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

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.

A population-based study comparing biosimilar versus originator erythropoiesis-stimulating agent consumption in 6,117 patients with renal anaemia.

AIMS: There are concerns that biosimilar erythropoiesis-stimulating agents (ESAs) are less effective than the originator ESAs. The objective of our study was to investigate differences between originator and biosimilar ESA utilisation based on defined daily doses (DDD), doses upon switching, differences between short- and long-acting ESAs and prescribed daily doses (PDD) of either ESA in ambulatory patients with renal anaemia undergoing chronic maintenance haemodialysis [chronic kidney disease (CKD) stage 5]. METHODS: Patients with CKD stage 5 and specific pharmacotherapy with ESAs for at least six 3-month periods (accounting quarters) were selected from a population-based database of accounting information of Bavarian physicians and pharmacy claims data (January 2008 to December 2010). The DDD was used to determine mean ESA consumption. Descriptive statistics were used to describe the results. RESULTS: In our study, 6,177 CKD stage 5 patients received ESAs for ≥6 accounting quarters, of whom 64.4 % received originator ESAs, 21.1 % received biosimilars and 14.6 % received any sequence originator and biosimilar (total of 35.7 % any biosimilar). Patients receiving either originator short-acting ESAs, long-acting darbepoetin-alfa or M-PEG epoetin-beta had a median DDD consumption of 0.77, 0.81 and 0.90, respectively. Patients receiving a biosimilar short-acting ESA had a median DDD consumption of 0.82. Doses were not increased when the therapy was switched from the originator to the biosimilar ESA. These results were confirmed in 1,886 patients receiving a continuous prescription over 12 accounting quarters, with patients receiving short-acting originator ESAs, long-acting darbepoetin-alfa and biosimilar ESAs having a median daily DDD consumption of 0.80, 0.86 and 0.81, respectively. CONCLUSIONS: We conclude that, based on a population based analysis, ESA consumption of patients on chronic haemodialysis is similar for biosimilar and originator ESAs.
