Focused Cardiac and Lung Ultrasound in Anesthesia/Critical Care - The Role of Self-directed Simulation-assisted Training Compared to a Traditional Supervised Approach
The purpose of this study is to determine whether a self-directed and simulation-based lung ultrasound (LUS) and focused cardiac ultrasound (FCU) curriculum is efficacious on anesthesia trainees' image acquisition skills and diagnostic acumen. The investigators hypothesize that a self-directed and ultrasound-assisted LUS and FCU curriculum that includes video lectures, online teaching modules, an ultrasound simulator, and self-directed hands-on sessions on critically ill mechanically ventilated patients is effective in training novice ultrasonographers to obtain good quality images, to correctly interpret them, and to support clinical decision-making in critically ill patients.
Trainees will be randomized to fully supervised FCU hands-on sessions on healthy models and critically ill mechanically ventilated patients (control group - traditional apprenticeship model) or to a completely self-directed and simulation-based approach (intervention group).
To assess if this new self-directed and simulation-based ultrasound curriculum leads to adequate acquisition of competences (adequate image acquisition and interpretation) in novice ultrasonographers, trainees will have to perform a focused lung and cardiac assessment on a critically ill mechanically ventilated patient.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Self-directed and simulation-assisted training
|
All participants will attend an ultrasound introductory course (lectures and illustrative interactive cases). Participants randomized to the intervention group will undergo a completely self-directed lung and focused cardiac ultrasound curriculum.
An investigator will supervise the sessions but will not interfere with the self-learning process. - To support their learning, trainees will have access to on-line virtual FCU and LUS modules created by the Toronto General Hospital Department of Anesthesia Perioperative Interactive Education (http://pie.med.utoronto.ca/TTE/index.htm). |
ACTIVE_COMPARATOR: Traditional apprenticeship training
|
All participants will attend an half-day ultrasound introductory course.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Difference between pre- and post-intervention image acquisition and interpretation skill (as compared to the benchmark exam).
Time Frame: ~4-5 months post-study enrolment, after completion of ultrasound training
|
The quality of the images will be scored from 1 (worst) to 5 (best). The score will be based on the assessment of the quality of the image as well as an assessment of relevant cardiac structures included in each view. Difference between pre- and post-intervention image acquisition skills and knowledge as measured by:
|
~4-5 months post-study enrolment, after completion of ultrasound training
|
