Introduction: Workers' compensation injuries entail burdensome financial and social costs. This study's objective was to describe cost and frequency of workplace injuries in aviation manufacturing in the state of Kansas using workers' compensation data. Manufacturing incurs more workers' compensation claims in Kansas than any other industry, and aviation contributes more of those claims than any other sub sector., Method: Workers' compensation insurance and reporting are required in the state of Kansas. Data were provided by the Kansas Department of Labor (KDOL) and included all closed workers' compensation claims entailing indemnity and medical costs filed in the state from 2014 to 2022. Cost of claim data were normalized to 2022 U.S. dollars and data were analyzed as a function of percentage and claim cost by body part, type of injury, cause of injury, specific musculoskeletal disorder type, and as a function of age and gender injury rates., Results: Aviation claims entailed a median total cost of $26,941 and represented 8% of all closed claims filed in the state from 2014 to 2022. The grand total direct cost over the nine-year period was $75,404,147. Medical costs comprised 48.6% of all costs, indemnity 45.0%, and legal 6.4%. The most frequently injured body part was the hand/wrist (35.9%) followed by the shoulder (20.6%), and the most expensive body parts were related to the back. Overexertion (38.6%) was the most common cause followed by repetitive motion (22.8%). Work-related musculoskeletal disorders were the most common type accounting for 67.4% of all claims. Men and workers aged 55-64 incurred slightly higher claim rates than average. A sharp decrease in number of claims closed in 2021 coincided with production shutdowns the previous year related to the Covid-19 pandemic and design issues., Conclusions: Aviation manufacturing is a key industry in Kansas and this study is the first known to describe costs and frequencies of workplace injuries in the sector using workers' compensation data., Practical Applications: This guide to the most problematic and costly injuries in aviation manufacturing helps practitioners prioritize prevention strategies to most effectively reduce workplace injury and helps safety and health practitioners in prioritizing prevention efforts to reduce the most severe and costly aviation manufacturing injuries and illnesses. It also brings attention to some special considerations when working with safety data from 2020 to 2022 related to the Covid-19 pandemic., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 National Safety Council and Elsevier Ltd.

Work-related musculoskeletal disorders (WRMSD) pose a significant occupational health challenge in Europe. The digitization of the economy substantially reshaped the nature and organization of work. The proliferation of hybrid working, characterized by a combination of office-based and remote work, has been accelerated by the COVID-19 pandemic. This review covers hybrid forms of work, their impact on WRMSDs, and the potential implications for WRMSD compensation. Approximately 30-40% of the European workforce could potentially transition to hybrid forms of work. Hybrid work arrangements can result in prolonged static postures of the trunk, neck, and upper limbs without adequate breaks, thereby increasing the risk of neck and lower back pain. As teleworking and hybrid working become more prevalent, an increase in non-specific WRMSDs is anticipated among the working population. In many countries, claims for WRMSDs necessitate a formal diagnosis by a healthcare professional. However, cases of non-specific WRMSDs, such as cervicalgia or chronic shoulder pain, - commonly observed in sedentary workers engaged in predominantly low-intensity, prolonged static work amid visually and cognitively demanding tasks - often do not meet the criteria for compensation as occupational diseases. The compensation system and/or the criteria for compensation must be adapted to accommodate the rise of telework, necessitating evolving criteria for compensation that address both medical and risk exposure considerations.

Farm workers are exposed to high risk of heat-related illness, especially when their jobs require working outside at a fast pace during hot days. Climate change has increased the number of days with high temperatures, and thereby the amount of time that farm workers are likely exposed to extreme heat. To better understand how high heat exposure affects farm workers, this study investigates how crop workers respond to heat exposure and estimates the effects of different pay and work arrangements on workers' responses to heat exposure. We explore, specifically, whether piece-rate arrangements increase workers' effort during periods with high heat exposure compared to workers paid by hourly wages. We use observational data from detailed measurements of localized heat exposure and individual workers' effort in the field. First, these results show workers adjust their effort in response to heat exposure when the heat exposure level changes. Second, piece-rate arrangements increase workers' effort during work shifts. Third, piece-rate arrangements allow workers to modify their effort more easily during different heat exposure levels. When facing low levels of heat exposure, workers who were paid by piece-rate arrangements exert a higher effort than workers paid by hourly wages, up until WBGT is 26.6˚C. When facing high levels of heat exposure (with WBGT exceeding 29.6˚C), workers paid by piece-rate arrangements lower their effort compared to workers paid by hourly wage arrangements., Competing Interests: The authors have declared that no competing interests exist.

Purpose: To explore the best pricing benchmark for workers' compensation drugs reimbursement at retail pharmacies. Materials & methods: We used California workers' compensation system (CAWCS) total cost of pharmacy dispensed medications (2017-2019) as a proxy to estimate drug prices using alternative pricing mechanism fee schedules. Results: CAWCS paid 65.6% of the average wholesale price (AWP), 104.1% of Medi-Cal, 122.1% of the wholesale acquisition cost (WAC), 140.1% of the national average drug acquisition cost (NADAC), and 253.5% of the federal upper limit. In addition, we found the AWP-based formulas: CAWCS = AWP - 34.4%, Medi-Cal = AWP - 36.9%, WAC = AWP - 46.3%, NADAC = AWP - 53.2%, and federal upper limit = AWP - 74.1%. We found that AWP: 50% for generics and AWP - 18.2% for brands are the lowest paying formulas. The estimated median cost savings were $8.7 million (by adapting 97% of the WAC) and $9.5 million (by adapting the NADAC) across all states. Conclusion: NADAC was the best pricing benchmark for reimbursement of pharmacy dispensed drugs.

Increasing intensification in swine production has led to new and specialized technologies, but the occupational health and safety impacts are rarely quantified in the business plans for adoption. Needle-less injection has potential to increase productivity and eliminate needle stick injury in workers, but it is not clear whether these benefits offset high capital investment and potential increases in musculoskeletal loads. This economic evaluation employed probabilistic scenario analysis using injury, cost, and production data gathered from interviews with swine producers in Manitoba and Saskatchewan. After adoption of needle-less injection, rates of needle-stick injury went down with no measureable effect on upper limb musculoskeletal disorders, resulting in lower health and safety costs for needle-less injectors. Needle-less injection duration was 40% faster once workers acclimatized, but large start-up costs mean economic benefits are realized only after the first year. The incremental benefit cost ratio promoted adoption of needle-less injectors over conventional needles for the base case of a 1200 sow barn; the conventional method is beneficial for barns with 600 sows or less. Findings indicate that well-designed technologies have the potential to achieve the dual ergonomics goals of enhancing human wellbeing and system performance. We anticipate that the economic and decision models developed in this study can be applied to other new technologies in agriculture and animal production., Competing Interests: The authors have declared that no competing interests exist.

