Obstetric Anal Sphincter Injury Care Bundle: A Quality Improvement Initiative

The objective was to implement an evidence-based peri-partum care bundle for women sustaining obstetric anal sphincter injuries and to evaluate compliance with recommendations for antibiotics use, repair in the operating room, and follow-up before and after implementation.

A total of 185 cases were identified. Seventy-five percent of women were nulliparous. Mean gestational age was 39 weeks. Pre- and post-intervention groups did not differ in age, BMI, race, parity, gestational age, comorbidities, birthweight, or delivery type. Ninety-eight cases were identified pre-implementation. Eighty-six (88%) had third-degree lacerations. Post-implementation, 87 cases were identified. Seventy (80%) had third-degree lacerations (p = 0.17). Recommended antibiotic-type use improved from 35% pre-implementation to 93% post-implementation (p < 0.001). Repair in the operating room was similar pre-implementation and post-implementation (16.0% vs 12.6%, p = 0.48). Post-partum follow-up within 2 weeks improved from 16.3% pre-implementation to 52.8% post-implementation and mean time to follow-up was shorter post-implementation than pre-implementation (18 vs 33 days; both p < 0.001).

Implementation of an evidence-based peri-partum care bundle resulted in standardization of care in accordance with established recommendations. Compliance with recommendations for surgical repair in the operating room remained unchanged.
