Background: There is limited information regarding outcomes of dialytic care for Hispanic adolescent hemodialysis patients.
Methods: Ethnicity information was collected for all adolescent in-center hemodialysis patients for the Centers for Medicare & Medicaid Services 2000 End-Stage Renal Disease (ESRD) Clinical Performance Measures Project. Associations between intermediate outcomes and Hispanic ethnicity were determined. Associations of ethnicity and other demographic/clinical variables with hospitalization and transplantation during the 12-month follow-up period were examined.
Results: Twenty-two percent of patients were identified as Hispanic; 40%, as non-Hispanic black; and 32%, as non-Hispanic white. Hispanic patients were younger and more likely to have congenital/urological causes of ESRD. More Hispanic patients had a mean single-pool Kt/V of 1.2 or greater compared with non-Hispanic blacks and non-Hispanic whites (87% versus 73% and 79%; P = 0.036). More Hispanic patients had a mean serum albumin level of 3.5/3.2 g/dL (bromcresol green/bromcresol purple method) or greater (> or = 35/32 g/L; 91% versus 82% and 76%; P = 0.017). More Hispanic patients compared with non-Hispanic blacks and non-Hispanic whites were dialyzed with a catheter for 90 days or longer (30% versus 21% and 23%; P = 0.027). In the final multivariate Cox proportional hazard models, Hispanic patients were at a slightly decreased risk for hospitalization compared with non-Hispanics (adjusted hazard ratio [adjHR], 0.63; P = 0.031) and were as likely to undergo a first transplantation as non-Hispanic whites (adjHR, 0.56; P = 0.099).
Conclusion: Adolescent Hispanic hemodialysis patients experience equivalent or better intermediate outcomes of dialytic care than non-Hispanics. They experienced a decreased risk for subsequent hospitalization and are as likely to undergo transplantation within 12 months as non-Hispanic whites.
