Impact of in-hospital cardiac rehabilitation on hospital-associated disability after transcatheter aortic valve implantation

Hospital-associated disability (HAD), a decline in the ability to perform activities of daily living (ADL) during hospitalization, is a modifiable target in integrated care for older adults. The aim of this study was to determine the impact of inpatient cardiac rehabilitation (CR) on the development of HAD in older patients with aortic stenosis undergoing transcatheter aortic valve implantation (TAVI). Older patients undergoing TAVI were extracted from the Japanese nationwide database (JROAD-DPC) from April 2014 to March 2021 and were divided into patients receiving inpatient CR (CR group) and a non-CR group. HAD was defined as a decrease in the Barthel Index (BI) score ≥5 points at discharge compared with the score at admission. Of 19,789 eligible patients, 17,066 (86%) underwent inpatient CR. The overall prevalence of HAD was 9.6%, with a lower incidence in the CR group than in the non-CR group (8.8% vs. 14.2%, p
