The costs and circumstances of low-back strains, low-back impact
injuries, and non-low-
back injuries among field employees of an offshore
petroleum drilling company, 1979-1985, were compared. The objectives were to identify worker and workplace factors associated with low-
back injuries, to identify factors differentially associated with lost-time
injuries, and to formulate recommendations for the control of low-
back injuries. Low-back-impact
injuries resulted largely from falls. Efforts to prevent falls would have a potential to reduce other serious consequences as well as
back injuries. Workers performing the heaviest physical labor were at highest risk of low-back strains. Based on activities precipitating the injury, modifications of work site, equipment, and procedures to help reduce low-back strains are recommended. Only job was a predictor of whether a low-back strain was likely to be associated with lost time. Even this association was lacking for low-back impact
injuries. Cost control by preventing the small proportion of high cost
injuries may not be feasible. Rather, subsets of low-
back injuries defined, for example, by work site or activity can suggest options for intervention.
