背景非技术技能对于良好的麻醉实践至关重要，但在正常培训中没有明确说明。人们日益认识到需要培训和评估这些技能，但这些活动必须以适当制定的技能框架和经过验证的衡量工具为基础。一个原型的行为标记系统开发使用人为因素的研究技术。本研究的目的是进行实验评估，以建立其基本的心理测量学特性和可用性。麻醉师非技术技能（ANTS）系统原型包括四个技能类别（任务管理，团队合作，态势感知和决策），分为15个元素，每个元素都有示例行为。为了调查其实验的有效性，可靠性和可用性，50名顾问麻醉师，接受培训，使用ANTS系统。他们被要求在八个模拟麻醉场景的视频中使用原型系统对目标麻醉师的行为进行评级。从评分表和评估表中收集数据。结果表明，该系统是完整的，技能是可观察的，可以在可接受的一致性和准确性水平上进行评级。该系统的内部一致性似乎是健全的，关于可用性的反应是非常积极的。评价结果表明，ANTS系统在实验环境中具有令人满意的有效性、可靠性和可用性，只要用户得到充分的培训。它现在已经准备好在真实的培训环境中进行测试，以便制定完整的指南，将其整合到麻醉课程中。
Background. Non-technical skills are critical for good anaesthetic practice but are not addressed explicitly in normal training. Realization of the need to train and assess these skills is growing, but these activities must be based on properly developed skills frameworks and validated measurement tools. A prototype behavioural marker system was developed using human factors research techniques. The aim of this study was to conduct an experimental evaluation to establish its basic psychometric properties and usability.Method. The Anaesthetists' Non-Technical Skills (ANTS) system prototype comprises four skill categories (task management, team working, situation awareness, and decision making) divided into 15 elements, each with example behaviours. To investigate its experimental validity, reliably and usability, 50 consultant anaesthetists; were trained to use the ANTS system. They were asked to rate the behaviour of a target anaesthetist using the prototype system in eight videos of simulated anaesthetic scenarios. Data were collected from the ratings forms and an evaluation questionnaire.Results. The results showed that the system is complete, and that the skills are observable and can be rated with acceptable levels of agreement and accuracy. The internal consistency of the system appeared sound, and responses regarding usability were very positive.Conclusions. The findings of the evaluation indicated that the ANTS system has a satisfactory level of validity, reliability and usability in an experimental setting, provided users receive adequate training. It is now ready to be tested in real training environments, so that full guidelines can be developed for its integration into the anaesthetic curriculum.
