Still Unanswered Questions About SARS-CoV-2 Mortality and Future Directions for Occupational Medicine.

The article discusses a recent study on mortality attributable to COVID-19 in Italy and the need for further analysis. The study used a reliable methodology to estimate excess deaths due to the pandemic. However, there are still questions about the specific effects of COVID-19 compared to other factors, such as delayed or missing access to treatment for other illnesses. Analyzing the time course of excess deaths could reveal such effects. There are also open questions about how COVID-19 deaths are classified and reported, which could lead to over or under-diagnosing cases. The article notes that occupational physicians have played an important role in preventing the spread of COVID-19 among workers. A recent study found that personal protective equipment (PPE), particularly masks, effectively reduced the risk of infection among healthcare workers. However, it is still unclear whether Occupational Medicine should incorporate infectious diseases as a major concern or return to its historically agnostic attitude toward communicable diseases. More data on mortality from specific diseases will be needed for further analysis and understanding of the pandemic's effects on mortality rates in Italy.

Hospital infection control and occupational medicine services in the face of the COVID-19 pandemic in occupational health / Serviços de controle de infecção hospitalar e de medicina do trabalho no enfrentamento à pandemia de COVID-19 na saúde ocupacional

In this article, the actions developed by the Hospital Infection Control Service (HICS) and Occupational Medicine (OM) to face the COVID-19 pandemic and track cases of infection among employees of a large hospital in Belo Horizonte, Minas Gerais, Brazil. Training actions, guidelines on how to collect a swab sample, Code 19 (COVID-19) simulation, dressing/undressing, hand hygiene, the definition of flows, and the quantification of cases infected by COVID-19 among employees in care areas were highlighted. The engagement of HICS and OM in the prevention and promotion of health were fundamental to facing the pandemic. It is estimated that SARS-CoV-2 infection rates among staff at the study hospital were similar to those at other hospitals. The experience report is important for expanding knowledge about action planning in the context of a large hospital (AU).

Sleep in Residents: A Comparison between Anesthesiology and Occupational Medicine Interns.

Sleep deprivation is a significant risk to the health and judgment of physicians. We wanted to investigate whether anesthesiology residents (ARs) who work only one night shift per week have different physical and mental health from occupational medicine residents (OMRs) who do not work at night. A total of 21 ARs and 16 OMRs attending a university general hospital were asked to wear an actigraph to record sleep duration, heart rate and step count and to complete a questionnaire for the assessment of sleep quality, sleepiness, fatigue, occupational stress, anxiety, depression and happiness. ARs had shorter sleep duration than OMRs; on average, they slept 1 h and 20 min less (p < 0.001). ARs also had greater daytime sleepiness, a higher heart rate and lower happiness than OMRs. These results should be interpreted with caution given the cross-sectional nature of the study and the small sample size, but they are an incentive to promote sleep hygiene among residents.

[Directions of organizational and economic changes in occupational health services as a response to the COVID-19 pandemic - challenges to the health crises]. / Kierunki organizacyjno-ekonomicznych zmian ochrony zdrowia nad osobami pracujacymi jako odpowiedz na pandemie COVID-19 ­ wyzwania wobec kryzysów zdrowotnych.

The COVID-19 pandemic caused not only short-term organizational and economic changes in the functioning of occupational health services, but also enforced to include them in the formulation of a strategic systemic approach to this link of the health care system. The aim of the article is to identify and describe the organizational and economic changes in occupational health services during the pandemic. On this basis, the directions of further research on the improvement of the activities of health care entities of working people in response to future health crises have been formulated. The review covered legal acts relating to organizational and economic changes, Polish and foreign expert publications, full-text Polish and English-language scientific articles included in the PubMed database, publications beyond the specified period, consistent and useful in explaining the concepts of organization, management and economics. The changes in occupational health services presented in the literature during the pandemic consisted of: introducing additional organizational forms of providing health care to employees including occupational medicine leaders, strengthening supervision over working conditions, interdisciplinary cooperation for managing the health of working people, participation in pro-vaccination campaigns, activities in the field of rehabilitation after COVID-19 and new-quality cooperation with public and private health stakeholders. As the result of the review, problems were formulated for future research, which included ensuring the security of occupational medicine entities in terms of resource availability, adjusting the allocation of resources to new financial needs during and after a pandemic, evaluation of organizational and economic changes introduced during the pandemic and the legitimacy of their maintenance in subsequent periods, the development of economic and organizational instruments for the time of crisis, the scope and principles of cooperation with health care stakeholders and the introduction of medical technologies based on a medical and economic assessment according to Health Technology Assessment.

Singleplex, multiplex and pooled sample real-time RT-PCR assays for detection of SARS-CoV-2 in an occupational medicine setting.

