Background:

Simulation-based training offers progressive, learner-centered, and patient-focused challenges for surgical trainees.
Designing effective simulation programs requires understanding surgical steps and assessing learner progress.
This study focuses on developing and validating performance assessment checklists for cardiac surgery simulation.

Purpose of the Study:

To design and validate performance assessment checklists for a progressive simulation-based cardiac surgery program.
To create content-specific assessment tools for each simulation scenario in a complex operative procedure.

Main Methods:

A case study design involved videotaping 10 off-pump coronary artery bypass procedures.
Procedures were deconstructed into teachable components, leading to 6 simulation scenarios.
Checklists were designed and validated using the Delphi technique with 11 cardiac surgery experts.

Main Results:

An in vivo workflow diagram was created, and 6 progressive simulation modules were developed.
Six assessment checklists were designed and validated, with an overall average score of 4.0 after two Delphi rounds.
All checklist items achieved consensus (≥3.5 rating), and final checklists contain 12–23 items.

Conclusions:

The feasibility of designing progressive simulation-based programs for complex surgical procedures has been demonstrated.
Predefined training objectives determined complexity at each level of the simulation program.
Validated assessment checklists serve as content-specific tools for evaluating trainee performance in cardiac surgery simulation.
