Most elderly patients hospitalized for heart failure lack the abilities needed to perform the tasks required for self-care: impact on outcomes

Abstract

Aim: To evaluate the abilities to perform essential tasks for heart failure (HF) self-management in elderly patients, and its influence on post-discharge prognosis.

Methods and results: Overall, 415 patients ≥70 years old hospitalized for HF were included and followed during 1 year. The ability to perform six specific tasks (use of a scale, weight registration, diuretic identification, knowledge of salted foods, oedema identification, and treatment adjustment) was tested and distributed on terciles (T) of performance. Correlation with the self-administered questionnaire European HF Self-care Behaviour Scale (EHFScBS) was evaluated. The independent influence of self-care on 1-year mortality and readmission risks was calculated by Cox proportional hazards regression analysis. Mean age was 80.1 years. On average, patients could perform 2.9 ± 1.6 of self-care tasks, and only 5.3% could perform the six tasks correctly. Patients with previous HF self-care education had slight better performance (3.2 ± 1.6 vs 2.8 ± 1.6, P < 0.02). A weak correlation was found between EHFScBS and number of tasks correctly performed (r = -0.135; P = 0.006). One-year mortality in T1, T2, and T3 patients was 33.0%, 20.7%, and 14.1%, respectively (P = 0.002). Multivariable analysis showed T2 and T3 groups having a lower adjusted mortality risk compared with T1 [hazard ratio (HR) 0.58; 95% confidence interval (CI) 0.32-1.03; and HR 0.40; 95% CI 0.21-0.77, respectively], without differences in readmissions.

Conclusion: Most elderly patients admitted for HF are unable to perform several essential tasks needed for HF self-care. Self-perception of care was poorly correlated with real ability, and poor self-care ability was associated with higher 1-year mortality risk.
