PURPOSE
Clinically validate (using Fehring's model) characteristics of the nursing diagnosis (ND) of decreased cardiac output (DCO) in 29 patients with decompensated heart failure.
METHODS
Cross-sectional study conducted in a Brazilian university hospital.
FINDINGS
According to the reliability rate (R) between the experts, the major characteristics (R ≥ 0.80) were fatigue, dyspnea, edema, orthopnea, paroxysmal nocturnal dyspnea, and elevated central venous pressure, and the secondary characteristics were weight gain, hepatomegaly, jugular vein distension, palpitations, crackles, oliguria, coughing, clammy skin, and skin color changes.
CONCLUSION
Characteristics with R > 0.50 and ≤1 were valid in the ND of DCO. IMPLICATIONS FOR THE NURSING PRACTICE: Clinical validation studies are necessary to determine the adequacy of this diagnosis and its determining characteristics with Taxonomy II.
目的
运用费林模型对29例失代偿性心力衰竭患者心输出量降低（DCO）的护理诊断（ND）特征进行临床验证。
方法
在巴西一家大学医院开展横断面研究。
结果
根据专家之间的信度率（R），主要特征（R≥0.80）为疲劳、呼吸困难、水肿、端坐呼吸、阵发性夜间呼吸困难及中心静脉压升高，次要特征为体重增加、肝肿大、颈静脉怒张、心悸、啰音、少尿、咳嗽、皮肤湿冷及皮肤颜色改变。
结论
R>0.50且≤1的特征在DCO的ND中有效。对护理实践的启示：临床验证研究对于确定该诊断及其在护理诊断分类法II中的决定特征是否恰当很有必要。
