Concerns that an opioid antidote could “make things worse”: Profiles of risk compensation beliefs using the Naloxone-Related Risk Compensation Beliefs (NaRRC-B) scale

Virtual opioid poisoning education and naloxone distribution programs: A scoping review

The global opioid poisoning crisis is a complex issue with far-reaching public health implications. Opioid Poisoning Education and Naloxone Distribution (OPEND) programs aim to reduce stigma and promote harm reduction strategies, enhancing participants' ability to apply life-saving interventions, including naloxone administration and cardiopulmonary resuscitation (CPR) to opioid poisoning. While virtual OPEND programs have shown promise in improving knowledge about opioid poisoning response, their implementation and evaluation have been limited. The COVID-19 pandemic has sparked renewed interest in virtual health services, including OPEND programs. Our study reviews the literature on fully virtual OPEND programs worldwide. We analyzed 7,722 articles, 30 of which met our inclusion criteria. We extracted and synthesized information about the interventions' type, content, duration, the scales used, and key findings. Our search shows a diversity of interventions being implemented, with different study designs, duration, outcomes, scales, and different time points for measurement, all of which hinder a meaningful analysis of interventions' effectiveness. Despite this, virtual OPEND programs appear effective in increasing knowledge, confidence, and preparedness to respond to opioid poisoning while improving stigma regarding people who use opioids. This effect appears to be true in a wide variety of populations but is significantly relevant when focused on laypersons. Despite increasing efforts, access remains an issue, with most interventions addressing White people in urban areas. Our findings offer valuable insights for the design, implementation, and evaluation of future virtual OPEND programs.

Longitudinal Assessment of Emergency Responders' Attitudes Toward People Who Overdose and Naloxone Following an Overdose Education Training

BACKGROUND

In addition to teaching overdose recognition and response, overdose education and naloxone distribution (OEND) trainings for emergency responders aim to improve trainee attitudes toward people who use drugs and toward naloxone. This study examines the training effectiveness long term, as well as the extent to which improvements are dependent on profession type or recent experience administering naloxone.

METHODS

A total of 774 emergency responders, consisting of law enforcement officers (LEOs) (n = 624, 81%) and emergency medical service (EMS) personnel (n = 150, 19%), attended OEND trainings and completed surveys immediately prior to ("pre") and following ("post") the training, as well as 6 months later ("follow-up"). Survey items assessed attitudes toward people who have overdosed, naloxone-related risk compensation (ie, "enabling") beliefs, and whether participants had administered naloxone since attending the training. Multiple regression and estimated marginal means were used to evaluate changes in scores.

RESULTS

Emergency responders showed improved attitudes (pre = 2.60, follow-up = 2.45, P < .001) and risk compensation beliefs (pre = 2.97, follow-up = 2.67, P < .001) 6 months following the training. Follow-up scores differed by profession, with LEOs endorsing worse attitudes (difference = 0.55, P = .013) and more risk compensation beliefs (difference = 0.67, P = .014) than EMS. In addition, having recently administered naloxone predicted more negative attitudes (EMS: difference = 0.55, P = .01; LEO: difference = 0.54, P = .004) and risk compensation beliefs (EMS = 0.73, P = .006; LEO = 0.69, P = .002) at follow-up.

CONCLUSION

Six months after an OEND training, emergency responders' attitudes toward people who overdose, and their risk compensation beliefs remained improved. However, LEOs had more negative follow-up attitudes and beliefs compared to EMS. Emergency responders who had administered naloxone had worse attitudes and beliefs at follow-up than those who had not. Of note, our sample evidenced sizable attrition between pre and follow-up assessments, leaving room for selection bias. Future studies should investigate how to mitigate negative effects of administering naloxone on attitudes toward those who overdose, and belief that naloxone is "enabling."

A systematic review exploring healthcare professionals' perceptions of take-home naloxone dispensing in acute care areas

AIMS

To explore healthcare professionals' perceptions and experiences of take-home naloxone initiatives in acute care settings to gain an understanding of issues facilitating or impeding dispensing.

DESIGN

Systematic literature review.

DATA SOURCES

Cochrane, MEDLINE and CINAHL were searched from 15/03/2021 to 18/03/2021, with a follow-up search performed via PubMed on 22/03/2021. The years 2011 to 2021 were included in the search.

