Abstract
The rapid growth of the elderly population in high-income countries, particularly the United States, is reshaping healthcare systems and exacerbating the burden of age-related diseases. By 2060, the U.S. population aged 65 years and older is projected to nearly double, with the oldest cohort (85+) tripling in size. This demographic shift is contributing to rising mortality rates due to chronic conditions such as Alzheimer's disease, cardiovascular diseases, frailty, and multi-morbidity. Utilizing data from the National Inpatient Sample (NIS) from 2010 to 2024, this review examines key trends in mortality, hospital utilization, and the healthcare system's capacity to manage these shifts. We identify the leading causes of death, hospital admission patterns, and the increasing demand for long-term care. The paper further explores the policy implications of these trends, highlighting the need for integrated care models, geriatric specialization, and preventive healthcare strategies to address the growing demands of an aging population. By providing a comprehensive analysis of these issues, this article aims to inform healthcare policy, improve care delivery for the elderly, and promote further research in geriatric healthcare.
