About this study

This study investigates the effectiveness of using Hololens2 for remote education and feedback in medical procedures, specifically central venous catheterization. HoloLens-based education offers realistic simulation and real-time feedback, enhancing learners' skills and providing a safe practice environment. This approach is expected to improve the efficacy of central venous catheter training and enhance healthcare professionals' abilities, thereby ensuring greater patient safety. The research aims to explore whether medical professionals can correctly perform procedures with remote guidance and feedback through Hololens2 and examines the potential of Head-Mounted Displays (HMDs) in medical education and their practical application in clinical settings.

Read the detailed description

This study is a Randomized Controlled Trial (RCT) comparing two groups regarding the supervision method in medical training:

  1. Face-to-Face Supervised Group: This group receives supervision in person.
  2. HoloLens 2 Supervised Group: Participants in this group receive supervision through content provided on HoloLens 2.

Medical professionals enrolled in the study will receive training in a specific surgical technique (C-line) using both supervision methods, with the order of training being randomly assigned. The study aims to investigate the validity of this training method. As part of the study, a brief survey will be conducted during the consent process.

The researchers will measure the total time taken for the training and the time taken for each step of the surgical technique. They will also use a standard Checklist to score the proficiency in performing the C-line technique. Additionally, the number of times the participants request assistance from the research supervisor will be recorded.

After the supervision, the effectiveness of each method will be assessed through survey questions. These questions will be administered both before and after the training (Pre-Post) to facilitate comparison.

Participants using HoloLens 2 will also undergo an interview about their experience using this technology, aiming to gather feedback on HoloLens 2.

Two weeks after the training, the clinical participants will perform the surgical technique again to assess their recall of the procedure. This performance will be evaluated using the Checklist.

All training sessions will be recorded on video, focusing on the hands and the model used for the surgical technique, without capturing identifiable facial features. These recordings will be used for timekeeping and analysis purposes and will be disposed of after the research concludes.

Being tested
Hololens2(Microsoft), Face-to-face supervision

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Hololens2(Microsoft)Device

    Using Hololens as a Remote-teaching tool when supervising

  • Face-to-face supervisionBehavioural

    Participants performed central venous catheterization on an ultrasound-compatible simulation model under conventional in-person supervision. A supervising physician was physically present to provide real-time verbal feedback and direct intervention, and a procedural manual was displayed on a laptop.

Study groups in NCT07861555
Study groupRoleWhat they receive
Test groupExperimentalSupervision for participants in this group is provided through content delivered on intervention using HoloLens 2, a virtual reality technology. The aim is to compare the effectiveness of VR-assisted learning with traditional face-to-face training methods. Key measures include the time taken for training, proficiency in the surgical technique as per a standard Checklist, and the number of times participants seek assistance. An important component of this group's experience is the interview regarding their experience using HoloLens 2, aiming to gather feedback on the VR technology. The group's performance in recalling and executing the surgical technique after a two-week period is also assessed.
Receives: Device: Hololens2(Microsoft)
Control groupActive comparatorParticipants in this group receive supervision in person, which involves direct interaction with a supervisor during the training. The focus of this group is to assess the effectiveness of traditional face-to-face training methods in imparting skills related to a specific surgical technique (C-line). The training includes direct feedback, guidance, and real-time supervision from the trainer. The efficiency of learning, time taken to master the technique, and the proficiency achieved are key aspects being measured. Additional observations include the frequency of requests for assistance from the supervisor and the retention of the learned skills over a period of time.
Receives: Behavioral: Face-to-face supervision

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Differences between Test and Control Group on the C-line procedure scores of pre and post test

    The primary outcome of the study is the comparison of surgical technique checklist scores, as evaluated by the researchers and supervisors, between the pre-test and post-test for each group. This involves assessing the proficiency and skill development in the surgical procedure before and after the training, using a standardized checklist.

    Measured: pre test and 2 week post test