Introduction: Cardiovascular disease, and particularly myocardial infarction (MI), carries a significant economic burden, through productivity losses (indirect costs) associated with temporary absence from work, that has not yet been adequately studied in Portugal. Our objective was to quantify the indirect costs of MI in the first year after admission., Methods: Consecutive patients admitted to a single center aged <66 years who survived to discharge during a one-year period were included. Employment status on admission was assessed and for every employed patient, their monthly wage was estimated from market wage rates taken from the Ministry of Labor database according to gender and age. The duration of temporary absence from work was assessed in follow-up contacts for up to one year. Indirect costs were calculated in this sample and the results were applied to the number of MIs in Portugal during 2016 and separately to ST-elevation MI (STEMI) and non-ST-elevation acute coronary syndrome., Results: A total of 219 patients were included, of whom 66.2% were working. The mean monthly labor cost was 1802 euros. A total cost of 760 521.55 euros was obtained. At national level there were 4133 patients aged <66 years admitted with acute MI who survived to discharge. Costs were higher in STEMI patients and the total indirect cost was estimated at 10.12 million euros., Conclusions: In Portugal, the costs to society of disability-generated productivity losses exceed ten million euros in the first year after MI. Strategies to promote an earlier return to work are needed to lower these costs., (Copyright © 2020 Sociedade Portuguesa de Cardiologia. Publicado por Elsevier España, S.L.U. All rights reserved.)

Background: Given the elevated risk of tuberculosis (TB), including drug-resistant disease, experienced by health workers in South Africa (SA), effective workers' compensation for occupational TB is a legal right and an essential social benefit., Objectives: To investigate the experience of the workers' compensation system among health workers who suffered from TB while working in public service facilities in Western Cape Province, SA., Methods: In this case series with a qualitative component, 300 claims for occupational TB in health workers were sampled from the provincial health department database of claims submitted. Claim status for each case was ascertained. An attempt was made to contact each health worker for a telephonic interview consisting of both closed- and open-ended (qualitative) questions. Fifty-one interviews were completed., Results: In nearly half of the cases, there was no record of claim status on the state Compensation Fund website. Of the 51 interviewees, only one had received all the compensation benefits for their particular claim circumstances. Health workers' experience of having their cases reported for compensation purposes was marred by perception of poor communication and administration. The experience of contracting TB was further characterised by surprise, perceptions of stigma, financial burden and ongoing ill-health., Conclusions: Affected health workers' experience of the workers' compensation system was mostly negative, adding to the burden of being ill with TB. Education of management and clinicians, improvement in communication, and timeous and regular checking of claim status and of payment of applicable compensation are required at the provincial level. Dedicated facility-based occupational health units are needed, with a staff complement of knowledgeable persons trusted by their colleagues. However, the effectiveness of the system is ultimately dependent on the ability of the Compensation Fund to register and display claims timeously and administer compensation expeditiously.

While many stakeholders believe worker wages in global supply chains are too low, there is disagreement about what, if anything, can be done to raise wages. Through a two-year quasi-experiment in an operating apparel factory, we assess the effects on productivity and profits of raising worker wages with a re-designed compensation system. We show that, even within current factory margins and constraints, important wage gains (4.2-9.7%) are possible and profitable. Productivity increased 8-10%-points while turnover decreased markedly. Workers were motivated by the potential for increased wages from an accelerating group rate as well as increased engagement and sense of fair compensation. Workers focused their increased effort on reducing quality defects and tardiness, two behaviors which individual workers largely control. Additional productivity-increasing behaviors were constrained by skill, position, and conflicts arising from free riders. Advanced apparel manufacturing demands a more engaged workforce; this research provides early evidence that compensation systems can be a critical tool to meet multiple needs., Competing Interests: The authors have declared that no competing interests exist.

We aimed to assess the predictivity of the biomechanical job-exposure matrix 'MADE' using compensation data from the National Health Insurance for work-related disorders. Data were obtained from 2013 to 2015, area under curves (AUC), sensitivity, specificity and predictive values were calculated using compensation results as reference. We collected 163 128 cases data. AUC ranged from 0.64 for shoulders disorder to 0.82 for knee disorders. If two thresholds were considered, 28.7% of the sample fit under or over those. The matrix showed a fair predictivity. Such matrix cannot replace expertise but might be a tool used for improving compensation process., (© The Author(s) 2019.

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., (Copyright © 2019 Elsevier Ltd and National Safety Council.

Background: Although medically necessary in some cases, there is growing concern that compounded medications are being overprescribed, leading to questions about safety and necessity for high use and cost. Safety concerns regarding compounded medications were highlighted by the 2013 contamination of steroid injections by the New England Compounding Center, which caused serious infections and other injuries to at least 751 patients and resulted in at least 64 patient deaths. A study contributed to our understanding of compounded medication use and cost, finding in a sample of commercially insured population that the average ingredient cost for compounded medication prescriptions was $710.36, which is 130% higher than for noncompounded medication prescriptions. The literature on use and cost of compounded medications in noncommercially insured populations and related regulations, however, is sparse. The California Workers' Compensation System (CAWCS)-the largest U.S. workers' compensation system and a public health system experiencing high compounded medication costs-provided an opportunity for additional analysis of these issues. Furthermore, CAWCS data on compounded medication use and cost allow for the exploration of alternative pricing mechanisms that may control costs., Objectives: To (a) examine use, cost, and billing and reimbursement practices for compounded medications in a public health system-CAWCS- and (b) evaluate regulations and recommend an alternative pricing mechanism that could control costs in California., Methods: Descriptive statistics for use, cost, and reimbursement patterns of all compounded medication prescriptions included in CAWCS's Workers Compensation Information System claims datasets from 2011 to 2013 were determined. This study coded a unique dataset that (a) identified compounded medications at the ingredient level; (b) grouped compounded medications from ingredient level to compounded medications as a whole; and (c) categorized compounded medications into applicable Colorado pricing categories. T-tests assessed if regulation AB 378, which targets compounded medications, was associated with a difference in mean cost. The Colorado pricing scheme was applied to estimate cost and provide recommendations., Results: Despite the AB 378 requirement for compounded medications to be billed at the ingredient level for reimbursement, 15% of pharmacy-dispensed and 6% of physician-dispensed medications were not billed at the ingredient level. For pharmacy-dispensed compounded medications billed at the ingredient level, mean amount paid (SD) per ingredient was $45.40 (195.97), and for those medications billed at the single compounded medication level, mean amount paid (SD) per medication was $95.20 (326.33) over all years. For physician-dispensed medications billed at the ingredient level, mean amount paid (SD) per ingredient was $75.47 (205.51), and when billed at the single medication level was $204.83 (221.01). T-tests showed a mean increase in compounded medication mean amount paid between pre- and post-AB 378 groups of $12.27 ( P < 0.001) for pharmacy-dispensed medications and $11.34 ( P < 0.001) for physician-dispensed medications, suggesting that AB 378 did not curb compounded medication mean amount paid., Conclusions: The average cost of CAWCS pharmacy- and physician-dispensed compounded medications consistently increased. Various factors may have influenced this increase, but AB 378 did not achieve its full regulatory intent to standardize billing and reimbursement and control cost. Grouping of ingredients into compounded medications allowed for application of the Colorado pricing scheme to CAWCS claims data. Adoption of Colorado pricing would save 46% of current compounded medication cost for less complicated medications, while increasing cost for more complicated medications. The analyses recommended a revised Colorado pricing scheme, which would provide improved incentives for accurate billing and lead to savings for CAWCS., Disclosures: Funding for this study was provided by the California Workers' Compensation System. The authors had final control regarding study design, study conduct, and writing of the manuscript. The authors report no conflicts of interest.

