Law enforcement assisted diversion : qualitative evaluation of barriers and facilitators of program implementation

BACKGROUND : Despite widespread interest in adoption, there has been limited systematic examination of Law Enforcement Assisted Diversion (LEAD) implementation, a model for police-led arrest diversion for those with substance use disorders (SUD). In the fall of 2017, the City of New Haven started a LEAD program. During the first 9 months of the pilot, only 2 clients were successfully diverted from arrest. Therefore, we examined the and barriers and facilitators of LEAD implementation. METHODS : We conducted semi-structured interviews and field observations of LEAD police officers and health care providers between August 2018 and June 2019. Interviews and field observations were analyzed using directed content analysis and guided by the Integrated Promoting Action on Research Implementation in Health Services framework. RESULTS : Lead professionals participated in 19 semi-structured interviews and three field observations. Barriers to arrest diversion implementation included procedural complexity of arrest diversion, concerns about reduced penalties for substance use among officers, stigma of SUDs, and a belief in a punitive role for policing. Facilitators included a positive longitudinal relationship with potential clients and an understanding of SUD as a chronic disease. CONCLUSION : We identified several barriers to LEAD implementation. Our results suggest promotion of SUD as a chronic disease, ongoing training of officers, and positive incentives for entering substance use treatment should be utilized to facilitate implementation.SUPPLEMENTARY MATERIAL : Appendix A: Interview guideThe National Institutes of Health (NIH) and the Department of Veterans Affairs.https://www.elsevier.com/locate/jsat2022-05-14hj2022Psycholog

Primary care engagement is associated with increased pharmacotherapy prescribing for alcohol use disorder (AUD)

Abstract Background Primary care provider skills such as screening, longitudinal monitoring, and medication management are generalizable to prescribing alcohol use disorder (AUD) pharmacotherapy. The association between primary care engagement (i.e., longitudinal utilization of primary care services) and prescribing of AUD pharmacotherapy is unknown. Methods We examined a 5-year (2010–2014) retrospective cohort of patients with AUD, 18 years and older, at an urban academic medical center in the Bronx, NY, USA. Our main exposure was level of primary care engagement (no primary care, limited primary care, and engaged with primary care) and our outcome was any AUD pharmacotherapy prescription within 2 years of AUD diagnosis. Using multivariable logistic regression, we examined the association between primary care engagement and pharmacotherapy prescribing, accounting for demographic and clinical factors. Results Of 21,159 adults (28.9% female) with AUD, 2.1% (n = 449) were prescribed pharmacotherapy. After adjusting for confounders, the probability of receiving an AUD pharmacotherapy prescription for patients with no primary care was 1.61% (95% CI 1.39, 1.84). The probability of AUD pharmacotherapy prescribing was 2.56% (95% CI 2.06, 3.06) for patients with limited primary care and 2.89% (95% CI 2.44, 3.34%) for patients engaged with primary care. Conclusions The percentage of AUD patients prescribed AUD pharmacotherapy was low; however, primary care engagement was associated with a higher, but modest, probability of receiving a prescription. Efforts to increase primary care engagement among patients with AUD may translate into increased AUD pharmacotherapy prescribing; however, strategies to increase prescribing across health care settings are needed

The impact of relaxation of methadone take-home protocols on treatment outcomes in the COVID-19 era.

BACKGROUND: Background: In response to the COVID-19 pandemic, the US Substance Abuse and Mental Health Services Administration (SAMHSA) allowed for an increase in methadone take-home doses for the treatment of Opioid Use Disorder (OUD) in March 2020. OBJECTIVE: To evaluate the effects of the SAMSHA exemption on methadone adherence and OUD-related outcomes. METHODS: A convenience sample of 183 clients (58% female) were recruited from a methadone clinic in the fall of 2019 for a cross-sectional survey. Survey data was linked to clinical records, including urine drug testing (UDT) results for methadone and emergency department (ED) visits at the local hospital. Participants were on stable methadone dosing for 9 months prior to and following March 2020. Methadone adherence was assessed by UDTs; OUD-related outcomes were assessed by overdose events and ED visits. Logistic regression was used to assess the association between change in take-home methadone doses and outcomes. RESULTS: Mean take-home doses increased nearly 200% (11.4 doses/30 days pre-COVID-19 vs. 22.3 post-SAMHSA exemption). ED visits dropped from 74 (40.4%) pre-COVID-19 to 56 (30.6%) post-SAMHSA exemption ( = <0.001). No significant changes were observed in either the number of clients experiencing overdose or those who experienced one or more methadone negative UDTs in the post-SAMHSA exemption period. Adjusted models did not show a significant association between changes in take-home doses and associated outcomes. CONCLUSIONS: Despite a near-doubling of take-home methadone doses during the COVID-19 exemption period, the increase in take-home doses was not associated with negative treatment outcomes in methadone-adherent clients

Methadone prescribing by addiction specialists likely to leave communities without available methadone treatment

