Occupational injuries to fisheries workers in Norway reported to insurance companies from 1991 to 1996

Fisheries work is one of the occupations at highest risk for occupational accidents in many countries. It is necessary to understand the injuries in order to prevent them. This study of occupational injury claims by fisheries workers in Norway made to insurance companies from 1991 to 1996 analysed the workers' age, time of injury, injury type, part of the body involved, injury event and cost. The highest injury incidence rates were among the younger fisheries workers and during the winter months. Bruises and fractures were the most frequent injury types, and fingers and hands were most often affected, whereas falls and accidents related to machines were the most common causes. Safety measures should be taken on board to prevent falls and machine-related injuries, and young fisheries workers should have better on-the-job training.     

The impact of shift work on the risk and severity of injuries for hospital employees: an analysis using Oregon workers' compensation data

BACKGROUND: While past research on health care workers has found that shift work can lead to negative physiological and psychological consequences, few studies have assessed the extent to which it increases the risk of specific work-related injuries, nor quantified and compared associated types, severity and costs. AIMS: This study aimed to derive and compare the rates, typologies, costs and disability time of injuries for various hospital worker occupations by day, evening and night shift. METHODS: This study used Oregon workers' compensation claim data from 1990 to 1997 to examine the differences in hospital employee claims (n = 7717) by shift and occupation. Oregon hospital employee claim data, hospital employment data from Oregon's Labor Market Information System and shift proportion estimates derived from the Current Population Survey (CPS) were used to calculate injury rate estimates. RESULTS: The injury rate for day shift per 10,000 employees was estimated to be 176 (95% CI 172-180), as compared with injury rate estimates of 324 (95% CI 311-337) for evening shift and 279 (95% CI 257-302), night shift workers. The average number of days taken off for injury disability was longer for injured night shift workers (46) than for day (38) or evening (39) shift workers. CONCLUSION: Evening and night shift hospital employees were found to be at greater risk of sustaining an occupational injury than day shift workers, with those on the night shift reporting injuries of the greatest severity as measured by disability leave. Staffing levels and task differences between shifts may also affect injury risk.     

Comparison of fatal and severe nonfatal traumatic work-related injuries in Washington state.

OBJECTIVE: To compare fatal and hospitalized nonfatal work-related traumatic injuries by occupation and cause. METHODS: Fatal and hospitalized nonfatal injuries occurring from 1991-1995 were identified from Washington State workers' compensation claims data. Nonfatal injuries were classified as severe if they had at least one of the following criteria: a brain or spinal cord injury, an Injury Severity Score of >/=16, or were hospitalized for more than 7 days. The frequency and rate of fatal and severe nonfatal injuries were then described by industrial risk class and cause. RESULTS: The study identified 335 fatal injuries and 4,405 hospitalized nonfatal injuries, of which 1,105 were classified as severe. Tree topping and pruning, carnival work, roofing, and metal siding and gutters risk classes had several severe nonfatal injuries, but few, if any, fatalities. Causes of fatal and severe nonfatal injuries were notably different for the roofing, restaurant, and orchard workers risk classes. CONCLUSIONS: The inclusion of severe hospitalized injuries in occupational injury surveillance systems will provide a broader view of high-risk occupations and profile of injury causation with which to direct occupational injury prevention efforts.     

Work-related eye injuries among union carpenters

Union administrative records were combined with workers' compensation data to identify a cohort of 12,958 active union carpenters, their person-time at risk, and their documented work-related eye injuries between 1989 and 1995 in the state of Washington. The injuries were described using ANSI codes for injury nature, type (mechanism), and source or object associated with the event. Injuries which resulted in paid lost time from work were also described based on the ICD-9 codes attached to claims for their medical treatment. Overall rates of filing compensation claims for eye injuries as well as age, gender, and union local specific rates were calculated. To identify high risk subgroups and explore incident and recurrent events, the person-time and events were stratified by age, gender, time in the union, claim status, and predominant type of work of the union local with which each carpenter was affiliated for multivariate analyses with Poisson regression. Eye injuries were responsible for 12 percent (n = 1730) of workers' compensation claims during this time period, exceeded only by back and finger injuries. Thirty-one claims resulted in paid lost time from work and these cases accounted for one-third of all costs for medical care for eye injuries. At least 10 percent of all medical costs for eye injuries and 35.5 percent of medical costs for eye injuries which resulted in paid lost time were associated with injuries sustained while hammering--a very common carpenter exposure. Claims were filed at an estimated rate of 6.1 per 200,000 hours worked. Individuals with previous compensation claims for eye injuries had rates of injury 1.6 times higher than individuals without previous eye injuries. Rates decreased significantly with age and time in the union. Eye injuries among these union carpenters were very common, but the rate of injuries severe enough to require paid time off work was quite low. These findings raise questions about factors which might influence the failure to use appropriate protection including availability and acceptability of eye protection, use by peers, and perception of risk.     

