Virtual Reality vs Technical Video in Surgical Training

NCT ID: NCT04404010

Last Updated: 2022-09-28

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 20 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2020-01-30
• Study Completion Date: 2020-02-01

Brief Summary

The use of instructional technical surgical videos is common in orthopaedic education. Many residents have used instructional technical surgical training videos prior to medical school, as well as during their residency program, and at instructional courses. The use of instructional technical surgical videos and multimedia is considered an adjunctive training method for orthopaedic residents to learn operative procedures.

Immersive virtual reality (iVR) is increasingly used in surgical education. Recently, iVR has shown transfer of skill training in orthopaedics. The continued study of the effectiveness of iVR training in orthopaedic education could benefit new competency based orthopaedics residency programs.

The purpose of this study is to compare the effectiveness of instructional technical surgical video training to immersive iVR training for teaching technical skills of reverse total shoulder arthroplasty. Our hypothesis was that iVR improved learning effectiveness compared to standard technical surgical video. Secondary objectives include validating a virtual reality ratings scale through correlation to real-world performance.

We proposed a randomized, blinded intervention-control trial directly comparing immersive iVR versus technical surgical instructional video training in the teaching of reverse shoulder arthroplasty in senior residents, learning at the 2020 annual Canadian Shoulder and Elbow Society meeting.

Detailed Description

Many residents have used instructional technical surgical training videos prior to medical school, as well as during their residency program, and at instructional courses.

Immersive virtual reality (iVR) is increasingly used in surgical education. Recently, iVR has shown transfer of skill training in orthopaedics. The continued study of the effectiveness of iVR training in orthopaedic education could benefit new competency based orthopaedics residency programs.

The purpose of this study is to compare the effectiveness of instructional technical surgical video training to immersive iVR training for teaching technical skills of reverse total shoulder arthroplasty. Our hypothesis was that iVR improved learning effectiveness compared to standard technical surgical video. Secondary objectives include validating a virtual reality ratings scale through correlation to real-world performance, and to determine efficiency of learning in both groups.

Currently, technical surgical instructional videos are pervasive in orthopaedic teaching education. Immersive VR, another form of teaching, is increasingly being used in surgical education. The production of an immersive VR suite with tactile and user metric feedback may be an advance over current bench top simulator technology, allowing for greater immersion and interaction, leading to better understanding of surgical planning and implementation. The development of this technology could provide trainees with immersive levels of training not previously seen, with improved learning of technical skills over media such as manufacturer technical documents. The effectiveness of training and efficiency of training of the novel immersive VR training systems need to be evaluated as they are increasingly incorporated into competency based, contemporary residency education.

We proposed a randomized, blinded intervention-control trial directly comparing immersive iVR versus technical surgical instructional video training in the teaching of reverse shoulder arthroplasty in senior (fourth and fifth year) residents, learning at the 2020 annual Canadian Shoulder and Elbow Society meeting.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: OTHER
• Blinding Strategy: SINGLE

Study Groups

Immersive Virtual Reality

Participants randomized to the immersive virtual reality (iVR) study arm, considered the "intervention group" will receive training on completion of a reverse shoulder arthroplasty using an iVR simulator (PrecisionOS Technology).

Group Type: ACTIVE_COMPARATOR

Immersive Virtual Reality

Intervention Type: OTHER

Participants randomized to the iVR simulator utilizes a head-mounted display producing 3D visuals with haptic controllers for an immersive operating room experience. The module produced consists of the key steps in performing a reverse shoulder arthroplasty using virtual versions of the equipment used in the real procedure. Prior to initiation, participants will be provided with a safety and training demonstration on the use of the VR module by study personnel. Participants will be provided as much time as they require to watch the video, including repetition if desired, which they will be timed for completion.

Surgical Video

Participants randomized to the standard video study arm, considered the "control group" will receive training on completion of reverse shoulder arthroplasty using a technical surgical instructional video.

Group Type: OTHER

Surgical Technical Instructional Video

Intervention Type: OTHER

Participants will be provided as much time as they require to watch the instructional video, including repetition if desired, which they will be timed for completion.