Background: Patient/resident-handling tasks are physically demanding and associated with musculoskeletal disorders (MSDs) among nursing personnel. The routine performance of such tasks by physical therapists and occupational therapists during treatment can cause similar problems., Objective: This study characterized the magnitude of MSDs and the risk factors for MSDs in physical therapists, occupational therapists, physical therapist assistants, and occupational therapist assistants (collectively called "therapy personnel" for this study) and compared them with those of other nursing home workers, especially nursing staff., Design: This was a cross-sectional study., Methods: Workers' compensation claim (WCC) data from 1 year of experience in a long-term care company were used to compute claim rates by body region, nature, and cause of injury, and the costs per case and per full-time-equivalent employee. Data regarding musculoskeletal symptoms, use of patient/resident-lifting equipment, and perceived physical and psychological job demands were obtained from a concurrent cross-sectional survey of workers from 24 long-term care facilities., Results: About 80% of the WCCs were related to musculoskeletal incidents in nursing aides and therapy personnel. WCC costs paid per case for therapy personnel were more than twice those for nursing staff for both ergonomic and resident-handling incidents. Prevalence of low back pain in therapy personnel was the same as in nursing aides (48%) but involved more chronic, milder pain. About half of therapy personnel reported "never" or "rarely" using patient/resident-lifting equipment. Therapy personnel, nursing aides, and housekeeping/dietary/maintenance personnel reported the highest physical job demands., Limitations: Causal inference cannot be determined due to the cross-sectional nature of the survey data. Study findings are relevant only to therapy work in long-term care settings because exposures vary in other health care settings (hospitals, outpatient, and others)., Conclusions: MSD prevalence and claim costs in therapy personnel are high enough to deserve more attention. The low use of patient/resident-lifting equipment in therapy could increase the risk for MSDs. Future studies with comprehensive ergonomic analysis of therapist tasks and recommendations to reduce injuries are warranted., (© 2019 American Physical Therapy Association.)

Objective: To examine the effects of provider choice policies on workers' compensation medical and indemnity costs., Data Sources/study Setting: Pooled cross-sectional analysis of administrative claims records for workers with work-related injuries primarily in 2007-2010 across 25 states (n = 4,489,729)., Study Design: We used linear and quantile regression analyses to evaluate differences in claim costs (medical and indemnity) based on whether policies give employers or injured workers control over the choice of provider., Principal Findings: We find no difference in average medical costs by provider choice policies, although a distributional analysis indicates higher developed medical costs for the costliest back injury cases in states where workers control provider choice. The evidence for indemnity costs is similar, although the point estimates also indicate (statistically insignificantly) higher average costs when policies give workers more control of the choice of provider., Conclusions: Our nuanced evidence suggests that policymakers seeking to reduce workers' compensation costs may need to focus on the highest cost cases in states where policy gives workers more control over the choice of provider, rather than the simpler and broader issue of whether policy gives workers or employers more control., (© Health Research and Educational Trust.)

Medical care represents an important component of workers' compensation benefits with the potential to improve health and post-injury labor outcomes, but little is known about the relationship between medical care spending and the labor outcomes of injured workers. We exploit the 2003--2004 California workers' compensation reforms which reduced medical spending disproportionately for workers incurring low back injuries. We link administrative claims data to earnings records for injured workers and their uninjured coworkers. We find that workers with low back injuries experienced a 7.6 percent post-reform decline in medical care, and an 8.1 percent drop in post-injury earnings relative to other injured workers.

This study aimed to describe the epidemiological characteristics, the occupational context, and the cost of hospitalised work-related traumatic spinal injuries, across New South Wales, Australia. A record-linkage study of hospitalised cases of work-related spinal injury (ICD10-AM code U73.0 or workers compensation) was conducted. Study period 2013⁻2016. Eight hundred and twenty-four individuals sustained work-related spinal injuries; 86.2% of whom were males and had a mean age of 46.6 years. Falls led to 50% of the injuries; predominantly falls from building/structures, ladders or between levels. Falls occurred predominantly in the construction industry (78%). Transport crashes caused 31% of injuries and 24% in heavy vehicles. Half of all the transport injuries occurred 'off road'. The external cause was coded as 'non-specific work activity' in 44.5% of cases; missing in 11.5%. Acute care bed days numbered at 13,302; total cost $19,500,000. High numbers of work-related spinal injuries occurred in the construction industry; particularly falling from a height. Off-road transport-related injuries were significant and likely unaddressed by 'on-road' prevention policies. Medical record documentation was insufficient in injury mechanism and context specificity. Workers in the construction industry or those using vehicles off-road were at high risk of spinal injury, suggesting inefficient systems approaches or ineffective prevention policies. Reducing the use of non-specific external cause codes in patients' medical records would improve the measurement of policy effectiveness.

Background: Sales of medical foods (MFs) and convenience packages (CPs) are projected to exceed $2 billion in the United States, with an annual growth rate of 10%. Several studies have highlighted the rapid growth of MF use within the California Workers' Compensation System (CAWCS). To curb this growth, California implemented Assembly Bill 378 (AB 378) in 2012 to regulate physicians' incentives to dispense MFs and CPs. AB 378's regulation on only physician-dispensed MFs and CPs and not pharmacy-dispensed MFs and CPs generated a setting for evaluating the differential effect of the bill on MF and CP use and cost., Objectives: To (a) examine the use and cost of MFs and CPs in the CAWCS that are not for inborn errors of metabolism and (b) evaluate the regulatory effect of AB 378., Methods: This study adopted a quantitative approach and employed descriptive statistics and t-tests. The analyses used the most recent complete annual claims data from the Workers' Compensation Information System dataset to evaluate MF and CP claims frequencies and dollar amounts reimbursed from 2011 to 2013 and to compare the difference between physician-dispensed and pharmacy-dispensed products., Results: Of 151,107 MFs and CPs billed, 95,528 (63.2%) prescriptions were reimbursed. The reimbursed MFs and CPs accounted for approximately $19 million paid to pharmacies and physicians over 3 years. Physician-dispensed MFs, which were regulated by AB 378 in January 2012, experienced a reduction in mean amount reimbursed by $9.95 (P < 0.001)-from $195.64 to $185.68-compared with the mean amount reimbursed in 2011. Conversely, physician-dispensed CPs, as well as pharmacy-dispensed MFs and CPs, did not experience a decrease in mean amount reimbursed., Conclusions: The results indicated that AB 378 was associated with a statistically significant reduction in physician-dispensed MFs. Concomitantly, the results from t-tests showed no statistically significant difference in mean amount reimbursed for MFs and CPs to pharmacies before and after AB 378. The finding was expected and as hypothesized because AB 378 did not regulate pharmacy-dispensed MFs and CPs. Legislative measures, such as AB 378 in California, may influence rising costs and use of MFs and CPs in general. Other workers' compensation systems could adopt similar legislation to affect the behavior of physician prescribing of non-inborn errors of metabolism MFs and further test these findings., Disclosures: Funding for this study was contributed by the California Workers' Compensation System. The authors have nothing to disclose.

