The present situation and the future needs in training of occupational health personnel were studied in a consultation held by the Regional Office for Europe of the World Health Organization together with the Government of Yugoslavia. Approaches to training were reviewed for these countries: Bulgaria, Finland, the Federal Republic of Germany, Hungary, Italy, Norway, Poland, Sweden, the Union of Soviet Socialist Republics, the United Kingdom, Yugoslavia, and some other member states of the European community. Attention was also given to problems in occupational health that have arisen from new technological developments (psychological stresses, use of dangerous pathogens and new physical agents in research and production) and from new biological knowledge (undefinable thresholds to exposure to various substances and risk of teratogenicity). New requirements for training that were recommended included both multidisciplinary and interdisciplinary training in occupational health and practical training. Some conclusions were that occupational health specialists must become more specialized, that the value of many routine medical tests should be questioned, that practitioners of occupational medicine must be competent in clinical medicine, that an enormous need exists for development in the field of mental health, and that communication training is needed.
