The Comprehensive Assessment and Referral Evaluation (CARE) is a new assessment technique which is intended to reliably elicit, record, grade and classify information on the health and social problems of the older person. The CARE is basically a semi-structured interview guide and an inventory of defined ratings. It is designated comprehensive because it covers psychiatric, medical, nutritional, economic and social problems rather than the interests of only one professional discipline. The style, scope and scoring of the CARE makes it suitable for use with both patients and non-patients, and a potentially useful aid in determining whether an elderly person should be referred, and to whom, for a health or social service. The CARE can also be employed in evaluating the effectiveness of that service if given.