REVIEW METHODS

A systematic literature review focused on qualitative studies and quantitative survey designs. Synthesis without meta-analysis was undertaken using a thematic analysis approach.

RESULTS

Seven articles from the United States of America (5), Australia (1) and Canada (1) with 750 participants were included in the review. Results indicate ongoing stigma towards people who use drugs with preconceived moral concerns regarding take-home naloxone. There was confusion regarding roles and responsibilities in take-home naloxone dispensing and patient education. Similarly, there was a lack of clarity over logistical and financial issues.

CONCLUSION

Take-home naloxone is a vital harm reduction initiative. However, barriers exist that prevent the optimum implementation of these initiatives.

IMPACT

What is already known: Deaths due to opioid overdose are a global health concern, with take-home naloxone emerging as a key harm reduction scheme. Globally, less than 10% of people who use drugs have access to treatment initiatives, including take-home naloxone. An optimum point of distribution of take-home naloxone is post-acute hospital care.

WHAT THIS PAPER ADDS

There is role confusion regarding responsibility for the provision of take-home naloxone and patient education. This is exacerbated by inconsistent provision of training and education for healthcare professionals. Logistical or financial concerns are common and moral issues are prevalent with some healthcare professionals questioning the ethics of providing take-home naloxone. Stigma towards people who use drugs remains evident in some acute care areas which may impact the use of this intervention. Implications for practice/policy: Further primary research should examine what training and education methods are effective in improving the distribution of take-home naloxone in acute care. Education should focus on reduction of stigma towards people who use drugs to improve the distribution of take-home naloxone. Standardized care guidelines may ensure interventions are offered equally and take-home naloxone 'champions' could drive initiatives forward, with support from harm reduction specialists.

REPORTING METHOD

This has adhered to the PRISMA reporting guidelines for systematic reviews.

Effectiveness of take ACTION online naloxone training for law enforcement officers

BACKGROUND

Training law enforcement officers (LEOs) to administer naloxone is a recommended strategy to reduce overdose deaths in the United States. To achieve this, an evidence-based and scalable naloxone training curriculum that is easy to use and readily scalable is needed. Convenient web-based training is a flexible method for delivering educational interventions particularly for LEOs who have irregular or shifting schedules. This study examined the effectiveness of a comprehensive web-based naloxone training that was created in partnership with LEOs on their knowledge, confidence, and attitudes regarding naloxone.

METHODS

From May 2019 to September 2020, five law enforcement departments from Michigan participated in web-based naloxone training. A total of 182 LEOs (77% male) were in the final sample based on matching pre-and post-test surveys. LEOs were assessed on knowledge, confidence, and attitudes towards naloxone. Negative binomial and Poisson regression was conducted to assess associations between knowledge, confidence, and attitudes towards naloxone before and after training.

RESULTS

Significant improvements in overdose knowledge and confidence were revealed across all departments with median (IQR) total composite scores for knowledge increasing from 35 (32, 37) to 40 (39, 42) (p < 0.01) and confidence increasing from 18.5 (15, 20) to 20 (20, 25) (p < 0.01). Median (IQR) attitude scores did not change.

CONCLUSION

Our web-based naloxone training was effective in improving knowledge and confidence for LEOs but did not significantly improve LEOs attitudes towards naloxone across most departments. The web-based format is readily scalable and quickly disseminated and meets the immediate need for LEO overdose training. Additional intervention is needed to address the negative attitudes of LEOs regarding naloxone.

The police paradox: A qualitative study of post-overdose outreach program implementation through public health-public safety partnerships in Massachusetts

BACKGROUND

Post-overdose outreach has emerged in the United States as an increasingly common response to non-fatal overdose. This qualitative study investigates the implementation of such programs through public health-public safety partnerships in Massachusetts.

METHODS

We conducted semi-structured interviews with post-overdose outreach team members, overdose survivors, and family members who received outreach. Interview transcripts were inductively analyzed to identify emergent themes and subsequently organized within the framework of Ecological Systems Theory.

