Abstract
BACKGROUND

Kidney transplantation (KT) is essential for end-stage renal disease, significantly improving survival and quality of life. Yet, in pediatric renal disease management, minority children face poorer dialysis outcomes and reduced access to transplantation.

AIM

To identify and understand these differences in the pediatric population.

METHODS

Using ICD-10 codes, we queried the 2022 Health Care Cost and Use Project Kid’s Inpatient Database for admissions with a primary or secondary diagnosis of severe chronic kidney disease (sCKD), namely stages 4 and 5, or a KT procedure. Patient demographics, insurance types, and hospital stay metrics were assessed through statistical analyses including Wilcoxon Rank Sum, χ2, and logistic regression.

RESULTS

A total of 636 hospital admissions related to KT surgery and 3733 hospital admissions with sCKD as the primary diagnosis were identified. In both the KT and sCKD cohorts, most patients were White (42.6% vs 36.6%), male (59.8% in both groups), aged 12-18 years (57.9% vs 50.3%), and insured by Medicaid (35.7% vs 43.0%). KT and sCKD hospitalizations were uncommon among infants aged 0-1 year (1.6% and 9.9%, respectively). Analysis of income quartiles based on patients’ residential zip codes demonstrated no significant differences between those who underwent KT and those with sCKD without transplant. Although mortality rates did not differ statistically between groups, a numerical difference was observed, with higher mortality in the sCKD cohort compared to the KT cohort (16 deaths vs 4 deaths).

After adjusting for socioeconomic and geographic factors, Black race was independently associated with lower odds of undergoing KT (adjusted odds ratio 0.69; 95% confidence interval: 0.53-0.89).

CONCLUSION

Pediatric KT recipients were more likely to be male, White, and aged 12-18 years. Racial disparities persist, with ethnic minority groups-particularly Black patients-facing reduced access to KT. These findings underscore the necessity of implementing targeted interventions to promote equitable access to pediatric KT.

Keywords: Kidney transplant; Severe chronic kidney disease; Pediatric; Socio economic disparities; Transplant allocation

Core Tip: In this study, we found that black race is significantly associated with lower rates of kidney transplantation (KT) after controlling socioeconomic and geographic factors. Although studies have analyzed health care utilization and disparities in various pediatric renal diseases such as acute kidney injury, socioeconomic and demographic disparities have been poorly defined in the pediatric literature on KT. In this study, we excluded young adults 18-21 who may have increased difficulty with access to care as they transition from pediatric to adult care. Future prospective studies are needed to evaluate the complexity of disparities in pediatric KT access.
