To examine violence inspections at the Occupational Safety and Health Administration (OSHA).The authors examined all inspections that involved violence against workers begun by January 1, 2019. They conducted semi-structured interviews with compliance officers who had conducted inspections on a sample of facilities that received General Duty Clause (GDC) citations (n = 22) or Hazard Alert Letters (HALs) (n = 22).By January 1, 2019, OSHA initiated 726 "violence" inspections, with 502 (69.1%) in healthcare. In healthcare, 45 (11.1%) resulted in GDC citations and 241 (67.7%) in HALs. GDC facilities received statistically significantly lower scores in 5 of 6 domains examined through semi-structured interviews than HAL facilities. Both groups of facilities had poorly designed recordkeeping systems.Health care facilities continue to generate worker complaints with poorly designed violence prevention programs.

Noise-induced hearing loss (NIHL) represents the second most common occupational disease in the United States. Although the Occupational Safety and Health Administration (OSHA) has promulgated an occupational noise exposure standard and associated recordkeeping requirements, OSHA inspections increasingly document practices that violate both the noise standard and recordkeeping regulation. This article describes five deviations from good clinical practices masking the true societal costs of NIHL, leading to missed prevention opportunities, and creating burdens for individuals and society. These include attributing NIHL to nonoccupational sources, exculpating the workplace because of audiogram patterns without careful documentation, ignoring symptoms or physical examination findings, and simply denying work-relatedness, leading to employers inappropriately lining out cases from the OSHA 300 log. The practices identified by OSHA suggest that many individuals are not following widely recognized and accepted practices when administering hearing conservation programs.

ObjectivesTo characterise heat-related acute kidney injury (HR-AKI) among US workers in a range of industries.MethodsTwo data sources were analysed: archived case files of the Occupational Safety and Health Administration’s (OSHA) Office of Occupational Medicine and Nursing from 2010 through 2020; and a Severe Injury Reports (SIR) database of work-related hospitalisations that employers reported to federal OSHA from 2015 to 2020. Confirmed, probable and possible cases of HR-AKI were ascertained by serum creatinine measurements and narrative incident descriptions. Industry-specific incidence rates of HR-AKI were computed. A capture–recapture analysis assessed under-reporting in SIR.ResultsThere were 608 HR-AKI cases, including 22 confirmed cases and 586 probable or possible cases. HR-AKI occurred in indoor and outdoor industries including manufacturing, construction, mail and package delivery, and solid waste collection. Among confirmed cases, 95.2% were male, 50.0% had hypertension and 40.9% were newly hired workers. Incidence rates of AKI hospitalisations from 1.0 to 2.5 hours per 100 000 workers per year were observed in high-risk industries. Analysis of overlap between the data sources found that employers reported only 70.6% of eligible HR-AKI hospitalisations to OSHA, and only 41.2% of reports contained a consistent diagnosis.ConclusionsWorkers were hospitalised with HR-AKI in diverse industries, including indoor facilities. Because of under-reporting and underascertainment, national surveillance databases underestimate the true burden of occupational HR-AKI. Clinicians should consider kidney risk from recurrent heat stress. Employers should provide interventions, such as comprehensive heat stress prevention programmes, that include acclimatisation protocols for new workers, to prevent HR-AKI.

Background Workers exposed to metalworking fluids (MWF) can develop respiratory illnesses including hypersensitivity pneumonitis (HP). These respiratory manifestations are likely due to microbial contamination of aerosolized MWF. This paper reports a cluster of HP and respiratory symptoms at a manufacturing plant where MWF and workplace air were contaminated with bacterial endotoxin despite frequent negative bacterial cultures of MWF. Methods A pulmonologist assessed and treated three workers with respiratory symptoms. The Occupational Safety and Health Administration (OSHA) inspected the plant. OSHA's investigation included bacterial culture of MWF, measurement of endotoxin concentrations in MWF and workplace air, review of the employer's fluid management program, and distribution of a cross-sectional symptom questionnaire. Results Three workers had biopsy-confirmed HP. In addition, 30.8% of questionnaire respondents reported work-related respiratory symptoms. OSHA detected endotoxin levels as high as 92,000 endotoxin units (EU)/ml in MWF and 3200 EU/m3 in air. Endotoxin concentrations and risk of MWF inhalation were highest near an unenclosed multistation computer numerical control machine. A contractor had tested this machine's MWF for bacterial growth weekly during the preceding three years, and most (96.0%) of those tests were negative. Conclusions Contaminated MWF can cause severe occupational lung disease even if microorganisms do not grow in fluid cultures. Endotoxin testing can increase the sensitivity of detection of microbial contamination. However, employers should not rely solely upon MWF testing data to protect workers. Medical surveillance and meticulous source control, such as engineering controls to suppress MWF mist and prevent its inhalation, can reduce the likelihood of respiratory disease.