RESULTS

Forty-nine interviews were conducted, including 15 police officers (80% male, 100% non-Hispanic White); 23 public health partners (48% male, 87% non-Hispanic White); 8 overdose survivors who received outreach services and 3 parents of survivors who received services (collectively 27% male, 64% non-Hispanic White). Implementation factors identified across all levels (macrosystem, exosystem, mesosystem, and microsystem) of Ecological Systems Theory included key program facilitators, such as access to police data and funding (macro), interagency collaboration (exo), shared recognition of community needs (exo), supportive relationships among team members (meso), and program champions (micro). Common barriers included inherent contradictions between policing and public health mandates (macro), poor local treatment and service capacity (exo), divergent staff views of program goals (exo), overdose survivors' prior negative experiences with law enforcement (meso), difficulty locating overdose survivors (meso), and police officers' lack of qualifications or training in providing psycho-social services (micro).

CONCLUSIONS

Most post-overdose outreach programs in this study were dependent on funding and data-sharing partnerships, which police agencies largely controlled. Yet, police participation, especially during outreach visits presented numerous challenges for engaging overdose survivors and establishing non-coercive linkages with evidence-based services, which may undermine the public health goals of these programs. These findings should inform state and federal efforts to expand the role of law enforcement in behavioral health initiatives.

Injection Drug Use Frequency Before and After Take-Home Naloxone Training

Importance

Concerns that take-home naloxone (THN) training may lead to riskier drug use (as a form of overdose risk compensation) remain a substantial barrier to training implementation. However, there was limited good-quality evidence in a systematic review of the association between THN access and subsequent risk compensation behaviors.

Objective

To assess whether THN training is associated with changes in overdose risk behaviors, indexed through injecting frequency, in a cohort of people who inject drugs.

Design, Setting, and Participants

This cohort study used prospectively collected self-reported behavioral data before and after THN training of participants in The Melbourne Injecting Drug User Cohort Study (SuperMIX). Annual interviews were conducted in and around Melbourne, Victoria, Australia, from 2008 to 2021. SuperMIX participants were adults who regularly injected heroin or methamphetamine in the 6 months preceding their baseline interview. The current study included only people who inject drugs who reported THN training and had participated in at least 1 interview before THN training.

Exposure

In 2017, the SuperMIX baseline or follow-up survey began asking participants if and when they had received THN training. The first THN training date that was recorded was included as the exposure variable. Subsequent participant interviews were excluded from analysis.

Main Outcomes and Measures

Injecting frequency was the primary outcome and was used as an indicator of overdose risk. Secondary outcomes were opioid injecting frequency, benzodiazepine use frequency, and the proportion of the time drugs were used alone. Fixed-effects generalized linear (Poisson) multilevel modeling was used to estimate the association between THN training and the primary and secondary outcomes. Time-varying covariates included housing status, income, time in study, recent opioid overdose, recent drug treatment, and needle and syringe coverage. Findings were expressed as incidence rate ratios (IRRs) with 95% CIs.

Results

There were 1328 participants (mean [SD] age, 32.4 [9.0] years; 893 men [67.2%]) who completed a baseline interview in the SuperMIX cohort, and 965 participants completed either a baseline or follow-up interview in or after 2017. Of these 965 participants, 390 (40.4%) reported THN training. A total of 189 people who inject drugs had pretraining participant interviews with data on injecting frequency and were included in the final analysis (mean [SD] number of interviews over the study period, 6.2 [2.2]). In fixed-effects regression analyses adjusted for covariates, there was no change in the frequency of injecting (IRR, 0.91; 95% CI, 0.69-1.20; P = .51), opioid injecting (IRR, 0.95; 95% CI, 0.74-1.23; P = .71), benzodiazepine use (IRR, 0.96; 95% CI, 0.69-1.33; P = .80), or the proportion of reported time of using drugs alone (IRR, 1.04; 95% CI, 0.86-1.26; P = .67) before and after THN training.

Conclusions and Relevance

This cohort study of people who inject drugs found no evidence of an increase in injecting frequency, along with other markers of overdose risk, after THN training and supply. The findings suggest that THN training should not be withheld because of concerns about risk compensation and that advocacy for availability and uptake of THN is required to address unprecedented opioid-associated mortality.

