Public health crises often disproportionately impact rural America. Sally L. Hodder, M.D., works to alleviate these disparities, especially regarding the opioid crisis and the COVID-19 pandemic. She’s the director of the West Virginia Clinical and Translational Science Institute (WVCTSI), the associate vice president of clinical and translational research, and a professor of medicine at West Virginia University.

Dr. Hodder’s work is focused in West Virginia, but her results are valuable assets to researchers across the country. Not only does treating chronic diseases in rural populations contribute to the overall understanding of those diseases, but engaging with and involving people in those communities in research makes science more accessible to them. Dr. Hodder says, “When folks participate in the science, when there is good community discussion about the trial designs and the results, then I think those populations may be more trusting of the results.”

The United States is in the midst of an opioid overdose epidemic. The rates of opioid addiction, babies born addicted to opioids, and overdoses have skyrocketed in the past decade. No population has been hit harder than rural communities. Many of these communities are in states with historically low levels of funding from the National Institutes of Health (NIH). NIGMS’ Institutional Development Award (IDeA) program builds research capacities in these states by supporting basic, clinical, and translational research, as well as faculty development and infrastructure improvements. IDeA-funded programs in many states have begun prioritizing research focused on reducing the burden of opioid addiction. Below is a snapshot of three of these programs, and how they are working to help their communities:

Vermont Center on Behavior and Health

Because there are generally fewer treatment resources in rural areas compared to larger cities, it can take longer for people addicted to opioids in rural settings to get the care they need. The Vermont Center on Behavior and Health works to address this need and its major implications.

“One very disconcerting trend we’re seeing with this recent crisis is that opioid-addicted individuals are being placed on wait lists lasting months to a year without any kind of treatment,” says Vermont Center on Behavior and Health director Stephen Higgins. “And it’s very unlikely that anyone who is opioid addicted is just going to abstain while they are on a wait list.”

In urban areas, buprenorphine—an approved medication for opioid addiction that can prevent or reduce withdrawal symptoms—is generally dispensed by trained physicians at treatment clinics. Unfortunately, many rural communities don’t have enough physicians and clinics to serve patients in need. While waiting for treatment, patients are at risk of premature death, overdose, and contracting diseases such as HIV.

Stacey Sigmon, a faculty member in the Vermont Center on Behavior Health, has developed a method to help tackle this problem: a modified version of a tamper-proof device that delivers daily doses of buprenorphine. The advantage of using the modified device is that it makes each day’s dose available during a preprogrammed 3-hour window within the patient’s home, eliminating the need to visit a clinic.

During a study, participants in the treatment group received interim buprenorphine from the device. They also received daily calls to assess drug use, craving, and withdrawal. Participants in the control group didn’t receive buprenorphine. They remained on the waiting list of their local clinic and didn’t receive phone calls. The results, published in the New England Journal of Medicine (NEJM), indicate that the device works. Participants who received the interim buprenorphine treatment submitted a higher percentage of drug test specimens that were negative for opioids than those in the control group at 4 weeks (88 percent vs. 0 percent), 8 weeks (84 percent vs. 0 percent), and 12 weeks (68 percent vs. 0 percent). Sigmon and colleagues are currently testing the device with a much larger group of participants.

“This tool is now available to other rural states that are also being devastated by this crisis and are not so far along in beefing up treatment capacity,” says Higgins.

Taking the Guesswork Out of Pain Management

by Barbara Vann

How do you measure pain? A patient’s furrowed brow, a child’s cries or tears—all are signs of pain. But what if the patient suffers from severe dementia and can’t describe what she is feeling or is a young child who can’t yet talk? Caregivers can help read the signs of pain, but their interpretations may differ greatly from patient to patient, because people have different ways of showing discomfort. And when the patient is unconscious, such as during surgery or while in intensive care, the caregiving team has even fewer ways to measure pain.

