title: Evaluation of occupational injuries in an urban emergency medical services system before and after implementation of electrically powered stretchers.
abstract: Musculoskeletal injuries are frequently reported among Emergency Medical Services (EMS) professionals. The objective of this study was to evaluate occupational injuries in an urban EMS system before and after implementation of hydraulic stretchers. Data for this analysis were obtained from Austin Travis County EMS (A/TCEMS). In December 2006, A/TCEMS placed into service electrically powered patient stretchers. The pre-intervention period was between 01/01/1999 and 12/31/2006, and the post-intervention period was between 01/01/2007 and 4/30/2008. Incidence rate calculations were performed for four injury sub-groups and rate ratios (RRs) and corresponding 95% confidence interval (CI) were presented. There were 2087 and 706 person-years of observation pre- and post-intervention, respectively. The incidence rates for overall injury pre-intervention and post-intervention were 61.1 and 28.8 per 100 FTE, with a corresponding RR of 0.47 (95% CI 0.41-0.55) indicating a significant decrease in the rate of injury. The subcategory of stretcher-related injuries had the lowest RR (0.30; 95% CI 0.17-0.52) when comparing pre- and post-intervention time periods.
