Red Cell Distribution Width and Mortality in Hemodialysis Patients.

ABSTRACT:

Background

Red cell distribution width (RDW) is an index of red blood cell volume variability that has historically been used as a marker of iron deficiency anemia. More recently, studies have shown that elevated RDW is associated with higher mortality risk in the general population. However, there is lack of data demonstrating the association between RDW and mortality risk in hemodialysis (HD) patients. We hypothesized that higher RDW is associated with higher mortality in HD patients.

Study design

Retrospective observational study using a large HD patient cohort.

Setting & participants

109,675 adult maintenance HD patients treated in a large dialysis organization from January 1, 2007, to December 31, 2011.

Predictor

Baseline and time-varying RDW, grouped into
