NIH HEAL Initiative Meets People Where They Are
Posted on by Rebecca Baker, Ph.D., NIH Helping to End Addiction Long-term® (HEAL) Initiative
The opioid crisis continues to devastate communities across America. Dangerous synthetic opioids, like fentanyl, have flooded the illicit drug supply with terrible consequences. Tragically, based on our most-recent data, about 108,000 people in the U.S. die per year from overdoses of opioids or stimulants [1]. Although this complex public health challenge started from our inability to treat pain effectively, chronic pain remains a life-altering problem for 50 million Americans.
To match the size and complexity of the crisis, in 2018 NIH developed the NIH Helping to End Addiction Long-term® (HEAL) Initiative, an aggressive effort involving nearly all of its 27 institutes and centers. Through more than 1,000 research projects, including basic science, clinical testing of new and repurposed drugs, research with communities, and health equity research, HEAL is dedicated to building a new future built on hope.
In this future:
- A predictive tool used during a health visit personalizes treatment for back pain. The tool estimates the probability that a person will benefit from physical therapy, psychotherapy, or surgery.
- Visits to community health clinics and emergency departments serve as routine opportunities to prevent and treat opioid addiction.
- Qualified school staff and pediatricians screen all children for behavioral and other mental health conditions that increase risk for harmful developmental outcomes, including opioid misuse.
- Infants born exposed to opioids during a mother’s pregnancy receive high-quality care—setting them up for a healthy future.
Five years after getting started (and interrupted by a global pandemic), HEAL research is making progress toward achieving this vision. I’ll highlight three ways in which scientific solutions are meeting people where they are today.
A Window of Opportunity for Treatment in the Justice System
Sadly, jails and prisons are “ground zero” for the nation’s opioid crisis. Eighty-five percent of people who are incarcerated have a substance use disorder or a history of substance use. Our vision at HEAL is that every person in jail, prison, or a court-supervised program receives medical care, which includes effective opioid use disorder treatment.
Some research results already are in supporting this approach: A recent HEAL study learned that individuals who had received addiction treatment while in one Massachusetts jail were about 30 percent less likely to be arrested, arraigned, or incarcerated again compared with those incarcerated during the same time period in a neighboring jail that did not offer treatment [2]. Research from the HEAL-supported Justice Community Opioid Innovation Network also is exploring public perceptions about opioid addiction. One such survey showed that most U.S. adults see opioid use disorder as a treatable medical condition rather than as a criminal matter [3]. That’s hopeful news for the future.
A Personalized Treatment Plan for Chronic Back Pain
Half of American adults live with chronic back pain, a major contributor to opioid use. The HEAL-supported Back Pain Consortium (BACPAC) is creating a whole-system model for comprehensive testing of everything that contributes to chronic low back pain, from anxiety to tissue damage. It also includes comprehensive testing of promising pain-management approaches, including psychotherapy, antidepressants, or surgery.
Refining this whole-system model, which is nearing completion, includes finding computer-friendly ways to describe the relationship between the different elements of pain and treatment. That might include developing mathematical equations that describe the physical movements and connections of the vertebrae, discs, and tendons.
Or it might include an artificial intelligence technique called machine learning, in which a computer looks for patterns in existing data, such as electronic health records or medical images. In keeping with HEAL’s all-hands-on-deck approach, BACPAC also conducts clinical trials to test new (or repurposed) treatments and develop new technologies focused on back pain, like a “wearable muscle” to help support the back.
Harnessing Innovation from the Private Sector
The HEAL research portfolio spans basic science to health services research. That allows us to put many shots on goal that will need to be commercialized to help people. Through its research support of small businesses, HEAL funding offers a make-or-break opportunity to advance a great idea to the marketplace, providing a bridge to venture capital or other larger funding sources needed for commercialization.
This bridge also allows HEAL to invest directly in the heart of innovation. Currently, HEAL funds nearly 100 such companies across 20 states. While this is a relatively small portion of all HEAL research, it is science that will make a difference in our communities, and these researchers are passionate about what they do to build a better future.
