Catastrophic injuries and exertional medical events in lacrosse among youth, high school and collegiate athletes: longitudinal surveillance over four decades (1982-2020).

OBJECTIVE: To determine the incidence rates (IRs) of catastrophic injuries and exertional medical events in lacrosse athletes. METHODS: Catastrophic injuries and exertional medical events in lacrosse in the US among youth or amateur, high school and college athletes were analysed from the National Center for Catastrophic Sport Injury Research (NCCSIR) database from 1982/83 to 2019/20. Frequencies, IRs per 100,000 athlete-seasons (AS) with 95% confidence intervals (CIs), and incidence rate ratios (IRRs) with 95% CIs were calculated. Participation data were gathered from the National Federation of State High School Associations (NFHS), National Collegiate Athletic Association (NCAA) and USA Lacrosse. RESULTS: Sixty-nine catastrophic events (16 youth or amateur, 36 high school and 17 college; 84% male) occurred in US lacrosse from 7/1/1982 to 6/30/2020. Thirty-six percent of all incidents were fatal. The overall IR was 0.5 per 100,000 AS (95% CI: 0.4-0.7). There were 15 cases of non-traumatic sudden cardiac arrests (SCAs) and 15 incidents of commotio cordis. Fatality rates from SCA and commotio cordis decreased 95% (IRR = 0.05; 95% CI: 0, 0.2) from 1982/83-2006/07 to 2007/08-2019/20. Incidence rates were higher for collegiate versus high school 1982/83-2019/20 (IRR = 3.2; 95% CI: 1.8, 5.7) and collegiate versus youth 2005/06-2019/20 (IRR = 8.0; 95% CI: 3.0, 21.4) level. Contact with a stick or ball (41%) and contact with another player (20%) were the primary mechanisms of injury. CONCLUSIONS: The incidence of catastrophic events during lacrosse was higher among collegiate than high school or youth athletes. SCA from an underlying cardiac condition or from commotio cordis was the most common catastrophic event. Fatality rates from catastrophic injuries have declined significantly over the study period, perhaps driven by protective measures adopted by lacrosse governing bodies.

Key messagesCollegiate athletes had a higher incidence rate of catastrophic events during lacrosse, while high school athletes had the greatest overall number of events.Cardiac-related events were the most common catastrophic event.Fatality rates for non-traumatic sudden cardiac arrest and commotio cordis have decreased 95% over the past several decades, perhaps related to protective measures and increased access to automated external defibrillators promoted by lacrosse governing bodies.

The Relationship Between Stress and Sleep Sufficiency in the Context of Varied Workplace Social Support.

OBJECTIVE: Sufficient sleep is essential for well-being. We examined the relationship between work-related social support, work stress, and sleep sufficiency, predicting that workers with higher social support would report higher sleep sufficiency across varying levels of work stress. METHODS: The data set analyzed in the present study included 2213 workers from approximately 200 small (<500 employees) businesses in high, medium, and low hazard industries across Colorado. RESULTS: Perceived social support variables moderated the relationship between work stress and sleep sufficiency such that employees reporting higher levels of social support reported higher sleep sufficiency when work stress was low or moderate but not high. CONCLUSIONS: Although preventing work stress is optimal, in cases where employers cannot apply primary interventions to prevent stress (eg, eliminating/reducing night shifts), employers should attempt to increase social support or other more relevant resources for employees.

Pedestrian Safety Among High School Runners: A Case Series.

BACKGROUND: Participation in high school cross-country and track has increased over the last few decades. At the same time, the rate of pedestrian-involved motor vehicle crashes (MVCs) has also increased. In the context of organized sport, pedestrian safety among runners is often not highlighted, despite the risk of catastrophic injury. PURPOSE: To describe incidents of pedestrian-involved MVCs involving student athletes captured by the National Center for Catastrophic Sport Injury Research (NCCSIR) at the University of North Carolina at Chapel Hill. STUDY DESIGN: Case series. LEVEL OF EVIDENCE: Level 5. METHODS: This study utilized surveillance data from the NCCSIR from 2011 to 2020. It presents descriptive statistics, including frequencies and percentages, detailed summaries, and a Haddon Matrix. RESULTS: There were 8 incidents involving 11 student athletes, resulting in 9 fatalities. Of these, 5 cases occurred in the afternoon or early evening, 4 occurred in the Fall, and 6 occurred in a rural area. Haddon Matrix analyses of case descriptions indicate schools should implement a runner safety program for all new runners and ensure that runner safety measures are included in emergency action plans. CONCLUSION: Runner-related MVCs are relatively rare, but tragic, incidents. Pedestrian safety measures should be incorporated into school-sponsored practices and training runs. CLINICAL RELEVANCE: Pedestrian safety should be incorporated into runner safety and injury prevention efforts.

