The modified prediction method, obtained after calibration of the original model, performs well in an independent patient sample and gives more accurate predictions than the original model.

Background: Heart failure (HF) requires a comprehensive nutrition assessment. Biochemical markers, including serum albumin, are particularly inadequate in this population due to confounding by fluid status and other factors. We assessed whether there is congruence between serum albumin levels and malnutrition assessed using the six indicators of malnutrition, in adult patients with end-stage HF who were hospitalized in the HF unit at University Hospitals Cleveland Medical Center.
