Extended work hours and risk of acute occupational injury: A case-crossover study of workers in manufacturing AMERICAN JOURNAL OF INDUSTRIAL MEDICINE Vegso, S., Cantley, L., Slade, M., Taiwo, O., Sircar, K., Rabinowitz, P., Fiellin, M., Russi, M. B., Cullen, M. R. 2007; 50 (8): 597-603

Abstract

This study was designed to determine whether injury risk among manufacturing workers was related to hours worked during the previous week.A case-crossover design was utilized to contrast hours worked prior to an injury shift with those worked prior to a non-injury shift for hourly workers. Paired t-tests were used to determine significance of the difference. Conditional logistic regression was used to assess dose-response.Hours worked prior to injury significantly exceeded hours during the control week. Workers who worked more than 64 hr in the week before the shift had an 88% excess risk compared to those who worked 40 hr or fewer, P < 0.05.The study provides evidence that injury risk is related to time worked during the previous week. Control of overtime in manufacturing may reduce risk of worker injury.
