Randomized Controlled TrialRevisiting survival differences by race and ethnicity among hemodialysis patients: the Dialysis Outcomes and Practice Patterns Study.
Hemodialysis (HD) patients who are identified as belonging to racial or ethnic minority groups have longer survival than non-Hispanic white HD patients. This study sought to determine to what extent this survival difference is explained by comprehensive adjustment for measurable case-mix and treatment characteristics. A cohort analysis was conducted among 6677 patients between 1996 and 2001 in the American arm of the first phase of the Dialysis Outcomes and Practice Patterns Study, a prospective observational study. ⋯ The associations of race/ethnicity with survival varied little by duration of ESRD and were not influenced substantially by different rates of kidney transplantation among patients who were on HD. The survival advantages for racial and ethnic minority groups on HD are explained largely by measurable case-mix and treatment characteristics. Individual racial minority group or Hispanic patients should not be expected to survive longer on HD than non-Hispanic white patients with similar clinical attributes.

Association of mortality and hospitalization with achievement of adult hemoglobin targets in adolescents maintained on hemodialysis.
With the use of data from the Centers for Medicare & Medicaid Services' ESRD Clinical Performance Measures Project (October through December 1999 and 2000) linked with US Renal Data System hospitalization and mortality records, whether achieving adult target hemoglobin (Hb) levels in adolescents who are on hemodialysis (HD) was associated with decreased risk for death or hospitalization was assessed. Of 677 adolescents, 238 were hospitalized and 54 died. In bivariate analysis, 11.7% with Hb <11 g/dl at study entry died versus 5% of those with initial Hb > or =11 g/dl (P = 0.001); 40.3% with baseline Hb <11 g/dl were hospitalized versus 31.1% with initial Hb > or =11 g/dl (P = 0.013). ⋯ For hospitalization, no statistically significant difference in risk between Hb categories was found. This observational study of adolescents who are on HD is consistent with adult literature showing decreased mortality in patients who have ESRD and meet adult Hb targets. Further studies in the form of randomized, clinical trials are needed to assess optimal Hb levels for adolescents who are on HD.
