Physician homicide: Reports in the National Violent Death Reporting System (2003-2018).

OBJECTIVE: To explore the occurrence, demographics, and circumstances of homicides of physicians. METHOD: Authors interrogated the National Violent Death Reporting System (NVDRS), the Centers for Disease Control and Prevention's surveillance system tracking violent deaths between 2003 and 2018 which integrates data from law enforcement and coroner/medical examiner reports. Authors identified cases of homicide decedents whose profession was physician, surgeon, or psychiatrist. Data collected included decedents' demographics as well as circumstances of death. RESULTS: Data were provided by 7-41 states as participating states increased over time. Fifty-six homicides were reported, most were male (73.2%) and white (76.8%). Most (67.9%) identified assailants reportedly knew decedents: 23.2% were perpetrated by partners/ex-partners; 10.7% by patients/patients' family members. Deaths were mainly due to gunshot wounds (44.6%), stabbing (16.1%), and blunt force trauma (16.1%). More (58.9%) homicides occurred at victims' homes than work (16.1%). CONCLUSIONS: Physician homicides are relatively rare and occur at lower rates than in the general population. Physicians were more frequently killed by partners or ex-partners than by patients. Most homicides occurred away from the workplace. Broader efforts are needed to promote interventions throughout America's violent society to reduce domestic/partner violence and gun violence.

Prevalence, risk factors and psychological consequences of workplace violence among health workers in the Greater Accra region, Ghana: a cross-sectional study.

BACKGROUND: Globally, close to one-third of all workplace violence (WV) occurs in the health sector. Exposure to WV among healthcare professionals in Ghana has been widely speculated, but there is limited evidence on the problem. This study therefore investigated WV, its risk factors, and the psychological consequences experienced by health workers in Ghana. METHODS: An analytic cross-sectional study was conducted in the Greater Accra region from January 30 to May 31, 2023, involving selected health facilities. The participants for the study were selected using a simple random sampling technique based on probability proportional-to-size. The data analyses were performed using STATA 15 software. Logistic regression analyses were employed to identify the factors associated with WV, considering a significance level of p-value < 0.05. RESULTS: The study was conducted among 607 healthcare providers and support personnel across 10 public and private hospitals. The lifetime career, and one-year exposure to any form of WV was 414 (68.2%) [95% CI: (64.3-71.9%)] and 363 (59.8%) [95% CI: (55.8-63.7%)], respectively. Compared to other forms of WV, the majority of healthcare workers, 324 (53.4%) experienced verbal abuse within the past year, and a greater proportion, 85 (26.2%) became 'super alert' or vigilant and watchful following incidents of verbal abuse. Factors significantly linked to experiencing any form of WV in the previous 12 months were identified as follows: older age [AOR = 1.11 (1.06, 1.17)], working experience [AOR = 0.91 (0.86, 0.96)], having on-call responsibilities [AOR = 1.75 (1.17, 2.61)], and feeling adequately secure within health facility [AOR = 0.45 (0.26, 0.76)]. CONCLUSION: There was high occurrence of WV, and verbal abuse was the most experienced form of WV. Age, work experience, on-call duties, and security within workplace were associated with exposure to WV. Facility-based interventions are urgently needed to curb the incidence of WV, especially verbal abuse.

Associations between patient safety culture and workplace safety culture in hospital settings.

BACKGROUND: Strong cultures of workplace safety and patient safety are both critical for advancing safety in healthcare and eliminating harm to both the healthcare workforce and patients. However, there is currently minimal published empirical evidence about the relationship between the perceptions of providers and staff on workplace safety culture and patient safety culture. METHODS: This study examined cross-sectional relationships between the core Surveys on Patient Safety Culture™ (SOPS®) Hospital Survey 2.0 patient safety culture measures and supplemental workplace safety culture measures. We used data from a pilot test in 2021 of the Workplace Safety Supplemental Item Set, which consisted of 6,684 respondents from 28 hospitals in 16 states. We performed multiple regressions to examine the relationships between the 11 patient safety culture measures and the 10 workplace safety culture measures. RESULTS: Sixty-nine (69) of 110 associations were statistically significant (mean standardized ß = 0.5; 0.58 < standardized ß < 0.95). The largest number of associations for the workplace safety culture measures with the patient safety culture measures were: (1) overall support from hospital leaders to ensure workplace safety; (2) being able to report workplace safety problems without negative consequences; and, (3) overall rating on workplace safety. The two associations with the strongest magnitude were between the overall rating on workplace safety and hospital management support for patient safety (standardized ß = 0.95) and hospital management support for workplace safety and hospital management support for patient safety (standardized ß = 0.93). CONCLUSIONS: Study results provide evidence that workplace safety culture and patient safety culture are fundamentally linked and both are vital to a strong and healthy culture of safety.