Medical costs and sources of payment for work-related injuries among Hispanic construction workers

OBJECTIVE: To assess medical costs of occupational injuries and sources of payment among Hispanic and non-Hispanic construction workers. METHODS: More than 7000 construction workers, including 1833 Hispanic workers were examined using the Medical Expenditure Panel Survey, 1996 to 2002. Univariate and multivariate analyses were conducted using SUDAAN. RESULTS: Annually, work-related injuries in construction cost $1.36 billion (2002 dollars), with 46% paid by workers' compensation. Compared with non-Hispanic workers, Hispanic workers were 53% more likely to have medical conditions resulting from work-related injuries, but 48% less likely to receive payment for medical costs from workers' compensation (P < 0.05). CONCLUSIONS: This study suggests an urgent need to reform the current workers' compensation system to reduce the burden shifted to injured workers and society. Such reforms should include easier access and more assistance for Hispanic and other immigrant workers.     

Cost of work-related injuries in insured workplaces in Lebanon

OBJECTIVE: To estimate the medical and compensation costs of work-related injuries in insured workplaces in Lebanon and to examine cost distributions by worker and injury characteristics. METHODS: A total of 3748 claims for work injuries processed in 1998 by five major insurance companies in Lebanon were reviewed. Medical costs (related to emergency room fees, physician consultations, tests, and medications) and wage and indemnity compensation costs were identified from the claims. FINDINGS: The median cost per injury was US dollars 83 (mean, US dollars 198; range, US dollars 0-16,401). The overall cost for all 3748 injuries was US dollars 742,100 (76% of this was medical costs). Extrapolated to all injuries within insured workplaces, the overall cost was US dollars 4.5 million a year; this increased to US dollars 10 million-13 million when human value cost (pain and suffering) was accounted for. Fatal injuries (three, 0.1%) and those that caused permanent disabilities (nine, 0.2%) accounted for 10.4% of the overall costs and hospitalized injuries (245, 6.5%) for 45%. Cost per injury was highest among older workers and for injuries that involved falls and vehicle incidents. Medical, but not compensation, costs were higher among female workers. CONCLUSION: The computed costs of work injuries--a fraction of the real burden of occupational injuries in Lebanon--represent a considerable economic loss. This calls for a national policy to prevent work injuries, with a focus on preventing the most serious injuries. Options for intervention and research are discussed.     

Work-related injuries in drywall installation

Administrative data sources were used to describe the work-related injuries of drywall carpenters, to calculate rates of occurrence, and to explore high risk sub-groups. Health insurance eligibility files were used to identify a cohort of active union carpenters affiliated with a union local whose predominant work involved drywall installation in the state of Washington. These files contained the hours worked by each individual for each month between January 1989 and December 1995, providing person-hours at risk as a union carpenter. The Washington Department of Labor and Industries (L&I) provided records of workers' compensation claims filed by these individuals. Over seven years 1773 drywall carpenters filed 2567 workers' compensation claims representing an overall rate of 53.3 per 200,000 hours worked. These claims were filed by 1046 different individuals, or 59.0 percent of the cohort. Claims resulting in paid lost time from work were filed at a rate of 12.5 per 200,000 hours worked (n = 609) by 445 (25.1%) different individuals. The most common mechanisms of injury involved being struck (38.3%), overexertion (28.1%), and falls (13.2%). Struck by injuries most commonly involved cuts to the upper extremity. Overexertion injuries were most commonly described as sprains or strains involving the back. Sheetrock was associated with over 40 percent of these injuries. Falls most commonly involved injuries to the knee followed by the back and multiple injuries. Struck by injuries decreased steadily with increasing age and increasing time in the union. There was a steady increase in the rate of falls with increasing age. Overexertion injuries were responsible for the greatest proportion of costs for medical care, permanent impairment, and paid lost days. The high rates of overexertion injuries among these workers is consistent with known ergonomic stresses on drywall jobs. However, these workers are also at high risk of acute traumatic injuries.     

