Incidence of Hospitalization-Associated Disability in Older Patients With Heart Failure

Background: This study determined the incidence of hospitalization-associated disability (HAD) and its characteristics in older patients with heart failure in Japan.Methods and Results: Ninety-six institutions participated in this nationwide multicenter registry study (J-Proof HF). From December 2020 to March 2022, consecutive heart failure patients aged ≥65 years who were prescribed physical rehabilitation during hospitalization were enrolled. Of the 9,403 patients enrolled (median age 83.0 years, 50.9% male), 3,488 (37.1%) had HAD. Compared with the non-HAD group, the HAD group was older and had higher rates of hypertension, chronic kidney disease, and cerebrovascular disease comorbidity.
