Multiple sclerosis in Germany: data analysis of administrative prevalence and healthcare delivery in the statutory health system

Abstract

BACKGROUND: Healthcare-utilization data for multiple sclerosis (MS) are scarce in Germany. The Purpose of the study was to analyse administrative prevalence of MS, medication use and type of specialists involved in MS treatment in the outpatient setting in Bavaria. METHODS: Pseudonymized claims data from Bavarian Statutory Health Insurance (SHI)-accredited physicians were used. Administrative prevalence of MS was defined as having ≥1 MS diagnosis (International Classification of Diseases, 10th edition, code G35) documented by a neurologist or psychiatrist, or ≥1 prescription for disease-modifying drugs (DMDs)). The administrative prevalence calculated for Bavaria was projected to Germany. DMD prescription and involvement of different specialities in health care service for MS patients was analysed. RESULTS: Administrative prevalence of MS in Bavaria increased from 0.123% to 0.175% of insured persons between 2005 and 2009; when projected, this yielded ~102,000-143,000 patients with MS in the German population. The percentage of patients receiving ≥1 DMD prescription increased from 45.5% to 50.5%. Patients with MS were mainly treated by neurologists in the ambulatory care setting. CONCLUSIONS: These results provide important information on the administrative prevalence of MS in Bavaria and on healthcare provision for patients, which is relevant for resource planning in the healthcare sector.
