BACKGROUND: With the growth the food service industry and associated high injury and illness rates, there is a need to assess workplace factors that contribute to injury prevention. OBJECTIVE: The objective of this report is to describe the development, application, and utility of a new instrument to evaluate ergonomics and safety for food service workers. METHODS: Starting with a similar tool developed for use in healthcare, a new tool was designed through a collaborative, participatory process with the stakeholders from a collaborating food service company. The new instrument enables the identification and assessment of key safety and health factors through a focused walkthrough of the physical work environment, and structured interviews exploring the organizational work environment. The researchers applied the instrument at 10 of the partnering company's worksites. RESULTS: The instrument identified factors related to both the physical work environment and organizational and contextual environment (e.g., vendor-client relationships) impacting worker safety and health. CONCLUSIONS: Modern assessment approaches should address both the physical and organizational aspects of the work environment, and consider the context complexities in which the worksites and the industry operate.

The true burden (morbidity, mortality, disability, cost, pain, distress) of occupational and work-related diseases and injuries is unknown, and what is reported as burden is significantly underestimated. This underestimation affects the way decision-makers view investments in research and worker protection, which in turn has a substantial impact on national welfare and public health. To better describe the societal and individual burdens of occupational and work-related diseases and injuries, we propose an approach to gauge what is known about burden and where new assessments may be made. This approach consists of 4 elements to consider in burden assessments: (1) utilizing multiple domains, including the individual worker, the worker's family, the community in which the workplace is located, the employer, and society as a whole; (2) taking a broader view of the work-relatedness of disease and injury; (3) assessing the impact of the entire working-life continuum; and (4) applying the comprehensive concept of "well-being" as an indicator in addressing contemporary changes in the nature of work, the workplace, and the workforce. Further research on burden and enhanced surveillance is needed to develop these elements. (Am J Public Health. Published online ahead of print May 18, 2017: e1-e7. doi:10.2105/AJPH.2017.303765).

OBJECTIVE: The aim of this study was to investigate relationships between worksite organizational characteristics (size, industrial sector, leadership commitment, and organizational supports) and integrated approaches to protecting and promoting worker health implemented in smaller enterprises. METHODS: We analyzed web-based survey data of Human Resource Managers at 114 smaller enterprises (<750 employees) to identify organizational factors associated with levels of integrated approaches among their worksites. RESULTS: The companies' mean integration score was 13.6 (SD = 9.6) of a possible 44. In multivariate analyses, having a safety committee (P = 0.035) and top leadership support for health promotion (HP) (P = 0.004) were positively associated with higher integration scores. CONCLUSIONS: Smaller enterprises in one U.S. region have relatively low levels of implementing integrated safety and promotion approaches. Having a safety committee and leadership support for HP may be important contributors to implementing integrated approaches in smaller enterprises.

There is increasing recognition of the value added by integrating traditionally separate efforts to protect and promote worker safety and health. This paper presents an innovative conceptual model to guide research on determinants of worker safety and health and to inform the design, implementation and evaluation of integrated approaches to promoting and protecting worker health. This model is rooted in multiple theories and the premise that the conditions of work are important determinants of individual safety and health outcomes and behaviors, and outcomes important to enterprises such as absence and turnover. Integrated policies, programs and practices simultaneously address multiple conditions of work, including the physical work environment and the organization of work (e.g., psychosocial factors, job tasks and demands). Findings from two recent studies conducted in Boston and Minnesota (2009-2015) illustrate the application of this model to guide social epidemiological research. This paper focuses particular attention on the relationships of the conditions of work to worker health-related behaviors, musculoskeletal symptoms, and occupational injury; and to the design of integrated interventions in response to specific settings and conditions of work of small and medium size manufacturing businesses, based on a systematic assessment of priorities, needs, and resources within an organization. This model provides an organizing framework for both research and practice by specifying the causal pathways through which work may influence health outcomes, and for designing and testing interventions to improve worker safety and health that are meaningful for workers and employers, and responsive to that setting's conditions of work.

OBJECTIVES: To describe (a) a conceptual approach, (b) measurement tools and data collection processes, (c) characteristics of an integrated feedback report and action plan, and (d) experiences of three companies with an integrated measurement approach to worker safety and health. METHODS: Three companies implemented measurement tools designed to create an integrated view of health protection and promotion based on organizational- and individual-level assessments. Feedback and recommended actions were presented following assessments at baseline and 1-year follow-up. Measurement processes included group dialogue sessions, walk-through, online surveys, and focus groups. RESULTS: The approach and measurement tools generated actionable recommendations and documented changes in the physical (eg, safety hazards) and psychosocial (eg, health and safety culture) work environment between baseline and 1-year follow-up. CONCLUSIONS: The measurement tools studied were feasible, acceptable, and meaningful to companies in the SafeWell study.

