Health Services Research

Research in our group focuses on the systematic and long-term evaluation of the quality and outcomes of health care of people with rheumatic and musculoskeletal diseases in Germany. Using large primary and secondary data bases, developments and deficits in specialized as well as non-specialized health care are investigated. Findings are fed back to the treating physicians and inform clinical and political decision making.

An important instrument of research is the National Database of the German Collaborative Arthritis Centres. Since 1993 it has enabled our group to monitor trends in treatments and outcomes of inflammatory rheumatic diseases in more than 15,000 patients per year. Over the years, these data have substantiated how new therapeutic options and earlier access to rheumatologic care are reflected in continuously improving clinical outcomes of patients. The ability to work has increased significantly, the disease activity and the burden of illness due to pain or functional limitations have decreased.

Our group has been involved in two national research networks funded by the Federal Ministry of Education and Research (BMBF). Taking advantage of routine data from BARMER health insurance, claims data were analysed in the PROCLAIR project in combination with patient-reported outcomes from questionnaire surveys including a total of 20,000 of BARMER health insurance members. Diverging treatment concepts between rheumatologists and non-specialised physicians, as well as regional differences in health care, were detected. In addition, there were substantial differences in the provision of care depending on age and social status. Depression turned out to be an important predictor of poor clinical and socioeconomic outcomes. A collaborative work from the PROCLAIR and METARTHROS projects revealed a high burden of diabetes and other chronic comorbidities in patients with rheumatoid arthritis as well as deficits in specialized care.

All treatment guidelines in RA include recommendations for therapeutic strategies in case of unfavourable prognostic factors. Data from the early arthritis cohort CAPEA showed that autoantibodies and early erosions did not predict achievement of low disease activity or remission whereas baseline disease activity, functional limitation and obesity were predictive.