A couple of current examples of this research passion include: delivery of controlled amounts of non-opioid pain medications after surgery using a naturally absorbable film or a bone glue; immersive virtual reality to help people with opioid use disorder visualize the consequences of certain personal choices; and mobile apps that support recovery, taking medications, or sensing an overdose.
In 2023, HEAL is making headway toward its mission to accelerate development of safe, non-addictive, and effective strategies to prevent and treat pain, opioid misuse, and overdose. We have 314 clinical trials underway and 41 submissions to the Food and Drug Administration to begin clinical testing of investigational new drugs or devices: That number has doubled in the last year. More than 100 projects alone are addressing back pain, and more than 200 projects are studying medications for opioid use disorder.
The nation’s opioid crisis is profoundly difficult and multifaceted—and it won’t be solved with any single approach. Our research is laser-focused on its vision of ending addiction long-term, including improving pain management and expanding access to underused, but highly effective, addiction medications. Every day, we imagine a better future for people with physical and emotional pain and communities that are hurting. Hundreds of researchers and community members across the country are working to achieve a future where people and communities have the tools they need to thrive.

A Whole Person Approach to Lifting the Burden of Chronic Pain Among Service Members and Veterans
Posted on by Helene M. Langevin, M.D., National Center for Complementary and Integrative Health
Chronic pain and its companion crisis of opioid misuse have taken a terrible toll on Americans. But the impact has been even greater on U.S. service members and veterans, who often deal with the compounded factors of service-related injuries and traumatic stress.
For example, among soldiers in a leading U.S. Army unit, 44 percent had chronic pain and 15 percent used opioids after a combat deployment. That compares to 26 percent and 4 percent, respectively, in the general population [1,2].
This disproportionate burden of chronic pain among veterans [3] and service members led NIH’s National Center for Complementary and Integrative Health (NCCIH) to act. We forged a collaboration in 2017 across NIH, U.S. Department of Defense (DOD), and U.S. Department of Veteran’s Affairs (VA) to establish the Pain Management Collaboratory (PMC).
The PMC’s research focusing on the implementation and evaluation of nondrug approaches for the management of pain is urgently needed in the military and across our entire country. Nondrug approaches require a shift in thinking. Rather than focusing solely on blocking pain temporarily using analgesics, nondrug approaches work with the mind and body to promote the resolution of chronic pain and the long-term restoration of health through techniques and practices such as manual therapy, yoga, and mindfulness-based interventions.
Addressing chronic pain in ways that don’t only rely on drugs means addressing underlying issues, such as joints and connective tissue that lack adequate movement or training our brains to “turn down the volume” on pain signals. Using mind and body practices to reduce pain can help promote health in other ways. Possible “fringe benefits” include better sleep, more energy for physical activity, a better mindset for making good nutritional choices, and/or improved mood.
Indeed, there is a growing body of research on the benefits of nondrug approaches to address chronic pain. What is so powerful about PMC is it puts this knowledge to work by embedding research within military health care settings.
The PMC supports a shared resource center and 11 large-scale pragmatic clinical trials. Within this real-world health care setting, the clinical trials have enrolled more than 8,200 participants across 42 veteran and military health systems. These studies offer both strength in numbers and insights into what happens when learnings from controlled clinical trials collide with the realities of health care delivery and the complexities of daily life. [4]
Central to the PMC partnership is whole person health. Too often, we see health through the prism of separate parts—for example, a person’s cardiovascular, digestive, and mental health problems are viewed as co-occurring rather than as interrelated conditions. A whole person framework—a central focus of NCCIH’s current Strategic Plan—brings the parts back together and recognizes that health exists across multiple interconnected body systems and domains: biological, behavioral, social, and environmental.
