Warm-up in a virtual reality environment improves performance in the operating room

Area of Science:

• Surgical Education
• Minimally Invasive Surgery
• Medical Simulation

Background:

• Simulation-based training shows skill transfer to the operating room (OR), but implementation is limited.
• Virtual reality (VR) simulators offer a platform for surgical skill development.
• Assessing the impact of VR warm-up on laparoscopic performance in the OR is crucial.

Purpose of the Study:

• To evaluate the impact of a brief VR warm-up program on laparoscopic performance.
• To determine if preoperative VR training enhances surgical skills in the OR.
• To assess the feasibility of implementing VR warm-up in a busy surgical department.

Main Methods:

• Eight surgeons performed 16 laparoscopic cholecystectomies in the OR.
• Surgeons were randomized to either a VR warm-up group or a no warm-up control group.
• Procedures were videotaped and assessed using the Objective Structured Assessment of Technical Skills (OSATS) global rating scale.

Main Results:

• Surgical performance was significantly better after preoperative VR warm-up (median 28.5 vs. 19.25, P=0.042).
• The assessment tool demonstrated high reliability (Cronbach's alpha = 0.92).
• The VR warm-up program was short and easy to perform.

Conclusions:

• Preoperative VR warm-up has a significant beneficial impact on laparoscopic performance.
• This VR warm-up program is practical for integration into daily surgical practice.
• Implementation can lead to improved procedural outcomes, patient safety, and OR resource utilization.