Background: South Africa's mineral resources have produced, and continue to produce, enormous economic wealth; yet decades of colonialism, apartheid, capital flight, and challenges in the neoliberal post-apartheid era have resulted in high rates of occupational lung disease and low rates of compensation for ex-miners and their families. Given growing advocacy and activism of current and former mine workers, initiatives were launched by the South African government in 2012 to begin to address the legacy of injustice. This study aimed to assess developments over the last 5 years in providing compensation, quantify shortfalls and explore underlying challenges., Methods: Using the database with compensable disease claims from over 200,000 miners, the medical assessment database of 400,000 health records and the employment database with 1.6 million miners, we calculated rates of claims, unpaid claims and shortfall in claim filing for each of the southern African countries with at least 25,000 miners who worked in South African mines, by disease type and gender. We also conducted interviews in Johannesburg, Eastern Cape, Lesotho and a local service unit near a mine site, supplemented by document review and auto-reflection, adopting the lens of a critical rights-based approach., Results: By the end of 2017, 111,166 miners had received compensation (of which 55,864 were for permanent lung impairment, and another 52,473 for tuberculosis), however 107,714 compensable claims remained unpaid. Many (28.4%) compensable claims are from Mozambique, Lesotho, Swaziland, Botswana and elsewhere in southern Africa, a large proportion of which have been longstanding. A myriad of diverse systemic barriers persist, especially for workers and their families outside South Africa. Calculating predicted burden of occupational lung disease compared to compensable claims paid suggests a major shortfall in filing claims in addition to the large burden of still unpaid claims., Conclusion: Despite progress made, our analysis reveals ongoing complex barriers and illustrates that the considerable underfunding of the systems required for sustained prevention and social protection (including compensation) needs urgent attention. With class action suits in the process of settlement, the globalized mining sector is now beginning to be held accountable. A critical rights-based approach underlines the importance of ongoing concerted action by all.

Background: The objectives of this study were (1) to identify age and sex trends in the disability burden of compensated work-related musculoskeletal disorders (MSDs) in Canada and Australia; and (2) to demonstrate a means of comparing workers' compensation data internationally., Methods: All non-fatal, work-related MSD claims with at least one day of compensated time-loss were extracted for workers aged 15-80 during a 10-year period (2004-2013) using workers' compensation data from five Canadian and eight Australian jurisdictions. Disability burden was calculated for both countries by sex, age group, and injury classification, using cumulative compensated time-loss payments of up to two years post-injury., Results: A total of 1.2 million MSD claims were compensated for time-loss in the Canadian and Australian jurisdictions during 2004-2013. This resulted in time-loss equivalent to 239,345 years in the Canadian jurisdictions and 321,488 years in the Australian jurisdictions. The number of time-loss years declined overall among male and female workers, but greater declines were observed for males and younger workers. The proportion of the disability burden grew among older workers (aged 55+), particularly males in the Canadian jurisdictions (Annual Percent Change [APC]: 7.2, 95% CI 6.7 to 7.7%) and females in the Australian jurisdictions (APC: 7.5, 95% CI 6.2 to 8.9%)., Conclusions: The compensated disability burden of work-related MSDs is shifting towards older workers and particularly older females in Australia and older males in Canada. Employers and workers' compensation boards should consider the specific needs of older workers to reduce injuries and time off work. Comparative research made possible through research-stakeholder partnerships offers a unique opportunity to use existing administrative data to identify long-term trends in disability burden. Future research can apply similar approaches for estimating long-term trends in occupational health.

Introduction: California's Workers' Compensation System (CAWCS) Department of Industrial Relations questioned the adequacy of the current Medi-Cal fee-schedule pricing and requested analysis of alternatives that maximize price availability and maintain budget neutrality., Objectives: To compare CAWCS pharmacy-dispensed (PD) drug prices under alternative fee schedules, and identify combinations of alternative benchmarks that have prices available for the largest percentage of PD drugs and that best reach budget neutrality., Methods: Claims transaction-level data (2011-2013) from CAWCS were used to estimate total annual PD pharmaceutical payments. Medi-Cal pricing data was from the Workman's Compensation Insurance System (WCIS). Average Wholesale Prices (AWP), Wholesale Acquisition Costs (WAC), Direct Prices (DP), Federal Upper Limit (FUL) prices, and National Average Drug Acquisition Costs (NADAC) were from Medi-Span. We matched National Drug Codes (NDCs), pricing dates, and drug quantity for comparisons. We report pharmacy-dispensed (PD) claims frequency, reimbursement matching rate, and paid costs by CAWCS as the reference price against all alternative price benchmarks., Results: Of 12,529,977 CAWCS claims for pharmaceutical products 11.6% (1,462,814) were for PD drugs. Prescription drug cost for CAWCS was over $152M; $63.9M, $47.9M, and $40.6M in 2011-2013. Ninety seven percent of these CAWCS PD claims had a Medi-Cal price. Alternative mechanisms provided a price for fewer claims; NADAC 94.23%, AWP 90.94%, FUL 73.11%, WAC 66.98%, and DP 14.33%. Among CAWCS drugs with no Medi-Cal price in PD claims, AWP, WAC, NADAC, DP, and FUL provided prices for 96.7%, 63.14%, 24.82%, 20.83%, and 15.08% of claims. Overall CAWCS paid 100.52% of Medi-Cal, 60% of AWP, 97% of WAC, 309.53% of FUL, 103.83% of DP, and 136.27% of NADAC., Conclusions: CAWCS current Medi-Cal fee-schedule price list for PD drugs is more complete than all alternative fee-schedules. However, all reimbursement approaches would require combinations of pricing benchmarks. We suggest keeping primary reimbursement at 100% of Medi-Cal and for drugs without a primary Medi-Cal price calculating the maximum fee as 60% of AWP and then 97% of WAC. Alternatively, we suggest using NADAC as a primary fee-schedule followed by either 60% AWP and 97% WAC or AWP-40% for drugs with no NADAC price. Fee-schedules may not offer the best price and a formulary approach may provide more flexibility., Competing Interests: The authors have declared that no competing interests exist.

Background: Early intervention following occupational injury can improve health outcomes and reduce the duration and cost of workers' compensation claims. Financial early reporting incentives (ERIs) for employers may shorten the time between injury and access to compensation benefits and services. We examined ERI effect on time spent in the claim lodgement process in two Australian states: South Australia (SA), which introduced them in January 2009, and Tasmania (TAS), which introduced them in July 2010., Methods: Using administrative records of 1.47 million claims lodged between July 2006 and June 2012, we conducted an interrupted time series study of ERI impact on monthly median days in the claim lodgement process. Time periods included claim reporting, insurer decision, and total time. The 18-month gap in implementation between the states allowed for a multiple baseline design. In SA, we analysed periods within claim reporting: worker and employer reporting times (similar data were not available in TAS). To account for external threats to validity, we examined impact in reference to a comparator of other Australian workers' compensation jurisdictions., Results: Total time in the process did not immediately change, though trend significantly decreased in both jurisdictions (SA: -0.36 days per month, 95% CI -0.63 to -0.09; TAS: 0.35, -0.50 to -0.20). Claim reporting time also decreased in both (SA: -1.6 days, -2.4 to -0.8; TAS: -5.4, -7.4 to -3.3). In TAS, there was a significant increase in insurer decision time (4.6, 3.9 to 5.4) and a similar but non-significant pattern in SA. In SA, worker reporting time significantly decreased (-4.7, -5.8 to -3.5), but employer reporting time did not (-0.3, -0.8 to 0.2)., Conclusions: The results suggest that ERIs reduced claim lodgement time and, in the long-term, reduced total time in the claim lodgement process. However, only worker reporting time significantly decreased in SA, indicating that ERIs may not have shortened the process through the intended target of employer reporting time. Lack of similar data in Tasmania limited our ability to determine whether this was a result of ERIs or another component of the legislative changes. Further, increases in insurer decision time highlight possible unintended negative effects.

