Summary of the article

In this letter to the editor, the authors responded to an editorial by Susan Peters that had described the strengths and limitations of job-exposure matrices (JEM) in occupational epidemiology research. They argued that JEM may also be useful in compensation and surveillance in occupational health. In compensation, JEM could support the assessment of exposures relevant to specific health conditions. They cited work examining a JEM as a decision tool for compensating work-related musculoskeletal disorders. Because occupational diseases are often under-recognized, they suggested that JEM could be used to screen for occupational exposures as part of health surveillance. They noted that using JEM to screen for asbestos and wood dust exposure in the clinical setting had shown promising results. JEM could also help policy-makers set priorities and help practitioners target prevention and exposure measurement. The authors described the JEMINI (JEM InterNatIonal) initiative, which began with physical (biomechanical) exposures and had started homogenizing job coding systems and comparing available JEM. They cautioned that estimating differences in exposure between countries would require much more work, without guaranteed success. The limitations they listed were the source of exposure data, job coding that is time-consuming and error-prone, and job-level averages that lose individual variation. They concluded that JEM cannot replace professionals in individual exposure assessment but might be used as a public health tool, provided their limitations are properly taken into account.

In plain English

This is a letter to the editor, not a research study, and it reports no new data. Responding to an editorial by Dr Susan Peters on job-exposure matrices (JEM) in occupational epidemiology research, the authors argued that JEM might also help with compensation and occupational health surveillance. JEM are tools that summarize exposures at the level of a job and reflect an average exposure within that job. Citing earlier studies rather than findings of their own, the authors wrote that using JEM to screen for asbestos and wood dust exposure in clinical settings had shown promising results. They described the JEMINI initiative, an effort to explore international JEM that could be used across countries, which began with physical (biomechanical) exposures. The authors noted limitations. Coding occupations is time consuming and can introduce error, and JEM give an average exposure at the expense of individual variation. In clinical or compensation settings, they wrote, JEM cannot replace the professionals who assess exposure. The authors concluded that JEM developed for research might also be used as a public health tool, provided their limitations are properly taken into account.

What the study did and found

• Design: Letter to the editor (commentary responding to an editorial); no original data
• Exposure: No exposure was studied directly. The letter discusses job-exposure matrices in general. It mentions screening for asbestos and wood dust exposure only by citing earlier studies (references 4 to 6).
• Main results:
  • Not a study finding: the authors argued that JEM may also be useful in compensation and occupational health surveillance, beyond research.
  • Not a finding of this letter: the authors cited earlier studies reporting that using JEM to screen for asbestos and wood dust exposure in the clinical setting had shown promising results.
  • The authors described the JEMINI initiative, which explores international JEM. It began with physical (biomechanical) exposures and has started homogenizing job coding systems.
• The authors' conclusion: The authors concluded that JEM developed for research might also be used as a public health tool, provided their limitations are properly taken into account.
• Limitations the authors state:
  • Limitation of JEM stated by the authors: coding occupations is time consuming and can introduce error.
  • Limitation of JEM stated by the authors: JEM reflect an average exposure within a job and miss individual variation.
  • Limitation stated by the authors: in clinical or compensation settings, JEM cannot replace professionals who assess exposure.
  • Limitation stated by the authors: estimating differences in exposure levels between countries will require much more work, with no guaranteed success.
