Long COVID-ACOEM Guidance Statement.

ABSTRACT: Persistent symptoms are common after acute COVID-19, often referred to as long COVID. Long COVID may affect the ability to perform activities of daily living, including work. Long COVID occurs more frequently in those with severe acute COVID-19. This guidance statement reviews the pathophysiology of severe acute COVID-19 and long COVID and provides pragmatic approaches to long COVID symptoms, syndromes, and conditions in the occupational setting. Disability laws and workers' compensation are also addressed.

Short-acting opioid prescriptions and Workers' Compensation using the National Ambulatory Medical Care Survey.

BACKGROUND: Short-acting opioids have been utilized for pain management with little known about their use in patients on Workers' Compensation (WC) insurance. Our goal was to investigate this association in the ambulatory care setting. METHODS: Using the National Ambulatory Medical Care Survey, visits from patients aged 18-64 during the years 2010 until 2018 were evaluated (excluding 2017 due to data availability). Demographic and co-morbidity data from each visit was obtained along with the visit year. The first short-acting opioid medication prescribed in the database was considered. Survey-weighted frequencies were evaluated. Logistic regression estimated the crude and adjusted odds ratios (OR) with 95% confidence intervals for the use of short-acting opioid prescription. RESULTS: There were 155,947 included visits with 62.5% for female patients. Most patients were White with 11.7% identifying as Black, and 6% identifying as another race. Over 13% of the sample was of Hispanic descent. WC was the identified insurance type in 1.6% of the sample population. Of these patients, 25.6% were prescribed a short-acting opioid, compared with 10.1% of those with another identified insurance. On multivariable regression, Black patients had increased odds of being prescribed a short-acting opioid compared to white patients (OR: 1.22, 95% CI: 1.11-1.34). Those on WC had 1.7-fold higher odds of being prescribed short-acting opioids (95% CI: 1.46-2.06). CONCLUSION: Certain patient characteristics, including having WC insurance, increased the odds of a short-acting opioid prescription. Further work is needed to identify prescribing patterns in specific high-risk occupational groups, as well as to elicit potential associated health outcomes.

Factors associated with COVID-19 vaccine receipt at two integrated healthcare systems in New York City: a cross-sectional study of healthcare workers.

OBJECTIVES: To examine the factors associated with COVID-19 vaccine receipt among healthcare workers and the role of vaccine confidence in decisions to vaccinate, and to better understand concerns related to COVID-19 vaccination. DESIGN: Cross-sectional anonymous survey among front-line, support service and administrative healthcare workers. SETTING: Two large integrated healthcare systems (one private and one public) in New York City during the initial roll-out of the COVID-19 vaccine. PARTICIPANTS: 1933 healthcare workers, including nurses, physicians, allied health professionals, environmental services staff, researchers and administrative staff. PRIMARY OUTCOME MEASURES: The primary outcome was COVID-19 vaccine receipt during the initial roll-out of the vaccine among healthcare workers. RESULTS: Among 1933 healthcare workers who had been offered the vaccine, 81% had received the vaccine at the time of the survey. Receipt was lower among black (58%; OR: 0.14, 95% CI 0.1 to 0.2) compared with white (91%) healthcare workers, and higher among non-Hispanic (84%) compared with Hispanic (69%; OR: 2.37, 95% CI 1.8 to 3.1) healthcare workers. Among healthcare workers with concerns about COVID-19 vaccine safety, 65% received the vaccine. Among healthcare workers who agreed with the statement that the vaccine is important to protect family members, 86% were vaccinated. Of those who disagreed, 25% received the vaccine (p<0.001). In a multivariable analysis, concern about being experimented on (OR: 0.44, 95% CI 0.31 to 0.6), concern about COVID-19 vaccine safety (OR: 0.39, 95% CI 0.28 to 0.55), lack of influenza vaccine receipt (OR: 0.28, 95% CI 0.18 to 0.44), disagreeing that COVID-19 vaccination is important to protect others (OR: 0.37, 95% CI 0.27 to 0.52) and black race (OR: 0.38, 95% CI 0.24 to 0.59) were independently associated with COVID-19 vaccine non-receipt. Over 70% of all healthcare workers responded that they had been approached for vaccine advice multiple times by family, community members and patients. CONCLUSIONS: Our data demonstrated high overall receipt among healthcare workers. Even among healthcare workers with concerns about COVID-19 vaccine safety, side effects or being experimented on, over 50% received the vaccine. Attitudes around the importance of COVID-19 vaccination to protect others played a large role in healthcare workers' decisions to vaccinate. We observed striking inequities in COVID-19 vaccine receipt, particularly affecting black and Hispanic workers. Further research is urgently needed to address issues related to vaccine equity and uptake in the context of systemic racism and barriers to care. This is particularly important given the influence healthcare workers have in vaccine decision-making conversations in their communities.

