WHOThe World Health Organization (WHO) and International Labour Organization (ILO) are currently developing a joint methodology for estimating the burden of work-related disease and injury (“joint methodology”). The joint methodology will allow estimation of exposures to occupational risk factors and, in turn, estimation of the numbers of deaths and disability adjusted life years attributable to these occupational exposures. It will enable the organizations to regularly produce joint WHO/ILO estimates of occupational risk factor exposures and of the work-related burden of disease and injury from global to national level, by sex and age.

For the joint methodology, WHO and ILO have built a dedicated global database of exposures to occupational risk factors, and this database will be regularly updated with additional official data becoming available. The data in the global database, together with additional data sourced through 14 systematic reviews being conducted in parallel, will be modelled to estimate the proportions of national populations that are exposed to the occupational risk factors of interest. For this exposure modelling, existing and established statistical models will be applied and further developed. Once the global health estimates of exposures to occupational risk factors have been produced, they will be used to populate statistical models of the work-related burden of disease and injury due to these occupational exposures. Established statistical models for estimating the burden of disease will be applied and may be further developed.

The statistical estimation methodologies and final global health estimates for occupational risk factor exposures and their attributable work-related burden of disease and injury will be published in a technical report and in a series of academic journal articles. WHO, in collaboration with ILO, is seeking a Consultant “Statistical modeller, work-related burden of disease” for this project.
