The influence of patient gender on medical students' care: Evaluation during an objective structured clinical examination.

OBJECTIVES: To assess whether men and women are evaluated and treated differently by medical students. METHODS: We evaluated patient care provided by 110 fifth-year medical students during an objective structured clinical examination (OSCE), using two clinical cases with standardized patients (SPs): generalized anxiety disorder (GAD) and ascending aortic dissection (AAD). Half of the students encountered male and half female SPs. Except for gender, the cases were identical. We compared diagnosis and treatment of male vs female SPs. RESULTS: Students diagnosed GAD more often in female SPs than in male SPs (diagnosis completed, partially completed, and not completed in 47%, 16% and 36% respectively vs. 22%, 20%, and 58% for male SPs, p = 0.02). The nature of symptoms was better described for male SPs. For AAD, the emergency was more frequently identified and the examination of femoral pulses better performed in female SPs. CONCLUSION: Medical students have a gender bias when evaluating patients with GAD and AAD. PRACTICE IMPLICATION: The observed gender bias in the evaluation of patients, likely leads to differences in treatment between male and female patients (i.e. under-recognition of anxiety in men). Medical schools should implement gender-sensitive medical education initiatives to improve inclusive patient care.

Entrustable professional activities for residency in general internal medicine: a systematic review.

CONTEXT: Entrustable Professional Activities (EPAs) are observable tasks that are regular parts of a physician's daily clinical work. Before being permitted to accomplish these tasks independently, trainees must gain their supervisors' trust. Defining the list of EPAs that should be mastered by the end of a residency is critical to setting clear expectations about autonomous practice. OBJECTIVE: To collect all the lists of EPAs defined for residencies in general internal medicine and synthesise them into a reference work useful for developing new lists of EPAs or improving existing ones. METHOD: This systematic review searched five databases and relevant grey literature using keywords related to EPAs and postgraduate education, from 2005, when the first article on EPAs was published, to April 2022. Inclusion criteria were the availability of an EPAs list and a focus on general internal medicine. Two reviewers independently selected the studies, extracted data and performed a quality assessment using QATSDD and AACODS tools. Mean values and inter-rater reliability were calculated. RESULTS: The review yielded 3292 records, with 16 articles meeting the inclusion criteria, mostly from North America. Synthesising their 16 lists generated 395 EPAs. The reviewers then inductively categoried those EPAs, 308 of which fell into 6 domains, 14 themes and 24 subthemes. The domains were: (1) care and management of the general adult population (n = 103 EPAs); (2) care and management of patients with specific needs (n = 67); (3) care coordination and communication (n = 52); (4) management and leadership (N = 21); (5) healthcare quality, education, and research (n = 41); and (6) miscellaneous (n = 24). The remaining 87 EPAs were disease-specific and did not fit into this categorisation. CONCLUSIONS: Categorising EPAs created a unique synthesis of the existing lists of EPAs for educating residents in general internal medicine. This synthesis could be used as a reference for anyone tasked with developing new lists of EPAs or improving existing ones.

[Teaching and learning during attending rounds in internal medicine: an anthropological study]. / Enseigner et apprendre lors des grandes visites en médecine interne hospitalière : Une étude anthropologique.

This anthropological research aims to highlight the educational approaches in action during attending rounds. The goal is to understand how specific learning domains, professional socialization and learning environments are influenced by the different ways of conducting attending rounds. Two formats of rounds were noted: the IN format, when the patient case is presented in the patient room, and the OUT format. Six educational approaches were identified. The attending round format has an impact on the approaches used. The latter contribute to the development, to varying degrees, of knowledge, skills and attitudes. Attending rounds remain a space for "top-down" transmission and supervision, even though some approaches involve learner initiatives and peer group logic.

