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. IMPLICATIONS FOR NURSING PRACTICE: This study improves the evidence-based practice of nursing and strengthened the role of the nurse who leads care to this population. OBJETIVO: Determinar la validez clínica y de constructo del diagnóstico de enfermería “Disminución del Gasto Cardíaco” en pacientes con falla cardíaca crónica. MÉTODOS: Estudio de corte transversal. RESULTADOS: Un total de 200 pacientes fueron estudiados. Las características definitorias con las mayores prevalencias fueron: arritmia (62.5%) y fatiga (61.5%). Medidas de ajuste como el infit y outfit se mantuvieron entre 0.50 y 1.56. El total de la varianza explicada por las medidas fue de 29.3%. CONCLUSIONES: Este estudio determinó la validez clínica del diagnóstico de enfermería “Disminución del Gasto Cardíaco”. En cuanto a la validez de constructo, se observó que 19 de las 21 características definitorias se ajustaron al modelo Rasch. IMPLICACIONES PARA LA PRÁCTICA DE ENFERMERÍA: Este estudio mejora la práctica basada en la evidencia de enfermería y fortalece el rol de las enfermeras que lideran el cuidado en esta población.
