Expert Behaviors USGRA

• Conditions: Anesthesia Education

• Registration Number: NCT04454801
• Lead Sponsor: University Health Network, Toronto

Brief Summary

Expert-performance begins by focusing specifically on the end-product of training and experience in the hands of the expert. By defining expert behaviors and techniques, investigators can guide learners and non-expert practitioners by offering them models to emulate. At Toronto Western Hospital (TWH), there are more than ten expert attending regional anesthesiologists who routinely provide clinical patient care in the block room. The primary objective of this study is to qualitatively and quantitatively examine behavior of experts performing ultrasound guided regional anesthesia techniques to identify those which are consistent and unique, and which may underpin expert performance.

Primary Outcome Measures

Name	Time	Method
Qualitative behaviors of experts performing UGRA techniques during patient and equipment preparation	0.5 hour before procedure	Reviewers will identify behaviors exhibited by the expert operators during patient and equipment preparation
Qualitative behaviours of experts performing UGRA techniques during ultrasound scanning of the target area;	10 minutes before procedure	Reviewers will identify behaviors exhibited by the expert operators during ultrasound scanning of the target area;
Qualitative behaviours of experts performing UGRA techniques during needle advancement and local anesthetic deposition around the target nerve(s)	during procedure	Reviewers will identify behaviors exhibited by the expert operators during needle advancement and local anesthetic deposition around the target nerve(s).
Quantitative data on block effectiveness defined by blocks requiring top-up	0-1 hour after procedure	number of top-up will be collected
Quantitative data on block effectiveness defined by blocks requiring conversion to GA	0-1 hour after procedure	Incidence will be documented in case conversion to GA is needed
Quantitative data on time to surgical anesthesia	0-1 hour after procedure	defined by final needle removal to surgical anesthesia
Quantitative data on time to block completion	0-1 hour after procedure	defined by needle insertion to final needle removal
Qualitative behaviors of experts performing UGRA techniques during pre-procedural discussion	1 hour before procedure	Reviewers will identify behaviors exhibited by the expert operators during pre-procedural discussion
