Abstract
INTRODUCTION: Obstetric anal sphincter injuries (OASIS) have been reported in up to 35% of vaginal deliveries; thus, understanding these injuries is a critical part of obstetrics and gynecology training. Formal educational programs with incorporated simulation training can have an advantageous effect, particularly when provided as part of residency education. This project seeks to evaluate the positive effect of departmental resident education related to OASIS, on confidence and knowledge of obstetrics and gynecology residents at Wake Forest University. METHODS: A structured OASIS curriculum was developed by the urogynecology program, including 2 hours of didactic lecture followed by stepwise simulation with swine models to demonstrate and practice anatomic repair techniques. Participants completed pre- and post-class surveys including skill confidence assessments via Likert scale (range 1–10), and standardized knowledge assessments adapted from ACOG Obstetric Laceration Repair Module, along with educational experience reports. These items were scored and analyzed. RESULTS: In August 2022, 16 residents (4 per residency year) participated. Prior to education, mean confidence level with techniques was 4.2 among all areas (range 1.6–7.4), with mean knowledge assessment score 64% (range 33–100%). Post-education, confidence improved across several domains including effectively applying perineal support (7.3–7.9), identifying lacerations and performing rectal examinations (6.1–8.0), and OASIS repair (1.9–5.4) (P<.05). Knowledge assessment scores remained similar, at 70% (P>.05). In qualitative analysis, all individuals reported beneficial aspects of the program. CONCLUSION: Introduction of an OASIS curriculum including repair simulation utilizing an animal model, increased resident skill confidence. Future research will investigate longitudinal data to improve outcomes.
