摘要
IntroductionTeaching point-of-care ultrasonography (PoCUS) to medical students is resource intensive. Peer-assisted learning, where the teacher can be a medical student, may be a feasible alternative to expert-led learning. The objective of this systematic review and meta-analysis was to compare the PoCUS performance assessments of medical students receiving peer-assisted vs expert-led learning.MethodsThis study was submitted to PROSPERO (CRD42023383915) and reported with PRISMA guidelines. MEDLINE, Embase, ERIC, Education Source, Scopus, and Web of Science were searched from inception to November 2022. Inclusion criteria were studies comparing peer-assisted vs expert-led PoCUS teaching for undergraduate medical students. The primary outcome was performance assessment of PoCUS skills. Two reviewers independently screened citations and extracted data. The Cochrane risk-of-bias tool for randomized trials was used to assess study quality. Studies were included in the meta-analysis if mean performance assessment scores with standard deviations and sample sizes were available. A random-effects meta-analysis was conducted to estimate the accuracy score of practical knowledge test for each group. A meta-regression evaluated difference in mean scores.ResultsThe search yielded 2890 citations; 1417 unique citations remained after removing duplicates. Nine randomized-controlled studies conducted in Germany, USA, and Israel, with 593 participants, were included in the meta-analysis. The included studies assessed teaching of abdominal, cardiac, thoracic, musculoskeletal, and ocular PoCUS skills. Most studies had some risk-of-bias concerns. The estimate accuracy score after weighting is 0.56 (95% CI [0.47, 0.65]) for peer-assisted learning and 0.59 (95% CI [0.49, 0.69]) for expert-led learning. The regression coefficient estimate is 0.0281 (95% CI [- 0.1121, 0.1683]); P value is 0.69.ConclusionThis meta-analysis found that peer-assisted learning was a reasonable alternative to expert-led learning for teaching PoCUS skills to medical students. IntroductionL'enseignement de l'echographie au point d'intervention (PoCUS) aux etudiants en medecine necessite des ressources importantes. L'apprentissage assiste par les pairs, ou l'enseignant peut etre un etudiant en medecine, peut etre une alternative possible a l'apprentissage dirige par des experts. L'objectif de cette revue systematique et de cette meta-analyse etait de comparer les evaluations de performance PoCUS d'etudiants en medecine beneficiant d'un apprentissage assiste par des pairs par rapport a un apprentissage dirige par des experts.MethodesCette etude a ete soumise a PROSPERO (CRD42023383915) et rapportee selon les directives PRISMA. MEDLINE, Embase, ERIC, Education Source, Scopus et Web of Science ont ete recherches depuis leur creation jusqu'en novembre 2022. Les criteres d'inclusion etaient les etudes comparant l'enseignement du PoCUS assiste par des pairs a celui dirige par des experts pour les etudiants en medecine de premier cycle. Le principal resultat etait l'evaluation du rendement des competences PoCUS. Deux evaluateurs ont independamment examine les citations et extrait les donnees. L'outil Cochrane d'evaluation du risque de biais pour les essais randomises a ete utilise pour evaluer la qualite des etudes. Les etudes ont ete incluses dans la meta-analyse si les scores moyens d'evaluation des performances avec les ecarts types et la taille des echantillons etaient disponibles. Une meta-analyse a effets aleatoires a ete realisee pour estimer le score de precision du test de connaissances pratiques pour chaque groupe. Une meta-regression a evalue la difference dans les scores moyens.ResultatsLa recherche a donne lieu a 2890 citations ; 1417 citations uniques ont ete conservees apres suppression des doublons. Neuf etudes controlees randomisees menees en Allemagne, aux etats-Unis et en Israel, avec 593 participants, ont ete incluses dans la meta-analyse. Les etudes incluses ont evalue l'enseignement des competences PoCUS abdominales, cardiaques, thoraciques, musculo-squelettiques et oculaires. La plupart des etudes presentaient des risques de biais. Le score de precision estime apres ponderation est de 0,56 (IC a 95 % : [0,47, 0,65]) pour l'apprentissage assiste par les pairs et de 0,59 (IC a 95 % : [0,49, 0,69]) pour l'apprentissage dirige par des experts. L'estimation du coefficient de regression est de 0,0281 (IC a 95 % : [-0,1121, 0,1683]) ; la valeur P est de 0,69.ConclusionCette meta-analyse a montre que l'apprentissage assiste par les pairs etait une alternative raisonnable a l'apprentissage dirige par des experts pour enseigner les competences PoCUS aux etudiants en medecine.
