Simulation training significantly improves coronary anastomosis skills and efficiency for surgeons. Novice surgeons show greater time improvements compared to senior surgeons with simulation-based learning.
Area of Science:
- Cardiovascular Surgery
- Medical Simulation
- Surgical Education
Background:
- Coronary artery anastomosis is crucial for patient safety and outcomes.
- Effective training and assessment are essential for surgical proficiency.
Purpose of the Study:
- To systematically review and meta-analyze the impact of simulation on coronary anastomosis proficiency.
- To assess improvements in time taken and skill scores.
Main Methods:
- Systematic review and meta-analysis following PRISMA guidelines.
- Searched PubMed, Embase, and Cochrane databases.
- Included studies with objective pre- and post-simulation measurements.
Main Results:
- Simulation training improved skill scores (SMD 1.68) and reduced time (MD 205.9s) compared to no training.
- Novice surgeons experienced greater time improvements (293s) than senior surgeons (120s).
- Simulator fidelity did not significantly affect improvement rates.
Conclusions:
- Simulation-based training enhances coronary anastomosis efficiency and performance.
- Further research is needed to define optimal progression from simulation to live operating.
