Background
Living donor kidney transplant (LDKT) offers a life-saving option for patients with end stage kidney disease, reducing wait times compared to deceased donor transplants. However, the characteristics of candidates that wait a shorter period compared to those waiting longer is unclear. We stratified the cohort by duration of wait times for a LDKT to analyze characteristics.
Methods
We included adult LDKT recipients at the University of Pennsylvania between 1/1/2015 and 11/30/2023. The wait time for a LDKT was defined as the time from the date of waitlisting to time of transplant. Patient characteristics were analyzed based on wait times of <1 year, 1-2 years, and >2 years. Pertinent factors determining wait times for a well-matched LDKT offer were presented in a multidimensional heatmap.
Results
Candidates receiving directed donor LDKT experienced the shortest wait times across all height and blood type categories, whereas end-chain LDKT recipients had the longest wait times. Non-White candidates were more likely to wait >2 years. Most White candidates received LDKT within 1-2 years. Candidates with blood type B had longer wait times.
Conclusion
Blood type and the source of LDKT impacted wait times the most. Minorities waited longer for a LDKT, highlighting disparities in access to LDKT. Future studies should explore mechanisms driving these disparities.