Proposed Mitigation and Adaptation Strategies Related to Climate Change: Guidance for OEM Professionals.

Climate change is an urgent challenge amplified by socioeconomic factors that demands thoughtful public health responses from OEM professionals. This guidance statement from the American College of Occupational and Environmental Medicine focuses on the different strategies that these health professionals can implement to protect workers from health impacts associated with climate change hazards, foster workplace resilience in the face of rapidly changing environments, and take the necessary steps to mitigate the effects of global climate change.

Factors Associated with SARS-CoV-2 Infection in Physician Trainees in New York City during the First COVID-19 Wave.

Occupational and non-occupational risk factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been reported in healthcare workers (HCWs), but studies evaluating risk factors for infection among physician trainees are lacking. We aimed to identify sociodemographic, occupational, and community risk factors among physician trainees during the first wave of coronavirus disease 2019 (COVID-19) in New York City. In this retrospective study of 328 trainees at the Mount Sinai Health System in New York City, we administered a survey to assess risk factors for SARS-CoV-2 infection between 1 February and 30 June 2020. SARS-CoV-2 infection was determined by self-reported and laboratory-confirmed IgG antibody and reverse transcriptase-polymerase chain reaction test results. We used Bayesian generalized linear mixed effect regression to examine associations between hypothesized risk factors and infection odds. The cumulative incidence of infection was 20.1%. Assignment to medical-surgical units (OR, 2.51; 95% CI, 1.18-5.34), and training in emergency medicine, critical care, and anesthesiology (OR, 2.93; 95% CI, 1.24-6.92) were independently associated with infection. Caring for unfamiliar patient populations was protective (OR, 0.16; 95% CI, 0.03-0.73). Community factors were not statistically significantly associated with infection after adjustment for occupational factors. Our findings may inform tailored infection prevention strategies for physician trainees responding to the COVID-19 pandemic.

Use of Physiological Data From a Wearable Device to Identify SARS-CoV-2 Infection and Symptoms and Predict COVID-19 Diagnosis: Observational Study.

BACKGROUND: Changes in autonomic nervous system function, characterized by heart rate variability (HRV), have been associated with infection and observed prior to its clinical identification. OBJECTIVE: We performed an evaluation of HRV collected by a wearable device to identify and predict COVID-19 and its related symptoms. METHODS: Health care workers in the Mount Sinai Health System were prospectively followed in an ongoing observational study using the custom Warrior Watch Study app, which was downloaded to their smartphones. Participants wore an Apple Watch for the duration of the study, measuring HRV throughout the follow-up period. Surveys assessing infection and symptom-related questions were obtained daily. RESULTS: Using a mixed-effect cosinor model, the mean amplitude of the circadian pattern of the standard deviation of the interbeat interval of normal sinus beats (SDNN), an HRV metric, differed between subjects with and without COVID-19 (P=.006). The mean amplitude of this circadian pattern differed between individuals during the 7 days before and the 7 days after a COVID-19 diagnosis compared to this metric during uninfected time periods (P=.01). Significant changes in the mean and amplitude of the circadian pattern of the SDNN was observed between the first day of reporting a COVID-19-related symptom compared to all other symptom-free days (P=.01). CONCLUSIONS: Longitudinally collected HRV metrics from a commonly worn commercial wearable device (Apple Watch) can predict the diagnosis of COVID-19 and identify COVID-19-related symptoms. Prior to the diagnosis of COVID-19 by nasal swab polymerase chain reaction testing, significant changes in HRV were observed, demonstrating the predictive ability of this metric to identify COVID-19 infection.

The Prescription of Long-Acting Opioids for Working-Age Patients With Workers' Compensation or Chronic Illness Diagnoses in the United States: From the National Ambulatory Medical Care Survey (NAMCS), 2010 to 2016.

