Leveraging Health Services Research to Address Aging Health Equity.

To achieve optimal, equitable health outcomes for all older adults, the United States desperately needs equity in access to, quality of, and cost of aging care. To illustrate these needs, we discuss the current inequitable state of frailty care. Frailty disproportionately affects marginalized populations, yet these populations struggle to access high-quality geriatrics care and long-term care services and supports (LTSS) that mitigate frailty, leading to accelerated frailty trajectories. Health services research can provide the data needed to document, elucidate, and address health inequities in frailty care, including early identification and referral of frail adults to specialized care and financing LTSS.