Physical fitness, absenteeism and workers' compensation in smoking and non-smoking police officers

BACKGROUND: Employers seek to minimize business costs by creating conditions of employment. Relying on the presumably negative effects of smoking on variables such as workers' compensation claims, absenteeism and physical fitness scores, they seek a rational basis for requirements that employees refrain from smoking. No research has been found on police officer smoking rates relating to physical fitness, and the resulting economic variables of workers' compensation claims and absenteeism rates. AIMS: To compare police officer non-smoker and smoker physical fitness, absenteeism rates and workers' compensation claims. METHODS: The sample included 514 officers of a metropolitan police department. A physical fitness test was administered. Smoking status, yearly absenteeism rates and workers' compensation claims were collected. RESULTS: Male smokers were significantly older than non-smokers. An analysis of covariance controlling for sex and age indicated that smokers had significantly (P < or = 0.05) lower fitness scores in sit and reach flexibility, sit-ups endurance, bench press strength and bicycle ergometer cardiovascular endurance. When neither age nor sex was controlled in males, a similar trend continued. However, in females only the sit and reach and sit-up tests demonstrated statistically significant differences. Fat percentage, step-test scores, absenteeism rates and workers' compensation claims were not statistically different. CONCLUSION: These data do not provide a rational basis for the requirement that officers refrain from smoking when considering body fat and the economic savings of lower absenteeism rates and workers' compensation. To some extent, smoking policies can be justified by officers' physical fitness but there are age, gender and test protocol considerations.     

Occupational injury surveillance of traumatic injuries in Illinois, using the Illinois trauma registry: 1995-2003

BACKGROUND: Trauma registries continue to be underutilized for surveillance, despite providing data on the most severe injuries with a level of detail not available in national data sets or workers' compensation files. METHODS: We evaluate trends and patterns of traumatic occupational injuries from the Illinois Trauma Registry (ITR). RESULTS: Between 1995 and 2003, 44.4 of every 100,000 Illinois workers (age-adjusted) suffered work-related, nonfatal traumatic injuries. The majority of workers suffering traumatic injuries were white males younger than 55 years old. Falls were the most common cause of injury, and fracture of the extremities was the most common type of injury experienced by Illinois workers. Approximately 8% of all workers required either partial or total ambulatory assistance at time of discharge. CONCLUSION: The ITR provides detailed and complete data regarding the most severe occupational injuries. CLINICAL SIGNIFICANCE: In contrast to reports from national surveillance data sets, we do not observe a significant decline in occupational injuries between 1995 and 2003. Trauma registries should be used more frequently for surveillance programs, because they provide detailed and reliable data regarding the most severe occupational injuries not available in other data sets.     

Workers' compensation experience of Colorado agriculture workers, 2000-2004

BACKGROUND: Agriculture is among the most hazardous of occupations. The lack of information regarding agriculture injuries or fatalities has been recognized as an obstacle for effective injury prevention. Workers' compensation claims data for non-fatal injuries among agriculture and agri-business workers in the State of Colorado between the years of 2000 and 2004. METHODS: Workers' compensation claims are utilized to estimate injury claim incidence rates, determine the distributions of sources, causes, types and body locations of injuries, and estimate the costs of these injuries. RESULTS: Colorado agriculture and agri-business workers (e.g., cattle dealers, cattle or livestock raisers, dairy farmers) have high rates of injury claims, especially in sectors that involve interaction with animals or livestock. Grain milling operations had a high rate of injury claims among agri-business operations. Injuries related to animals, strains, machinery, and falls or slips were the most frequent among all occupations analyzed. CONCLUSIONS: Understanding the occurrence of injuries among Colorado agriculture and agri-business workers is critical to implementing and evaluating effective intervention programs for specific agriculture-related occupations. The development of safety interventions that address the worker-animal interface, fall protection systems, machinery usage, and overexertion prevention strategies is recommended.     

