A mixed methods study on poisoning and injury-related emergency department visits associated with opioids in Canada, 2011 to 2022: from the Canadian hospitals injury reporting and prevention program

BackgroundThe opioid crisis is a serious public health issue in Canada. There have been many surveillance programs and research studies on opioid-related emergency department (ED) visits at a national, provincial, regional or municipal level. However, no published studies have investigated the in-depth contexts surrounding opioid-related ED visits. In addition, few studies have examined injuries other than poisonings in those visits. The objective of this study is to investigate the contextual factors and co-occurrence of poisonings and injuries among the opioid-related ED visits in a Canadian sentinel surveillance system on injuries and poisonings from 2011 to 2022.MethodsThis study used a mixed methods design. The data source was the Canadian Hospitals Injury Reporting and Prevention Program. We first selected all opioid-related ED visits during our study period and then identified the contextual factors through a content analysis of the combination of the narrative description and other variables in the patients’ records. The contextual factors were organized into themes as opioid use context, social resource utilization, bystander involvement, and prior naloxone use. The opioid use context was used as a co-variable to examine the other themes and ED presentations (poisonings and other injuries). Quantitative descriptive approach was used to analyze all the contexts and ED presentations.ResultsThe most common opioid use context was non-prescribed opioid use without intention to cause harm, followed by self-poisoning, children’s exposure, and medication error. Various rare contexts occurred. Paramedics participated in 27.9% of visits. Police and security guards were involved in 5.1% and 2.3% of visits, respectively. Child welfare or social workers were involved in 0.4% of visits. Bystanders initiated 18.9% of the ED visits. Naloxone use before arriving at the ED occurred in 23.4% of the visits with a variety of administrators. The majority of patients presented with poisoning effects, either with poisoning effects only or with other injuries or conditions.ConclusionsOur study has provided an in-depth analysis of contextual factors and co-occurrence of poisonings and injuries among opioid-related ED visits in Canada. This information is important for ED programming and opioid-related poisoning and injury intervention and prevention.

Cross-National Analysis of Opioid Prescribing Patterns: Enhancements and Insights from the OralOpioids R Package in Canada and the United States

Background: The opioid crisis remains a significant public health challenge in North America, highlighted by the substantial need for tools to analyze and understand opioid potency and prescription patterns. Methods: The OralOpioids package automates the retrieval, processing, and analysis of opioid data from Health Canada’s Drug Product Database (DPD) and the U.S. Food and Drug Administration’s (FDA) National Drug Code (NDC) database. It includes functions such as load_Opioid_Table, which integrates country-specific data processing and Morphine Equivalent Dose (MED) calculations, providing a comprehensive dataset for analysis. The package facilitates a comprehensive examination of opioid prescriptions, allowing researchers to identify high-risk opioids and patterns that could inform policy and healthcare practices. Results: The integration of MED calculations with Canadian and U.S. data provides a robust tool for assessing opioid potency and prescribing practices. The OralOpioids R package is an essential tool for public health researchers, enabling a detailed analysis of North American opioid prescriptions. Conclusions: By providing easy access to opioid potency data and supporting cross-national studies, the package plays a critical role in addressing the opioid crisis. It suggests a model for similar tools that could be adapted for global use, enhancing our capacity to manage and mitigate opioid misuse effectively.

Trends in Substance Use Disorder-Related Emergency Department Visits in California: An Analysis of 46 Million Visits From 2006 to 2011.

