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 […]

New Rules for Methadone Doses at Home Did Not Increase Overdoses

Methadone is known as the gold standard treatment for opioid use disorder, with some experts calling it a “miracle drug” for its effectiveness in blocking the effects of other opioids and preventing withdrawal. Since 1972, its use has been limited to specialized opioid treatment programs, with patients required to travel to a clinic for daily dosing. This […]

Offering Buprenorphine in Homeless Shelters in Massachusetts Projects Life- and Cost-saving Results

Overdose is the leading cause of death among people with opioid use disorder (OUD) who are experiencing homelessness. Innovative care models that meet this population outside of office-based settings can improve access to buprenorphine, a medication for treating OUD, and avert fatal overdoses. In this study, Avik Chatterjee, lead author and addiction specialist at Boston […]

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 […]

Insurance Instability for Patients with Opioid Use Disorder in the Year After Diagnosis

Access to health insurance is crucial to gaining the necessary diagnostic and therapeutic services to achieve and maintain good health. Insurance is especially necessary to access medications for opioid use disorder (MOUD) as the cost of MOUD can be a barrier to staying in treatment. If insurance coverage is disrupted, MOUD treatment may be more […]

Informing Evidence-Based Medicine for Opioid Use Disorder Using Pharmacoeconomic Studies

Since 2021, over 100,000 individuals have died each year from a drug overdose, with approximately 76 percent of those deaths involving opioids.  As the US health care system contends with this growing health crisis, improved access to evidence-based medication treatment for opioid use disorder (OUD) is imperative. Pharmacoeconomics, a branch of health economics used to evaluate comparative clinical, person-centered, and economic outcomes […]
