Objectives: This study clarified the competencies of occupational health nurses necessary to obtain agreement on health policies from corporate decision-makers and from those in a position to influence health policy decisions (hereafter referred to as “key persons”). Methods: This study employed the Delphi method using a Web-based survey. The draft competency items were developed through a literature review, semi-structured interviews with relevant personnel, and discussions among the researchers. The survey was conducted twice from October to November 2021. The participants were 17 occupational health nurses, 6 university faculty members involved in occupational health nursing education and research, and 5 key persons in companies. Results: Based on the agreement rate and opinions of each item in the two surveys, the final competencies were found to be in 35 items in 8 categories, which were reviewed by the researchers. Conclusion: Although some of the items were similar to those listed in previous studies, competency items were selected specifically for occupational health nurses involved in the health policy decision-making process.

Objective: To clarify how occupational health nurses implement sleep health guidance to prevent and treat lifestyle-related diseases and explore factors affecting its implementation. Methods: A questionnaire was administered to 895 members of Japan Academy of Occupational Nursing and Japan Society for Occupational Health, Expert Community of Occupational Health Nursing, who were employed at various facilities. After univariate analysis, the relevant items were analyzed using logistic regression. Result: Of the 895 members, only 27.3% responded to the questionnaire, indicating a valid response rate of 26.8%. Although 98.7% of the respondents believed that sleep health guidance was “necessary” or “somewhat necessary,” only 59.2% of them provided it to the employees. Participation in training sessions and using an original sleep health guidance manual were among the six items that were significantly correlated with sleep health guidance implementation. Conclusion: Although most respondents recognized the importance of sleep health guidance, only approximately 60% of them implemented it. This finding highlights the need for improved organizational support and opportunities for self-improvement among occupational health nurses.