The VA’s implementation of a whole health model [5] and their unique closed-loop health care system offers an opportunity to deliver care, conduct research, and illustrate what happens when people receive coordinated care that treats the whole person. In fact, VA’s leadership in this area was the impetus for a recent report by the National Academies of Sciences, Engineering, and Medicine. The report underscored the importance of implementing whole person health care in all settings and for every American.
There are many opportunities ahead for this interagency collaboration. It will help to achieve an important shift, from treating problems one at a time to promoting overall military readiness, resilience, and well-being for U.S. service members and veterans.
Congress appropriated $5 million to NCCIH in fiscal year 2023 to enhance pain research with a special emphasis on military populations. These additional resources will allow NCCIH to support more complex studies in understanding how multiple therapeutic approaches that impact multiple body systems can impact chronic pain.
Meanwhile, programs like the DOD’s Consortium for Health and Military Performance (CHAMP) will continue to translate these lessons learned into accessible pain management information that service members can use in promoting and maintaining their health.
While the PMC’s research program specifically targets the military community, this growing body of knowledge will benefit us all. Understanding how to better manage chronic pain and offering more treatment options for those who want to avoid the risks of opioids will help us all build resilience and restore health of the whole person.

Understanding Long-Term COVID-19 Symptoms and Enhancing Recovery
Posted on by Walter J. Koroshetz, M.D., National Institute of Neurological Disorders and Stroke
We are in the third year of the COVID-19 pandemic, and across the world, most restrictions have lifted, and society is trying to get back to “normal.” But for many people—potentially millions globally—there is no getting back to normal just yet.
They are still living with the long-term effects of a COVID-19 infection, known as the post-acute sequelae of SARS-CoV-2 infection (PASC), including Long COVID. These people continue to experience debilitating fatigue, shortness of breath, pain, difficulty sleeping, racing heart rate, exercise intolerance, gastrointestinal and other symptoms, as well as cognitive problems that make it difficult to perform at work or school.
This is a public health issue that is in desperate need of answers. Research is essential to address the many puzzling aspects of Long COVID and guide us to effective responses that protect the nation’s long-term health.
For the past two years, NIH’s National Heart, Lung, and Blood Institute (NHLBI), the National Institute of Allergy and Infectious Diseases (NIAID), and my National Institute of Neurological Disorders and Stroke (NINDS) along with several other NIH institutes and the office of the NIH Director, have been leading NIH’s Researching COVID to Enhance Recovery (RECOVER) initiative, a national research program to understand PASC.
The initiative studies core questions such as why COVID-19 infections can have lingering effects, why new symptoms may develop, and what is the impact of SARS-CoV-2, the virus that causes COVID-19, on other diseases and conditions? Answering these fundamental questions will help to determine the underlying biologic basis of Long COVID. The answers will also help to tell us who is at risk for Long COVID and identify therapies to prevent or treat the condition.
The RECOVER initiative’s wide scope of research is also unprecedented. It is needed because Long COVID is so complex, and history indicates that similar post infectious conditions have defied definitive explanation or effective treatment. Indeed, those experiencing Long COVID report varying symptoms, making it highly unlikely that a single therapy will work for everyone, underscoring the need to pursue multiple therapeutic strategies.
To understand Long COVID fully, hundreds of RECOVER investigators are recruiting more than 17,000 adults (including pregnant people) and more than 18,000 children to take part in cohort studies. Hundreds of enrolling sites have been set up across the country. An autopsy research cohort will also provide further insight into how COVID-19 affects the body’s organs and tissues.
In addition, researchers will analyze electronic health records from millions of people to understand how Long COVID and its symptoms change over time. The RECOVER initiative is also utilizing consistent research protocols across all the study sites. The protocols have been carefully developed with input from patients and advocates, and they are designed to allow for consistent data collection, improve data sharing, and help to accelerate the pace of research.
From the very beginning, people suffering from Long COVID have been our partners in RECOVER. Patients and advocates have contributed important perspectives and provided valuable input into the master protocols and research plans.
