This study aimed to investigate whether hospitalization in older patients with heart failure (HF) leads to a worsening of independence in activities of daily living (ADL) and difficulties in ADL, and whether these difficulties can predict readmission for HF. The results showed that hospitalization triggered a decline in independence and an increase in difficulties in ADL in older HF patients, and these difficulties were relevant factors for the risk of readmission.
Aims The aim of this study was to clarify whether worsening of independence in activities of daily living (ADL) and also difficulties in ADL are triggered by hospitalization in older patients with heart failure (HF) and whether difficulties in ADL can predict readmission for HF regardless of independence in ADL in these patients. Methods and results We enrolled 241 HF patients in the present multi-institutional, prospective, observational study. The patients were divided according to age into the non-older patient group (<75 years, n = 137) and the older patient group (>= 75 years, n = 104). The Katz index and the Performance Measure for Activities of Daily Living-8 (PMADL-8) were used to evaluate independence and difficulties in ADL, respectively. The endpoint of this study was rehospitalization for HF. Independence as indicated by the Katz index at discharge was significantly lower than that before admission only in the older patient group, and the value of the PMADL-8 at discharge was significantly higher than that before admission (P < 0.001). In all patients, after adjusting for the Katz index and other variables, PMADL-8 score was a significant predictor of rehospitalization for HF (hazard ratio 1.50; 95% confidence interval 1.07-2.13; P = 0.021). Conclusions Worsening of both independence and difficulties in ADL was triggered by hospitalization in older HF patients, and difficulties in ADL were relevant factors for risk of rehospitalization regardless of independence in ADL. These findings indicate the importance of preventing not only decreased independence but also increased difficulties in ADL during and after hospitalization.