Family members, mostly female, can be at risk of asbestos-related disease as a result of the transfer of asbestos from the workplace to the home on the hair, boots and clothes of the worker. It is argued that in these cases the home should be recognised as an extension of the workplace and that the employer has a duty of care to contain and control the asbestos. Given these circumstances, the family member with the disease should be entitled to cover under the Accidence Compensation Legislation., Competing Interests: Nil.

Objectives: Few studies examine the influence of early predictors of work absence beyond 12 months following injury or the time-dependent relative importance of these factors. This study aimed to identify the most important sociodemographic, occupational, health, lifestyle and injury predictors of work absence at 12 and 24 months following injury and to examine changes in the relative importance of these over time., Design: Prospective cohort study., Setting: The Prospective Outcomes of Injury Study, New Zealand., Participants: 2626 injured New Zealand workers aged 18-64 years were identified from the Prospective Outcomes of Injury Study recruited form New Zealand's monopoly injury compensation provider injury claims register: 2092 completed the 12-month interview (80% follow-up) and 2082 completed the 24-month interview (79% follow-up)., Primary and Secondary Outcomes Measures: The primary outcomes of interest was absence from work at the time of the 12-month and 24-month follow-up interviews., Results: Using modified Poisson regression to estimate relative risks, important groups of workers were identified at increased risk of work absence at both 12 and 24 months: males, low-income workers, trade/manual workers, temporary employees, those reporting two or more comorbidities and those experiencing a work-related injury. Important factors unique to predicting work absence at 12 months included financial insecurity, fixed-term employment and long weekly hours worked; unique factors at 24 months included job dissatisfaction, long weekly days worked, a prior injury and sustaining an injury that was perceived to be a threat to life., Conclusions: Important early predictors of work absence at 12 or 24 months following injury are multidimensional and have a time dependent pattern. A consistent set of predictors was, however, present at both time periods that are prime for early intervention. Understanding the multidimensional, time-dependent patterns of early predictors of long-term disability is important to optimally target timely interventions to prevent long-term work disability., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Introduction: Insurance loss prevention (LP) representatives have access and contact with businesses and employees to provide targeted safety and health resources. Construction firms, especially those smaller in size, are a high-risk population. This research evaluated the association between LP rep contact and risk for lost-time injuries in construction policyholders., Methods: Workers' compensation data were utilized to track LP rep contact with policyholders and incidence of lost-time injury over time. Survival analysis with repeated events modeling calculated hazard ratios (HR) and 95% confidence intervals (CI)., Results: Compared no LP contact, one contact was associated with a 27% reduction of risk (HR=0.73, CI=0.65-0.82), two with a 41% (HR=0.59, CI=0.51-0.68), and three or more contacts with a 28% reduction of risk (HR=0.72, CI=0.65-0.81)., Conclusions: LP reps appear to be a valuable partner in efforts to reduce injury burden. Their presence or contact with policyholders is consistent with reduction in overall incidence of lost-time injuries., Practical Applications: Reduction in lost-time injuries, resulting in reduced workers' compensation costs for policyholders and insurance companies, builds a business-case for safety and injury prevention. LP reps are often a low or no-cost benefit for insurance policyholders and may be an important injury prevention resource for small firms and/or those with lack of safety resources and staff., (Copyright © 2017 The Authors.

Introduction: We analyzed workers' compensation (WC) data to identify characteristics related to workers' compensation claim outcomes among janitorial service workers in Washington State., Method: We analyzed WC data from the Washington State Department of Labor & Industries (L&I) State Fund (SF) from January 1, 2003 through December 31, 2013, for janitorial service workers employed in the National Occupational Research Agenda (NORA) Services Sector. We constructed multivariable models to identify factors associated with higher medical costs and increased time lost from work., Results: There were 2,390 janitorial service compensable claims available for analysis. There were significant differences in injury type and other factors by gender, age, and language preference. Linguistic minority status was associated with longer time loss and higher median medical costs. Women were estimated to account for 35% of janitorial service workers but made up 55% of the compensable claims in this study., Conclusions: Janitorial service workers comprise a large vulnerable occupational group in the U.S. workforce. Identifying differences by injury type and potential inequitable outcomes by gender and language is important to ensuring equal treatment in the workers' compensation process., Practical Applications: There were significant differences in injury and individual characteristics between men and women in this study. Women had twice the estimated rate of injury to men, and were more likely to require Spanish language materials. Improving communication for training and knowledge about the workers' compensation system appear to be high priorities in this population of injured janitorial service workers., (Copyright © 2017 Elsevier Ltd and National Safety Council.

Objective: To describe characteristics of industrial injury hospitalizations, and to test the hypothesis that industrial injuries were increasingly billed to non-workers' compensation (WC) payers over time., Data Sources: Hospitalization data for 1998-2009 from State Inpatient Databases, Healthcare Cost and Utilization Project, and Agency for Healthcare Research and Quality., Study Design: Retrospective secondary analyses described the distribution of payer, age, gender, race/ethnicity, and injury severity for injuries identified using industrial place of occurrence codes. Logistic regression models estimated trends in expected payer., Principal Findings: There was a significant increase over time in the odds of an industrial injury not being billed to WC in California and Colorado, but a significant decrease in New York. These states had markedly different WC policy histories. Industrial injuries among older workers were more often billed to a non-WC payer, primarily Medicare., Conclusions: Findings suggest potentially dramatic cost shifting from WC to Medicare. This study adds to limited, but mounting evidence that, in at least some states, the burden on non-WC payers to cover health care for industrial injuries is growing, even while WC-related employer costs are decreasing-an area that warrants further research., (© Health Research and Educational Trust.)

Background: One explanation for why older age is associated with greater duration of wage replacement following a work-related injury may be that older workers sustain more severe injuries and different types of injury compared with their younger counterparts., Aims: To examine the role of injury-related characteristics in explaining the impact of age on wage replacement duration, and whether the relationship between age and wage replacement duration is consistent across injury types and levels of severity., Methods: A secondary analysis of workers' compensation claims in the Australian state of Victoria. In Victoria, only injuries which have accumulated >10 days of wage replacement, or have health care expenditures above a financial threshold, are eligible for compensation. Nested regression models were used to examine the relative contribution of injury-related characteristics to age differences in wage replacement duration., Results: Older age was associated with greater days of wage replacement among men and women, even after adjusting for injury characteristics. Adjustment for differences in injury types and compensation reporting practices resulted in moderate attenuation of the age-duration relationship among men and small attenuation among women. The age-duration relationship was consistent across injury types/severity., Conclusions: The relationship between older age and greater duration of wage replacement is ubiquitous across injuries of different types and severity. Future research is required to understand better why older age is consistently associated with worse compensation outcomes following work-related injury., (© The Author 2016.

