Descriptive summary of fatal work-related injuries, Western States, 2011-2017.

Work-related deaths are a persistent occupational health issue that can be prevented. However, prevention opportunities can be hampered by a lack of adequate public health resources. The Western States Occupational Network (WestON) is a network of federal, state, and local occupational health professionals that includes a 19-state region of the United States. To encourage public health collaboration, WestON partners examined work-related fatalities within the region. Fatality counts (numerators) were obtained from the U.S. Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries restricted-access research files for all workers ages ≥15 years and fatally injured in WestON states from 2011 through 2017. Estimates of full-time equivalent hours worked (FTE) (denominators) were retrieved from the BLS Current Population Survey. Annual average fatality rates were calculated as number of fatalities per 100,000 FTE over the study period. Rates were stratified by state, select demographics, industry sector, and event/exposure types. Pearson chi-squared tests and rate ratios with 95% confidence probability limits were used to assess rate differences. All analyses were conducted using SAS v.9.4. From 2011 through 2017, the annual average overall occupational fatality rate for the WestON region was 3.5 fatalities per 100,000 FTE, comparable to the overall U.S. fatality rate. Male workers had a fatality rate almost 10 times higher than female workers in the region. Fatality rates increased with successive age groups. Alaska and New Mexico had significantly higher fatality rates for all racial/ethnic groups compared to respective regional rates. Wyoming, North Dakota, and Montana had the three highest occupational fatality rates among foreign-born workers. Agriculture/forestry/fishing, mining/oil/gas extraction, and transportation/warehousing/utilities were industry sector groups with the three highest fatality rates regionally. Transportation-related incidents were the most frequent event type associated with occupational fatalities for all 19 states. Work-related fatalities are a crosscutting occupational public health priority. This analysis can be an impetus for collaborative multistate initiatives among a dynamic and varied occupational public health network to better meet the needs of a rapidly changing workforce.

Occupation and Industry Data Quality Among Select Notifiable Conditions in Washington State.

CONTEXT: Occupation and industry are basic data elements that, when collected during public health investigations, can be key to understanding patterns of disease transmission and developing effective prevention measures. OBJECTIVE: To assess the completeness and quality of occupation and industry data among select notifiable conditions in Washington and discuss potential improvements to current data collection efforts. DESIGN: We evaluated occupation and industry data, collected by local health departments during routine case investigations, for 11 notifiable conditions, selected for inclusion based on an established or plausible link to occupational exposure. SETTING AND PARTICIPANTS: Confirmed cases of select notifiable conditions among Washington residents aged 16 to 64 years, for years 2019-2021. MAIN OUTCOME MEASURES: We calculated the percentage of cases among working-age adults reported as employed, the percentage with occupation and industry data collected, and the percentage assigned standard occupation and industry codes. We identified the most common responses for occupation and industry and challenges of assigning codes to those responses. RESULTS: Among the 11 conditions evaluated, one-third of cases aged 16 to 64 years were reported as employed. Among the cases reported as employed, 91.5% reported occupation data and 30.5% reported industry data. "Self-employed" was among the top responses for occupation, a response that does not describe a specific job and could not be assigned an occupation code. In the absence of additional information, 4 of the most common responses for industry could not be coded: "health care," "technology," "tech," and "food." CONCLUSION: Routine collection of informative occupation and industry data among working-age adults is largely absent from case investigations in Washington. Methods of data collection that improve quality while minimizing the burden of collection should be pursued. Suggestions for improving data quality are discussed.

Racial and ethnic disparities in workers' compensation claims rates.

