Brief Summary
The purpose of the current study is to test a systems-level approach to disseminate a multicomponent, multilevel intervention consisting of educational materials about transplantation and the new kidney allocation system targeting dialysis facility medical directors, staff, and patients. Roughly 750 dialysis facilities in up to 18 End Stage Renal Disease Network regions across the United States will be randomized to receive intervention materials. The overall goal of the study is to extend the influence of the national allocation policy in reducing disparities in early steps in kidney transplant access.

Outcome Measures
Primary Outcomes (6)
Proportion of Incident Patients Waitlisted
The adjusted mean proportions of incident (new) patients waitlisted for kidney transplantation at study dialysis facilities, at the baseline and post-intervention time periods, were calculated. Incident patients are those who initiated dialysis treatment at study facilities during one of the study time periods. Mean proportions were adjusted for time and facility-level random effects.
Baseline (the twelve month period prior to the intervention), Post-intervention (the twelve month period after the intervention)
Proportion of Black and White Incident Patients Waitlisted
The adjusted mean proportions of Black versus White incident patients waitlisted for kidney transplantation at study dialysis facilities, at the baseline and post-intervention follow-up assessments, were calculated. Mean proportions were adjusted for time and facility-level random effects.
Baseline (the twelve month period prior to the intervention), Post-intervention (the twelve month period after the intervention)
Proportion of Prevalent Patients Waitlisted During the Baseline Period
The adjusted mean proportions of prevalent patients waitlisted for kidney transplantation at study dialysis facilities during the baseline time period were calculated. Mean proportions were adjusted for time and facility-level random effects.
Baseline (the twelve month period prior to the intervention)
Proportion of Prevalent Patients Waitlisted During the Post-Intervention Time Period
The adjusted mean proportions of prevalent patients waitlisted for kidney transplantation at study dialysis facilities during the post-intervention period were calculated. Mean proportions were adjusted for time and facility-level random effects.
Post-intervention (the twelve month period after the intervention)
Proportion of Black and White Prevalent Patients Waitlisted During the Baseline Period
Waitlisting disparity is assessed as the adjusted mean proportion of Black versus White prevalent patients waitlisted for kidney transplantation at study dialysis facilities during the baseline time period. Mean proportions were adjusted for time and facility-level random effects.
Baseline (the twelve month period prior to the intervention)
Proportion of Black and White Prevalent Patients Waitlisted During the Post-Intervention Time Period
Waitlisting disparity is assessed as the adjusted mean proportion of Black versus White prevalent patients waitlisted for kidney transplantation at study dialysis facilities during the post-intervention period. Mean proportions were adjusted for time and facility-level random effects.
Post-intervention (the twelve month period after the intervention)
Secondary Outcomes (4)

Percentage of Facilities With Increases or No Change/Decreases in Patient Education
Baseline, Immediately Post-intervention (3 months after the start of the intervention)
Percentage of Facilities With Increases or No Change/Decreases in Intent to Refer Patients for Kidney Transplantation
Immediately Post-intervention (3 months after the start of the intervention)
Study Arms (2)
Multi-Component Intervention
EXPERIMENTALEnd Stage Renal Disease (ESRD) facilities will receive feedback reports containing facility specific data, an educational webinar for dialysis facility medical directors and staff, and an educational video for patients and staff.
Standard Care + Pamphlet
ACTIVE COMPARATOREnd Stage Renal Disease (ESRD) facilities will conduct usual care and receive United Network for Organ Sharing (UNOS) educational pamphlets for staff.
Interventions
Medical directors will be provided performance feedback reports that are a summary of clinical performance of transplant and racial disparity performance over a period of time aimed at providing information to allow them to assess and adjust their transplant performance. The report will emphasize tailored facility-specific information on the mean time on dialysis for patients in that facility and transplant access performance measures, such as wait listing and transplantation, including the magnitude of racial disparity, detailing when a facility is performing below the national or regional average.
Dialysis facility staff will watch a \~10 minute educational video that describes the role of dialysis staff in improving transplant access, the new kidney allocation policy, and how the new policy impacts minority patients and those on dialysis for a substantial period of time.
Dialysis facilities will receive a \~10 minute educational video targeted to dialysis patients to explain the transplant process and allocation policy.
Education for medical directors and facility staff about the kidney allocation policy will be discussed in a webinar and information will be hosted on a website for participants to access. The seminar will be roughly 45 minutes, and continuing medical education (CME) credits will be offered.
Dialysis facilities will conduct standard or usual care and education regarding transplantation.
Dialysis facility staff will be provided an educational pamphlet detailing the changes in the new kidney allocation policy .
Eligibility Criteria
You may qualify if:
- Dialysis facilities with at least 25 patients composed of at least 10% African American and 10% Caucasian
You may not qualify if:
- Dialysis facilities with wait listing rates above the national tertile
