Evaluation of robotic cardiac surgery simulation training: A randomized controlled trial

Area of Science:

• Surgical Education
• Minimally Invasive Surgery
• Medical Simulation

Background:

• Robotic surgery is increasingly prevalent, necessitating effective training methods.
• Current simulation modalities for robotic surgery require objective comparison.
• Standardized assessment tools are crucial for evaluating surgical training.

Purpose of the Study:

• To compare the efficacy of different simulation training modalities for robotic surgery.
• To objectively assess the impact of wet lab, dry lab, and virtual reality simulation on surgical skills.
• To identify the most effective simulation methods for robotic surgery training.

Main Methods:

• Forty surgical trainees performed standardized robotic procedures (internal thoracic artery dissection, mitral valve annuloplasty).
• Trainees were randomized into wet lab, dry lab, virtual reality, or control groups.
• Proficiency was assessed by expert surgeons using the Global Evaluative Assessment of Robotic Skills (GEARS).

Main Results:

• Wet lab and virtual reality groups demonstrated significant improvements in performance metrics.
• Virtual reality simulation met expert-defined proficiency levels for all primary outcomes.
• The control group failed to achieve expert-level proficiency in time-based and objective scoring.
• Training duration varied significantly, with dry lab being shortest and virtual reality longest.

Conclusions:

• Wet lab and virtual reality simulation are highly beneficial for robotic surgery training.
• This study provides objective data to guide investment in cost-effective simulation exercises.
• Findings highlight key differences in current robotic surgery training methods, informing program development.