Now, with RECOVER underway, individuals with Long COVID, their caregivers, and community members continue to serve a critical role in the Initiative. The National Community Engagement Group (NCEG) has been established to make certain that RECOVER meets the needs of all people affected by Long COVID. The RECOVER Patient and Community Engagement Strategy outlines all the approaches that RECOVER is using to engage with and gather input from individuals impacted by Long COVID.
The NIH recently made more than 40 awards to improve understanding of the underlying biology and pathology of Long COVID. There have already been several important findings published by RECOVER scientists.
For example, in a recent study published in the journal Lancet Digital Health, RECOVER investigators used machine learning to comb through electronic health records to look for signals that may predict whether someone has Long COVID [1]. As new findings, tools, and technologies continue to emerge that help advance our knowledge of the condition, the RECOVER Research Review (R3) Seminar Series will provide a forum for researchers and our partners with up-to-date information about Long COVID research.
It is important to note that post-viral conditions are not a new concept. Many, but not all, of the symptoms reported in Long COVID, including fatigue, post-exertional malaise, chronic musculoskeletal pain, sleep disorders, postural orthostatic tachycardia (POTS), and cognitive issues, overlap with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS).
ME/CFS is a serious disease that can occur following infection and make people profoundly sick for decades. Like Long COVID, ME/CFS is a heterogenous condition that does not affect everybody in the same way, and the knowledge gained through research on Long COVID may also positively impact the understanding, treatment, and prevention of POTS, ME/CFS, and other chronic diseases.
Unlike other post-viral conditions, people who experience Long COVID were all infected by the same virus—albeit different variants—at a similar point in time. This creates a unique opportunity for RECOVER researchers to study post-viral conditions in real-time.
The opportunity enables scientists to study many people simultaneously while they are still infected to monitor their progress and recovery, and to try to understand why some individuals develop ongoing symptoms. A better understanding of the transition from acute to chronic disease may offer an opportunity to intervene, identify who is at risk of the transition, and develop therapies for people who experience symptoms long after the acute infection has resolved.
The RECOVER initiative will soon announce clinical trials, leveraging data from clinicians and patients in which symptom clusters were identified and can be targeted by various interventions. These trials will investigate therapies that are indicated for other non-COVID conditions and novel treatments for Long COVID.
Through extensive collaboration across the multiple NIH institutes and offices that contribute to the RECOVER effort, our hope is critical answers will emerge soon. These answers will help us to recognize the full range of outcomes and needs resulting from PASC and, most important, enable many people to make a full recovery from COVID-19. We are indebted to the over 10,000 subjects who have already enrolled in RECOVER. Their contributions and the hard work of the RECOVER investigators offer hope for the future to the millions still suffering from the pandemic.

Tackling Complex Scientific Questions Requires a Team Approach
Posted on by Nora D. Volkow, M.D., National Institute on Drug Abuse
During the COVID-19 pandemic, we have seen unprecedented, rapid scientific collaboration, as experts around the world in discrete, previously disconnected fields, have found ways to collaborate to face a common cause. For example, physicists helped respiratory specialists understand how virus particles could spread in air, leading to improved mitigation strategies. Specialists in cardiovascular science, neuroscience, immunology, and other fields are now working together to understand and address Long COVID. Over the past two years, we have also seen remarkable international sharing of epidemiological data and information on effects of vaccines.
Science is increasingly a team activity, which is true for many fields, not just biomedicine. The professional diversity of research teams reflects the increased complexity of the questions science is called upon to answer. This is especially obvious in the study of the brain, which is the most complex system known to us.
The NIH’s Brain Research Through Advancing Innovative Neurotechnologies® (BRAIN) Initiative, with the goal of vastly enhancing neuroscience through new technologies, includes research teams with neuroscientists, engineers, mathematicians, physicists, data scientists, ethicists, and more. Nearly half (47 percent) of grant awards have multiple principal investigators.
