Article Synopsis
  • - The study explores the challenges faced by community-based providers of medications for opioid use disorders (MOUD) when collaborating with recovery courts, which mandate treatment instead of incarceration but rely on outside resources for support.
  • - Providers reported that a lack of knowledge about recovery courts, negative feelings toward the criminal justice system, and staffing shortages hinder effective collaboration, while complex communication requirements and unresponsive courts were common obstacles.
  • - Despite these barriers, direct interactions with recovery court staff and shared goals of helping individuals in recovery were identified as key factors that could enhance collaboration and improve access to care.

Objectives: As carceral settings increasingly offer medications for opioid use disorders (MOUD), community-based providers will need to navigate relationships with correctional agencies to ensure continuity of MOUD upon release. Although collaboration has been identified as critical between agencies, limited research is available that details how providers can work with jails. We describe the perspectives of MOUD providers about their experiences collaborating with jails that had recently begun to offer MOUD.

Article Synopsis
  • In recent rural U.S. studies, individuals who use drugs (PWUD) are increasingly combining opioids with stimulants like methamphetamine and cocaine.
  • Among 2,705 PWUD surveyed, 74% reported using both opioids and stimulants, with 76% having undergone hepatitis C virus (HCV) testing.
  • Those who used opioids alone had lower rates of HCV testing, and those using both opioids and stimulants were less likely to have received anti-HCV medication compared to those using other drugs.

Background: Over the last two decades, houselessness and drug-related epidemics both have expanded from urban to rural regions across the United States (US). However, our understanding of the relationship between rural houselessness, drug use, and drug-related harms has not kept pace. The current study addresses this gap by describing houselessness among a large cohort of people who use drugs (PWUD) from rural communities across 10 states.

Hepatitis C virus (HCV) disproportionately affects people who inject drugs (PWID). Although HCV has become universally curable since the arrival of direct-acting antivirals, barriers exist to facilitating care and cure in this historically hard-to-reach population, including limited testing and healthcare services and healthcare stigma, issues that are compounded in rural areas. Telehealth is effective in increasing access to HCV care and cure, but innovative approaches of testing and care are required to fully address the need among rural PWID, which led to our study examining a mobile telehealth model for treating HCV.

Background: Incarceration provides an opportunity for health interventions, including opioid use disorder (OUD) treatment and prevention of opioid-related overdoses post-release. All FDA-approved forms of medication for OUD (MOUD) treatment were mandated in several Massachusetts jails in 2019, with some jails offering extended-release buprenorphine (XR-Bup). Little is known about patient perspectives on and experiences with XR-Bup in carceral settings.

Background: The United States' (US) opioid overdose epidemic has evolved into a combined stimulant/opioid epidemic, a pattern driven in part by mitigating opioid overdose risk, variable substance availability, and personal preferences. This study aimed to investigate the association between self-reported substance preference (heroin or methamphetamine) and behavioral/health outcomes among individuals who used both heroin and methamphetamine in the rural US.

Methods: The Rural Opioid Initiative is a consortium of 8 research cohorts from 10 states and 65 rural counties that recruited individuals reporting past 30-day injection of any substance or opioid substance use by any route from 1/2018 to 3/2020.

Article Synopsis
  • Most patients engaged in treatment for opioid use disorder (OUD) initially, but retention dropped significantly over time, with only 17.1% remaining in treatment after 24 months.
  • Data showed that patients with opioid-positive tests at the start had a lower chance of achieving continuous abstinence, while those who tested opioid-negative had higher success rates.
  • Early achievement of abstinence was crucial; patients who maintained sobriety for the first 6 months were much more likely to stay in treatment for the following year or two, highlighting the need for interventions aimed at supporting early stability in high-risk individuals.

Background: Opioid-related overdose is the leading cause of death for people recently released from incarceration, however treatment with medications for opioid use disorder (MOUD) during incarceration can reduce the mortality risk. This study seeks to qualitatively analyze perceptions of post-release overdose risk from the perspectives of people who received MOUD while incarcerated in one of eight Massachusetts jails during 2021-2022 using the Risk Environment Framework to guide analyses.

Methods: N = 38 participants with lived experience of MOUD treatment during incarceration who are now living in the community were interviewed on factors that may contribute to or protect against post-release overdose risk.

Introduction: Despite abundant evidence in the surgical and critical care literature demonstrating inferior outcomes in transfused patients, liberal use of blood transfusion, particularly after the initial unit, remains common in vascular surgery. We therefore sought to investigate the incremental risk of each additional unit of blood transfused intraoperatively for patients undergoing elective open repair of abdominal aortic aneurysm (AAA) with regards to postoperative mortality and complications.

Methods: Patients in the Vascular Quality Initiative registry undergoing elective open infrarenal AAA repair from 2003 to 2020 were included.

Background: Hospitalization presents an opportunity to begin people with opioid use disorder (OUD) on medications for opioid use disorder (MOUD) and link them to care after discharge; regrettably, people admitted to the hospital with an underlying OUD typically do not receive MOUD and are not connected with subsequent treatment for their condition. To address this gap, we launched a multi-site randomized controlled trial to test the effectiveness of a hospital-based addiction consultation team (the Substance Use Treatment and Recovery Team (START)) consisting of an addiction medicine specialist and care manager team that provide collaborative care and a specified intervention to people with OUD during the inpatient stay. Successful implementation of new practices can be impacted by organizational context, though no previous studies have examined context prior to implementation of addiction consultation services (ACS).
