Thermal discomfort in healthcare workers during the COVID-19 pandemic

Introduction:Due to the COVID-19 pandemic, healthcare workers are now required to use additional personal protective equipment (PPEs) to protect themselves against the virus. That led to an increased clothing insulation which is negatively affecting the perceived healthcare workers’ thermal sensation.Objectives:While demonstrating through software simulations the potential level of thermal discomfort healthcare workers involved in the COVID-19 emergency can be subjected to, this work aims at identifying measures to improve thermal sensation perception and acceptable thermal conditions for medical personnel.Methods:After having obtained the insulation values of individual clothing used by staff during COVID-19 emergency through the use of a thermal well-being evaluation software, the Fanger indexes (PMV - Predicted Mean Vote and PPD - Predicted Percentage of Dissatisfied) were calculated in order to estimate staff satisfaction to microclimatic conditions.Results:The use of COVID-19 additional PPEs with an air temperature equal to 22 °C (normally considered optimal) brings the PMV index equal to 0.6, which corresponds to 11.8 % being unsatisfied (PPD) due to perceived heat.Discussion:The use of additional protective devices significantly increases the clothing insulation level, facilitating the onset of conditions of thermal discomfort in the health workers. Workers engaged in the execution of nasopharyngeal swabs were most affected by the summer weather conditions and certainly represent the most critical category, for which it would be recommended to implement a higher turnover of service to reduce individual exposure time and consequent discomfort.     

Infection and death by COVID-19 in a cohort of healthcare workers in Mexico

Objective:This study aimed to estimate the risk of SARS-Cov2 infection and severe COVID-19 among healthcare workers from a major social security system.Methods:This study actively followed a cohort of social security workers from March to December 2020 to determine the number of laboratory-confirmed symptomatic cases, asymptomatic associated contacts and COVID-19-associated hospitalizations and deaths. Workers were classified into those providing direct care to infected patients (COVID teams), other active healthcare workers (OAHCW), and workers under home protection (HPW). The number of cases and rates were also estimated by job category.Results:Among a total of 542 381 workers, 41 461 were granted stay-at-home protection due to advanced age or comorbidities. Among the 500 920 total active workers, 85 477 and 283 884 were classified into COVID teams and OAHCW, respectively. Infection rates for COVID teams, OAHCW, and HPW were 20.1% [95% confidence interval (CI) 19.8–20.4], 13.7% (95% CI 13.5–13.8), and 12.2% (95% CI 11.8–12.5), respectively. The risk of hospitalization was higher among HPW. COVID teams had lower mortality rate per 10 000 workers compared to HPW (5.0, 95% CI 4.0–7.0 versus 18.1, 95% CI 14.0–23.0). Compared to administrative workers, ambulance personnel (RR 1.20; 95% CI 1.09–1.32), social workers (RR 1.16; 95% CI 1.08–1.24), patient transporters (RR 1.15; 95% CI 1.09–1.22) and nurses (RR 1.13; 95% CI 1.10–1.15) had a higher risk of infection after adjusting for age and gender. Crude differences in mortality rates were observed according to job category, which could be explained by differences in age, sex, and comorbidity distribution. Diabetes, obesity, hypertension, hemolytic anemia, and HIV were associated with increased fatality rates.Conclusions:COVID team workers had higher infection rates compared to the total population of active workers and HPW. Doctors had lower risk of infection than respiratory therapists, nurses, and patient transporters, among whom interventions should be reconsidered to reduce risks. The presence of comorbidities, such as diabetes, obesity, arterial hypertension, hemolytic anemia, and HIV, increased the likelihood of complications caused by COVID-19, culminating in a poor prognosis.     

Delay between COVID-19 complete vaccination and SARS-CoV-2 infection among healthcare workers

