[Social aspects in diagnosis and therapy of very elderly patients. Initial experiences with a newly developed questionnaire within the scope of geriatric assessment].

To evaluate social aspects of elderly patients which are important for diagnosis and therapy within geriatric assessment, a questionnaire was developed and validated. Raters showed a high degree of agreement on the scale, which contains social contacts and support, activities, economic situation, and housing conditions (0.92-0.97; p < 0.05). Compared to the interrater reliability the test-retest reliability was somewhat lower (0.75), but also significant at the 5% level. The internal consistency showed high values between 0.72-0.89. In order to evaluate the validity of the screening test the answers of the patients were compared with the assessment of the therapeutic team. The team had information from a home visit, patients spouse, relatives, neighbors, community nurses and/or general practitioners. There was a significant relationship (p < 0.01) between therapeutic assessment and the scale (r = 0.51). Sensitivity, specificity, and total efficiency also attained sufficiently high values at a cut-off of 16/17 for the complete scale (max. 25 points). The test is easily and quickly performed; its acceptance is high. Social data relevant for treatment and discharge planning can thus be obtained and patients can be identified, for whom a home visit seems to be useful.
