Hemoglobin variability: impact on anemia management practices.
Data indicate that a wide range of factors can contribute to inter- and intrapatient variability in hemoglobin (Hb) levels in dialysis patients. Some of these factors are controllable and can be minimized by implementing nursing practices that encourage consistent and accurate Hb assessments and management. However, many of these factors are difficult or impossible to modify, and natural intrapatient variations are therefore expected and unavoidable. When natural variability leads to Hb levels that temporarily exceed 12 g/dL, appropriate protocol-guided nursing responses should include long-term, patient-specific laboratory trend analyses, data-driven adjustments in the anemia management prescription, and accurate nursing documentation of assessments, interventions, and outcomes.