Heat stress occupational exposure limits (OELs) were developed in the 1970s to prevent heat-related illnesses (HRIs). The OELs define the maximum safe wet bulb globe temperature (WBGT) for a given physical activity level. This study's objectives were to compute the sensitivity of heat stress OELs and determine if Heat Index could be a surrogate for WBGT. We performed a retrospective analysis of 234 outdoor work-related HRIs reported to the Occupational Safety and Health Administration in 2016. Archived NOAA weather data were used to compute each day's maximum WBGT and Heat Index. We defined the OELs' sensitivity as the percentage of incidents with WBGT OEL. Sensitivity of the OELs was between 88% and 97%, depending upon our assumption about acclimatization status. In fatal cases, the OELs' sensitivity was somewhat higher (92-100%). We also computed the sensitivity of each possible Heat Index discrimination threshold. A Heat Index threshold of 80 °F (26.7 °C) was exceeded in 100% of fatalities and 99% of non-fatal HRIs. In a separate analysis, we created simulated weather data to assess associations of WBGT with Heat Index over a range of realistic outdoor heat conditions. These simulations demonstrated that for a given Heat Index, when radiant heat was included, WBGT was often higher than previously reported. The imperfect correlation between WBGT and Heat Index precluded a direct translation of OELs from WBGT into Heat Index. We conclude that WBGT-based heat stress exposure limits are highly sensitive and should be used for workplace heat hazard assessment. When WBGT is unavailable, a Heat Index alert threshold of approximately 80 °F (26.7 °C) could identify potentially hazardous workplace environmental heat.

We examined relationships between employee safety climate and patient safety culture. Because employee safety may be a precondition for the development of patient safety, we hypothesized that employee safety culture would be strongly and positively related to patient safety culture. An employee safety climate survey was administered in 2010 and assessed employees' views and experiences of safety for employees. The patient safety survey administered in 2011 assessed the safety culture for patients. We performed Pearson correlations and multiple regression analysis to examine the relationships between a composite measure of employee safety with subdimensions of patient safety culture. The regression models controlled for size, geographic characteristics, and teaching affiliation. Analyses were conducted at the group level using data from 132 medical centers. Higher employee safety climate composite scores were positively associated with all 9 patient safety culture measures examined. Standardized multivariate regression coefficients ranged from 0.44 to 0.64. Medical facilities where staff have more positive perceptions of health care workplace safety climate tended to have more positive assessments of patient safety culture. This suggests that patient safety culture and employee safety climate could be mutually reinforcing, such that investments and improvements in one domain positively impacts the other. Further research is needed to better understand the nexus between health care employee and patient safety to generalize and act upon findings.

Objective The aim of this study was to describe risk factors for heat-related illness (HRI) in U.S. workers. Methods We reviewed a subset of HRI enforcement investigations conducted by the Occupational Safety and Health Administration (OSHA) from 2011 through 2016. We assessed characteristics of the workers, employers, and events. We stratified cases by severity to assess whether risk factors were more prevalent in fatal HRIs. Results We analyzed 38 investigations involving 66 HRIs. Many workers had predisposing medical conditions or used predisposing medications. Comorbidities were more prevalent in workers who died. Most (73%) fatal HRIs occurred during the first week on the job. Common clinical findings in heat stroke cases included multiorgan failure, muscle breakdown, and systemic inflammation. Conclusion Severe HRI is more likely when personal susceptibilities coexist with work-related and environmental risk factors. Almost all HRIs occur when employers do not adhere to preventive guidelines.

Heat stress, an environmental and occupational hazard, is associated with a spectrum of heat-related illnesses, including heat stroke, which can lead to death. CDC's National Institute for Occupational Safety and Health (NIOSH) publishes recommended occupational exposure limits for heat stress (1). These limits, which are consistent with those of the American Conference of Governmental Industrial Hygienists (ACGIH) (2), specify the maximum combination of environmental heat (measured as wet bulb globe temperature [WBGT]) and metabolic heat (i.e., workload) to which workers should be exposed. Exposure limits are lower for workers who are unacclimatized to heat, who wear work clothing that inhibits heat dissipation, and who have predisposing personal risk factors (1,2). These limits have been validated in experimental settings but not at outdoor worksites. To determine whether the NIOSH and ACGIH exposure limits are protective of workers, CDC retrospectively reviewed 25 outdoor occupational heat-related illnesses (14 fatal and 11 nonfatal) investigated by the Occupational Safety and Health Administration (OSHA) from 2011 to 2016. For each incident, OSHA assessed personal risk factors and estimated WBGT, workload, and acclimatization status. Heat stress exceeded exposure limits in all 14 fatalities and in eight of 11 nonfatal illnesses. An analysis of Heat Index data for the same 25 cases suggests that when WBGT is unavailable, a Heat Index screening threshold of 85°F (29.4°C) could identify potentially hazardous levels of workplace environmental heat. Protective measures should be implemented whenever the exposure limits are exceeded. The comprehensive heat-related illness prevention program should include an acclimatization schedule for newly hired workers and unacclimatized long-term workers (e.g., during early-season heat waves), training for workers and supervisors about symptom recognition and first aid (e.g., aggressive cooling of presumed heat stroke victims before medical professionals arrive), engineering and administrative controls to reduce heat stress, medical surveillance, and provision of fluids and shady areas for rest breaks.

Despite reports of pulmonary toxicity due to styrene, guidelines on acceptable styrene exposure levels have been based on risk of cancer and central nervous system and liver toxicity and not on respiratory effects. Many reports have linked exposure to styrene vapor in occupational settings to various forms of non-malignant pulmonary disorders including bronchiolitis, hypersensitivity pneumonitis, and occupational asthma. We report two cases in which the same tasks performed in a single workplace resulted in exposure to styrene vapor with subsequent development of acute respiratory symptoms associated with impaired gas exchange and imaging and histopathologic findings consistent with bronchiolitis and organizing pneumonia. Both patients gradually recovered once their workplace exposure to styrene was terminated. Clinicians, employers, and insurers should be aware of the potential for pulmonary toxicity from exposure to styrene.