BACKGROUND: Workers of color experience a disproportionate share of work-related injuries and illnesses (WRII), however, most workers' compensation systems do not collect race and ethnicity information, making it difficult to monitor trends over time, or to investigate specific policies and procedures that maintain or could eliminate the unequal burden of WRII for workers of color. The purpose of this study is to apply a Bayesian method to Washington workers' compensation claims data to identify racial and ethnic disparities of WRII by industry and occupation, improving upon existing surveillance limitations. Measuring differences in risk for WRII will better inform prevention efforts and target prevention to those at increased risk. METHODS: To estimate WRII by race/ethnicity, we applied the Bayesian Improved Surname Geocode (BISG) method to surname and residential address data among all Washington workers' compensation claims filed for injuries in 2013-2017. We then compare worker and injury characteristics by imputed race/ethnicity, and estimate rates of WRII by imputed race/ethnicity within industry and occupation. RESULTS: Black/African Americans had the highest rates of WRII claims across all industry and occupational sectors. Hispanic/Latino WRII claimants also had higher rates than Whites and Asian/Pacific Islanders in almost all industry and occupational sectors. For accepted claims with both medical and non-medical compensation, Bodily reaction/overexertion injuries accounted for almost half of the claims during this reporting period. DISCUSSION: The high rates of injury we report by racial/ethnic categories is a cause for major concern. Nearly all industry and occupation-specific rates of workers' compensation claims are higher for Black/African American and Hispanic/Latino workers compared to Whites. More work is needed to identify work-related, systemic, and individual characteristics.

Are plumbing apprentice graduates safer than their non-apprentice peers? Workers' compensation claims among journey level plumbers by apprenticeship participation.

INTRODUCTION: Apprenticeships combine mentored on-the-job training with related instruction to develop a workforce with the skills sought by employers. Workplace safety is an important component of apprenticeship training. Whether that training results in fewer work injuries, however, is largely unknown. METHOD: We linked Washington's registered apprenticeship data, plumber certification (licensing) data, employment data, and workers' compensation claims to compare claim rates among journey level plumbers (JLP) by apprenticeship participation. We used negative binomial regression models to estimate rates of total claims, wage replacement/disability claims, acute injuries, and musculoskeletal disorders (MSD), adjusted for worker characteristics. RESULTS: Among JLP certified between 2000 and 2018, rates among JLP with no apprenticeship training were 46% higher for total workers' compensation claims (adjusted Rate Ratio (aRR) = 1.46, 95% CI: 1.26-1.69) and 60% higher for wage replacement/disability claims (aRR = 1.60, 95% CI: 1.22-2.11), compared to rates among JLP who completed a plumbing apprenticeship. Apprentice graduates experienced a greater decline in the rate of total claims between the 5 years preceding JLP certification and the years after certification (55.3% vs. 41.4% among JLP with no apprenticeship training). Greater rate reductions among JLP apprentice graduates were also observed for acute injuries and MSD, although the decline in MSD was not significantly different from the decline among JLP with no apprenticeship training. CONCLUSIONS: Successful completion of a plumbing apprenticeship program is associated with fewer work injuries throughout the career of a JLP. Apprenticeships appear to play a key role in reducing work injuries among JLP, especially acute injuries. PRACTICAL APPLICATIONS: Apprenticeships are an effective model for reducing workplace injuries. The mechanisms by which apprenticeship training improves workplace safety should be identified to better inform injury prevention efforts among apprentices as well as among workers outside of a formal apprenticeship arrangement.

Heat related illness among workers in Washington State: A descriptive study using workers' compensation claims, 2006-2017.

BACKGROUND: Heat related illness (HRI) places a significant burden on the health and safety of working populations and its impacts will likely increase with climate change. The aim of this study was to characterize the demographic and occupational characteristics of Washington workers who suffered from HRI from 2006 to 2017 using workers' compensation claims data. METHODS: We used Washington workers' compensation data linked to weather station data to identify cases of work-related HRI. We utilized Occupational Injury and Illness Classification System codes, International Classification of Diseases 9/10 codes, and medical review to identify accepted and rejected Washington State (WA) workers' compensation claims for HRI from 2006 to 2017. We estimated rates of HRI by industry and evaluated patterns by ambient temperature. RESULTS: We detected 918 confirmed Washington workers' compensation HRI claims from 2006 to 2017, 654 were accepted and 264 were rejected. Public Administration had the highest third quarter rate (131.3 per 100 000 full time employees [FTE]), followed by Agriculture, Forestry, Fishing, and Hunting (102.6 per 100 000 FTE). The median maximum daytime temperature was below the Washington heat rule threshold for 45% of the accepted HRI claims. Latinos were estimated to be overrepresented in HRI cases. CONCLUSION: The WA heat rule threshold may not be adequately protecting workers and racial disparities are present in occupational HRI. Employers should take additional precautions to prevent HRI depending on the intensity of heat exposure. States without heat rules and with large industry sectors disproportionately affected by HRI should consider regulations to protect outdoor workers in the face of more frequent and extreme heat waves.

