BackgroundCompleting pre-transplant evaluations may be a greater barrier to renal transplantation for blacks with end-stage renal disease (ESRD) than for whites.ObjectiveTo determine whether social support networks facilitate completing the pre-transplant evaluation and reduce racial disparities in this aspect of care.Design, Setting, And ParticipantsWe surveyed 742 black and white ESRD patients in four regional networks 9 months after they initiated dialysis in 1996 and 1997. Patients reported instrumental support networks (number of friends or family to help with daily activities), emotional support networks (number of friends or family available for counsel on personal problems) and dialysis center support (support from dialysis center staff and patients). The completion of pre-transplant evaluations, including preoperative risk stratification and testing, was determined by medical record reviews.Outcome MeasurementComplete renal pre-transplant evaluations.ResultsCompared to patients with low levels of instrumental support, those with high levels were more likely to have complete evaluations (25% versus 46%, respectively, p < .001). In adjusted analyses, high levels of instrumental support were associated with higher rates of complete evaluations among black women (p < .05), white women (p < .05), and white men (p < .05), but not black men. Among black men, but not other groups, private insurance was a significant predictor of complete evaluations.ConclusionsInstrumental support networks may facilitate completing renal pre-transplant evaluations. Clinical interventions that supplement instrumental support should be evaluated to improve access to renal transplantation. Access to supplemental insurance may also promote complete evaluations for black patients.
