This article describes the Lee Geropalliative Caring Model (GCM), a situation-specific theory that guides geropalliative care, defined as the care of older adults in the last 2 years of life. Underpinned by the theory of human caring, the GCM offers a framework for achieving the person/family outcome of well-being by suggesting caring interventions within 4 priority domains: aligning care, keeping safe, comforting body/mind/spirit, and facilitating transitions to persons with late-stage illness, including frailty and dementia. The GCM can be used to inform practice, policy, education, and research.