Besides the BRAIN Initiative, other multi-institute NIH research projects are applying team science to complex research questions, such as those related to neurodevelopment, addiction, and pain. The Helping to End Addiction Long-term® Initiative, or NIH HEAL Initiative®, created a team-based research framework to advance promising pain therapeutics quickly to clinical testing.
In the Adolescent Brain Cognitive Development (ABCD) study, which is led by NIDA in close partnership with NIH’s National Institute on Alcohol Abuse and Alcoholism (NIAAA), and other NIH institutes, 21 research centers are collecting behavioral, biospecimen, and neuroimaging data from 11,878 children from age 10 through their teens. Teams led by experts in adolescent psychiatry, developmental psychology, and pediatrics interview participants and their families. These experts then gather a battery of health metrics from psychological, cognitive, sociocultural, and physical assessments, including collection and analysis of various kinds of biospecimens (blood, saliva). Further, experts in biophysics gather information on the structure and function of participants’ brains every two years.
A similar study of young children in the first decade of life beginning with the prenatal period, the HEALthy Brain and Child Development (HBCD) study, supported by HEAL, NIDA, and several other NIH institutes and centers, is now underway at 25 research sites across the country. A range of scientific specialists, similar to that in the ABCD study, is involved in this effort. In this case, they are aided by experts in obstetric care and in infant neuroimaging.
For both of these studies, teams of data scientists validate and curate all the information generated and make it available to researchers across the world. This makes it possible to investigate complex questions such as human neurodevelopmental diversity and the effects of genes and social experiences and their relation to mental health. More than half of the publications using ABCD data have been authored by non-ABCD investigators taking advantage of the open-access format.
Yet, institutions that conduct and fund science—including NIH—have been slow to support and reward collaboration. Because authorship and funding are so important in tenure and promotion decisions at universities, for example, an individual’s contribution to larger, multi-investigator projects on which they may not be the grantee or lead author on a study publication may carry less weight.
For this reason, early-career scientists may be particularly reluctant to collaborate on team projects. Among the recommendations of a 2015 National Academies of Sciences, Engineering, and Medicine (NASEM) report, Enhancing the Effectiveness of Team Science, was that universities and other institutions should find effective ways to give credit for team-based work to assist promotion and tenure committees.
The strongest teams will be diverse in other respects, not just scientific expertise. Besides more actively fostering productive collaborations across disciplines, NIH is making a more concerted effort to promote racial equity and inclusivity in our research workforce, both through the NIH UNITE Initiative and through Institute-specific initiatives like NIDA’s Racial Equity Initiative.
To promote diversity, inclusivity, and accessibility in research, the BRAIN Initiative recently added a requirement in most of its funding opportunity announcements (FOAs) that has applicants include a Plan for Enhancing Diverse Perspectives (PEDP) in the proposed research. The PEDPs are evaluated and scored during the peer review as part of the holistic considerations used to inform funding decisions. These long-overdue measures will not only ensure that NIH-funded science is more diverse, but they are also important steps toward studying and addressing social determinants of health and the health disparities that exist for so many conditions.
Increasingly, scientific discovery is as much about exploring new connections between different kinds of researchers as it is about finding new relationships among different kinds of scientific databases. The challenges before us are great—ending the COVID pandemic, finding a solution to the addiction and overdose crisis, and so many others—and increased collaboration between scientists will give us the greatest chance to successfully overcome these challenges.

Research to Address the Real-Life Challenges of Opioid Crisis
Posted on by Lawrence Tabak, D.D.S., Ph.D.
While great progress has been made in controlling the COVID-19 pandemic, America’s opioid crisis continues to evolve in unexpected ways. The opioid crisis, which worsened during the pandemic and now involves the scourge of fentanyl, claims more than 70,000 lives each year in the United States [1]. But throughout the pandemic, NIH has continued its research efforts to help people with a substance use disorder find the help that they so need. These efforts include helping to find relief for the millions of Americans who live with severe and chronic pain.
