Assessment of a three-year experience with a Belgian Primary Care data Network.

The paper describes the experiences with a Belgian Primary Care data Network from 1999 till 2002. Three cycles of data collection have been performed. The network involves about 300 general practitioners (GPs) and up to 8 different software packages. This network is semi-anonymous, semi-automatic and mixed (paper and electronic with various software's). For the coming next years, efforts should be focused on solving some frequently occurring problems with the data collection through the EPR, such as a considerable number of data lacking and the fact that GPs do not always use the problem oriented structure of the EPR (Electronic Patient Record). Afterwards, more promising usage could be considered and developed such as repeated data collection using a same GPs' sample, long-term recording studies, usage of larger GPs' samples, etc.