For workplaces which cannot operate as telework or remotely, there is a critical need for routine occupational SARS-CoV-2 diagnostic testing. Although diagnostic tests including the CDC 2019-Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel (CDC Diagnostic Panel) (EUA200001) were made available early in the pandemic, resource scarcity and high demand for reagents and equipment necessitated priority of symptomatic patients. There is a clearly defined need for flexible testing methodologies and strategies with rapid turnaround of results for (1) symptomatic, (2) asymptomatic with high-risk exposures and (3) asymptomatic populations without preexisting conditions for routine screening to address the needs of an on-site work force. We developed a distinct SARS-CoV-2 diagnostic assay based on the original CDC Diagnostic Panel (EUA200001), yet, with minimum overlap for currently employed reagents to eliminate direct competition for limited resources. As the pandemic progressed with testing loads increasing, we modified the assay to include 5-sample pooling and amplicon target multiplexing. Analytical sensitivity of the pooled and multiplexed assays was rigorously tested with contrived positive samples in realistic patient backgrounds. Assay performance was determined with clinical samples previously assessed with an FDA authorized assay. Throughout the pandemic we successfully tested symptomatic, known contact and travelers within our occupational population with a ~ 24-48-h turnaround time to limit the spread of COVID-19 in the workplace. Our singleplex assay had a detection limit of 31.25 copies per reaction. The three-color multiplexed assay maintained similar sensitivity to the singleplex assay, while tripling the throughput. The pooling assay further increased the throughput to five-fold the singleplex assay, albeit with a subtle loss of sensitivity. We subsequently developed a hybrid 'multiplex-pooled' strategy to testing to address the need for both rapid analysis of samples from personnel at high risk of COVID infection and routine screening. Herein, our SARS-CoV-2 assays specifically address the needs of occupational healthcare for both rapid analysis of personnel at high-risk of infection and routine screening that is essential for controlling COVID-19 disease transmission. In addition to SARS-CoV-2 and COVID-19, this work demonstrates successful flexible assays developments and deployments with implications for emerging highly transmissible diseases and future pandemics.

Changing Attitudes towards Occupational Medicine with Blended Learning Methods Is Possible among Medical Students in Spain: A Longitudinal Study.

Medical students generally express a low interest in Occupational Medicine. We aimed to assess the attitudes and changes in attitudes of students towards this area after completing a course on Occupational Medicine in two Medical Universities in Spain (Zaragoza and Castilla-La Mancha). The teaching method included blended learning as a model that used online virtual patient platforms (CASUS) and/or EMUTOM, as well as traditional methods such as face-to-face teaching. A total of 526 students (98 of whom attended the University of Castilla-La Mancha) participated during three academic years (2015-2016, 2016-2017 and 2017-2018). The validation of the questionnaire was carried out using reliability, exploratory and confirmatory factor analysis. For the analysis of internal consistency and discrimination, Cronbach's alpha was used. The adequacy of the factor analysis was measured by means of KMO, and a correlation matrix was examined by means of Bartlett's test of sphericity. To identify differences between students before and after completing the course, the Mann-Whitney U-test for independent samples was used. Our results show that despite a negative or neutral attitude towards Occupational Medicine, the acquisition of competences and skills in this area and their training were recognized as fundamental for their future professional performance as doctors in any specialty.

Quarantine and Mental Health Challenges for Occupational Medicine: The Case Report of a Nurse Infected With SARS-CoV-2.

This case study draws attention to the psychosocial difficulties that emerged in the context of the coronavirus disease 2019 (COVID-19) outbreak in relation to the remote management of subjects with psychiatric vulnerabilities following exposure to prolonged quarantine. The case involves a 56-year-old hospital nurse, followed by the Occupational Health Department of a major university hospital in central Italy for mood instability in the context of a cyclothymic temperament. She was quarantined for occupationally acquired COVID-19 and remained positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via swab test for more than 2 months between March and May 2020. In this case study, we discuss the challenges presented by the risk of a prolonged quarantine in a psychologically vulnerable employee, the need for occupational medicine to provide adequate health surveillance of all health care workers during the COVID-19 pandemic, the effectiveness of telepsychiatry, and the difficulties in formulating a proper treatment strategy.

[COVID-19 immunizations in occupational medicine]. / Szczepienia przeciwko COVID-19 w medycynie pracy.

This article discusses issues related to exposure to SARS-CoV-2 in the work environment and employee's vaccination against COVID-19. The new SARS-CoV-2 coronavirus identified as the etiologic agent of COVID-19 prompted the World Health Organization (WHO) to declare a pandemic in March 2020. The droplet route transmits the virus. Therefore, health care workers in contact with sick people and anyone employed in direct contact with large numbers of people are particularly vulnerable to infection. The introduction of COVID-19 vaccination removes the need for quarantine, reduces the risk of disease, limits transmission within the workplace, and reduces sickness absence. The role of the occupational health services is to promote vaccination against COVID-19 by providing reliable information on the safety and efficacy of immunization and organizing and carrying out vaccination in workplaces.

Procedural aspects of COVID-19 vaccinations for seafarers on ocean-going vessels.

The increasing availability of safe and authorised coronavirus disease 2019 (COVID-19) vaccines for the first time provides the opportunity to vaccinate seafarers on board their ships while in port. Speedy vaccination of seafarers secures their health and serves to avoid the international propagation of COVID-19 virus variants via maritime traffic. As a port medical clinic, we will share our practical vaccination experience on board of merchant vessels in German/European ports with our esteemed coastal colleagues to stimulate their participation in this endeavour. You will have to adapt the procedure to your national particularities, otherwise please freely share the information with interested parties. Detailed guidance on COVID-19 vaccination in shipping and accompanying legal issues was published by the International Chamber of Shipping (www.ics-shipping.org).

