Informal caregivers--primarily family members--are the foundation of rehabilitation, chronic care, and long-term support for older persons. The growing population of older persons and the changing health care delivery system (for example, shortened hospital stays) demand more of family caregivers and increase the toll on their health. To help them cope with these demands, nurses and social workers, who treat diverse older populations, must have cultural competence to enable them to practice effectively with caregivers. Along with increasing the emphasis on evidence-based practice, health care education is moving to a competence-based approach with clearly measured outcomes. In this article, literature from the past decade, especially systematic reviews of evidence-based-practice dissemination and training, is used to inform nurse and social worker competence in supporting family caregivers. The reviews were from the medical education literature as well as from nursing and social work education, and some studies involved students and residents, not only postgraduate practitioners.