OBJECTIVE To describe development and validation of the work-related well-being (WRWB) index. METHODS Principal components analysis was performed using Federal Employee Viewpoint Survey (FEVS) data (N = 392,752) to extract variables representing worker well-being constructs. Confirmatory factor analysis was performed to verify factor structure. To validate the WRWB index, we used multiple regression analysis to examine relationships with burnout associated outcomes. RESULTS Principal Components Analysis identified three positive psychology constructs: "Work Positivity", "Co-worker Relationships", and "Work Mastery". An 11 item index explaining 63.5% of variance was achieved. The structural equation model provided a very good fit to the data. Higher WRWB scores were positively associated with all three employee experience measures examined in regression models. CONCLUSIONS The new WRWB index shows promise as a valid and widely accessible instrument to assess worker well-being.

Objective This analysis was conducted to identify industry exposures strongly associated with reports of finger amputation. Methods Reports of severe occupational injuries in the Occupational Safety and Health Administration (OSHA) Severe Injury Report (SIR) database were analyzed in relation to U.S. Census Bureau industry employment data. Industries with significantly elevated reporting odds ratios (RORs) and relative reporting risks (RRRs) were identified. Multiple population association measures including population attributable fraction (PAF) were calculated by industry. Results Among industries with statistically significant RRR and ROR, the poultry processing industry (RRR = 12.60, ROR = 3.37) accounted for the highest PAF by RRR (2.34%) and ROR (1.65%) CONCLUSION:: The results of this analysis identify the poultry processing industry as a leading source of reports of occupational finger amputations and substantiate the need for further collaboration with this industry.

Commercial workplace violence (WPV) prevention training programs differ in their approach to violence prevention and the content they present. This study reviews 12 such programs using criteria developed from training topics in the Occupational Safety and Health Administration’s (OSHA) Guidelines for Preventing Workplace Violence for Healthcare and Social Service Workers and a review of the WPV literature. None of the training programs addressed all the review criteria. The most significant gap in content was the lack of attention to facility-specific risk assessment and policies. To fill this gap, health care facilities should supplement purchased training programs with specific training in organizational policies and procedures, emergency action plans, communication, facility risk assessment, and employee post-incident debriefing and monitoring. Critical to success is a dedicated program manager who understands risk assessment, facility clinical operations, and program management and evaluation.

BACKGROUND:: Federal Employees' Compensation Act injury rates and claim costs benefit from injury prevention and case management efforts. The Department of Labor Protecting Our Workers and Ensuring Reemployment data on lost time injuries and illnesses do support injury prevention and case management activities. METHODS:: The management efforts of the Department of Defense, Veterans Administration, and Department of Labor were examined to determine whether more is needed to support injury prevention and case management efforts. RESULTS:: Data on Protecting Our Workers and Ensuring Reemployment goal 3 metrics should be provided to safety and occupational health (SOH) personnel to support injury prevention and case management efforts. DISCUSSION:: Injury prevention and case management data need to be made available to SOH team members to prevent injuries and lower claims costs. CONCLUSION:: Actionable information must be provided to SOH that will facilitate case management and injury prevention programs and lower costs. Language: en

Objective: The federal workers' compensation program includes under a single employer five commonly encountered roles and responsibilities—injured patient, clinical provider, third-party administrator, adjudicator, and insurer. Data within the Veterans Health Administration (VHA) provide a unique opportunity to apply a simple model of health care quality improvement, exploring interactions between structures, processes, and outcomes. Methods: A facility survey identified reporting structures, levels of education and training, policies and processes, tool availability and use, and perceptions of role adherence. Administrative data included process and outcome metrics, including short-term disability, long-term disability, and lost time cases. Results: Improved collaboration between clinical and administrative staff within VHA and with the Department of Labor was associated with improved performance. Conclusions: Applying a clinical quality improvement model clarifies roles, expectations, and likely relationships for improved program management.

BACKGROUND The Veterans Health Administration undertook a series of performance improvement projects (PIP) using local initiatives identified through a national committee of regional workers' compensation representatives. METHODS A steering committee identified five types of risks and interventions that were considered worthwhile. They defined performance metrics as outcome measures and distinguished short-term from long-term disability management success. RESULTS Eight specific PIPs were implemented. No statistically significant differences in the planned outcome metrics were identified, although cost-benefit evaluations did identify a benefit. CONCLUSIONS Conducting quantitative PIPs in a large system requires top management commitment, sequestration of funds, and mature systems.

Context: In the United States, regional poison centers frequently receive calls about toxic workplace exposures. Most poison centers do not share call details routinely with governmental regulatory agencies. Worker health and safety could be enhanced if regulators such as the Occupational Safety and Health Administration (OSHA) had the ability to investigate these events and prevent similar incidents. With this goal in mind, the Georgia Poison Center (GPC) began referring occupational exposures to OSHA in July 2014. Methods: GPC began collecting additional employer details when handling occupational exposure calls. When workers granted permission, GPC forwarded call details to the OSHA Regional Office in Atlanta. These referrals enabled OSHA to initiate several investigations. We also analyzed all occupational exposures reported to GPC during the study period to characterize the events, detect violations of OSHA reporting requirements, and identify hazardous scenarios that could form the basis for future OSHA rulemaking or guidance. Results: GPC was informed about 953 occupational exposures between 1 July, 2014 and 7 January, 2016. Workers were exposed to 217 unique substances, and 70.3% of victims received treatment in a healthcare facility. Hydrogen sulfide was responsible for the largest number of severe clinical effects. GPC obtained permission to refer 89 (9.3%) calls to OSHA. As a result of these referrals, OSHA conducted 39 investigations and cited 15 employers for “serious” violations. OSHA forwarded several other referrals to other regulatory agencies when OSHA did not have jurisdiction. At least one employer failed to comply with OSHA’s new rule that mandates reporting of all work-related hospitalizations. This collaboration increased OSHA’s awareness of dangerous job tasks including hydrofluoric acid exposure among auto detailers and carbon monoxide poisoning with indoor use of gasoline-powered tools. Conclusions: Collaboration with the GPC generated a useful source of referrals to OSHA. OSHA investigations led to abatement of existing hazards, and OSHA acquired new knowledge of occupational exposure scenarios.

