Development and applications of the Anaesthetists' Non-Technical Skills behavioural marker system: a systematic review.

Abstract

To comprehensively synthesise evidence regarding the validity and reliability of the Anaesthetists' Non-Technical Skills (ANTS) behavioural marker system and its application as a tool for the training and assessment of non-technical skills to improve patient safety. Systematic review. We employed a citation search strategy. The Scopus and Web of Science databases were searched for articles published from 2002 to May 2022. English-language publications that applied the ANTS system in a meaningful way, including its use to guide data collection, analysis and reporting. Study screening, data extraction and quality assessment were performed by two independent reviewers. We appraised the quality of included studies using the Joanna Briggs Institute Critical Appraisal Checklists. A framework analysis approach was used to summarise and synthesise the included articles. 54 studies were identified. The ANTS system was applied across a wide variety of study objectives, settings and units of analysis. The methods used in these studies varied and included quantitative (n=42), mixed (n=8) and qualitative (n=4) approaches. Most studies (n=47) used the ANTS system to guide data collection. The most commonly reported reliability statistic was inter-rater reliability (n=35). Validity evidence was reported in 51 (94%) studies. The qualitative application outcomes of the ANTS system provided a reference for the analysis and generation of new theories across disciplines. Our results suggest that the ANTS system has been used in a wide range of studies. It is an effective tool for assessing non-technical skills. Investigating the methods by which the ANTS system can be evaluated and implemented for training within clinical environments is anticipated to significantly enhance ongoing enhancements in staff performance and patient safety.
