General practitioners (GPs) are responsible for 70% (or roughly 30 billion DM) of the entire medication prescribed by practising doctors. Pharmacotherapy circles (PTC) are a further education, which focuses on the optimisation of prescription behaviour (best therapy possible in clinical pharmacology, the translatability into daily practice and guides the concept and contents of the further education. The concept of further education in pharmacotherapy circles developed by us follows the rules of quality assurance in medical care:
Assessment: Recording prescriptions in one quarter for evaluation of prescription problems. Problem selection: Medicine groups, whose prescription frequency give an indication of prescription quality, i.e. vein and rheumatism ointments (as little as possible) and proton pump inhibitors and lipid reducers (as many as necessary). The problem analysis takes place as peer review by a group of physicians from the same field, and under the moderation of two doctors from the same field, who have been for at last one year, carefully instructed, in pharmacology and the moderations of groups. The formulation of guidelines shall be shown for an indication area, for which there is no robust therapy (e.g. venous medicaments). The purpose of theses guidelines shall be to optimise the treatment, strengthen the health consciousness of the patient and reduce the prescription of medicaments, whose efficacy has not been proven. The evaluation proves that these goals have been reached. The total reduction in costs is different for individual physicians depending on the original prescription level of the underlying medicament costs. Only the third of "high prescribers" showed economy reserves. There were savings in medicaments with non-proven efficacy among the lower and middle prescribers, however, there were increased expenditures and therapy improvements in other areas.