OBJECTIVE: To examine associations of workers' compensation, chronic conditions, age, sex, and race/ethnicity with primary prescription of long-acting opioids (LAO) among working-age patients in ambulatory care. METHODS: Using the National Ambulatory Medical Care Survey (2010 to 2016), we conducted descriptive, bivariate, and multivariate logistic regression analyses of patients aged 18 to 64 with an LAO as their primary medication. RESULTS: Those prescribed an LAO were more likely to be men (adjusted odds ratio [aOR] = 1.48, 95% CI 1.13, 1.91), have workers' compensation (aOR = 2.00, 95% CI 1.12, 3.57), or have diagnoses of lower back pain (aOR = 4.70, 95% CI 3.51, 6.29), arthritis (aOR = 1.53, 95% CI 1.11, 2.09), or depression (aOR = 1.69; 95% CI 1.24, 2.31). Hispanic ethnicity/race had a lower likelihood of LAO use compared with non-Hispanic White (aOR = 0.58; 95% CI 0.37, 0.90). CONCLUSIONS: Male sex, workers' compensation, and diagnoses of lower back pain, arthritis, or depression were independently associated with increased LAO prescription odds.

Identifying Acute Low Back Pain Episodes in Primary Care Practice From Clinical Notes: Observational Study.

BACKGROUND: Acute and chronic low back pain (LBP) are different conditions with different treatments. However, they are coded in electronic health records with the same International Classification of Diseases, 10th revision (ICD-10) code (M54.5) and can be differentiated only by retrospective chart reviews. This prevents an efficient definition of data-driven guidelines for billing and therapy recommendations, such as return-to-work options. OBJECTIVE: The objective of this study was to evaluate the feasibility of automatically distinguishing acute LBP episodes by analyzing free-text clinical notes. METHODS: We used a dataset of 17,409 clinical notes from different primary care practices; of these, 891 documents were manually annotated as acute LBP and 2973 were generally associated with LBP via the recorded ICD-10 code. We compared different supervised and unsupervised strategies for automated identification: keyword search, topic modeling, logistic regression with bag of n-grams and manual features, and deep learning (a convolutional neural network-based architecture [ConvNet]). We trained the supervised models using either manual annotations or ICD-10 codes as positive labels. RESULTS: ConvNet trained using manual annotations obtained the best results with an area under the receiver operating characteristic curve of 0.98 and an F score of 0.70. ConvNet's results were also robust to reduction of the number of manually annotated documents. In the absence of manual annotations, topic models performed better than methods trained using ICD-10 codes, which were unsatisfactory for identifying LBP acuity. CONCLUSIONS: This study uses clinical notes to delineate a potential path toward systematic learning of therapeutic strategies, billing guidelines, and management options for acute LBP at the point of care.

Respirator usage protects brain white matter from welding fume exposure: A pilot magnetic resonance imaging study of welders.

Welding fume exposure has been associated with structural brain changes and a wide variety of clinical and sub-clinical outcomes including cognitive, behavioral and motor abnormalities. Respirator use has been shown to decrease exposure to welding fumes; however, the associations between respirator use and health outcomes, particularly neurologic health, have been understudied. In this preliminary study, we used diffusion tensor imaging (DTI) to investigate the effectiveness of respirator use in protecting workers' white matter (WM) from the harmful effects related to welding fume exposure. Fractional anisotropy (FA), a common DTI measurement of water diffusion properties, was used as a marker of WM microstructure integrity. We hypothesized that FA in brain regions involved in motor and neurocognitive functions would differ between welders reporting respirator use compared to those not using a respirator. We enrolled a pilot cohort of 19 welders from labor unions in the New York City area. All welders completed questionnaires to assess welding history and occupational health. All completed a DTI acquisition on a 3 T Siemens scanner. Partial least squares discriminant analysis (PLS-DA), a bioinformatic analytical strategy, was used to model the divergence of WM microstructures in 48 regions defined by the ICBM-DTI-81 atlas between respirator users compared to non-users. This yielded an effective discrimination of respirator users from non-users, with the uncinate fasciculus, the cerebellar peduncle and the superior longitudinal fasciculus contributing most to the discrimination of these groups. These white matter tracts are involved in widespread motor and cognitive functions. To our knowledge, this study is the first to suggest a protective effect of respirator on WM microstructure, indicating that the lack of respirator may present unsafe working conditions for welders. These preliminary findings may inform a larger, longitudinal intervention study that would be more appropriate to investigate the potential protective effect of respirator usage on brain white matter in welders.

Development of a return to work tool for primary care providers for patients with low back pain: A pilot study.

