Effect of electronic and hybrid learning modalities for manual perineal support on incidence of obstetric anal sphincter injuries

Introduction: Obstetric anal sphincter injuries (OASIS) are the leading cause of female anal incontinence. Bimanual perineal support technique (bPST) help prevent OASIS. The study aims to test the effect of two different modalities for learning (bPST) on the incidence of OASIS. Methods: A quality-improvement-interventional study conducted in two hospitals between 1st June 2015 and 31st December 2016. A total of 1694 women were enrolled; all delivered vaginally at ≥24 gestational-weeks or with birthweight ≥1000gm.
