Data suggest that members of minority groups are more likely to develop chronic pain and to have greater pain burden. We will identify a set of promising intervention targets for reducing or eliminating racial/ethnic pain disparities. We will interview adult survivors of serious physical injury, comprised of roughly equal proportions of African-Americans (AA), Latinos, and non-Latino Whites (NLW), and examine their medical records for information on injury severity and medication use in-hospital. Our aims are to determine whether: 1) AA and Latino physical injury survivors experience more severe pain relative to NLW; 2) AA and Latino injury survivors experience greater pain burden relative to NLW counterparts; 3) differences in pain severity burden are linked to a set of target candidates for interventions; and (4) pain outcomes in at-risk minority groups can be linked to a set of target candidates for group-tailored interventions to reduce pain severity and pain burden.

Previous studies found that African American (AA) and low socioeconomic status (SES) patients are less likely to receive guideline-concordant pain care relative to White and high SES patients. According to research and theory, enhancing clinician perspective-taking is a promising strategy for improving the care of AA and low SES patients. We have developed an innovative methodology that utilizes computer-simulated patients and environments to assess, understand, and remediate pain treatment disparities. Our approach allows for the intervention to be individually tailored to each trainee, thereby enhancing its impact. It also allows for individual trainees to gain exposure to a greater range of racially and socioeconomically diverse patients than can normally be obtained in traditional training settings. We hypothesize that our perspective-taking intervention will increase trainees’ knowledge of their own biases, enhance trainees’ empathy toward patients, and reduce trainees’ anxiety/threat toward patients, and that these changes will reduce pain treatment disparities.

This study addresses the public health problem of chronic pain as one of the most feared symptoms in people with cancer. Insufficient relief from pharmacological treatments and the fear of side effects are important reasons for the growing use of complementary pain management approaches in people with cancer. One such approach is music therapy. Although efficacy of music therapy for pain has been established, there are no mechanistic studies clarifying how it works in clinical populations. The overarching goals of this study are to 1) examine mediators and moderators hypothesized to account for the pain-reducing effects of interactive music therapy (IMT) in people with advanced cancer and chronic pain and 2) validate IMT’s theory of action. The results of this study will provide estimated effects sizes of IMT on the mediators and preliminary effect size estimates for the pain outcomes. This information will be instrumental in the development of a subsequent large-scale efficacy trial.

Wound care procedures (WCPs), such as dressing changes, cause moderate to severe pain in 74% of patients, nearly half of whom experience severe pain. Mainstay recommendations to prevent pain during WCPs have focused on either administration of preventive and procedural analgesia or use of expensive, non-adherent dressings. However, it is unclear which patients to target for analgesia or expensive dressings, leading to their inappropriate over- or underuse. To achieve the aims of the study, a comprehensive set of wound, patient, and biological factors will be measured concurrently with pain during a dressing change among a sample of 450 inpatients with open wounds. A predictive model will be developed and biological mechanisms will be examined using logistic regression. The proposed study has the potential to make significant contributions because clinicians will be able to target those patients requiring preventive pain control, thereby eliminating the spiraling impact of painful procedures on nociceptor sensitization.

Prescriptions for narcotic pain relief after surgery result in unintended prolonged opioid use for hundreds of thousands of Americans. Nonpharmacological pain care is effective and recommended by guidelines for perioperative pain while offering a more favorable risk-benefit ratio. However, nonpharmacological pain care is rarely used as first or second-line therapy after surgery. Patient and clinician decision support interventions are effective in encouraging patient-centered and guideline-concordant care, but these strategies have not been tested pragmatically as a bundle in everyday postoperative pain care. The NOHARM trial will first confirm the feasibility of patient-facing and clinician-facing decision support components of an EHR-embedded evidence-based bundle. The investigators will test the bundle in a stepped-wedge cluster randomized trial. They will test a sustainable system strategy that could change the paradigm of perioperative pain management toward nonpharmacological options in a manner that preserves patient function, honors patient values, and maintains availability of opioids as a last resort.

The chronic low back pain (cLBP) subgroup with comorbid depression or anxiety disorders, known as high negative affect (NA), needs better non-opioid, comprehensive pain treatment options. Data shows that the combination of antidepressants (AD) and fear avoidance physical therapy is more efficacious at improving pain, function, depression, and anxiety in cLBP patients with high NA than each treatment alone or a control condition. Research also finds that an enhanced fear avoidance rehabilitation protocol (EFAR; fear avoidance-based physical therapy, pain education, and motivational messaging) further improves outcomes. To address the unmet needs of cLBP patients with high NA, this study will test in a randomized trial whether the combination of AD and EFAR is more effective than each treatment alone at relieving pain, improving function, combating depression, and preventing opioid misuse. This multimodal combination approach of pharmacotherapy and behavioral therapy is novel to the field and has the potential to shift current treatment paradigms.

