Abstract
OBJECTIVE
The aim of this study is to compare labor outcomes across race/ethnicity in women undergoing prostaglandin labor induction.
METHODS
Secondary analysis of misoprostol vaginal insert (MVI) trial, a double-blind, randomized, control trial of 1,308 patients comparing sustained release vaginal inserts containing dinoprostone 10 mg and misoprostol 50 mcg (MVI 50) or 100 mcg (MVI 100).
RESULTS
Achievement of active labor and induction failures were similar across race/ethnicity. Cesareans were performed less frequently in whites (29 %) and Hispanics (24.5 %) compared to blacks (32.7 %) (adjusted odds ratio (aOR) 0.87, 95 % confidence interval (CI) 0.47-0.97, p = 0.03 and aOR 0.86, 95 % CI 0.44-0.97, p = 0.03, respectively). When compared to blacks, whites were less likely to undergo cesarean for non-reassuring fetal heart rate tracing (aOR 0.41, 95 % CI 0.25-0.66, p = 0.0003), as were Hispanics (aOR 0.38, 95 % CI 0.22-0.65, p = 0.0004). Postpartum hemorrhage occurred more frequently in Hispanics (8.8 %) versus blacks (4.1 %) and whites (OR 2.27, 95 % CI 0.23-0.82, p = 0.02 and OR 3.69, 95 % CI 0.14-0.51, p < 0.0001, respectively). Birth weights of black infants were lower than whites (p < 0.0001) and Hispanics (p = 0.0003). Neonatal outcomes did not differ between groups.
CONCLUSION
Differences in labor induction outcomes with prostaglandin labor induction exist based on race/ethnicity. Blacks delivered smaller babies, were more likely to undergo cesarean, and have cesareans performed for non-reassuring fetal heart tracing compared to other groups. Hispanics were more likely to experience postpartum hemorrhage compared to the other races.