To better understand the development of the growing opioid crisis in the early 21st century, the authors studied trends in substance use disorder among 46,132,211 emergency department (ED) visit discharges in California between 2006 and 2011. Utilizing the California State Emergency Department Database, the authors identified substance use based on International Classification of Diseases, Ninth Revision codes. Tabular and multivariable analysis methods were applied. ED visits were considered clustered at the level of patient. The authors observed a notable increase in substance use prevalence from 7.32 ± 6.07 to 12.21 ± 9.35 per 1000 ED visits. Nonopioid substance use was more prevalent among individuals aged ≤ 50 years old. Opioid use disorder (OUD) was associated with a higher mortality rate in the ED. In 2011, OUD was significantly higher among American Indians visiting the ED. A multivariable analysis revealed that OUD was an independent predictor for increased ED visits after controlling for demographic factors. Despite an overall decrease in mortality rate, opioid-related ED visits showed a higher mortality rate, underscoring the grave consequences of OUD. Nonopioid substance use was prevalent among younger age groups, suggesting a need for age-specific interventions. A major finding was the elevated OUD among American Indians, indicating persistent health disparities impacting this demographic. OUD was an independent risk factor for excess ED visits, which could strain health care systems. The authors suggest strategies like nonopioid pain management, community-level programs, and bridging ED with outpatient treatment facilities to mitigate the opioid crisis and ED overutilization. These findings advocate for tailored public health strategies, addressing the underlying disparities to combat the opioid epidemic effectively.

The Use of Natural Language Processing Methods in Reddit to Investigate Opioid Use: Scoping Review.

The growing availability of big data spontaneously generated by social media platforms allows us to leverage natural language processing (NLP) methods as valuable tools to understand the opioid crisis. We aimed to understand how NLP has been applied to Reddit (Reddit Inc) data to study opioid use. We systematically searched for peer-reviewed studies and conference abstracts in PubMed, Scopus, PsycINFO, ACL Anthology, IEEE Xplore, and Association for Computing Machinery data repositories up to July 19, 2022. Inclusion criteria were studies investigating opioid use, using NLP techniques to analyze the textual corpora, and using Reddit as the social media data source. We were specifically interested in mapping studies' overarching goals and findings, methodologies and software used, and main limitations. In total, 30 studies were included, which were classified into 4 nonmutually exclusive overarching goal categories: methodological (n=6, 20% studies), infodemiology (n=22, 73% studies), infoveillance (n=7, 23% studies), and pharmacovigilance (n=3, 10% studies). NLP methods were used to identify content relevant to opioid use among vast quantities of textual data, to establish potential relationships between opioid use patterns or profiles and contextual factors or comorbidities, and to anticipate individuals' transitions between different opioid-related subreddits, likely revealing progression through opioid use stages. Most studies used an embedding technique (12/30, 40%), prediction or classification approach (12/30, 40%), topic modeling (9/30, 30%), and sentiment analysis (6/30, 20%). The most frequently used programming languages were Python (20/30, 67%) and R (2/30, 7%). Among the studies that reported limitations (20/30, 67%), the most cited was the uncertainty regarding whether redditors participating in these forums were representative of people who use opioids (8/20, 40%). The papers were very recent (28/30, 93%), from 2019 to 2022, with authors from a range of disciplines. This scoping review identified a wide variety of NLP techniques and applications used to support surveillance and social media interventions addressing the opioid crisis. Despite the clear potential of these methods to enable the identification of opioid-relevant content in Reddit and its analysis, there are limits to the degree of interpretive meaning that they can provide. Moreover, we identified the need for standardized ethical guidelines to govern the use of Reddit data to safeguard the anonymity and privacy of people using these forums.

Effect of chronic delivery of the NOP/MOR partial agonist AT-201 and NOP antagonist J-113397 on heroin relapse in a rat model of opioid maintenance.

The opioid crisis persists despite availability of effective opioid agonist maintenance treatments (methadone and buprenorphine). Thus, there is a need to advance novel medications for the treatment of opioid use and relapse. We recently modeled maintenance treatment in rats and found that chronic delivery of buprenorphine and the mu opioid receptor (MOR) partial agonist TRV130 decreases relapse to oxycodone seeking and taking. In contrast, chronic delivery of the buprenorphine analog BU08028 had mixed effects on different heroin relapse-related measures. Here, we tested the effect of the mixed nociceptin (NOP) receptor/MOR partial agonist AT-201 and the NOP receptor antagonist J-113397 on different heroin relapse-related measures. We trained male and female rats to self-administer heroin (6-h/d, 14-d) in context A and then implanted osmotic minipumps containing AT-201 (0, 3.8, or 12mg/kg/d) or J-113397 (0, 12.6, or 40mg/kg/d). Next, we tested the effect of chronic delivery of the compounds on (1) incubation of heroin seeking in a non-drug context B, (2) extinction responding reinforced by heroin-associated discrete cues in context B, (3) context A-induced reinstatement of heroin seeking, and (4) reacquisition of heroin self-administration in context A. In females, AT-201 modestly increased reacquisition of heroin self-administration and J-113397 modestly decreased incubation of heroin seeking. The compounds had no effect on the other relapse-related measures in females, and no effect on any of the measures in males. The NOP/MOR partial agonist AT-201 and the NOP antagonist J-113397 did not mimic buprenorphine's inhibitory effects on relapse in a rat model of opioid maintenance treatment.