Background: Permanent occupational disability is one of the most severe consequences of diabetes that impedes the performance of usual working activities among economically active individuals. Survival rates and worker compensation expenses have not previously been examined among Mexican workers. We aimed to describe the worker compensation expenses derived from pension payments and also to examine the survival rates and characteristics associated with all-cause mortality, in a cohort of 34,014 Mexican workers with permanent occupational disability caused by diabetes during the years 2000-2013 at the Mexican Institute of Social Security., Methods: A cross-sectional analysis study was conducted using national administrative records data from the entire country, regarding permanent occupational disability medical certification, pension payment and vital status. Survival rates were estimated using the Kaplan-Meier method. Multivariate Cox proportional hazard model was used to estimate adjusted hazard ratios (HR) and 95 % confidence intervals (95 % CI) in order to assess the cohort characteristics and all-cause mortality risk. Total expenses derived from pension payments for the period were accounted for in U.S. dollars (USD, 2013)., Results: There were 12,917 deaths in 142,725.1 person-years. Median survival time was 7.26 years. After multivariate adjusted analysis, males (HR, 1.39; 95 % CI, 1.29-1.50), agricultural, forestry, and fishery workers (HR, 1.41; 95 % CI, 1.15-1.73) and renal complications (HR, 3.49; 95 % CI, 3.18-3.83) had the highest association with all-cause mortality. The all-period expenses derived from pension payments amounted to $777.78 million USD (2013), and showed a sustained increment: from $58.28 million USD in 2000 to $111.62 million USD in 2013 (percentage increase of 91.5 %)., Conclusions: Mexican workers with permanent occupational disability caused by diabetes had a median survival of 7.26 years, and those with renal complications showed the lowest survival in the cohort. Expenses derived from pension payments amounted to $ 777 million USD and showed an important increase from 2000 to 2013.

Introduction: Although occupational injuries are among the leading causes of death and disability around the world, the burden due to occupational injuries has historically been under-recognized, obscuring the need to address a major public health problem., Methods: We established the Liberty Mutual Workplace Safety Index (LMWSI) to provide a reliable annual metric of the leading causes of the most serious workplace injuries in the United States based on direct workers compensation (WC) costs., Results: More than $600 billion in direct WC costs were spent on the most disabling compensable non-fatal injuries and illnesses in the United States from 1998 to 2010. The burden in 2010 remained similar to the burden in 1998 in real terms. The categories of overexertion ($13.6B, 2010) and fall on same level ($8.6B, 2010) were consistently ranked 1st and 2nd., Practical Application: The LMWSI was created to establish the relative burdens of events leading to work-related injury so they could be better recognized and prioritized. Such a ranking might be used to develop research goals and interventions to reduce the burden of workplace injury in the United States., (Copyright © 2015 The Authors. Published by Elsevier Ltd..

Background: Occupational health and safety (OHS) information is often complex, diverse and unstructured and suffers from a lack of integration which usually precludes any systemic insight of the situation., Aims: To analyse to what extent the use of geographical information systems (GISs) can help to integrate, analyse and present OHS data in a comprehensive and communicable way relevant for surveillance purposes., Methods: We first developed a 'macro-approach' (from national to local level), mapping data related to economic activity (denominator of active workers displayed by activity sectors), as well as work-related ill-health (numerators of workers suffering from work-related ill-health). The latter data are composed of compensated occupational diseases on the one hand and work-related diseases investigated by specialized clinics on the other hand. Then, a 'micro-approach' was worked out, integrating at a plant level, using computer-aided drawing, occupational risks data and OHS surveillance data (e.g. use of medication and sickness absence data)., Results: At the macro-level, microelectronics companies and workers were mapped at different scales. For the first time, we were able to compare, up to the enterprise level, complementary data showing different pictures of work-related ill-health, allowing a better understanding of OH issues in this sector. At the micro-level, new information arose from the integration of risk assessment data and medical data., Conclusions: This work illustrates to what extent GIS is a promising tool in the OHS field, and discusses related challenges (technical, ethical, biases and interpretation) and research perspectives., (© The Author 2015.

Objective: To assess the association between early reimbursement for physiotherapy, chiropractic and opioid prescriptions for acute low back pain (LBP) with disability claim duration., Design: Observational cohort study., Setting and Participants: From a random sample of 6665 claims for acute, uncomplicated LBP approved by the Ontario Workplace Safety and Insurance Board (WSIB) in 2005, we analysed 1442 who remained on full benefits at 4 weeks after claim approval., Primary Outcome Measure: Our primary outcome was WSIB claim duration., Results: We had complete data for all but 3 variables, which had <15% missing data, and we included missing data as a category for these factors. Our time-to-event analysis was adjusted for demographic, workplace and treatment factors, but not injury severity, although we attempted to include a sample with very similar, less-severe injuries. Regarding significant factors and treatment variables in our adjusted analysis, older age (eg, HR for age ≥ 55 vs <25=0.52; 99% CI 0.36 to 0.74) and WSIB reimbursement for opioid prescription in the first 4 weeks of a claim (HR=0.68; 99% CI 0.53 to 0.88) were associated with longer claim duration. Higher predisability income was associated with longer claim duration, but only among persistent claims (eg, HR for active claims at 1 year with a predisability income >$920 vs ≤$480/week=0.34; 99% CI 0.17 to 0.68). Missing data for union membership (HR=1.27; 99% CI 1.01 to 1.59), and working for an employer with a return-to-work programme were associated with fewer days on claim (HR=1.78; 99% CI 1.45 to 2.18). Neither reimbursement for physiotherapy (HR=1.01; 99% CI 0.86 to 1.19) nor chiropractic care (HR for active claims at 60 days=1.15; 99% CI 0.94 to 1.41) within the first 4 weeks was associated with claim duration. Our meta-analysis of 3 studies (n=51,069 workers) confirmed a strong association between early opioid use and prolonged claim duration (HR=0.57, 95% CI 0.48 to 0.69; low certainty evidence)., Conclusions: Our analysis found that early WSIB reimbursement for physiotherapy or chiropractic care, in claimants fully off work for more than 4 weeks, was not associated with claim duration, and that early reimbursement for opioids predicted prolonged claim duration. Well-designed randomised controlled trials are needed to verify our findings and establish causality between these variables and claim duration., (Published by the BMJ Publishing Group Limited.

An insurance allocation may help a hospital or health system achieve the following goals for its professional liability and workers' compensation self-insurance or large-deductible programs: Loss-control incentive. Stability. Equity. Comprehension. Ease of administration.

Background: Older workers often take longer to recover and experience more missed workdays after work-related injuries, but it is unclear why or how best to intervene. Knowing the characteristics of older injured workers may help in developing interventions to reduce the likelihood of work disability., Aims: To describe and compare several characteristics between younger and middle-aged working adults (25-54 years), adults nearing retirement (55-64 years) and adults past typical retirement (≥65 years), who sustained work-related musculoskeletal injuries., Methods: In this cross-sectional study, Alberta workers' compensation claimants with subacute and chronic work-related musculoskeletal injuries were studied. A wide range of demographic, employment, injury and clinical characteristics were investigated. Descriptive statistics were computed and compared between the age groups., Results: Among 8003 claimants, adults 65 years or older, compared to those 25-54 and 55-64 years, had lower education (16 versus 10 and 12%, P < 0.001) and were more likely to work in trades, transport and related occupations (50 versus 46 and 44%, P < 0.001), to have less offers of modified work (57 versus 39 and 42%, P < 0.001), more fractures (18 versus 14 and 11%, P < 0.001) and no further rehabilitation recommended after assessment (28 versus 18 and 20%, P < 0.01)., Conclusions: Injured workers past typical retirement age appeared to be a disadvantaged group with significant challenges from a vocational rehabilitation perspective. They were less likely to have modified work options available or be offered rehabilitation, despite having more severe injuries., (© The Author 2015.

This final rule implements provisions of the Strengthening Medicare and Repaying Taxpayers Act of 2012 (SMART Act) which require us to provide a right of appeal and an appeal process for liability insurance (including self-insurance), no-fault insurance, and workers' compensation laws or plans when Medicare pursues a Medicare Secondary Payer (MSP) recovery claim directly from the liability insurance (including self-insurance), no-fault insurance, or workers' compensation law or plan.

