Comparison of Births by Provider, Place, and Payer in New Hampshire

Geospatial variation in caesarean delivery

Aim

The purpose of this study was to evaluate the variation in caesarean delivery rates across counties in Georgia and to determine whether county-level characteristics were associated with clusters.

Design

This was a retrospective, observational study.

Methods

Rates of primary and repeat caesarean by maternal county of residence were calculated for 2008 through 2012. Global Moran's I (Spatial Autocorrelation) was used to identify geographic clustering. Characteristics of high and low-rate counties were compared using student's t test and chi-squared test.

Results

Spatial analysis of both primary and repeat caesarean rate identified the presence of clusters (Moran's I = 0.375; p < .001). Counties in high-rate clusters had significantly lower access to midwives, more deliveries paid by Medicaid, higher proportion of births for women belonging to racial/ethnic minority groups and were more likely to be rural.

Obstetric Access and the Community Health Imperative for Rural Women

This study examined whether the closure of several inpatient obstetric units in rural New Hampshire affected birth outcomes. It is a secondary analysis of birth certificate data from 2005 through 2012 and includes 5881 births. There were no changes in perinatal outcomes. When examining outcomes based on distance travelled to place of birth, controlling for closures, women who traveled greater than 30 miles had fewer prenatal visits and lower birth weight and gestational age infants. Community services that provide prenatal care and/or home visiting are even more important when obstetric units are not available in the community.
