基于慢性疾病轨迹模式的护理干预对心力衰竭患者心功能、运动能力、心理状态及生活质量的影响

Effect of nursing intervention based on chronic disease trajectory model on heart function,exercise capacity,mental state and quality of life in patients with heart failure

目的:探讨基于慢性疾病轨迹模式的护理干预对心力衰竭患者心功能、运动能力、心理状态及生活质量的影响。方法:采用随机数表法将140例心力衰竭患者分为观察组(n=70)和对照组(n=70),对照组采用常规护理干预,观察组采用基于慢性疾病轨迹模式的护理干预,干预周期3个月,比较两组患者干预前后左心室射血分数(LVEF)、N末端B型利钠肽原(BNP)、6 min步行距离、握力、焦虑、抑郁、希望水平、生活质量评分的差异。结果:干预后,观察组患者LVEF、6 min步行距离、握力、希望水平总分及各维度评分均高于对照组(P<0.05),观察组患者BNP、焦虑评分、抑郁评分、焦虑发生率、生活质量总分及各维度评分均低于对照组(P<0.05)。结论:基于慢性疾病轨迹模式的护理干预能改善患者心功能、提高患者运动能力,减少焦虑抑郁,提高希望水平,改善生活质量。

Objective:To premilinarily explore the effect of nursing intervention based on chronic disease trajectory model on the heart function,exercise capacity,mental status and quality of life in patients with heart failure.Methods:One hundred and forty patients with heart failure were randomized into observational group(n=70)and control group(n=70)using random digital table.Patients in the control group received simple conventional interventions,and those in the observational group were given additional intervention based on chronic disease trajectory model besides routine care for three consecutive months.Then the two groups were compared concerning the changes of Left ventricular ejection fraction(LVEF),N-terminal pro-B-type natriuretic peptide(BNP),6-min walking distance,grip strength,anxiety,depression,level of hope,and scoring on the quality of life before and after intervention.Results:After intervention,LVEF,6-min walking distance,grip strength and the level of hope were significantly higher in the observational group than in the control group(P<0.05),yet BNP,scoring on anxiety and depression,incidence of anxiety and quality of life were generally lower in the observational group than in the control group(P<0.05).Conclusion:Nursing intervention based on chronic disease trajectory model can improve patients′cardiac function and exercise ability,reduce anxiety and depression,increase the level of hope level,and improve the quality of life.
