General practitioners have patients on their lists who work in a variety of occupations, but the doctor is most unlikely to have had any training in occupational medicine. As a result, occupational causes for illness are rarely considered by GPs. Little contact occurs between occupational health physicians and GPs leading to a lack of understanding of the occupational physician's role. These two factors, when combined, may lead to patients receiving sub-optimal treatment. This could be remedied by better undergraduate and postgraduate training, and by greater professional contact.