Evaluation of the characteristics of injured workers and employer compliance with OSHA's reporting requirement for work-related amputations.

INTRODUCTION: In 2014, the Federal Occupational Safety and Health Administration (OSHA) enacted a standard requiring employers to report work-related amputations to OSHA within 24 hours. We studied the characteristics of the injured workers and employer compliance with the regulation in Michigan. METHODS: Two independent data sets were used to compare work-related amputations from 2016 to 2018: employer reports to OSHA and the Michigan Multi-Source Injury and Illness Surveillance System (MMSIISS). We deterministically linked employer reports to OSHA with the MMSIISS by employee name, employer name, date, and type of amputation. RESULTS: We identified 1366 work-related amputations from 2016 to 2018; 575 were reported by employers to OSHA and 1153 were reported by hospitals to the MMSIISS. An overlap of 362 workers were reported in both systems, while 213 workers were only reported by employers to OSHA and 791 workers were only reported by hospitals. Employer compliance with the regulation was 42.1%. Employer compliance with reporting was significantly less in: agriculture, forestry, fishing, and hunting (14.6%); construction (27.4%); retail trade (20.7%); arts, entertainment, and recreation (7.7%); accommodation and food services (13.0%); and other services (27.0%). Large employers and unionized employers were significantly more likely (67.9% and 92.7%, respectively) and small employers were significantly less likely (18.2%) to comply with the reporting rule. Enforcement inspections at 327 workplaces resulted in 403 violations; of those, 179 (54.7%) employers had not corrected the amputation hazard before the time of inspection. DISCUSSION: Michigan employers reported less than half of the work-related amputations required by OSHA's reporting regulation. Noncompliance was greatest in small employers, and agriculture, forestry, fishing, and hunting; construction; arts, entertainment, and recreation; accommodation and food services; and retail and other service industries. Inspections found that over half of the employers had not corrected the hazard that caused the amputation at the time of the inspection's initial opening date; in these cases, abatement of any hazards identified would have occurred after the inspection. Improved compliance in employer reporting of work-related amputations will identify hazards posing a high risk of recurrence of injury to other workers from the same injury source. Greater compliance can also help target safety-related preventive and intervention efforts in industries that might otherwise be overlooked.

Spillover effects of organizational support for patient and workplace safety on safety outcomes: The mediating role of safety compliance.

AIM(S): To investigate spillover effects of organizational support for patient and workplace safety on safety outcomes and to examine the mediating role of safety compliance in these relationships. DESIGN: A cross-sectional, correlational survey design. METHODS: This study analysed data from 1255 nurses in 34 Korean hospitals. A structured questionnaire was used including items from the Hospital Survey on Patient Safety Culture and Safety Compliance scales. Data were collected between February and June 2022. We employed structural equation modelling (SEM) for analysis with a significance level set at 0.05. RESULTS: Organizational support for patient and workplace safety showed direct impacts on patient and workplace safety outcomes. Findings supported our hypotheses regarding spillover effects, as organizational support for patient safety was related to enhanced workplace safety and organizational support for workplace safety was associated with improved patient safety. SEM analysis showed safety compliance's mediating role. When the distribution of serial indirect effects was examined, three out of eight indirect pathways were statistically significant. CONCLUSION: Improving organizational support for patient safety can lead to better workplace safety outcome, and enhancing support for workplace safety can result in better patient safety outcome. Given this mutually beneficial relationship, healthcare organizations should simultaneously promote safety in both areas rather than focusing on just one. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Study results highlight the need to recognize the interconnected nature of patient and workplace safety in order to achieve better overall safety outcomes. IMPACT: This study shows that organizational safety efforts for patients and workers are interconnected and mutually beneficial. The study's results have both theoretical and practical implications in demonstrating that organizational support for both patient and workplace safety plays a strong role in promoting nurses' safety compliance and improving overall safety outcomes. REPORTING METHOD: STROBE checklist. PATIENT CONTRIBUTION: No patient or public contribution.

