[Long-term Trends in Rheumatology Care : Achievements and Deficits in 25 years of the German National Rheumatology Database]

Background: Since 1993, data on the care and quality of life of patients with inflammatory rheumatic diseases have been collected in the German National Database (NDB) of the regional collaborative rheumatology centers.

Objective: In this review long-term trends on treatment, disease activity and gainful employment of the most common inflammatory rheumatic diseases are presented and the most important analyses from 25 years of the NDB are summarized.

Methods: Between 15 and 17 rheumatological institutions take part in the core documentation and once a year collect data from a total of more than 10,000 patients. The rheumatologists document the disease status and care, the patients report on their state of health and the effects of the disease.

Results: The biologics era at the beginning of the twenty-first century has led to changes in the therapeutic spectrum of most inflammatory rheumatic diseases, especially in rheumatoid arthritis and ankylosing spondylitis. Some basic therapies formerly used are hardly used anymore and glucocorticoids are used less frequently. Methotrexate has remained the standard therapy for rheumatoid arthritis over the years. Nowadays, nearly 30% of patients with rheumatoid arthritis receive treatment with biologics. Disease activity, functional and social restrictions have decreased across all diseases.

Conclusion: The improved health status of many patients with rheumatic diseases confirms the high level of care provided by the rheumatism centers involved in the NDB. The increasing specification of measuring instruments and the standardization of documentation systems are major challenges that the NDB will have to face in the coming years if it is to remain in the digital age.
