Background
Addressing social determinants of health is integral to kidney transplant management, although focus has only recently shifted to neighborhood-level effects. Using data from the Scientific Registry of Transplant Recipients, we describe the association between neighborhood socioeconomic deprivation and graft loss in pediatric kidney transplant recipients.
Methods
US recipients <18 years of age at time of listing who underwent kidney transplantation January 1st, 2010, to May 31st, 2022 (n=9,719) were included. Neighborhood deprivation was calculated using patient ZIP codes at time of listing and the Material Community Deprivation Index (MCDI), ranging from 0 (least deprived) to 1 (most deprived). Recipients were stratified into quintiles (Q). Kaplan-Meier and multivariable Cox proportional hazard estimates were calculated.
Results
The median MCDI for the most deprived neighborhoods (Q5) was 0.53 [IQR: 0.47, 0.84] compared to 0.23 [IQR: 0.06, 0.27] in the least deprived (Q1). Black and Hispanic patients were over-represented in the most deprived neighborhoods. As neighborhood deprivation increased, dialysis duration and deceased donation increased, while preemptive transplantation decreased. Recipients living in the most deprived neighborhoods had a 1.67 times greater risk of graft loss compared to the least deprived (CI: 1.42, 1.98).
Conclusion
Pediatric kidney transplant recipients with the highest levels of neighborhood socioeconomic deprivation had a greater risk of graft loss. Increased focus should be placed on contextual effects of neighborhood environment to address health disparities in pediatric kidney transplantation.
