Background
The ESRD Treatment Choices (ETC) Model - implemented in January 2021 - randomized dialysis providers and nephrologists in 30% of US hospital referral regions to receive financial incentives based on rates of home dialysis and access to transplantation. The model also included a health equity incentive to reduce disparities among dually eligible Medicare and Medicaid patients, who are low socioeconomic status and disproportionately Black and Hispanic. In this study, we used data from the US transplant registry to describe the early impact of the model on transplant waitlisting.
Methods
We assembled a cohort of adult Medicare beneficiaries on dialysis who were waitlisted for a kidney transplant between Jan 1, 2017 and Sept 30, 2021. The cohort was divided into the intervention and control arms of the ETC model. Kidney transplant waitlisting between groups was evaluated using an interrupted time series design. We used piecewise linear regression to compare slope changes in waitlist additions between the intervention and control arms for the overall population, Black, and Hispanic transplant candidates.
Results
Following implementation of the ETC model, there were 4975 waitlist additions in the intervention arm and 8438 additions in the control arm. Post-ETC model, we found no significant difference in kidney transplant waitlist additions between the intervention and control arm for the overall cohort (Figure 1 slope difference 0.87/month p-value 0.068), Black (slope difference 0.25/month, p-value 0.23), and Hispanic transplant candidates (slope difference 0.04/month, p-value 0.75).
Conclusion
In the first 9-months following implementation of the ETC model, we did not detect an increase in new kidney transplant waitlist additions overall or among racial and ethnic minorities. Longer-term follow-up is required to determine if the ETC model incentives are sufficient to overcome barriers to transplant waitlisting.