Background Veterans Health Administration (VHA) is a national health care system with variation in hand hygiene (HH) measurement and improvement practices across its facilities. The objective of this national survey was to characterize this variability and identify opportunities for standardization. Methods Survey covered 3 major areas of HH: (1) methods of measuring HH compliance, (2) interventions to improve HH compliance, and (3) site-specific targets for HH compliance. Results One hundred forty-one (100%) VHA medical centers returned the survey. A majority (98.6%) of the medical centers conduct direct observations to measure HH compliance rates. Fewer than half (45.3%) validate the observer process at the onset, and fewer still (39.6%) continue to validate observers. Main behaviors that are considered HH opportunities are room entry (69.1%) and exit (71.9%). Improvement interventions include posters (97.2%), feedback (eg, 98.6% to leadership), and improved access to HH products (eg, 90.6% provide individual hand sanitizers to staff). Mandatory education programs for clinical staff are conducted in 88.5% of the medical centers. The majority of the medical centers (77.3%) set their HH compliance target over 90%. Conclusion Although HH improvement interventions are relatively similar across VHA medical centers, variation exists in compliance monitoring. Findings will assist in standardizing surveillance and next steps in hand hygiene policy in VHA.

To describe a 15-year process creating an industry standard of practice without regulatory support through organizational leadership.Description of the development and rollout of a safe patient-handling program, including the initial scientific development, a cultural history, and agency data.Patient-handling injuries represent more than 20% of injuries to nurses. These declined by more than 40% throughout the program. In parallel, program scope and implementation evolved through collaboration across facility program managers in one organization, among various organizations, and between users and equipment manufacturers. Program success required a shift from a technology focus to culture change and behaviors.Program evolution arises from collaborative practice and interactions between individual practitioners, organizational needs and interests, and manufacturers. Creation of a public forum was critical to changes in a meanwhile internationally accepted standard.

OBJECTIVE: Ascertain whether Veterans Health Administration administrative medical center complexity ratings could be used to help identify potential sites for targeted nursing staff workplace violence intervention activities. PARTICIPANTS: VHA field nursing staff, classified among the nurse, practical nurse, and nursing assistant series, who administratively reported a grand total of 9,964 occupational assault incidents that occurred between October 1, 2003 and September 30, 2011. METHODS: Outcome measures were population-based standardized assault incidence rates, as differentiated by fiscal year, medical facility complexity level, gender, and nursing staff occupation. Subgroup measures included age, highest educational attainment level, location of injury, body part most affected, day of week, and time of day. RESULTS: Across eight fiscal years, standardized incidence rates for reported assaults among females were 6.0 and 2.3 times higher for nursing assistants and practical nurses, respectively, as compared with nurses; for males, the corresponding rates for nursing assistants and practical nurses were 3.5 and 1.5 times higher, respectively. Across occupation and gender, standardized incidence rates for assaults were consistently higher among medium- and low-level facility complexity levels. Findings suggest that more attention is needed for ascertaining the potential role and functioning of facility-specific staff training for preventing assaultive behavior on VHA nursing staff.

The aim of the study was to review the Occupational Safety and Health Administration's (OSHA) 2012 to 2013 heat enforcement cases, using identified essential elements of heat illness prevention to evaluate employers' programs and make recommendations to better protect workers from heat illness.(1) Identify essential elements of heat illness prevention; (2) develop data collection tool; and (3) analyze OSHA 2012 to 2013 heat enforcement cases.OSHA's database contains 84 heat enforcement cases in 2012 to 2013. Employer heat illness prevention programs were lacking in essential elements such as providing water and shade; adjusting the work/rest proportion to allow for workload and effective temperature; and acclimatizing and training workers.In this set of investigations, most employers failed to implement common elements of illness prevention programs. Over 80% clearly did not rely on national standard approaches to heat illness prevention.

Introduction A 2009 Government Accounting Office (GAO) report, along with numerous published studies, documented that many workplace injuries are not recorded on employers' recordkeeping logs required by the Occupational Safety and Health Administration (OSHA) and consequently are under-reported to the Bureau of Labor Statistics (BLS), resulting in a substantial undercount of occupational injuries in the United States. Methods OSHA conducted a Recordkeeping National Emphasis Program (NEP) from 2009 to 2012 to identify the extent and causes of unrecorded and incorrectly recorded occupational injuries and illnesses. Results OSHA found recordkeeping violations in close to half of all facilities inspected. Employee interviews identified workers' fear of reprisal and employer disciplinary programs as the most important causes of under-reporting. Subsequent inspections in the poultry industry identified employer medical management policies that fostered both under-reporting and under-recording of workplace injuries and illnesses. Conclusions OSHA corroborated previous research findings and identified onsite medical units as a potential new cause of both under-reporting and under-recording. Research is needed to better characterize and eliminate obstacles to the compilation of accurate occupational injury and illness data. Practical applications Occupational health professionals who work with high hazard industries where low injury rates are being recorded may wish to scrutinize recordkeeping practices carefully. This work suggests that, although many high-risk establishments manage recordkeeping with integrity, the lower the reported injury rate, the greater the likelihood of under-recording and under-reporting of work-related injuries and illnesses.

