Implication

Cohort study evaluated obstetric anal sphincter injury risk factors in women giving birth, highlighting key findings about amniotomy and instrumental delivery.

Key Points

Amniotomy was not found to increase the risk of obstetric anal sphincter injury, contrasting prior findings.
Annual incidence of obstetric anal sphincter injury remained stable at around 2% across 26349 analyzed births.
Retrospective cohort analysis used multivariate logistic regression to model risk factors for obstetric anal sphincter injury.
Instrumental delivery significantly increased the risk of obstetric anal sphincter injury, calling for revised clinical practices.
