[Prescription of TNF-alpha inhibitors and regional differences in 2010].

Tumor necrosis factor alpha (TNF-α) inhibitors are an important treatment option for rheumatoid arthritis and other chronic inflammatory diseases. However, attention should be paid to severe adverse drug reactions and very high costs of therapy. The objective of this study was to examine the prescription and costs of TNF-α inhibitors as well as regional differences at the district level in Germany. For this purpose, prescription claims data of a German health fund with 9.1 million insured persons from the year 2010 were analyzed. A total of 45,229 packs (0.1% of all prescribed drugs) and 3.15 million defined daily doses (DDD) of TNF-α inhibitors were prescribed. This leads to a total pharmacy revenue of 163.18 million Euro (share 4.1%) and 1 DDD costs on average 51.61 Euro. For 10,078 patients at least one TNF inhibitor was prescribed (prescription prevalence 111 per 100,000) with a higher proportion of women (125 vs. 92 per 100,000). The average revenue per insured person was often higher in districts of eastern Germany (>30 Euro) for reasons unknown. Provided that use is appropriate to indications there are only low saving potentials.