To review inhalational exposures and respiratory disease risks in US military personnel deployed to Iraq and Afghanistan and to develop consensus recommendations for medical screening and diagnostic referral.A Working Group of physicians and exposure scientists from academia and from the Departments of Defense and Veterans Affairs was convened in February 2010.Despite uncertainty about the number of people affected and risk factors for adverse pulmonary outcomes in this occupational setting, the Working Group recommended: (1) standardized approaches to pre- and postdeployment medical surveillance; (2) criteria for medical referral and diagnosis; and (3) case definitions for major deployment-related lung diseases.There is a need for targeted, practical medical surveillance for lung diseases and for a standardized diagnostic approach for all symptomatic deployed personnel.

The nature of discomfort and level of exertion associated with wearing respiratory protection in the health care workplace are not well understood. Although a few studies have assessed these topics in a laboratory setting, little is known about the magnitude of discomfort and the level of exertion experienced by workers while they deliver health care to patients for prolonged periods. The purpose of this study was to determine the magnitude of discomfort and level of exertion experienced by health care workers while wearing respiratory protection for periods up to 8 hr when performing their typical occupational duties. This project was a multiple cross-over field trial of 27 health care workers, aged 24-65, performing their typical, hospital-based occupational duties. Each participant served as his/her own control and wore one of seven respirators or a medical mask for 8 hr (or as long as tolerable) with interposed doffing periods every 2 hr. Self-perceived discomfort and exertion were quantified before each doffing: self-perceived level of discomfort using a visual analog scale, and self-perceived level of exertion using a Borg scale. Overall, and as would be expected, discomfort increased over time with continual respirator use over an 8-hr period. Interestingly, exertion increased only marginally over the same time period. The relatively low level of exertion associated with eight respiratory protective devices, including models commonly used in the U.S. health care workplace, is not likely to substantially influence workers' tolerability or occupational productivity. However, the magnitude of discomfort does appear to increase significantly over time with prolonged wear. These results suggest that respirator-related discomfort, but not exertion, negatively influences respirator tolerance over prolonged periods. Discomfort may also interfere with the occupational duties of workers.

OBJECTIVE: : This study examined the relationship between changes in assault rates over time and the implementation of a workplace violence prevention (WVP) program in 138 Department of Veterans Affairs health care facilities. METHODS: : Data on WVP implementation were assessed for each facility by a three-person team. We computed three WVP dimension scores: training, workplace practices, and environmental control and security. We obtained 6 years of assault rate data from the national injury system. Using a linear mixed model, we analyzed whether the WVP implementation was associated with lower assault rates controlling for time and organizational characteristics. RESULTS: : Training implementation was negatively associated with assault rates. Facilities with smaller bed sizes and without academic affiliates had lower assault rates. CONCLUSIONS: : Particular attention should be given to these dimensions because they may be associated with lower facility-level assault rates. Language: en

Facilities with lower complexity had higher vaccination rates. No individual factors were associated with improved performance.Conclusions.Sustained management attention can lead to improvements in healthcare worker influenza vaccination rates. Wavering of attention, though, may lead to rapid loss of effectiveness. Declination statements in this system did not contribute to vaccine acceptance.

This paper evaluates relationships between healthcare employees' perceptions of three hospital organizational constructs (Leadership, Support and Resources), and their assessment of two employee-related outcomes (employee satisfaction and retention) and two patient-related outcomes (patient satisfaction and quality of care). Using four all-employee surveys conducted by the Veterans Health Administration in the United States between 1997 and 2006, we examine the strength of these relationships and their changes over time. Exposure and outcome measures are employee-assessed in all the surveys. Because it can accommodate both latent and measured variables into the model, Structural Equation Modelling (SEM) is used to capture and quantify the relationship structure. The aim of the project is to identify possible intervention foci. The analyses revealed that employee-related outcomes are improved by increases in Leadership and Support, and, not surprisingly, the outcome variable of employee satisfaction reduced turnover intention. The employee assessed patient-related outcomes of satisfaction and quality of care were most improved by increases in Resources. Results also indicate that the three organizational constructs and the web of associations characterized by SEM underwent changes over the study period, perhaps in relation to changes in VHA policy emphases, changes in survey wording and other possible unmeasured factors.

Objective: The study examined the relationship between onsite occupational health practice characteristics, provider choice, and workers' compensation outcome metrics. Methods: Cross-sectional survey of 140 medical center occupational health clinics within the Department of Veterans Affairs. Multivariate regression models examined how specific clinical quality factors influenced provider choice and workers' compensation measures. Results: Several practice characteristics were associated with higher rates of in-house care selection—longer hours of operation, greater availability of workers' compensation–related medical services, clinic administration by a board certified physician, physician tenure, and adherence to clinical practice guidelines. Access to onsite, occupational and environmental medicine certified physician-directed care was associated with reductions in disability duration among injured healthcare workers. Conclusions: These findings suggest that occupational medicine board certification can positively impact provider choice among fully insured patients, which may have implications for other healthcare systems.