Notre recherche anthropologique vise à mettre en lumière les approches pédagogiques à l'œuvre durant les grandes visites. Comment les domaines d'apprentissages visés, la socialisation professionnelle et l'environnement d'apprentissage sont-ils influencés par les différentes manières de les conduire ? Deux formes de visites sont retrouvées : la forme IN (le cas est présenté au lit du patient) et la forme OUT. Six approches pédagogiques ont été identifiées. La forme de grande visite influence les approches pédagogiques mobilisées. Celles-ci contribuent à développer, à des degrés variables, des savoirs, savoir-faire et savoir-être. Les grandes visites restent un espace de transmission « top-down ¼ et de surveillance, même si certaines approches encouragent les initiatives des apprenants ainsi que les logiques de groupes de pairs.

Essential steps in the development, implementation, evaluation and quality assurance of the written part of the Swiss federal licensing examination for human medicine.

Purpose: This report describes the essential steps in the development, implementation, evaluation and quality assurance of the written part of the Swiss Federal Licensing Examination for Human Medicine (FLE) and the insights gained since its introduction in 2011. Methods: Based on existing scientific evidence, international expertise, and experience gained from previous examinations, the FLE is developed by experts from all five medical faculties in Switzerland with the support of the Institute for Medical Education and is held simultaneously at five locations. The exam organisers document and review every examination held and continuously optimise the processes; they have summarised the results in this report. Results: The essential steps comprise the development, revision and translation of questions; construction of the exam and production of materials; candidate preparation; implementation and analysis. The quality assurance measures consist of guideline coherence in the development of the questions and implementation of the exam, revision processes, construction of the exam based on the national blueprint, multiphase review of the translations and exam material, and statistical analysis of the exam and the comments from candidates. The intensive collaboration, especially on the part of representatives from all the participating faculties and a central coordination unit, which provides methodological support throughout and oversees the analysis of the exam, has proven successful. Successfully completed examinations and reliable results in the eleven examinations so far implemented represent the outcomes of the quality assurance measures. Significant insights in recent years are the importance of appreciating the work of those involved and the central organisation of exam development, thus ensuring the long-term success of the process. Conclusion: Common guidelines and workshops, quality assurance measures accompanied by the continuous improvement of all processes, and appreciation of everyone involved, are essential to carrying out such an examination at a high-quality level in the long term.

Antibody response and intra-host viral evolution after plasma therapy in COVID-19 patients pre-exposed or not to B-cell-depleting agents.

Administration of plasma therapy may contribute to viral control and survival of COVID-19 patients receiving B-cell-depleting agents that impair humoral immunity. However, little is known on the impact of anti-CD20 pre-exposition on the kinetics of SARS-CoV-2-specific antibodies. Here, we evaluated the relationship between anti-spike immunoglobulin G (IgG) kinetics and the clinical status or intra-host viral evolution after plasma therapy in 36 eligible hospitalized COVID-19 patients, pre-exposed or not to B-cell-depleting treatments. The majority of anti-CD20 pre-exposed patients (14/17) showed progressive declines of anti-spike IgG titres following plasma therapy, contrasting with the 4/19 patients who had not received B-cell-depleting agents (p = 0.0006). Patients with antibody decay also depicted prolonged clinical symptoms according to the World Health Organization (WHO) severity classification (p = 0.0267) and SARS-CoV-2 viral loads (p = 0.0032) before complete virus clearance. Moreover, they had higher mutation rates than patients able to mount an endogenous humoral response (p = 0.015), including three patients with one to four spike mutations, potentially associated with immune escape. No relevant differences were observed between patients treated with plasma from convalescent and/or mRNA-vaccinated donors. Our study emphasizes the need for an individualized clinical care and follow-up in the management of COVID-19 patients with B-cell lymphopenia.

Development of health care workers' mental health during the SARS-CoV-2 pandemic in Switzerland: two cross-sectional studies.

