The ASCENT (Allocation System Changes for Equity in Kidney Transplantation) Study: A Randomized Effectiveness-Implementation Study to Improve Kidney Transplant Waitlisting and Reduce Racial Disparity

The United Network for Organ Sharing (UNOS) implemented a new Kidney Allocation System (KAS) in December 2014 that is expected to substantially reduce racial disparities in kidney transplantation among waitlisted patients. However, not all dialysis facility clinical providers and end-stage renal disease (ESRD) patients are aware of how the policy change could improve access to transplantation. Methods: We describe the ASCENT (Allocation System Changes for Equity in Kidney Transplantation) study, a randomized, controlled effectiveness-implementation study designed to test the effectiveness of a multicomponent intervention to improve access to the early steps of kidney transplantation among dialysis facilities across the United States. The multicomponent intervention consists of an educational webinar for dialysis medical directors, an educational video for patients and an educational video for dialysis staff, and a dialysis facility−specific transplantation performance feedback report. Materials will be developed by a multidisciplinary dissemination advisory board and will undergo formative testing in dialysis facilities across the United States. Results: This study is estimated to enroll ∼600 US dialysis facilities with low waitlisting in all 18 ESRD networks. The co-primary outcomes include change in waitlisting and waitlist disparity at 1 year; secondary outcomes include changes in facility medical director knowledge about KAS, staff training regarding KAS, patient education regarding transplantation, and the intent of the medical director to refer patients for transplantation evaluation. Discussion: The results from the ASCENT study will demonstrate the feasibility and effectiveness of a multicomponent intervention designed to increase access to the deceased donor kidney waitlist and to reduce racial disparities in waitlisting.
