VR Gives Oregon Patients And Doctors An Alternative To Opioids

Oregon’s largest health care providers see both promise and challenges in virtual reality as a non-opioid treatment for pain.

For Moira Reeves, what helps keep the pain at bay is “Bear Blast.”

In her virtual reality (VR) world, the 6-year-old from Baker City, Oregon, is roaming a cartoonish Wild West town, blasting dodgeballs at teddy bears that pop up from the ground.

In the physical world, however, Moira is getting her wound dressing changed. The VR experience is effectively blocking the presence of the surgical scissors that has become her constant source of anxiety.

Moira has been a patient at the Legacy Oregon Burn Center in Portland for more than two months. On Jan. 20, 2018, she was helping her brother put wood in the fireplace when her dress caught fire.

“Her daddy was able to yank it off before it burned all of her, thank goodness,” said Moira’s grandmother, Beth Fusilier, who flew from Houston, Texas, to be by her granddaughter’s side.

The damage, however, was done. Within moments the ignited dress inflicted second-degree burns on more than 30 percent of Moira’s body.

In early March, once Moira was able to keep herself upright, staff at the Oregon Burn Center turned to VR to help her with the excruciating ritual of burn wound treatment.

“It just made everything a little bit easier,” said Moira’s nurse, Matt Lindsey.

“Generally, before the VR, we would have to give some extra pain medicine partway through the dressing change. And once we started with the VR we didn’t have to do that. We’d just give her pain medicine at the beginning and she was good through the whole thing.”

Hijacking The Brain — In A Good Way

The Oregon Burn Center at Legacy Health was an early adopter of virtual reality pain treatment. In 2011, it tested and purchased VR units to assist patients with the agonizing process of burn wound care, as well as reducing opioid dosage in general.

The steady toll exacted by the opioid abuse epidemic since then has only made decreasing the use of pain pills a more critical imperative.

Data from 2015 show that health providers in the Portland tri-county region wrote nearly as many opioid prescriptions as there were residents: more than 1.4 million for a population of approximately 1.7 million.

Oregon’s health care system has since leveled off that volume of opioid supply, but the demand remains high. This leaves doctors scrambling to find other, non-addictive alternatives to treat patients’ pain.

Virtual reality looks to be that non-pharmacological painkiller in fashion.

There’s been about 30 years of research behind the science of VR for pain. Proponents assert that immersing someone in a 3-D computer-generated world decreases pain perception by diverting the brain’s attention away from its pain signal-processing regions.

A 2007 functional MRI study corroborated this. Brain scans of nine test subjects showed that VR effectively shut off certain areas of the brain that process pain. To be clear, the scans also demonstrated that it was the combined use of VR and opioids that gave the most reduction in pain.

A Dose Of Virtual Otters

An increasing number of hospitals are looking to add to the literature on virtual reality therapy and to test it in real medical settings. A recent such test was performed by Providence Health and Services — Oregon’s largest healthcare provider — out of its Cancer Center in Portland.

The principal investigator, Dr. Shorin Nemeth, said this was Providence’s first VR trial in the in-patient setting and one of the largest such studies to date by sample size.

“Here’s a device that we can test with minimal risk,” Nemeth said. “It’s something that could be, within the next year or two, easily accessible to most consumers. And we want to see if there’s some value in the use of this.”

The testing ran from June to November 2017, with the help of 29 participating cancer patients all recovering from painful abdominal surgeries.

Seattle- and San Francisco-based Firsthand Technology was contracted to provide the VR experiences. In one called “Cool!,” patients gently float along a river and, using hand controllers, throw trout at otters to make them hop and turn rainbow colors.

In another called “Glow,” patients use their hands to gather fireflies and launch animal-shaped lanterns across a moonlit sky.

The “gamified” mechanics, Firsthand CEO Howard Rose asserts, are a big part of what makes the company’s VR content effective: “The design of these experiences is very involved, highly intentional and based on years of experience building pain applications.”

Incorporating motor aspects to virtual reality, on top of sensorial immersion through the headset, seems to occupy more of the brain’s bandwidth to process pain. This falls in line with the Providence trial’s initial findings.

“We have preliminary results — again, I stress the results are preliminary — but they do seem to echo the other studies out there,” said Nemeth, who is also Medical Director of Palliative Services at Providence. By that, he means up to a 30 percent reduction in pain and about a 20 percent reduction in opioid dosing among the 29 trial patients. An analytics team from the Earl A. Chiles Research Institute at Providence Cancer Center is still working on the trial’s raw data. The results will likely be published in late 2018.

Pain Points

Despite VR’s promise, doctors think wide-scale adoption of virtual reality therapy as routine treatment by health systems can’t happen without new models of funding.

“It’s a harsh way to put this, but we really have to look at the financial implications of these technologies,” Nemeth said. “If there’s no money behind it, then the technology is probably going to fall off to the wayside and people are going to seek out this technology on their own. We would like to help guide them through this and use this as a tool that integrates with comprehensive pain care.”

Another hurdle, according to Nemeth, is the process of reclassifying VR specifically as a medical intervention rather than as an entertainment device: “If it’s deemed as a medical device, then it has to go to the FDA for approval. And that process takes a lot of money as well as a lot of time.”

For now, however, Providence Health and Services remains optimistic that medical virtual reality is here to stay.

At a recent “Cool!” and “Glow” demo held at Providence Gresham Rehab and Sports Therapy Clinic, Firsthand Technology CEO Howard Rose shared with the attending physical therapists a more recent VR study involving chronic pain patients.

“Sixty to 70 percent of reductions in pain during the VR,” he said. “And then what’s exciting is after they take the headset off, that persists. And so, two hours to sometimes a day or more later people are feeling the benefit of it.”

The room’s attention was his.

For medical professionals, VR’s journey toward mainstream treatment might take a long time.

Young Moira Reeves’ road to healing, however, is in good stride. As of this story’s publication, she’s due for release from the Oregon Burn Center on April 4, 2018.

About This Series: OPB is participating in a special reporting series, “Opioid Crisis: The Ripple Effect,” that takes an in-depth look at how the national opioid crisis is affecting individuals, families, communities and institutions in the Northwest.

This series is part of a public media collaborative funded by the Corporation for Public Broadcasting (CPB). This national initiative includes reporting from ideastream in the greater Cleveland area and WXXI in Rochester, New York, who, like OPB, explore how their local communities are affected by the crisis.
