Introduction Healthcare workers (HCWs), particularly those from ethnic minority groups, have been shown to be at disproportionately higher risk of infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) compared to the general population. However, there is insufficient evidence on how demographic and occupational factors influence infection risk among ethnic minority HCWs. Methods We analysed data from the United Kingdom Research study into Ethnicity And COVID-19 Outcomes in Healthcare workers (UK-REACH) cohort study. We used logistic regression to examine associations of demographic, household and occupational predictor variables with SARS-CoV-2 infection (defined by PCR, serology or suspected COVID-19) in a diverse group of HCWs. Results 2,496 of the 10,772 HCWs (23.2%) who worked during the first UK national lockdown in March 2020 reported previous SARS-CoV-2 infection. In an adjusted model, demographic and household factors associated with increased odds of infection included younger age, living with other key workers and higher religiosity. Important occupational risk factors associated with increased odds of infection included attending to a higher number of COVID-19 positive patients (aOR 2.49, 95%CI 2.03—3.05 for ≥21 patients per week vs none), working in a nursing or midwifery role (1.35, 1.15—1.58, compared to doctors), reporting a lack of access to personal protective equipment (1.27, 1.15 — 1.41) and working in an ambulance (1.95, 1.52—2.50) or hospital inpatient setting (1.54, 1.37 — 1.74). Those who worked in Intensive Care Units were less likely to have been infected (0.76, 0.63—0.90) than those who did not. Black HCWs were more likely to have been infected than their White colleagues, an effect which attenuated after adjustment for other known predictors. Conclusions We identified key sociodemographic and occupational risk factors associated with SARS-CoV-2 infection amongst UK HCWs, and have determined factors that might contribute to a disproportionate odds of infection in HCWs from Black ethnic groups. These findings demonstrate the importance of social and occupational factors in driving ethnic disparities in COVID-19 outcomes, and should inform policies, including targeted vaccination strategies and risk assessments aimed at protecting HCWs in future waves of the COVID-19 pandemic.

Introduction: Coronavirus disease 2019 (COVID-19) has spread rapidly worldwide, causing a global public health crisis. Healthcare workers (HCWs) are vulnerable due to their role in the management of COVID-19 infected patients. As of June 2020, a total of 847 HCWs in Oman had reportedly contracted COVID-19, with an incidence rate of 1.47%. This study therefore aimed to identify factors associated with COVID-19 infection among HCWs in Muscat Governorate, Oman, as well as to evaluate adherence to infection prevention and control (IPC) measures. Methods: This cross-sectional study involved cases of laboratory-confirmed COVID-19 infection among HCWs working under the Directorate General of Health Services of Muscat Governorate, Ministry of Health, between February and June 2020. Data regarding the participants’ sociodemographic characteristics, risk factors, pre-existing medical conditions, and adherence to IPC measures were collected using a self-administered questionnaire distributed via a web-based mobile application. Results: A total of 126 HCWs with confirmed COVID-19 infection participated in the study. Of these, 72.2% were female, 53.2% worked in primary care facilities, and 61.1% were medical doctors or nurses. Only 18.1% were over 45 years of age and 30.2% had pre-existing medical conditions. While 29.4% had never received IPC training, the majority followed recommended hand hygiene practice (96.8%) and social distancing protocols (93.7%) and wore protective facemasks for routine patient care (96.9%). Conclusion: While the majority of HCWs followed crucial IPC measures, one-third had never received specific IPC training or faced restrictions on PPE use. HCWs, including those in housekeeping and administrative functions are recommended to undergo rigorous IPC training. In addition, high-risk HCWs could be assigned duties away from active COVID 19 cases. It is recommended to restructure health facilities for better adherence to IPC standards.

Insomnia Symptoms

Background: Healthcare workers (HCWs) have been exposed to increased risks of insomnia and fatigue during the COVID-19 pandemic. In this study, we identify important risk factors associated with insomnia symptoms and fatigue among HCWs, and evaluate the effect of organizational support on insomnia and fatigue symptoms.Methods: This is an online cross-sectional survey of HCWs in China administered during the COVID-19 epidemic (from February 27, 2020 to March 12, 2020). We employed the AIS-8 scale for insomnia screening, and a self-reported ten-point scale to evaluate subjects' degrees of fatigue. We also designed a four-point scale to assess the degree of social support provided on an organizational level. Additionally, we conducted logistic regression analysis to identify risk factors.Results: This study included a total of 3,557 participants, 41% of which consisted of non-frontline HCWs and 59% of which was frontline HCWs. Of the non-frontline HCWs, 49% reported insomnia symptoms, and 53.8% reported a moderate to high degree of fatigue. Meanwhile, among the frontline HCWs, the percentages for insomnia and moderate to high fatigue were 63.4% and 72.2%, respectively. Additionally, frontline HCWs and HCWs employed at Centers for Disease Control and Prevention (CDCs) had elevated risks of insomnia and fatigue. However, with increased organizational support, insomnia symptoms decreased among frontline HCWs. Also, organizational support mitigated the positive correlation between daily working hours and degree of fatigue among HCWs.Conclusion: Frontline HCWs and staff in Chinese CDCs have been at a high risk of insomnia symptoms and fatigue during the fight against COVID-19. This study provides evidence for the positive effects of organizational support in relation to insomnia and fatigue among HCWs. This sheds light on government responses to the COVID-19 epidemic for other countries.

