Effect of external peer review on cesarean delivery rates: A statewide program

Abstract

To assess the effectiveness of a joint-specialty society and health department statewide peer-review program to reduce cesarean rates. Forty-five of the 165 hospitals with active delivery services were reviewed between 1989 and 1993. Differences in total and repeat cesarean rates and vaginal birth after cesarean (VBAC) rates were compared by hospital review status using Student t tests and linear regression for the years before and after completion of the program. Reviewed hospitals reduced their total cesarean rate by 3% and repeat cesarean rate by 0.7%, and increased their VBAC rate by 14.6% compared with nonreviewed hospitals, for which the respective reduction in rates was 1%, 0.6%, and 12.7%. Statistically, there was no difference between reviewed and nonreviewed hospitals in terms of rate changes. This joint-specialty society and health department peer review had no apparent impact on cesarean rates.
