Prognostic Impact of the Preservation of Activities of Daily Living on Post-Discharge Outcomes in Patients With Acute Heart Failure

Abstract

BACKGROUND: Hospitalization for heart failure (HF) carries a risk of impairment in physical activity. We assessed the association between changes in Barthel index (BI) during hospitalization and prognosis in patients with acute HF. METHODS AND RESULTS: We evaluated the BI in 256 patients with acute HF at the time of hospital admission (pre-BI) and at discharge (post-BI). All patients were followed for 1 year after discharge. BI significantly decreased during hospitalization in enrolled patients. Patients with a post-BI <60 had longer hospital stays and higher rates of non-home discharge, and had a lower 1-year survival rate than those with a post-BI ≥60. Multivariate Cox regression analysis revealed that post-BI, not pre-BI or changes in BI, significantly correlated with all-cause death and the composite of all-cause death or rehospitalization for HF for 1 year after discharge. Patients with decreasing BI during hospitalization had significantly lower all-cause death- or HF readmission-free survival following acute HF than those having a pre-BI ≥60 and changes in BI ≥0. CONCLUSIONS: Results demonstrate that low BI at discharge and decreased BI during hospitalization predicted poor outcomes in Japanese patients with acute HF. A comprehensive approach, beginning in the acute phase, aiming to maintain patients' ability to perform activities of daily living could provide better management of HF.
