Effective training program for antenatal diagnosis of placenta accreta spectrum disorder

Abstract

AbstractObjectiveTo develop and evaluate a training program for diagnosing placenta accreta spectrum (PAS) disorder in obstetrics/gynecology and radiology residents.MethodsThis 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.ResultsTwenty‐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.ConclusionAn antenatal diagnosis of PAS training program can be effective as a residency training program, considering the globally rising cesarean delivery rates.