Fewer workers' compensation claims and lower claim costs if employers with high injury rates achieved the rates of their safer peers.

INTRODUCTION: Employers engaged in similar business activities demonstrate a range of workers' compensation claim rates. Workplace injuries and illnesses could be prevented if employers with high claim rates achieved the claim rates of their safer peers. METHODS: We used Washington workers' compensation claims data for years 2013-2015 to calculate rates of compensable claims (eligible for disability or time loss benefits, if unable to work four days after injury) and total accepted claims (compensable plus medical-aid only claims) for each employer. We estimated the number and cost of claims to occur if employers with high claim rates reduced them to the rates of employers at the 25th percentile, adjusted for insurance risk class, employer size, and injury type. To evaluate the impact of setting more or less ambitious goals, we also estimated reductions based on claim rates at the 10th and 50th percentiles. RESULTS: Over 43% of claims and claim costs would be prevented if employers with higher claim rates lowered them to the 25th percentile using either total accepted or compensable claim rates as the benchmark outcome. The estimated claim cost savings from benchmarking to compensable claims was nearly as great as the estimate based on benchmarking to total accepted claims ($308.5 mil annually based on compensable claims vs. $332.4 mil based on total accepted claims). Restaurants and Taverns had the greatest number of potentially prevented compensable claims. Colleges and Universities and Wood Frame and Building Construction had the greatest potential reduction in compensable claim costs among larger and smaller employers, respectively. CONCLUSION: Substantial reductions in workers' compensation claims and costs are possible if employers achieve the injury rates experienced by their safer peers. Practical application: Evaluating the range of workplace injury rates among employers within industry groups identifies opportunities for injury prevention and offers another approach to resource allocation.

Injury Rate Comparisons for Nonmechanized and Mechanized Logging Operations, Washington State, 2005-2014.

OBJECTIVES: Current industry classification systems in the United States do not differentiate mechanized and nonmechanized logging operations. The objectives of this article are to quantify injury risk differences between mechanized and nonmechanized logging operations in Washington State and to evaluate for potential injury risk tradeoffs, such as decreasing traumatic injuries while increasing nontraumatic injuries that might occur when mechanized logging operations are substituted for nonmechanized logging operations. METHODS: Using Washington State workers' compensation insurance risk classes to differentiate mechanized and nonmechanized logging operations, injury and illness claims data and employer reported hours were used to compare claim rates and to characterize injuries by type of logging operation. RESULTS: From 2005 to 2014, the accepted Washington State worker's compensation claim rate for nonmechanized logging was 46.4 per 100 full-time equivalent employees compared to 6.7 per 100 full-time equivalent (FTE) for mechanized logging activities. The rate ratio for comparing nonmechanized to mechanized logging claims rates for all accepted claims was 6.9 (95% Confidence Interval 6.4-7.5). Claim rates for traumatic injury and nontraumatic injuries in nonmechanized logging exceeded comparable rates in mechanized logging activities, although the distribution of types of injury differed by type of logging operation. A greater percentage of accepted claims in nonmechanized logging were traumatic injuries than in mechanized logging (92.2% vs. 85.0%, respectively). In addition, nonmechanized logging had higher total claim and medical costs per FTE and had a higher proportion of claims with lost work time than mechanized logging. CONCLUSION: Mechanized logging offers a considerable safety advantage over nonmechanized logging operations. Continued efforts to increase the mechanization of logging operations will result in decreased injury rates.

Employer knowledge of federal requirements for recording work-related injuries and illnesses: Implications for occupational injury surveillance data.

