Under these circumstances, the U.S. Occupational Safety and Health Administration (OSHA) had published a rule in January 2017, to prevent the development of chronic beryllium disease and lung cancer.

To identify \"high-stress\" workers, the Brief Job Stress Questionnaire (BJSQ) is recommended. According to the stress check program manual issued by the government, high-stress can be defined using two criteria, either the \"sum method\" (simply summing the scores for each scales) or the \"score converted method\" (using converted scores according to the conversion table for each scales). In this study, we examined the differences in results found using these two criteria on \"stress check program\" data.</p><p><strong>Methods: </strong>We used data of 71,422 workers in 117 companies and organizations who conducted stress checks in 2016. The prevalence of high-stress was calculated by applying the two criteria simultaneously, and the chi-square test was used to compare the proportion of workers with high-stress. We subsequently divided participants into the four following groups and calculated the proportion of each group: group A was defined as having high-stress by both criteria; group B, only by the sum method; group C, only by the score converted method; and group D, not defined as high-stress by either criterion. We compared the average values of stress response among four groups using the Kruskal-Wallis test, and further compared the average values between group B and group C using the Bonferroni method.</p><p><strong>Results: </strong>The average age of participants was 43.7 ± 11.1, and 66.8% were males. The proportion of those defined as having high-stress were 11.7% using the sum method and 13.2% using the score converted method; the proportion of high-stress workers was thus significantly higher when using the score converted method (p <.001).

It is an important occupational health issue to support the balance between illness treatment (including nursing care, childcare, etc.) and work. Many patients require mental and financial support to help them with their work-treatment balance. In 2016, the Ministry of Health, Labor and Welfare provided guidelines for supporting employee's work-treatment balance, and in 2018, \"Consulting Fee\" was approved as an insured medical treatment when clinic doctors supported their patients for continuing to work. The request for the consulting fee requires that the clinician and the occupational physician exchange information on the support necessary for the patient to continue working. Generally, occupational physicians obtain medical information from clinicians to give advice on a worker's employment considerations.
