Background
Approximately 15% of the 4 million annual U.S. births occur in rural hospitals.
Objective
To 1) measure differences in obstetric care in rural and urban hospitals and 2) examine whether trends over time differ by rural-urban hospital location
Research Design and Subjects
Retrospective analysis of hospital discharge records for all births in the 2002-2010 Nationwide Inpatient Sample, a 20% sample of U.S. hospitals (N=7,188,972 births; 6,316,743 in urban hospitals, 837,772 in rural hospitals).
Measures
Rates of low-risk cesarean (full-term, singleton, vertex pregnancies; no prior cesarean), vaginal birth after cesarean (VBAC), non-indicated cesarean, and non-indicated labor induction.
Results
In 2010, low-risk cesarean rates in rural and urban hospitals were 15.5% and 16.1%, respectively, and non-indicated cesarean rates were 16.9% and 17.8%. VBAC rates were 5.0% in rural and 10.0% in urban hospitals in 2010. Between 2002 and 2010, rates of low-risk cesarean and non-indicated cesarean increased, and VBAC rates decreased in both rural and urban hospitals. Non-indicated labor induction was less frequent in rural versus urban hospitals in 2002 (AOR=0.79 [0.78-0.81]), but increased more rapidly in rural hospitals from 2002-2010 (AOR=1.05 [1.05-1.06]). In 2010, 16.5% of rural births were induced without indication (12.0% of urban births).
Conclusions
From 2002-2010, cesarean rates rose and VBAC rates fell in both rural and urban hospitals. Non-indicated labor induction rates rose disproportionately faster in rural vs. urban settings. Tailored clinical and policy tools are needed to address differences between rural and urban hospitals.