OBJECTIVE: To conduct validation and dimensionality analyses for an existing measure of the integration of worksite health protection and health promotion approaches. METHODS: A survey of small to medium size employers located in the United States was conducted between October 2013 and March 2014 (N = 115). A survey of Department of Veterans Affairs (VA) administrative parents was also conducted from June to July 2014 (N = 140). Exploratory factor analysis (EFA) was used to determine the dimensionality of the Integration Score in each sample. RESULTS: Using EFA, both samples indicated the presence of one unified factor. The VA survey indicated that customization improves the relevance of the Integration Score for different types of organizations. CONCLUSIONS: The Integration Score is a valid index for assessing the integration of worksite health protection and health promotion approaches and is customizable based on industry. CLINICAL SIGNIFICANCE: The Integration Score may be used as a single metric for assessing the integration of worksite health protection and health promotion approaches in differing work contexts.

In 2009, a preliminary framework for how climate change could affect worker safety and health was described. That framework was based on a literature search from 1988-2008 that supported seven categories of climate-related occupational hazards: (1) increased ambient temperature; (2) air pollution; (3) ultraviolet exposure; (4) extreme weather; (5) vector-borne diseases and expanded habitats; (6) industrial transitions and emerging industries; and (7) changes in the built environment. This paper reviews the published literature from 2008-2014 in each of the seven categories. Additionally, three new topics related to occupational safety and health are considered: mental health effects, economic burden, and potential work safety and health impacts associated with the nascent field of climate intervention (geoengineering). Beyond updating the literature, the paper also identifies key priorities for action to better characterize and understand how occupational safety and health may be associated with climate change events and ensure that worker health and safety issues are anticipated, recognized, evaluated, and mitigated. These key priorities include research, surveillance, risk assessment, risk management, and policy development. Strong evidence indicates that climate change will continue to present occupational safety and health hazards, and this framework may be a useful tool for preventing adverse effects to workers.

OBJECTIVE: To conduct validation analyses for a new measure of the integration of worksite health protection and health promotion approaches developed in earlier research. METHODS: A survey of small- to medium-sized employers located in the United States was conducted between October 2013 and March 2014 (n = 111). Cronbach alpha coefficient was used to assess reliability, and Pearson correlation coefficients were used to assess convergent validity. RESULTS: The integration score was positively associated with the measures of occupational safety and health and health promotion activities/policies-supporting its convergent validity (Pearson correlation coefficients of 0.32 to 0.47). Cronbach alpha coefficient was 0.94, indicating excellent reliability. CONCLUSIONS: The integration score seems to be a promising tool for assessing integration of health promotion and health protection. Further work is needed to test its dimensionality and validate its use in other samples.

OBJECTIVE: We explored associations between organizational factors (size, sector, leadership support, and organizational capacity) and implementation of occupational safety and health (OSH) and worksite health promotion (WHP) programs in smaller businesses. METHODS: We conducted a web-based survey of human resource managers of 117 smaller businesses (<750 employees) and analyzed factors associated with implementation of OSH and WHP among these sites using multivariate analyses. RESULTS: Implementation of OSH, but not WHP activities, was related to industry sector (P = 0.003). Leadership support was positively associated with OSH activities (P < 0.001), but negatively associated with WHP implementation. Organizational capacity (budgets, staffing, and committee involvement) was associated with implementation of both OSH and WHP. Size was related to neither. CONCLUSIONS: Leadership support and specifically allocated resources reflecting that support are important factors for implementing OSH and WHP in smaller organizations.

BACKGROUND: Patient-care workers are frequently exposed to sharps injuries, which can involve the risk of serious illness. Underreporting of these injuries can compromise prevention efforts. METHODS: We linked survey responses of 1,572 non-physician patient-care workers with the Occupational Health Services (OHS) database at two academic hospitals. We determined whether survey respondents who said they had sharps injuries indicated that they had reported them and whether reported injuries were recorded in the OHS database. RESULTS: Respondents said that they reported 62 of 78 sharps injuries occurring over a 12-month period. Only 28 appeared in the OHS data. Safety practices were positively associated with respondents' saying they reported sharps injuries but not with whether reported injuries appeared in the OHS data. CONCLUSIONS: Administrators should consider creating reporting mechanisms that are simpler and more direct. Administrators and researchers should attempt to understand how incidents might be lost before they are recorded.