Background: With expected changes in age demographics many industry sectors may see their workforce significantly increase in age. The impact of claims and costs associated with musculoskeletal disorders in these industries may also change accordingly., Aims: To determine the age-related trends in musculoskeletal disorders, including claims and costs, in different industrial sectors in the state of Ohio, USA., Methods: Worker's compensation claims for musculoskeletal disorders in the state of Ohio between 1999 and 2004 were analysed in respect of age, industry sector, body region, and impact on cost and medical care (percentage of claims associated with surgery and number of procedures costing in excess of US$600)., Results: More than 570000 claims were analysed. Patterns of cost and disability among the majority of body regions demonstrated an increasing trend until 55 years of age, decreasing in older age groups. However, many industries demonstrated a continued increasing trend in costs with age. Shoulder and lumbar spine disorders showed unique industry-specific trends for older age groups as compared to the bell-shaped relationships for other body regions., Conclusions: Ageing appeared to have a role in the frequency and costs of musculoskeletal disorder claims in this study. However, industry-specific trends in the data suggest that job-specific risk factors may also play a role. The impact of age alone on the cost of musculoskeletal disorders cannot be determined because age is confounded by numerous lifestyle and work-related factors not identifiable in this study., (© The Author 2014.

This study aims to investigate the impact of heatwaves on worker's health and safety; to identify workers at higher risk of prevalent illnesses and injuries due to heatwaves; and to provide evidence for policy-makers and service providers. South Australian workers' compensation claims data for 2001-2010 were transformed into time series format, merged with meteorological data and analysed using generalized estimating equation (GEE) models. For total injury claims there was no significant difference detected between heatwave and non-heatwave periods. However, for outdoor industries, daily claims increased significantly by 6.2% during heatwaves. Over-represented in hot weather were male labourers and tradespersons aged ≥ 55 years, and those employed in 'agriculture, forestry and fishing' and 'electricity, gas and water'. Occupational burns, wounds, lacerations, and amputations as well as heat illnesses were significantly associated with heatwaves. Similarly, moving objects, contact with chemicals, and injuries related to environmental factors increased significantly during heatwaves, especially among middle-aged and older male workers. With the predicted increase of extremely hot weather, there is a need for relevant adaptation and prevention measures at both practice and policy levels for vulnerable work groups., (Copyright © 2014 Elsevier Inc.

The purpose of this study was to discuss the history of, and concerns regarding, the newly amended criteria of occupational cerebrovascular or cardiovascular diseases (CCVDs). Since the early 1990s, CCVDs have been the second most common occupational disease, despite fluctuations in their criteria. The first issue was the deletion of cerebral hemorrhage on duty as a recognized occupational disease in 2008. The second issue was the obscurity regarding definitions of an acute stressful event (within 24 hr before disease occurrence), short-term overwork (within 1 week), and chronic overwork (for 3 or more months). In this amendment, chronic overwork was defined as work exceeding 60 hr per week. If the average number of weekly working hours does not exceed 60 hr, night work, physical or psychological workload, or other risk factors should be considered for the recognition of occupational CCVDs. However, these newly amended criteria still have a few limitations, considering that there is research evidence for the occurrence of disease in those working fewer than 60 hr per week, and other risk factors, particularly night work, are underestimated in these criteria. Thus, we suggest that these concerns be actively considered during future amendment and approval processes.

The range of diseases covered by workers' compensation is constantly expanding. However, new regulations are required for the recognition of occupational diseases (ODs) because OD types evolve with changes in industrial structures and working conditions. OD criteria are usually based on medical relevance, but they vary depending on the social security system and laws of each country. In addition, the proposed range and extent of work-relatedness vary depending on the socio-economic conditions of each country. The Labor Standards Act (LSA) and the Industrial Accident Compensation Insurance Act (IACIA) of Korea employ lists based on their requirements without listing causes and diseases separately. Despite a considerable reshuffle in 2003, the basic framework has been maintained for 50 yr, and many cases do not fit into the international disease classification system. Since July 1, 2013, Korea has expanded the range of occupational accidents to include occupational cancers and has implemented revised LSA and IACIA enforcement decrees. There have been improvements to OD recognition standards with the inclusion of additional or modified criteria, a revised and improved classification scheme for risk factors and ODs, and so on.

In the Workers' Compensation Insurance (WCI) system in Korea, occupational diseases (ODs) are approved through deliberation meetings of the Committee on Occupational Disease Judgment (CODJ) after disease investigations when workers or medical institutions requested the Korea Workers' Compensation and Welfare Service (COMWEL) for medical care benefits. Insufficient data presented by employers or workers or lack of objective evidence may increase the possibility of disapproval. The expertise of accident investigation staff members should be reinforced and employers' and related institutions' obligations to cooperate and submit data should be specified under the law. The deliberation meetings of the CODJ are held separately for musculoskeletal, cerebro-cardiovascular, and medical diseases, and the judgments of ODs are made by the chairperson of COMWEL and six committee members by majority vote by issue. To reinforce the expertise of the members of the CODJ, periodic education and a system to accredit the committee members after appropriate education should be introduced. To fairly and quickly compensate for diseases that occur in workers, the criteria for the recognition of occupational diseases should be continuously amended and the systems for disease investigations and judgments should be continuously improved.

The Industrial Accident Compensation Insurance Act (IACIA) regulates the workers' compensation insurance system and the standards for the recognition of occupational diseases (ODs). Since its establishment in 1994, the IACIA has been amended several times. Before 2008, the approval of compensation for work-related musculoskeletal diseases (WMSDs) was decided based on the recommendation of consultants of the Korea Workers' Compensation and Welfare Service (COMWEL). The IACIA was amended in 2008, and since then, the approval of compensation for occupational injuries has been decided based on the recommendation of COMWEL consultants, whereas the approval of compensation for ODs was decided based on the judgment of Committee on Occupational Diseases Judgment (CODJ) which was established in 2008. According to the 2013 amendment to the IACIA, degenerative musculoskeletal diseases among workers engaged in musculoskeletal-burdening work should be considered compensable ODs. Despite some commendable changes to the workers' compensation insurance system, other significant issues persist. To resolve these issues, related organizations including the associations of orthopedic surgery, neurosurgery, and occupational and environmental medicine; Ministry of Employment and Labor; and COMWEL need to work cooperatively.

Some types of workers such as farmers and soldiers are at a higher risk of work-related injury and illness than workers from other occupations. Despite this fact, they are not covered under the Industrial Safety Health (ISH) Act or the Industrial Accident Compensation Insurance (IACI) Act. The Safety Aid System for Farmers (SASF) is a voluntary insurance scheme, and it is the only public compensation plan for self-employed farmers. Fifty percent of SASF premiums are subsidized by the Korean government. Soldiers are compensated by the Veterans' Pension (VP) Act. The approval standard of and procedure for the VP Act are provided in the Decree of VP Act, and the Council for VP Benefits determines work-relatedness in the claimed cases. Meanwhile, SASF applies the insurance clause automatically without any expert advice or additional procedures. Furthermore, compared with IACI, these programs pay fewer benefits to workers. Thus, a stronger institutional strategy is needed to maintain a safe work environment, to protect workers' health in unavoidably hazardous environments, and to compensate for work-related injuries and diseases.

