Obstetrics and gynecology residents’ satisfaction and self-confidence after an anal sphincter injury simulation-based workshop in Indonesia: a pre- and post-intervention comparison study

Abstract

Purpose: Obstetric anal sphincter injury (OASI) is one of the most common complication during delivery. Simulation models using manikin can be used as an effective medical learning method to improve students’ abilities before meeting patients. It aimed to describe the development of anal sphincter injury model and assess the resident satisfaction and self-confidence after perineal repair workshop with anal sphincter injury simulator in Indonesia.Methods: This was cross-sectional study with evaluation of outcome before and after workshop. We created silicone-latex simulation anal sphincter injury model. Then, we validated this simulation and made it as simulation model for workshop. We asked residents’ satisfaction repairing anal sphincter injury using simulation model and residents’ self-confidence when practicing the anal sphincter injury repair. Results: All residents felt the simulation-based workshop was valuable (100%). Most of score for similarity simulation model were good (about 8). The self-assessment of confidence was measured prior to the workshop and after the workshop. The overall self-confidence was increased significantly after workshop in procedure identification external sphincter ani (EAS) (P=0.031), suturing anal mucosa (P=0.001), suturing internal sphincter ani (P=0.001), suturing external sphincter ani (EAS) (P <0.001), evaluation of sphincter ani tone (P=0.016). Conclusion: Anal sphincter injury simulator improves the self-confidence of residents in procedure identification external sphincter ani (EAS), suturing anal mucosa, suturing internal sphincter ani, suturing external sphincter ani (EAS) and evaluation of sphincter ani tone.