OBJECTIVE: This study aimed to assess relationships between perceptions of organizational practices and policies (OPP), social support, and injury rates among workers in hospital units. METHODS: A total of 1230 hospital workers provided survey data on OPP, job flexibility, and social support. Demographic data and unit injury rates were collected from the hospitals' administrative databases. RESULTS: Injury rates were lower in units where workers reported higher OPP scores and high social support. These relationships were mainly observed among registered nurses. Registered nurses perceived coworker support and OPP as less satisfactory than patient care associates (PCAs). Nevertheless, because of the low number of PCAs at each unit, results for the PCAs are preliminary and should be further researched in future studies with larger sample sizes. CONCLUSIONS: Employers aiming to reduce injuries in hospitals could focus on good OPP and supportive work environment.

Respiratory problems are common among wildland firefighters. However, there are few studies directly linking occupational exposures to respiratory effects in this population. Our objective was to characterize wildland fire fighting occupational exposures and assess their associations with cross-shift changes in lung function. We studied 17 members of the Alpine Interagency Hotshot Crew with environmental sampling and pulmonary function testing during a large wildfire. We characterized particles by examining size distribution and mass concentration, and conducting elemental and morphological analyses. We examined associations between cross-shift lung function change and various analytes, including levoglucosan, an indicator of wood smoke from burning biomass. The levoglucosan component of the wildfire aerosol showed a predominantly bimodal size distribution: a coarse particle mode with a mass median aerodynamic diameter about 12 mum and a fine particle mode with a mass median aerodynamic diameter < 0.5 mum. Levoglucosan was found mainly in the respirable fraction and its concentration was higher for fire line construction operations than for mop-up operations. Larger cross-shift declines in forced expiratory volume in one second were associated with exposure to higher concentrations of respirable levoglucosan (p < 0.05). Paired analyses of real-time personal air sampling measurements indicated that higher carbon monoxide (CO) concentrations were correlated with higher particulate concentrations when examined by mean values, but not by individual data points. However, low CO concentrations did not provide reliable assurance of concomitantly low particulate concentrations. We conclude that inhalation of fine smoke particles is associated with acute lung function decline in some wildland firefighters. Based on short-term findings, it appears important to address possible long-term respiratory health issues for wildland firefighters. [Supplementary materials are available for this article.

OBJECTIVES: To assess the association between exposure, oxidative stress, symptoms, and cardiorespiratory function in wildland firefighters. METHODS: We studied two Interagency Hotshot Crews with questionnaires, pulse wave analysis for arterial stiffness, spirometry, urinary 8-iso-prostaglandin F2alpha (8-isoprostane) and 8-hydroxy-2'-deoxyguanosine (8-OHdG), and the smoke exposure marker (urinary levoglucosan). Arterial stiffness was assessed by examining levels of the aortic augmentation index, expressed as a percentage. An oxidative stress score comprising the average of z-scores created for 8-OHdG and 8-isoprostane was calculated. RESULTS: Mean augmentation index % was higher for participants with higher oxidative stress scores after adjusting for smoking status. Specifically for every one unit increase in oxidative stress score the augmentation index % increased 10.5% (95% CI: 2.5, 18.5%). Higher mean lower respiratory symptom score was associated with lower percent predicted forced expiratory volume in one second/forced vital capacity. CONCLUSIONS: Biomarkers of oxidative stress may serve as indicators of arterial stiffness in wildland firefighters.

BACKGROUND: The workplace is an important domain for adults, and many effective interventions targeting physical activity and weight reduction have been implemented in the workplace. However, the U.S. workforce is aging, and few studies have examined the relationship of BMI, physical activity, and age as they relate to workplace characteristics. PURPOSE: This paper reports on the distribution of physical activity and BMI by age in a population of hospital-based healthcare workers and investigates the relationships among workplace characteristics, physical activity, and BMI. METHODS: Data from a survey of patient care workers in two large academic hospitals in the Boston area were collected in late 2009 and analyzed in early 2013. RESULTS: In multivariate models, workers reporting greater decision latitude (OR=1.02, 95% CI=1.01, 1.03) and job flexibility (OR=1.05, 95% CI=1.01, 1.10) reported greater physical activity. Overweight and obesity increased with age (p<0.01), even after adjusting for workplace characteristics. Sleep deficiency (OR=1.56, 95% CI=1.15, 2.12) and workplace harassment (OR=1.62, 95% CI=1.20, 2.18) were also associated with obesity. CONCLUSIONS: These findings underscore the persistent impact of the work environment for workers of all ages. Based on these results, programs or policies aimed at improving the work environment, especially decision latitude, job flexibility, and workplace harassment should be included in the design of worksite-based health promotion interventions targeting physical activity or obesity.

