Abstract
We estimate the extent to which recommendations on the prevention and treatment of migraine issued by professional medical bodies are implemented in medical practice in Germany. Computerized data (MediPlus, IMS Health) were analyzed in 4,636 male and 16,573 female migraineurs from 383 primary care practices 1994 through 1996 (Primary Care of Migraine, PCAOM study). A total of 90,540 drug prescriptions with a documented diagnosis of migraine were issued in 45,669 person-years (1.492 prescriptions [DM 40.99] per person-year to men, 2.109 prescriptions [DM 62.01] per person-year to women). Approximately three of every four prescriptions were incompatible with the recommendations of the German Migraine and Headache Society (DMKG), amounting to extrapolated costs of DM 49 million per year borne by the German statutory health insurance fund for combination migraine preparations. The density of non-DMKG therapies for diagnosed migraine followed a sigmoid curve with increasing patient age, while DMKG-compliant therapies described a bell-shaped curve. Referrals to neurological care specialists were not associated with subsequent primary care focus on recommended therapies. We conclude that medication prescribed for migraine is largely not according to long-standing recommendations by medical societies in Germany.
