Veterans Health Administration Models of Community-Based Long-Term Care: State of the Science.

The complex care needs of older adults arising at the intersection of age-related illnesses, military service, and social barriers have presented challenges to the US Department of Veterans Affairs (VA) for decades. In response, the VA has invested in centers that integrate research, education, and clinical innovation, using approaches aligned with a learning health care system, to create, evaluate, and implement new care models. This article presents an integrative review of 6 community care models developed within the VA to manage multimorbidity, complex social needs, and avoid institutional care, examining how these models address complex care needs among older adults. The models reviewed include Home Based Primary Care, Medical Foster Home, the VA Caregiver Support Program, the Resources Enhancing Alzheimer's Caregiver Health (REACH)-VA program, the Caregivers of Older Adults Cared for at Home (COACH) program, and Veteran Directed Care. Core components and evaluation outcomes for each model are summarized, along with implications for more widespread implementation and research. Each model promotes coordinated care, integrates behavioral health, and leverages interprofessional expertise. All models are cost-neutral or incur only modest cost increases to improve outcomes. Broader implementation will require interprofessional workforce development, payment model realignment, and infrastructure to evaluate outcomes in new settings. The VA provides a blueprint for infrastructure that could be adapted to other domestic and international settings. Care models successfully implemented within the VA's single-payer system hold promise to address persistent dilemmas in long-term care, such as management of multimorbidity and social drivers of health, integration and support of family caregivers, and mental health integration. These models also demonstrate the value of incorporating care approaches that have been developed or tested outside the United States and argue for greater cross-fertilization of ideas from different health systems.
