County-level Analysis of Perinatal Health Indicators Within a Single Health System Catchment

Abstract

Background: Adverse perinatal health outcomes are disproportionally impacted in rural communities. Social determinants of health (SDoH) defined by nonclinical social, behavioral, and economic factors may impact up to 90% of health outcomes in rural communities. Objective: To evaluate county-level perinatal patterns in health outcomes, health behaviors, socioeconomic vulnerability, and healthcare providers across rural and non-rural Florida counties within a single health system catchment. Methods: Socioeconomic vulnerability metrics, digital connectivity, licensed provider metrics, and behavioral data and were obtained from Floridahealthcharts.com and the County Health Rankings. County-level birth and perinatal health outcome data were obtained from the Florida Department of Health. The University of Florida Health Perinatal Catchment Area (UFHPCA) was defined as all Florida counties where ≥5% of all infants were delivered at Shands Hospital in Alachua county between June 2011 and April 2017. County-level rurality was determined by Florida Statutes 288.0656 rurality designations. Results: The UFHPCA included three non-rural and ten rural counties that represented more than 64,000 deliveries over a 5-year 9-month period. We found that nearly 1 in 3 infants resided in a rural county (n=20,899), and 7 out of 13 counties did not have a licensed obstetrician gynecologist. Nine counties reported maternal death rates that were between 1 and 4-fold higher than the statewide rate, and rural counties generally reported neonatal mortality and preterm birth rates that were higher than the statewide averages. We found maternal smoking rates (range 6.8% – 24.8%) were above the statewide rate (6.2%) for all counties in the catchment. Except for Alachua county, breastfeeding initiation rates (range 54.9% - 81.4%) and access to household computing devices (range 72.8% - 86.4%) were below the statewide rate (82.9% and 87.9%, respectively). Finally, we found that childhood poverty rates (range 16.3% - 36.9%) in our catchment was above the statewide rate (18.5%), except for Suwanee and Columbia counties.Conclusions: The health burden of the UFHPCA is characterized by both rural and non-rural counties with increased maternal and neonatal death and preterm birth, as well as adverse health behaviors that include smoking during pregnancy and lower levels of breastfeeding.