PurposeWork‐related musculoskeletal disorders following patient contact represent a major concern for health care workers. Unfortunately, research and prevention have been hampered by difficulties ascertaining true prevalence rates owing to under‐reporting of these injuries. The purpose of this study is to determine the predictors for under‐reporting work‐related musculoskeletal injuries and their reasons.Design/methodology/approachMultivariate analysis using data obtained in a survey of Veterans Administration employees in the USA was used to determine underreporting patterns among registered nurses, licensed practical nurses and nursing assistants. Focus groups among health care workers were conducted at one of the largest Veterans Administration hospitals to determine reasons for under‐reporting.FindingsA significant number of workers reported work‐related musculoskeletal pain, which was not reported as an injury but required rescheduling work such as changing shifts and taking sick leave to recuperate. The findings indicate that older health care workers and those with longer service were less likely to report as were those working in the evening and night shifts. Hispanic workers and personnel who had repetitive injuries were prone to under‐reporting, as were workers in places that lack proper equipment to move and handle patients. Reasons for under‐reporting include the time involved, peer pressure not to report and frustration with workers' compensation procedures.Originality/valueThis study provides insights into under‐reporting musculoskeletal injuries in a major US government organization. The research indicates that current reporting procedures appear to be overtly cumbersome in time and effort. More flexible work assignments are needed to cover staff shortfalls owing to injuries. Health education on the detrimental long‐term effects of ergonomic injuries and the need for prompt attention to injuries should prove useful in improving rates of reporting.

GOALS: The authors examined assault frequency and risk factors in health care. METHODS: The authors conducted a cross-sectional questionnaire survey in 142 hospitals. Analyses are presented at the level of the individual and aggregated by facility. RESULTS: Thirteen percent of employees described at least 1 assault in the last year; the proportion assaulted per facility ranged from 1% to 26%. Patients were the most common assaulters. Working in geriatrics, mental health, and rehabilitation or in nursing represented a high risk for assault. Hours of work and work patterns represented major risk factors for assault, as were higher measures of organizational stress. The penetration of training in alternate dispute resolution strategies was associated with lower rates of assaults. CONCLUSIONS: Although work in health care is associated with high rates of assaults, closer scrutiny suggests specific possible intervention strategies.

Background Hospitals distant from the immediate site of an incident involving a hazardous materials (HAZMATs) release which could include chemical warfare agents, must develop emergency response plans (ERPs) to protect healthcare professionals if they receive potentially contaminated victims. The ERP must address OSHA, EPA, and JCAHO requirements. Methods The VHA convened groups to develop a hazard and exposure assessment, identify actions for compliance with existing regulatory standards, and review site and operational planning issues. Exposure modeling results were used to derive relationships between operational parameters (time and distance from sites/sources) and potential exposure for healthcare workers. Results According to exposure modeling, level C personal protective equipment is adequate to protect hospital staff distant from the chemical release site. Decontamination runoff and contaminated clothing should also be controlled to limit exposure. Conclusions Development and coordination of ERPs must include the local emergency planning committee, with clear assignment of tasks, locations, and training in order to prevent exposures to healthcare workers.

Background This report of the prevalence of latex glove allergy in 3 Department of Veterans Affairs (VA) medical centers was a collaboration of the VA, the Centers for Disease Control and Prevention, and the National Institute for Occupational Safety and Health. Objectives To enroll and evaluate personnel from across the entire hospital workforce for latex hypersensitivity and to determine the type and extent of latex glove use. Methods A questionnaire was administered that covered demographics, job category, latex glove use, and current latex glove allergic symptoms. Skin testing to aeroallergens was performed to evaluate the presence of atopy. Blood was drawn for analyses of serum antilatex IgE antibody by CAP assay. Results Of 1,959 subjects, 158 (8.1%) had latex glove-allergic symptoms, a positive latex CAP assay result, or both. In 1,003 subjects who reported latex glove use, 915 (91.4%) used nonpowdered gloves. A total of 133 subjects reported latex glove allergic symptoms, and 36 subjects had positive CAP assay results. Latex sensitization was correlated with atopy, race, and latex glove exposure. Latex symptoms were correlated with atopy, a positive CAP assay result, and latex glove exposure. Of the 133 subjects with latex glove allergic symptoms, only 11 had positive CAP assay results, giving a prevalence of confirmed latex glove allergy of 0.6%. Conclusions Symptoms attributed to latex gloves and/or latex sensitization occurred in 8.1% of the employee population, with exposure, race, and atopy being the major risk factors. Few symptomatic individuals were sensitized to latex (0.6%). This low rate of confirmed latex glove allergy may have been related to nonpowdered glove use.

The authors describe a longitudinal assessment of intervention effectiveness in response to an outbreak of hypersensitivity pneumonitis (HP) at a metalworking facility. Thirty-five (29%) of the plant's 120 production workers were given a clinical diagnosis of HP during the two years of the investigation. Although quantitative exposure assessment tools were of limited utility, the investigators successfully used qualitative observations and the patients' return-to-work experiences to iteratively evaluate their exposure control recommendations. Recommended interventions included improving metalworking fluid management practices, enclosing selected metalworking fluid machining operations, eliminating mist cooling, exhausting two additional water-based industrial processes, increasing general dilution ventilation, and worker training. As of November 1999, 26 months into the outbreak, 51 percent (18) of the employees with a clinical diagnosis of hypersensitivity pneumonitis had been able to return to work. The symptom onset of the 35 workers who were given a clinical diagnosis of hypersensitivity pneumonitis during the two-year study period predated the implementation of the interventions. The collaboration of a multidisciplinary team appears to have allowed for successful intervention in this setting. A specific etiological agent(s) associated with the outbreak was not confirmed during the investigation. An acid fast isolate identified as being in the Mycobacterium chelonae group was detected in only one of the submitted metalworking fluid (MWF) sump samples. Longitudinally, there was a statistically significant difference in MWF sump bacteria (X(2) = 286.4, df = 17, p.0001) and MWF sump fungi (X(2) = 28.1, df = 7, p.0002). Measured oil mist air levels did not exceed the Occupational Safety and Health Administration's (OSHA's) permissible exposure limit (PEL), and in fact, did not exceed 0.5 mg/m(3).

