Filing a Workers' Compensation Claim for Low Back Pain and Associated Factors: Analysis of 2015 National Health Interview Survey.

OBJECTIVE: The aim of this study was to examine the degree of reporting work-related low back pain (LBP) by workers' compensation (WC) claim filing and associated factors among US workers. METHODS: We conducted multivariable logistic regression using the 2015 National Health Interview Survey data. RESULTS: Among 1203 US workers with self-reported work-related LBP diagnosis, only 19.6% filed for WC. Compared with non-Hispanic White workers, Black, Asian, and Hispanic workers were less likely to file for WC. Workers' compensation filing was less frequent among workers in independent work arrangement and who stopped working, changed jobs, or made a change in work and more frequent among workers 45 to 64 years of age and having high LBP frequency. CONCLUSIONS: Our study findings suggest underreporting of work-related LBP to the WC system is common. Barriers to WC filing should be addressed especially for racial/ethnic minorities and independent workers.

Increased Bloodborne Pathogen Exposure Hotline Utilization During the COVID-19 Pandemic: An Unexpected Phenomenon.

Background: Mitigating bloodborne pathogen exposure (BBPE) risk among healthcare workers is a major focus of hospital-based occupational health programs. The COVID-19 pandemic has placed added demands on occupational health services for healthcare workers. Its impact on BBPE incidence is unreported. Methods: As part of quality improvement efforts, we examined BBPE case incidence at two affiliated health centers during a 24-month period, 12 months preceding and following the COVID-19 pandemic onset. We used Year 1 to Year 2 change in incidence at the larger health center as the referent value to generate predicted incidence rates at the study health center. We tested the ratio of observed to predicted values at the study health center as a Poisson variable to its expectation. We defined a BBPE consistent with the Occupational Safety and Health Administration (OSHA) Bloodborne Pathogens Standard. Results: The BBPE case incidence at Health Center One (HC1), totaled 46 cases in Year 1, increasing 19% to 55 cases in Year 2. The cumulative incidence at Health Center Two (HC2), the referent facility, was 664 cases in Year 1, declining 24% to 503 in Year 2. The ratio of 55 events at HC1 to the expected incidence of 35, based on the experience at HC2, was 1.6 (p < .05). Discussion/Applications to Practice: The incidence of BBPE events at HC1 paradoxically increased during the COVID-19 pandemic, contrasting to the expected decrease that we observed at HC2. These data suggest that during times of increased stress to employee healthcare delivery from an infectious disease outbreak, the burden of ongoing practice demands may increase.

Racial and Ethnic Differences in the Perceptions of Health, Work Environment and Experiences of Work-Related Symptoms Among Cleaning Workers.

This study explored racial and ethnic differences in perception of work environment, safe work practices, general health status, experience of work-related injury or illness and subsequent symptom reporting and health care seeking behaviors among cleaning workers. This study analyzed cross-sectional data obtained from 183 cleaning workers employed in a university hospital or a health sciences campus in Northern California. The sample included 120 Asians (65.6%), 37 Hispanics (20.2%), and 27 other ethnicities (14.2%); 85.7% were foreign-born. Asian workers perceived lower job control and supervisor support and higher job strain than other workers. The odds of perceiving general health as excellent or very good were lower among Asians compared to Hispanics and Others. Asians who experienced chemical-related symptoms were less likely than Hispanics and others to report the symptoms to their supervisor or seek healthcare. Our study findings indicated racial/ethnic differences in perceptions of work and general health, seeking healthcare, and reporting behaviors among cleaning workers. Asian workers, specifically, may need special attention to improve their experiences of work environments and health in the workplace.

Association between household exposure and cycle threshold in COVID-19 infected health care workers.

OBJECTIVE: Household SARS-COV-2 contact constitutes a high-risk exposure for health care workers (HCWs). Cycle threshold (Ct) of reverse transcriptase-polymerase chain reaction testing provides an estimate of COVID-19 viral load, which can inform clinical and workplace management. We assessed whether Ct values differed between HCWs with COVID-19 with and without household exposure. METHODS: We analyzed HCW COVID-19 cases whose Ct data could be compared. We defined low Ct at a cut-point approximating a viral load of 4.6 × 106 copies per ml. Logistic regression tested the association of household exposure and symptoms at diagnosis with a low Ct value. RESULTS: Of 77 HCWs with COVID-19, 20 were household exposures cases and 34 were symptomatic at testing (7 were both household-exposed and symptomatic at testing). Among household exposures, 9 of 20 (45%) manifested lower Ct values compared to 14 of 57 (25%) for all others. In a bivariate model, household exposure was not statistically associated with lower Ct (Odds Ratio [OR] 1.20; 95% Confidence Interval [CI] 0.97-1.51). In multivariable modelling both household exposure (OR] 1.3; 95% CI 1.03-1.6) and symptoms at diagnosis (OR 1.4; 95% CI 1.15-1.7) were associated with a low Ct value. DISCUSSION: Household exposure in HCWs with newly diagnosed COVID-19 was associated with lower Ct values, consistent with a higher viral load, supporting the hypothesis that contracting COVID-19 in that manner leads to a greater viral inoculum.

The Low-Wage Essential Worker: Occupational Concerns and Needs in the COVID-19 Pandemic-A Round Table.

