Rural Expanded Access to OUD Care & Linkage Using Toxicologists for Telehealth Initiated Treatment

The overarching goal of this project is to increase the availability of OUD treatment in rural counties in the state of Georgia by using Emergency Department (ED)-based telehealth strategies to initiate MOUD and connect patients to treatment. The investigators will implement a novel collaboration between rural EDs, medical toxicologists at the Georgia Poison Center (GPC), peer recovery coaches (PRCs) and RCOs throughout Georgia to bridge the gap between OUD treatment need in rural EDs and specialty physician availability at the GPC. Research activities will be conducted during two broad phases, at three rural EDs in Georgia: planning and implementation. During the planning phase, aggregate data will be obtained to determine each ED's existing practices treating patients with OUD and opioid withdrawal. During the implementation phase, the researchers will prospectively study a poison center OUD consultation and PRC intervention as it is rolled out at each site, collecting participant-level data. Sites will be rolled into the implementation phase in a stepped-wedge fashion, so there will be times when some sites are in the planning phase while others are in the implementation phase.

Evaluation of Neuroinflammation FNOS PET/CT in HIV (+) and (-) Subjects With OUD and Healthy Controls

The purpose of this research is to measure the extent of inflammation in the brain between different groups of participants using a radioactive tracer called \[18F\]NOS. A radioactive tracer is a type of imaging drug that is labeled with a radioactive tag and injected into the body. This study will see how the tracer is taken up in the brain using an imaging scan called Positron Emission Tomography / Computed Tomography (PET/CT). Participants will undergo approximately 60 minutes of dynamic scanning of the brain starting at approximately the time of injection of \[18F\]NOS. Participants are required to have a brain MRI performed within 1 year prior to study enrollment, or if the subject has not had a brain MRI that is deemed acceptable for use for this study they will be asked to undergo a research brain MRI after they have consented for this study.

Nonopioid Pain Control Regimen After Open Reduction and Internal Fixation of Traumatic Fractures

An open reduction and internal fixation is a painful procedure requiring intensive postoperative pain management. Traditionally, opioid analgesia has been the gold standard for postoperative pain control. However, given the harmful side effect profile and opioid epidemic in the United States, it is advantageous to use alternate forms of analgesia. Multimodal pain control captures the effectiveness of different analgesic modalities and maximizes analgesia while minimizing side effects. The theory behind their use is that agents with different mechanisms of action work synergistically in preventing acute pain. Objective: To measure postoperative pain control in patients in two treatment arms of ORIF of the clavicle: a treatment group given a nonopioid pain control regimen, and a standard of care control group given standard opioid pain control regimen. Study Design: A randomized single blinded standard of care controlled clinical trial comparing pain management interventions. All adult patients scheduled for an ORIF following a traumatic fracture by fellowship trained Trauma surgeons will be eligible for inclusion. Patients will be excluded if their medical history presents known allergies or intolerance to Motrin, Lyrica, Tylenol, Zanaflex, substantial alcohol or drug abuse, and pregnancy, history of narcotics within 6 months of surgery, renal impairment, peptic ulcer disease, GI bleeding. On the day of surgery, patients will be randomized to receive a nonopioid pain control regimen or an opioid regimen using a computer-generated sequence. If pain is uncontrolled, patients will also be sent home with a prescription with 10 pills of 5 mg of Oxycodone for breakthrough pain. The amount of oxycodone taken will be recorded. Patients can call the resident on call, available 24-hours per day, if additional pain control is needed. Treatment: All patients will undergo previously scheduled ORIF of the clavicle in standard fashion and be randomized to the non-narcotic pain regimen vs the narcotic pain regimen.

Facilitating Opioid Care Connections

In response to the opioid crisis in New York State (NYS), where the propose project will take place, the Unified Court System (UCS) developed a new treatment court model - the opioid court model (OCM) - designed around 10 practice guidelines to address the flaws of existing drug courts and reduce overdose (OD), opioid use disorder (OUD), and recidivism via rapid screening and linkage to medication for opioid use disorder (MOUD). In 2018, NYS began to expand the OCM across NYS. Yet, given the innovation of the OCM, the exact barriers to implementation in disparate counties with a range of resources - and the strategies to overcome them - are largely unknown. The research team proposes to integrate evidence-based implementation strategies to refine and evaluate the Opioid Court Model Rigorous Implementation Science for Effectiveness (OCM RISE) intervention, an implementation intervention that will allow the OCM, as framed by the 10 practice guidelines, to be scaled up across NYS.