Objective Occupational and environmental medicine (OEM) physician specialty practices continue to grow in scope and intensity across the Veterans Health Administration. This study characterizes the implementation of a novel, nationwide telemedicine program that provides OEM specialty consultation to providers across the Veterans Health Administration. Methods We examined provider requests and specialist responses for a 6-month pilot from May to October 2013. Characteristics of consult users, determinants of case complexity, and specific applications of OEM specialty expertise were identified. Results Over a 6-month period, employee occupational health providers consulted the OEM telemedicine pilot a total of 65 times. Employee occupational health providers without formal training repeatedly identified complex cases related to work and disability. Conclusions The program has created a new system management solution to deliver expert, in-depth consultation and real-time provider education in OEM.

Indoor microorganism and infection have become an emerging direction in indoor air quality research science. Airborne droplet nuclei can serve as carriers of respiratory infectious diseases. The study of expiratory droplets and their exposure control has received particular attention since the 2003 SARS epidemics and the 2009 influenza pandemics. Little is known about how effective the commonly-used indoor environment control strategies are for infection control. Significant questions also exist on what are the ventilation requirements for airborne infection control. There is a broad range of relevant important issues including the exposure risk, and effective control methods in various indoor settings such as hospitals, homes, schools and offices. What is known is that the minimum required ventilation rate for infection control in hospitals can be much higher than the general health and comfort requirement in homes and offices. This has resulted in significant energy efficiency issues in healthcare facilities. This review considers the current knowledge on airborne transmission of infection and the potential implications of a move to low energy design, particularly in hospitals, on the risk of infection. The review outlines active research and development on reducing hospital energy use while improving infection control and discusses the potential for conducting “clinical trials” to gain the necessary evidence to support changes in hospital ventilation design.

The label "sick building syndrome" is often used to imply the absence of a physiologic basis for symptoms in the built environment. Although building-related illness is widely recognized but considered rare, several well-studied mechanisms may be responsible for many symptoms in buildings. These mechanisms do not explain why some individuals perceive disability. Until researchers distinguish physiologic mechanisms from other aspects of disease and study them systematically, poorly defined symptoms will remain poorly understood. The disability associated with such symptoms and syndromes, not the physiology, is the primary interest and generates controversy.

Background An outbreak of lung disease among workers in a metal-working plant included 16 biopsy-confirmed cases of hypersensitivity pneumonitis and additional patients with asthma, bronchiolitis and emphysema, usual interstitial pneumonitis, and sarcoidosis. Study design Clinical examination of patients; cross-sectional questionnaire survey of the outbreak plant and two control plant areas, one with and one without MWF exposures, in a separate facility; industrial hygiene survey with laboratory characterization of microbial flora; and immunological investigation. Methods Patients with suspected hypersensitivity pneumonitis underwent a clinical examination including detailed lung function, imaging, and tissue studies. A plant walk-through identified metal-working processes, microbial aerosols, and work practices. Microbial characteristics of the three microbial aerosol-producing processes were characterized. Antibodies to those agents were determined in patient sera. A questionnaire survey was conducted in the case plant and in two areas of a control plant, one with and one without metal-working fluids exposure. Results Thirty-nine (79.6%) patients described symptoms consistent with work-related lung disease, eight received other diagnoses, and two did not complete their examinations. Sixteen patients had hypersensitivity pneumonitis confirmed on biopsy. Mean decrements in lung forced expiratory volume in 1 s and force vital capacity from before to after work were similar in the 16 biopsy-confirmed cases of hypersensitivity pneumonitis ( − 6.3%; − 7.2%) and the 19 symptomatic patients without biopsies ( − 11.2%, − 10.1%). Symptoms were more common in the case plant than in a non-MWF control plant area. Three sources of water-based aerosols were identified that grew similar microbial flora. Although machining increased airborne bacterial levels, the increase was not related to the concentration of viable bacteria in the sumps. Antibody testing did not identify a specific single organisms. Endotoxin levels were similar in case and MWF control plant. Conclusions Lung disease in environments with water-based aerosols may be more common than usually recognized. Patients with HP often present with only subtle abnormalities and may be missed if multiple clinical abnormalities are required to document disease. Am. J. Ind.

Medical research facilities, indeed all the nation's constructed facilities, must be designed, operated, and maintained in a manner that supports the health, safety, and productivity of the occupants. The National Construction Goals, established by the National Science and Technology Council, envision substantial improvements in occupant health and worker productivity. The existing research and best practices case studies support this conclusion, but too frequently building industry professionals lack the knowledge to design, construct, operate, and maintain facilities at these optimum levels. There is a need for more research and more collaborative efforts between medical and facilities engineering researchers and practitioners in order to attain the National Construction Goals. Such collaborative efforts will simultaneously support attainment of the National Health Goals. This article is the summary report of the Healthy Buildings Committee for the Leadership Conference: Biomedical Facilities and the Environment sponsored by the National Institutes of Health, the National Association of Physicians for the Environment, and the Association of Higher Education Facilities Officers on 1--2 November 1999 in Bethesda, Maryland, USA.

