PURPOSE Identify the prevalence of the nursing diagnosis (ND) Fatigue in patients with heart failure (HF) and to analyze the accuracy of its defining characteristics (DCs). METHODS 50 patients were assessed for Fatigue through a distance ambulated <300m during the Six‐Minute Walking Test (6MWT) and the report of insufficient energy. Sensitivity, specificity, positive and negative predictive values were calculated for the DCs associated with Fatigue. FINDINGS The prevalence of Fatigue was 48%. No DCs were sensitive and specific for determining Fatigue. CONCLUSIONS There were no DCs accurate enough to infer Fatigue. IMPLICATIONS FOR PRACTICE A distance ambulated <300m during the 6MWT should be included as a DC of Fatigue.