OBJECTIVE: To offer a definition of an "integrated" approach to worker health and operationalize this definition using indicators of the extent to which integrated efforts are implemented in an organization. METHODS: Guided by the question-How will we know it when we see it?-we reviewed relevant literature to identify available definitions and metrics, and used a modified Delphi process to review and refine indicators and measures of integrated approaches. RESULTS: A definition of integrated approaches to worker health is proposed and accompanied by indicators and measures that may be used by researchers, employers, and workers. CONCLUSIONS: A shared understanding of what is meant by integrated approaches to protect and promote worker health has the potential to improve dialogue among researchers and facilitate the research-to-practice process.

IMPORTANCE: Understanding the major health problems in the United States and how they are changing over time is critical for informing national health policy. OBJECTIVES: To measure the burden of diseases, injuries, and leading risk factors in the United States from 1990 to 2010 and to compare these measurements with those of the 34 countries in the Organisation for Economic Co-operation and Development (OECD) countries. DESIGN: We used the systematic analysis of descriptive epidemiology of 291 diseases and injuries, 1160 sequelae of these diseases and injuries, and 67 risk factors or clusters of risk factors from 1990 to 2010 for 187 countries developed for the Global Burden of Disease 2010 Study to describe the health status of the United States and to compare US health outcomes with those of 34 OECD countries. Years of life lost due to premature mortality (YLLs) were computed by multiplying the number of deaths at each age by a reference life expectancy at that age. Years lived with disability (YLDs) were calculated by multiplying prevalence (based on systematic reviews) by the disability weight (based on population-based surveys) for each sequela; disability in this study refers to any short- or long-term loss of health. Disability-adjusted life-years (DALYs) were estimated as the sum of YLDs and YLLs. Deaths and DALYs related to risk factors were based on systematic reviews and meta-analyses of exposure data and relative risks for risk-outcome pairs. Healthy life expectancy (HALE) was used to summarize overall population health, accounting for both length of life and levels of ill health experienced at different ages. RESULTS: US life expectancy for both sexes combined increased from 75.2 years in 1990 to 78.2 years in 2010; during the same period, HALE increased from 65.8 years to 68.1 years. The diseases and injuries with the largest number of YLLs in 2010 were ischemic heart disease, lung cancer, stroke, chronic obstructive pulmonary disease, and road injury. Age-standardized YLL rates increased for Alzheimer disease, drug use disorders, chronic kidney disease, kidney cancer, and falls. The diseases with the largest number of YLDs in 2010 were low back pain, major depressive disorder, other musculoskeletal disorders, neck pain, and anxiety disorders. As the US population has aged, YLDs have comprised a larger share of DALYs than have YLLs. The leading risk factors related to DALYs were dietary risks, tobacco smoking, high body mass index, high blood pressure, high fasting plasma glucose, physical inactivity, and alcohol use. Among 34 OECD countries between 1990 and 2010, the US rank for the age-standardized death rate changed from 18th to 27th, for the age-standardized YLL rate from 23rd to 28th, for the age-standardized YLD rate from 5th to 6th, for life expectancy at birth from 20th to 27th, and for HALE from 14th to 26th. CONCLUSIONS AND RELEVANCE: From 1990 to 2010, the United States made substantial progress in improving health. Life expectancy at birth and HALE increased, all-cause death rates at all ages decreased, and age-specific rates of years lived with disability remained stable. However, morbidity and chronic disability now account for nearly half of the US health burden, and improvements in population health in the United States have not kept pace with advances in population health in other wealthy nations.

Injuries are not accidents, so in public health we search for their causes to improve prevention. The best of these efforts seek to identify root causes, avoiding the more limited approach that stops at the level of “the human” responsible for “the error.” Attention is directed to the variety of systems-related determinants that permit or promote human error—a root cause analysis resulting in a robust understanding of injury causality. As these root cause analyses move further upstream past a focus on individuals into systems, cultures, and societies, we have learned that the prevention of the majority of injuries depends much more on understanding organizational rather than individual factors. | The importance of the interaction between the environment and the individual at risk in injury prevention is clear, particularly in the work environment. Advances in understanding and prevention of occupational injuries have resulted in a reduction in reported workplace injuries over the last 20 years in the United States. This suggests that intervention efforts have made a difference, although uncertainties in injury counting, underreporting, transformation to a service-based economy, and increased forms of poorly monitored contract and contingent work affect confidence in true progress.