Recently, I traveled to Atlanta for the Rx and Illicit Drug Summit 2022. While there, I moderated an evening fireside chat with two of NIH’s leaders in combating the opioid crisis: Nora Volkow, director of the National Institute on Drug Abuse (NIDA); and Rebecca Baker, director of Helping to End Addiction Long-term® (HEAL) initiative. What follows is an edited, condensed transcript of our conversation.
Tabak: Let’s start with Nora. When did the opioid crisis begin, and how has it changed over the years
Volkow: It started just before the year 2000 with the over-prescription of opioid medications. People were becoming addicted to them, many from diverted product. By 2010, CDC developed guidelines that decreased the over-prescription. But then, we saw a surge in heroin use. That turned the opioid crisis into two problems: prescription opioids and heroin.
In 2016, we encountered the worst scourge yet. It is fentanyl, an opioid that’s 50 times more potent than heroin. Fentanyl is easily manufactured, and it’s easier than other opioids to hide and transport across the border. That makes this drug very profitable.
What we have seen during the pandemic is the expansion of fentanyl use in the United States. Initially, fentanyl made its way to the Northeast; now it’s everywhere. Initially, it was used to contaminate heroin; now it’s used to contaminate cocaine, methamphetamine, and, most recently, illicit prescription drugs, such as benzodiazepines and stimulants. With fentanyl contaminating all these drugs, we’re also seeing a steep rise in mortality from cocaine and methamphetamine use in African Americans, American Indians, and Alaska natives.
Tabak: What about teens? A recent study in the journal JAMA reported for the first time in a decade that overdose deaths among U.S. teens rose dramatically in 2020 and kept rising through 2021 [2]. Is fentanyl behind this alarming increase?
Volkow: Yes, and it has us very concerned. The increase also surprised us. Over the past decade, we have seen a consistent decrease in adolescent drug use. In fact, there are some drugs that have the lowest usage rates that we’ve ever recorded. To observe this more than doubling of overdose deaths from fentanyl before the COVID pandemic was a major surprise.
Adolescents don’t typically use heroin, nor do they seek out fentanyl. Our fear is adolescents are misusing illicit prescriptions contaminated with fentanyl. Because an estimated 30-40 percent of those tainted pills contain levels of fentanyl that can kill you, it becomes a game of Russian roulette. This dangerous game is being played by adolescents who may just be experimenting with illicit pills.
Tabak: For people with substance use disorders, there are new ways to get help. In fact, one of the very few positive outcomes of the pandemic is the emergence of telehealth. If we can learn to navigate the various regulatory issues, do you see a place for telehealth going forward?
Volkow: When you have a crisis like this one, there’s a real need to accelerate interventions and innovation like telehealth. It certainly existed before the pandemic, and we knew that telehealth was beneficial for the treatment of substance use disorders. But it was very difficult to get reimbursement, making access extremely limited.
When COVID overwhelmed emergency departments, people with substance use disorders could no longer get help there. Other interventions were needed, and telehealth helped fill the void. It also had the advantage of reaching rural populations in states such as Kentucky, West Virginia, Ohio, where easy access to treatment or unique interventions can be challenging. In many prisons and jails, administrators worried about bringing web-based technologies into their facilities. So, in partnership with the Justice Department, we have created networks that now will enable the entry of telehealth into jails and prisons.
Tabak: Rebecca, it’s been four years since the HEAL initiative was announced at this very summit in 2018. How is the initiative addressing this ever-evolving crisis?
Baker: We’ve launched over 600 research projects across the country at institutions, hospitals, and research centers in a broad range of scientific areas. We’re working to come up with new treatment options for pain and addiction. There’s exciting research underway to address the craving and sleep disruption caused by opioid withdrawal. This research has led to over 20 investigational new drug applications to the FDA. Some are for repurposed drugs, compounds that have already been shown to be safe and effective for treating other health conditions that may also have value for treating addiction. Some are completely novel. We have also initiated the first testing of an opioid vaccine, for oxycodone, to prevent relapse and overdose in high-risk individuals.
Tabak: What about clinical research?
