BACKGROUND
In a study of Italian heart failure patient-caregiver dyads, greater caregiver strain significantly predicted lower patient clinical event risk.
OBJECTIVE
The purpose of this secondary analysis was to examine this relationship in a sample from the United States.
METHODS
Data came from 92 dyads who participated in a self-care intervention. Logistic regression was used to test the relationship between baseline strain (Bakas Caregiving Outcomes Scale, divided into tertiles) and patient likelihood of events (heart failure hospitalization/emergency visit or all-cause mortality) over 8 months.
RESULTS
Nearly half of patients (n = 40, 43.5%) had an event. High (vs low) caregiver strain was associated with a 92.7% event-risk reduction, but with substantial variability around the effect (odds ratio, 0.07; 95% confidence interval, 0.01-0.63; P = .02).
CONCLUSIONS
Although findings were similar to the Italian study, the high degree of variability and contrasting findings to other studies signal a level of complexity that warrants further investigation.
背景
在一项意大利心力衰竭患者-照护者对子的研究中，照护者的压力越大，患者的临床事件风险越低。
目的
本二次分析的目的是在美国的样本中检验这种关系。
方法
数据来自 92 对参加自我护理干预的对子。逻辑回归用于检验基线压力（Bakas 照护结果量表，分为三分位数）与 8 个月内患者发生事件（心力衰竭住院/急诊就诊或全因死亡率）的可能性之间的关系。
结果
近一半的患者（n = 40，43.5%）发生了事件。高（与低）照护者压力与 92.7%的事件风险降低相关，但效应存在很大的变异性（比值比，0.07；95%置信区间，0.01-0.63；P =.02）。
结论
尽管研究结果与意大利的研究相似，但变异性程度高和与其他研究的结果对比表明存在一定的复杂性，需要进一步研究。