Bernardino Ramazzini's De Morbis Artificum Diatriba on Workers' Health-the Birth of a New Discipline.

This paper provides a picture of the observations made over three hundred years ago by Bernardino Ramazzini (1633-1714) in light of current topical issues ranging from health problems related to work and lifestyle habits to the current burdensome COVID-19 pandemic. The main aspects of his work consist of descriptions of disorders linked to environmental risks, suggestions for measures for risk protection, and recommendations for healthy living. This paper focuses on Ramazzini's most relevant achievements by (1) analyzing the episodes that stimulated the composition of his main work and highlighting some observations on which current epidemiological and toxicological studies are based; (2) reviewing his work showing not only the systematic descriptions of work-related illnesses caused by occupational factors but also his sound etiological and physiopathological contributions to the field of occupational lung diseases, breast cancer, and environmental disorders; and (3) remarking on his main observations in the fields of risk prevention and health promotion, also in the light of some highly topical issues related to unhealthy lifestyle habits and the COVID-19 pandemic.

Practical Strategies and Tools for Use by Occupational and Environmental Medicine Departments During COVID-19 Pandemic Surges.

OBJECTIVES: Occupational and environmental medicine (OEM) departments in healthcare institutions can be quickly overwhelmed when COVID-19 infection rates rapidly and simultaneously increase in the workforce and the patients served. Our goal is to present a detailed toolkit of practical approaches for use by front-line OEM specialists to address workforce management tasks during pandemic surges. METHODS: Specific focus is on tasks related to employee symptom triage, exposure risk assessment, workplace contact tracing, and work restrictions. RESULTS: Tools include strategies used by customer call centers, two decision support algorithms (exposure due to cohabitation or non-cohabitation), a color-coded employee case tracking tool, a contact tracing protocol, and documentation templates that serve as memory aids for encounters. CONCLUSIONS: These tools are created with commonly used software. Implementation is feasible in most front-line OEM settings, including those with limited resources.

Personal Protective Equipment in COVID-19: Impacts on Health Performance, Work-Related Injuries, and Measures for Prevention.

OBJECTIVE: To assess impact of personal protective equipment (PPE) on healthcare providers (HCPs) in caring for COVID-19 patients. METHODS: A cross-sectional survey was conducted over 50 hospitals in China. Descriptive analyses and Chi-square tests were performed on the collected data. RESULTS: All 104 frontline HCPs report negative impacts of PPE on their clinical performance, 97% of them experienced discomfort and injuries caused by wearing PPE for long hours. Frontline HCPs provided suggestions to alleviate the negative impacts and to enhance communication between healthcare staff and patients. Two hundred eighty two non-frontline HCPs also revealed similar problems; however, we recorded a few discrepancies between answers given by frontline and non-frontline HCPs. CONCLUSIONS: Wearing PPE for long hours degrades health performance. Measures were suggested to improve the design of PPE for protecting HCPs and enhancing their services to COVID patients.

[Decisions on the state of health of employees and applicants for work with the use of ICT media]. / Wydawanie orzeczen o stanie zdrowia pracowników i osób ubiegajacych sie o prace z wykorzystaniem teleinformatycznych srodków przekazu.

BACKGROUND: The applicable law permits the use of information and communications technology (ICT) media in the process of providing health services, including preventive examinations. The right to perform preventive examinations using ICT should not be identified with an absolute obligation in this respect. An occupational medicine doctor may refuse to perform a preventive examination remotely if the specificity of medical activities and patient safety require personal contact with the doctor. The state of the epidemic prompted the legislator to adopt solutions enabling employees to continue working on the basis of an invalid decision, provided that it expired after March 7, 2020. The obligation to perform preventive examinations has been suspended, as a result of which their conduction during the epidemic is pointless. However, the obligations of the employee and the employer must be fulfilled in this respect immediately, but not later than within 60 days from the date of the epidemic cancellation. MATERIAL AND METHODS: The study uses the method of analyzing the currently applicable legal provisions allowing the use of ICT in the provision of health services. In addition, regulations governing the possibility of obliging employees to work remotely during the epidemic were also analyzed, together with the non-performance of preventive examinations and admissibility of work under a decision which had expired before March 7, 2020. RESULTS: Current legal regulations are ambiguous and cause interpretation difficulties. The possibility of issuing decisions as a result of preventive examinations is a potential risk of liability for doctors who do not have specialist knowledge in the field of occupational medicine. CONCLUSIONS: The solutions of the Act on COVID-19 regarding the performance of preventive examinations introduce new rights and obligations for employees and employers as well as doctors. Their implementation is necessary due to the purpose of the newly introduced regulations, whose task is to minimize the risk of the COVID-19 infection. At the same time, it is necessary to adopt a unified position with regard to the rights and obligations of doctors issuing decisions for the purposes specified in the Labor Code.