Methadone treatment for opioid use disorder is not available in most suburban and rural US communities. We examined 2 options to expand methadone availability: (1) addiction specialty physician or (2) all clinician prescribing. Using 2022 Health Resources and Services Administration data, we used mental health professional shortage areas to indicate the potential of addiction specialty physician prescribing and the location of federally qualified health centers (ie, federally certified primary care clinics) to indicate the potential of all clinician prescribing. We examined how many census tracts without an available opioid treatment program (ie, methadone clinic) are (1) located within a mental health professional shortage area and (2) are also without an available federally qualified health center. Methadone was available in 49% of tracts under current regulations, 63% of tracts in the case of specialist physician prescribing, and 86% of tracts in the case of all clinician prescribing. Specialist physician prescribing would expand availability to an additional 12% of urban, 18% of suburban, and 16% of rural tracts, while clinician prescribing would expand to an additional 30% of urban, 53% of suburban, and 58% of rural tracts relative to current availability. Results support enabling broader methadone prescribing privileges to ensure equitable treatment access, particularly for rural communities

Assessment of Community-Level Vulnerability and Access to Medications for Opioid Use Disorder

Importance: Given that COVID-19 and recent natural disasters exacerbated the shortage of medication for opioid use disorder (MOUD) services and were associated with increased opioid overdose mortality, it is important to examine how a community's ability to respond to natural disasters and infectious disease outbreaks is associated with MOUD access.Objective: To examine the association of community vulnerability to disasters and pandemics with geographic access to each of the 3 MOUDs and whether this association differs by urban, suburban, or rural classification.Design, Setting, and Participants: This cross-sectional study of zip code tabulation areas (ZCTAs) in the continental United States excluding Washington, DC, conducted a geospatial analysis of 2020 treatment location data. Exposures: Social vulnerability index (US Centers for Disease Control and Prevention measure of vulnerability to disasters or pandemics).Main Outcomes and Measures: Drive time in minutes from the population-weighted center of the ZCTA to the ZCTA of the nearest treatment location for each treatment type (buprenorphine, methadone, and extended-release naltrexone).Results: Among 32604 ZCTAs within the continental US, 170 within Washington, DC, and 20 without an urban-rural classification were excluded, resulting in a final sample of 32434 ZCTAs. Greater social vulnerability was correlated with longer drive times for methadone (correlation, 0.10; 95% CI, 0.09 to 0.11), but it was not correlated with access to other MOUDs. Among rural ZCTAs, increasing social vulnerability was correlated with shorter drive times to buprenorphine (correlation,-0.10; 95% CI,-0.12 to-0.08) but vulnerability was not correlated with other measures of access. Among suburban ZCTAs, greater vulnerability was correlated with both longer drive times to methadone (correlation, 0.22; 95% CI, 0.20 to 0.24) and extended-release naltrexone (correlation, 0.15; 95% CI, 0.13 to 0.17).Conclusions and Relevance: In this study, communities with greater vulnerability did not have greater geographic access to MOUD, and the mismatch between vulnerability and medication access was greatest in suburban communities. Rural communities had poor geographic access regardless of vulnerability status. Future disaster preparedness planning should match the location of services to communities with greater vulnerability to prevent inequities in overdose deaths.</p

A conceptual model for understanding post-release opioid-related overdose risk

Abstract Post-release opioid-related overdose mortality is the leading cause of death among people released from jails or prisons (PRJP). Informed by the proximate determinants framework, this paper presents the Post-Release Opioid-Related Overdose Risk Model. It explores the underlying, intermediate, proximate and biological determinants which contribute to risk of post-release opioid-related overdose mortality. PRJP share the underlying exposure of incarceration and the increased prevalence of several moderators (chronic pain, HIV infection, trauma, race, and suicidality) of the risk of opioid-related overdose. Intermediate determinants following release from the criminal justice system include disruption of social networks, interruptions in medical care, poverty, and stigma which exacerbate underlying, and highly prevalent, substance use and mental health disorders. Subsequent proximate determinants include interruptions in substance use treatment, including access to medications for opioid use disorder, polypharmacy, polydrug use, insufficient naloxone access, and a return to solitary opioid use. This leads to the final biological determinant of reduced respiratory tolerance and finally opioid-related overdose mortality. Mitigating the risk of opioid-related overdose mortality among PRJP will require improved coordination across criminal justice, health, and community organizations to reduce barriers to social services, ensure access to health insurance, and reduce interruptions in care continuity and reduce stigma. Healthcare services and harm reduction strategies, such as safe injection sites, should be tailored to the needs of PRJP. Expanding access to opioid agonist therapy and naloxone around the post-release period could reduce overdose deaths. Programs are also needed to divert individuals with substance use disorder away from the criminal justice system and into treatment and social services, preventing incarceration exposure

Altered Spatiotemporal Dynamics of the Mitochondrial Membrane Potential in the Hypertrophied Heart

Chronically elevated levels of oxidative stress resulting from increased production and/or impaired scavenging of reactive oxygen species are a hallmark of mitochondrial dysfunction in left ventricular hypertrophy. Recently, oscillations of the mitochondrial membrane potential (ΔΨm) were mechanistically linked to changes in cellular excitability under conditions of acute oxidative stress produced by laser-induced photooxidation of cardiac myocytes in vitro. Here, we investigate the spatiotemporal dynamics of ΔΨm within the intact heart during ischemia-reperfusion injury. We hypothesize that altered metabolic properties in left ventricular hypertrophy modulate ΔΨm spatiotemporal properties and arrhythmia propensity
