectomy, PMSI, Reconstruction mammaire, Épidémiologie}, }