Abstract Objective: To better understand COVID-19 transmission among healthcare workers (HCW), we investigated occupational and non-occupational risk factors associated with cumulative COVID-19 incidence among a Massachusetts HCW cohort. Design, setting, and participants: The retrospective cohort study included adult HCWs in a single healthcare system from March 9 to June 3, 2020. Methods: Participants’ SARS-CoV-2 nasopharyngeal RT-PCR results and demographics were de-identified and extracted from an established occupational health, COVID-19 database at the healthcare system. HCWs from each particular job grouping had been categorized into frontline/non-frontline workers. Incidence rate ratio (IRR) and odds ratio were used to compare subgroups after excluding HCWs involved in early infection clusters before universal masking. A sensitivity analysis was performed comparing jobs with the greatest potential occupational risks with others. Results: 152 out of 5177 (2.94%) HCWs were diagnosed with COVID-19. Affected HCWs resided in areas with higher community attack rates (median: 1755.2 vs. 1412.4 cases per 100,000, P<0.001)(multivariate-adjusted IRR: 1.89, 95%CI: 1.03–3.44 comparing 5th to 1st quintile of community rates). After multivariate adjustment, African Americans and Hispanics had higher incidence than non-Hispanic white HCWs (IRR: 2.78, 95%CI: 1.78–4.33; and IRR: 2.41, 95%CI: 1.42–4.07, respectively). After adjusting for race and residential rates, frontline HCWs had a higher IRR (1.73, 95%CI: 1.16–2.54) compared to non-frontline HCWs overall, but not within specific job categories, nor when comparing the highest risk jobs to others. Conclusions: After universal masking was instituted, the strongest risk factors associated with HCWs’ COVID-19 infection were residential community infection rate and race.

Background: Work-related asthma phenotypes in health workers (HWs) exposed to cleaning agents have not been investigated extensively as other occupational exposures. This study aimed to describe asthma phenotypes and to identify important host risk factors associated with various asthma-related outcomes.Methods: A cross-sectional study of 699 HWs was conducted in two large tertiary hospitals. A total of 697 HWs completed questionnaire interviews. Sera collected from 682 HWs were analyzed for atopy (Phadiatop) and IgE to occupational allergens (NRL—Hev b5, Hev b6.02; chlorhexidine and ortho-phthalaldehyde—OPA). Methacholine (MCT), bronchodilator challenge (BDR) and fractional exhaled nitric oxide (FeNO) were performed. An asthma symptom score (ASS) used five asthma-related symptoms reported in the past 12 months. Current asthma was based on use of asthma medication or an asthma attack or being woken up by an attack of shortness of breath in the past 12 months. Nonspecific bronchial hyperresponsiveness (NSBH) was defined as having either a positive MCT or a significant bronchodilator response. Two continuous indices of NSBH [continuous index of responsiveness (CIR) and dose-response slope (DRS)] were calculated.Results: The prevalence of current asthma was 10%, atopic asthma (6%) and non-atopic asthma (4%). Overall, 2% of subjects had work-related asthma. There was a weak positive association between NSBH and FeNO [CIR: Beta coefficient (β) = 0.12; CI: 0.03–0.22 and DRS: β = 0.07; CI: 0.03–0.12]. Combining FeNO ≥ 50 ppb with a BDR [mean ratio (MR) = 5.89; CI: 1.02–34.14] or with NSBH (MR = 4.62; CI: 1.16–18.46) correlated better with ASS than FeNO alone (MR = 2.23; CI: 1.30–3.85). HWs with current asthma were twice as likely to be atopic. FeNO was positively associated with atopy (OR = 3.19; CI: 1.59–6.39) but negatively associated with smoking status (GMR = 0.76; CI: 0.62–0.94). Most HWs sensitized to occupational allergens were atopic.Conclusion: Atopic asthma was more prevalent than non-atopic asthma in HWs. Most asthma-related outcomes were positively associated with allergic predictors suggesting a dominant role for IgE mechanisms for work-related symptoms and asthma associated with sensitization to OPA or chlorhexidine.