Baker: We’re testing multiple different treatments for both pain and addiction. Not everyone with pain is the same, and not every treatment is going to work the same for everyone. We’re conducting clinical trials in real-world settings to find out what works best for patients. We’re also working to implement lifesaving, evidence-based interventions into places where people seek help, including faith, community, and criminal justice settings.
Tabak: The pandemic highlighted inequities in our health-care system. These inequities afflict individuals and populations who are struggling with addiction and overdose. Nora, what needs to be done to address the social determinants of racial disparities?
Volkow: This is an extraordinarily important question. As you noted, certain racial and ethnic groups had disproportionately higher mortality rates from COVID. We have seen the same with overdose deaths. For example, we know that the most important intervention for preventing overdoses is to initiate medications such as methadone, buprenorphine or vivitrol. But Black Americans are initiated on these medications at least five years later than white Americans. Similarly, Black Americans also are less likely to receive the overdose-reversal medication naloxone.
That’s not right. We must ask what are the core causes of limited access to high-quality health care? Low income is a major contributing factor. Helping people get an education is one of the most important factors to address it. Another factor is distrust of the medical system. When racial and ethnic discrimination is compounded by discrimination because a person has a substance use disorder, you can see why it becomes very difficult for some to seek help. As a society, we certainly need to address racial discrimination. But we also need to address discrimination against substance use disorders in people of all races who are vulnerable.
Baker: Our research is tackling these barriers head on with a direct focus on stigma. As Nora alluded to, oftentimes providers may not offer lifesaving medication to some patients, and we’ve developed and are testing research training to help providers recognize and address their own biases and behaviors in caring for different populations.
We have supported research on the drivers of equity. A big part of this is engaging with people with lived experience and making sure that the interventions being designed are feasible in the real world. Not everyone has access to health insurance, transportation, childcare—the support that they may need to sustain treatment and recovery. In short, our research is seeking ways to enhance linkage to treatment.
Nora mentioned the importance of telehealth in improving equity. That’s another research focus, as well as developing tailored, culturally appropriate interventions for addressing pain and addiction. When you have this trust issue, you can’t always go in with a prescription or a recommendation from a physician. So in American and Alaskan native communities, we’re integrating evidence-based prevention approaches with traditional practices like wellness gatherings, cooking together, use of sage and spirituality, along with community support, and seeing if that encourages and increases the uptake of these prevention approaches in communities that need it so much.
Tabak: The most heartbreaking impact of the opioid crisis has been the infants born dependent on opioids. Rebecca, what’s being done to help the very youngest victims of the opioid crisis born with neonatal opioid withdrawal syndrome, or NOWS?
Baker: Thanks for asking about the infants. Babies with NOWS undergo withdrawal at birth and cry inconsolably, often with extreme stomach upset and sometimes even with seizures. Our research found that hospitals across the country vary greatly in how they treat these babies. Our program, ACT NOW, or Advancing Clinical Trials in Neonatal Opioid Withdrawal, aims to provide concrete guidance for nurses in the NICU treating these infants. One of the studies that we call Eat, Sleep, Console focuses on the abilities of the baby. Our researchers are testing if the ability to eat, sleep, or be consoled increases bonding with the mother and if it reduces time in the hospital, as well as other long-term health outcomes.
In addition to that NOWS program, we’ve also launched the HEALthy Brain and Child Development Study, or HBCD, that seeks to understand the long-term consequences of opioid exposure together with all the other environmental and other factors the baby experiences as they grow up. The hope is that together these studies will inform future prevention and treatment efforts for both mental health and also substance use and addiction.
Tabak: As the surge in heroin use and appearance of fentanyl has taught us, the opioid crisis has ever-changing dynamics. It tells us that we need better prevention strategies. Rebecca, could you share what HEAL is doing about prevention?