BACKGROUND: Virus outbreaks such as the current SARS-CoV-2 pandemic are challenging for health care workers (HCWs), affecting their workload and their mental health. Since both, workload and HCW's well-being are related to the quality of care, continuous monitoring of working hours and indicators of mental health in HCWs is of relevance during the current pandemic. The existing investigations, however, have been limited to a single study period. We examined changes in working hours and mental health in Swiss HCWs at the height of the pandemic (T1) and again after its flattening (T2). METHODS: We conducted two cross-sectional online studies among Swiss HCWs assessing working hours, depression, anxiety, and burnout. From each study, 812 demographics-matched participants were included into the analysis. Working hours and mental health were compared between the two samples. RESULTS: Compared to prior to the pandemic, the share of participants working less hours was the same in both samples, whereas the share of those working more hours was lower in the T2 sample. The level of depression did not differ between the samples. In the T2 sample, participants reported more anxiety, however, this difference was below the minimal clinically important difference. Levels of burnout were slightly higher in the T2 sample. CONCLUSIONS: Two weeks after the health care system started to transition back to normal operations, HCWs' working hours still differed from their regular hours in non-pandemic times. Overall anxiety and depression among HCWs did not change substantially over the course of the current SARS-CoV-2 pandemic.

[Albumin substitution : A review of the indications in general internal medicine]. / Substitution en albumine : revue des indications en médecine interne générale.

Albumin has multiple physiological functions such as maintenance of oncotic pressure, binding of plasmatic molecule, immunomodulation and endothelial stabilization. Considering potential negative effects of hypoalbuminemia, the question of albumin substitution arises. For cirrhotic patients, indications for substitution are well established with a scientific consensus for spontaneous bacterial peritonitis, paracentesis-induced circulatory dysfunction and hepatorenal syndrome. However, in the case of hepatic encephalopathy or of hypoalbuminemia in non-cirrhotic patients, the scientific consensus is absent, and the results of clinical studies differ. In this article, we present the different indications of albumin substitution by examining the most recent studies.

L'albumine exerce de multiples fonctions physiologiques, notamment : maintien de la pression oncotique, liaison à d'autres molécules plasmatiques, immunomodulation et stabilisation endothéliale. Face aux potentiels effets délétères de l'hypoalbuminémie, la question d'une substitution se pose. Chez le patient cirrhotique, les indications à la substitution sont bien définies avec un consensus scientifique pour la péritonite bactérienne spontanée, la dysfonction circulatoire postparacentèse de grand volume et le syndrome hépatorénal. Néanmoins, en cas d'encéphalopathie hépatique ou d'hypoalbuminémie chez le patient non cirrhotique, le consensus est absent et les résultats des études divergent. Dans cet article, nous présentons les différentes indications à sa substitution, en mettant l'accent sur les études récentes en la matière.

Burnout, depression and anxiety among Swiss medical students - A network analysis.

It is well established that burnout in medical students is associated with depression and anxiety at a syndromal level. Moreover, there is an ongoing debate about the extent to which burnout overlaps with depression and anxiety. The emerging network approach to psychopathology offers a new perspective on the interrelations between mental disorders focusing on symptom-level association. In this cross-sectional study, we exploratively investigated the associations among burnout, depression, and anxiety in 574 swiss medical students using a network analytic approach for the first time. Symptoms of depression and anxiety were assessed with the Patient Health Questionnaire and Generalized Anxiety Disorder respectively. Burnout was assessed with two single-item questions, one referring to emotional exhaustion and the other to depersonalization. We found a dense network in which at least one dimension of burnout was related to eleven of the sixteen included symptoms. This suggests that burnout is closely related to depression and anxiety but also has its own characteristics. Notably, suicidal ideation was not associated with either emotional exhaustion or depersonalization after adjusting for the influence of the remaining symptoms of anxiety and depression. Hence, the well-documented relationship between burnout and suicidal ideation in medical students may be entirely mediated by the experience of anxiety and depression. Hence, the well-documented relationship between burnout and suicidal ideation in medical students might be fully mediated by the experience of anxiety and depression. The collection of the sample after the first wave of infections during the SARS-CoV2 pandemic and the non-representativeness of the investigated sample limit the study's generalizability.

Case Report: Stepwise Anti-Inflammatory and Anti-SARS-CoV-2 Effects Following Convalescent Plasma Therapy With Full Clinical Recovery.

