Population Health, Ethnicity and Rate of Living Donor Kidney Transplantation

Background Living donor kidney transplantation has declined in the United States since 2004, but the relationship between population characteristics and rate of living donation is unknown. The goal of our study was to use data on general population health and socioeconomic status to investigate the association with living donation. Methods This cross-sectional, ecological study used population health and socioeconomic status data from the CDC Behavioral Risk Factor Surveillance System (BRFSS) to investigate the association with living donation. Transplant centers performing ≥ 10 kidney transplants reported to the Scientific Registry of Transplant Recipients in 2015 were included. Center rate of living donation was defined as the proportion of all kidney transplants performed at a center that were from living donors. Results In a linear mixed effects model, a composite index of health and socioeconomic status factors was negatively associated with living donation, with a rate of living donation that was on average 7.3 percentage points lower among centers in areas with more comorbid disease and poorer socioeconomic status (95% CI: -12.2 to -2.3, p=0.004). Transplant centers in areas with higher prevalence of minorities had a rate of living donation that was 7.1 percentage points lower than centers with fewer minorities (95% CI: -11.8 to -2.3, p=0.004). Conclusions Center level variation in living donation was associated with population characteristics and minority prevalence. Further examination of these factors in the context of patient and center-level barriers to living donation is warranted. Corresponding Author: Jayme E.
