Effects of a participatory ergonomics team among hospital orderlies

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.