In these times of COVID-19 pandemic, concern has been raised about the potential effects of SARS-CoV-2 infection on immunocompromised patients, particularly on those receiving B-cell depleting agents and having therefore a severely depressed humoral response. Convalescent plasma can be a therapeutic option for these patients. Understanding the underlying mechanisms of convalescent plasma is crucial to optimize such therapeutic approach. Here, we describe a COVID-19 patient who was deeply immunosuppressed following rituximab (anti-CD20 monoclonal antibody) and concomitant chemotherapy for chronic lymphoid leukemia. His long-term severe T and B cell lymphopenia allowed to evaluate the treatment effects of convalescent plasma. Therapeutic outcome was monitored at the clinical, biological and radiological level. Moreover, anti-SARS-CoV-2 antibody titers (IgM, IgG and IgA) and neutralizing activity were assessed over time before and after plasma transfusions, alongside to SARS-CoV-2 RNA quantification and virus isolation from the upper respiratory tract. Already after the first cycle of plasma transfusion, the patient experienced rapid improvement of pneumonia, inflammation and blood cell counts, which may be related to the immunomodulatory properties of plasma. Subsequently, the cumulative increase in anti-SARS-CoV-2 neutralizing antibodies due to the three additional plasma transfusions was associated with progressive and finally complete viral clearance, resulting in full clinical recovery. In this case-report, administration of convalescent plasma revealed a stepwise effect with an initial and rapid anti-inflammatory activity followed by the progressive SARS-CoV-2 clearance. These data have potential implications for a more extended use of convalescent plasma and future monoclonal antibodies in the treatment of immunosuppressed COVID-19 patients.

Physical and psychological health of medical students involved in the coronavirus disease 2019 response in Switzerland.

Students involved in the COVID-19 response reported a similar proportion of COVID-19 symptoms or confirmed diagnoses, but lower levels of anxiety, depression and burnout compared with their non-involved peers.

Patients' perspectives on interprofessional collaboration between health care professionals during hospitalization: a qualitative systematic review.

OBJECTIVE: The objective of this review was to gain a better understanding of the interprofessional collaboration between health care professionals from the patients' point of view during hospitalisation; the influence of interprofessional collaboration on patient care, safety, and well-being; and patients' perspectives of their role in the interprofessional collaboration process. INTRODUCTION: Interprofessional collaboration is a key factor in improving patient health care outcomes and safety through better communication between health care professionals, better teamwork, and better care coordination. However, implementing interprofessional collaboration in the clinical setting can prove complex. Patients are increasingly interested in becoming partners within the health care system. They have the potential to contribute to their own safety and to observe professionals during the care process, thus gaining a better understanding of the interprofessional collaboration process and facilitating changes in the behavior of health care professionals. INCLUSION CRITERIA: This review considered qualitative research and mixed-method studies. Participants were hospitalized patients. Studies were included when they explored i) patients' perceptions of interprofessional collaboration, ii) the influence of interprofessional collaboration on patients' care, safety, or well-being, or iii) patients' perceptions of their own role in interprofessional collaboration. Qualitative studies focusing only on the care process or families' points of view were excluded. METHODS: Searches of six databases including MEDLINE, CINAHL, Embase, Web of Science, PsycINFO, and Sociological Abstract, limited to English, French, and German were conducted from March 2017 to June 2018. Assessment of methodological quality of studies was performed using the JBI Qualitative Assessment and Review Instrument. Data were extracted using the standardized data extraction tool from JBI. Data synthesis following the JBI approach of meta-aggregation was performed. The level of confidence for each synthesized finding was established based on ConQual. RESULTS: A total of 22 studies were included, which resulted in 89 findings and 24 categories. Eight synthesized findings were generated: patients' perceptions of interprofessional collaboration based on personal experiences and observations; patients' experiences with effective or ineffective interprofessional communication; patients' experience with power imbalance and paternalistic attitudes; patients' perceptions of key factors for a confident relationship with the interprofessional health care team; patients' need for comprehension of discussions between health care professionals; patients' perceptions of their role in an interprofessional health care team; patients' perceptions of opportunities for empowerment in interprofessional health care teams; and patients' need for humanizing care from interprofessional health care teams. The level of confidence of synthesized findings varied from low to moderate according to ConQual. CONCLUSIONS: This systematic review synthesized the perspectives of hospitalized patients regarding interprofessional collaboration and their perceived role in collaborative practices. Hospitalized patients observe interprofessional collaboration, either directly or indirectly, and the way interprofessional collaboration is performed may impact both their care and their well-being. However, little evidence has been found regarding the impact of interprofessional collaboration on patient safety. Patients' perspectives on their perceived role is not unanimous; some patients want to play an active role in the collaborative process, whereas others prefer to trust the health care professionals' expertise. Health care professionals should consider patients' preferences and act accordingly regarding both the collaborative process and the inclusion of the patients in collaborative practices.

