BLACK adults may have significantly lower access to both deceased donor and live donor kidney transplants compared to White adults, according to a presentation at the American Transplant Congress. “Despite ongoing efforts to increase kidney transplantation access among disadvantaged communities, disparities exist,” commented an author on the research.
The research, utilizing data from the Scientific Registry of Transplant Recipients, evaluated 143,914 non-Hispanic Black and non-Hispanic White patients listed for transplant between 2000 and 2016. The study aimed to identify segregation and environmental factors affecting transplant access.
Researchers gathered ZIP code-level data on annualized particulate matter (PM2.5) and matched it to each candidate’s ZIP code and listing year. They also combined social and environmental injustice levels, defined by high PM2.5 and segregation scores, to examine their impact on transplant outcomes.
Findings revealed that Black candidates were more likely to reside in neighbourhoods with high levels of both PM2.5 and segregation (53.2% vs. 46.8%) compared to White candidates. Those in high PM2.5 and segregated areas had lower access to deceased donor and living donor kidney transplants compared to White candidates in areas with lower PM2.5 and segregation.
“Targeted initiatives are essential to address the synergistic impact of air pollution and segregation on access to kidney transplants,” the team emphasized. She suggested that national measures could include reducing vehicle traffic, improving the built environment, and addressing socioeconomic inequities.
This study highlighted the ongoing challenges and underscores the need for strategic initiatives to eliminate disparities in kidney transplant access among disadvantaged communities. The research team emphasised the need for community outreach, enhanced support networks, and cultural practices.
