Abstract T P128: Ethnicity and the Availability of Rehabilitation Facilities in the Brain Attack Surveillance in Corpus Christi Project

Abstract

Background: Mexican Americans (MAs) have worse stroke outcomes than non-Hispanic whites (NHWs). One explanation may be ethnic differences in post-stroke rehabilitation; despite its effectiveness, non-clinical factors such as geographic availability may influence use of certain rehabilitation venues. We investigated ethnic differences in availability of stroke rehabilitation venues in a bi-ethnic community. Methods: Stroke survivors were identified through the population-based Brain Attack Surveillance in Corpus Christi (BASIC) Project from 2011-2013 in Nueces County, a bi-ethnic, mostly urban community in southeast Texas with a population of 340,000. Addresses of inpatient rehabilitation facilities (IRFs) and skilled nursing facilities (SNFs) providing stroke rehabilitation were identified by phone/internet and geocoded. Availability was defined as distance to and supply of each type of venue in relation to the survivor’s home. Supply was calculated as the count of each type of venue within a given radius (defined as the 90th percentile of distribution of distances to reflect a reasonable market area). Associations between availability and ethnicity were modeled using linear regression adjusted for census tract-level median household income, proportion <65 years, and population density as obtained from the 2012 American Community Survey. Results: A total of 942 survivors were eligible (62% MA, 38% NHW); 3 IRFs and 21 SNFs were identified. The average distances from the survivors’ homes to an IRF or SNF were 5 miles (SD=6) and 2 miles (SD=3), respectively. Supply was calculated within radii of 16 miles for IRFs and 4 miles for SNFs. The average count of rehabilitation venues within these radii was 2.6 IRFs (SD=0.9) and 7.9 SNFs (SD=4.7). There were no ethnic differences in the distance or supply of IRFs; however, MAs were on average 1 mile (CI:0.6-1.5) closer to and had 0.8 (CI:0.2,1.3) more SNFs within the radius than NHWs. Conclusions: Availability of rehabilitation venues was high for both ethnic groups; however, MAs have greater availability of SNFs compared to NHWs. Additional study is necessary to understand how the availability and quality of services within rehabilitation venues impact post-stroke rehabilitation among MA stroke survivors.