Integrating Nursing Practice and Policy in Opioid Overdose Prevention: Analysis of the Opioid-Overdose Reduction Continuum of Care Approach Practice Guide.

To present a comprehensive analysis of the Opioid-Overdose Reduction Continuum of Care Approach (ORCCA) Practice Guide 2023, evaluating its alignment with Russell and Fawcett's conceptual model of nursing and health policy and highlighting the implications for nursing practice and policy. This paper employs a policy analysis framework to evaluate the ORCCA Practice Guide, using Russell and Fawcett's conceptual model as a lens to assess the policy's structure and implementation. The analysis is framed by Russell and Fawcett's conceptual model, focusing on the dimensions of efficacy, effectiveness, equity and justice. This framework assesses how well the ORCCA's strategies align with these dimensions in the context of nursing and health policy. Key findings indicate that the ORCCA's strategies are integral to nursing practice, particularly in frontline interventions such as education, naloxone distribution and Medication for Opioid Use Disorder (MOUD) delivery. The integration of these strategies demonstrates a significant impact on the opioid crisis, enhancing the roles nurses play in opioid overdose prevention. The ORCCA Practice Guide represents a multifaceted approach to addressing the opioid crisis, with strong alignment to the conceptual model used for analysis. It underscores the essential role of nurses in implementing and refining opioid overdose reduction strategies. The study highlights the critical need for nursing involvement in policy formation and practice implementation, suggesting that nurses are key to advancing comprehensive opioid overdose prevention measures. This study addresses the problem of opioid overdoses and the need for effective interventions. The main findings show the importance of nurse-driven strategies in opioid crisis management. The research impacts public health policy and practice, particularly influencing how nursing approaches are integrated into overall health strategies for overdose prevention. No patients, caregivers, or members of the public were involved in conducting this analysis.

Exploring Disparities in Opioid Utilization: An Analysis Comparing Red River Métis to All Other Manitobans

Objective and ApproachTo address the opioid crisis within the Red River Métis (RRM) Community, understanding opioid use is crucial to empower regional health authorities to adapt health programs, services, and policies to meet their unique needs effectively. The investigation utilized focus groups with a Community-Based Participatory Research and Collective Consensual Data Analytics Procedure (CBPR/CCDAP) approach. Additionally, a population-based retrospective cross-sectional study for fiscal years 2006/07–2018/19 was conducted using administrative data from a population research data repository. Rates of prescription opioid dispensing (RPOD) and mean morphine equivalents (MEQ) were compared between RRM and all other Manitobans (AOM) aged 10 years or older. ResultsThe rate of prescription opioid dispensing and MEQ/person were found to be consistently higher among RRM compared to AOM in each study year (p < 0.001). While the RPOD declined among AOM over the study period, it did not change among RRM. Key findings revealed RRM were concerned about how opioids impacted their communities, and felt the need for increased addiction treatment resources, including Red River Métis culture-specific programs. ConclusionThe evidence demonstrates higher RPOD and MEQ among RRM compared to AOM, suggesting elevated risk of opioid-related harms. Focus group feedback reinforces the need for tailored interventions. ImplicationsFuture policies and programs targeting the opioid crisis should prioritize the unique needs of populations like the RRM, requiring tailored, culturally appropriate interventions for effective crisis management.

