Facility-Level Interpatient Hemoglobin Variability in Hemodialysis Centers Participating in the Dialysis Outcomes and Practice Patterns Study (DOPPS): Associations With Mortality, Patient Characteristics, and Facility Practices

Facility-level hemoglobin SD was associated strongly and positively with patient mortality, not tightly linked to numerous patient characteristics, but related strongly to facility anemia management practices. Facility-level hemoglobin variability may be modifiable and its optimization may improve hemodialysis patient survival.
