Epidemiology of foot and ankle injuries in the workplace.

Injuries to the ankle, foot, and toes of injured workers are common. Although the workers' compensation system attempts to collect information about these injuries and report them in a meaningful way, the process is somewhat inconsistent, inaccurate, and provides information relevant to government agencies but not to physician organizations seeking to improve the prevention and treatment of work-related injuries. Several improvements in data collection could greatly increase the system's efficiency and usefulness. The first is to establish a national system of uniform data collection from each State. The second improvement involves standardization of the forms and means that the data are collected from the worker including a system to retrieve information that has been omitted during the initial encounter. The third, and most important, refinement is to change the reporting of the illness to match currently accepted medical diagnosis codes (ICD-9). Using the current system and making these improvements, the United States would be able to collect more meaningful data on work injuries in this country. From that point forward medical interventions could then be created and their effects more meaningfully analyzed. All those involved in the care and treatment of the injured worker must recognize not only the limitations of the collected data but also how this information can be manipulated. For example, whereas the total cost of benefits paid by employers increased during one decade the average cost per covered employee decreased. Employers and insurers can argue that their total costs have consistently risen but only by knowing that the cost per covered employee had decreased during that same time period can that argument be countered. Similarly, implementation of certain safety practices during a given time period may be accompanied by a reduction in the number of injuries. Changes in the laws that altered injury reporting and reduced the coverage for certain injuries, however, may have created a situation where the reported injury rates were reduced by accounting practice, not medical practice. It is also well established that insurance company profits may be linked as much to the general economy and stock market as they are to premiums and claims. It is hoped that this article begins an understanding of the extent of the problem of foot and ankle injuries in the working population. Additional statistical information on specific topics is presented elsewhere in this issue.
