Abstract

Background: Ultrasound imaging devices are becoming popular in clinical and teaching settings, but there is no systematic information on their use in medical education. We conducted a systematic review of hand-held ultrasound (HHU) devices in undergraduate medical education to delineate their role, significance, and limitations.
Methods: We searched Cochrane, PubMed, Embase, and Medline using the strategy: [(Hand-held OR Portable OR Pocket OR ¡°Point of Care Systems¡±) AND Ultrasound] AND (Education OR Training OR Undergraduate OR ¡°Medical Students¡± OR ¡°Medical School¡±). We retained 12 articles focusing on undergraduate medical education. We summarised the patterns of HHU use, pooled and estimated sensitivity, and specificity of HHU for detection of left ventricular dysfunction.
Results: Features reported were heterogeneous: training time (1?25 hours), number of students involved (1-an entire cohort), number of subjects scanned (27?211), and type of learning (self-directed vs. traditional lectures + hands-on sessions). Most studies reported cardiac HHU examinations, but other anatomical areas were examined, e.g. abdomen and thyroid. Pooled sensitivity 0.88 [95% confidence interval (CI) 0.83?0.92] and specificity 0.86 (95% CI 0.81?0.90) were high for the detection of left ventricular systolic dysfunction by students.
Conclusion: Data on HHU devices in medical education are scarce and incomplete, but following training students can achieve high diagnostic accuracy, albeit in a limited number of (mainly cardiac) pathologies. There is no consensus on protocols best-suited to the educational needs of medical students, nor data on long-term impact, decay in proficiency or on the financial implications of deploying HHU in this setting.
