Effect of shift-based scheduling on student learning, satisfaction and capacity in obstetrics and gynecology rotations

Objectives: Determine how a shift- based schedule to accommodate more students affects learning, performance, and satisfaction with the Obstetrics and Gynecology (OBG) rotation. Methods: The study was conducted among third year OBG medical students with a triangular convergent cross-sectional approach. A new shift-based schedule was implemented. After each rotation, an online survey was conducted using a convenience sampling. Student scores on the National Board of Medical Examiner (NBME) OBG subject exam were analyzed using paired t test. Survey data was analyzed using two sample t test. The relationship between survey responses and exam score findings were described. Data from shift-schedule students was compared to traditional schedule students from the prior academic year. Results: A statistically significant improvement was seen for average NBME score for shift-schedule students during the beginning portion (groups 1-3) of the academic year (M=80, SD=6.9) compared to traditional (M=75.7, SD=7.3) [t (145) =3.69, p =.001]. A similar pattern was not seen in subsequent groups (groups 4-6). Shift-schedule students also showed a statistically significant improvement in their perception of learning (t (183) =-2.54, p =.012). Parallel results were seen for belonging, manageable workload, time to study, and engaging meaningfully. Using this model, we increased rotation capacity from 24 to 30 students per group (20%). Conclusions: Shift based scheduling allows 20% increase in capacity. Exam scores and student learning outcomes were similar or better than traditional schedule controls.
