Abstract

Highlights: Patients with early rehospitalization had a higher risk for all-cause deaths. Poor compliance with fluid restriction was major factor of early rehospitalization. Poor compliance with activity restriction was major factor of early rehospitalization. Univariate analysis revealed physical frailty as an important risk factor for death from all causes. Abstract: Background: Recent reports have revealed that patients who experienced early rehospitalization for heart failure (HF) had worse prognoses in terms of all-cause and cardiovascular deaths as compared to those who did not. However, precipitating factors for early rehospitalization for HF remain unknown. In this study, we assessed the precipitating factors for early rehospitalization and their impact in patients with HF. Methods and results: We consecutively included 242 patients (mean age: 80.4 years, females: 46.3%) with a history of rehospitalization for HF. They were divided into 2 groups: the early rehospitalization group (71 patients who were readmitted within 3 months of discharge) and the late rehospitalization group (171 patients who were readmitted after more than 3 months following discharge). During the mean follow-up period of 1, 144 days (range: 857–1, 417 days), 121 patients (50.0%) died. Kaplan–Meier analysis revealed that patients in the early rehospitalization group had worse prognosis (all-cause death and cardiovascular death) than those in the late rehospitalization group (log-rank p <0.001). As the major precipitating factor for rehospitalization, poor compliance with the doctor's instructions on fluid and physical activity restrictions (determined by the patients or their families admittance of non-compliance with the instructions given at the time of discharge) was higher in the early rehospitalization group than in the late rehospitalization group [poor compliance with fluid restriction: 19.7% vs. 7.6% ( p = 0.006), poor compliance with physical activity restriction: 21.1% vs. 9.4% ( p = 0.013)]. Conclusions: We concluded that early hospital readmission in patients with HF was associated with higher mortality rates. Compared to late rehospitalization, precipitating factors for early rehospitalization were more strongly dependent on the self-care behaviors of the patients. A more effective approach, such as multidisciplinary intervention, is essential to prevent early hospital readmission and subsequent poor prognosis.
