Personalized Feedback Intervention for Alcohol and Opioid Use Among Adults With Chronic Pain
Over one-quarter of American adults engage in hazardous drinking (i.e., a pattern of alcohol consumption that increases risk for harmful consequences), which is the third leading cause of preventable death in the U.S. Rates of hazardous drinking are significantly higher among individuals with (vs. without) chronic pain. Moreover, 20% of individuals prescribed opioids endorse concurrent alcohol and opioid use, which may interfere with chronic pain treatment and lead to dangerous/potentially fatal health effects. No interventions to date have targeted either hazardous drinking or concurrent use of alcohol and opioids in the context of chronic pain. The current four-year R01 builds upon our past work by developing a brief, single-session, computer-based, personalized feedback intervention (PFI) designed to enhance knowledge regarding adverse pain-alcohol-opioid interrelations, increase motivation and intention to reduce hazardous drinking, and reduce positive attitudes and intention regarding concurrent use of alcohol and prescription opioid medications. Specifically, we will develop an integrated PFI for hazardous drinkers with chronic pain who are prescribed opioids (PA-PFI). Our approach will follow a staged model consistent with NIH guidelines for developing and standardizing behavioral interventions. Phase IA activities will involve collecting qualitative and quantitative feedback from three iterative focus groups (N = 21) to refine intervention content and evaluate treatment acceptability and feasibility. Phase IB activities will include a proof-of-concept and highly rigorous randomized clinical trial designed to compare PA-PFI to control PFI (C-PFI) among a sample of 174 hazardous drinkers with chronic pain who are currently prescribed opioid medications. This study represents an important and pivotal step in the larger landscape of translating basic research to more efficacious strategies for reducing hazardous drinking among underserved populations with medical comorbidities. This intervention would be highly disseminable and relevant to millions of hazardous drinkers with chronic pain. Given the collective public health impact of chronic pain, hazardous drinking, and concurrent alcohol-prescription opioid use, we believe the current study will yield findings that enhance scientific knowledge, enhance our understanding of mechanisms in reciprocal pain-alcohol-opioid relations, and inform the development of novel treatments for hazardous drinkers with chronic pain that are adaptable and easily implemented across a variety of healthcare settings.

Enhanced Recovery After Major Surgery and Chronic Pain for Total Knee Arthroplasty
The goal of this interventional clinical trial is to assess opioid consumption 24-48 hrs post anesthesia block among patients undergoing total knee arthroplasty. The main question it aims to answer is: 1\. Is there a difference in opioid consumption 24-48 hours post block administration among patients that receive an adductor canal catheter (ACC) versus adductor canal block (ACB)? Participants will be: * Randomized to receive an adductor canal catheter (ACC) or a sham adductor canal catheter. * Asked to use the Diagnotes application to communicate with the pain doctor while the catheter is in place. * Follow up for up to 6 months post-operation. Researchers will compare the interventional group (ACC) to the control group (sham ACC + ACB) to see if there is difference in opioid consumption and chronic pain at 6 months post-operation.

Opioid Analgesic Reduction Study
The goal is to provide health care professionals, including dentists, with the best possible evidence for clinical decision making when deciding upon analgesics for acute post-surgical pain management, a double-blind, stratified randomized clinical trial will be conducted to test the hypothesis that a combination of over-the-counter non-opioid containing analgesics is at least as, if not more, effective (non-inferior) than the most commonly prescribed opioid analgesic. The impacted 3rd molar extraction model will be used due to the predictable severity of the post-operative pain and generalizability of results. This double-blind, prospective, stratified, randomized pragmatic clinical trial will use the impacted 3rd molar extraction pain model.

Effects of Erector Spinae Plane Block and Paravertebral Block on Early Postoperative Pulmonary Function Test Parameters
The pain experienced by participants after minimally invasive chest surgery (VATS) can make it difficult for them to take deep breaths, which can lead to problems with lung function. This can cause serious problems such as lung collapse, low oxygen levels, and infections, making recovery longer and more difficult. Managing pain well after surgery is important to prevent these problems and speed up recovery. In this study, we aimed to compare two pain relief methods, Erector Spinae Plane Block (ESP) and Paravertebral Block (PVB), in participants who underwent VATS. We will look at which method causes the smallest change in lung function before and after surgery.