Occupational safety in homecare organizations: the design and implementation of a train-the-trainer program.

Homecare workers face significant occupational risks, necessitating effective safety training programs. This paper presents a comprehensive Train-the-Trainer (TTT) program developed to enhance occupational safety in homecare organizations. Through an analysis of 229 reported safety events, the frequency and type of incidents, such as injuries during handling, road crashes, slips, trips, and falls, were identified and primarily attributed to human errors and violations. Based on the results, a TTT program was designed and implemented. The TTT successfully engaged Health, Safety, and Environment managers, fostering collaborative activities, knowledge sharing, and resource discussions. The program modules address critical areas, including distractions and inattentions, fatigue, time pressure, frustration and aggressiveness, and safety behaviors. This innovative approach provides valuable insights for organizations seeking to improve homecare workers' safety. The findings add to the broader comprehension of occupational safety in the homecare sector, proposing a pragmatic framework for future interventions.

Factors Affecting Workers' Mental Stress in Handover Activities During Human-Robot Collaboration.

OBJECTIVE: This study investigated the effects of different approach directions, movement speeds, and trajectories of a co-robot's end-effector on workers' mental stress during handover tasks. BACKGROUND: Human-robot collaboration (HRC) is gaining attention in industry and academia. Understanding robot-related factors causing mental stress is crucial for designing collaborative tasks that minimize workers' stress. METHODS: Mental stress in HRC tasks was measured subjectively through self-reports and objectively through galvanic skin response (GSR) and electromyography (EMG). Robot-related factors including approach direction, movement speed, and trajectory were analyzed. RESULTS: Movement speed and approach direction had significant effects on subjective ratings, EMG, and GSR. High-speed and approaching from one side consistently resulted in higher fear, lower comfort, and predictability, as well as increased EMG and GSR signals, indicating higher mental stress. Movement trajectory affected GSR, with the sudden stop condition eliciting a stronger response compared to the constrained trajectory. Interaction effects between speed and approach direction were observed for "surprise" and "predictability" subjective ratings. At high speed, approach direction did not significantly differ, but at low speeds, approaching from the side was found to be more surprising and unpredictable compared to approaching from the front. CONCLUSION: The mental stress of workers during HRC is lower when the robot's end effector (1) approaches a worker within the worker's field of view, (2) approaches at a lower speed, or (3) follows a constrained trajectory. APPLICATION: The outcome of this study can serve as a guide to design HRC tasks with a low level of workers' mental stress.

A few thoughts on workplace safety.

In an industry known for its workplace hazards, such as the management and manipulation of animals that could bite, kick or cause considerable damage simply because of their size, combined with long working hours, lifting of heavy loads and the general mental stress, it is perhaps surprising that the veterinary industry is not also known for its safety culture and structures. One would expect that where such hazards and risks have been identified, there would be many and varied levels of education on risk and hazard management, a comprehensive set of tools with which to mitigate these risks as well as discussion and debriefing of significant adverse events to ensure they do not occur again. One would also assume that there would be a strong sense of safety culture in the workplace and that personnel would expect each other to ensure that the health and safety of themselves and their colleagues was a number one priority. Yet, is this the case in the veterinary industry? A request was made by the Association of Veterinary Anaesthetists (AVA) to provide 'safety guidelines' for use in general practice, particularly pertaining to pregnancy. The AVA set up a task force to address these concerns and to determine if guidelines could be created. This article is offered as a starting point for considering safety in the veterinary industry in a broad sense, with the hope that in the future there may be development of such guidelines. It is hoped that this article also provides the stimulus for further research in this area.

Adopting a "Digital First" Mindset for Workplace Safety and Health in Singapore.

Digital and technological solutions constitute a key enabler to achieving better workplace safety and health outcomes. Fundamentally, the success of their implementation is underscored by a need for employers, employees, industry stakeholders and policymakers to collaborate in adopting a "digital first" mindset. This review provides a background on the evolution of work and the workforce in post-independence Singapore, and introduces pertinent local workplace safety and health trends. It delves into how a "digital first" approach may be adopted and effected, followed by challenges and opportunities in the digitalization of Singapore's workplace safety and health landscape. Illustrative examples are used to highlight applications of digital and technological solutions in the control of occupational hazards. In our discussion, workplace strategies are built around the hierarchy of controls framework, whereas worker-related strategies are divided into workspace optimization for productivity/performance enhancement, training/education, and instituting surveillance/open reporting mechanisms. We demonstrate that with an open and forward-looking mind, and well-executed change management, we will be able to capitalize on technological advances to improve work and working conditions for all workers.

