The opioid crisis is a growing problem around the world, with prescription opioids being a major contributor to this crisis. They can be prescribed in different chronic and acute settings, such as surgery. This is therefore an event which may mark a first exposure to opioids in many opioid-naive patients and be associated with subsequent long-term use. This long-term persistent opioid consumption (POC) after surgery may be due, among other things, to chronic postsurgical pain (CPSP). Many risk factors have been identified in the development of chronic pain. Some are related to the surgery while others are related to patient characteristics. Of these, preoperative opioid use, pre-existing pain, and psychological history are major factors that increase the risk of POC or CPSP. The population having undergone major abdominal surgery remains poorly represented in studies of postoperative POC. It can be reasonable to think that these patients may have a similar high risk of CPSP and POC as other surgical patients. The potential harmful effects of POC and CPSP may limit the recovery of these patients and impair their quality of life (QoL). The risk factors for CPSP are important to consider when considering POC. While psychological factors related to pain have been shown to be associated with postoperative pain and analgesic use, the association between unrelieved postoperative pain and POC may have been underestimated. Regional anesthesia is frequently used in major abdominal surgery to reduce the risk of acute and chronic postoperative pain. However, data regarding CPSP specifically after major abdominal surgery are lacking, and the role of neuraxial analgesia on its prevention and on postoperative opioid use is unclear. Since little is known about the prevalence of POC after major abdominal surgery and its determinants, the investigators propose to conduct a major abdominal surgery cohort study by examining POC and CPSP using information reported by patients.
Many treatments with WHO grade III opioids are being introduced in the rheumatology department for non-cancerous pain. The duration of this treatment prescribed at discharge is often uncontrolled and sometimes leads to significant addiction. The team at the local pain center recommends an average duration of 28 days for this type of pain. There is a full-time pharmacy intern in the rheumatology department. The aim of this work is to evaluate the impact of a targeted pharmaceutical interview on the duration of the morphine treatment initiated during hospitalization.
The goal of this randomized controlled trial is to test the effectiveness of "TIARAS," a trauma intervention designed to reduce HIV acquisition risk among women who inject drugs (WWID). To be eligible for this study, participants must have been prescribed pre-exposure prophylaxis (PrEP), a medication taken to prevent HIV for Prevention Point Philadelphia, a large harm reduction agency located in Philadelphia (PA, USA). Enrollment in this study lasts for 12-months so that we can see if TIARAS reduces HIV risk immediately after the intervention ends and whether these effects last over time. During the first 3 months, participants engage in contingency management (CM), an evidenced-based intervention to reduce drug use and HIV risk. We will use CM to encourage engagement in PrEP care as well as stimulant/opioid abstinence. Also during the first 3-months, participants are randomly assigned to complete expressive writing exercises to address a previously undisclosed trauma or neutral writing exercises. Half of the participants will be assigned to the trauma writing group and the other half will be assigned to the neutral writing group. To understand the impact of TIARAS on HIV risk, we will collect and analyze data from surveys, interviews, and biological specimen during the 12-month study period. Our main questions are: - Does participation in TIARAS reduce HIV risk among WWID? - If observed, how long do beneficial effects last? - How and why do WWID experience benefits from TIARAS?
Lobectomy is a major, high-risk surgical procedure that in addition to one-lung ventilation (OLV) exerts a potent surgical stress response. An overwhelming immune cell recruitment may lead to excessive tissue damage, peripheral organ injury and immunoparesis. The effect of anesthesia on the immune system is modest, compared to the effects induced by major surgery. However, to an immunocompromised patient, due to cancer and/or other comorbidities, the immunosuppressive effects of anesthesia may increase the incidence of post-operative infections, morbidity, and mortality. Exogenous opioids have been correlated with immunosuppression, opioid-induced hyperalgesia, and respiratory depression, with deleterious outcomes. An Opioid-Free Anaesthesia-Analgesia (OFA-A) strategy is based on the administration of a variety of anaesthetic/analgesic and other pharmacological agents with different mechanisms of action, including immunomodulating and anti-inflammatory effects. Our basic hypothesis is that the implementation of a perioperative multimodal OFA-A strategy, will lead to an attenuated surgical stress response and attenuated immunosuppression, compared to a conventional Opioid-Based Anaesthesia-Analgesia (OBA-A) strategy. The aforementioned effects, are presumed to be associated with equal or improved analgesia and decreased incidence of postoperative infections compared to a perioperative OBA-A technique.
Many prescription opioids following surgery are left unused and are at risk of being misused or diverted. Encouraging proper disposal is important, yet motivating this behavior remains challenging as patients must understand the risks of opioids, the benefits of disposal, and identify opportunities and places to dispose of them safely. Alternative disposal techniques can improve disposal rates but may be lost or forgotten. Applying behavioral economics techniques may lower the barriers and promote disposal. The objective is to test the effect of a specifically timed, mailed, at-home kit on disposal rates following surgery.
This is a randomized double blinded placebo-controlled study, conducted in Lund, Sweden. Patients will be randomized in two groups, with a ratio of 1:1. The experimental arm will receive intravenous Lidocaine perioperatively, and the Control arm will receive placebo, i.e. normal Saline. Postoperative both arms will get routine pain Control with PCA, Patient Controlled Analgesia with an intravenous Oxycodone-infusion. Outcome-measures will include patients pain intensity scoring, and opioid consumption.
The purpose of this study is to provide medication for opioid use disorder (MOUD) with buprenorphine and naloxone, or bup/nx, pre-exposure prophylaxis (PrEP) for HIV prevention, and/or hepatitis C treatment for persons who inject opioids accessing syringe services programs (SSPs), as part of a comprehensive harm reduction program, and assess the acceptability and feasibility of using telemedicine to implement the program. The initial visit will be conducted in person or remotely via telemedicine given COVID-19 protocols at the SSP site in Greensboro, North Carolina (NC); follow-up visits will be conducted via telemedicine.
This study aims to assess the impact of bilateral deep parasternal intercostal plane block on intraoperative opioid consumption in open heart surgery
This project aims to implement a peer-led intervention to support retention and adherence to medications for opioid use disorder among low-income adults in Detroit, as well as a training manual for peer recovery coaches serving similar populations. The approach will serve as a guide to coaches in providing positive reinforcement and helping those in treatment to schedule and engage in valued activities. Researchers will examine the effectiveness of the intervention, supervision and training models, and share results with policymakers and treatment programs.
