Learning through simulated independent practice leads to better future performance in a simulated crisis than...

Area of Science:

• Medical Education
• Patient Safety
• Anesthesiology

Background:

• Rare intraoperative events pose challenges for anaesthetists.
• Simulation is an effective adjunct for training but the reasons for its benefit are unclear.
• Independent practice with simulated failure may enhance learning outcomes.

Purpose of the Study:

• To investigate if allowing anaesthesiology residents to manage a simulated rare intraoperative event independently, including experiencing simulated patient harm, improves subsequent performance.
• To compare the effectiveness of independent simulation-based learning versus supervised simulation in managing critical events.

Main Methods:

• A randomized, controlled, observer-blinded study involving 24 first-year anaesthesiology residents.
• Participants were assigned to an independent group (managed scenario with harm) or a supervised group (attending intervention).
• Performance was assessed 6 months later on a similar scenario, measuring proper treatment, time to diagnosis, and non-technical skills (ANTS).

Main Results:

• No participants initially provided proper treatment.
• In the repeat encounter, 67% of the independent group vs 17% of the supervised group resumed adequate oxygen delivery (P=0.013).
• The independent group demonstrated significantly better Anaesthetists' Non-Technical Skills (ANTS) scores (P=0.015).

Conclusions:

• Allowing anaesthesiology residents to practice independently and experience simulated failure is a valuable component of simulation-based learning.
• This approach, though not feasible in real clinical practice, significantly improved resident performance in managing critical events.
• Purposeful independent practice with potential negative outcomes differentiates simulation-based learning from traditional operating room education.
