Objectives: Given the shortage of kidney donations relative to the ever-increasing demand, there is an ongoing need to utilize available donor organs efficiently and fairly. The purpose of the deceased donor Kidney Allocation System is to optimize and equalize organ access for candidates nationwide. We investigated the outcomes of kidney transplant cases before and after the new allocation placement in March 2021 and the effect of the new allocation system on these outcomes.
Materials and methods: We retrospectively reviewed the medical records of the recipients. Outcomes in recipients of renal allografts were compared before and after the changes in March 2021 to the Kidney Allocation System.
Results: There were 333 (73.7%) renal allografts transplanted before the 2021 new allocation, and 119 (26.3%) recipients received their renal allografts after the new allocation. The rate of delayed graft function was 33.3% in the preallocation group and 38.65% in the postallocation group (P = .29). The rate for patient readmission within 30 days was compared between the groups and did not show a statistically significant difference (37.8% vs 39.5%; P = .75). The 1-year graft survival rate was 97.5% in the postallocation group and 95.5% in the preallocation group (P = .526). The 1-year patient survival rate was 98.3% in the postallocation group and 95.8% in the preallocation group (P = .499).
Conclusions: This study provides reassurance in finding no statistically significant differences between patient outcomes before and after the implementation of the March 2021 change to the Kidney Allocation System. However, the new allocation measures would help for a more equal distribution of the kidneys.