ObjectivesHealthcare workers (HCWs), at increased risk of coronavirus disease 2019 (COVID-19) were among the primary targets for vaccination, which became mandatory for them on September 15th, 2021 in France. In November they were confronted to the fifth COVID-19 wave despite excellent vaccine coverage. We aimed to estimate the incidence of SARS-CoV-2 infection after complete vaccination among HCWs with different vaccination schemes, and its determinants.MethodsWe enrolled all HCWs in the university hospital of Rennes, France who had received complete vaccination (two doses of COVID-19 vaccine). The delay from last vaccination dose to SARS-CoV-2 infection was computed. Fitted mixed Cox survival model with a random effect applied to exposure risk periods to account for epidemic variation was used to estimate the determinants of SARS-CoV-2 infection after complete vaccination.ResultsOf the 6674 (82%) HCWs who received complete vaccination (36% BNT162b2, 29% mRNA-1273, and 34% mixed with ChAdOx1 nCoV-19) and were prospectively followed-up for a median of 7.0 [6.3–8.0] months, 160 (2.4%) tested positive for SARS-CoV-2 by RT-PCR. Incidence density of SARS-CoV-2 infection after complete vaccination was 3.39 [2.89–3.96] infections per 1000 person-month. Median time from vaccine completion to SARS-CoV-2 infection was 5.5 [3.2–6.6] months. Using fitted mixed Cox regression with the delay as a time-dependent variable and random effect applied to exposure risk periods, age (P < 0.001) was independently associated with the incidence of SARS-CoV-2 infection. Vaccine schemes were not associated with SARS-CoV-2 infection (P = 0.068). A period effect was significantly associated with the incidence of SARS-CoV-2 infection (P < 0.001).ConclusionsIn this real-world study, incidence of SARS-CoV-2 infection increases with time in fully vaccinated HCWs with no differences according to the vaccination scheme. The short delay between complete vaccination and incident SARS-CoV-2 infection highlights the need for sustained barrier measures even in fully vaccinated HCWs.     

The role of resilience and coping among Italian healthcare workers during the COVID-19 pandemic

Objective:To evaluate the psychological state of healthcare workers (HCWs) in the field of rehabilitation during the COVID-19 pandemic.Methods:Cross-sectional observational study. Sample of 334 HCWs including: nurses, medical doctors, therapists, scientists, and clerical workers working at the IRCCS San Raffaele Roma rehabilitation hospital during the second wave of the COVID-19 pandemic. Anonymous web-based questionnaire included 14-item Resilience Scale, Brief-COPE, Hospital Anxiety Depression Scale, Fear of COVID-19 Scale. Occupational and sociodemographic characteristics.Results:High levels of resilience, low levels of anxiety, depression, and fear were observed in the study population; the most frequently used coping strategies in the Brief-COPE were acceptance, planning, and active coping. Specifically, 87% of the participants reported a moderate to high level of resilience, with the highest level observed in nurses while physicians show the lowest level. HCWs showed symptoms of anxiety (29%), depressive symptoms (10%), and fear caused by the COVID-19 pandemic (44%). Statistically significant differences were observed between different occupations for fear (p <0.05) and resilience (p <0.01). Levels of anxiety and fear appeared to be higher in female and younger workers. The latter group - who also reported higher levels of depression - showed lower levels of resilience.Conclusions:In our study hospital and non-hospital workers show different emotional, cognitive, and behavioural resources when facing stressful situations, like in the case of the SARS-CoV-2 pandemics. Our results support the role of resilience and the proper use of problem-focused and emotion-focused coping strategies as protective factors from psychological distress.     

Human parvovirus B19 infection in healthcare workers

This paper reports the occurrence of human parvovirus B19 infectionin seven healthcare workers in an acute hospital. The clinicalpresentation mimicked that of rubella and the diagnosis wasmade by the detection of human parvovirus B19 lgM antibody inblood samples taken from the affected members of staff. Thepaper discusses the importance of accurate diagnosis of B19infection because this virus has been implicated in causingor exacerbating a variety of medical conditions. B19 infectionmay be serious for people with chronic haemolytic anaemias,those who are immunocompromised or those who are pregnant. B19infection in pregnancy may be a cause of hydrops fetalis, particularlyif the infection occurs during the second trimester. This isin contrast to the risk of intra-uterine rubella infection whichis maximal in the first few weeks of pregnancy and which affectsfetal development. The paper highlights the need for guidelinesfor occupational health practitioners on the management of parvovirusB19 infection and the need to make healthcare workers awareof the importance of this infection.     

