Online Virtual Patient Cases vs. Weekly Classroom Lectures in an Internal Medicine Clerkship: Effects on Military Learner Outcomes.

Introduction Virtual patient cases (VPCs), a type of simulated, interactive electronic learning, are a potentially important tool for military health care providers in austere or pandemic settings to maintain skills but need more validation. Our military internal medicine clerkship is spread across military treatment facilities around the country and has 15 weekly live student lectures, but students randomly miss the first, second, or third 5 weeks due to their psychiatry clerkship. We hypothesized that VPCs would be an adequate replacement for lost lectures. Materials and Methods We compared live lectures to a web-based VPC and analyzed the academic outcomes of 734 students from 2015 to 2022. Results Using our end-of-clerkship Script Concordance Test (SCT) as the primary outcome, there was no significant difference in performance between the 2 learning methods (VPC, 63.9% correct; lectures 63.2%, P  = .27). After controlling for gender, baseline knowledge, and the total number of VPCs completed, there was still not a statistically significant difference between teaching methods (F (1,728) = 0.52, P  = .47). There was also no significant differences in all other clerkship outcomes including National Board of Medical Examiner and Objective Structured Clinical Examination scores. Conclusion VPCs appear noninferior at teaching clinical reasoning as measured by SCT. VPCs might be substituted for traditional, live lectures in clerkships when time or other resources are limited, in austere environments such as military deployments, or during conditions limiting interpersonal contact such as pandemics but are not a complete substitution for in-person learning.
