Occupational health nursing is the specialty nursing practice that provides for and delivers health and safety programs and services to workers, worker populations and community groups. The practice focuses on promotion, maintenance and restoration of health, prevention of illness and injury, and protection from work‐related and environmental hazards. Occupational health nurses (OHNs) have a combined knowledge of health and business that they blend with healthcare expertise to balance the requirement for a safe and healthful work environment and a “healthy” bottom line. The most recent data indicate there are approximately 19,000 occupational health nurses who practice in the US and occupational health nurses provide care to workers in countries around the globe. In the U.S. training in OHN is supported by the National Institute for Occupational Safety and Health through the NIOSH Education and Research Centers.