Baker: Prevention has always been a core component of the HEAL Initiative in a number of ways. The first is by preventing unnecessary opioid exposures through enhanced and evidence-based pain management. HEAL is supporting research on new small molecules, new devices, new biologic therapeutics that could treat pain and distinct pain conditions without opioids. And we’re also researching and providing guidance for clinicians on strategies for managing pain without medication, including acupuncture and physical therapy. They can often be just as effective and more sustainable.
HEAL is also working to address risky opioid use outside of pain management, especially in high-risk groups. That includes teens and young adults who may be experimenting, people lacking stable housing, patients who are on high-dose opioids for pain management, or they maybe have gone off high-dose opioids but still have them in their possession.
Finally, to prevent overdose we have to give naloxone to the people who need it. The HEALing Communities Study has taken some really innovative approaches to providing naloxone in libraries, on the beach, and places where overdoses are actually happening, not just in medical settings. And I think that will be, in our fight against the overdose crisis, a key tool.
Volkow: Larry, I’d like to add a few words on prevention. There are evidence-based interventions that have been shown to be quite effective for preventing substance use among teenagers and young adults. And yet, they are not implemented. We have evidence-based interventions that work for prevention. We have evidence-based interventions that work for treatment. But we don’t provide the resources for their implementation, nor do we train the personnel that can carry it over.
Science can give us tools, but if we do not partner at the next level for their implementation, those tools do not have the impact they should have. That’s why I always bring up the importance of policy in the implementation phase.
Tabak: Rebecca, the opioid crisis got started with a lack of good options for treating pain. Could you share with us how HEAL’s research efforts are addressing the needs of millions of Americans who experience both chronic pain and opioid use disorder?
Baker: It’s so important to remember people with pain. We can’t let our efforts to combat the opioid crisis make us lose sight of the needs of the millions of Americans with pain. One hundred million Americans experience pain; half of them have severe pain, daily pain, and 20 million have such severe pain that they can’t do things that are important to them in their life, family, job, other activities that bring their life meaning.
HEAL recognizes that these individuals need better options. New non-addictive pain treatments. But as you say, there is a special need for people with a substance use disorder who also have pain. They desperately need new and better options. And so we recently, through the HEAL Initiative, launched a new trials network that couples medication-based treatment for opioid use disorders, so that’s methadone or buprenorphine, with new pain-management strategies such as psychotherapy or yoga in the opioid use disorder treatment setting so that you’re not sending them around to lots of different places. And our hope is that this integrated approach will address some of the fragmented healthcare challenges that often results in poor care for these patients.
My last point would be that some patients need opioids to function. We can’t forget as we make sure that we are limiting risky opioid use that we don’t take away necessary opioids for these patients, and so our future research will incorporate ways of making sure that they receive needed treatment while also preventing them from the risks of opioid use disorder.
Tabak: Rebecca, let me ask you one more question. What do you want the folks here to remember about HEAL?
Baker: HEAL stands for Helping to End Addiction Long-term, and nobody knows more than the people in this room how challenging and important that really is. We’ve heard a little bit about the great promise of our research and some of the advances that are coming through our research pipeline, new treatments, new guidance for clinicians and caregivers. I want everyone to know that we want to work with you. By working together, I’m confident that we will tailor these new advances to meet the individual needs of the patients and populations that we serve.
Tabak: Nora, what would you like to add?
Volkow: This afternoon, I met with two parents who told me the story of how they lost their daughter to an overdose. They showed me pictures of this fantastic girl, along with her drawings. Whenever we think about overdose deaths in America, the sheer number—75,000—can make us indifferent. But when you can focus on one person and feel the love surrounding that life, you remember the value of this work.
Like in COVID, substance use disorders are a painful problem that we’re all experiencing in some way. They may have upset our lives. But they may have brought us together and, in many instances, brought out the best that humans can do. The best, to me, is caring for one another and taking the responsibility of helping those that are most vulnerable. I believe that science has a purpose. And here we have a purpose: to use science to bring solutions that can prevent and treat those suffering from substance use disorders.
Tabak: Thanks to both of you for this enlightening conversation.
