Abstract

Background and objectives: National Kidney Foundation Dialysis Outcomes Quality Initiative practice guidelines recommend serum albumin ≥4.0 g/ dl for adults who are on hemodialysis. There is no established pediatric target for albumin and little evidence to support use of adult guidelines. This study examined the association between albumin and risk for death and hospitalization in adolescents who are on hemodialysis. Design, setting, participants, & measurements: This retrospective cohort study linked data on patients aged 12 to 18 yr in 1999 and 2000 from the Centers for Medicare and Medicaid Services' End Stage Renal Disease Clinical Performance Measures Project with 4-yr hospitalization and mortality records in the United States Renal Data System. Albumin was categorized as <3.5/3.2, ≥3.5/3.2 and <4.0/3.7, and ≥4.0/3.7 g/dl. Results: Of 675 adolescents, 557 were hospitalized and 50 died. Albumin ·4.0/3.7 g/dl was associated with male gender, Hispanic ethnicity, and higher hemoglobin level. Those with albumin ≥4.0/3.7 g /dl had fewer deaths per 100 patient-years and fewer hospitalizations per time at risk. In multivariate analysis, patients with albumin ≥4.0 /3.7 g/dl had 57% decreased risk for death. Poisson regression showed progressive decrease in hospitalization risk as albumin level increased; however, confidence intervals were similar between albumin ≥4.0/3.7 g /dl and albumin ≥3.5/3.2 and <4.0/3.7 g/dl. Conclusions: This study demonstrates decreased mortality and hospitalization risk with albumin ≥3.5/3.2 g/dl and suggests that adolescent hemodialysis patients who are able to achieve serum albumin ≥4.0/3.7 g/dl may have the lowest mortality risk.
