Psychosocial variables are associated with being wait-listed, but not with receiving a kidney transplant in the Dialysis Outcomes and Practice Patterns Study (DOPPS)

Abstract

Psychosocial factors are associated with clinical outcomes in patients with end-stage renal disease. It is not known if self-reported depression and quality of life influence the likelihood of being wait-listed and receiving a transplant. Prevalent cross section of 18- to 65-year-old hemodialysis (HD) patients in the USA (N = 2033) and seven European countries (N = 4350) from the Dialysis Outcomes and Practice Patterns Study phase II and III was analyzed. Wait-listed patients (N = 1838) were followed until kidney transplantation. Self-reported depressive symptoms were assessed by the Center for Epidemiologic Studies-Depression scale, 10-item version (CES-D) and health-related quality of life (HR-QoL) by the Kidney Disease Quality of Life Short Form 12 scale Physical Component Score (PCS). At study entry, 27% (USA) to 53% (UK) of patients were wait-listed in participating countries. Variables associated with lower odds of being on the waiting list included worse HR-QoL, more severe depressive symptoms, older age, fewer years of education, lower serum albumin, lower hemoglobin, shorter time on dialysis and presence of multiple comorbid conditions. Among wait-listed patients, significantly lower transplantation rates were seen for females, blacks, patients having prior transplantation and multiple comorbid conditions but not PCS or CES-D. Fewer depressive symptoms and better HR-QoL are associated with being on the waiting list in prevalent HD patients but not with receiving a kidney transplant among wait-listed dialysis patients. Regular assessment of subjective well-being may help identify patients with reduced access to wait-listing and kidney transplantation.
