Rethinking gross anatomy in a compressed time frame: Clinical symptoms, not case studies, as the basis for...

The goal of this observational study was to develop effective approaches to introduce first year medical students to gross anatomy/embryology in a compressed time frame. Pedagogical reorganization of anatomy instruction in the regions of Lower Extremity and Head and Neck was based upon core clinical conditions taught in second-year and USMLE Step 1 board review courses. These conditions were not presented as clinical problems, as many students had limited prior training in medical terminology, but focused upon clinical symptoms, allowing for direct correlation of structure and function. Instruction stressed vocabulary acquisition and was extended to prepare for laboratory dissections. Overall methodology was multimodal, including "flipped" and traditional lectures, study of prosections/radiographs and small group laboratory review sessions. Content was significantly reduced: knowledge of muscle actions and innervations was required, not muscle origins and insertions. Performance was evaluated by criterion-based written examinations that included a set of questions (34) asked repetitively over an 8 year period (n = 606 students) and by regional practical exams. Mean scores in all areas were sustained or numerically improved, despite the compression of instruction duration. Analysis showed no significant differences based upon question format or instructional modality. Despite the high performance levels, students needing assistance in learning could be identified by score distributions. A survey of students indicated that these changes effectively decreased stress and facilitated review for the USMLE Step 1 Board examination. These results suggest that training in gross anatomy can be modified to a compressed duration by instruction in the context of clinical symptomatology.
