Occupational and environmental medicine focuses on the interactions between work, health and the environment. Doctors who specialize in this field prevent, evaluate, and manage adverse health effects from work and environmental hazards. Individuals can be exposed to chemicals, sources of traumatic injury, occupational diseases, and hazardous physical agents in their jobs. Any of these exposures can cause injury or disease, which can occur immediately or even after years or decades. Understanding these issues and their effects constitutes the core of occupational medicine.
MISSION: REOH specializes in evidence based medical reviews of injuries and illnesses related to work and the environment.
VISION: REOH will be the top source of occupational and environmental health services.