Characterizing worker compensation claims in long-term care and examining the association between facility characteristics and severe injury: a repeated cross-sectional study from Alberta, Canada.

BACKGROUND: Despite the physical demands and risks inherent to working in long-term care (LTC), little is known about workplace injuries and worker compensation claims in this setting. The purpose of this study was to characterize workplace injuries in LTC and to estimate the association between worker and organizational factors on severe injury. METHODS: We used a repeated cross-sectional design to examine worker compensation claims between September 1, 2014 and September 30, 2018 from 25 LTC homes. Worker compensation claim data came from The Workers Compensation Board of Alberta. LTC facility data came from the Translating Research in Elder Care program. We used descriptive statistics to characterize the sample and multivariable logistic regression to estimate the association between staff, organizational, and resident characteristics and severe injury, measured as 31+ days of disability. RESULTS: We examined 3337 compensation claims from 25 LTC facilities. Less than 10% of claims (5.1%, n = 170) resulted in severe injury and most claims did not result in any days of disability (70.9%, n = 2367). Most of the sample were women and over 40 years of age. Care aides were the largest occupational group (62.1%, n = 2072). The highest proportion of claims were made from staff working in voluntary not for profit facilities (41.9%, n = 1398) followed by public not for profit (32.9%, n = 1098), and private for profit (n = 25.2%, n = 841). Most claims identified the nature of injury as traumatic injuries to muscles, tendons, ligaments, or joints. In the multivariable logistic regression, higher staff age (50-59, aOR: 2.26, 95% CI 1.06-4.83; 60+, aOR: 2.70, 95% CI 1.20-6.08) was associated with more severe injury, controlling for resident acuity and other organizational staffing factors. CONCLUSIONS: Most claims were made by care aides and were due to musculoskeletal injuries. In LTC, few worker compensation claims were due to severe injury. More research is needed to delve into the specific features of the LTC setting that are related to worker injury.

Low impact of regular PCR testing on presence at work site during the COVID-19 pandemic: experiences during an open observational study in Lower Saxony 2020-21.

BACKGROUND: Since social distancing during the COVID-19-pandemic had a profound impact on professional life, this study investigated the effect of PCR testing on on-site work. METHODS: PCR screening, antibody testing, and questionnaires offered to 4,890 working adults in Lower Saxony were accompanied by data collection on demographics, family status, comorbidities, social situation, health-related behavior, and the number of work-related contacts. Relative risks (RR) with 95 % confidence intervals were estimated for the associations between regular PCR testing and other work and health-related variables, respectively, and working on-site. Analyses were stratified by the suitability of work tasks for mobile office. RESULTS: Between April 2020 and February 2021, 1,643 employees underwent PCR testing. Whether mobile working was possible strongly influenced the work behavior. Persons whose work was suitable for mobile office (mobile workers) had a lower probability of working on-site than persons whose work was not suitable for mobile office (RR = 0.09 (95 % CI: 0.07 - 0.12)). In mobile workers, regular PCR-testing was slightly associated with working on-site (RR = 1.19 (0.66; 2.14)). In those whose working place was unsuitable for mobile office, the corresponding RR was 0.94 (0.80; 1.09). Compared to persons without chronic diseases, chronically ill persons worked less often on-site if their workplace was suitable for mobile office (RR = 0.73 (0.40; 1.33)), but even more often if their workplace was not suitable for mobile office (RR = 1.17 (1.04; 1.33)). CONCLUSION: If work was suitable for mobile office, regular PCR-testing did not have a strong effect on presence at the work site. TRIAL REGISTRATION: An ethics vote of the responsible medical association (Lower Saxony, Germany) retrospectively approved the evaluation of the collected subject data in a pseudonymized form in the context of medical studies (No. Bo/30/2020; Bo/31/2020; Bo/32/2020).

Ethical leadership supports safety voice by increasing risk perception and reducing ethical ambiguity: Evidence from the COVID-19 pandemic.