For patients with end-stage renal disease treated with long-term hemodialysis (HD), the safety and efficacy of behavioral interventions alone or augmented by safer drugs remain untested. This study will perform a multicenter parallel group randomized controlled trial to test the efficacy of two interventions to reduce opioid use in HD patients. Seven hundred and twenty HD patients with significant and ongoing opioid use will be randomly assigned to (1) telehealth cognitive behavioral therapy (CBT) alone, (2) telehealth CBT augmented by transdermal buprenorphine, and (3) usual care, with follow-up for up to one year. The primary outcome will be prescribed morphine milligram equivalent (MME) over the preceding four weeks. Three patient-reported outcomes (interference by pain, functional status, and quality of life) will comprise the secondary outcomes.

The University of Michigan (UM) will lead a Mechanistic Research Center (MRC) as part of the broader BACPAC initiative that will take patients with chronic low back pain (cLBP) and use a patient-centric, SMART design study to follow these individuals longitudinally as they try several different evidence-based therapies while mechanistic studies are overlaid to draw crucial inferences about what treatments will work in what patient endotypes. Interventional Response Phenotyping describes the need in any precision medicine initiative to phenotype participants based on what therapies they do and do not respond to so that one can later link mechanistically distinct disease endophenotypes with those who preferentially respond to therapies targeting those mechanisms.

The opioid crisis has underscored the urgency of alleviating patients’ chronic low back pain (cLBP) with effective therapies, including evidence-based nonpharmacologic approaches. Mindfulness-based stress reduction (MBSR) is now recommended by the American College of Physicians for initial treatment of cLBP. A pragmatic clinical trial (PCT) will inform health care decision makers about whether this program can be implemented in a real-life clinical setting and measure its impact on outcomes. The OPTIMUM (Optimizing Pain Treatment In Medical settings Using Mindfulness) program will integrate and test an evidence-based mindfulness clinical pain program for patients with cLBP in the primary care provider (PCP) setting. It will be conducted with three health care system sites. Four hundred and fifty persons ? 18 years of age with cLBP will be randomized to OPTIMUM + PCP Usual Care or PCP Usual Care.

The goal of this proposal is to conduct a randomized controlled trial to evaluate the comparative effectiveness of conservative behavioral and nonopioid pharmacological treatments (Phase I) and, among nonresponders, the benefits of nonsurgical procedural interventions (Phase II). Aim 1 will evaluate the effectiveness of individual and combined online cognitive behavioral therapy (painTRAINER) and pharmacologic treatment (duloxetine) in improving pain and function for knee osteoarthritis (KOA) patients compared with standard of care. Aim 2 will determine if genicular nerve radiofrequency ablation or intra-articular injection of hyaluronic acid and steroid is more effective in improving outcomes than local anesthetic nerve block or standard of care and help establish the role of these interventional treatments in the overall management of pain in KOA patients. Aim 3 will test whether clinical and psychosocial phenotypes predict short- and long-term treatment response.

Fibromyalgia (FM) is a chronic pain condition characterized by widespread musculoskeletal pain, tenderness, and stiffness associated with fatigue and sleep disturbance. The investigators have recently completed a trial that demonstrated efficacy of active transcutaneous electrical nerve stimulation (TENS) compared with placebo TENS or no treatment in women with FM. While physical therapists are trained in using TENS, it is underused in clinical practice. This application proposes a pragmatic clinical trial of TENS for patients with FM to determine if the addition of TENS to physical therapy (PT) reduces pain, increases PT adherence, and helps achieve functional goals with less drug use. This study will address the critical need for strategies to implement effective nonpharmacologic treatments for FM. Successful completion of this trial will provide generalizable effectiveness data for referring providers, physical therapists, and insurers and will inform future pragmatic trials of nonpharmacologic treatments conducted in PT practices.

The study team developed an mHealth pain self-management intervention for the perioperative period (SurgeryPal) to target psychosocial risk factors and teach pain self-management skills. The goal of this proposal is to establish the effectiveness of the SurgeryPal psychosocial intervention to improve clinically meaningful outcomes in adolescents undergoing major musculoskeletal surgery, and to identify the optimal timing of intervention delivery. The study team will plan for the efficient implementation of a multisite randomized clinical trial at 25 centers in 500 youth ages 12–18 years undergoing spinal fusion surgery and their parents. Participants will be randomized to receive SurgeryPal or attention control condition during the preoperative and postoperative phases. Self-reported pain severity and interference and secondary outcomes will be assessed at baseline, 3-, and 6-months. If effective, this scalable, low cost intervention will allow broad implementation to prevent chronic postsurgical pain in youth.