Mental health status of healthcare workers at a third line tunisian hospital during COVID-19 pandemic

Introduction: During the COVID-19(coronavirus-19 disease) pandemic, health care workers (HCWs) faced the risk of infection and distressing work to meet health requirements. The aim of the present stud ywas to evaluate perceptions of HCWs of their security at work in COVID-19 units and their coping strategies, at the military hospital of Tunis, during the second wave of COVID-19. Methods:A cross-sectional study was conducted via an auto-questionnaire on February 2021.HCWs of the military hospital of Tunis were included. Participants were asked about their perceived security at work in COVID-19 units and their coping behaviors. Mental disorders were assessed, via qualitative questionnaires. Results:A total of 110 HCWs’ responses were collected. Fifty-eight participants (52.7%) were females. The mean age was 33.7 years (SD 9.3). They were doctors at 45.5% and nurses at 39.1%. HCWs declared having worked in COVID-19 units in 81.8% of cases. The participants reported their fears about being infected in 58.2% and infecting family members in 85.5% of cases. Protective factors included information about the disease (80%), availability of personal protective equipment (PPE) (80.9%), support from colleagues(72.7%)or superiors at work (50.9%), and ability to communicate with others (63.6%). Depression, anxiety, and insomnia were found in respectively 25.5%, 30%, and 41.8% of HCWs. In multivariate analysis, suffering from a traumatic distress was significantly associated with anxiety and depression (p<0.01 and, p<0.05 respectively). In addition, insomnia severity was linked to age (p=0.05) and having colleagues infected with COVID-19 (p<0.05). Conclusion:In the present study, HCWs of the military hospital of Tunis stated having high levels of insomnia, anxiety, and depression since the early outbreak of the COVID-19 pandemic. These mental disorders may have a negative impact on the quality of life of HCWs and should be enhanced by psychological support and preventive measures.

The deterioration of mental health among healthcare workers during the COVID-19 outbreak: A population-based cohort study of workers in Japan

Objectives:This study compared the longitudinal change in the mental health of healthcare and non-healthcare workers during two months of the COVID-19 outbreak in Japan.Methods:Data were derived from a prospective online cohort study of 1448 full-time employees in Japan. Participants were surveyed at baseline from 19–22 March 2020 (T1) and at follow-up from 22–26 May 2020 (T2). A self-administered online questionnaire was used to assess participants’ fear and worry of COVID-19, psychological distress, and physical symptoms at T1 and T2. A series of generalized linear models were created to assess changes in outcomes between healthcare and non-healthcare workers. Demographic variables (ie, sex, age, marital status, child[ren], education, and residential area) were included in the models as covariates.Results:A total of 1032 participants completed the follow-up questionnaire at T2 (follow-up rate, 72.6%). After excluding unemployed respondents (N=17), the final sample comprised 1015 full-time employees (111 healthcare and 904 non-healthcare workers). After adjusting for the covariates, psychological distress (and subscales of fatigue, anxiety, and depression) as well as fear and worry of COVID-19 increased statistically significantly more among healthcare than non-healthcare workers from T1 to T2.Conclusions:Psychological distress, together with fear and worry of COVID-19, increased more among healthcare compared to non-healthcare workers during the COVID-19 outbreak. The study confirmed that healthcare workers are an important target for mental healthcare during the COVID-19 outbreak.     

COVID-19 impact and vaccine effectiveness among healthcare workers of a large University Hospital in Lombardy,Italy

Background:Healthcare Workers (HCWs) are a key element in managing the COVID-19 pandemic, but they are also at high risk of infection.Objective:The aim of this study was to describe, in a large university hospital which provided healthcare services to patients with SARS-CoV-2 infection, the course of the epidemic among HCWs and effectiveness of COVID-19 vaccination in reducing SARS-CoV-2 infection and disease.Methods:Our case series included all “Fatebenefratelli Sacco” University Hospital workers. Data were collected until the 15th of May 2021 and analysed as part of the health surveillance program carried out by the Occupational Health Unit.Results:From March 2020 until May 2021, 14.4% of workers contracted COVID-19, with the highest incidence peak recorded during the second wave of the pandemic. The prevalence of infection was slightly higher in males than in females, and a greater number of cases was found in job categories characterized by direct patient care activities. We reported a higher prevalence of “serious/critical illness” in elder workers. A clear reduction of COVID-19 incidence was found in our population during the third pandemic wave, that coincided with the start of vaccination campaign.Discussion:HCWs have been at high risk of COVID-19 infection. Male sex and advanced age appear to be predisposing factor and negative prognostic factor respectively. An out-of-hospital setting appears to be the main source of COVID-19 confirming that the correct use of protective devices during work counters the risk of infection. Vaccination seems to reduce both documented cases of infection and severe illness.     

