Because of their longstanding relationships with patients, family physicians often are in the best position to identify signs of serious illness progression, provide support and guidance to patients and caregivers, and tailor care plans to individual needs and preferences at the end of life. Significant signs of illness progression include worsening of one or more conditions, decline in function, and increase in the number of emergency department visits or hospitalizations. Prognostication refers to estimation of the remaining life expectancy. Several tools are available to inform such estimates. Prognostication should include discussion of the expected illness progression to help patients and family members prepare, plan, and cope. Advance care planning, ideally started before or early in the course of illness, should include identification of patient surrogate decision-makers as well as a discussion of patient values, priorities, and care preferences. Planning should continue and evolve to inform care plans that match patient and family member priorities at each stage of illness. Family physicians should be familiar with resources available in their communities to support care plans, including palliative care subspecialists, home- and facility-based palliative care teams, and hospice physicians.
