A Federal mandate to provide comprehensive care for the aged population in this country has stimulated program planning in gerontology by mental health professionals. Introduction of the geriatric nurse practitioner into the mental health care system is viewed as one means of attempting to increase both the availability and quality of primary mental health care in the community mental health center. This nurse functions at an "intermediate level" in relationship to traditional nursing and medical roles. Her role is to assess nursing needs of the elderly, to plan and implement care, and to evaluate the effectiveness of such care. Educational preparation for certification as a geriatric nurse is discussed. A summary of the duties of this nurse practitioner in a community health center include: (1) assess health needs of patients; (2) support/ coordinate community health care; (3) counsel and teach; (4) advocate; and(5) manage patients with chronic problems.