CONTEXT: Low back pain (LBP) is a common cause of disability in adults and primary care physicians (PCPs) are commonly the first medical practitioners to assess these patients. Despite this, PCPs often feel unprepared to make return to work (RTW) recommendations. AIMS: The purpose of our project was to develop RTW guidelines for patients with LBP in the form of an accessible and adaptable electronic medical records (EMR) integrated tool. SETTINGS AND DESIGN: All licensed physicians and physician extenders who see patients over the age of 18 years, presenting with acute LBP who are currently employed were eligible for participation. PCPs were randomized with and without the RTW guidelines and charts were reviewed to assess if PCPs made RTW recommendations. SUBJECTS AND METHODS: RTW guidelines were developed using the Oswestry LBP Disability Questionnaire and the Official Disability Guidelines and integrated into the EMR. STATISTICAL ANALYSIS USED: A Chi-square analysis was used to compare physicians in the interventional and control groups. RESULTS: Forty-four PCPs were randomized into the intervention group and 37 into the control group. In the intervention group, 301 patient encounters met the inclusion criteria for acute LBP. Of these, RTW recommendations were used in 7.3% encounters. Comparatively, there were 256 cases of LBP in the control group and RTW recommendations were offered in 1.6% of encounters (P < 0.001). CONCLUSION: This study showed that PCPs with access to the RTW guidelines in an EMR-integrated tool were significantly more likely to make such recommendations.

Responsibilities of the Occupational and Environmental Medicine Provider in the Treatment and Prevention of Climate Change-Related Health Problems.

: Workers are uniquely susceptible to the health hazards imposed by environmental changes. Occupational and environmental medicine (OEM) providers are at the forefront of emerging health issues pertaining to working populations including climate change, and must be prepared to recognize, respond to, and mitigate climate change-related health effects in workers. This guidance document from the American College of Occupational and Environmental Medicine focuses on North American workers health effects that may occur as a result of climate change and describes the responsibilities of the OEM provider in responding to these health challenges.

Education and Training in Global Occupational Health and Safety: A Perspective on New Pathways to Sustainable Development.

The institution of specific Occupational Health and Safety (OHS) training programs open to international trainees from developing countries in some European, American and Asian universities is now a well-established reality. Courses and seminars that focus particularly on this subject, widely varying in approach and duration, have been held for years at these universities; these academic institutions have combined their potential to attract students from developing countries with the scheduling of interesting lectures and training activities, depending on the availability of funds sufficient to cover travel and lodging costs. Interdisciplinarity is the key to the entire program and is its main strength, as the trainees have the opportunity to condense the technical notions and methodological aspects of different disciplines (occupational health, industrial hygiene, safety management, ergonomics) in one course. We firmly believe that these programs are a precious instrument for the training of occupational health professionals from low-income countries, as they are able to address their choices correctly, hopefully achieving the goal of reducing the human costs of development.

Restaurant Inspection Reports as a Proxy Measure for Occupational Health and Safety: South Asian Restaurant Workers in New York City.

There is a great need to develop workplace health and safety surveillance systems for small businesses to systematically understand the cause, nature, and severity of injuries and illness of their workers. Restaurants can be hazardous workplaces for the nature of the business, materials handled, and tasks completed. Some of the traditional South Asian establishments/restaurants rely heavily on the traditional way of food preparation. Workers in these places may work in less than ideal conditions with minimal or no workplace health and safety regulations or programs. We have explored a unique idea of using NYC's restaurant inspection reports as a possible surveillance tool using the overall restaurant grade and specific violations. Findings show 19% of the Indian, 26% of Bangladeshi, and 15% of Pakistani restaurants did not achieve grade A in these inspections suggesting that around 20% of these restaurants workers are more likely to work in a relatively hazardous or unhygienic working conditions. Using restaurant inspection grade as a proxy measure for employee safety and working conditions may prove to be a useful and practical measure for such an industry.

The market dynamics of selective serotonin re-uptake inhibitors: a private sector study in South Africa.

OBJECTIVE: The objective of this study was to analyse the market share of generic vs originator selective serotonin re-uptake inhibitors (SSRIs), and also compare market share of different SSRIs in the private health care sector in South Africa, over a period of 4 years. METHODOLOGY: This was a retrospective, descriptive study that measured generic market volume as a percentage of the total private SSRI market volume. Retail private sector sales data for six SSRIs available in the private sector in South Africa was evaluated. Sales data were obtained from various stages in the pharmaceutical supply chain, June 2009 - May 2013. RESULTS: Generics constituted 86% and originators 14% of the private sector market volume of SSRIs. The share of the market volume of generic medicines increased by 29.93% over this 4-year period, while an overall increase of 27.86% in the ratio of generics to originators was observed. CONCLUSION: In line with policies, generic SSRIs hold a larger volume of the market in the private sector in South Africa.