[Medical students at the bedside of COVID-19 patients†: motivations and challenges]. / Étudiant·e·s en médecine engagé·e·s au chevet des patient·e·s hospitalisé·e·s pour COVID-19 - Motivations et enjeux.

The SARS-CoV-2 pandemic is putting our healthcare system under exceptional pressure, given the number of affected patients. In a context of limited human healthcare resources, senior medical students represent a valuable workforce that can quickly be mobilized for patient care. This is the approach followed in Switzerland and other countries, in several outpatient structures or inpatient services, including the Department of Internal Medicine, of the Lausanne University Hospital (CHUV). In this article, we first give the floor to students who responded to our call. We conclude with important considerations in terms of students' clinical supervision. It is reminded that the involvement of students in the care of COVID-19 patients should only occur on a vo luntary basis.

La pandémie de COVID-19 met notre système de santé sous une pression exceptionnelle, au vu du nombre de patient·e·s atteint·e·s. Dans un contexte de ressources humaines médico-soignantes limitées, les étudiant·e·s en médecine avancé·e·s dans leur cursus représentent un renfort très précieux, rapidement mobilisable auprès des patient·e·s. C'est la démarche suivie en Suisse et ailleurs dans le monde par diverses structures ambulatoires ou services hospitaliers, dont le Service de médecine interne du Centre hospitalier universitaire vaudois (CHUV). Dans cet article, nous donnons tout d'abord la parole aux étudiant·e·s qui ont répondu à notre appel. Nous terminons par des considérations importantes quant à l'accueil et l'accompagnement de ces étudiant·e·s. Il est rappelé que l'engagement d'étudiant·e·s auprès de patient·e·s souffrant de COVID-19 devrait se faire sur une base volontaire uniquement.

[Organizational Impacts and Clinical Challenges of the COVID-19 Pandemic on a Swiss Tertiary Internal Medicine Department]. / Impacts organisationnels et défis cliniques de la pandémie COVID-19 pour un service hospitalier de médecine interne universitaire.

The rapid progression of COVID-19 is an organizational challenge for all hospitals. To secure the patient overflow, the Department internal medicine of the University Hospital of Lausanne increased nurse and medical workforces as well as bed capacity by 65 %, with extraordinary help from other departments. The implemented crisis management stood upon three pillars : a crisis management team, steering documents and internal communication. In this new form, the Department had already taken care of 442 COVID-19 admissions by April 16, 2020. Alongside organizational challenges, clinical issues such as rapid respiratory distress, clinical suspicions with negative PCR and treatment uncertainties in the absence of sufficient evidence were overcome. Despite the peak of the pandemic appearing to have passed, the next phase could be just as complicated.

La progression rapide du COVID-19 constitue un défi organisationnel pour tous les hôpitaux. Pour anticiper un afflux important de patients, le service de médecine interne du CHUV a ainsi augmenté ses forces de travail médico-soignantes et son nombre de lits de 65 % avec un soutien extraordinaire de toute l'institution. Pour opérer ces changements majeurs, l'organisation de crise mise en place s'est appuyée sur trois piliers : une cellule de conduite, des documents de pilotage et une communication interne. Sous cette nouvelle forme, le service a pris en charge 442 hospitalisations COVID-19 jusqu'au 16 avril 2020. Si les enjeux organisationnels ont été majeurs, la gestion des situations complexes, comme les manifestations respiratoires et les multiples incertitudes cliniques diagnostiques et thérapeutiques, ont été également une gageure. Le pic de la pandémie semble passé, mais la prochaine phase pourrait constituer un nouveau défi organisationnel.

