[Clinical trials in general practice. The telematics solution]

Clinical trials with private practitioners pose a series of specific problems. Among them, the large number of investigators, the scarcity of time that each investigator can allocate to the study, may be eased by using computerized network.

Central randomization, on line data editing, immediate personalized patient following schedule are helpful by products. Experience of several years is described.