Assessing pain is an inexact science. It includes both subjective and objective measures. A patient might be asked during a subjective assessment (performed, perhaps, with a caregiver showing a pain-rating scale such as the one in the figure), “How much pain are you feeling today?” That feedback is coupled with biological markers such as an increased heart rate, dilated pupils, sweating, and inflammation as well as blood tests to monitor high levels of the stress hormone cortisol. Combined, these measurements can give doctors a fairly clear picture of how much pain a patient feels.

But imagine if members of the surgical or caregiving team could actually “see” how the patient is feeling? Such insight would let them select better drugs to use during and after surgery, tailoring care to each patient. That tool could be put into service in the operating room and by the bedside in intensive care, giving nonstop reports of pain as the patient experiences it.

An objective measure of pain also has uses beyond the operating room and intensive care unit. Given the high risk for opioid misuse, such a measure could take the guesswork out of pain management and give doctors a more accurate indication of pain levels to prevent over-prescribing opioid pain relievers.

A World Without Pain

In an immersive virtual reality environment called “Snow World,” burn patients distract themselves from their pain by tossing snow balls, building snowmen and interacting with penguins. Credit: Ari Hollander and Howard Rose, copyright Hunter Hoffman, UW, www.vrpain.com

You glide across an icy canyon where you meet smiling snowmen, waddling penguins and a glistening river that winds forever. You toss snowballs, hear them smash against igloos, then watch them explode in vibrant colors.

Back in the real world, a dentist digs around your mouth to remove an impacted tooth, a procedure that really, really hurts. Could experiencing a “virtual” world distract you from the pain? NIGMS grantees David Patterson and Hunter Hoffman show it can.

Patterson, a psychologist at the University of Washington (UW) in Seattle, and Hoffman, a UW cognitive psychologist, helped create the virtual reality program “Snow World” in an effort to reduce excessive pain experienced by burn patients. However, the researchers expect Snow World to help alleviate all kinds of pain, including pain experienced during dental procedures. Continue reading “A World Without Pain”

The pain stemming from second- and third-degree burns is among the worst known. Throughout recovery, the intense, disabling pain patients feel can lead to sleeplessness, anxiety and depression.

David Patterson first entered a burn ward as a psychologist hoping to help patients cope with these issues. He saw patients refuse wound cleaning because of how painful it could be.

“I’ve learned how horribly difficult it is to control burn and trauma pain with medications alone,” he says. “The amount of pain people feel affects how well they adjust in the long term.” Pain and the mental, social and emotional problems it causes also hinder the body’s ability to heal physically.

Today, Patterson is committed to helping burn patients overcome pain, allowing their bodies—as well as their minds—to heal more efficiently. Using virtual reality (VR) technology, Patterson has found an effective complement to pain-relieving drugs such as morphine and other opioid analgesics.

Patterson’s Findings

“To be honest, for acute pain, you give someone a shot or a pill and it’s instant relief,” Patterson says. But opioid analgesics carry problems. Sometimes patients don’t respond well to morphine or require high dosages that carry strong side effects.

When burn patients undergo routine wound care, the pain can be excruciating—as bad as or worse than the original burn incident. Realizing the brain can take only so many stimuli, Patterson collaborated with fellow UW psychologist Hunter Hoffman to experiment with VR in pain relief. When combined with minimal pain medications, VR is a powerful solution to acute pain. By providing a computer-generated reality—for example, an icy canyon filled with snowmen and Paul Simon’s music, as in the case of their creation SnowWorld—the patient’s eyes, ears and mind are so occupied that he or she can effectively ignore the pain.

Patterson and his team found that VR pain reduction strategies are as powerful as opioid analgesics, without the negative side effects. The technology doesn’t require specialized expertise and is getting progressively less expensive, making it economically attractive. At least eight hospitals have adopted the methods as part of their clinical program, allowing Patterson an opportunity to conduct further studies on the long-term effects of using these complementary methods and the efficacy of the techniques on other kinds of pain.