Occupational diseases may be defined only medically or scientifically, and even then, their definition is not simple. However, compensable occupational diseases involve the additional layer of legal systems and social welfare policies as well. Their multifaceted nature makes determining the work-relatedness of these diseases more complex. Korea has established standards for the recognition of occupational diseases in Schedule 5 of the Enforcement Decree of the Labor Standards Act, and specific criteria for the recognition of occupational diseases are listed in Schedule 3 of the Enforcement Decree of the Industrial Accident Compensation Insurance Act. The new list of compensable occupational diseases comprises 13 articles as an open-ended system. The newly added articles pertain to lymphohematopoietic (Article 5) and infectious diseases (Article 9), as well as diseases of other target organs. Furthermore, the article on liver diseases (Article 8) has been partially revised. The new act has been changed to clarify the meaning as it has been presented in recent research. It is necessary to achieve agreement among concerned parties, including experts from the legal, medical, and social domains to resolve the issues of work-relatedness, causation, notion of aggravation, and so on for preparing a list and a process that are more reasonable.

Standards for the recognition of occupational diseases (ODs) in Korea were established in 1954 and have been amended several times. In 2013, there was a significant change in these standards. On the basis of scientific evidence and causality, the International Labour Organization list, European Commission schedule, and compensated cases in Korea were reviewed to revise the previous standards for the recognition of ODs in Korea. A disease-based approach using the International Classification of Diseases (10th version) was added on the previous standards, which were agent-specific approaches. The amended compensable occupational neurological disorders and occupational mental disorders (OMDs) in Korea are acute and chronic central nervous system (CNS) disorders, toxic neuropathy, peripheral neuropathy, manganese-related disorders, and post-traumatic stress disorder. Several agents including trichloroethylene (TCE), benzene, vinyl chloride, organotin, methyl bromide, and carbon monoxide (CO) were newly included as acute CNS disorders. TCE, lead, and mercury were newly included as chronic CNS disorders. Mercury, TCE, methyl n-butyl ketone, acrylamide, and arsenic were newly included in peripheral neuropathy. Post-traumatic stress disorders were newly included as the first OMD. This amendment makes the standard more comprehensive and practical. However, this amendment does not perfectly reflect the recent scientific progress and social concerns. Ongoing effort, research, and expert consensus are needed to improve the standard.

The respiratory system is one of the most important body systems particularly from the viewpoint of occupational medicine because it is the major route of occupational exposure. In 2013, there were significant changes in the specific criteria for the recognition of occupational diseases, which were established by the Enforcement Decree of the Industrial Accident Compensation Insurance Act (IACIA). In this article, the authors deal with the former criteria, implications of the revision, and changes in the specific criteria in Korea by focusing on the 2013 amendment to the IACIA. Before the 2013 amendment to the IACIA, occupational respiratory disease was not a category because the previous criteria were based on specific hazardous agents and their health effects. Workers as well as clinicians were not familiar with the agent-based criteria. To improve these criteria, a system-based structure was added. Through these changes, in the current criteria, 33 types of agents and 11 types of respiratory diseases are listed under diseases of the respiratory system. In the current criteria, there are no concrete guidelines for evaluating work-relatedness, such as estimating the exposure level, latent period, and detailed examination methods. The results of further studies can support the formulation of detailed criteria.

The Korean list of occupational skin diseases was amended in July 2013. The past list was constructed according to the causative agent and the target organ, and the items of that list had not been reviewed for a long period. The revised list was reconstructed to include diseases classified by the International Classification of Diseases (10th version). Therefore, the items of compensable occupational skin diseases in the amended list in Korea comprise contact dermatitis; chemical burns; Stevens-Johnson syndrome; tar-related skin diseases; infectious skin diseases; skin injury-induced cellulitis; and skin conditions resulting from physical factors such as heat, cold, sun exposure, and ionized radiation. This list will be more practical and convenient for physicians and workers because it follows a disease-based approach. The revised list is in accordance with the International Labor Organization list and is refined according to Korean worker's compensation and the actual occurrence of occupational skin diseases. However, this revised list does not perfectly reflect the actual status of skin diseases because of the few cases of occupational skin diseases, incomplete statistics of skin diseases, and insufficient scientific evidence. Thus, the list of occupational diseases should be modified periodically on the basis of recent evidence and statistics.

The context of specific criteria for the recognition of occupational diseases (ODs) due to physical agents in the Enforcement Decree of the Industrial Accident Compensation Insurance Act (ED-IACIA) and the Labor Standard Act (LSA) does not describe definite disease along with the agents but listed symptoms or obscure clinical conditions. Moreover, the needs for an amendment of these Acts have recently attracted renewed interest. To establish agreed criteria for compensable ODs due to physical agents, we reviewed the criteria for recognizing ODs on the basis of International Labor Organization (ILO) documents and European Union (EU) guideline. After providing a brief review of the history of OD outbreaks due to physical exposure in South Korea and the responses to them, we describe the basis for the recent amendments to the IACI Act and LSA and assess their appropriateness. On the basis of these findings, this study could be helpful for determining and compensating process of ODs. However, further work is required to ascertain the scientific relationship between diseases caused by physical agents and the exposure criteria.

The legal scope and criteria for occupational cancer in Korea was out of date. The aim of this study was to review the current criteria for occupational cancer and amend the existent criteria on the basis of recent scientific evidence. The scientific evidence and the legal list of occupational cancer were analyzed to identify the causes of occupational cancer on a global scale. The relationship between compensated occupational cancer cases and carcinogen exposure in Korea was examined. The factors associated with specific causes and target cancers were determined to produce additional criteria. Five-hundred and nineteen cases of 2,468 were awarded compensation for occupational cancer including lung, malignant mesothelioma, lymphohematopoietic, and liver cancers from January 2000 to October 2012. Between 1996 and 2005, benzene accounted for 84.4% of cases, and between 1999 and 2005, asbestos was associated with 62.3% of cases. Fourteen novel causative agents and 12 additional target cancers were identified and the final guidelines were amended to include 23 causative agents and 21 target cancers. This amendment of the criteria for occupational cancer represents the widest change in Korean history and is expected to improve the understanding of occupational cancer by providing an up-to-date and accurate reference guide.

Investigation into the frequency of compensation for occupational diseases (ODs) caused by hazardous chemicals revealed an important opportunity for the improvement and further development of occupational health and safety systems in Korea. In response to concerns after outbreaks of disease due to chemical exposure, specific criteria for recognition of ODs were established and included in the Enforcement Decree of the Labor Standard Act (LSA) and the Industrial Accident Compensation Insurance Act (IACIA) on June 28, 2013. However, the original versions of the LSA and IACIA contain several limitations. First, the criteria was listed inconsistently according to the symptoms or signs of acute poisoning. Second, all newly recognized hazardous chemicals and chemicals recognized as hazardous by the International Labor Organization (ILO) were not included in the LSA and IACIA. Although recent amendments have addressed these shortcomings, future amendments should strive to include all chemicals listed by the ILO and continuously add newly discovered hazardous chemicals as they are introduced into the workplace.

Many healthcare organizations use self-insurance programs to control professional liability and workers' compensation exposures, such as self-insured retention, a large deductible program, a trust fund, or a captive. The impact of the Affordable Care Act on self-insurance programs may take years to determine. Communication among all areas involved in the self-insurance program and the evaluation of different cost perspectives will be key to keeping the self-insurance program financially healthy. Empowering actuaries to create different scenarios also will help leaders stay on top of the issue.
