The IOMSC is a medical and scientific organization that provides an assembly for representatives of occupational and environmental medicine societies worldwide to:

  • Address and collaborate on issues of concern and opportunities;

  • Advance the specialty of occupational and environmental medicine; and

  • Promote the provision of evidence-based occupational medicine.

We do this by:

  • Serving as a model/leader for OM societies worldwide by fostering and providing opportunities to gain and enhance the knowledge and expertise required of OEM physicians.

  • Providing tools and resources to emerging OEM societies to educate their members which will enhance the level of OEM care worldwide.

  • Practicing by what has been proven to work.

  • Efficacy through information that is more applicable to large groups and provides the ability to reach all global regions with more effective OEM care.

In 2012, leaders in the United States’ American College of Occupational and Environmental Medicine (ACOEM) and the United Kingdom’s Society of Occupational Medicine (SOM) began discussing an initiative designed to build stronger collaborative relationships between occupational medical societies around the world that represent the physicians and other health professionals who promote the health of workers. These discussions were driven by a growing awareness that occupational medicine societies worldwide are addressing a common set of issues as work processes become more standardized, businesses become global, and environmental hazards in the workplace and health risks among workers increasingly cross national boundaries. In a series of meetings, ACOEM and SOM created the framework for a new organization, the International Occupational Medicine Society Collaborative (IOMSC).

On May 1, 2013, the two organizations convened leaders from 18 national occupational medical societies to discuss mutual issues and concerns in global occupational medicine, a meeting that led to the establishment of the IOMSC. As established, the IOMSC provides an ongoing assembly to promote best practices in occupational medicine and greater awareness of issues and solutions for better worker health worldwide. Its active participants are delegates appointed by occupational medical organizations, world over, including nations with developing economies. IOMSC works through the societies’ physician members to reach corporations and governments around the world. Since its inception in 2013, the IOMSC has steadily grown from the initial group of 18 societies in 16 countries to a roster that today includes 45 societies in 41 countries.
