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.

照顾者劳损和心力衰竭患者临床事件风险：先前工作的延伸

背景 

在对意大利心力衰竭患者-护理人员二人组的研究中，护理人员压力越大，患者临床事件风险越低。

客观的 

本次分析的目的是在来自美国的样本中检查这种关系。

方法 

数据来自参与自我保健干预的 92 个二人组。Logistic回归用于测试基线应变（Bakas Caregiving Outcomes Scale，分为三分位数）与患者8个月内发生事件（心力衰竭 住院/急诊或全因死亡率）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）护理人员压力与 92.7% 的事件风险降低相关，但在效果方面存在很大差异（优势比，0.07；95% 置信区间，0.01–0.63；P = .02）。

结论 

尽管结果与意大利的研究相似，但与其他研究的高度可变性和对比结果表明，其复杂程度值得进一步调查。
