Original InvestigationRacial differences in survival in an urban peritoneal dialysis program

Methods
From January 1, 1987 to September 30, 1997, 527 incident patients (356 black, 110 white, 53 Hispanic, and 8 Asian) entered the end-stage renal disease program at Rush-Presbyterian-St. Lukes Medical Center. A patient's dialysis modality was defined by the therapy they were on by the third month on chronic dialysis. A total of 294 (56%) patients were treated in our in-center hemodialysis program. The remaining 233 (44%) patients were treated with continuous ambulatory PD and form the basis of
Results
Two-hundred thirty-three patients, 44% of all incident dialysis patients, were treated with PD during the study period. Of the patients treated with PD, 142 (61%) were black, 62 (27%) white, and 29 (12%) categorized as other (24 Hispanic and 5 Asian). Baseline clinical, comorbid conditions, as well as laboratory and adequacy information for all patients are shown in Tables 1 to 3. Racial differences in the baseline characteristics were evaluated for black and white patients. Black patients were
Discussion
During the 10-year period of evaluation a large proportion of patients (44%) incident to our dialysis program chose to be treated with PD and of those, 61% were black. Using an intent-to-treat analysis, adjusting for baseline clinical, biochemical, and adequacy parameters, we found age, CAD, serum albumin, and race to be predictive of patient survival in our PD patients. The risk of mortality for white patients was 2.4 times that of black patients. This significant effect of race on patient
