Key result
High caregiver strain is linked to ~93% fewer HF events or deaths versus low strain.
Why the study?
The relationship between caregiver strain and heart failure patient clinical event risk observed in an Italian study needed examination in a US sample.
Does high caregiver strain reduce the likelihood of clinical events in heart failure patients?
Cohort (n=92)
Does high caregiver strain reduce the likelihood of clinical events in heart failure patients?
Odds Ratio: 0.07 (95% CI 0.01–0.63)
p-value: p=.02
High caregiver strain is paradoxically associated with a significantly lower risk of clinical events in heart failure patients, though with substantial variability.
Should not alter HF care; hypothesis-generating association needing prospective confirmation.
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.

Bidwell et al. (2020) conducted a cohort in heart failure (n=92). High caregiver strain vs. Low caregiver strain was evaluated on heart failure hospitalization/emergency visit or all-cause mortality (OR 0.07, 95% CI 0.01-0.63, p=.02). High caregiver strain was associated with a 92.7% reduction in heart failure events or mortality compared to low strain (OR 0.07; 95% CI 0.01-0.63; P=.02).
