[Health care needs, brain functional ability, social behavior and social attendant circumstances of elderly patients in community and institutionalized geriatric care in the city of Zurich].

All aged persons being helped by community nursing-services, the house-helper service, the housekeeper service, or living in a home for the aged or in an apartment for seniors in a representative area of the city of Zurich are compared to all patients in nursing-homes of the city. This study included the size of social network measured by the number of different regular visitors, the number of different medications taken daily, the cognitive abilities measured by the Mini Mental Status, the activities of daily living and the social skills rated by the care-givers as well as the intensity of the care given. The groups were similar in age and sex-distribution but the nursing-home patients differed significantly in all other parameters from the others. In contrast, no significant differences could be found between persons receiving care in their homes and those in institutions for the aged.
