Rates of organ donor registration range from 20% to 60% throughout the United States. The purpose of this study was to examine sociogeographic differences in organ donor registration rates throughout Missouri to identify varying patterns The organ donor registration rate from each Department of Motor Vehicle office in Missouri was extracted from the National Organ Registration database, office locations were geocoded, and census tract level sociodemographic characteristics were extracted. Spatial regression analyses were conducted to identify relationships between location of DMV offices and census tract-level concentrated disadvantage. Census tract-level concentrated disadvantage (education attainment, poverty, single-headed households) had a significant negative relationship with organ donor registration rates. Yet, census tract-level African American/Black resident concentration was not significantly related to organ donor registration rates. These findings suggest that race-based interventions to recruit organ donors may no longer be necessary. Yet, identifying how characteristics of concentrated disadvantage may be more influential in determining organ donor registration. Gaining a better understanding of how individual decisions are made is integral in the context of increased life expectancy in conjunction with the complex management of chronic conditions.
