[Analysis of occupational health activities through classifying reports from medical facilities in Japan]

The objectives of this study were to analyze current trends in occupational health activities by classifying reports from medical facilities in Japan.

Reports of current workplace-level occupational health activities from medical activities that were collected by the Japan Medical Association Occupational Health Committee were used for the study. Of 5,000 questionnaire forms sent to medical facilities, 1,920 responses were returned. The freely described reports on ongoing occupational health activities contained in these responses were classified according to each of the following aspects of reported activities: 1) details of occupational health activities including main actors in workplace-level actions; and 2) approaches taken for occupational safety and health. The classification of the reports was implemented by a working group comprising selected occupational health practitioners and researchers.

Among 1,920 survey responses, 581 valid texts were analyzed. Altogether, 1,044 occupational health activities currently undertaken by the facilities were extracted. The reported activities that were classified according to details of occupational health activities mainly comprised "Measures for preventing overwork, labor management, and work-style reform" (35.7%), "Measures for improving mental health" (21.0%), and "Review of occupational safety and health management systems" (19.3%). Medical facilities implementing "Measures for mental health" alongside "Measures for preventing overwork, labor management, and work-style reform" were reported in 13.2% of the responding medical facilities. "Occupational health professionals or safety and health management staff" (71.7%) were the most frequent main actors of these activities, followed by "Members of the workplace" (18.4%) and "Outsourced experts" (2.4%). "Comprehensive safety and health management" (42.0%) was the most common approach taken for occupational safety and health, followed by "Management focusing on topics" (23.8%) and "Case management" (16.5%). Most of these activities focused on primary prevention aimed at labor management including prevention of overwork, work-style reform, and mental health promotion. Another key trend could be "Teamwork among occupational safety and health staff, workers, and employers at respective workplaces as well as outsourced experts."

Several key trends were extracted from current occupational health activities at medical facilities. In most cases, these measures were implemented simultaneously. This suggests the importance of combining primary prevention measures for mental health with measures for labor management including prevention of overwork. These activities reflect emerging trends that incorporate teamwork between experts, workers, and employers, and provide new perspectives on workplace-level occupational safety and health activities.