Entanglements of affect,space, and evidence in pandemic healthcare: An analysis of Australian healthcare workers’ experiences of COVID-19

The COVID-19 pandemic continues to highlight both global interconnectedness and schisms across place, context and peoples. While countries such as Australia have securitised their borders in response to the global spread of disease, flows of information and collective affect continue to permeate these boundaries. Drawing on interviews with Australian healthcare workers, we examine how their experiences of the pandemic are shaped by affect and evidence ‘traveling’ across time and space. Our analysis points to the limitations of global health crisis responses that focus solely on material risk and spatial separation. Institutional responses must, we suggest, also consider the affective and discursive dimensions of health-related risk environments.     

COVID-19 vaccine uptake and its associated factors among Palestinian healthcare workers: Expectations beaten by reality

BackgroundIn response to this extraordinary outbreak, many countries and companies rush to develop an effective vaccine, authorize, and deliver it to all people across the world. Despite these extensive efforts, curbing this pandemic relies highly upon vaccination coverage. This study aimed to determine SARS-COV-2 vaccine uptake among Palestinian healthcare workers, the factors that influence vaccination uptake, and the motivators and barriers to vaccination.MethodsA cross-sectional study was conducted using an online anonymous self-administered questionnaire during April and May 2021, after the Palestinian Ministry of Health launched the COVID-19 vaccination campaign.The questionnaire collected socio-demographic characteristics, vaccination attitude and vaccination uptake status, and motivators and barriers towards vaccination. In addition, multivariate logistic regression was performed to identify the influencing factors of vaccination uptake.ResultsThe study included 1018 participants from different professions, including 560 (55.0%) females. Of the participants, 677 (66.5%; 95% CI: 63.5–69.4%) received the vaccine. Higher uptake was observed among males (aOR = 1.5; 95 %CI: 1.1–2.1), single HCWs (aOR = 1.3; 95 %CI: 1.1–1.8), HCWs working in the non-governmental sector (aOR = 1.6; 95 %CI: 1.2–2.4), higher monthly income (aOR = 1.9; 95 %CI: 1.4–2.8) and smoking (aOR = 1.5; 95 %CI: 1.1–3.5). The lower level of negative vaccination attitudes predicted higher intake; mistrust of vaccine belief (aOR = 1.6; 95 %CI: 1.4–1.7) and worries over unforeseen future effects (aOR = 1.2; 95 %CI: 1.1–1.3).ConclusionIn conclusion, the COVID-19 vaccination uptake was comparable to other studies worldwide but still needs to be improved, especially in the context of this ongoing global pandemic. It is imperative to invest resources to promote vaccination uptake and target all the vaccine misconceptions and fears.     

The impact of personal coaching on influenza vaccination among healthcare workers before and during COVID-19 pandemic

BackgroundWithout the implementation of mandatory vaccination, it was difficult to increase the influenza vaccination rate among healthcare workers. We described the strategy of personal coaching and assess its impact in increasing the influenza vaccination rate among healthcare workers in Hong Kong.MethodsPersonal coaching of individual staff led by the infection control officer (ICO) and senior nursing officer (SNO) from infection control team could overcome barriers and promote on-site vaccination. The influenza vaccination rates among different categories of staff in 2016/2017 (year 1, baseline), 2017/2018 (year 2, promotion using social media), and 2018/2019 to 2020/2021 (year 3–5, promotion using personal coaching) were analysed in a healthcare region with 8490 ± 206 staff during the study period.ResultsWith the implementation of personal coaching, the influenza vaccination rates increased significantly among medical (65.0% vs 57.0%, p = 0.048), nursing (30.6% vs 21.1%, p < 0.001), allied health (37.0% vs 27.4%, p < 0.001), care-related supporting staff (37.7% vs 27.3%, p < 0.001), and non-professional staff (27.3% vs 22.3%, p < 0.001) in year 3 compared with year 2, and also significantly increased among all staff in year 4 (38.0% vs 34.7%, p < 0.001) and year 5 (45.2% vs 38.0%, p < 0.001) when compared with the preceding year. The increase in vaccination rate was not apparent with social media promotion alone (26.4%, year 2 vs 25.6%, year 1, p = 0.305).ConclusionPersonal coaching led by ICO and SNO significantly increased the vaccination rates among healthcare workers in 3 consecutive years. This model could be promulgated to unit heads to establish a hospital culture conducive to vaccination.     

