Ultrafiltration Rate and Mortality in Maintenance Hemodialysis Patients.

ABSTRACT:

Background

Observational data have demonstrated an association between higher ultrafiltration rates and greater mortality among hemodialysis patients. Prior studies were small and did not consider potential differences in the association across body sizes and other related subgroups. No study has investigated ultrafiltration rates normalized to anthropometric measures beyond body weight. Also, potential methodological shortcomings in prior studies have led to questions about the veracity of the ultrafiltration rate-mortality association.

Study design

Retrospective cohort.

Setting & participants

118,394 hemodialysis patients dialyzing in a large dialysis organization, 2008 to 2012.

Predictors

Mean 30-day ultrafiltration rates were dichotomized at 13 and 10mL/h/k
