Using a motion-tracking headset to objectively assess surgical performance - A transition to the operating theatre

The HoloLens 2 augmented reality device is one that has the capabilities to track hand movements. The headset has in-built sensors that are able to track the movements of surgeons. There are specific patterns of movement that are associated with increased expertise. The project will involve surgical registrars and consultants performing operations as they normally would whilst wearing the motion-tracking headset. A transition to the operating theatre will allow us to further identify whether this headset can be used in a clinical environment and continue to provide objective assessment data. We aim to video tape the procedures to allow for further post-hoc analysis of the footage. The study will involve the use of the HoloLens 2 in the operating room during operations not involving the use of surgical loupes including open inguinal hernia repairs, orchidopexies, hydrocele repairs, circumcisions and others. All surgeons will have comp[eted a 1 hour session using the headset while performing a simulated surgery. This will allow for acclimatisation for the surgeon and allow for the research team to answer any questions for the surgeon. The surgeons, if consent is provided by both the surgeon and patient, will wear the headset during the appropriate procedure until the target number has been reached. The frequency that a surgeon will use the headset during surgery will depend on their surgical schedule and patient consent. Prior to the procedure, the operating surgeon will have an opportunity to get accustomed to the headset. During the procedure, the operating surgeon will be wearing the HoloLens 2, which will be tracking their hand movements with a focus on path length, total time, and speed of movement to provide an overall gauge of proficiency. A camera that is mounted on the HoloLens will be used to capture video only footage. This will be de-identified and will be from the surgeons point-of-view and will largely capture their hand movements and the operative field. Upon analysis of the data, the research team will access the device's analytic report which will provide an insight into the quality of the data that has been obtained and to monitor for any technical issues that arise.
