The incidence of musculoskeletal injuries associated with computer use is increasing. Education has been advocated as a prevention method for reducing the incidence and severity of musculoskeletal injuries. Although the inclusion of education in musculoskeletal injury prevention programs has become a popular practice, the efficacy of educational programming is poorly defined in the literature. The present study was designed to investigate the efficacy of worker education programs in preventing musculoskeletal injuries in a population of reservation center employees who spend the majority of their work day using the computer. Participants were randomly assigned to one of three study groups (control, traditional education, or interactive education). Data collection utilized self-report surveys and observational checklists to collect data prior to intervention and at approximately 3, 6, and 12 months post intervention. Preliminary analysis of the data seems to indicate that, overall, education does have some impact on worker comfort, work area configuration, and worker postures.

Background: High rates of work‐related injuries are seen among health care workers involved in lifting and transferring patients. We studied the effects of a participatory worker–management ergonomics team among hospital orderlies. Methods: This prospective intervention trial examined work injuries and other outcomes before and after the intervention, with other hospital employees used as a concurrent control. All orderlies in a 1,200‐bed urban hospital were studied using passively collected data (mean employment during study period 100–110 orderlies); 67 orderlies (preintervention) and 88 orderlies (postintervention) also completed a questionnaire. The intervention was the formation of a participatory ergonomics team with three orderlies, one supervisor, and technical advisors. This team designed and implemented changes in training and work practices. Results: The 2‐year postintervention period was marked by decreased risks of work injury (RR = 0.50, 95% CI 0.35–0.72), lost time injury (RR = 0.26, 95% CI 0.14–0.48), and injury with three or more days of time loss (RR = 0.19, 95% CI 0.07–0.53). Total lost days declined from 136.2 to 23.0 annually per 100 full‐time worker equivalents (FTE). Annual workers' compensation costs declined from $237/FTE to $139/FTE. The proportion of workers with musculoskeletal symptoms declined and there were statistically significant improvements in job satisfaction, perceived psychosocial stressors, and social support among the orderlies. Conclusion: Substantial improvements in health and safety were seen following implementation of a participatory ergonomics program. Am. J. Ind. Med. 35:358–365, 1999. © 1999 Wiley‐Liss, Inc.