Characteristics of Work-related COVID-19 in Croatian Healthcare Workers: A Preliminary Report

Healthcare workers (HCWs) are considered to run a higher occupational risk of becoming infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and develop coronavirus disease (COVID-19) than the rest of the population. The aim of this study was to describe and analyse the characteristics of work-related COVID-19 in Croatian HCWs. Study participants were HCWs who contacted their occupational physician between 1 May 2020 and 12 November 2020 with a request for the registration of COVID-19 as an occupational disease. All participants filled out our online Occupational COVID-19 in Healthcare Workers Questionnaire. The study included 59 HCWs (median age 45.0, interquartile range 36.0–56.0 years). Most (78 %) were nurses or laboratory technicians, and almost all (94.9 %) worked in hospitals. Hierarchical cluster analysis revealed three clusters of COVID-19-related symptoms: 1) elevated body temperature with general weakness and fatigue, 2) diarrhoea, and 3) headache, muscle and joint pain, anosmia, ageusia, and respiratory symptoms (nasal symptoms, burning throat, cough, dyspnoea, tachypnoea). Almost half (44.6 %) reported comorbidities. Only those with chronic pulmonary conditions were more often hospitalised than those without respiratory disorders (57.1 % vs. 2.5 %, respectively; P=0.001). Our findings suggest that work-related COVID-19 among Croatian HCWs is most common in hospital nurses/laboratory technicians and takes a mild form, with symptoms clustering around three clinical phenotypes: general symptoms of acute infection, specific symptoms including neurological (anosmia, ageusia) and respiratory symptoms, and diarrhoea as a separate symptom. They also support evidence from other studies that persons with chronic pulmonary conditions are at higher risk for developing severe forms of COVID-19.Key words: comorbidity, hospitalisation, questionnaire, SARS-CoV-2, symptom clustering     

The impact of COVID-19 pandemic on temporal trends of workplace violence against healthcare workers in the emergency department

BackgroundIt is known that there has been an increase over the years in attacks by patients admitted to the emergency department (ED) on healthcare workers; it is unclear what effect the COVID-19 pandemic has on these attacks.Aimto verify through a long-term time analysis the effect of COVID-19 on ED attacks on healthcare workers.Mothodsa quasi-experimental interrupted time-series analysis on attacks on healthcare workers was performed from January 2017 to August 2021. The main outcome was the monthly rate of attacks on healthcare workers per 1000 general accesses. The pandemic outbreak was used as an intervention point.Results1002 attacks on healthcare workers in the ED were recorded. The rate of monthly attacks on total accesses increased from an average of 13.5 (SD 6.6) in the pre-COVID-19 era to 27.2 (SD 9.8) in the pandemic months, p < 0.001. The pandemic outbreak led to a significant increase in attacks on healthcare workers from 0.05/1000 attacks per month (p = 0.018), to 4.3/1000 attacks per month (p = 0.005).ConclusionsThe COVID-19 pandemic has led to a significant increase in attacks on healthcare workers in the ED. Trends compared to pre-pandemic months do not seem to indicate a return to normality. Health institutions and policymakers should develop strategies to improve the safety of the working environment in hospitals and EDs.     

Healthcare worker perspectives on COVID-19 vaccines: Implications for increasing vaccine acceptance among healthcare workers and patients

ObjectiveTo understand COVID-19 vaccine perspectives among healthcare workers serving diverse communities.MethodsA dual English/Spanish survey was distributed to healthcare workers in the United States from 3/12/2021–4/22/2021 by the Migrant Clinicians Network, Society of Refugee Healthcare Providers, a Federally Qualified Healthcare Center, and social media advertisement to general primary care workers.Results517 responses were at least 50% complete and included in the analysis. Among these, 88% (457/517) indicated vaccine acceptance. Factors associated with acceptance included not reporting any vaccine concerns, identifying as male, ≥65 years of age, being a physician or advanced practice provider, and interacting directly with patients from refugee, immigrant, and migrant (RIM) communities. Participants identified educational information as most helpful for themselves when making a vaccine decision, but a healthcare provider’s recommendation as most helpful for their patients.ConclusionHealthcare workers, especially those serving RIM communities, are vaccine accepting. Tailoring vaccine-related information to healthcare workers may improve vaccine confidence for both themselves and patients who rely on them for information.
