The number of deaths attributable to silica dust exposure among Chinese workers was then calculated using the population attributable risk and the national mortality rate. The population attributable risks were estimated based on the prevalence of workers with silica dust exposure and HRs. Hazard ratios (HRs) for selected causes of death associated with CDE were estimated using the Cox proportional hazards model.

We calculated standardized mortality ratios for underlying causes of death based on Chinese national mortality rates. We estimated the cumulative silica dust exposure (CDE) for each worker by linking work history to a job-exposure matrix. We studied 74,040 workers who worked at 29 metal mines and pottery factories in China for 1 y or more between January 1, 1960, and December 31, 1974, with follow-up until Decem(median follow-up of 33 y).

However, the potential long-term health effects have not been well established across different exposure situations. The Administrative report: National Guidance for doctors assessing workers exposed to respirable crystalline silica dust, with specific reference to the occupational respiratory diseases associated with engineered stone refers to the development of the National Guidance and associated documents to assist medical practitioners identify and assess people at risk of silicosis caused by exposure to respirable crystalline silica dust.Human exposure to silica dust is very common in both working and living environments.

These resources are available to download and print. The National Guidance includes a number of resources to help general practitioners assess workers exposed to respirable crystalline silica dust. The National Guidance Summary (Word 416 KB).The National Guidance Summary (PDF 420 KB).The National Guidance Practice Guide (Word 2730 KB).The National Guidance Practice Guide (PDF 2551 KB).The National Guidance interfaces with, and complements, other existing medical guidelines issued by clinical bodies. It contains the latest research and the best available evidence to help you make informed assessments of at-risk workers. The National Guidance has been developed by medical experts from across a range of relevant fields covering respiratory and thoracic medicine, radiology, environmental and occupational medicine, and work health and safety. The National Guidance covers the most critical components and strategies to support medical practitioners to identify and assess people at risk of silicosis, and to work closely with their patients to improve health outcomes. The recent re-emergence of silicosis is linked to the increasing popularity of engineered stone products, and the processes for cutting, grinding, and polishing this material. The National Guidance for doctors assessing workers exposed to respirable crystalline silica dust ( with specific reference to the occupational respiratory diseases associated with engineered stone) has been developed to help general practitioners identify and assess people at risk of silicosis caused by exposure to respirable crystalline silica dust.
