Home-Time, Mortality, and Readmissions among Patients Hospitalized with Heart Failure: A Baseline Prior to IMPLEMENT-HF

BACKGROUND: Home-time is an emerging, patient-centered outcome that represents the amount of time a patient spends alive and outside of health care facility settings, comprising of hospitals, skilled nursing facilities, and acute rehabilitation centers. Studies evaluating home-time in the context of heart failure are limited, and the impact of quality improvement interventions on home-time has not been studied. METHODS: Medicare beneficiaries aged 65 years or older who were hospitalized for heart failure in the Get With the Guidelines-Heart Failure registry between 2019 and 2021 were included. Postdischarge home-time, mortality, and readmission rates at 30 days and 1 year were calculated with the goal of establishing baseline metrics before the initiation of IMPLEMENT-HF, a multicenter quality improvement program aimed at improving heart failure management. RESULTS: Overall, 66 019 patients were included across 437 sites. Median 30-day and 1-year home-time were 30 (18-30) and 333 (139-362) days, respectively. Only 22.1% of patients experienced 100% home-time in the year after discharge. Older patients spent significantly less time at home, with a median 1-year home-time of 302 (86-359) compared with 345 (211-365) days in patients over 85 and those between 65 and 74 years old, respectively (P<0.001). Black patients also experienced the least amount of home-time with only 328 (151-360) days at 1-year follow-up. Rates of heart failure readmission and all-cause mortality 1-year post-discharge were high at 29.8% and 37.0%, respectively. CONCLUSIONS: In this contemporary multicenter cohort, patients hospitalized with heart failure spent a median of 91.2% of their time in the year after discharge alive and at home, largely driven by high mortality rates. These findings serve as a preimplementation baseline for IMPLEMENT-HF, which will evaluate the impact of targeted heart failure initiatives on home-time and other clinical outcomes.