Misconduct by business and political leaders during the pandemic is feared to have impacted people's adherence to protective measures that would help to safeguard against the spread of COVID-19. Addressing this concern, this article theorizes and tests a model linking ethical leadership with workplace risk communication-a practice referred to as 'safety voice' in the research literature. Our study, conducted with 511 employees from UK companies, revealed that ethical leadership is positively associated with greater intention to engage in safety voice regarding COVID-19. We also find that this association is mediated by relations with the perceived health risk of COVID-19 and ambiguity about ethical decision making in the workplace. These findings therefore underscore the importance of good ethical conduct by leaders for ensuring that health and safety risks are well understood and communicated effectively by organizational members particularly during crises. We discuss the theoretical and practical implications of our study and highlight further opportunities for future research to address the ethical dimensions of leadership, risk management, and organizational risk communication.

A Distributed IoT Air Quality Measurement System for High-Risk Workplace Safety Enhancement.

The safety of an operator working in a hazardous environment is a recurring topic in the technical literature of recent years, especially for high-risk environments such as oil and gas plants, refineries, gas depots, or chemical industries. One of the highest risk factors is constituted by the presence of gaseous substances such as toxic compounds such as carbon monoxide and nitric oxides, particulate matter or indoors, in closed spaces, low oxygen concentration atmospheres, and high concentrations of CO2 that can represent a risk for human health. In this context, there exist many monitoring systems for lots of specific applications where gas detection is required. In this paper, the authors present a distributed sensing system based on commercial sensors aimed at monitoring the presence of toxic compounds generated by a melting furnace with the aim of reliably detecting the insurgence of dangerous conditions for workers. The system is composed of two different sensor nodes and a gas analyzer, and it exploits commercial low-cost commercially available sensors.

PREVALENCE AND PREDICTORS OF POSTTRAUMATIC STRESS DISORDER, DEPRESSION, AND ANXIETY IN PERSONNEL WORKING IN EMERGENCY DEPARTMENT SETTINGS: A SYSTEMATIC REVIEW.

BACKGROUND: Professionals working in the emergency department (ED) are regularly exposed to traumatic events. Rates of posttraumatic mental health conditions vary widely in the literature and there is no agreement that rates in ED staff are elevated relative to other populations. OBJECTIVE: We conducted a systematic review of international literature reporting prevalence of posttraumatic stress disorder (PTSD), depression, and anxiety in ED personnel to determine whether prevalence is elevated compared to the general community, and to evaluate convergent evidence across the literature for predictive factors. To our knowledge, there is no comprehensive review on this topic in the literature at this time. METHODS: Seven databases were searched for studies reporting rates of PTSD, depression, and anxiety in ED personnel. Two independent researchers screened studies and assessed quality using Munn's Prevalence Critical Appraisal Instrument. Best-evidence synthesis determined whether conditions demonstrated elevated prevalence compared to the general population of Canada, a conservative benchmark. RESULTS: Twenty-four studies from 12 countries and a combined sample size of 4768 were included. PTSD rates ranged from 0% to 23.6% (mean 10.47%), depression ranged from 0.7% to 77.1% (mean 24.8%), and anxiety rates ranged from 2.4% to 14.6% (mean 9.29%). Each condition was elevated compared to the general population. Sociodemographic variables were not consistent predictors. Elevated PTSD seemed most strongly related to workplace exposure and maladaptive coping. CONCLUSIONS: ED professionals have an elevated risk of experiencing PTSD, depression, and anxiety. Identification of organizational and workplace predictors are needed to inform interventions that will reduce risk and provide optimal treatment and management of PTSD, depression, and anxiety in ED settings.

Effect of Hearing and Head Protection on the Localization of Tonal and Broadband Reverse Alarms.

