Social workers from clinical, academic, and research settings met in 2002 for a national Social Work Leadership Summit on Palliative and End-of-Life Care. Participants placed the highest priority on the development and broad dissemination of a summary document of the state-of-the-art practice of social work in palliative and end-of-life care. Nine Summit participants reviewed the literature and constructed this detailed description of the knowledge, skills, and values that are requisite for the unique, essential, and appropriate role of social work. This comprehensive statement delineates individual, family, group, team, community, and organizational interventions that extend across settings, cultures, and populations and encompasses advocacy, education, training, clinical practice, community organization, administration, supervision, policy, and research. This document is intended to guide preparation and credentialing of professional social workers, to assist interdisciplinary colleagues in their collaboration with social workers, and to provide the background for the testing of quality indicators and "best practice" social work interventions.
