A Supplementary Data System (SDS) developed by the US Bureau of Labor Statistics to associate repetitive motion related hand and wrist disorders with specific industries and occupational groups is described. The SDS was derived from state records of workers' compensation claims which involved the occurrence of soft tissue disorders of the wrist or hand. Data from 26 states reporting current case claims for the year 1979 were used for this assessment. To be acceptable for inclusion in the study, a wrist compensation claim had to involve inflammation or irritation of joints, tendons, muscles, or to diseases of the nerves and peripheral ganglia. All disorders had to be attributable to some non impact type of accident. A total of 3,027 compensation claims reported in 1979 met the criteria. The manufacturing industry accounted for about 70 percent of the claims with a ratio of 23.8 claims per 100,000 workers. The construction industry, with an incidence ratio of 10.1 claims per 100,000 workers, was the second highest contributor. Agriculture, with 9.6 claims per 100,000 workers, was the only other industrial sector with a ratio higher than the overall 9.4 claims per 100,000 average. The major industrial categories were also broken down according to standard industrial classification codes in order to identify high risk occupations. Meatcutters and butchers were by far at the highest risk for filing non impact wrist disorder claims, with 498.8 claims per 100,000 workers. Miscellaneous laborers and bottling or canning operators, with 167.0 and 101.8 claims per 100,000 workers, respectively, were the next highest risk occupations.
