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.
肌肉骨骼损伤在急救医疗服务（EMS）专业人员中经常报告。本研究的目的是评估液压担架实施前后城市 EMS 系统中的职业损伤。这项分析的数据来自奥斯汀特拉维斯县 EMS（A/TCEMS）。2006 年 12 月，A/TCEMS 投入使用电动患者担架。干预前时期为 1999 年 1 月 1 日至 2006 年 12 月 31 日，干预后时期为 2007 年 1 月 1 日至 2008 年 4 月 30 日。对四个损伤亚组进行了发病率计算，并提出了比率比（RR）和相应的 95%置信区间（CI）。干预前和干预后分别有 2087 人和 706 人年的观察期。干预前和干预后的总体损伤发生率分别为 61.1 和 28.8 例/100FTE，相应的 RR 为 0.47（95%CI 0.41-0.55），表明损伤率显著下降。在比较干预前后时间段时，担架相关损伤的亚类 RR 最低（0.30；95%CI 0.17-0.52）。