OBJECTIVE: This study explored the effects of hearing protection devices (HPDs) and head protection on the ability of normal-hearing individuals to localize reverse alarms in background noise. BACKGROUND: Among factors potentially contributing to accidents involving heavy vehicles, reverse alarms can be difficult to localize in space, leading to errors in identifying the source of danger. Previous studies have shown that traditional tonal alarms are more difficult to localize than broadband alarms. In addition, HPDs and safety helmets may further impair localization. METHOD: Standing in the middle of an array of eight loudspeakers, participants with and without HPDs (passive and level-dependent) had to identify the loudspeaker emitting a single cycle of the alarm while performing a task on a tablet computer. RESULTS: The broadband alarm was easier to localize than the tonal alarm. Passive HPDs had a significant impact on sound localization (earmuffs generally more so than earplugs), particularly double hearing protection, and level-dependent HPDs did not fully restore sound localization abilities. The safety helmet had a much lesser impact on performance than HPDs. CONCLUSION: Where good sound localization abilities are essential in noisy workplaces, the broadband alarm should be used, double hearing protection should be avoided, and earplug-style passive or level-dependent devices may be a better choice than earmuff-style devices. Construction safety helmets, however, seem to have only a minimal effect on sound localization. APPLICATION: Results of this study will help stakeholders make decisions that are more informed in promoting safer workplaces.

The influence of pandemic-related workplace safety practices on frontline service employee wellbeing outcomes.

The COVID-19 pandemic has exposed the vulnerability of frontline employee (FLEs) to infections and other hazards and highlighted the importance of workplace safety practices (WSP) for service organizations. In response to the critical issue of service safety, we developed and empirically tested a model proposing that WSPs negatively influence FLE perceptions of pandemic related threats and positively influence their perceptions of organizational supportiveness (POS). In turn, these perceptions have time-lagged effects on two aspects of FLE wellbeing-reduced emotional exhaustion and increased work engagement. Utilizing data from a two-wave (separated by a month) survey panel consisting of 310 FLEs across the United States, we found evidence for all hypothesized relationships. We discuss the practical and theoretical implications of our findings and provide suggestions for future research on service safety on the organizational frontlines.

Employment and occupational safety among patients with seizure disorders - findings from a tertiary hospital in Saudi Arabia.

OBJECTIVE: Observational studies suggest that persons with seizure disorders are socially disadvantaged compared to the general population. There are scarce reports in the literature on the prevalence of employment and occupational safety among patients with seizure disorders in Saudi Arabia. We aimed to describe the occupational statuses of patients with seizure disorders and determine factors associated with unemployment. METHODS: This was a cross-sectional study conducted at King Faisal Specialist Hospital and Research Center in Riyadh, Saudi Arabia. Five-hundred-and-forty patients with known seizure disorders or epilepsy who attended neurology and neurosurgery outpatient clinics between January and November 2018 completed a semi-structured questionnaire delivered by interview. RESULTS: Forty-four percent of participants were unemployed (27% of males and 64% of females). Fifteen percent of currently or previously employed participants reported that they had formerly resigned from their job due to their seizure disorder, most commonly as a result of their own fears or concerns. Almost half of the participants reported that their employer made arrangements in the workplace for their seizure disorder, while 18% reported that they did not disclose their diagnosis. Gender, age, and highest educational level were associated with employment status and reason for unemployment. Patients with seizures secondary to trauma were less than half as likely to be employed compared to other participants (aOR = 0.45 95%CI 0.21-0.97, p = 0.042). Holding a driving license increased the odds of being employed (aOR = 2.68 95%CI 1.32-5.46, p = 0.007). Participants on 4 or more antiepileptic medications were more likely to report not being well enough to work. SIGNIFICANCE: Patients with seizure disorders are at increased risk of unemployment, even though many desire work. Unemployment is linked to social factors rather than disease-specific characteristics. Employers in Saudi Arabia generally accommodate patients in the workplace; however, individuals should further be empowered with information on safety in the workplace and their rights to employment.

The Association between the Perceived Adequacy of Workplace Infection Control Procedures and Personal Protective Equipment with Mental Health Symptoms: A Cross-sectional Survey of Canadian Health-care Workers during the COVID-19 Pandemic: L'association entre le caractère adéquat perçu des procédures de contrôle des infections au travail et de l'équipement de protection personnel pour les symptômes de santé mentale. Un sondage transversal des travailleurs de la santé canadiens durant la pandémie COVID-19.