The Opioid Crisis, Impact on Children, and Mitigation Strategies

The opioid epidemic continues to make a significant impact on public health across multiple domains. While patients with opioid use disorders (OUD) remain in the face of this epidemic, the effect of the opioid epidemic, including on children and families, remains unheard. The impact of the opioid crisis is felt the most by individuals who do not use opioids themselves, with children being the most vulnerable victims of the opioid epidemic, an aspect of this epidemic that receives far less attention. The socio-ecological model approach is used to increase awareness of the lived experiences of children growing up in households with OUD and to promote the incorporation of treatment considerations based on available research. A literature review was conducted using computer-based searches using PubMed, PsycINFO, Medline, and Google Scholar databases. This entailed searching according to the following keywords (or stems when possible): opioids, opioid overdose, parental opioid use, child maltreatment, resilience, and adverse childhood experiences. Keywords were combined by using the Boolean operators "AND" and "OR.". Additionally, the ancestry approach, where potential studies were identified from the reference sections of existing reviews on the association between opioids and children, was used. Given that prenatal opioid use is extensively studied, and our focus was on lived experiences, studies focused solely on the effects of prenatal opioid use were excluded. Selected studies were varied in scope and methodologies. We reviewed the bibliographies of identified studies for additional studies and used both forward and backward searching. The economic cost of OUD and fatal opioid overdose is staggering and estimated to be about $1.02 trillion. Exposure to parental opioid use in childhood can have a significant impact on children's current and future lives. Conversely, for parents with OUD, children often provide a strong motivation for treatment. Children of adults with OUD are at higher risk of early exposure and initiation of opioid misuse. Opioid exposure in childhood, in turn, is associated with adult opioid misuse and OUD. Screening at healthcare visits is advocated to detect and mitigate the impact of OUD on children. The odds of using school-based mental health services are greater in boys compared to girls. Emerging evidence suggests that boys manifest less resiliency in the face of parental opioid exposure. This indicates a more nuanced understanding of the developmental outcomes of parental opioid exposure.

A Geospatial Study of Opioid Overdose Risk in Diverse Regions

Over the past two decades fatalities from opioid overdoses (OD) in the United States have increased at an alarming rate, and there exist regional disparities in the number of opioid fatalities within the US. A comprehensive understanding of the underlying factors contributing to this geographic variation remains elusive however. In this study, we consider the Social Vulnerability Index (SVI) census variables and their influence on opioid overdose within diverse geographic regions, each exhibiting different socio-economic factors. To investigate these disparate outcomes, we use Social Vulnerability Index data from the year 2018 alongside mortality data obtained from the CDC WONDER database. The factors that contribute to opioid OD fatalities can vary from one region to another due to differences in socio-economic characteristics. To investigate these regional differences, we have chosen a set of variables for each region which are relevant to understanding the opioid OD fatalities in three different geographical regions: the Washington D.C metropolitan area, Wyoming, Tennessee. The impact of each factor on the epidemic's propagation varies between these regions however. To identify patterns in socioeconomic factors driving the opioid crisis, we applied methods from topological data analysis to identify potential correlations between social vulnerability factors and the distribution of drug overdose fatalities. In conclusion, our work highlights the importance of the socio-economic factors in understanding the dynamics of the opioid epidemic.

Designing a Data Dashboard for Health Departments and Overdose Fatality Review Teams

