Ethnicity information was collected for all pediatric peritoneal dialysis patients from the End-Stage Renal Disease (ESRD) Clinical Performance Measures (CPM) Project for the period October 2004 through March 2005. Associations between intermediate outcomes and Hispanic ethnicity were determined. Thirty percent (207/696) of patients in the final cohort were Hispanic, 24% (165/696) non-Hispanic black, and 46% (324/696) non-Hispanic white. Hispanics were more likely to be female, older, and have a lower mean height standard deviation score (SDS). There were no significant differences among ethnic/racial groups regarding clearance parameters. More Hispanics had a mean hemoglobin ≥ 11 g/dl compared with non-Hispanic blacks and non-Hispanic whites (77% vs. 55% and 70%, P < 0.0001). More Hispanics compared with non-Hispanic blacks and non-Hispanic whites had a mean serum albumin ≥ 4.0/3.7 g/dl [bromcresol green/bromcresol purple laboratory method (BCG/BCP)] (50% vs. 24% and 27%, respectively, P < 0.0001). In multivariate analyses, Hispanics remained significantly more likely to achieve a mean serum albumin ≥ 4.0/3.7 g/dl (BCG/BCP) compared with non-Hispanic whites (referent) and were as likely to achieve clearance and hemoglobin targets. Pediatric Hispanic peritoneal dialysis patients experience equivalent or better intermediate outcomes of dialytic care compared with non-Hispanics. Further study is needed to understand associations of Hispanic ethnicity with outcomes such as hospitalization, transplantation, and mortality.
