Healthcare System Sustainability for an Aging Population in the United States: Economic Challenges and Policy Pathways

Population aging is one of the major long-term economic challenges facing the U.S. healthcare system. As life expectancy increases and the older-adult population expands, demand is rising for chronic disease management, hospital care, prescription medication, rehabilitation, home care, long-term services and supports, and caregiver assistance. Existing studies have examined aging-related healthcare costs, long-term care financing, medical expenditure burden, workforce shortages, and family caregiving, but these issues are often analyzed separately rather than as one integrated economic sustainability problem. This paper examines the economic sustainability of U.S. healthcare systems serving an aging population by focusing on three major pressures: increasing healthcare demand, long-term care financing strain, and healthcare delivery-capacity constraints. Drawing on peer-reviewed studies, government reports, and policy analyses published before 2025, the paper identifies a gap in the literature: limited integration of Medicare and Medicaid financing, workforce capacity, chronic disease burden, care fragmentation, unpaid caregiving, preventive care, and home- and community-based services into a single sustainability framework. The paper proposes a conceptual framework that links cost control, access, workforce development, technology-enabled care coordination, long-term care reform and caregiver support. The findings suggest that economic sustainability cannot be achieved through increased healthcare spending alone. Instead, the U.S. healthcare system must shift from a reactive, hospital-centered model toward a preventive, coordinated, technology-supported, home and community-based model that improves affordability, access, quality, and aging-care outcomes.