BACKGROUND: Accuracy of the Bureau of Labor Statistics Survey of Occupational Injuries and Illnesses (SOII) data is dependent on employer compliance with workplace injury and illness recordkeeping requirements. Characterization of employer recordkeeping can inform efforts to improve the data. METHODS: We interviewed representative samples of SOII respondents from four states to identify common recordkeeping errors and to assess employer characteristics associated with limited knowledge of the recordkeeping requirements and non compliant practices. RESULTS: Less than half of the establishments required to maintain OSHA injury and illness records reported doing so. Few establishments knew to omit cases limited to diagnostic services (22%) and to count unscheduled weekend days as missed work (27%). No single state or establishment characteristic was consistently associated with better or worse record-keeping. CONCLUSION: Many employers possess a limited understanding of workplace injury recordkeeping requirements, potentially leading them to over-report minor incidents, and under-report missed work cases.

Workers' compensation claims not reported in the Survey of Occupational Injuries and Illnesses: Injury and claim characteristics.

BACKGROUND: Underreporting in the nation's primary source of non-fatal occupational injury and illness data are well documented, but worker-level characteristics of unreported cases have not been fully explored. METHODS: Bureau of Labor Statistics' Survey of Occupational Injuries and Illnesses (SOII) data were linked to Washington workers' compensation claims to identify injury and claim characteristics associated with unreported cases. Workers' compensation administrative date data were used to characterize timing of disability and SOII case eligibility. RESULTS: Based on claim date data, one in five lost time claims with an injury date in the survey year were likely ineligible for SOII case reporting during the survey year. Among SOII-eligible claims, those involving sprains or strains, employer protests, and those not eligible for work disability payments until months after the initial injury were least likely to be reported in SOII. CONCLUSIONS: SOII case capture is limited both by its cross sectional survey design and employer underreporting. Am. J. Ind. Med. 60:264-275, 2017. © 2017 Wiley Periodicals, Inc.

Employer reasons for failing to report eligible workers' compensation claims in the BLS survey of occupational injuries and illnesses.

BACKGROUND: Little research has been done to identify reasons employers fail to report some injuries and illnesses in the Bureau of Labor Statistics Survey of Occupational Injuries and Illnesses (SOII). METHODS: We interviewed the 2012 Washington SOII respondents from establishments that had failed to report one or more eligible workers' compensation claims in the SOII about their reasons for not reporting specific claims. Qualitative content analysis methods were used to identify themes and patterns in the responses. RESULTS: Non-compliance with OSHA recordkeeping or SOII reporting instructions and data entry errors led to unreported claims. Some employers refused to include claims because they did not consider the injury to be work-related, despite workers' compensation eligibility. Participant responses brought the SOII eligibility of some claims into question. CONCLUSION: Systematic and non-systematic errors lead to SOII underreporting. Insufficient recordkeeping systems and limited knowledge of reporting requirements are barriers to accurate workplace injury records.

Unreported workers' compensation claims to the BLS Survey of Occupational Injuries and Illnesses: Establishment factors.

BACKGROUND: Studies suggest employers underreport injuries to the Bureau of Labor Statistics Survey of Occupational Injuries and Illnesses (SOII); less is known about reporting differences by establishment characteristics. METHODS: We linked SOII data to Washington State workers' compensation claims data, using unemployment insurance data to improve linking accuracy. We used multivariable regression models to estimate incidence ratios (IR) of unreported workers' compensation claims for establishment characteristics. RESULTS: An estimated 70% of workers' compensation claims were reported in SOII. Claims among state and local government establishments were most likely to be reported. Compared to large manufacturing establishments, unreported claims were most common among small educational services establishments (IR = 2.47, 95%CI: 1.52-4.01) and large construction establishments (IR = 2.05, 95%CI: 1.77-2.37). CONCLUSIONS: Underreporting of workers' compensation claims to SOII varies by establishment characteristics, obscuring true differences in work injury incidence. Findings may differ from previous research due to differences in study methods.

Exploring the relationship between employer recordkeeping and underreporting in the BLS Survey of Occupational Injuries and Illnesses.

