In the occupational health system, some hospitals have assigned their directors or board chairpersons as occupational physicians, thereby raising regulatory concerns. Only 85% of the hospitals held monthly health committee meetings, whereas 98% had a health committee in place. Workplace rounds were conducted more frequently in hospitals with more beds and were conducted regularly in 79% of the hospitals. Hospitals with more beds also received more occupational nurse participation. Infection control measures, including immune screening and vaccination for hepatitis B and rubella/measles, have been widely implemented. All hospitals administered COVID-19 vaccinations to staff members. Many hospitals have established consultation systems for occupational physicians on mental health initiatives; however, return-to-work interviews conducted by occupational physicians were significantly more common in hospitals with more beds, with statistical significance. Regarding doctors' workstyle reforms, hospitals with more beds were less likely to obtain Level A certification and more likely to obtain Level B or C certification.

Organizations continue to face significant challenges to support employees in safely returning to work after mental health-related leaves and to ensure long-term stability without relapse. This literature-based study was performed to clarify support skills that occupational health nurses employ to facilitate return to work for employees with mental health issues.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A literature search of the Medical Central Journal Web Edition (ver. 5) was conducted using the keywords \"Occupational Health Nurses\" AND (\"mental health\" OR \"mental health issues\" OR \"mental well-being\" OR \"mental illness\" OR \"depression\" OR \"depressive symptoms\"), in combination with (\"return-to-work support\" OR \"return-to-work\" OR \"workplace reintegration support\" OR \"workplace reintegration assistance\"). Conference proceedings were excluded. No restrictions were placed on publication year. Two original articles and ten review articles were selected for analysis. Support skills used by occupational health nurses to support workplace reintegration were identified, grouped by target recipients (e.g., workers, family members, supervisors, and human resources), and placed into subcategories and overarching categories.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Four main categories of support skills used by occupational health nurses to facilitate workplace reintegration were identified.• Support for patients to recover from illness and overcome challenges• Creating a healing environment and coordinating interactions with family and workplace• Comprehensive information gathering and assessment of whether recovery status will permit workplace reintegration• Establishing a tailored follow-up system post-reintegration based on worker and workplace needs and circumstancesDiscussion and Conclusions: Occupational health nurses support employees by helping them recognize personal challenges and build stress resilience through \"supporting patient recovery from illness and helping patients overcome challenges\". They utilize \"thorough information gathering and assessment of recovery status for workplace reintegration\" to reduce the likelihood of relapse. The support skills identified in this study were highly individualized and varied to meet the specific needs of each worker. The reviewed literature contained extensive occupation-relevant descriptions and numerous documents introducing the authors' initiatives, suggesting that these authors are experienced occupational health nurses. It remains unclear how consistently these support skills are applied and what impact years of experience or workplace environment exert on consistency.

This survey examined their experiences in proposing workplace environment improvements, their knowledge of participatory workplace environmental improvement programs, and their experience in proposing and introducing such programs. It also assessed the facilitators and barriers to the introduction and implementation of such programs. Respondents who had proposed such a program to their client companies were asked to connect the research team with the individual responsible for workplace environmental improvement at those companies. After obtaining consent, we interviewed these individuals in November and December 2023 to explore the facilitators and barriers to introducing participatory workplace environmental improvement programs. The questionnaire and interview data were analyzed using the occupational health version of the Consolidated Framework for Implementation Research (CFIR), and implementation strategies were developed with reference to expert recommendations for implementing change (ERIC).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Result: &lt;/strong&gt;We received 57 responses overall. Of the 49 respondents who were familiar with participatory workplace environmental improvement programs, 33 (67.8%) had proposed them.

Responses from 143 institutions that provided valid data and consent were obtained and analyzed. The survey assessed the structure of the radiation management system (comprising five elements), verification status and management of radiation workers, and implementation of awareness-raising activities regarding proper personal dosimeter use. Each questionnaire item was analyzed using descriptive statistics and chi-squared tests. To determine the optimal sequence for implementing the five elements of the radiation management system, correlation, logistic regression, decision tree (CART), and path analyses were conducted.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Among the 143 institutions, 46.9% had established a radiation exposure management organization (e.g., a committee), and 55.9% had administrators who clarified radiation management policies and guidelines. Regarding radiation workers, only 32.6% of radiation management personnel were aware of whether their institution's radiation workers were also engaged in radiation work at other facilities (referred to as \"dual employment\"), whereas 35.0% were aware of confirmed cases of employees from other institution receiving dual employment. Additionally, 33.6% of the institutions did not conduct sufficient awareness-raising activities regarding proper personal dosimeter use. A comparison between clinics and hospitals revealed that Occupational Safety and Health Management Systems (OSHMS) were more widely implemented in clinics than in hospitals. Additionally, clinics demonstrated a better understanding of whether radiation workers were engaged in dual employment compared to hospitals. The establishment of a radiation exposure management organization was found to be crucial for building a radiation management framework.
