Villatoro T, Lackritz K, Chan JSY. Case-Based Asynchronous Interactive Modules in Undergraduate Medical Education. Acad Pathol. 2019;6:2374289519884715.Undergraduate medical education traditionally consists of 2 years of lecture-based courses followed by 2 years of clinical clerkships. However, over the past couple decades, undergraduate medical education has been evolving toward non-lecture-based integrated curriculums, requiring a collaborative curriculum. Additionally, e-learning platforms have become efficacious and essential to delivering education asynchronously to students. At Thomas Jefferson University, the Pathology and Obstetrics and Gynecology departments collaborated to create a pilot series of case-based asynchronous interactive modules to teach gynecologic pathology in a clinical context, while interweaving other educational components, such as evidence-based medicine, clinical skills, and basic sciences. The case-based asynchronous interactive modules were given to third-year medical students during their obstetrics and gynecology clerkship. Students interpreted histologic and clinical images while being evaluated on clinical management skills, gynecologic diagnoses, general principles of population health and pathology. Sixty-eight students from 3 blocks completed a pre and posttest. All participants showed improvement in interpreting gynecologic pathology in routine clinical scenarios as well as improved case-based decision-making, with an average score increase by 5.7%.