Paracervical Injection and Opioid Use After Vaginal Hysterectomy for Prolapse
The goal of the study to see if giving a numbing medicine around the cervix (called a paracervical block) during vaginal hysterectomy with prolapse repair helps people feel less pain and need fewer strong pain medicines afterward. The main question it aims to answer is: • Does receiving a paracervical block at the time of vaginal hysterectomy with prolapse repair reduce postoperative opioid use? Researchers will compare opioid use in participants who receive the an injected numbing medicine (bupivacaine with lidocaine) to those that receive a saltwater liquid placebo. Participants will: * Receive either an injection of the numbing medicine (bupivacaine with lidocaine) or saltwater liquid placebo after they are asleep but before any other parts of the surgery are done * Record and report pain medications used for 7 days after surgery * Report pain scores before discharge from the post anesthesia recovery area on day of surgery as well as 1 and 7 days after surgery * Complete a surgical recovery questionnaire during 6 week postoperative visit * Complete a one page multiple-choice test on pelvic organ prolapse

Opioid Misuse in Patients With Cancer
The success of opioid treatment in terminally ill cancer patients set the stage for extending the same treatment principles to the treatment of all chronic pain conditions including chronic non-cancer pain and chronic pain in cancer, where survival and long-standing chronic disease trajectories are getting more prevalent due to increasing survival rates. In this context, opioid misuse as such has been highly neglected - especially in palliative care, but also in cancer pain management in general. Previous studies have explored the literature on opioid misuse among adult cancer patients, noting that the available evidence is still in its early stages. Limited prospective studies with a wide range of definitions and methodologies for assessing misuse exist. Therefore, it seems highly relevant and justified to study the prevalence of opioid misuse risk in patients with cancer. The hypothesis of this study is that opioid misuse is not uncommon in Danish patients in treatment with opioids for cancer-related pain. Thus, the prevalence of opioid misuse risk among patients with cancer in Danish palliative care units will be investigate.

Improving Communication About Pain and Opioids
The overall goal of this protocol is to pilot test a clinician training intervention that uses standardized patients (trained actors playing patient roles) as instructors who impart communication skills to primary care clinicians. This project will conduct a pilot clinical trial of the intervention developed by the primary investigator in order to evaluate intervention feasibility and generate data to plan a subsequent fully-powered, multisite trial. Primary care clinicians will be randomized to receive either the intervention or control; 48 patients (2 per clinician) will then be recorded during clinic visits with study clinicians and will provide data on post-visit perceptions and health outcomes. Study hypotheses are that visits with clinicians who receive the intervention (versus control) will be associated with more frequent use of targeted communication skills, lower probability of high-risk opioid prescribing, higher patient-reported agreement with treatment plan, and lower pain interference 2 months later.

Auriculo-Nerve Stimulation on Post-Operative Opioid Requirement
The NSS-2 BRIDGE® device (NSS stands for Neuro-Stimulation System) is a disposable device that stimulates the branches of cranial nerves and of the superficial cervical plexus innervating the ear. Because the stimulation of the nerves of the ear by the NSS-2 BRIDGE® device (NBD®) has been shown to modulate pain pathways in rodents, decrease abdominal pain in adolescents with inflammatory bile syndrome and due to the results of our preliminary pilot study, the investigators hypothesized that this technique may also be effective in reducing the requirement for postoperative opioids and provide a non-pharmacological alternative to perioperative opioid use. To establish the role that the stimulation of the nerves of the ear may have in reducing postoperative opioid requirement, the investigators are proposing to conduct a randomized, placebo controlled study in patients undergoing open abdominal or pelvic surgery requiring at least 5 days of hospitalization. Subjects who have signed an informed consent will be randomized in 2 groups (active NBD® group or inactive NBD® group). Furthermore, since preoperative and postoperative mood disorders have been shown to increase postoperative pain levels and opioid requirement by up to 50%, the investigators further hypothesize that the stimulation of the ear nerves by the NSS-2 BRIDGE® effects may be in part mediated by a reduction of the level of anxiety, depression and catastrophizing as assessed using validated questionnaires.
