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.
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.
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).
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.
