Management of mental workload is a key aspect of safety in anaesthesia but there is no gold-standard tool to assess mental workload, risking confusion in clinical and research use of such tools.
This review assessed currently used mental workload assessment tools.
A systematic literature search was performed on the following electronic databases; Cochrane, EMBASE, MEDLINE, SCOPUS and Web of Science. Screening and data extraction were performed individually by two authors. We included primary published papers focusing on mental workload assessment tools in anaesthesia.
A total of 2331 studies were screened by title, 32 by full text and 24 studies met the inclusion criteria. Six mental workload measurement tools were observed across included studies. Reliability for the Borg rating scales and Vibrotactile device was reported in two individual studies. The rest of the studies did not record reliability of the tool measurements used. Borg rating scales, NASA-TLX and task-oriented mental work load measurements are subjective, easily available, readily accessible and takes a few minutes to complete. However, the vibrotactile and eye-tracking methods are objective, require more technical involvement, considerable time for the investigator and moderately expensive, impacting their potential use.
We found that the measurement of mental workload in anaesthesia is an emerging field supporting patient and anaesthetist safety. The self-reported measures have the best evidence base.
精神负荷管理是麻醉安全的关键方面，但目前尚无评估精神负荷的金标准工具，这可能导致此类工具在临床和研究应用中产生混淆。
本综述评估了目前使用的精神负荷评估工具。
对以下电子数据库进行了系统的文献检索；Cochrane、EMBASE、MEDLINE、SCOPUS和Web of Science。筛选和数据提取由两位作者分别进行。我们纳入了专注于麻醉中精神负荷评估工具的原始发表论文。
通过标题共筛选出2331项研究，通过全文筛选出32项，24项研究符合纳入标准。在所纳入的研究中观察到六种精神负荷测量工具。两项独立研究报告了博格评分量表和振动触觉装置的可靠性。其余研究未记录所使用工具测量的可靠性。博格评分量表、NASA - TLX和面向任务的精神工作负荷测量是主观的、易于获取、容易操作且只需几分钟即可完成。然而，振动触觉和眼动追踪方法是客观的，需要更多技术参与，对研究者来说耗时较长且成本适中，这影响了它们的潜在应用。
我们发现麻醉中精神负荷的测量是一个支持患者和麻醉医生安全的新兴领域。自我报告的测量方法有最好的证据基础。