Small + Safe + Well: lessons learned from a Total Worker Health® randomized intervention to promote organizational change in small business.

BACKGROUND: Leadership commitment to worker safety and health is one of the most important factors when organizations develop and implement a Total Worker Health® approach. We aimed to assess the effectiveness of a Total Worker Health ("TWH") leadership development program that targeted owners and other senior-level leadership positions on changing organizational and worker outcomes from baseline to one-year later. METHODS: The Small + Safe + Well study included small businesses from a variety of industries in the state of Colorado, USA that were participating in Health Links™. We designed a randomized waitlisted control comparison design (RCT) to evaluate the added benefit of a TWH leadership development program. An employer assessment tool was used to assess TWH policies and programs, and an employee health and safety survey was used to assess safety leadership and health leadership practices, safety climate and health climate, safety behaviors and health behaviors, and well-being. We used a linear mixed model framework with random effects for business and employee to assess the impact of intervention on the outcomes of interest. RESULTS: Thirty-six businesses (37% retention) and 250 employees (9% retention) met the RCT study inclusion criteria and were included in the analysis. Businesses improved their TWH policies and programs score from baseline to one-year later, regardless of leadership intervention group assignment. Neither intervention group demonstrated improvements in employee-reported outcomes. CONCLUSIONS: This study sought to address a gap in the literature regarding small business senior leadership development for TWH. Our study demonstrates many of the challenges of conducting studies focused on organizational change in workplaces, specifically in small businesses. When designing TWH intervention studies, researchers should consider how to best engage small business leaders in interventions and implementations early on, as well as methods that are well matched to measuring primary and secondary outcomes longitudinally. Future research is needed to test the feasibility and sustainability of TWH interventions in small business. TRIAL REGISTRATION: The trial was retrospectively registered with ClinicalTrials.gov ( ID U19OH011227 ).

Total Worker Health® and Small Business Employee Perceptions of Health Climate, Safety Climate, and Well-Being during COVID-19.

The COVID-19 pandemic created workplace challenges for employee safety and health, especially in small enterprises. We used linear mixed-effects regression to examine changes in health climate, safety climate, and worker well-being, prior to the pandemic and at two timepoints during it. We also examined whether employees at organizations that had received a TWH leadership development intervention prior to COVID-19 would better maintain pre-pandemic perceptions of climates and well-being. The final study cohort consisted of 261 employees from 31 organizations. No differences were observed in mean outcome scores between the leadership intervention groups at any of the survey timepoints. We combined intervention groups to examine the difference across timepoints. Perceptions of health and safety climates remained stable across all timepoints. However, employee well-being scores declined between the pre-pandemic period and subsequent COVID-19 timepoints. These findings suggest that while small organizations continued to be viewed as supporting employees' health and safety over the course of the pandemic, well-being scores declined, indicating that other factors contributed to decreased well-being. The findings from this study have implications for small business leaders as they navigate the impact of the COVID-19 pandemic on the health, safety, and well-being on their organizations and employees.

A pilot study of changes in Total Worker Health® policies and programs and associated changes in safety and health climates in small business.

