This lecture on strategic thinking in occupational public health stressed that attention must be directed toward the prevention of occupational diseases and injuries through an organized community effort. According to the speaker, such an aim encompasses the various disciplines involved in occupational medicine, safety, and nursing to include such avenues as clinical and social medicine and general public-health practice. A summary was offered of the development of public health and occupational health in the United States, as it grew from the level of state and local responsibility to become a concern of the Federal Government. Occupational medicine also grew at the business sector level with surgical services being established for injured workers at the job site and concerns over toxic exposures growing. The passage of the Occupational Safety and Health Act of 1970 is discussed along with a brief review of new Federal agencies formed by the act. New efforts are being directed at hazard identification and risk assessment, and also at controlling the exposures through preventive or protective measures. Additional efforts are currently being made in the educational field.
