背景:皇家麻醉师学院(NAP7)的第7个国家审计项目建议在所有麻醉场所立即使用紧急呼叫系统。至关重要的是,所有剧院团队成员都可以迅速寻求帮助,以减少患者受到伤害的风险。然而,员工及时激活该系统的能力可能会受到混乱或不熟悉的环境和认知过载的影响。一种提出的能够快速识别和激活紧急呼叫系统的策略是在从天花板到激活按钮的墙壁上安装红色垂直涂漆条纹。我们调查了在英国和澳大利亚的手术室中引入垂直红线对激活时间的影响。
方法:手术室团队成员,包括麻醉师,外科医生,麻醉护士,外科和手术室护士,手术室从业者,和技术人员,在没有事先警告的情况下被接近,并被要求模拟紧急呼叫的激活。安装了垂直红线,4-12个月后在相同的手术室重复数据收集。
结果:安装垂直红线后,激活>10s的比例从31.9%(30/94)下降到13.6%(17/125,P=0.001),>20s从19.1%(18/94)下降到4.8%(6/125,P<0.001)。预安装时间最长为120秒,和安装后35秒。
结论:这个简单,安全,廉价的设计干预应被视为所有手术室的设计标准,以最大程度地减少寻求帮助的延误。
BACKGROUND: The 7th National Audit Project of the Royal College of Anaesthetists (NAP7) recommended that an emergency call system be immediately accessible in all anaesthesia locations. It is essential that all theatre team members can rapidly call for help to reduce the risk of patient harm. However, the ability of staff to activate this system in a timely manner can be affected by cluttered or unfamiliar environments and cognitive overload. One proposed strategy to enable rapid identification and activation of emergency call systems is to install a red vertical painted stripe on the wall from the ceiling to the activation button. We investigated the effect of introducing this vertical red line on activation times in operating theatres in the UK and Australia.
METHODS: Operating theatre team members, including anaesthetists, surgeons, anaesthetic nurses, surgical and theatre nurses, operating theatre practitioners, and technicians, were approached without prior warning and asked to simulate activation of an emergency call. Vertical red lines were installed, and data collection repeated in the same operating theatres 4-12 months later.
RESULTS: After installation of vertical red lines, the proportion of activations taking >10 s decreased from 31.9% (30/94) to 13.6% (17/125, P=0.001), and >20 s decreased from 19.1% (18/94) to 4.8% (6/125, P<0.001). The longest duration pre-installation was 120 s, and post-installation 35 s.
CONCLUSIONS: This simple, safe, and inexpensive design intervention should be considered as a design standard in all operating theatres to minimise delays in calling for help.
