Hospice Referral Rate Disparities of American Indian/Alaska Native Kidney Transplant Recipients with End-Stage Kidney Disease: A Retrospective Cohort Analysis

Abstract

Introduction

American Indian/Alaska Native (AI/AN) persons disproportionately suffer from end-stage kidney disease caused by diabetes (ESKD-D). Kidney transplant is the most desirable option to treating ESKD-D, but remains unattainable for many AI/AN persons, especially in rural South Dakota (SD). Additionally, palliative and hospice care options for AI/AN with any serious illness in SD are largely inaccessible. Moreover, receiving kidney transplant potentially affects hospice referral because of the desire to prolong transplant function. Therefore, the purpose of this study was to compare hospice use rates among AI/AN and non-Hispanic White (NHW) persons with ESKD-D prior to death and determine if differences in referral rates are present for those with and without a prior kidney transplant.

Methods

Retrospective cohort analysis of United States Renal Data System data from 2000-2021. Data for persons with hospice care, transplant status, place of death, and race were analyzed using chi-squared tests with Yates’ continuity correction and the Cochran-Mantel-Haenszel test.

Results

AI/AN persons with ESKD-D were less likely to receive hospice care prior to death compared to NHW persons in both transplant (P < 0.001) and non-transplant (P < 0.001) groups. When comparing transplant and non-transplant groups by hospice use, persons with no previous transplant were more likely to receive hospice care prior to death (P < 0.001).

Conclusion

These results confirm the assumptions of significant differences in hospice care use among AI/AN vs NHW who have ESKD-D, including differences between those with a prior transplant. There is a need to expand palliative/hospice care services for persons with a prior kidney transplant.
