Functional ability of patients on dialysis: the critical role of anemia.

Maintining hemoglobin (Hb) levels in the range (11 to 12 g/dL) recommended by the National Kidney Foundation's Kidney Disease Quality Initiative (NKF/KDOQI) has been shown to significantly improve functional ability in patients on dialysis. The combination of partial anemia correction and an individualized exercise program yields additional incremental benefits. Nurses fulfill a crucial role in ensuring that appropriate Hb levels are maintained while at the same time encouraging patients to improve their physical conditioning and functional status.
