Augmented Reality Headset Protects Doctors From Coronavirus
One of the largest NHS trusts in England is using Microsoft HoloLens on its Covid-19 wards to keep doctors safe as they help patients with the virus. Staff at Imperial College Healthcare NHS Trust are wearing the mixed-reality headset as they work on the frontline in the most high-risk area of some of London’s busiest hospitals. HoloLens with Dynamics 365 Remote Assist uses Microsoft Teams to send a secure live video-feed to a computer screen in a nearby room, allowing healthcare teams to see everything the doctor treating Covid-19 patients can see, while remaining at a safe distance.
Imperial College Healthcare NHS Trust, which includes Charing Cross Hospital, Hammersmith Hospital and St Mary’s Hospital, says using HoloLens has led to a fall in the amount of time staff are spending in high-risk areas of up to 83%. It is also significantly reducing the amount of personal protective equipment (PPE) being used, as only the doctor wearing the headset has to dress in PPE. Early estimates that using HoloLens is saving up to 700 items of PPE per ward, per week.
“In March, we had a hospital full of Covid-19 patients. Doctors, nurses and allied healthcare professionals providing ward care had a high risk of exposure to the virus and many became ill. Protecting staff was a major motivating factor for this work, but so was protecting patients. If our staff are ill they can transmit disease and they are unable to provide expert medical care to those who needed it most, said James Kinross, a consultant surgeon at Imperial College Healthcare? Kinross has been using HoloLens for many years at the hospital. “In one week our hospital trust switched from being a place that delivered acute, elective care and planned treatment into a giant intensive care unit. We weren’t just trying to restructure an entire building, we were trying to redeploy and retrain our staff, while at the same time we had to cope with an ever-growing number of very sick people. “We needed an innovative solution. I’ve used HoloLens before in surgery and we quickly realised it had a unique role to play because we could take advantage of its hands-free telemedicine capabilities. Most importantly, it could be used while wearing PPE. It solved a major problem for us during a crisis, by allowing us to keep treating very ill patients while limiting our exposure to a deadly virus. Not only that, it reduced our PPE consumption and significantly improved the efficiency of our ward rounds.”
Rather than put users in a fully computer-generated world, as virtual reality does, HoloLens allows users to place 3D digital models in the room alongside them and interact with them using gestures, gaze and voice.
