概括
使用社交网络分析 (SNA) 针对关键影响者,在手术室护士中显著改善了手部卫生遵守 (HHC),减少了手术部位感染 (SSI). 这种精确的方法为传统的感染控制计划提供了一个可持续的,资源高效的替代方案.
科学领域:
- 医疗保健管理的管理
- 感染控制 感染控制
- 网络科学 网络科学
背景情况:
- 在手术室 (ORs) 中,低于最佳的手部卫生遵守 (HHC) 是手术部感染 (SSI) 的主要原因.
- 改善HHC的传统干预措施往往缺乏长期可持续性.
- 社交网络分析 (SNA) 提供了一种新的方法来识别和利用行为改变的关键影响者.
研究的目的:
- 评估SNA信息干预措施的有效性,以改善OR护士之间的HHC.
- 评估干预对SSI率和团队气候的影响.
- 使用精确方法来确定HHC改进的可持续性.
主要方法:
- 一个为期12个月的集群随机对照试验与两个医院校区的86名OR护士进行.
- 使用SNA (加权在程度和中间中心性) 识别了关键影响者 (KIs),并作为同行冠军进行培训.
- 手部卫生遵守率 (HHC) 通过在基线和3,6和12个月的秘密观察来测量.
主要成果:
- 干预组和对照组之间的基线HHC是可比的 (约. 百分之四十二) 的比例.
- 根据SNA的干预措施,12个月后HHC显著增加到79.2%,而对照组的59.3% (p<0.001).
- 干预组的SSI率相对下降了43.2%,护士知识和团队气氛显著改善.
结论:
- 通过SNA确定关键影响者的准是改善和维持OR护士中HHC的高度有效策略.
- 这种精确,以影响者为导向的方法为传统的感染控制计划提供了一个资源高效的替代方案.
- 基于SNA的干预可以导致SSI的显著减少,并改善外科环境中的整体团队环境.

Hand hygiene
6.4K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail...

PPE Use in Healthcare Settings II: Doffing
1.7K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Effective communication among healthcare professionals during hand-off reporting is essential to delivering safe and continuous patient care. Common professional interactions include reports to healthcare team members, hand-off, and transfer reports. Nurses routinely report information to other healthcare team members and also urgently contact healthcare providers to report changes in patient status.