[Psychogenic polydipsia†: a (still) unknown psychosomatic entity]. / Polydipsie psychogène†: une entité somato-psychiatrique (encore) méconnue.

Psychogenic polydipsia, as well referred to as «â€…potomania ¼, is a clinical entity that can be found in psychiatric as well as in physical care settings. Its diagnosis is based on the detection of an excessive fluid intake along with a polyuria, after excluding any potential somatic cause of this clinical presentation. Given the different somatic complications and care complexity, early detection and multidisciplinary interventions are necessary. This article offers a literature review on this topic.

La polydipsie psychogène, également dénommée «â€…potomanie ¼, est une entité clinique que l'on rencontre en milieu psychiatrique, ainsi qu'en milieu somatique. Son diagnostic se base sur la détection d'une consommation excessive d'eau et d'une polyurie, après exclusion de toute cause somatique pouvant être à l'origine du tableau clinique. Vu les diverses complications somatiques et la complexité de la prise en charge, la nécessité de la détection précoce et d'une approche pluridisciplinaire est primordiale. Cet article propose une revue de la littérature scientifique sur ce sujet.

[PROFILES: typical portrait of the future Swiss doctors]. / PROFILES: portrait-type de nos futurs médecins !

In each professional practice, a greater or lesser part of the activity is devoted to teaching. Indeed, the transmission of the medical knowledge is an essential objective for the training of students and residents, but also an opportunity to adapt one's own practices to the current context, since fast changes are not necessarily easy to follow and assimilate. If the relationship with Medical school is rather straightforward in the university hospitals, it is not always the same for those who are more distant, but whose participation in teaching is desired, and clearly growing. In this way, it is therefore crucial that everyone is informed about recent changes to the undergraduated learning objectives (PROFILES) and the resulting needs for educational reforms for all Medical schools in Switzerland.

Dans chaque pratique professionnelle, une part plus ou moins grande de l'activité est dévolue à l'enseignement. En effet, la transmission de l'art médical représente un objectif essentiel pour la formation des étudiant·e·s et des jeunes collègues, mais aussi une opportunité pour adapter ses pratiques au contexte actuel, car les changements, rapides, ne sont pas forcément faciles à assimiler. Si, dans les hôpitaux universitaires, le contact avec les Facultés de médecine est plutôt aisé, il n'en va pas toujours de même pour ceux qui en sont plus distants, mais dont la participation à l'enseignement est souhaitée et croissante. En ce sens, il apparaît crucial que tou·te·s soient informé·e·s sur les modifications récentes des objectifs d'apprentissage prégradué (PROFILES) et sur les réformes qui en découlent pour les Facultés de médecine en Suisse.

Clinical and biological determinants of P-wave duration: cross-sectional data from the population-based CoLaus|PsyCoLaus study.

OBJECTIVES: P-wave duration (PWD) is associated with the development of atrial arrhythmias, cardiovascular and all-cause mortality. With this study, we aimed to assess the distribution and determinants of PWD in the general population. DESIGN: Cross-sectional study using data collected between 2014 and 2016. SETTING: In the population-based cohort CoLaus|PsyCoLaus, Lausanne, Switzerland, we used 12-lead ECGs to measure PWD. Potential demographic, clinical and biological determinants of PWD were collected by questionnaire, anthropometry, blood pressure measurement and biological assays. PARTICIPANTS: Data from 3459 participants (55% women, 62±10 years, 93% Caucasian) were included. Participants were excluded if they presented with (1) no sinus rhythm or paced rhythm on the study ECG or Wolff-Parkinson-White ECG pattern; (2) missing or non-interpretable ECG; and (3) missing phenotypic data. PRIMARY OUTCOME MEASURE: Determine (1) the PWD distribution and (2) the demographic, clinical and biological determinants of PWD in a large population-based cohort. RESULTS: Median and IQR of PWD was 112 (102-120) ms . In the multivariable analyses, PWD was significantly associated with age (p<0.001) and height (p<0.001), with an adjusted regression coefficient (95% CI) of 0.29 ms/years (0.23 to 0.36) and 0.32 ms/cm (0.28 to 0.37), respectively. PWD, given thereafter in ms with adjusted mean±SE, was significantly (p<0.05) associated with (a) gender (woman 110.0±0.4; man 112.1±0.4), (b) body mass index (normal 110.1±0.4; overweight 110.9±0.4; obese 113.0±0.5), (c) abdominal obesity (no 110.5±0.3; yes 111.7±0.4) and (d) hypertension (no 110.4±0.3; yes 111.7±0.4). CONCLUSION: PWD is positively associated with age, height, male gender, obesity markers and hypertension. Clinical interpretation of PWD should take these factors into consideration.

