The aim of the study reported here was to address the need to assess and train teamwork and non-technical skills in the context of Resuscitation. Specifically, we sought to develop a tool that is feasible to use and psychometrically sound to assess team behaviours during cardiac arrest resuscitation attempts.
To ensure validity, reliability, and feasibility, the Observational Skill based Clinical Assessment tool for Resuscitation (OSCAR) was developed in 3 phases. A review of the literature leading to initial tool development was followed by an assessment of face and content validity, and finally a thorough reliability assessment, using Cronbach's α to assess internal consistency and intraclass correlation to assess inter-rater reliability.
OSCAR was developed methodically, and tested for face and content validity. Cronbach's α results ranged from 0.736 to 0.965 demonstrating high internal consistency, and intraclass correlation results ranged from 0.652 to 0.911, all of which are strongly significant and indicate good inter-rater reliability.
On the basis of our results, we conclude that OSCAR is psychometrically robust, scientifically sound, and clinically relevant. We have developed the Observational Skill-based Clinical Assessment tool for Resuscitation (OSCAR) for the assessment of non-technical skills in Resuscitation teams. We propose the use of this tool in simulation and real Cardiac Arrest Resuscitation attempts to assess, guide and train non-technical skills to team members, to improve patient safety and maximise the chances of successful resuscitation.
本研究旨在评估和培训复苏背景下的团队合作和非技术技能。具体而言，我们旨在开发一种可行的工具，以评估团队在心脏骤停复苏尝试期间的行为，并具有良好的心理测量学特性。
为了确保有效性、可靠性和可行性，观察技能为基础的复苏临床评估工具（OSCAR）分三个阶段开发。在进行初始工具开发之前，对文献进行了回顾，随后对其进行了表面和内容有效性评估，最后进行了彻底的可靠性评估，使用 Cronbach 的 α 评估内部一致性，使用组内相关评估评分者间可靠性。
OSCAR 是经过系统方法开发和测试的，具有表面和内容有效性。Cronbach 的 α 结果范围为 0.736 至 0.965，表明具有高度的内部一致性，而组内相关结果范围为 0.652 至 0.911，均具有统计学意义，表明评分者间可靠性良好。
基于我们的结果，我们得出结论，OSCAR 具有良好的心理测量学特性、科学性和临床相关性。我们已经开发了观察技能为基础的复苏临床评估工具（OSCAR），用于评估复苏团队的非技术技能。我们建议在模拟和真实的心脏骤停复苏尝试中使用此工具，以评估、指导和培训团队成员的非技术技能，提高患者安全性并最大限度地提高复苏成功的机会。