BACKGROUND: There is little longitudinal research on whether changes to Total Worker Health® (TWH) policies and programs are associated with changes in health climate and safety climate. We hypothesize that as TWH policies and programs change, employees will report changes in safety climate and health climate from baseline to 1 year. METHODS: Twenty-five diverse small businesses and their employees participated in assessments completed approximately 1 year apart. The exposures of interest, TWH policies and programs, were measured using the business-level Healthy Workplace Assessment™ which collects information on six benchmarks. The outcomes of interest, employee perceptions of safety climate and health climate, were measured via an employee survey. We employed paired t-tests and simple linear regression to assess change over a 1-year period. RESULTS: The mean Healthy Workplace Assessment overall score changed by 11.3 points (SD = 11.8) from baseline to Year 1. From baseline to Year 1, the mean scores of each benchmark changed in a positive direction within this sample. The mean safety climate score and health climate score changed by +0.1 points (SD = 0.2) and +0.1 points (SD = 6.4) from baseline to Year 1, respectively. The associations between changes in the overall Healthy Workplace Assessment score and health climate and safety climate scores were negligible [ß = 0.01 (95% confidence interval [CI]: 0.002, 0.02), and ß = 0.01 (95% CI: 0.002, 0.02), respectively]. CONCLUSION: Our study suggests that when small businesses improve upon their TWH policies and programs they experience marginal measurable improvements in employee perceptions of their workplace safety climate and health climate.

Profiles of total worker health® in United States small businesses.

BACKGROUND: The Total Worker Health® (TWH) approach is a best practice method to protect and promote worker safety, health, and well-being. Central to this approach is leadership support and health and safety climates that support day-to-day use of health and safety policies and programs. There is some research that supports these relationships, but there is limited research amongst small businesses. Furthermore, it remains to be shown what role TWH business strategies, as reflected by organizational policies and programs, play in this process. The purpose of this study is to characterize small businesses by their organizations' TWH approach and assess the relationship of these approaches to employee health and safety behaviors. METHODS: We utilized cross-sectional data from 97 businesses participating in the Small+Safe+Well study. We collected data using a business assessment tool, Healthy Workplace Assessment™, and an employee assessment tool, Employee Health and Safety Culture Survey. We used latent profile analysis at the business level to identify subgroups of businesses based on a set of characteristics from these assessments. Linear regression analysis at the employee level was used to determine profile association with employee safety and health behaviors. RESULTS: There were two profiles characterized by the lowest (33% of all businesses) and highest (9%) levels of the indicators. There were also two profiles with higher scores on two of the different foci on either TWH business strategies (27%) or leadership and climate (31%). Employees working for a business with a profile that focused on leadership and climate, in addition to having a business strategy, reported the best safety and health behaviors. CONCLUSIONS: Our study demonstrates that employee engagement in TWH will be highest when businesses have a strategy for how they implement a TWH approach and when they demonstrate leadership commitment to these strategies and foster positive safety and health climates. Our results offer suggestions on how to use TWH assessments to develop interventions for small businesses. More research is needed to understand whether small businesses can improve upon their profile overtime, whether these changes depend on contextual factors, and whether TWH interventions can help them improve their profile.

International Total Worker Health: Applicability to Agribusiness in Latin America.

Total Worker Health® (TWH) is a framework for integrating worker and workplace safety, health, and well-being, which has achieved success in European and US settings. However, the framework has not been implemented in Latin America or in agricultural sectors, leaving large and vulnerable populations underrepresented in the implementation and evaluation of these strategies to improve safety and promote health and well-being. This study presents a case study of how a TWH approach can be applied to a multinational Latin American agribusiness. We describe the process and adaptation strategy for conducting a TWH assessment at multiple organizational levels and in multiple countries. We follow this with a description of a TWH leadership training that was conducted based on the results of the assessment. Finally, we describe our methods to make corporate recommendations for TWH policies and programs that were informed by the TWH assessment and leadership trainings. With this case study we aim to demonstrate the importance and feasibility of conducting TWH in Latin America.

Evaluation of a Total Worker Health® leadership program for small business leaders.

Leaders play a critical role in the development and execution of Total Worker Health (TWH). Small businesses, in particular, can benefit from strong leadership support for TWH as the burden of work-related injury, illness and fatality, as well as poor health and well-being is high in this population. In the present study, we conducted a program evaluation of a TWH leadership development program for small business leaders using the RE-AIM framework. The goal of the program was to help change leaders' behaviors around health, safety and well-being practices following the theory of transformational leadership. Two leaders from each business participated in pre-training activities on their own, a 6-hour in-person training, and three months of access to virtual training transfer activities, including coaching and goal tracking. Our results suggest that the TWH leadership development program is effective at improving leaders' self-reported TWH leadership practices and that the in-person training was implemented successfully. However, leaders did not report improvements in their personal health and in fact reported increased levels of work stress after the program. We also observed some challenges when implementing our training transfer strategies. Our study suggests that leaders may benefit from attending TWH leadership trainings alongside other colleagues in their organization to facilitate a shared vision and goals for TWH in their organization. As a next step, it will be important to determine the program's effectiveness in changing business TWH policies and practices, employee perceptions of TWH and leadership, and employee health and safety outcomes.