Dexmedetomidine and Ketamine in VATS Surgery

Postoperative pain after VATS surgery is significant and associated with moderate to high post operative morphine requirements, which can cause opioid related side effects and delay postoperative recovery. To reduce this requirement, multimodal analgesia with non opioid medication such as dexmedetomidine and ketamine can be used. These drugs have demonstrated significant opioid-sparing properties after various types of surgeries. However, very little is known about their ability to do so in VATS surgery. Also, their relative opioid-sparing properties have not been compared, and it is not known whether their combined use can lead to an additional opioid-sparing effect. The primary goal of this study will be to determine the impact of a combined intra operative infusion of ketamine and dexmedetomidine on postoperative morphine requirements in patients undergoing elective VATS, compared to both these drugs infused separately. The hypothesis is that this combined infusion will lead to a 30% further reduction in morphine requirements, 24h after surgery, compared to both these drugs infused separately.

Postsurgical Pain and Opioid Use in Older Adults: Effects of Mild Cognitive Impairment

Mild cognitive impairment (MCI) affects a substantial proportion of older adults undergoing major surgery and may alter pain processing, pain experience, and opioid use after surgery. This prospective observational cohort study will compare older adults with MCI and cognitively intact older adults undergoing major orthopedic and complex spine procedures. Participants will undergo preoperative assessment of cognitive function, quantitative sensory testing, heart rate variability, clinical pain, and biomarkers associated with Alzheimer's disease risk. Postoperative pain trajectories, opioid use, pain responsiveness, and cognitive outcomes will be evaluated for six months following surgery. The study aims to determine whether MCI is associated with differences in postoperative pain and opioid use outcomes and whether APOE4 status and plasma amyloid beta 42/40 ratio contribute to observed differences.

Quadro-Iliac Plane Block for Postoperative Analgesia in Laparoscopic Inguinal Hernia Repair

The goal of this randomized controlled trial is to learn whether an ultrasound-guided quadro-iliac plane block (QIPB) reduces opioid use and pain after laparoscopic inguinal hernia repair in adults aged 18-65 years. The main question it aims to answer is: does QIPB reduce total tramadol consumption during the first 24 postoperative hours? Researchers will compare patients who receive QIPB under general anesthesia with patients who receive no block. All participants will receive the same general anesthesia, multimodal analgesia and intravenous tramadol patient-controlled analgesia (PCA). Pain scores, PCA use, quality of recovery (QoR-15), nausea and vomiting, and time to discharge will be recorded during the first 24 hours.

Mindfulness in Fracture Recovery and Reduction of Opioid Reliance: Evaluating the Feasibility of Implementing a Brief, Mindfulness-based Intervention to Manage Pain and Anxiety Before and After Fracture Surgery

Breaking a bone is not only physically painful but also emotionally overwhelming. Patients often experience intense pain, anxiety, and uncertainty as they are rushed to hospital, undergo emergency treatment, and prepare for surgery. After surgery, many continue to struggle with pain and rely on opioid medications, which carry serious risks including addiction. In the context of our current opioid epidemic, it's critical that alternative treatment strategies are urgently evaluated. Mindfulness is a practice that helps people focus on the present and has been shown to reduce stress and pain in other settings. In this trial, patients with broken arms or legs who need surgery at Hamilton General Hospital will be randomly assigned to one of two groups who will listen to a two-part, audio recording before and after surgery. Those in the interventional group will engage in a 7-minute audio-guided mindfulness exercise before surgery to help reduce anxiety, and another 7-minute audio-guided mindfulness exercise after surgery to help manage pain. Those in the control group will listen to a 7-minute educational audio recording before surgery and again after surgery. The main goal is to see if this approach is practical-can enough patients be recruited, and will they complete the audio recordings? The study will also look at early signs of whether the intervention helps reduce pain, anxiety, and opioid use six weeks after surgery. If feasible, a larger study can be conducted to determine if these exercises can help patients manage pain and reduce their need for opioids after surgery. If successful, this simple, low-cost approach could be widely used in hospitals to support recovery and reduce reliance on pain medications.

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

Encouraging Abstinence Behavior in a Drug Epidemic: Optimizing Dynamic Incentives

Combatting the rise of the opioid epidemic is a central challenge of U.S. health care policy. A promising approach for improving welfare and decreasing medical costs of people with substance abuse disorders is offering incentive payments for healthy behaviors. This approach, broadly known as "contingency management" in the medical literature, has repeatedly shown to be effective in treating substance abuse. However, the use of incentives by treatment facilities remains extremely low. Furthermore, it is not well understood how to design optimal incentives to treat opioid abuse. This project will conduct a randomized evaluation of two types of dynamically adjusting incentive schedules for people with opioid use disorders or cocaine use disorders: "escalating" schedules where incentive amounts increase with success to increase incentive power, and "de-escalating" schedules where incentive amounts decrease with success to improve incentive targeting. Both schemes are implemented with a novel "turnkey" mobile application, making them uniquely low-cost, low-hassle, and scalable. Effects will be measured on abstinence outcomes, including longest duration of abstinence and the percentage of negative drug tests. In combination with survey data, variation from the experiment will shed light on the barriers to abstinence more broadly and inform the understanding of optimal incentive design.

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.
