Does high-fidelity human patient simulation improve the time to resolve simulated anesthetic crises in anesthesiology trainees using new equipment?
Using a high-fidelity human patient simulator to introduce new anesthesia equipment significantly reduces the time to resolve simulated crises, suggesting a reduction in learning-curve errors.

Supports high-fidelity simulation for new anesthesia equipment training; extends RCT evidence on simulation shortening crisis resolution times.
In Brief New anesthesia delivery systems are becoming increasingly complex. Although equipment is involved in a large proportion of intraoperative anesthesia problems (most also involving human error), the current methods of introducing new equipment into clinical practice have not been well studied. We designed a randomized, controlled, prospective study to investigate an alternative method of introducing new anesthesia equipment. Fifteen anesthesiology trainees were randomized to either the standard introduction to a Dräger Fabius GS anesthesia delivery machine plus simulated clinical use of the new machine in a high-fidelity human patient simulator (HPS) (Group 1) or to the standard introduction alone (Group 2). We used a questionnaire to seek their opinion on the new equipment, and responses showed that both groups were comparable in their reported confidence to use the new equipment safely. All trainees were then tested in two simulated anesthetic crises with the new machine. Performance was analyzed in terms of time to resolve the emergency, by using analysis of videos by an independent rater. Group 1 resolved both crises significantly faster. HPS allowed us to detect design features that were common sources of error. IMPLICATIONS: A human patient simulator may reduce the risk of learning-curve error in anesthesiologists using new, complex equipment without subjecting patients to risk. It can be used to highlight potential design errors in new equipment through usability testing or certify practitioners before they use new equipment.

Dalley et al. (2004) conducted an RCT in Anesthesiology training (n=15). High-fidelity human patient simulator (HPS) training vs. Standard introduction alone was evaluated on Time to resolve the emergency in two simulated anesthetic crises. High-fidelity human patient simulation training allowed anesthesiology trainees to resolve simulated anesthetic crises significantly faster compared to standard introduction alone.
