Abstract
Objective: Technical skills (TS) and non-technical skills (NTS) are the primary elements ensuring patient safety during advanced life support (ALS) and effective crisis resource management (CRM). Both skills are needed to perform high-quality ALS, though they are traditionally practiced separately. The evidence of the association between NTS and TS in high-quality ALS performance is insufficient. Hence, we aimed to evaluate the association between the skills in real-life in-hospital ALS situations.Methods: We video recorded real-life in-hospital ALS situations, analyzed TS and NTS demonstrated in them with an instrument measuring TS and NTS, and tested the linear association between NTS and TS using a linear mixed model.Results: Among 50 real-life in-hospital ALS situations that we recorded, 20 had adequate data for analysis. NTS and TS total scores were associated with one another (slope 0.48, P < 0.001). All NTS subcategories were associated with the TS total score (slopes ranging from 0.29 to 0.39, P < 0.001). The NTS total score and TS subcategories (chest compression quality, ventilation quality, rhythm control and defibrillation quality) were associated with one another (slopes ranging from 0.37 to 0.56, P < 0.01).Conclusions: The resuscitation teams who demonstrated good NTS also performed the technical aspects of ALS better. The results suggest that NTS and TS have an association with one another in real-life in-hospital ALS situations. NTS performance had the most evident association with chest compression quality and rhythm control and defibrillation quality; these are considered the most crucial elements affecting outcomes of ALS. The findings of the study present novel information of what and why to emphasize in ALS training.Clinical Trial Registration: ClinicalTrials.gov, NCT03017144. [ABSTRACT FROM AUTHOR]
