Abstract

To develop and evaluate a training program for diagnosing placenta accreta spectrum (PAS) disorder in obstetrics/gynecology and radiology residents. This single-center prospective study was based on 177 ultrasound images of pathologically confirmed PAS extracted from 534 cases of placenta previa suspicious for PAS. First- to third-year residents were evaluated before training to assess experience and ability to diagnose PAS. They attended a principal lecture followed by weekly self-study exercises over 5 weeks. Post-course tests evaluated the efficacy of the training program for improving diagnosis of PAS after the program. Twenty-three (38.3%) obstetrics/gynecology and 37 (61.7%) radiology residents were trained. Before the training program, 98.3% reported minimal experience and 100% low confidence to correctly diagnose PAS. During the program, the overall accuracy of all participants in diagnosing PAS increased from 71.3% before to 95.2% after training (P < 0.001). Regression analyses showed that ability to diagnose PAS increased 2.52-fold (P < 0.001) following the program. The retention of knowledge at 1, 3, and 6 months posttest was 84.7%, 87.5%, and 87.7%, respectively. An antenatal diagnosis of PAS training program can be effective as a residency training program, considering the globally rising cesarean delivery rates. © 2023 International Federation of Gynecology and Obstetrics.
