General practitioners (GPs) who work in occupational medicine (OM) should be trained continuously. However, it seems that ethical issues have been neglected. This cross-sectional study aimed to determine educational priorities for GPs working in OM. A total of 410 GPs who participated in OM seminars were asked to answer a number of questions related to items that they usually come across in their work. The respondents were given scores on 15 items, which pertained to their frequency of experience in OM, their felt needs regarding education in the field, and their knowledge and skills. Ethical issues were the most frequently utilised item and the area in which the felt need for education was the greatest. The knowledge of and skills in ethical issues and matters were the poorest. Ethical principles and confidentiality had the highest calculated educational priority scores. It is necessary to consider ethical issues as an educational priority for GPs working in the field of OM.
