An intervention study among elderly people. Methodological and practical experiences.

Based on a three years controlled intervention study among elderly subjects, aged 75 years or more and living in their own homes, the methodological and practical experiences achieved through interdisciplinary cooperation is described. The combination of social, medical and psychological interventions within the framework of a clinical controlled trial has documented remarkably favourable consequences for the intervention group. The planning, intervention, work up and publication periods of the study are described in the wish that future necessary intervention studies may be guided to an easier procedure.
