ABSTRACT Factors associated with private health insurance payment rates for musculoskeletal back disorders were examined among a 15-year cohort of union carpenters. Payment patterns were contrasted with work-related back injury rates over time.
Negative binomial regression was used to assess payment rates; generalized estimated equations accounted for multiple observations per person and cost correlation within subjects.
Payment rates increased after work-related injury and with the number of injuries. Increasing private payments and deductibles (inflation-adjusted and discounted) were observed in contrast with a marked decline in reported work-related injuries.
Private insurance payments do not appear to be independent of work-related back injury. Findings suggest cost-shifting from workers' compensation to the union-provided health insurance and to the worker; they also provide a warning regarding reliance on workers' compensation statistics for surveillance of work-related disorders or disease.

    ABSTRACT: Compare rates of medical insurance claims for musculoskeletal disorders (MSD) between workers in a construction trade and a general worker population to determine if higher physical exposures in construction lead to higher rates of claims on personal medical insurance.

    ABSTRACT: BACKGROUND: Individuals who work in the construction industry are at high risk of occupational injury. Robust surveillance systems are needed to monitor the experiences of these workers over time. METHODS: We updated important surveillance data for a unique occupational cohort of union construction workers to provide information on long-term trends in their reported work-related injuries and conditions. Combining administrative data sources, we identified a dynamic cohort of union carpenters who worked in Washington State from 1989 through 2008, their hours worked by month, and their workers' compensation claims. Incidence rates of reported work-related injuries and illnesses were examined. Poisson regression was used to assess risk by categories of age, gender, time in the union, and calendar time contrasting medical only and paid lost time claims. RESULTS: Over the 20-year study period, 24,830 carpenters worked 192.4 million work hours. Work-related injuries resulting in medical care or paid lost time (PLT) from work occurred at a rate of 24.3 per 200,000 hr worked (95% CI: 23.5-25.0). Medical only claims declined 62% and PLT claims declined 77%; more substantive declines were seen for injuries resulting from being struck and falls to a lower level than from overexertion with lifting. Differences in risk based on union tenure and age diminished over time as well. CONCLUSIONS: Significant declines in rates of reported work-related injuries and illnesses were observed over the 20-year period among these union carpenters. Greater declines were observed among workers with less union tenure and for claims resulting in PLT. Am. J. Ind. Med. © 2012 Wiley Periodicals, Inc.

    ABSTRACT: This paper examines the short- and medium-term effects of the PensionDanmark Health Scheme, the largest privately administered health program for workers in Denmark, which provides prevention and early management of work-related injuries. We use a difference-in-differences approach that exploits a natural variation in the program rollout across collective agreement areas in the construction sector and over time. The results show only little evidence of an effect on the prevention of injuries requiring medical attention in the first three years after the program was introduced. Despite this, we find evidence of significant positive effects on several labor market outcomes, suggesting that the program enables some work-injured individuals to maintain their work and earnings capacity. In view of its low costs, the program appears to be cost-effective overall.