[Visual diagnosis†: between medical education and advances in artificial intelligence]. / Le diagnostic visuel†: au carrefour de la pédagogie médicale et des progrès en intelligence artificielle.

The electrocardiogram, chest x-ray, and skin lesion interpretation are a diagnostic process that applies image analysis. Knowledge and sufficient clinical experience are necessary to achieve expertise in these fields. However, recent advances in medical informatics, particularly in deep learning, are challenging this diagnostic process and physicians' performance. Only a fraction of clinical diagnostic support based on artificial intelligence (AI) has been validated in a clinical environment, limiting its use at the patient's bedside. Gradual AI integration into medical practice will require that the physicians remain able to assess the strengths and limitations of these new algorithms.

La lecture d'un ECG, l'analyse d'une radiographie du thorax ou l'approche d'une lésion dermatologique mettent l'interprétation d'une image au centre de la démarche diagnostique. Elles imposent un apprentissage des bases théoriques nécessaires et une exposition suffisante en milieu clinique. Or, les avancées récentes en informatique médicale, en particulier du deep learning, remettent en question l'approche diagnostique classique, disputant leurs performances aux médecins. Cependant, seul un petit nombre d'études relatives à l'intelligence artificielle sont validées à ce jour dans un contexte clinique, limitant son usage au lit du patient. A l'avenir, l'intelligence artificielle pourra progressivement être introduite dans la pratique médicale, pour autant que les médecins eux-mêmes restent capables d'évaluer la qualité de l'aide au diagnostic proposée par le deep learning.

Effectiveness of a transition plan at discharge of patients hospitalized with heart failure: a before-and-after study.

AIMS: We evaluated the effectiveness of a multidisciplinary transition plan to reduce early readmission among heart failure patients. METHODS AND RESULTS: We conducted a before-and-after study in a tertiary internal medicine department, comparing 3 years of retrospective data (pre-intervention) and 13 months of prospective data (intervention period). Intervention was the introduction in 2013 of a transition plan performed by a multidisciplinary team. We included all consecutive patients hospitalized with symptomatic heart failure and discharged to home. The outcomes were the fraction of days spent in hospital because of readmission, based on the sum of all days spent in hospital, and the rate of readmission. The same measurements were used for those with potentially avoidable readmissions. Four hundred thirty-one patients were included and compared with 1441 patients in the pre-intervention period. Of the 431 patients, 138 received the transition plan while 293 were non-completers. Neither the fraction of days spent for readmissions nor the rate of readmission decreased during the intervention period. However, non-completers had a higher rate of the fraction of days spent for 30 day readmission (19.2% vs. 16.1%, P = 0.002) and for potentially avoidable readmission (9.8% vs. 13.2%, P = 0.001). The rate of potentially avoidable readmission decreased from 11.3% (before) to 9.9% (non-completers) and 8.7% (completers), reaching the adjusted expected range given by SQLape® (7.7-9.1%). CONCLUSIONS: A transition plan, requiring many resources, could decrease potentially avoidable readmission but shows no benefit on overall readmission. Future research should focus on potentially avoidable readmissions and other indicators such as patient satisfaction, adverse drug events, or adherence.
