摘要:Background and Objectives: Online curricular interventions in residency have been proposed to address challenges of time, cost, and curriculum consistency. This study is designed to determine the feasibility and effectiveness of a longitudinal, multisite online curriculum in integrative medicine (IMR) for residents. Methods: Residents from eight family medicine programs undertook the 200-hour online IMR curriculum. Their medical knowledge (MK) scores at completion were compared to a control group from four similar residency programs. Study and control groups were comparable in baseline demographics, and MK scores. Course completion, MK scores, and course evaluations were assessed. Results: Of 186 IMR residents, 76.9% met completion requirements. The IMR group showed statistically significant higher MK scores at residency completion, the control group did not (IMR: 79.2% vs. Control: 53.2% mean correct). Over three-fourths of IMR participants (range 79-92%) chose the top two rating categories for each course evaluation item. In an exit survey, ability to access the curriculum for 1 additional year and intention to utilize IM approaches after residency were the highest ranked items. Conclusions: The demonstrated feasibility, effectiveness, and positive evaluations of the IMR curriculum indicate that a multisite, online curricular intervention is a potentially viable approach to offering new curriculum with limited on-site faculty expertise for other family medicine residencies.
