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.

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. Of those with the proposed experience, 11 (33.3%) reported successful implementation. Interviews were conducted with representatives from two workplaces that implemented the program after receiving a proposal from their occupational health physicians and one that had yet to implement it. The analysis identified \"Relative Advantage, Tension for Change,\" and \"Implementation Climate\" as high-priority facilitators and barriers during the Pre-Proposal Internal Setting phase. During the proposal, additional factors such as \"trialability,\" \"formally appointed internal implementation leaders,\" \"self-efficacy,\" and \"relative priority\" were extracted.

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.
