EXECUTIVE SUMMARY: Home hospital care (HHC) is a new and exciting concept that holds the promise of achieving all three components of the Triple Aim and reducing health disparities. As an innovative care delivery model, HHC substitutes traditional inpatient hospital care with hospital care at home for older patients with certain conditions. Studies have shown evidence of reduced cost of care, improved patient satisfaction, and enhanced quality and safety of care for patients treated through this model. The steady growth in Medicare Advantage enrollment and the expansion in 2020 of the Centers for Medicare & Medicaid Services (CMS) Hospitals Without Walls program to include acute hospital care at home creates an opportunity for hospitals to implement such programs and be financially rewarded for reducing costs. Capacity constraints exacerbated by the COVID-19 pandemic suggest that now is the ideal time for healthcare leaders to test and advance the concept of HHC in their communities.