The Importance of Small Business Safety and Health Climates During COVID-19.

OBJECTIVE: This study examines employee perceptions of safety and health climates for well-being during the COVID-19 pandemic in a sample of small businesses. METHODS: We evaluated changes to employees' work and home life resulting from COVID-19 and perceptions of safety and health climates. Cross-sectional relationships were assessed using multivariable linear regression models for a sample of 491 employees from 30 small businesses in Colorado in May 2020. RESULTS: Employee perceptions of safety and health climates were significantly related to their self-reported well-being during the first wave of COVID-19, even when there were changes to childcare, the ability to work, and limited social contacts. CONCLUSION: Safety and health climates may influence employee well-being even when other disruptions occur, suggesting that during emergencies, small businesses with strong climates may be better prepared to maintain employee well-being.

Functional Movement Screen as a Predictor of Occupational Injury Among Denver Firefighters.

BACKGROUND: The Functional Movement Screen (FMS™) is a screening tool used to assess an individual's ability to perform fundamental movements that are necessary to do physically active tasks. The purpose of this study was to assess the ability of FMS to predict occupational injury among Denver Fire Department firefighters. METHOD: FMS tests were administered from 2012 to 2016. Claim status was defined as any claim occurrence vs. no claim and an overexertion vs. no claim/other claim within 1 year of the FMS. To assess associations between FMS score and claim status, FMS scores were dichotomized into ≤14 and > 14. Age-adjusted odds ratios were calculated using logistic regression. Sensitivities and specificities of FMS predicting claims at various FMS score cut points, ranging from 10 to 20 were tested. RESULTS: Of 581 firefighters (mean ± SD, age 38 ± 9.8 y) who completed FMS between February 2015 and March 2018, 188 (32.4%) filed a WC claim in the study time frame. Seventy-two of those (38.3%) were categorized as overexertion claims. There was no association between FMS score and claim status [odds ratio (OR) = 1.27, 95% confidence interval (CI): 0.88 - 1.83] and overexertion claim vs. no claim/other claim (OR = 1.33, 95% CI: 0.81 - 2.21). There was no optimal cutoff for FMS in predicting a WC claim. CONCLUSIONS: Although the FMS has been predictive of injuries in other populations, among this sample of firefighters, it was not predictive of a future WC claim.

Total Worker Health Leadership and Business Strategies Are Related to Safety and Health Climates in Small Business.

The purpose of this study was to investigate the relationship between Total Worker Health® (TWH) business strategies and employee perceptions of leadership commitment and safety and health climates. Using data from 53 small enterprises and 1271 of their workers collected as part of the Small + Safe + Well (SSWell) Study, we confirm the primacy of the relationship between leadership commitment to safety and workplace safety climate. After accounting for leadership commitment to safety, business-reported policies and practices that promote the health, safety, and well-being of workers (i.e., TWH strategies) were no longer related to safety climate. In contrast, the relationship between TWH strategies and health climate were significantly associated with the level of small business leadership commitment to worksite wellness. Relatedly, our results demonstrate that leadership is a common correlate to both safety climate and health climate. Future research should investigate integrated TWH leadership development strategies as a means of simultaneously improving safety and health climates.

Evaluation of an Occupational Safety and Health Training for Cannabis Cultivation Workers.

