A Quality Improvement Initiative to Increase the Frequency of Vaginal Delivery in Brazilian Hospitals.

OBJECTIVE

To evaluate a quality improvement (QI) initiative designed to increase the frequency of vaginal delivery in Brazilian hospitals.

METHODS

Twenty-eight hospitals enrolled in a 20-month (May 2015-December 2016) Breakthrough Series Collaborative that used QI methods to increase implementation of obstetric approaches with potential to increase the frequency of vaginal delivery. All hospitals contributed qualitative data for iterative redesign. Thirteen intervention hospitals with complete data contributed to an analysis of changes in vaginal delivery in a targeted population over time. Hospitals from the São Paulo region (five intervention and eight nonintervention) contributed to a comparator analysis of changes in vaginal delivery for all deliveries over time.

INTERVENTION

Most hospitals targeted low-risk pregnancies in primiparous women, delivered by hospital-employed obstetricians or admitted through emergency departments, and some included all pregnant women. The collaborative tested four interventions to increase vaginal delivery: 1) coalition building of stakeholders with the common purpose of ensuring "appropriate delivery," 2) empowering pregnant women to choose their preferred mode of delivery, 3) implementation of new care models favoring physiologic birth, and 4) improved information systems for continuous learning by health care providers.

RESULTS

For 119,378 targeted deliveries (36% of all deliveries) in 13 intervention hospitals, vaginal delivery increased from 21.5% in 2014 to 34.8% in 2016, a relative increase of 1.62 (95% CI 1.27-2.07, P<.001). In the comparator analysis, vaginal delivery for all deliveries in the five São Paulo intervention hospitals increased from 16.1% to 23% (RI 1.43, P<.001) and from 11.0% to 13.0% (relative rate ratio 1.18, P<.001) in the eight nonintervention São Paulo hospitals. The relative increase in vaginal delivery between the São Paulo intervention and nonintervention groups was 1.21 (95% CI 1.05-1.41, P=.01). The rate of maternal adverse events and neonatal intensive care unit admissions for newborns who weighed at least 2,500 g did not differ significantly during the observation period.

CONCLUSIONS

Key interventions implemented with QI methods were associated with increased vaginal delivery. This approach may help address the global cesarean delivery epidemic.
