Study hypothesis

Participation of general practitioners in quality circles on rational prescribing, including feedback of prescribing data, leads to improvement prescribing of performance.

Ethics approval

The trial is aimed at implementing evidence-based guidelines into general practice. The intervention is based on peer review groups for GPs, evidence based guidelines and individual feedback of prescription data to the GPs. In Germany, by the Social Code Book (SGB V) both the regional associations of statutory sick fund doctors (KV) and the regional statutory sick funds like the VdAK/AEV Hesse are obliged to inform doctors about prescribing and to support them about the use of prescription budgets. In this trial we tried to optimise implementation of what is already asked by the law and measure the effect against a control group.

In a contract signed on August 3rd, 2001, between the VdAK/AEV Hesse, the KV Hesse (which both are statutory legal institutions) and the research institute it is formulated that the regulations of the law about data protection and protection of patients are to be followed by all partners. A data approval committee of the KV and the VdaK/AEV Hesse gave positive approval of the contract before it was signed.
