Usual Care Intervention Research Evaluating the Impact of a Personalized Pharmaceutical Plan on the Duration of Opioid Treatment in Non-cancerous Pain

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.

Leveraging Social Networks to Increase COVID-19 Testing Uptake

This two-year project will adapt and conduct a trial examining the ability of two recruitment strategies, chain-referral and credible messenger, to reach those who use opioids and other substances in order to increase their uptake of onsite point of care COVID-19 testing that will be delivered in two community based organizations (CBOs): Alliance for Positive Change and Argus Health Inc. In Phase 1, Adapt two implementation strategies to support COVID-19 testing uptake and sustainability, adapting elements of existing efficacious social network-based interventions via a CBPR approach. In Phase 2, we will examine and compare the efficacy of two sets of implementation strategies on (i) reach, (ii) testing uptake, (iii) service delivery (i.e. quarantine, medical care, contact tracing) and (iv) sustainability for individuals who use opioids and other drugs. In Phase 3, Elucidate and compare the system/organizational-, staff-, and individual-level factors that influence implementation (i.e. fidelity, acceptability, feasibility, sustainability) of the strategies to develop a plan for dissemination and scale-up in other CBOs who serve opioid and other substance using individuals in NYC.

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.

Understanding the Acute Pain Phenotype in Patients Undergoing Surgery

The goal of this observational study is to learn about how regional anesthesia (numbing medication) affects pain in patients with different psychosocial phenotypes such as different levels of concern about pain, sleep issues, and anxiety, who are having surgery. The main questions are: 1. Do psychosocial factors such as concerns about pain, sleep, anxiety affect the effectiveness of regional anesthesia? 2. Do psychosocial factors and regional anesthesia affect the amount of opioids used after surgery? 3. Do psychosocial factors and regional anesthesia affect development of chronic postsurgical pain?

Treating Polysubstance Use Using a Novel Digital Technology

The goal of this clinical trial is to determine the effects of an app to reduce opioid and cocaine use when layered atop methadone treatment as usual among people using both opioids and cocaine. The main questions it aims to answer are: * Do people who use the app remain in methadone treatment longer than people who receive only treatment as usual? * Do people who use the app report using opioids and/or cocaine less often, and do they report better improvements in their quality of life, than people who receive only treatment as usual? * Does using the app more lead to better methadone treatment outcomes among people using the app? Participants in this study will be randomly assigned to receive either the app or methadone treatment as usual. Participants randomly assigned to the treatment as usual group will receive access to methadone services as normally provided, including scheduled access to medications, information about the consequences of opioid and other drug use, and any onsite services (including group based interventions and/or 12-step programs). Those randomized into the app-using group will receive all the same services as the treatment as usual group, but will also be given a phone with the app already installed, or will have the app installed on their existing phone if they already have one. At random times throughout the week, the app will ask participants to submit drug tests for opioids and cocaine, which participants will be able to do remotely without having to physically "go to" a testing site. For each test that demonstrates the participant hasn't used opioids or cocaine, the participant will be rewarded with money directly into a debit card. Participants will also be able to earn rewards for picking up treatment-related medications, attending onsite appointments, and other treatment-related activities.

A Pain and Coordination Plan for Reduced Opioid Use After Accidental Injuries

This clinical trial aims to lower the number of people who use opioids and improve the quality of health in patients who have experienced accidental injury by implementing a Pain and Coordination Plan (PAC-plan). The PAC-plan will be given upon discharge from the hospital. The main questions this study aims to answer are: * Can the PAC-plan reduce opioid use in patients after accidental injuries? * Can the PAC-plan increase quality of life in patients after accidental injuries? * Is implementation of the PAC-plan after accidental injuries cost-effective? Participants will be randomly assigned to the PAC-plan or usual care. The PAC-plan includes: * an opioid management plan upon discharge from the hospital * an appointment with his/her general practitioner within 2-4 weeks after discharge * the general practitioner will be given the opportunity for increased collaboration with the hospital specialists Participants in both groups will be asked to answer questionnaires about their health at discharge, and at 6 and 52 weeks after discharge from the hospital. In addition, the researchers will use data from the Norwegian Prescription Database to measure use of opioids and other relevant drugs, the Norwegian Patient Registry (NPR) and the Norwegian Registry for Primary Health Care (KPR) for the use of health care services and Statistics Norway for data on sick leave and other social security benefits.

Overdose Recovery and Care Access (ORCA) Qualitative Stakeholder Interviews and County-level Data

The study is a quasi-experimental investigation of a sub-acute stabilization center (SASC) for people who have had or are at risk for having an opioid overdose and have an encounter with Seattle Fire Department emergency medical services (EMS) in Seattle, WA. Those transported to the SASC are the intervention participants and two comparison groups will be utilized: eligible Seattle EMS patients who opt not to go to the SASC and King County residents, outside of Seattle, who meet the same eligibility criteria. A comparative interrupted time series analysis is planned to study the main effectiveness outcomes. Seattle Fire EMS will assess, refer, and arrange transport for participants to the SASC. The SASC will offer an array of services including post-overdose monitoring, utilization of buprenorphine and methadone for the treatment opioid use disorder and opioid withdrawal, linkage to ongoing care for OUD, and provision of harm reduction services and supplies. The length of stay in the SASC will be limited to less than 24 hours. A continuous process improvement (CPI) approach will monitor and refine the intervention. Characterization of the interventions will be based upon analysis of service utilization patterns over time along with interviews and surveys with stakeholders.

Reducing Opioid Use for Chronic Pain Patients Following Surgery

Patients with chronic pain are often prescribed long-term opioid therapy, despite the serious risks and growing concerns related to opioid use. The Toronto General Hospital has created the world's first multidisciplinary perioperative Transitional Pain Service Program (TPSP) aimed at reducing the incidence and severity of chronic post-surgical pain. The TPSP incorporates a variety of mechanisms and interventions to help patients manage pain and to wean off opioids. The approach consists of: pain education, Acceptance and Commitment Therapy (ACT), and an e-mobile self- management tool to help patients manage chronic pain more effectively. With the TPSP team, the investigators hope to continually assist patients to achieve a balance between the benefits and potential harms of opioid use to promote long-term health and well-being.

Post-Op Pain Control for Prophylactic Intramedullary Nailing.

Nationally, the opioid crisis has become a major epidemic with increasing mortality rates each year. Orthopedic surgeons routinely prescribe narcotics instead of NSAIDs for post-op pain control because of risk of delayed healing and nonunion due to NSAID use. Orthopedic oncology, however, has a unique subset of patients that undergo prophylactic placement of intramedullary femoral nails. Because no fracture is present, these patients do not rely on inflammatory healing factors, allowing for post-op NSAID use. This study sets out to determine the effect of post-op toradol use in addition to opioids compared to solely opioids in patients undergoing prophylactic nailing of the femur.
