| Summary: | Background. Deceased-donor kidney discard rates vary by region, but it is unknown whether discard rates and transplant outcomes vary during the American Transplant Congress (ATC) each year.
Methods. Using national registry data, we determined rates of kidney discard, delayed graft function, graft failure, and mortality from December 31, 1999, through December 30, 2015, during ATC dates and compared these rates with those on the same days of the week during the 2 weeks before and after the ATC (non-ATC). We used multivariable regression to determine associations between ATC and these outcomes.
Results. From 7902 donors (1575 ATC; 6327 non-ATC), 12 588 recipients received kidney transplants (2455 ATC; 10 133 non-ATC), and 2666 kidneys were discarded (582 ATC; 2084 non-ATC). Kidneys were more often discarded during ATC (19% vs 17%, P = 0.006; adjusted odds ratio, 1.21; 95% confidence interval, 1.05-1.40). There were no significant differences in donor, transplant, or recipient characteristics by ATC/non-ATC dates or by ATC/non-ATC transplant dates for delayed graft function, graft failure, or mortality.
Conclusions. On the basis of a 21% increased odds of discard, the ATC itself may result in 5 additional kidney discards during this important conference every year, which suggests the need for innovative staffing or other logistic solutions during these planned meetings.
