Does Teamwork Mediate Relationship between Partner Familiarity and EMT Injuries?

描述(由申请人提供)：急救医疗技术人员(EMT)在工作中死亡和受伤的风险比普通民众大得多。每年，每10万名急救人员中有12.7人因公死亡；这一比率是全国工作场所平均水平的两倍多。在工作中，疾病、背部扭伤、针刺和其他非致命伤害影响到全国每100名急救人员中的3.0%至8.1人。在一些急救机构中，非致命性伤害的年发生率已经达到流行的比例，其比率已经上升到34%以上。有理由相信，伴侣的熟悉度和团队合作与受伤有关。在一些机构，急救员每年可能与50多个不同的合作伙伴合作，并与该机构的其他合作伙伴接触有限。在这种情况下，急救医生可能从未一起接受过培训，对伴侣的专业知识了解有限。航空界先前的研究将这种配置与事故、错误和团队合作不佳联系在一起。在EMS中不存在类似的研究。我们假设致命和非致命的EMT伤害更多地发生在不熟悉的合作伙伴和未能参与积极的团队合作行为(如频繁沟通)的合作伙伴中。我们致力于实现以下目标：1)研究急救人员对伴侣的熟悉程度与致命性和非致命性伤害之间的关系。为此，我们将访问美国最大的救护车公司(www.AMR.net)的员工轮班记录和OSHA 300伤害日志的主数据库。500个EMT的样本大小使超过99%的能力检测到熟悉程度中1个标准差变化的伤害的赔率比为2.0。目的2)：考察合作伙伴熟悉度与EMT团队合作知觉之间的关系。目标3)：研究伴侣熟悉度、团队合作意识和受伤之间的关系。我们有一个独特的机会，通过建立基准数据和回答以前在已发表的文献中未得到回答的问题，为文学做出重大贡献并影响行业。我们将利用这项研究的结果开发一个R01应用程序来测试伤害和安全计划的有效性，该计划以伴侣熟悉度、团队合作和伤害之间的关系为条件。 公共卫生相关性：与普通民众相比，急救医务人员在工作中死亡和受伤的风险明显更大。急救医生是独一无二的，因为随着时间的推移，他们以两人一组的方式工作，有不同的合作伙伴。我们认为，EMT合作伙伴之间缺乏熟悉和团队合作是导致受伤的原因之一。我们将用美国最大的私人救护车公司的数据来检验这一假设。我们将根据这个项目的结果制定伤害预防计划。好了！

DESCRIPTION (provided by applicant): Emergency Medical Technicians (EMTs) are at a significantly greater risk of death and injury at work than the general population. Annually, 12.7 out of every 100,000 EMTs die in the line of duty; a rate more than twice the national workplace average. On the job illnesses, back sprains, needle sticks, and other non-fatal injuries affect between 3.0 and 8.1 out of every 100 EMTs nationwide. The annual rate of non-fatal injuries has reached epidemic proportions in some EMS agencies, where the rate has risen to over 34%. There is reason to believe that partner familiarity and teamwork are associated with injury. In some agencies, EMTs may work with more than 50 different partners annually and have limited exposure to other partners in the agency. In these situations, EMTs may have never trained together and work with a limited understanding of their partner's expertise. Prior research in aviation link this type of configuration to accidents, errors, and poor teamwork engagement. Similar research in EMS does not exist. We hypothesize that fatal and non-fatal EMT injuries occur more frequently among less familiar partners and among partners that fail to engage in positive teamwork behaviors such as frequent communication. We seek to accomplish the following aims: We aim to 1) examine the relationship between partner familiarity and fatal and non-fatal injuries among EMTs. For this aim, we will access a master database of employee shift records and OSHA 300 injury logs from the nation's largest ambulance corporation (www.AMR.net). A sample size of 500 EMTs gives over 99% power to detect an odds ratio of injury of 2.0 for a 1- standard deviation change in familiarity. Aim 2): To examine the relationship between partner familiarity and EMT perceptions of teamwork. Aim 3): Examine the relationship between partner familiarity, perceptions of teamwork, and injuries. We have a unique opportunity to make a significant contribution to the literature and impact the industry by establishing benchmarking data and answer questions previously unanswered in the published literature. We will use this study's findings to develop an R01 application to test the effectiveness of injury and safety programs conditioned on the relationships between partner familiarity, teamwork, and injury. PUBLIC HEALTH RELEVANCE: Emergency Medical Technicians (EMTs) are at a significantly greater risk of death and injury at work than the general population. EMTs are unique because they work in teams of two with different partners over time. We believe that lack of familiarity and teamwork among EMT partners contributes to injuries. We will test this hypothesis with data from the nation's largest private ambulance company. We will develop injury prevention programs conditioned on findings from this project. !