Occupational injuries among minors doing farm work in Washington State: 1986 to 1989.

BACKGROUND. There is growing evidence that many children are injured while engaged in agricultural work. However, little specific information on farm work-related injuries among minors is available, probably because employment or workers' compensation data for children are hard to obtain. METHODS. Workers' compensation data were used to evaluate occupational injuries among children in Washington State from 1986 through 1989. The frequency and severity of injuries among minors doing farm work were compared with the distributions of injuries among minors working in food service and all other occupations by year of injury, age of injury, and month and hour of injury. RESULTS. A total of 16,481 claims filed by children under age 18 were evaluated. Although farm workers accounted for only 7% of all claims, they made up 36% of claims filed by children under age 14, and 17% of claims filed by children aged 14 or 15. Injuries classified as serious accounted for 26% of farm worker claims compared with only 16% of all claims filed by children. CONCLUSIONS. Although injury rates could not be developed owing to the lack of denominator data, this study demonstrates that farm work is dangerous for young children.     

Prognostic factors of long-term disability in a workers' compensation system

OBJECTIVE: We identified predictive factors of long-term disability in new workers' compensation claims to guide secondary prevention research and target interventions for high-risk claims. METHODS: Workers with 4 or more days of work disability resulting from workplace injuries were followed for approximately 6 years in a population-based retrospective inception cohort study of 81,077 workers. RESULTS: Predictors of long-term disability included delay between injury and first medical treatment, older age, construction industry, logging occupation, longer time from medical treatment to claim filing, back injury, smaller firm size, female gender, higher unemployment rate, and having dependents. We used logistic and quantile regression to investigate predictors of disability. These models produced consistent information regarding predictors. CONCLUSION: These factors can be used to identify jobs or workers at increased risk for long-term disability that warrant prevention intervention.     

Evidence-based care for low back pain in workers eligible for compensation

BACKGROUND: Although guidelines for the management of low back pain have been promoted, few studies have assessed their effectiveness. One previous study did not include patients with workers' compensation claims. AIM: To assess the efficacy of evidence-based care for acute low back pain in patients eligible for workers' compensation. METHODS: In a prospective audit, workers in a health service who presented with acute low back pain were offered the option of usual care from their general practitioner or care provided by a staff specialist who practiced according to evidence-based guidelines. Outcomes were measured in terms of return to normal duties, time off work, recurrence of pain or persistence of pain. RESULTS: Evidence-based care was accepted by 65% of injured workers. Compared with those who elected usual care, these workers had less time off work, spent less time on modified duties and had fewer recurrences. A significantly greater proportion (70%) resumed normal duties immediately, and fewer developed chronic pain, than those managed under usual care. Three types of patients were identified: those who complied readily with evidence-based care, those who initially expressed firm beliefs about how they should be managed and those with occupational psychosocial factors. CONCLUSIONS: Evidence-based care can be successful in retaining patients at work, reducing time off work or on modified duties and reducing recurrences and chronicity. The gains are achieved by conscientiously talking to the patients, and not by any particular or special passive interventions.     

An epidemiological and risk analysis of Virginia workers' compensation burn claims 1999 to 2002: identifying and prioritizing preventive workplace interventions

OBJECTIVE: This study examines workers' compensation burn claims from Virginia to assess risk factors and costs associated with occupational burn injuries. METHODS: Virginia workers' compensation burn claims for the period of 1999 to 2002 were analyzed. Claim rates were determined by using the Bureau of Labor Statistics' Current Population Survey for the working population of Virginia. RESULTS: There were 5810 burn claims reported for the 4-year period examined, with the average burn rate estimated to be 4.3 per 10,000 workers. The total cost of claims was found to average $11,705,939 per year and $8059 per claim. There was over a sixfold increase for burn rates on weekends relative to weekdays. CONCLUSION: Burns are a common injury experienced by workers and are often severe. Assessing personnel issues affecting weekend employees may lead to valuable preventive interventions to reduce burn risk.     