OBJECTIVES: As the commercial cannabis industry grows, there is an increased need to characterize potentially hazardous workplace exposures and provide training to workers to mitigate these exposures with the goal of reducing accidents and injuries from cannabis cultivation, processing, and manufacturing. Public health and safety stakeholders in Colorado developed a worker-focused training designed to improve hazard awareness, recognition, and controls related to commercial cannabis cultivation. This paper describes the evaluation of this training. METHODS: The training was a full day, in-person educational experience directed to workers in the cannabis cultivation industry. Training topics included an overview of occupational safety and health hazards, chemical exposures, slip, trips, and falls, repetitive motion, the application of the hierarchy of control including lockout/tagout, machine guarding, personal protective equipment, among others. Evaluation surveys assessed attendee demographics, perceived job hazards, confidence to change workplace practices, knowledge, training relevancy and quality, intent to change behavior, as well as barriers and resources. RESULTS: A total of 208 people attended the safety trainings. One hundred and thirty-four participants (64%) completed the pre-training survey and 107 (51%) completed the post-training survey. Respondents provided high ratings for the quality and relevance of the training, with 91.3% of respondents rating the training very good or excellent. Before the training, the attendees listed their most concerning safety and health issues as exposure to pesticides and other chemicals (65.7%), absorbing chemicals through the skin (56.7%), slips, trips, and falls (52.2%), and respiratory hazards (50.7%). After the training, they reported the most concerning hazards to be slips, trips, and fall hazards (65.4%), ergonomic problems (64.5%), and respiratory issues (61.7%). There was a statistically non-significant increase in knowledge scores from 67.1% correct to 76.0% correct. Finally, 88.5% of respondents felt extremely or very confident that they could change their own health and safety practices at work. CONCLUSIONS: The training successfully reached cannabis employees in cultivation, compliance, and management. Survey respondents felt that the training was of high quality and addressed gaps in their knowledge related to safety and health hazards in the cannabis industry. The workplace safety and health concerns shifted from pre- to post-training. There was a statistically non-significant increase in knowledge. Additional follow-up of training attendees would be beneficial to measure sustained impact of training.

How does Organizational Climate Motivate Employee Safe and Healthy Behavior in Small Business?: A Self-Determination Theory Perspective.

OBJECTIVE: This study evaluates the motivational processes between employee occupational safety and health climates and behaviors using the Theory of Self-Determination in a sample of diverse small businesses. METHODS: We used cross-sectional data to assess whether employee safety/health intrinsic, identified, and external motives mediate the relationship between safety/health climate and behavior. RESULTS: All three types of motivation mediated the relationship between safety and health climates and behaviors. CONCLUSION: Small businesses seeking to engage employees in Total Worker Health efforts should build strong safety and health climates because of their influence on employees' motivation to participate in health promoting and health protective programs.

Small Business Employees' Perceptions of Leadership Are Associated With Safety and Health Climates and Their Own Behaviors.

OBJECTIVE: Leadership is an important factor in creating a safe and healthy work environment. Little is known about its influence in small organizations. This study assessed the relationship between leadership, climate, and employee behavior in organizations with less than 500 employees. METHODS: We examined organizational factors and worker perceptions of leadership and safety/health behaviors in an analysis of 1271 employees in 53 Colorado small organizations. Cross-sectional relationships were assessed using multivariable linear regression models. RESULTS: Perceived leadership commitment to safety was associated with safety climate (ß = 0.67) and safety behaviors among employees (ß = 0.45). Perceived leadership commitment to worksite wellness was associated with health climate (ß = 0.66) and health behaviors (ß = 0.42). CONCLUSIONS: Leadership plays an important role in creating a positive work environment around safety and health.

Physical Activity Opportunities and Academic Outcomes of Fourth Grade Elementary School Students in Georgia.

BACKGROUND: Physical activity at schools is an important component in combatting childhood obesity. Studies have shown that physical activity at school is positively associated with academic outcomes. The purpose of this study is to examine associations between opportunity of physical activity time at school and academic outcomes. METHODS: This statewide, cross-sectional study utilized 2 data sources from the Georgia Department of Education and Georgia Shape in 860 schools. Multivariable linear regression analysis assessed the impact of the amount of physical activity time at school and standardized test scores, controlling for aerobic capacity, BMI, race, gender, school size, geographic category, and SES. RESULTS: Time of physical activity opportunity at school was not significantly associated with Mathematics or Reading CRCT scores (p = .94, p = .31, respectively). SES had the greatest impact on test scores, where higher SES schools had higher standardized test scores (p < .01 for all tests scores). CONCLUSION: Time of physical activity opportunities at school was not significantly associated with standardized test scores. SES appears to be the most important factor in academic outcomes. Time spent in PA at school does not negatively affect academic outcomes and should be utilized to prevent/reduce childhood overweight and obesity.

The impact of industry and body part injured on repeat workers' compensation claims.

