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

To evaluate the perceived educational value of a multimodal surgical training model designed to improve obstetricians' skills in managing placenta accreta spectrum (PAS).

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.

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.

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.
