Effects of shoulder dystocia training on the incidence of brachial plexus injury.

Objective: We sought to determine whether implementation of shoulder dystocia training reduces the incidence of obstetric brachial plexus injury (OBPI).

Study Design: After implementing training for maternity staff, the incidence of OBPI was compared between pretraining and posttraining periods using both univariate and multivariate analyses in deliveries complicated by shoulder dystocia.

Results: The overall incidence of OBPI in vaginal deliveries decreased from 0.
