Recommendations for Addressing In-Hospital Substance Use From a National Delphi Consensus Process

JAMA Network Open

This survey study utilized a 3-round Delphi consensus process to identify best practices for addressing in-hospital substance use. A panel of 38 addiction experts developed 84 consensus-based and patient-centered recommendations which can inform local responses, including policies, to address in-hospital substance use.

Injectable-Only Overlapping Buprenorphine Starting Protocol in a Low-Threshold Setting

JAMA Network Open

Injectable-only buprenorphine protocols are an exciting new strategy for buprenorphine initiation, particularly in the fentanyl era. This is a cohort study of 95 patients with moderate to severe opioid use disorder who received care in a low-threshold setting in Seattle. 79% of patients included in the study were experiencing homelessness or living in permanent supportive housing. Patients selected a long-acting injectable (LAI) buprenorphine initiation protocol which included three escalating doses of LAI buprenorphine over three days, with no sublingual buprenorphine and without cessation of fentanyl/opioid use. 75% of the patients completed the protocol, and 64% received a second monthly dose of LAI buprenorphine.

Association between housing status and mental health and substance use severity among individuals with opioid use disorder and co-occurring depression and/or PTSD

BMC Primary Care

This is a cross-sectional analysis of associations between housing status and mental health and substance use severity among primary care patients with co-occurring disorders. The study is a sub-analysis using data from the Collaboration Leading to Addiction Treatment and Recovery from other Stresses randomized controlled trial, which tested the Collaborative Care Model for primary care patients with OUD and co-occurring depression and/or PTSD. Of 797 patients in the study, 13% were currently unhoused, 24% were unstably housed, and 63% were stably housed. Those who were unhoused were on average younger and had not used prescribed MOUD in the past 30 days. The analysis found that being unhoused or unstably housed was significantly associated with higher PTSD symptom severity, depression symptom severity, opioid use severity, and opioid overdose risk behaviors compared to those who were stably housed.

Oral methadone versus sublingual buprenorphine for the treatment of acute opioid withdrawal: A triple-blind, double-dummy, randomized control trial

Drug and Alcohol Dependence Researchers compared oral methadone to sublingual buprenorphine for the management of acute opioid withdrawal. Patients at an inpatient drug treatment center in India were randomly assigned to receive either methadone or buprenorphine titrated over days 1-3 to control opioid withdrawal symptoms. Over days 4-10 medications were tapered and stopped by day 11. Completion of treatment was similar in both groups (83% methadone, 82% buprenorphine). Both subjective (SOWS) and objective (COWS) withdrawal symptoms decreased during the treatment, however the buprenorphine group had significantly greater withdrawal symptoms than the methadone group (p=0.009) at the end of treatment (day 10). Opioid craving also decreased in both groups with no significant difference between groups. Authors conclude that methadone is a safe and effective alternative to buprenorphine for management of opioid withdrawal.

Implementation Gaps in US Syringe Service Programs, 2022

JAMA This study performed a cross-sectional analysis of the Syringe Services Programs in the US (SSPUS) dataset to determine implementation gaps. 613 syringe service programs (SSPs) included in the dataset were geocoded to county boundaries, which were then analyzed for urbanicity and SSP need (based on HCV mortality, HIV incidence, and drug overdose mortality). The study found that most high need counties did not have an SSP: 81.2% of high HCV need counties, 69.5% of high HIV need counties, and 75.7% of high overdose need counties did not have an SSP. SSPs were more commonly located in urban counties than suburban or rural counties. The study is limited in that not all SSPs are represented within the SSPUS database; however it highlights important implementation gaps.

Co-involvement of stimulants with opioids in North America: A 'silent epidemic’

Plos Mental Health

The opioid epidemic unfolded in three distinct waves, with the latest being deaths attributed to illegally manufactured synthetic opioids. Using U.S. and Canadian data, this study reviews evidence for a 'silent epidemic' alongside the opioid epidemic that is characterized by the co-ingestion of stimulants including methamphetamine and cocaine leading to an increasing number of deaths. Trends for stimulant and opioid use were analyzed using Joinpoint regression and public interest in the substances was assessed via Google Trends. While stimulant use and its role in deaths are rising, public interest in stimulants has declined since its peak in 2004-05. Co-use leads to more deaths than either drug alone. Urgent strategies are needed to reduce harm and raise awareness among health professionals, policymakers, and the public about the dangers of stimulant-opioid co-use.

Did alcohol facilitate the evolution of complex societies?

Humanities and Social Sciences Communications

This study tested the “drunk” hypothesis, which claims that alcohol promoted social bonding and cooperation, aiding the rise of complex societies. Using data from 186 non-industrial societies, they found a modest positive link between indigenous alcoholic beverages and political complexity, even after controlling for ancestry, environment, and agriculture. Results suggest traditional fermented alcohols provided social benefits that helped societal evolution. However, other factors like agriculture and religion were likely more effective drivers.

Disparities in Treatment and Referral After an Opioid Overdose Among Emergency Department Patients

JAMA Network Open

This cohort study of 1,683 patients assessed if there are racial and ethnic disparities in treatment referral rates among patients in the emergency department (ED) with opioid overdose. It found a statistically significant difference in the proportion of Black patients who received an outpatient treatment referral (5.7%) compared with White patients (9.6%). These findings suggest that Black patients presenting to the ED with opioid overdose may be less likely to receive outpatient treatment referrals, underscoring the need for targeted intervention and enhanced referral processes.
