... eporting by occupational health physicians and structured and transparent assessment by occupational health experts. A new work-related health risk is defined as a work-related disease due to specific exposure in a specific work setting not described in the literature before. Results The online reporting and assessment tool proved to be a feasible means of reporting possible new combinations of health problems and exposures in the work situation. Eleven of the 15 cases reported until October 2014 were fully assessed: one was an entirely new work-related disease, four were known but uncommon work-related diseases, five were known but new in the reported work situation and one was a well-known work-related disease. Conclusions An online reporting system used in an occupational health setting can provide insight into new workrelated health risks by creating a structured way to gather, report and assess new combinations of health problems and exposure in the workplace.
