Impact of COVID-19 crisis on disparities in living kidney donation in the US

Purpose: The COVID-19 pandemic resulted in a dramatic decrease in living kidney donation (LKD) in the U.S. This study investigated the effect of the COVID crisis on characteristics of LKD recipients in the U.S. Methods: We used OPTN transplant and LKD data to compare proportions of LKD recipients' race, SES (neighborhood income), sex, dialysis status, age, and recipient/ donor sex match during 3 eras: Pre-COVID (1/1/20-3/12/20, n=1294);COVID Shutdown (3/13/20-5/9/20, n=173);and COVID Stabilization (5/10/20-11/15/20, n=2331;Table 1). Results: Contrary to our expectations, LKD recipients' race, neighborhood income, and dialysis status at transplant did not differ by era (Figure 1a-c;Table 2). We did, however, find a significant relationship between recipient sex and era, with a higher proportion of male recipients in the COVID Shutdown and COVID Stabilization eras than in the Pre-COVID era (Figure 1d). We found a related significant association between recipient/donor sex match and era, with a higher proportion of male-recipient/female-donor transplants and a lower proportion of female-recipient/ female-donor transplants in the COVID Shutdown and COVID Stabilization eras than in the Pre-COVID era (Figure 1e). There was a marginally significant relationship between recipient age at transplant and era, with a higher proportion of younger recipients in the COVID Shutdown era than in the Pre-COVID and COVID Stabilization eras (Figure 1f). Conclusions: While we did not find expected differences in areas of current disparities such as LKD recipient race or SES, we did find that the drop in living donation caused by the COVID crisis exacerbated previously existing disparities in recipient sex and recipient/donor sex match, suggesting that COVID has not had an equal effect on all candidates.
