Tools to implement measurement-based care (MBC) in the treatment of opioid use disorder (OUD): toward a consensus.

Background: The prevalence and associated overdose death rates from opioid use disorder (OUD) have dramatically increased in the last decade. Despite more available treatments than 20 years ago, treatment access and high discontinuation rates are challenges, as are personalized medication dosing and making timely treatment changes when treatments fail. In other fields such as depression, brief measures to address these tasks combined with an action plan-so-called measurement-based care (MBC)-have been associated with better outcomes.

Addiction Medicine Treatment Utilization by Race/Ethnicity Among Adolescents With Substance Use Problems Before Versus During the COVID-19 Pandemic.

Purpose: To examine changes in addiction medicine treatment utilization during the COVID-19 pandemic among adolescents (aged 13-17 years) and differences by race/ethnicity.

Methods: We compared treatment initiation (overall and telehealth), engagement, and 12-week retention between insured adolescents with substance use problems during pre-COVID-19 (March to December 2019, n = 1,770) and COVID-19 (March to December 2020, n = 1,177) using electronic health record data from Kaiser Permanente Northern California.

A patient activation intervention in primary care for patients with chronic pain on long term opioid therapy: results from a randomized control trial.

Background: Given significant risks associated with long-term prescription opioid use, there is a need for non-pharmacological interventions for treating chronic pain. Activating patients to manage chronic pain has the potential to improve health outcomes. The ACTIVATE study was designed to evaluate the effectiveness of a 4-session patient activation intervention in primary care for patients on long-term opioid therapy.

Association of initial opioid prescription duration and an opioid refill by pain diagnosis: Evidence from outpatient settings in ten US health systems.

Objective: The Centers for Disease Control and Prevention's 2022 Clinical Practice Guideline for Prescribing Opioids for Pain cautioned that inflexible opioid prescription duration limits may harm patients. Information about the relationship between initial opioid prescription duration and a subsequent refill could inform prescribing policies and practices to optimize patient outcomes. We assessed the association between initial opioid duration and an opioid refill prescription.

Prescription Opioid Dose Reductions and Potential Adverse Events: a Multi-site Observational Cohort Study in Diverse US Health Systems.

Background: In response to the opioid crisis in the United States, population-level prescribing of opioids has been decreasing; there are concerns, however, that dose reductions are related to potential adverse events.

Objective: Examine associations between opioid dose reductions and risk of 1-month potential adverse events (emergency department (ED) visits, opioid overdose, benzodiazepine prescription fill, all-cause mortality).

Design: This observational cohort study used electronic health record and claims data from eight United States health systems in a prescription opioid registry (Clinical Trials Network-0084).

Nurse Care Management for Opioid Use Disorder Treatment: The PROUD Cluster Randomized Clinical Trial.

Importance: Few primary care (PC) practices treat patients with medications for opioid use disorder (OUD) despite availability of effective treatments.

Objective: To assess whether implementation of the Massachusetts model of nurse care management for OUD in PC increases OUD treatment with buprenorphine or extended-release injectable naltrexone and secondarily decreases acute care utilization.

Design, Setting, And Participants: The Primary Care Opioid Use Disorders Treatment (PROUD) trial was a mixed-methods, implementation-effectiveness cluster randomized clinical trial conducted in 6 diverse health systems across 5 US states (New York, Florida, Michigan, Texas, and Washington).

Telemedicine-delivered treatment for substance use disorder: A scoping review.

Introduction: The COVID pandemic prompted a significant increase in the utilization of telemedicine (TM) for substance use disorder (SUD) treatment. As we transition towards a "new normal" policy, it is crucial to comprehensively understand the evidence of TM in SUD treatment. This scoping review aims to summarize existing evidence regarding TM's acceptability, quality, effectiveness, access/utilization, and cost in the context of SUD treatment in order to identify knowledge gaps and inform policy decisions regarding TM for SUDs.
