To prevent the spread of infection, it is necessary for each individual to adopt infection prevention behavior. We investigated the effect of infection control measures implemented in the workplace on personal infection prevention behavior. We conducted a self-administered questionnaire survey through the Internet from December 22 to 25, 2020, during which period coronavirus disease 2019 (COVID-19) was spreading. Among respondents aged 20 to 65 years (n=27,036), 21,915 workers were included in the analysis. The results showed that as the number of infection control measures in the workplace increased, implementation of infection prevention behavior by individuals also significantly increased. However, the relationship differed depending on the type of personal infection prevention behavior. Specifically, infection control measures against COVID-19 in the workplace may affect personal infection prevention behavior. Implementation of infection control measures in the workplace increases awareness of the importance of individual infection prevention behavior and its implementation by all individuals. These findings may be applicable not only to COVID-19 measures but also to responses to other emerging infections and seasonal influenza.

Objectives: To prevent the spread of coronavirus disease 2019 (COVID-19) infection, it is necessary for each individual to adopt infection prevention behavior. We investigated the effect of infection control measures implemented in the workplace on personal infection prevention behavior. Methods: We conducted a self-administered questionnaire survey through the Internet from December 22 to 25, 2020, during which period COVID-19 was spreading. Among respondents aged 20 to 65 years (n=27,036), a total of 21,915 workers were included in the analysis after excluding self-employed workers (n=2,202), workers in small/home offices (n=377), and agriculture, forestry, and fisheries workers (n=212), etc., whose personal infection prevention behavior was almost the same as infection control measures taken in the workplace. Results: The results showed that as the number of infection control measures in the workplace increased, implementation of infection prevention behavior by individuals also significantly increased. However, the relationship differed depending on the type of personal infection prevention behavior. Specifically, infection control measures against COVID-19 in the workplace may affect personal infection prevention behavior. Conclusion: Implementation of infection control measures in the workplace appears to deepen personal understanding of infection prevention behaviors, and increases awareness of the importance of individual infection prevention behavior and its implementation by all individuals. These findings may be applicable not only to COVID-19 measures but also to responses to other emerging infections and seasonal influenza.

Objectives To elucidate the factors that influence occupational physicians’ decision to issue an employer warning. Methods The interview was conducted with 10 Japan Society for Occupational Health certified occupational physicians (COPs) and certified senior occupational physicians (CSOPs) to create nine fictive scenarios in which an occupational physician may need to consider issuing a warning. Sixteen CSOPs assessed the seriousness of the problem in each of nine scenarios where they may need to consider issuing an employer warning. Next, using a survey questionnaire, 597 COPs and CSOPs were asked to rate how likely they were to issue a warning in each of the nine scenarios, and answer items on their characteristics and number of previously issued warnings. A multilevel logistic regression analysis nested for various scenarios was used to assess the odds ratio (OR) of being likely to issue a warning. Results Valid questionnaires were obtained from 117 participants (19.6%). The ORs and 95% confidence intervals (CIs) were as follows: mean score of seriousness of the problem, 5.90 (4.50‐7.75); years of experience as occupational physician, 1.04 (1.02‐1.06); women, 1.75 (1.20‐2.54); being a part‐time occupational physician without in‐house experience, 2.08 (1.31‐3.29); and having previously issued two or more times warnings, 1.99 (1.29‐3.06), compared with those who had never issued a warning. Conclusions Occupational physicians’ likelihood to issue a warning was associated with the seriousness of the problem as assessed in various scenarios, years of experience as occupational physician, gender, employment type, experience as in‐house occupational physician, and number of past warnings.

Background The COVID-19 pandemic has had various impacts on businesses and workers. Occupational physicians (OPs) are expected to actively support employers' efforts to minimize the damage of the pandemic. However, there is little research on the role of these specialists during a pandemic. Clarification of the contributions of OPs to workplace health in the COVID-19 pandemic will be of value so that they can be effectively deployed the next time a similar significant emergency affects a large population. Methods We employed semi-structured interviews and qualitative content analysis of the interview transcripts. Twenty OPs were selected as priority candidates from among 600 OPs certificated of the JSOH, and thirteen who met the eligibility criteria agreed to participate. We extracted meaning units (MUs) from interview transcripts according to the research question: "What was the role of OP in the COVID-19 pandemic?" and condensed and categorized them. Results A total of 503 MUs were extracted from the transcripts. These were abstracted into 10 condensed MUs and two categories. Categories 1 and 2 dealt with “Role in confronting the direct effects of the pandemic” and “Role in confronting the indirect effects of the pandemic” and accounted for 434 (86.3%) and 69 (13.7%) MUs, respectively. Conclusion This study identified the role of OPs in Japan in the COVID-19 pandemic. The results showed that they made a wide range of contributions to the direct and indirect effects of the pandemic. We hope our findings will help OPs during future pandemics or other long-term emergency situations.

Background The coronavirus disease 2019 (COVID-19) pandemic has had various impacts on businesses and workers worldwide. The spread of infection has been reported through cluster outbreaks in the workplace, and World Health Organization has emphasized workplace infection control measures. Occupational physicians (OPs) are expected to actively support employers’ efforts to minimize the damage of the pandemic. However, there is little research on the role of these specialists during a pandemic. Clarification of the contributions of OPs to health and safety at the workplace in the COVID-19 pandemic would be beneficial to ensure that OPs can be effectively deployed in the next pandemic. Methods We employed semi-structured interviews and qualitative content analysis of the interview transcripts. Twenty OPs were selected as priority candidates from among 600 OPs certificated of the JSOH, and thirteen who met the eligibility criteria agreed to participate. The online interviews were conducted in November and December 2020 with thirteen OPs. We extracted meaning units (MUs) from interview transcripts according to the research question: “What was the role of OP in the COVID-19 pandemic?“ and condensed and abstracted them into codes and categorized them. Validity was confirmed by additional 5 OPs interviews. Results A total of 503 MUs were extracted from the transcripts. These were abstracted into 10 sub-categories and two categories. Categories 1 and 2 dealt with “Role in confronting the direct effects of the pandemic” and “Role in confronting the indirect effects of the pandemic” and accounted for 434 (86.3%) and 69 (13.7%) MUs, respectively. These results were validated by another 5 interviews. Conclusion This study identified the role of OPs in Japan in the COVID-19 pandemic. The results showed that they made a wide range of contributions to the direct and indirect effects of the pandemic. We hope our findings will help OPs during future pandemics or other long-term emergency situations.