BACKGROUND: Little empirical data exist to identify the reasons for underreporting in the US Bureau of Labor Statistics (BLS) non-fatal occupational injury and illness data. METHODS: We interviewed occupational injury and illness record keepers from Washington State establishments that participated in the 2008 BLS Survey of Occupational Injuries and Illnesses (SOII). Qualitative and quantitative methods were used to explore recordkeeping and business practices that may explain SOII's incomplete case capture compared with WC claims data. RESULTS: Most participants (90%) did not comply with OSHA recordkeeping regulations. Other factors including using workplace injury data to evaluate supervisors' or SOII respondent's job performance, recording injuries for a worksite that operates multiple shifts, and failing to follow SOII instructions were more common among establishments with unreported WC claims. CONCLUSION: Business practices that incentivize low injury rates, disorganized recordkeeping, and limited communication between BLS and survey respondents are barriers to accurate employer reports of work-related injuries and illnesses.

Injury classification agreement in linked Bureau of Labor Statistics and Workers' Compensation data.

BACKGROUND: Estimates of select occupational injuries and illnesses often differ across data sources. We explored agreement in injury classifications and the impact of differences on case estimates among records reported to multiple data sources. METHODS: We linked cases reported in the Bureau of Labor Statistics (BLS) annual Survey of Occupational Injuries and Illnesses (SOII) to Washington State workers' compensation (WC) claims and evaluated agreement in injury characteristics coded in each data source according to the same occupational injury and illness classification system. RESULTS: Agreement between data sources was greatest for body part and lowest for event or exposure. Agreement on nature of injury varied by condition. WC-assigned injury codes estimated 94% more amputations than SOII-assigned codes while SOII-assigned codes estimated 34% more work-related MSD cases. CONCLUSIONS: Accounting for classification differences may improve case ascertainment within individual data sources and help align injury and illness estimates derived from different data sources.

Barriers to obtaining a desired postpartum tubal sterilization.

OBJECTIVE: To determine why women do not undergo postpartum sterilization despite expressing desire during antepartum care. METHODS: In a retrospective chart review, we identified all women between March 2002 and November 2003 who requested postpartum sterilization during antepartum care but did not undergo the procedure. We report the reasons why sterilizations were not performed. RESULTS: We reviewed 6,589 prenatal care and delivery records identifying 324 women meeting inclusion criteria. One hundred and four women changed their mind. Of women still desiring sterilization at discharge, the most common reasons for not undergoing the procedure were lack of valid Medicaid sterilization consent forms [n=121; 37.3%, 95% confidence interval (CI) 32.0-42.6%]; a medical condition precluding the procedure (n=47; 14.5%, 95% CI 10.7-18.3%); lack of availability of an operating room (n=2; 6.5%, 95% CI 3.8-9.2%). CONCLUSION: We found that the Medicaid consent process, medical conditions and insufficient operating room space prevented women from having the desired surgery.

Failure to obtain desired postpartum sterilization: risk and predictors.

OBJECTIVE: The aim of this study was to assess the rate of and risk factors for not obtaining postpartum sterilization among women who expressed a desire for sterilization during antepartum care. METHODS: In this retrospective study, we identified a cohort of women who expressed desire for postpartum sterilization at our center between March 2002 and November 2003. We compared women who did and those who did not undergo the procedure, based on demographic, antenatal, and intrapartum factors. RESULTS: Of the 712 women who expressed desire for postpartum sterilization during antepartum care, 327 (46%) did not undergo the procedure. In multivariable analysis, women who were between the ages of 21 and 25 years (adjusted odds ratio [OR] 0.56, 95% confidence interval [CI] 0.35-0.89), were African American (OR 0.68, 95% CI 0.47-1.00), requested sterilization in the second trimester (OR 0.50, 95% CI 0.29-0.86)), and had a vaginal delivery (OR 0.21, 95% CI 0.14-0.32) rather than cesarean delivery were least likely to undergo postpartum sterilization. CONCLUSION: Despite their initial request, only 54% of women in our sample underwent sterilization. Young age, African-American race, request in the second trimester, and vaginal delivery were significantly associated with not undergoing sterilization. Our data suggest that providers should counsel all women who desire postpartum sterilization about the wide array of contraceptive methods available, with the understanding that approximately half of all women may not undergo the sterilization procedure. LEVEL OF EVIDENCE: II-2.
