Getting Closer to Understanding the Economic Burden of Occupational Injury and IllnessPosted on by
A recently published landmark paper by J. Paul Leigh (Milbank Quarterly 2011 89 (6):728-772 ) makes a significant contribution to understanding the economic burden of occupational illness and injury. The paper entitled “Economic Burden of Occupational Injury and Illness in the United States” shows that the annual direct and indirect costs are at least $250 billion. This amount exceeds the individual cost of cancer, coronary heart disease, stroke, and diabetes.
As Leigh notes, the cost of injury, illness, and death from these other diseases are generally easier to assess because they require a small number of primary data sources, typically 1 to 4. In contrast, estimates of the burden of occupational injury and illness are more difficult to accomplish because they rely on far more primary and secondary sources of data on more than 18 diseases and a substantial number of injury types. In fact, Leigh used more than 40 data sets in conducting this rigorous analysis.
While the Leigh study is the most comprehensive analysis of the burden of occupational illness and injury in the U.S. ever conducted, the estimates, due to methodologic issues inherent in the data, still do not capture the full economic burden. As Leigh indicated, the cost estimates did not include:
- employer costs for labor turnover, retraining and hiring
- dementia, depression, diseases of the nervous system, osteoarthritis
- the impact on productivity of “presenteeism”
- the costs of pain and suffering
Although these exclusions were justifiable for methodological reasons, the study finding of a $250 billion economic burden is an underestimate of the true burden of occupational illness and injury. Additionally, the Leigh study does not include the costs resulting from the interaction of occupational and personal risk factors (see previous blog: A Comprehensive Approach to Workforce Health) that lead to many diseases of public health importance. The paper by Leigh is a scholarly advance and the most rigorous to date, but due to the lack of complete data on the prevalence, incidence, and costs of all occupational illnesses and injuries, further methodological work is needed to capture, among other factors, the true attributable fraction. Identifying these exclusions and limitations of this study highlights the point that there is still much work to do in characterizing the true economic burden of occupational injury and illness.
This paper is a major step in illustrating the economic burden of occupational injury and illness and how this affects the economic health of the nation and the productivity of the workforce. Leigh observes that the cost of job-related injuries and illnesses are greater than generally assumed. However, the national investment in addressing occupational illness and injuries is far less than for many other diseases with lower economic burden even though occupational illnesses and injuries are eminently preventable.
As mentioned in the description of the NIOSH Economics Program the Occupational Safety and Health Act of 1970 (the Act) states:
“The Congress finds that personal injuries and illnesses arising out of work situations impose a substantial burden upon, and are a hindrance to, interstate commerce in terms of lost production, wage loss, medical expenses, and disability compensation payments.” [Section (2)(a)]
The paper by Leigh quantified the extent of that burden, which in part motivated the passage of the Occupational Safety and Health Act, and shows that this burden is still significant today. We welcome your comments and observations on the burden and the appropriate response to these observations.
