Factors Associated With Mortality and Hospice Use Among Medicare Beneficiaries With Heart Failure Who Received Home Health Services.

Background: Although many Medicare beneficiaries with heart failure (HF) are discharged with home health services, little is known about mortality rates and hospice use in this group.

Objectives: To identify risk factors for 6-month mortality and hospice use among patients hospitalized due to HF who receive home health care, which could inform efforts to improve palliative and hospice use for these patients.

Methods: A retrospective cohort analysis was conducted in a 100% national sample of Medicare fee-for-service beneficiaries with HF who were discharged to home health care between 2017 and 2018. Multivariable Cox regression models examined factors associated with 6-month mortality, and multivariable logistic regression models examined factors associated with hospice use at the time of death.

Results: A total of 285,359 Medicare beneficiaries were hospitalized with HF and discharged with home health care; 15.5% (44,174) died within 6 months. Variables most strongly associated with mortality included: age > 85 years (hazard ratio [HR] 1.66, 95% CI 1.61-1.71), urgent/emergency hospital admission (HR 1.68, 1.61-1.76), and "serious" condition compared to "stable" condition (HR 1.64, CI 1.52-1.78). Among 44,174 decedents, 48.2% (21,284) received hospice care at the time of death. Those with lower odds of hospice use at death included patients who were: < 65 years (odds ratio [OR] 0.65, CI 0.59-0.72); of Black (OR 0.64, CI 0.59-0.68) or Hispanic race/ethnicity (OR 0.79, CI 0.72-0.88); and Medicaid-eligible (OR 0.80, CI 0.76-0.85).

Conclusions: Although many patients hospitalized for HF are at risk of 6-month mortality and may benefit from palliative and/or hospice services, our findings indicate under-use of hospice care and important disparities in hospice use by race/ethnicity and socioeconomic status.