Soldiers returning from the Gulf War in 1991 described a range of symptoms, including some consistent with the chronic fatigue syndrome, fibromyalgia, and multiple chemical sensitivity. Well-defined adverse health events attributable to service in the Gulf occurred. However, controlled epidemiological studies in Gulf War veterans and controls describe significant excesses of symptoms that were not clearly associated with pathologic disease. At least 12% of veterans currently receive some form of disability from the Department of Veterans Affairs. A number of reports outline theories proposed to explain the excess, but few are scientifically supported. Management guidelines for this spectrum of disorders resembles that of many of "emerging overlap syndromes," including multiple chemical sensitivity, chronic fatigue syndrome, and fibromyalgia. They include the establishment of a trusting doctor-patient relationship, negotiations around a common ground of scientific and etiologic beliefs, non-labeling of the disorder, and work toward recovery in the absence of clear etiologic answers.

The authors conducted a cross-sectional telephone survey of patients and employers to evaluate the effectiveness of conducting industrial hygiene work site visits as part of the medical management of clinic patients with suspected occupational disease. Industrial hygiene interventions were intended to keep the index patient from ongoing exposure while simultaneously protecting co-workers from future disease. The demographics of the 76 work sites and patients are summarized. According to the employers, 78 percent had implemented at least one recommended intervention, and 52 percent of the employers had implemented the priority intervention. The factors associated with the employers' implementation of the recommended industrial hygiene controls are presented. Employers were 3.7 times more likely to implement the priority intervention (p = .04) if they believed a worker's illness was work-related. Employers with joint labor-management health and safety committees were 3.8 times as likely to implement the priority intervention (p = 0.04). The factors associated with changes in the patients' self-reported disease status are explored and the social and economic implications of this model, are discussed. Patients who reported an improvement in disease status were 5.5 times more likely to have maintained or increased their salary (p = 0.03). Patients were 10.4 times more likely to be working if the employer had implemented any intervention (p = 0.02) and 13.3 times more likely if the priority intervention (p = 0.01) had been adopted. Those patients who left their original employer suffered a median decrease in salary of 35 percent if they found work with a different employer and a 90 percent decrease when they failed to find a new job.

The authors present an outbreak of disease associated with exposure to Stachybotrys chartarum and Aspergillus species. A courthouse and two associated office buildings had generated discomfort among employees for two years since initial occupancy. Multiple interventions had been unsuccessful An initial evaluation of 14 individuals identified three with potential asthma and three with symptoms consistent with interstitial lung disease. A clinical screening protocol to identify individuals who should be removed from work identified three likely and seven possible cases of building-related asthma. Detailed environmental and engineering assessments of the building identified major problems in mechanical system design, building construction, and operational strategies leading to excess moisture and elevated relative humidities. Moisture-damaged interior surfaces in both buildings were contaminated with S. chartarum, A. versicolor, and Penicillium species. Aspergillus species, especially A. versicolor, at concentrations of 10(1) to 10(4)/m3 dominated the indoor air under normal operating conditions. Bulk samples also revealed large quantities of Stachybotrys. A questionnaire survey of the three case and two control buildings documented between three- and 15-fold increases in symptoms. A nested case-control study suggested emphysematous-like disease in individuals meeting questionnaire definitions for cases. Replication of analysis strategies used in similar previous investigations suggested an association between worsening symptoms and decreased diffusing capacity of the lung. Performance on neuropsychological measures was similar for both cases and controls, although workers with symptoms reported increased levels of current but not past psychiatric symptomatology. Chemical analyses demonstrated the presence of satratoxins G and H. Cytotoxic laboratory analyses demonstrated the presence of agents with biological effectiveness in bulk materials. No association was seen between IgE or IgG antibodies and the presence of disease. This outbreak represents a likely human response to inhaled fungal toxins in indoor environments. Moisture indoors represents a public health issue currently inadequately addressed by building, health, or housing codes.

Journeymen painters were evaluated with a comprehensive battery of neuropsychological tests and compared to demographically similar nonexposed controls. For painters, a cumulative exposure to solvents was estimated from a structured interview that derived an index based on lifetime exposure and exposure in the past year. Painters were tested either shortly after having painted or after an exposure-free interval. Significant between-group differences were found on a cluster of tests measuring learning and memory. Within the painter group, scores on the learning and memory tests were significantly related to the interaction of condition and exposure. That is, those painters who were tested soon after painting and who also had a higher overall lifetime exposure, performed worst on tests of learning and memory. These results are consistent with the view that neuropsychological function — particularly learning and memory — may be compromised in active workers with a history of chronic solvent exposure. Furthermore, both the chronicity of solvent exposure, as well as the acuteness of the exposure, are significant factors in cognitive performance. (JINS, 1997, 3, 269–275.)

To determine whether a "worksite culture of health" exists within the Veterans Health Administration and implications on integrating employee health promotion programs.Three national surveys were used-an organizational health survey, a health behaviors survey, and a worksite environment survey. Cross-sectional associations between measures of organizational health and employee health behaviors and between measures of organizational health and worksite environment were assessed.There were significant associations between a number of organizational health measures and a combined measure of health behaviors. Likewise, presence of employee-wellness committees and/or coaches was significantly associated with higher appraisal on organizational health measures.Results suggest that a worksite culture of health exists in some but not all facilities within Veterans Health Administration; this has implications for integrating employee health promotion programs systemwide. A phased-in approach is likely warranted.