BACKGROUND: Planning occupational health and wellness services and support directed toward low-wage, essential workers in the COVID-19 pandemic has posed a number of challenges across work settings. This article explores the concerns and needs of low-wage essential workers as understood by experts in the field. METHODS: Leading experts in the areas of occupational health and safety, risk management, insurance, and professional education/training were identified and invited to participate in a Round Table discussion. Questions posed to experts were based on literature that addressed COVID-19, essential workers, low-wage workers, infection transmission, education/training, and social justice. FINDINGS: Experts agreed that special considerations must be in place to address the concerns and needs of the low-wage essential worker. These special considerations should address not only the worker's occupational experience but their family and home environment, fears and anxieties, and the economic impact of the COVID-19 restrictions and requirements. CONCLUSION/APPLICATION TO PRACTICE: The occupational health professional is a key resource to employers charged with addressing the concerns and needs of low-wage, essential workers during the COVID-19 pandemic.

"Tennis Leg": A State-of-the-Science Review.

BACKGROUND: Tennis leg (TL), a musculotendon injury to the gastrocnemius, has been associated with the eponymous sport since 1883. This article examines the historical context of TL as a sports compared with an occupational injury. This was juxtaposed with the history of tennis elbow, a tendon injury to the upper extremity also associated with sport. METHODS: Bibliometric databases (PubMed, Web of Science [WOS], Hathi Trust) were keyword-searched; relevant citations were investigated in depth. RESULTS: The search yielded 71 citations for TL (PubMed). The majority (n = 43) were key word linked to sport terms; only one was linked to work-related search terms. Furthermore, none of the top four cited publications (Web of Science) alluded to work-related risk factors in TL in full textual analysis. Hathi Trust yielded the earliest work-related case, reported in a non-biomedical source. Tennis elbow was more frequently reported (n = 189 citations in PubMed) and more frequently linked (n = 193; 9.7%) to occupational search terms. CONCLUSION/APPLICATION TO PRACTICE: The history of TL, juxtaposed with tennis elbow, demonstrates how nosology can influence but does not wholly explain disease attribution, potentially to the detriment of taking into account occupational causality. The lack of recognition of occupational factors revealed in this literature search was notable because TL occurred most commonly in males of working age. By providing perspective on how historical context and nosology can affect the conceptualization of disease, this review may help inform prevention, treatment, and regulatory policy.

Cycle Threshold to Test Positivity in COVID-19 for Return to Work Clearance in Health Care Workers.

OBJECTIVE: To ascertain whether reverse transcriptase polymerase chain reaction (RT-PCR) cycle amplifications until detection, the cycle threshold (Ct), could help inform return to work (RTW) strategies for health care workers (HCWs) recovering from COVID-19 infection. METHODS: Sequential Ct data from COVID-19 nasal pharyngeal (NP) RT-PCR testing in all COVID-19 positive HCWs at a single institution. Analysis of Ct in relation to time until negative testing for RTW clearance. RESULTS: Data for 12 employees showed that time elapsed until RT-PCR test-based RTW clearance ranged from 7 to 57 days (median, 34.5 days). Lower initial Ct correlated with the total time elapsed until clearance (r = -0.80; P = 0.002). CONCLUSION: Considering the RT-PCR Ct, which correlates with the estimated viral load, may help inform RTW planning and decision making beyond solely relying on dichotomized positive/negative results.

Shoulder Injury Related to Vaccine Administration (SIRVA): An Occupational Case Report.

Transient shoulder pain is a common complaint following intramuscular vaccine administration into the deltoid. More severe vaccination-associated shoulder complications comprising of weakness and decreased range of motion are categorized under the construct "shoulder injury related to vaccine administration" (SIRVA) that subsumes both subjective and objective findings consistent with injury. We describe the presentation and management of a case of SIRVA in a health care worker following seasonal influenza vaccine administration as part of a hospital-based employee health program and review the relevant biomedical literature. We present a case from a single medical center. All data were collected by professionals in occupational health by interviewing, performing physical examinations, and reviewing medical records associated with the injured worker. Severe pain and limited range of shoulder motion developed following an influenza vaccination that was administered using a poorly positioned, larger than recommended needle. Magnetic resonance imaging (MRI) demonstrated moderate glenohumeral joint effusion and synovitis, with fluid accumulating in the subscapularis recess within 1 week of injury. At 8 months after initial injury, MRI showed persistent mild tenosynovitis of the long head of the biceps tendon, interval accumulation of a large glenohumeral joint effusion, and infraspinatus tendinitis with subjacent reactive bone marrow edema. The affected worker experienced work restrictions but had no complete lost workdays to date due to the injury. Occupationally related SIRVA is a preventable adverse event that should be considered in workplace vaccine administration programs, and appropriate education and training provided to vaccine administrators to address this.

Off the Courts: Occupational "Tennis Leg".

OBJECTIVE: Injury to the gastrocnemius muscle (tennis leg) is a presenting complaint often associated with athletic pursuits. Despite that label, this form of injury is likely to be common to a variety of salaried and nonsalaried pursuits beyond sports. METHOD: We describe the presentation and management of two cases of "tennis leg" injury occurring in an occupational rather than athletic setting and review the relevant medical literature. RESULTS: Partial tears of the medial insertion of the gastrocnemius tendon were documented in both cases, in the first through magnetic resonance imaging and in the second by ultrasound. CONCLUSION: Rupture of the tendon to the medial head of the gastrocnemius, the so-called "tennis leg" injury, should be considered as potentially work-related trauma, rather than taken to be solely a sports injury.