OBJECTIVES: To examine the relationship between perceived adequacy of personal protective equipment (PPE) and workplace-based infection control procedures (ICP) and mental health symptoms among a sample of health-care workers in Canada within the context of the current COVID-19 pandemic. METHODS: A convenience-based internet survey of health-care workers in Canada was facilitated through various labor organizations between April 7 and May 13, 2020. A total of 7,298 respondents started the survey, of which 5,988 reported information on the main exposures and outcomes. Anxiety symptoms were assessed using the Generalized Anxiety Disorder (GAD-2) screener, and depression symptoms using the Patient Health Questionnaire (PHQ-2) screener. We assessed the perceived need and adequacy of 8 types of PPE and 10 different ICP. Regression analyses examined the proportion of GAD-2 and PHQ-2 scores of 3 and higher across levels of PPE and ICP, adjusted for a range of demographic, occupation, workplace, and COVID-19-specific measures. RESULTS: A total of 54.8% (95% confidence interval [CI], 53.5% to 56.1%) of the sample had GAD-2 scores of 3 and higher, and 42.3% (95% CI, 41.0% to 43.6%) of the sample had PHQ-2 scores of 3 and higher. Absolute differences of 18% (95% CI, 12% to 23%) and 17% (95% CI, 12% to 22%) were observed in the prevalence of GAD-2 scores of 3 and higher between workers whose perceived PPE needs and ICP needs were met compared to those who needs were not met. Differences of between 11% (95% CI, 6% to 17%) and 19% (95% CI, 14% to 24%) were observed in PHQ-2 scores of 3 and higher across these same PPE and ICP categories. CONCLUSIONS: Our results suggest strengthening employer-based infection control strategies likely has important implications for the mental health symptoms among health-care workers in Canada.

Estimation of differential occupational risk of COVID-19 by comparing risk factors with case data by occupational group.

BACKGROUND: The disease burden of coronavirus disease 2019 (COVID-19) is not uniform across occupations. Although healthcare workers are well-known to be at increased risk, data for other occupations are lacking. In lieu of this, models have been used to forecast occupational risk using various predictors, but no model heretofore has used data from actual case numbers. This study assesses the differential risk of COVID-19 by occupation using predictors from the Occupational Information Network (O*NET) database and correlating them with case counts published by the Washington State Department of Health to identify workers in individual occupations at highest risk of COVID-19 infection. METHODS: The O*NET database was screened for potential predictors of differential COVID-19 risk by occupation. Case counts delineated by occupational group were obtained from public sources. Prevalence by occupation was estimated and correlated with O*NET data to build a regression model to predict individual occupations at greatest risk. RESULTS: Two variables correlate with case prevalence: disease exposure (r = 0.66; p = 0.001) and physical proximity (r = 0.64; p = 0.002), and predict 47.5% of prevalence variance (p = 0.003) on multiple linear regression analysis. The highest risk occupations are in healthcare, particularly dental, but many nonhealthcare occupations are also vulnerable. CONCLUSIONS: Models can be used to identify workers vulnerable to COVID-19, but predictions are tempered by methodological limitations. Comprehensive data across many states must be collected to adequately guide implementation of occupation-specific interventions in the battle against COVID-19.

Health Care Workers' Reasons for Choosing Between Two Different COVID-19 Prophylaxis Trials in an Acute Pandemic Context: Single-Center Questionnaire Study.

BACKGROUND: In April 2020, two independent clinical trials to assess SARS-CoV-2 prophylaxis strategies among health care workers were initiated at our hospital: MeCOVID (melatonin vs placebo) and EPICOS (tenofovir disoproxil/emtricitabine vs hydroxychloroquine vs combination therapy vs placebo). OBJECTIVE: This study aimed to evaluate the reasons why health care workers chose to participate in the MeCOVID and EPICOS trials, as well as why they chose one over the other. METHODS: Both trials were offered to health care workers through an internal news bulletin. After an initial screening visit, all subjects were asked to respond to a web-based survey. RESULTS: In the first month, 206 health care workers were screened and 160 were randomized. The survey participation was high at 73.3%. Health care workers cited "to contribute to scientific knowledge" (n=80, 53.0%), followed by "to avoid SARS-CoV-2 infection" (n=33, 21.9%) and "the interest to be tested for SARS-CoV-2" (n=28, 18.5%), as their primary reasons to participate in the trials. We observed significant differences in the expected personal benefits across physicians and nurses (P=.01). The vast majority of volunteers (n=202, 98.0%) selected the MeCOVID trial, their primary reason being their concern regarding adverse reactions to treatments in the EPICOS trial (n=102, 69.4%). CONCLUSIONS: Health care workers' reasons to participate in prophylaxis trials in an acute pandemic context appear to be driven largely by their desire to contribute to science and to gain health benefits. Safety outweighed efficacy when choosing between the two clinical trials.