IntroductionOverdose Fatality Review (OFR) teams within health departments rely on data from multiple isolated sources to study the opioid crisis. Recently, we linked electronic health record data with state agency data to form a regional Substance Misuse Data Commons (SMDC) using privacy-preserving record linkage. Our goal in this study was to use human factors design principles to design a data dashboard for OFR teams using the linked datasets that will overcome current barriers within OFR workflows. MethodsWe utilized NASA task load surveys, semi-structured interviews, and design sessions with end users to identify data needs for an optimal dashboard design. We assessed current workloads, data collection processes, and desired future state. We subsequently performed iterative design sessions for the generation and evaluation of low-fidelity prototypes. To overcome issues with privacy and security, we used synthetic data in a cloud-based platform to represent the SMDC for simulation. ResultsEleven OFR organizers participated. Pre-dashboard surveys on existing workflow showed high mental workload associated with data aggregation and case review, identifying a need for more accessible, comprehensive data. In our low-fidelity dashboard demo with synthetic data, iterative design adjustments were made in data visualization, storyline organizations, and theme-based data aggregation across pre-hospital and hospital data. ConclusionsWe refined the data dashboard prototype into a high-fidelity version, set for further usability and human factors evaluation. We addressed privacy and security concerns through synthetic data use while the real-world data is maintained in a HIPAA-secure Azure cloud environment with access for approved users.

Lessons Learned From Developing Dashboards to Support Decision-Making for Community Opioid Response by Community Stakeholders: Mixed Methods and Multisite Study.

Data dashboards are published tools that present visualizations; they are increasingly used to display data about behavioral health, social determinants of health, and chronic and infectious disease risks to inform or support public health endeavors. Dashboards can be an evidence-based approach used by communities to influence decision-making in health care for specific populations. Despite widespread use, evidence on how to best design and use dashboards in the public health realm is limited. There is also a notable dearth of studies that examine and document the complexity and heterogeneity of dashboards in community settings. Community stakeholders engaged in the community response to the opioid overdose crisis could benefit from the use of data dashboards for decision-making. As part of the Communities That HEAL (CTH) intervention, community data dashboards were created for stakeholders to support decision-making. We assessed stakeholders' perceptions of the usability and use of the CTH dashboards for decision-making. We conducted a mixed methods assessment between June and July 2021 on the use of CTH dashboards. We administered the System Usability Scale (SUS) and conducted semistructured group interviews with users in 33 communities across 4 states of the United States. The SUS comprises 10 five-point Likert-scale questions measuring usability, each scored from 0 to 4. The interview guides were informed by the technology adoption model (TAM) and focused on perceived usefulness, perceived ease of use, intention to use, and contextual factors. Overall, 62 users of the CTH dashboards completed the SUS and interviews. SUS scores (grand mean 73, SD 4.6) indicated that CTH dashboards were within the acceptable range for usability. From the qualitative interview data, we inductively created subthemes within the 4 dimensions of the TAM to contextualize stakeholders' perceptions of the dashboard's usefulness and ease of use, their intention to use, and contextual factors. These data also highlighted gaps in knowledge, design, and use, which could help focus efforts to improve the use and comprehension of dashboards by stakeholders. We present a set of prioritized gaps identified by our national group and list a set of lessons learned for improved data dashboard design and use for community stakeholders. Findings from our novel application of both the SUS and TAM provide insights and highlight important gaps and lessons learned to inform the design of data dashboards for use by decision-making community stakeholders.

Intrathecal administration of MCRT produced potent antinociception in chronic inflammatory pain models via μ-δ heterodimer with limited side effects

An important goal in the opioid field is to discover effective analgesic drugs with minimal side effects. MCRT demonstrated potent antinociceptive effects with limited side effects, making it a promising candidate. However, its pharmacological properties and how it minimizes side effects remain unknown. Various mouse pain and opioid side effect models were used to evaluate the antinociceptive properties and safety at the spinal level. The targets of MCRT were identified through cAMP measurement, isolated tissue assays, and pharmacological experiments. Immunofluorescence was employed to visualize protein expression. MCRT displayed distinct antinociceptive effects between acute and chronic inflammatory pain models due to its multifunctional properties at the μ opioid receptor (MOR), µ-δ heterodimer (MDOR), and neuropeptide FF receptor 2 (NPFFR2). Activation of NPFFR2 reduced MOR-mediated antinociception, leading to bell-shaped response curves in acute pain models. However, activation of MDOR produced more effective antinociception in chronic inflammatory pain models. MCRT showed limited tolerance and opioid-induced hyperalgesia in both acute and chronic pain models and did not develop cross-tolerance to morphine. Additionally, MCRT did not exhibit addictive properties, gastrointestinal inhibition, and effects on motor coordination. Mechanistically, peripheral chronic inflammation or repeated administration of morphine and MCRT induced an increase in MDOR in the spinal cord. Chronic administration of MCRT had no apparent effect on microglial activation in the spinal cord. These findings suggest that MCRT is a versatile compound that provides potent antinociception with minimal opioid-related side effects. MDOR could be a promising target for managing chronic inflammatory pain and addressing the opioid crisis.

