The Relationship Between Change in Employment Status, Insurance Coverage, and Graft Failure or Death After Kidney Transplant

Abstract

Introduction: Early change of insurance coverage after kidney transplantation may be associated with worse graft outcomes. We examine how return to employment moderates the hazard of graft failure associated with exit from Medicare within 36 months after transplantation. Design: Patients undergoing kidney transplantation covered by Medicare between January 2005 and December 2016 were identified in the United Network for Organ Sharing (UNOS) database. A composite outcome of graft failure or death was analyzed across four groups: (1) no change in coverage within the first 3 years post-transplant, and no return to work (2) no change in coverage, return to work (3) change in coverage, no return to work (4) change in coverage, return to work. Results: The sample included 46 120 patients; 28% changed insurance coverage from Medicare posttransplant. Among patients who returned to work (36%), change in coverage from Medicare to other insurance was associated with lower hazard of death or graft failure (hazard ratio: 0.93; 95% confidence interval: 0.87, 0.99; P = 0.030). Conclusions: Exit from Medicare was associated with patient and graft survival greater than 3 years after transplant, depending on return to work. Among patients returning to work, changes in insurance from Medicare to private coverage were associated with favorable outcomes.
