	abstract = {BACKGROUND: Blood type AB kidney transplant candidates have the shortest waiting times, yet the current allocation system allows allocation of type A donor kidneys to type AB recipients. STUDY DESIGN: United Network for Organ Sharing/Organ Procurement and Transplantation Network data between 1995 and 2004, retrospective observational study. SETTING \& PARTICIPANTS: 189,773 candidates listed for kidney-only transplant; 93,604 kidneys transplanted, 15,580 kidneys discarded. PREDICTOR: Blood type and demographic/clinical variables. OUTCOMES \& MEASUREMENTS: The extent of disparities in waiting times and concurrent differences in recovery, discard, live donor, and deceased donor transplant rates. RESULTS: Blood type O, A, B, and AB candidates constituted 48\%, 34\%, 14\%, and 4\% of the list, respectively. Live donor transplant rates were lowest for type AB candidates (13.4\% vs 15.5\%, 16.8\%, and 15.2\%; P < 0.001). On multivariate analysis, type AB candidates had a 1.5-fold greater chance of receiving deceased donor kidney transplants than blood group A candidates (95\% CI, 1.45-1.55). Recovery rates of type AB kidneys were similar to those for other blood types, whereas discard rates of type AB kidneys were significantly higher (adjusted OR [aOR], 1.71; 95\% CI, 1.56-1.89) for both expanded criteria (aOR, 1.78; 95\% CI, 1.52-2.09) and standard criteria donors (aOR, 1.67; 95\% CI, 1.48-1.89). LIMITATIONS: Observational data. Potential confounding from unmeasured covariates. CONCLUSION: Allocation of type A kidneys to type AB recipients not only increases disparities in waiting times between these 2 groups; but concurrent with the shorter waiting times for type AB candidates, there is suboptimal use of type AB deceased donor and living donor kidneys.},
