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.

This is a mixed methods assessment study to be completed at TWH. We will recruit 10 fellowship-trained regional anesthesiology and pain medicine staff anesthesiologists to perform USGRA blocks while being video-recorded. Here, we specifically define expert as a staff anesthesiologist who has completed a fellowship in regional anesthesia and/or chronic pain and has at least 6-years of post-fellowship clinical experience with USGRA. Consent will also be sought from 180 patients undergoing USGRA for surgical procedures at TWH to have the block completed by an expert, as previously defined, and to have the procedure recorded.
