Understanding the Costs of Using Implementation Facilitation to Implement Emergency Department-Initiated Buprenorphine

Buprenorphine, when prescribed in the emergency department (ED), increases the chances for treatment engagement and retention among patients with opioid use disorder (OUD). The patient uptake and clinical administration of ED-initiated buprenorphine for OUD, however, has been slow despite evidence of its effectiveness. Implementation facilitation (IF), a strategy that leverages external facilitators and a local […]

Health and Economic Outcomes of Addressing Encampments of Individuals Using Opioids

Lead author Hana Zwick, a research data analyst at the Syndemics Lab, and colleagues published a new simulation modeling study in JAMA Network Open to understand the public health and economic outcomes of strategies that arrest, disperse, or house people who live in encampments and experience high-risk opioid use compared to the encampment status quo.

A Cost-Effectiveness of Implementation Facilitation to Promote Emergency Department–Initiated Buprenorphine for Opioid Use Disorder

In the last eight years, emergency departments (EDs) have seen an influx of visits related to opioid use disorder (OUD). For the same reason, researchers have been citing EDs to be a critical setting and reachable moment for initiating OUD medications, the gold standard of care. Buprenorphine is advantageous as a low-barrier OUD treatment compared […]

Improving Care for Opioid Use Disorder in the Criminal-Legal System

Substance use disorders (SUD), and especially opioid use disorder (OUD), are prevalent within the criminal-legal system.  Recently, there has been increased alignment of OUD care across the criminal-legal system with the patient-centered American Society of Addiction Medicine guidelines. Whether by choice or through legislation, carceral facilities are increasingly offering FDA-approved medications for OUD (MOUD), which […]

Budget Impact Tool for the Incorporation of Medications for Opioid Use Disorder into Jail/Prison Facilities

Despite evidence that medications for opioid use disorder (MOUD), namely methadone, buprenorphine, and naltrexone, provided at the point of incarceration improve the well-being of the individual and the public, financial and administrative limitations in jail/prison healthcare often serve as barriers to this recommended first-line treatment for OUD. In fact, evidence indicates that more than 80% […]

Addressing Statistical Issues Encountered in Conducting Prospective Economic Evaluations Alongside Clinical Trials

Conducting an economic evaluation alongside a randomized clinical trial provides valuable information for clinicians, insurers, and policy stakeholders. Integrating an economic evaluation within a trial provides researchers the opportunity to collect patient-level data at multiple time points on both cost and effectiveness outcomes, and to measure the comparative impact of treatments on these outcomes while […]

Weighing the Costs and Benefits of Initiating Extended-release Injectable Naltrexone Compared to Buprenorphine-naloxone

Naltrexone and buprenorphine are two effective medications for opioid use disorder (OUD). Naltrexone, which is typically given as a monthly extended-release injection (XR-NTX), and daily oral buprenorphine, which is typically combined with naloxone (BUP-NX), are prescribed in outpatient or office-based medical settings. XR-NTX patients, however, need to complete detoxification before starting treatment. Results from a […]

Characterizing Initiation, Use, and Discontinuation of Extended-Release Buprenorphine in a Nationally Representative United States Commercially Insured Cohort

Medications for opioid use disorder (MOUD) are evidence-based treatments that help people reduce or stop using opioids. However, high discontinuation rates of MOUD pose a barrier to reducing opioid-related overdoses. Extended-release buprenorphine (XR-BUP) is a relatively new MOUD, approved in late 2017, that has the potential to increase retention because of its monthly dosing schedule. Currently, there is […]
