Occupational Health Doctors visit workplaces and assess a range of work-related health issues. Preventing illness and injuries that can occur as a result of work are an important aspect of occupational medicine, as well as rehabilitation following illness or injury. An OHP oversees maintenance of case histories, health examination reports, and other medical records. They formulate and administer workers health programs, inspect plants and make recommendations regarding sanitation and elimination of health hazards. Most occupational physicians are engaged in private practice or in-plant services.
