Abstract: Suboptimal dialysis initiation is associated with adverse patient outcomes. Whether it is also associated with access to downstream transplant care is unknown. Adults initiating dialysis treatment for kidney failure in the Southeast U.S., from 1/1/2015 to 12/31/2019 were identified from the United States Renal Data System, linked to the Early Steps to Transplant Access Registry, and followed through 12/31/2021. The primary exposure was pre-dialysis care and categorized as highly, moderately, minimally, or non-optimal based on presence of nephrology care, dialysis type (in-center or home hemodialysis, peritoneal dialysis), and vascular access vs. catheter. Primary outcomes were referral to a transplant center within 12-months of dialysis initiation and evaluation start at a transplant center within 6 months of first referral. Multivariable competing risk models quantified the association between pre-dialysis care context and referral and evaluation. Among 49,057 patients initiating dialysis, 28.8%, 15.5%, 31.0%, and 24.8% are highly, moderately, minimally, and non-optimal start, respectively. Patients initiating dialysis in moderately, minimally, and non-optimal ways are 28% (adjusted hazard ratio: 0.72, [95% CI: 0.69 − 0.72], 31% (0.69, [0.66 − 0.71], and 57% (0.43, [0.41 − 0.44]) less likely to be referred as compared with highly optimal starters. Those who had a non-optimal start are also 37% less likely to start the evaluation after being referred (0.63, [0.59 − 0.66]) as compared with highly optimal dialysis starters, while all other groups have a similar likelihood. More than half of U.S. adults with kidney failure initiate dialysis in a minimal or non-optimal way leading to reduced likelihood of transplant referral and evaluation. In this study, we examined if readiness to start dialysis among adults with kidney failure was associated with reduced access to downstream transplant care. Using a multi-state registry of patients initiating dialysis in the Southeast U.S., we found that more than half of adults initiated dialysis in a sub-optimal way as defined by dialysis type, nephrology care, and vascular access. These individuals were signficantly less likely to be referred or evaluated for transplant as compared with those starting dialysis in a highly optimal way. Our findings highlight the importance of early identification and intervention for adults progressing to kidney failure to ensure optimal readiness and enhance access to lifesaving transplant. Harding et al. investigate the relationship between dialysis preparedness and access to transplant care. Their findings suggest that more than half of U.S. adults initiate dialysis in a sub-optimal way with a lower likelihood of then being referred to and evaluated at a transplant center, ultimately reducing access to lifesaving transplant.
