Hospital-acquired infections (HAIs) affect millions of patients annually (World Health Organization. Guidelines on Hand Hygiene in Healthcare. Geneva: WHO Press; 2009). Hand hygiene compliance of clinical staff has been identified by numerous studies as a major contributing factor to HAIs around the world. Infection control and hand hygiene in the prehospital environment can also contribute to patient harm and spread of infections. Emergency medical services (EMS) practitioners are not monitored as closely as hospital personnel in terms of hand hygiene training and compliance. Their ever-changing work environment is less favorable to traditional hospital-based aseptic techniques and education.
This study aimed to determine the current state of hand hygiene practices among EMS providers and to provide recommendations for improving practices in the emergency health services environment. This study was a prospective, observational prevalence study and survey, conducted over a 2-month period. We selected participants from visits to three selected hospital emergency departments in the mid-Atlantic region. There were two data components to the study: a participant survey and hand swabs for pathogenic cultures.
This study recruited a total sample of 62 participants. Overall, the study revealed that a significant number of EMS providers (77%) have a heavy bacterial load on their hands after patient care. All levels of providers had a similar distribution of bacterial load. Survey results revealed that few providers perform hand hygiene before (34%) or in between patients (24%), as recommended by the Centers for Disease Control and Prevention guidelines.
This study demonstrates that EMS providers are potential vectors of microorganisms if proper hand hygiene is not performed properly. Since EMS providers treat a variety of patients and operate in a variety of environments, providers may be exposed to potentially pathogenic organisms, serving as vectors for the exposure of their patients to these same organisms. Proper application of accepted standards for hand hygiene can help reduce the presence of microbes on provider hands and subsequent transmission to patients and the environment.
医院获得性感染(HAIs)每年影响数百万患者(世界卫生组织。《医疗保健中的手卫生指南》。日内瓦:世卫组织出版社;2009年)。众多研究已确定临床工作人员的手卫生依从性是全球医院获得性感染的一个主要促成因素。院前环境中的感染控制和手卫生也可能导致患者受到伤害并传播感染。在手部卫生培训和依从性方面,紧急医疗服务(EMS)从业者不像医院工作人员那样受到密切监测。他们不断变化的工作环境不太适合传统的基于医院的无菌技术和教育。
本研究旨在确定EMS提供者手部卫生实践的现状,并为改善紧急医疗服务环境中的实践提供建议。本研究是一项前瞻性观察性患病率研究和调查,为期2个月。我们从访问大西洋中部地区的三个选定医院急诊科中选取参与者。该研究有两个数据组成部分:参与者调查和用于病原菌培养的手部拭子。
本研究共招募了62名参与者作为样本。总体而言,研究表明,大量EMS提供者(77%)在护理患者后手上有大量细菌。各级提供者的细菌负荷分布相似。调查结果显示,很少有提供者按照疾病控制和预防中心的指南建议在护理患者前(34%)或在护理患者之间(24%)进行手卫生。
本研究表明,如果手部卫生操作不当,EMS提供者可能成为微生物的传播媒介。由于EMS提供者治疗各种患者并在各种环境中工作,他们可能接触潜在的致病生物,成为其患者接触这些相同生物的传播媒介。正确应用公认的手卫生标准有助于减少提供者手上的微生物数量,并随后减少向患者和环境的传播。
