Simulation Training Improves Diagnostic Performance on a Real Patient With Similar Clinical Findings

BACKGROUND Training on a cardiopulmonary simulator improves subsequent diagnostic performance on the same simulator. But data are lacking on transfer of learning. The objective of this study was to determine whether training on a cardiorespiratory simulator improves diagnostic performance on a real patient. METHODS We randomly allocated first-year medical students at the University of Calgary to simulator training in one of three clinical scenarios of acute-onset chest pain: pulmonary embolism with right ventricular strain but no murmur, symptomatic aortic stenosis, or myocardial ischemia causing mitral regurgitation. Simulation sessions ran for 20 min, after which participants had a standardized debriefing session and reviewed the physical findings. Immediately following the training sessions, students assessed the auscultatory findings of a real patient with mitral regurgitation. Our outcome measures were accuracy of identifying abnormal auscultatory findings and diagnosing the underlying cardiac abnormality (mitral regurgitation). RESULTS Eighty-six students participated in the study. Students trained on mitral regurgitation were more likely to identify and diagnose these findings on a real patient with mitral regurgitation than those who had trained on aortic stenosis or a scenario with no cardiac murmur. The accuracy (SD) of identifying clinical features of mitral regurgitation for these three groups was 74.0 (36.4) vs 56.2 (34.3) vs 36.8 (33.1), respectively (P = .0005), and for diagnosing mitral regurgitation, the accuracy was 68.0 (45.4) vs 51.6 (50.0) vs 29.9 (40.7), respectively (P = .01). CONCLUSIONS Simulator training on mitral regurgitation increases the likelihood of diagnosing this abnormality on a real patient.

The effect of simulator training on clinical skills acquisition, retention and transfer.

Context  Prior research has demonstrated that residents have poor clinical skills in cardiology and respirology. It is not clear how these skills can be improved because the number of patients with suitable clinical findings whose cooperation might help residents to better develop these clinical skills is limited.

Podcasting in Medical Education: Can We Turn This Toy into an Effective Learning Tool?.

Advances in information technology have changed how we deliver medical education, sometimes for the better, sometimes not. Technologies that were designed for purposes other than education, such as podcasting, are now frequently used in medical education. In this article, the authors discuss the pros and cons of adapting existing technologies for medical education, caution against limiting evaluation of technologies to the level of rater satisfaction, and suggest a research agenda for formally evaluating the role of existing and future technologies in medical education.