Analysis of construction injury burden by type of work

BACKGROUND: To lay groundwork for identifying patterns of injury etiology, we sought to describe injury experience associated with types of work performed at construction sites by examining workers' compensation (WC) claims for the 32,081 construction workers who built Denver International Airport (DIA). METHODS: Injury rates and WC payment rates were calculated for 25 types of work based on claims and payroll data reported to DIA's owner-controlled insurance program according to National Council on Compensation Insurance job classifications. By linking DIA claims with corresponding lost-work-time (LWT) claims filed with Colorado's Workers' Compensation Division, we were also able to obtain and examine both total and median lost days for each type of work. RESULTS: Injury experience varied widely among the types of construction work. Workers building elevators and conduits and installing glass, metal, or steel were at particularly high risk of both LWT and non-LWT injury. Median days lost by injured workers was highest (202 days) for driving/trucking. Median days lost for most types of work was much greater than previously reported for construction: 40 days or more for 18 of the 25 types of work analyzed. WC payment rates reflect both number and severity of injuries and were generally not significantly different from expected losses. They were, however, significantly higher than expected for driving/trucking, metal/steel installation, inspection/analysis, and elevator construction. CONCLUSIONS: Analysis of injury data by type of work allows targeting of safety resources to high risk construction work and would be useful in prospective surveillance at large construction sites with centrally administered workers' compensation plans.     

Methodologic issues in the use of workers' compensation databases for the study of work injuries with days away from work. I. Sensitivity of case ascertainment

BACKGROUND: Case ascertainment costs vary substantially between primary and secondary data sources. This review summarizes information on the sensitivity of state administrative databases in workers' compensation systems for the ascertainment of days-away-from-work (DAFW) work injuries for use in modeling studies. METHODS: Review of the literature supplemented by data from governmental or organizational reports or produced for this report. RESULTS: Employers currently appear to provide workers' compensation insurance coverage for 98.9% of wage and salary workers. Wage and salary jobs account for approximately 90% of jobs in the United States. In industries such as manufacturing, the fraction of covered jobs is probably closer to 98%. In Minnesota, the number of DAFW cases ascertained by the Bureau of Labor Statistics' annual survey of occupational injuries and illnesses is approximately 92-97% concordant with the number of wage compensation claims for injuries producing DAFW over the period 1992-2000, once adjustments are made to permit direct comparisons of the numbers. The workers' compensation databases provide information for more than 95% of the total DAFW resulting from work injuries. Covariate estimates are unaffected by this less than 5% loss because effects appear dependent on time from injury. CONCLUSIONS: Statewide workers' compensation administrative databases can have substantial utility for epidemiologic study of work injuries with DAFW because of their size, using high sensitivity for case ascertainment as the evaluative criterion.     

Surveillance and assessment of workplace assault injuries: analysis of Rhode Island workers' compensation claims 1998-2002

OBJECTIVE: To analyze workplace assault by rate, injury severity, and trends using Rhode Island workers' compensation claim data. METHOD: A total of 6402 workers' compensation assault claims from Rhode Island for the period of 1998 through 2002 was analyzed. Data from the U.S. Department of Labor was used to derive estimates of injury rates. RESULTS: An average rate of 27.7 assaults per 10,000 workers was found and varied only marginally across years. Females filed 75% of all assault claims, though injuries to males resulted in longer periods of indemnification. The total cost of workplace assaults was 7,025,997 dollars, averaging 1097 dollars per claim, and average indemnification duration was 16.8 days per claim. While the assault rate was relatively stable, a notable decline in both cost and indemnification periods over time was discovered. CONCLUSION: The assault rate found was among the highest reported to date, demonstrating that workplace violence remains a significant threat to employee safety. While a decline in incident severity was discovered over time, many outcomes were still serious. Preventive interventions to reduce incidents of workplace assaults among groups at the highest risk should be given highest priority.
