Each year in the United States, more than 4,000 occupational fatalities and more than 3 million occupational injuries occur along with more than 160,000 cases of occupational illnesses. Incorporating patients'' occupational information into electronic health records (EHRs) could lead to more informed clinical diagnosis and treatment plans as well as more effective policies, interventions, and prevention strategies to improve the overall health of the working population. At the request of the National Institute for Occupational Safety and Health, the IOM appointed a committee to examine the rationale and feasibility of incorporating occupational information in patients'' EHRs. The IOM concluded that three data elements - occupation, industry, and work-relatedness - were ready for immediate focus, and made recommendations on moving forward efforts to incorporate these elements into EHRs.
