Contact persons: Dr. Judith Fuchs, Dr. Markus Busch, Dr. Beate Gärtner, Dr. Hildtraud Knopf, Dr. Martin Holzhausen (guest scientist), Dr. Christa Scheidt-Nave (Div. 22)

The OMAHA I study developed a conceptual framework and standardised tools for multi-dimensional measurement of multimorbidity, autonomy and quality of life in the population aged 65 and older.

In addition, the effectiveness of different methods for obtaining a random sample that is representative of the population was tested. Longitudinal follow-up studies allow the estimation of health-related changes in this group of people over a period of 36 months.

The project therefore provides methodical conditions for monitoring multimorbidity and the associated specific health and social care requirements of older people at the population level.