BACKGROUND: Few studies investigate the influence of body part injured and industry on future workers' compensation claims. METHODS: Using claims incurred from 1 January 2005 to 31 July 2015 (n = 77 494) from the largest workers' compensation insurer in Colorado, we assessed associations between worker characteristics, second claims involving any body part and the same body part. We utilized Cox proportional hazards models to approximate the probability of a second claim. RESULTS: First claims represented 74.9% (n = 58 007) and second claims 25.2% (n = 19 487) of total claims. Sex, age, industry, and body part of the first claim were associated with the probability of second claims and the body part affected. The 5-year probabilities of second claims and same body part second claims were 27.0% (95% confidence interval [CI]: 26.6%-27.5%) and 6.2% (95% CI: 5.9%-6.5%) in males and 26.5% (95% CI: 26.0%-27.0%) and 6.7% (95% CI: 6.5%-7.0%) in females. Most second claims occurred within 3 years. CONCLUSIONS: Most second claims occur within 3 years. Body part and industry-specific injury patterns suggest missed opportunities for prevention.

Highlights from occupational safety and health continuing education needs assessment.

BACKGROUND: There is a lack of trained Occupational Safety and Health (OSH) professionals able to meet the current and future demand for such expertize in the United States. Many OSH professionals are required to perform duties, which are outside of their primary area of expertize; thus, expansion of continuing education (CE) may be necessary to properly train individuals for new OSH responsibilities. METHODS: The National Institute for Occupational Safety and Health-funded Education and Research Centers collectively developed and distributed an internet-based survey to gauge the CE needs and interests of the OSH workforce. RESULTS: A total of 2064 responses were received. The most common primary professions represented were safety (28%), occupational health nursing (18%), and industrial hygiene (12%). The majority of respondents (61%) reported that they perform work activities outside of those associated with their primary OSH profession. The CE offerings with the highest interest among respondents were related to safety. Other courses with high levels of interest included topics such as legal issues in OSH (88%), compliance (88%), risk management (85%), OSH management (83%), risk communication (83%), and communication in accident prevention (81%). Health and safety leadership (82%), health and safety culture (78%) and total worker health (74%) were also significant interests. CONCLUSIONS: It is important to be responsive to the evolving needs of the OS&H community. Developing relevant courses will help ensure that OS&H professionals have access to the training they need to perform essential job functions and keep employees healthy and safe.

Reoccurring Injury, Chronic Health Conditions, and Behavioral Health: Gender Differences in the Causes of Workers' Compensation Claims.

OBJECTIVE: The aim of this study was o examine how work and nonwork health-related factors contribute to workers' compensation (WC) claims by gender. METHODS: Workers (N = 16,926) were enrolled in the Pinnacol Assurance Health Risk Management study, a multiyear, longitudinal research program assessing small and medium-sized enterprises in Colorado. Hypotheses were tested using gender-stratified logistic regression models. RESULTS: For both women and men, having incurred a prior WC claim increased the odds of a future claim. The combination of incurring a prior claim and having metabolic health conditions resulted in lower odds of a future claim. Behavioral health risk factors increased the odds of having a claim more so among women than among men. CONCLUSION: This study provides data to support multifactorial injury theories, and the need for injury prevention efforts that consider workplace conditions as well as worker health.

Small business Total Worker Health: A conceptual and methodological approach to facilitating organizational change.

Nearly half of Americans are employed by small businesses, and future projections suggest that the number of those employed by small businesses will rise. Despite this, there is relatively little small business intervention research on the integration of health protection and health promotion, known as Total Worker Health® (TWH). We first discuss the importance of studying small businesses in TWH research and practice. Second, we describe an example of a small business TWH intervention, Health Links™ plus TWH owner/senior manager leadership training, that we are evaluating via the Small+Safe+Well (SSWell) study. Key features of the intervention and the SSWell study include attention to multi-level influences on worker health, safety and well-being; organizational change; and dissemination and implementation science strategies via the RE-AIM model. We offer several considerations for future small business TWH research and practice both in terms of the small business context as well as intervention development and evaluation. Our goal is to provide TWH researchers and practitioners with a framework and an example of how to approach small business TWH interventions. Ultimately, through the SSWell study, we aim to provide small businesses with strong evidence to support the use of TWH strategies that are practical, effective and sustainable.
