Simulation-based training in anaesthesiology: a systematic review and meta-analysis

Area of Science:

• Medical Education
• Anesthesiology Training
• Simulation-Based Learning

Background:

• Simulation is widely used in anesthesiology training.
• A comprehensive review of its effectiveness is needed.
• Evidence synthesis is crucial for optimizing training strategies.

Purpose of the Study:

• To synthesize evidence on the effectiveness of simulation-based anesthesiology training.
• To compare simulation with no intervention and non-simulation instruction.
• To analyze the impact of different simulation instructional designs.

Main Methods:

• Meta-analysis and critical narrative analysis of 77 studies (6066 participants).
• Searched MEDLINE, ERIC, and SCOPUS databases through May 2011.
• Included studies training health professionals using simulation.

Main Results:

• Simulation showed moderate to large effect sizes (ESs) compared to no intervention (ES range 0.60-1.05), except for patient outcomes (ES -0.39).
• Compared to non-simulation instruction, simulation had moderate effects on satisfaction and skills (ES 0.39-0.42) and a large effect on behaviors (ES 1.77).
• Instructional designs, such as debriefing methods and inclusion of non-technical skills, showed negligible effects in some comparisons.

Conclusions:

• Simulation in anesthesiology is more effective than no intervention (excluding patient outcomes) and non-inferior to non-simulation instruction.
• Current evidence suggests simulation enhances skills and behaviors but patient outcomes require further investigation.
• Key instructional designs for simulation-based anesthesiology training remain unclear, necessitating further research.
