ABSTRACT:

Objective

To evaluate the impact of a care bundle (antenatal information to women, manual perineal protection and mediolateral episiotomy when indicated) on obstetric anal sphincter injury (OASI) rates.

Design

Multicentre stepped-wedge cluster design.

Women with singleton live births between October 2016 and March 2018.

Methods

Stepwise region by region roll-out every 3 months starting January 2017. The four maternity units in a region started at the same time.
