Introduction: Washington State's Hub and Spoke (HS) approach aims to improve availability of opioid use disorder (OUD) treatment. Washington initially funded six hubs with expertise in medications for opioid use disorder (MOUD) that built care networks with referral and treatment partners (spokes). We assessed outcomes for the initial HS cohort, considering the role of HS and treatment characteristics.

Objective: To examine whether Medicaid managed care plan (MCP) utilization management policies for buprenorphine-naloxone and injectable naltrexone are related to key state Medicaid program policy decisions.

Data Sources And Study Setting: We abstracted data on state Medicaid regulatory and policy information from publicly available sources and publicly available insurance benefit documentation from all 241 Medicaid MCPs operating in 2021.

Study Design: In this cross-sectional study, we used bivariate and multivariate analyses to examine whether Medicaid MCP prior authorization and quantity limits on receipt of buprenorphine and injectable naltrexone were associated with key state Medicaid choices to leverage federal funds to expand coverage and eligibility (Medicaid expansion, 1115 waivers) and to regulate Medicaid MCPs (uniform preferred drug lists, medical loss ratio remittance).

Faced with a growing opioid overdose crisis, emergency departments (EDs) are increasingly hiring peers-people with lived experiences of addiction and recovery-to work with patients in the ED who have opioid use disorders (OUDs) or who have experienced an opioid overdose. Despite a clear need for more support for patients with OUD and rapid expansion in grant funding for peer programs, there are limited data on how these programs affect clinical outcomes and how they are best implemented within the ED. In this narrative review, we synthesize the existing evidence on how to develop and implement peer programs for OUD in the ED setting.

Objective: Extending prior research that has found that people with traumatic brain injury (TBI) experience worse substance use treatment outcomes, we examined whether history of TBI was associated with discontinuation of medication to treat opioid use disorder (MOUD), an indicator of receiving evidence-based treatment.

Setting: We used MarketScan claims data to capture inpatient, outpatient, and retail pharmacy utilization from large employers in all 50 states from 2016 to 2019.

Participants: We identified adults aged 18 to 64 initiating non-methadone MOUD (ie, buprenorphine, injectable naltrexone, and oral naltrexone) in 2016-2019.

Background: In the US, much of the research into new intervention and delivery models for behavioral health care is funded by research institutes and foundations, typically through grants to develop and test the new interventions. The original grant funding is typically time-limited. This implies that eventually communities, clinicians, and others must find resources to replace the grant funding -otherwise the innovation will not be adopted.

Importance: Adverse outcomes associated with opioid use disorder (OUD) are disproportionately high among people with disabilities (PWD) compared with those without disability. A gap remains in understanding the quality of OUD treatment for people with physical, sensory, cognitive, and developmental disabilities, specifically regarding medications for OUD (MOUD), a foundation of treatment.

Objective: To examine the use and quality of OUD treatment in adults with diagnosed disabling conditions, compared with adults without these diagnoses.

Background: Mortality due to opioid use continues to increase; effective strategies to improve access to treatment for opioid use disorder (OUD) are needed. While OUD medications exist, they are used infrequently and often not available in residential addiction treatment settings. CMS provides expanded opportunities for Medicaid reimbursement of treatment in residential facilities and requires states that request Medicaid SUD Waivers to provide a full continuum of care including medication treatment.

Introduction: Opioid overdose deaths are increasing, and improving access to evidence-based treatment is necessary. Emergency department (ED) initiation of treatment for opioid use disorder (OUD) via medications and referral to treatment is one approach that leverages a critical health care entry point for individuals with OUD. Efforts to engage patients in treatment through the ED are growing, but systematic analysis of program features as implemented and challenges across different models remains limited.

Objective: The study sought to investigate whether consistent use of the Veterans Health Administration's My HealtheVet (MHV) online patient portal is associated with improvement in diabetes-related physiological measures among new portal users.

Materials And Methods: We conducted a retrospective cohort study of new portal users with type 2 diabetes that registered for MHV between 2012 and 2016. We used random-effect linear regression models to examine associations between months of portal use in a year (consistency) and annual means of the physiological measures (hemoglobin A1c [HbA1c], low-density lipoproteins [LDLs], and blood pressure [BP]) in the first 3 years of portal use.

Summary: As states plan to implement system-wide change of any kind, it is important to understand program directors' perspectives on challenges they face. This is especially true with quality improvement reforms. Much research has focused on quality improvement in medicine, but there is a gap in our knowledge about programs that treat individuals with drug or alcohol use.

Introduction: Many people drop out of substance use disorder (SUD) treatment within the first few sessions, which suggests the need for innovative strategies to address this. We examined the effectiveness of incentive-based contracting for Maine's publicly funded outpatient (OP) and intensive outpatient (IOP) SUD treatment, to determine its potential for improving treatment engagement and retention.

Methods: Maine's incentive-based contract with federally block grant-funded OP and IOP treatment agencies created a natural experiment, in which we could compare treatment engagement and retention with a group of state-licensed treatment agencies that were not part of the incentive-based contract.

Background: Some US payers are starting to vary payment to providers depending on patient outcomes, but this approach is rarely used in substance use disorder (SUD) treatment.

Purpose: We examine the feasibility of applying a pay-for-outcomes approach to SUD treatment.

Methods: We reviewed several relevant literatures: (1) economic theory papers that describe the conditions under which pay-for-outcomes is feasible in principle; (2) description of the key outcomes expected from SUD treatment, and the measures of these outcomes that are available in administrative data systems; and (3) reports on actual experiences of paying SUD treatment providers based on patient outcomes.

Behavioral health care has been slow to take up robust efforts to improve patient safety. This lag is especially apparent in inpatient psychiatry, where there is risk for physical and psychological harm. Recent investigative journalism has provoked public concern about instances of alleged abuse, negligence, understaffing, sexual assault, inappropriate medication use, patient self-harm, poor sanitation, and inappropriate restraint and seclusion.
