Standard morbidity ratios for work-related amputations and fractures by occupation, 1979-1981.
J Saf Res 1988 Sep; 19(3):103-113
Data from the Supplementary Data System and census reports were used to calculate standard morbidity ratios (SMRs) for amputations and fractures according to occupation in 30 states for the period 1979 to 1981. SMRs exceeding 100 within each state were then ranked to identify occupations with a high risk of amputation or fracture injuries. Occupations in which workers were exposed to a higher than expected risk of amputation included mine operators, machinists, meat cutters, laborers, heavy equipment mechanics, cutting operators, food service employees, plumbers, material handlers, operatives, and firefighters. Occupations in which workers were exposed to a higher than expected risk of fractures included, in addition to the previous listing, lumbermen, construction workers, metal workers, road machine operators, and bus drivers. When ranked according to the percentage of states in which an occupation had SMRs greater than 100 for amputations, the range was from 73.3 to 3.3 percent with machinists being the highest, followed by heavy equipment mechanics and mine operators, with firefighters and meat cutters being the lowest. When ranked according to the percentage of states in which an occupation had SMRs greater than 100 for fractures, the range was from 100.0 to 3.3 percent and included plumbers and food service workers as the highest, decreasing to cutting operators and road machine operators at the lower end of the range. The author concludes that age and sex adjusted SMRs are useful for showing injury patterns and are more specific than other data sources which do not account for confounding by age or sex.