Racial Differences in Medications for Opioid Use Disorder Initiation in a Carceral Setting.

The opioid overdose crisis significantly affects marginalized communities, with people of color experiencing higher rates of overdose and barriers to treatment. The syndemic of opioid use disorder and mass incarceration exacerbates racial health disparities. Some carceral facilities offer medication for addiction treatment, though no significant research explores differences in type of treatment uptake by race in these settings. This study focuses on the racial differences in medications for opioid use disorder (MOUD) preferences among incarcerated individuals. A retrospective cohort study was conducted at the Rhode Island Department of Corrections (RIDOC), examining MOUD-type preferences (buprenorphine or methadone) among incarcerated individuals. The study utilized RIDOC electronic medical records from January 1, 2017 to December 31, 2022, involving 3533 unique incarceration events. Participants were categorized by race (White vs non-White) and MOUD status (new initiation vs community continuation), with logistic regression models. The study found no direct racial disparity in preferences for MOUD type. However, an interaction between race and MOUD initiation status significantly influenced MOUD-type preference. Among those initiating MOUD during incarceration, non-White individuals were more likely to choose buprenorphine compared to their White counterparts. This research provides new insights into the intersection of race, incarceration, and MOUD preferences. While direct racial disparities in MOUD type were not observed, the analysis uncovered a notable interaction effect: race influences the relationship between MOUD initiation status and the selected MOUD treatment during incarceration. Specifically, data demonstrate that the likelihood of choosing buprenorphine varies significantly based on both racial background and whether the treatment was initiated during incarceration or in the community. Further research is needed in different geographic settings to understand the broader implications to help guide equitable healthcare delivery in jails and prisons.

The devastating dance between opioid and housing crises: Evidence from OxyContin reformulation

Housing instability and drug misuse are two of the United States' most pressing challenges, each bearing profound health and societal consequences. A crucial yet largely underexplored question is the extent to which the opioid crisis has intensified housing instability. Our study ventures into this relatively uncharted nexus, investigating how the OxyContin reformulation, a pivotal moment in the U.S. opioid epidemic, impacted eviction rates. Employing a dose-response Difference-in-Differences model and analyzing eviction data from 2004 to 2016, we demonstrate that the OxyContin reformulation precipitated a significant increase in evictions, especially in areas with weak eviction protections or limited access to psychiatric treatment resources. Channel analyses reveal increased marijuana initiation and heightened mental and physical health issues following the reformulation. Moreover, the OxyContin reformulation leads to greater reliance on the Supplemental Nutrition Assistance Program, signaling an escalated financial strain on governmental resources. Finally, we find evidence of increased marital disruption post-reformulation. Our findings underscore the urgent need for collaborative efforts between public health and housing authorities to address both the opioid and housing crises.

Community-Based Medications First for Opioid Use Disorder - Care Utilization and Mortality Outcomes.

