简要总结
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.

结局指标
主要结局
Difference between pre- and post-intervention image acquisition and interpretation skill (as compared to the benchmark exam).
时间窗: ~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: * Scanning time (total and per view) * Anatomy recognition * Items completion (%) * Image interpretation (Y/N for lung sliding, interstitial syndrome, pleural effusion, consolidation, pericardial fluid, LV global function, RV global function, intravascular volume assessment; total and per objective accuracy) * MCQs results (%) (Indication \& Image interpretation assessment) * Video-interpretation of cases results (%) (Image interpretation \& Clinical decision-making assessment) * Qualitative and quantitative analysis of survey results (dichotomic questions; graded criteria; e.g.10-point Likert scale)
次要结局
- Differences between self-directed and simulation-assisted training and traditional apprenticeship training(~4-5 months post-study enrolment, after completion of ultrasound training)
