This week, the Institute of Medical Information and Management Systems (HIMSS) annual global meeting, Xi Desi - Sinai Medical Center (Cedars-Sinai) health services research director Brennan Spiegel to share some of the results of the use of virtual reality medical aid, and to reduce the The patient can refer to and experience the experience when he is in pain.
The discovery that VR can be used for pain relief stems from chance. In 1993, VR pioneer Tom Furness launched a consumer eyewear that was not selling well, but many dentists bought it to distract the patient. The discovery led to more research, but ultimately limited by cost—early VR medical devices cost $35,000, far more expensive than today's consumer VR glasses.
Cedars-Sinai Hospital is the first hospital to use VR technology. Located in Los Angeles, it is one of the largest non-profit academic medical centers in the United States. Cedars-Sinai Hospital invested in Applied VR through the TechStars Medical Accelerator and co-developed a line of products called Pain RelieVR (Pain Relief) to help patients ease the pain of treatment or rehabilitation.
The hospital used Samsung Gear VR and provided about 25 VR demos. By distracting patients, especially children, these VR applications can alleviate their anxiety and reduce the dose of painkillers. This helps reduce addiction.
“We have worked well with more than 300 patients and gained a lot of experience when it worked and when it was futile,†Spiegel said.
Cedars-Sinai does not have large-scale efficacy data. They are currently conducting a large random experiment comparing VR videos and regular 2D videos of the same content, and it takes 6-8 months to get results. However, in a small controlled study, VR was able to reduce the patient's average pain score from 5.4 to 4.1, and the control group only to 4.8.
At the meeting, Spiegel also shared some areas for improvement. For example, older patients are more likely to refuse to use this method, although once they are used, the experience they experience is deeper than that of younger users. For example, people with stroke, paralysis, epilepsy, nausea, and weakness can't wear slightly cumbersome glasses. In addition, care must be taken in this immersive environment to trigger traumatic memory in patients with PTSD (post-traumatic stress disorder).
