Research fields include economic evaluation of health care as well as health services research, with a focus on care for the mentally ill and the elderly. Currently, methods are developed and tested to measure preference-based valuations of health-related quality of life and costs in different diagnosis groups. In addition, cost-of-illness studies are carried out and disease models are developed as a basis for decision-analytic evaluation studies. Furthermore, cost-effectiveness analyses of new preventive, diagnostic and therapeutic health technologies for patients from different disease groups are conducted and new forms of funding for mental health care are evaluated.
