Educational Attainment and US Drug Overdose Deaths

Reward deprivation is associated with elevated alcohol demand in emerging adults

Policies vary substantially in terms of providing sources of psychosocial enrichment. Behavioral economic models of substance use and addiction emphasize that deficits in access to substance-free sources of reward increase substance reinforcing value and risk for addiction. The current study used an alcohol demand curve approach to test the hypothesis that various indices of reward deprivation would be associated with elevated alcohol reinforcing efficacy. We examined associations between alcohol demand indices and several facets of reward deprivation in a sample of young adults (N = 1,331; ages 19-25 years) recruited from the United States and Canada who reported recent binge drinking. Additionally, we created an index of cumulative reward deprivation that integrated the various reward facets and examined its association with alcohol demand intensity and maximum expenditure on alcohol. Our findings indicate that reward deprivation is associated with elevated alcohol demand and provide support for alcohol prevention and intervention approaches that emphasize environmental enrichment.

Barriers and facilitators to implementing CareConnect: A telehealth, low-barrier buprenorphine bridge clinic in Philadelphia

INTRODUCTION

Rates of fatal overdose continue to rise in the United States, and most people with opioid use disorder (OUD) are not engaged in evidence-based treatment with medications. In Philadelphia, a city with one of the highest fatal overdose rates in the country, many residents face significant care access barriers. The COVID-19 pandemic - which destabilized the street drug supply and forced many clinics to limit services - worsened this crisis, but also led to regulatory changes that allowed for buprenorphine induction and maintenance visits via telehealth in the U.S. To increase access to buprenorphine across the Philadelphia area and reach individuals who struggle to access care, Penn Medicine developed the CareConnect Warmline in October 2021. CareConnect is embedded in an existing virtual urgent care practice. Staffed by advanced practice providers and substance use navigators (SUNs), CareConnect provides same-day buprenorphine bridge (i.e., short-term) prescriptions and linkage to longitudinal OUD care.

OBJECTIVE

To examine barriers and facilitators to implementing CareConnect from the perspective of key stakeholders, including CareConnect leadership, clinicians, and staff, and attitudes and beliefs about providing care for patients with OUD via this model.

METHODS

In this qualitative descriptive study, we interviewed 14 participants and used thematic analysis to analyze the data. The sample included CareConnect prescribing clinicians, SUNs, and administrative staff.

RESULTS

Our analysis yielded four themes: 1/ CareConnect is a unique program that fills an important care gap; 2/ Benefits of leveraging existing infrastructure; 3/ Importance of an interdisciplinary team; and 4/ Necessity of relationships with outside stakeholders. Prescribing clinicians and administrative staff - most of whom had little experience with OUD care before CareConnect - stressed how embedding the model within an existing virtual clinic and involving experienced SUNs increased their comfort prescribing buprenorphine. However, all participants highlighted how the program's effectiveness is contingent upon buy-in from outside stakeholders, including pharmacists who fill the prescriptions and longitudinal care providers in the community.

CONCLUSIONS

Innovative delivery models can help expand OUD care access to individuals who are poorly served by traditional treatment infrastructure. Our findings provide valuable insight to improve and sustain CareConnect and can guide the development and implementation of future programs nationally.

Prescription opioid use in Israel - the tide has risen, but it's not a tidal wave

The devastating human and financial costs of the ongoing global opioid crisis underscore the need for comprehensive public health strategies, effective treatment programs, and robust policy interventions to mitigate its impact. Regarding Israel, numerous reports highlight a steady increase since 2000 in prescription opioid use and the shift to more potent opioids particularly fentanyl, particularly among more marginalized population groups. In response to growing concern in the country about the rise in prescription opioid use and the consequential risk of opioid use disorder, the Israeli government, together with the country's health service providers, implemented a series of measures to monitor and regulate opioid prescriptions and balance the need for effective pain management with the prevention of opioid abuse and its associated harms. A national opioid data monitoring system is being established, alongside the provision of addiction training for health professionals, the integration of treatment services for opioid use disorder into the nationalized primary healthcare system, and the expansion of harm reduction strategies to mitigate the health risks associated with opioid use. Additional funding for opioid-related research, and for the broader fields of addictions and mental health, is vital. In conclusion, the sum of the evidence suggests that Israel is not facing an "opioid crisis" Continued commitment, resources, and innovative approaches will be crucial to ensure that the rising tide of opioid use in Israel, particularly during and in the aftermath of the ongoing war, will not become a tidal wave.

