Multimodal educational model for the management of placenta accreta spectrum: Participants' perceived usefulness

OBJECTIVE: To evaluate the perceived educational value of a multimodal surgical training model designed to improve obstetricians' skills in managing placenta accreta spectrum (PAS). METHODS: A prospective, descriptive observational study was conducted to evaluate a multimodal educational model during three standardized workshops held in Bolivia and Peru between January and August 2023. The educational strategy combined flipped-classroom preparation, simulation-based training, interactive theoretical discussions, live ultrasound and surgical sessions, and follow-up mentorship. A total of 290 participants were enrolled, and 175 practicing obstetricians who completed all three surveys (precourse, immediate postcourse, and 6-month follow-up) were included in the analysis. Surveys assessed participants' prior exposure to PAS, perceived usefulness of each educational component, and implementation of learned techniques. RESULTS: Before the workshops, most participants had prior exposure to PAS but limited experience with uterine-sparing procedures. Following the workshop, participants rated the overall clarity and usefulness of simulation and theoretical sessions around an 8 out of 10 and the value of integrating live surgery as a 9 out of 10. At 6-month follow-up, between 16% and 52% reported having performed at least one technique taught during the workshop. All participants would recommend the course to colleagues. Nearly 30% maintained contact with instructors for diagnostic or surgical support. CONCLUSION: A multimodal educational model combining theory, simulation, and hands-on experience is well received by obstetricians and gynecologists and facilitates the integration of new surgical skills into clinical practice, supporting individualized management of PAS.
