Placement on the kidney transplant waitlist is more likely to occur at dialysis facilities rated high for quality care by the Center for Medicare & Medicaid Services, a new study finds.
Of 5869 dialysis facilities in the United States in 2017, 132 (2.2%) received 1 star, 436 (7.4%) received 2 stars, 2047 (34.9%) received 3 stars, 1660 (28.3%) received 4 stars, and 1594 (27.2%) received 5 stars for quality. The star ratings were based on measures of mortality, hospitalization, dialysis adequacy, vascular access, blood transfusion, and hypercalcemia.
Compared with 1-star dialysis facilities, 4- or 5-star dialysis facilities had significant 42% and 47% increased odds of waitlisting patients for kidney transplantation within a year of dialysis initiation, Joel T. Adler, MD, MPH, of Brigham and Women’s Hospital in Boston, Massachusetts, and colleagues reported in JAMA Network Open. Most 1- and 2-star facilities were located in urban areas and served a higher percentage of minorities. As the patient-to-nurse and patient-to-social worker ratios increased, the odds of waitlist placement decreased (5% and 1%, respectively, per 10-patient increment).
Patients receiving home dialysis and peritoneal dialysis had 1.5- and 2.2-fold increased odds of waitlist placement in the first year, compared with patients receiving in-center hemodialysis, the investigators reported. Compared with those at nonprofit and urban facilities, patients at for-profit and rural facilities had significant 22% and 37% decreased odds of early waitlisting, respectively. Large chain facilities had significant 4% decreased odds of placing patients within the first dialysis year compared with independent chains.
Patients informed of transplantation had significant 2.3-fold increased odds of waitlist placement within the first dialysis year, according to the investigators. Men had significant 32% increased odds of waitlisting compared with women. Black patients had 26% decreased odds of early placement compared with White patients.
Each 1 year increase in age was associated with significant 5% decreased odds of waitlist placement. Employment was associated with significant 2.4-fold increased odds of early waitlisting. Retirement was associated with significant 6% decreased odds.
Dr Adler’s team stated that “the wide variability in the proportion of waitlisted patients suggests that this may be an important target for a quality measure. In the context of changing payment models that are intended to improve ESKD care, attention to the association between dialysis facility quality and transplantation should guide future policy.”