Associations Between Opioid and Kratom Use in the USA: Differences by Race/Ethnicity and Sexual Orientation

BACKGROUND

Kratom is federally unregulated and is marketed as an opioid alternative despite limited evidence and known negative effects. Disparities in associations between opioid and kratom use may be partly attributed to race/ethnicity and sexual orientation given differences in marketing, use motives, and prescriber practices.

METHODS

Data: 2021 nationally representative National Survey on Drug Use and Health among individuals aged 18 + . We used weighted logistic regression analyses to assess race/ethnicity and sexual orientation as moderators of associations between past-year opioid (1) use (total sample, n = 44,877) and (2) misuse and use disorder (among those with past-year opioid use, n = 10,398) and the outcome of kratom use (lifetime, past year).

RESULTS

26.76% reported past-year opioid use, and among those, 12.20% and 7.54% reported past-year opioid misuse and use disorder, respectively; 1.72% and 0.67% had lifetime and past-year kratom use, respectively. Opioid use was positively associated with lifetime (aOR = 2.69, 95%CI = 1.98, 3.66) and past-year (aOR = 3.84, 95%CI = 2.50, 5.92) kratom use; associations among non-Hispanic Black and Hispanic (vs. non-Hispanic White) participants were weaker (p < 0.01). Among participants reporting past-year opioid use, misuse and use disorder were positively associated with lifetime (aORmisuse = 2.46, 95%CI = 1.60, 3.78; aORuse disorder = 5.58, 95%CI = 2.82, 11.04) and past-year (aORmisuse = 2.40, 95%CI = 1.26, 4.59; aORuse disorder = 3.08, 95%CI = 1.48, 6.41) kratom use; among bisexual (vs. heterosexual) participants, opioid use disorder was associated with a lower probability of lifetime kratom use (p < 0.01).

DISCUSSION

We observed positive associations between opioid and kratom use, with potential disparities among certain racial/ethnic and sexual orientation groups. Research should examine the mechanisms contributing to these differences to inform prevention and intervention efforts.

Understanding and Addressing Widening Racial Inequalities in Drug Overdose

The fourth wave of the United States overdose crisis-driven by the polysubstance use of fentanyl with stimulants and other synthetic substances-has driven sharply escalating racial/ethnic inequalities in drug overdose death rates. Here the authors present a detailed portrait of the latest overdose trends and synthesize the literature to describe where, how, and why these inequalities are worsening. By 2022 overdose deaths among Native and Black Americans rose to 1.8 and 1.4 times the rate seen among White Americans, respectively. This reflects that Black and Native Americans have been disproportionately affected by fentanyl and the combination of fentanyl and stimulants at the national level and in virtually every state. The highest overdose deaths rates are currently seen among Black Americans 55-64 years of age as well as younger cohorts of Native Americans 25-44 years of age. In 2022-the latest year of data available-deaths among White Americans decreased relative to 2021, whereas rates among all other groups assessed continued to rise. Moving forward, Fundamental Cause Theory shows us a relevant universal truth of implementation science: in socially unequal societies, new technologies typically end up favoring more privileged groups first, thereby widening inequalities unless underlying social inequalities are addressed. Therefore, interventions designed to reduce addiction and overdose death rates that are not explicitly designed to also improve racial/ethnic inequalities will often unintentionally end up worsening them. Well-funded community-based programs, with Black and Native leadership, providing harm reduction resources, naloxone, and medications for opioid use disorder in the context of comprehensive, culturally appropriate healthcare and other services, represent the highest priority interventions to decrease inequalities.
