The #ObGynInternChallenge: Reach, Adoption, Implementation, and Effectiveness of a Microlearning SMS-Distributed Curriculum.

Problem: While many medical schools have implemented bootcamps or specialized curricula to prepare medical students for residency, these programs are neither universal nor consistent in their content.

Approach: The authors created an electronic, multimodal, short messaging service (SMS)-distributed curriculum, called the #ObGynInternChallenge, to improve learners' medical knowledge, based on the Council on Resident Education in Obstetrics and Gynecology educational objectives. The curriculum was open to all fourth-year medical students who matched into obstetrics and gynecology (Ob/Gyn). Daily messages were delivered to participants' mobile devices via SMS for 25 consecutive weekdays, May 3-June 4, 2021. Each day's message included an introduction with key facts, an infographic, a website link with a podcast and additional reference materials, and at least one question. The authors assessed its reach, adoption, implementation, and effectiveness.

Outcomes: For reach and adoption, total enrollment for the curriculum was 1,057 (72.0%) of 1,469 filled Ob/Gyn residency positions in the 2021 Match. The total cost of the intervention was $2,503.20 or $2.37 per participant. For implementation, all participants who signed up for the course received the daily messages, and 858/1,057 (81.2%) completed the course. Participants felt the curriculum was an excellent resource for studying (391/426, 91.8%) and the course was enjoyable to use (395/424, 93.2%). For effectiveness, mean score improvement was 11.6% (pre-test: 62.4%, post-test: 74.0%; P < .001). In the multivariate linear regression analysis, high podcast ( P = .02) and website use ( P = .002) were associated with greater score improvement. High social media use was associated with less improvement ( P = .02).

Next Steps: This study suggests promise for a low-cost, largely satisfying SMS-distributed curriculum in terms of offering some benefit for short-term knowledge gain. Next steps include expanding such a curriculum to meet standard learning objectives for all fourth-year medical students entering residency.
