title: Usefulness of the Diagnosis "Decreased Cardiac Output (00029)" in Patients With Chronic Heart Failure.
abstract: OBJECTIVE
  To determine the clinical and construct validity of the nursing diagnosis "decreased cardiac output" (DCO) in patients with chronic heart failure.
  
  
  METHODS
  Cross-sectional study.
  
  
  RESULTS
  A total of 200 people were studied. The defining characteristics with the highest prevalence were as follows: arrhythmia (62.5%) and fatigue (61.5%). Adjustment measures such as infit and outfit were maintained between 0.50 and 1.56 and the total variance explained by the measures was 29.3%.
  
  
  CONCLUSIONS
  This study determined the clinical validity of the nursing diagnosis DCO. Regarding construct validity, adjustment of the defining characteristics to the Rasch model was observed.
  
  
  CONCLUSIONS
  This study improves the evidence-based practice of nursing and strengthened the role of the nurse who leads care to this population.
