Web-based deliberate practice of pediatric point of care ultrasound cases in resource-limited settings

OBJECTIVES

The main objective of this study was to implement an online pediatric case‐based POCUS course in low‐resource medical settings and examine learning outcomes and feasibility.

METHODS

This was a multicenter prospective cohort study conducted in a convenience sample of clinicians affiliated with Médecins Sans Frontières (MSF) training sites. MSF POCUS trainers provided the standard hands‐on, on‐site POCUS training and supplemented this with access to a web‐based course. Participants provided diagnoses for 400 image‐based POCUS cases from four common pediatric POCUS applications until they achieved the mastery learning standard of 90% accuracy, sensitivity (cases with pathology), and specificity (cases without pathology). Each participant also completed a course evaluation.

RESULTS

From 10 MSF sites, 110 clinicians completed 82,206 cases. There were significant learning gains across the POCUS applications with respect to accuracy (delta 14.2%; 95% CI 13.1, 15.2), sensitivity (delta 13.2%; 95% CI 12.1, 14.2), and specificity (delta 13.8%; 95% CI 12.7, 15.0). Furthermore, 90 (81.8%) achieved the mastery learning standard in at least one application, and 69 (62.7%) completed a course evaluation on at least one application for a total of 231 evaluations. Of these, 206 (89.2%) agreed/strongly agreed that the experience had relevance to their practice, met expectations, and had a positive user design. However, 59/110 (53.6%) clinicians reported a lack of protected time, and 54/110 (49.0%) identified challenges with accessing internet/hardware.

CONCLUSIONS

In resource‐limited MSF settings, implementing web‐based POCUS case practice demonstrated successful learning outcomes despite approximately half of the participants encountering significant technical challenges.
