Anaesthesia·2013

Doctor confidence can decrease during difficult medical tasks, even when performance is good. This dynamic confidence loss highlights a need for training to maintain confidence during complex procedures.

Area of Science:

  • Medical Education
  • Clinical Performance
  • Human Factors in Medicine

Background:

  • Physician confidence is crucial for effective clinical practice.
  • Static confidence has been extensively researched, but dynamic changes during tasks remain understudied.

Purpose of the Study:

  • To investigate the dynamic changes in trainee anaesthetists' confidence during simulated clinical crises.
  • To compare confidence fluctuations between novice and experienced trainees.

Main Methods:

  • Confidence levels of 20 trainee anaesthetists (10 novice, 10 experienced) were measured.
  • Measurements were taken during two simulated anaesthetic crises: bradycardia (easy) and failure to ventilate (difficult).

Main Results:

  • Confidence was high for both groups during the easy bradycardia task.
  • Surprisingly, confidence decreased in both novice and experienced groups during the difficult failure to ventilate task, despite adequate performance.

    • Conclusions:

    • The rapid decline in dynamic confidence during challenging procedures is concerning, especially for unsupervised practitioners.
    • Training interventions are necessary to prevent inappropriate confidence loss during correctly executed procedures.
    • Further research should explore the interaction between time on task, performance errors, and confidence deficits.
