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.

Outcome Measures

Primary Outcomes (8)

• Qualitative behaviors of experts performing UGRA techniques during pre-procedural discussion

  Reviewers will identify behaviors exhibited by the expert operators during pre-procedural discussion

  1 hour before procedure

• Qualitative behaviors of experts performing UGRA techniques during patient and equipment preparation

  Reviewers will identify behaviors exhibited by the expert operators during patient and equipment preparation

  0.5 hour before procedure

• Qualitative behaviours of experts performing UGRA techniques during ultrasound scanning of the target area;

  Reviewers will identify behaviors exhibited by the expert operators during ultrasound scanning of the target area;

  10 minutes before procedure

• Qualitative behaviours of experts performing UGRA techniques during needle advancement and local anesthetic deposition around the target nerve(s)

  Reviewers will identify behaviors exhibited by the expert operators during needle advancement and local anesthetic deposition around the target nerve(s).

  during procedure

• Quantitative data on block effectiveness defined by blocks requiring top-up

  number of top-up will be collected

  0-1 hour after procedure

• Quantitative data on block effectiveness defined by blocks requiring conversion to GA

  Incidence will be documented in case conversion to GA is needed

  0-1 hour after procedure

• Quantitative data on time to surgical anesthesia

  defined by final needle removal to surgical anesthesia

  0-1 hour after procedure

• Quantitative data on time to block completion

  defined by needle insertion to final needle removal

  0-1 hour after procedure

Eligibility Criteria

• Age: 18 Years - 80 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

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.

You may qualify if:

• All elective patients coming to the regional BR at TWH aged 18-80

You may not qualify if:

• Any contraindication to USGRA (LA allergy, patient refusal, infection at injection site, etc.)
• Inability to read or speak or comprehend English fluently