A large treatment gap exists for people who could benefit from medications for opioid use disorder (MOUD). People OUD accessing services in harm reduction and community-based organizations often have difficulty engaging in MOUD at opioid treatment programs and traditional health care settings. We conducted a study to test the impacts of a community-based medications first model of care in six Washington (WA) State communities that provided drop-in MOUD access. Participants included people newly prescribed MOUD. Settings included harm reduction and homeless services programs. A prospective cohort analysis tested the impacts of the intervention on MOUD and care utilization. Intervention impacts on mortality were tested via a synthetic comparison group analysis matching on demographics, MOUD history, and geography using WA State agency administrative data. 825 people were enrolled in the study of whom 813 were matched to state records for care utilization and outcomes. Cohort analyses indicated significant increases for days' supply of buprenorphine, months with any MOUD, and months with any buprenorphine for people previously on buprenorphine (all results p<0.05). Months with an emergency department overdose did not change. Months with an inpatient hospital stay increased (p<0.05). The annual death rate in the first year for the intervention group was 0.45% (3 out of 664) versus 2.2% (222 out of 9893) in the comparison group in the 12 months; a relative risk of 0.323 (95% CI 0.11-0.94). Findings indicated a significant increase in MOUD for the intervention group and a lower mortality rate relative to the comparison group. The COVID-19 epidemic and rapid increase in non-pharmaceutical-fentanyl may have lessened the intervention impact as measured in the cohort analysis. Study findings support expanding access to a third model of low barrier MOUD care alongside opioid treatment programs and traditional health care settings.

Rethinking leadership approaches for community-wide opioid crisis intervention: harnessing positive inquiry to unearth front-line insight

State Mandates On Naloxone Coprescribing Associated With Short-Term Increase In Naloxone Codispensing.

In the midst of the opioid crisis in the US, efforts to mitigate overdose risks have become paramount, leading some states to introduce mandates for coprescribing the life-saving overdose reversal drug naloxone. These mandates were designed to specifically address people receiving opioid analgesics who had an elevated risk for overdose. This included people receiving high opioid dosages, those concurrently using benzodiazepines, or those with a history of substance use disorder or overdose. Using a nationally representative, multipayer cohort of patients receiving prescription opioids, we investigated how naloxone codispensing rates changed at the state level from 2016 to 2021 among patients with an elevated risk for overdose. Then we used controlled interrupted time series analyses to assess mandates' longitudinal impact on naloxone codispensing in ten states that implemented mandates. We observed an immediate and significant increase in the naloxone codispensing rates in eight states after the implementation of mandates. Nevertheless, in five of these states, the codispensing rates exhibited a subsequent downward trend after the initial increase. State mandates show potential for improving naloxone codispensing; however, mandates alone might not be adequate for sustained change. Further research is needed to identify strategies complementing and enhancing the impact of mandates in combating the overdose crisis.

Social complexity of a fentanyl vaccine to prevent opioid overdose conference proceedings: Radcliffe Institute for Advanced Study conference proceedings

Despite significant public health attention and investment, hundreds of thousands of individuals have suffered fatal opioid overdose since the onset of the opioid crisis. Risk of opioid overdose has been exacerbated by the influx of fentanyl, a powerful synthetic opioid, into the drug supply. The National Institutes of Health Helping End Addiction Long-term (HEAL) Initiative is supporting the development of vaccines targeting fentanyl to protect against overdose. If successful, a vaccine would induce anti-fentanyl antibodies to sequester fentanyl (but not other opioids) in the blood, preventing fentanyl from crossing into the brain and reaching the central nervous system where it can cause overdose. Introduction of an overdose preventing strategy that relies on a vaccine to confer passive protection may be impactful. However, vaccines are poorly understood by the public and politicized. Moreover, the overdose ecosystem is complex and extends across numerous social, economic, medical, and cultural systems. As such, optimal use of a vaccine strategy to address overdose may benefit from multidisciplinary consideration of the social, ethical, and systemic factors that influence substance use and overdose that may also impact the acceptability of a fentanyl vaccine and related implementation strategies.In March 2022, Dr. Elissa Weitzman convened a two-day conference at the Harvard Radcliffe Institute for Advanced Study on the Social Complexity of a Fentanyl Vaccine to Prevent Opioid Overdose. In all, 19 professionals from diverse disciplines (medicine, psychology, history, ethics, immunology, vaccinology, communications, policy) attended the conference and led discussions that centered on population health and epidemiology, history of medicine and frameworks for understanding substance use, ethics, decision-making and attitudes, and operational issues to the question of a novel immunotherapy targeting fentanyl overdose. Participants also debated the risks and benefits of vaccine administration in response to fictional clinical case vignettes. A summary of the conference presentations and discussions follows.
