The purpose of the study was to evaluate general practitioners' (GPs') interest in CME. A medical audit comprising 369 GPs in three counties was conducted in 1996. During 28,550 consultations the participating GPs recorded clinical subject, handling of the consultation, problems in the consultation and perceived need for training in relation to the consultation. The interest in CME varied from GP to GP and from one clinical subject to another. Desire for CME was expressed in relation to 16% of the consultations, most frequently in relation to psychiatry, community medicine and musculoskeletal diseases. Theoretical courses were the learning style most often preferred, especially for subjects requiring biomedical knowledge. Newer educational methods were also listed. Organisers of CME for general practitioners should be aware of the wide range of needs and wishes for CME among general practitioners.