How to save a life: Public awareness of a national mass media take home naloxone campaign, and effects of exposure to campaign components on overdose knowledge and responses

BACKGROUND

Take home naloxone (THN) programmes are effective at reducing opioid related mortality, but require high levels of distribution, including to the general public. Mass media campaigns can be effective in improving public understanding of a topic and encouraging behavior change. Whilst mass media campaigns focusing on naloxone have been developed internationally, there is a lack of research on their potential impact. We investigated the effects of components of a recent national mass media campaign (Scotland, UK) designed to improve public awareness of drug related deaths, and readiness to intervene.

METHODS

We undertook a cross-sectional online experimental study with a randomized design, conducted with a nationally representative sample. Participants (N = 1551; 52.6% female; age 46.1±16.5 years) were assessed on overdose knowledge and readiness to intervene after presentation of eight combinations of campaign components.

RESULTS

Compared to a basic campaign description, exposure to all types of campaign component were associated with higher overdose knowledge (p < .001), but not knowledge of what to do in response to an overdose (p = .374), or readiness to intervene (p= .286). The greatest effects were associated with a media rich audio-visual resource (animated video with a popular song on the soundtrack, and narrated by a well-known actor).

CONCLUSION

Our data suggest that harm reduction is an appropriate topic for large-scale mass media campaigns. However, effects may be limited to knowledge and awareness raising in the general public, and may be related to the types of media used. Audience segmentation is important and more general messaging about drug related deaths may be more appropriate for the majority of audiences.

Optimizing buprenorphine training during undergraduate medical education: Medical student feedback and attitudes

BACKGROUND AND OBJECTIVES

Strong evidence supports efficacy of medications for opioid use disorder (MOUD), but stringent prescribing policies impair access. Many physicians report discomfort prescribing MOUD due to inadequate knowledge. Most medical students believe MOUD training should occur during undergraduate medical education (UME). As legislation surrounding buprenorphine prescribing shifts, it is timely to consider how best to incorporate MOUD training into UME.

METHODS

At the start of 3rd year, all students (n = 290) received a survey regarding experiences working with people with OUDs, and beliefs and knowledge regarding harm reduction and treatment. During orientation, students completed an 8-h online MOUD training. Afterwards, students completed another survey, including questions about training perceptions.

RESULTS

One-third of students (32.8%) completed MOUD training and both surveys. Before training, 60.0% had not heard of the waiver, but 82.1% endorsed interest in prescribing buprenorphine. Despite mixed feelings about training content and delivery, 79.1% believed future classes should receive it. Most thought it should be integrated longitudinally throughout the curriculum rather than as separate online training.

CONCLUSION AND SCIENTIFIC SIGNIFICANCE

Medical students want more MOUD education throughout their training; however, the 8-h online training may be less-than-optimal. As this training is no longer required to prescribe buprenorphine, there is an opportunity to modify the content presented. There is an urgent need for physicians with the knowledge and willingness to treat patients with OUD. Introducing integrated training about MOUD should help future physicians feel confident in their knowledge to treat patients and comfortable applying for the waiver.

Preliminary effectiveness of online opioid overdose and naloxone administration training and impact of naloxone possession on opioid use

BACKGROUND

Despite the demonstrated value of opioid overdose education and naloxone distribution (OEND) programs, uptake and utilization remains low. Accessibility to OEND is limited and traditional programs may not reach many high-risk individuals. This study evaluated the effectiveness of online opioid overdose and naloxone administration education and the impact of naloxone possession.

METHODS

Individuals with self-reported illicit use of opioids were recruited via Craigslist advertisements and completed all assessments and education online via REDCap. Participants watched a 20-minute video outlining signs of opioid overdose and how to administer naloxone. They were then randomized to either receive a naloxone kit or be given instructions on where to obtain a kit. Effectiveness of training was measured with pre- and post-training knowledge questionnaires. Naloxone kit possession, overdoses, opioid use frequency, and treatment interest were self-reported on monthly follow-up assessments.

RESULTS

Mean knowledge scores significantly increased from 6.82/9.00 to 8.22 after training (t(194)=6.85, p <0.001, 95% CI[1.00, 1.81], Cohen's d=0.85). Difference in naloxone possession between randomized groups was significant with a large effect size (p <0.001, diff=0.60, 95% CI[0.47, 0.73]). A bidirectional relationship was found between naloxone possession and frequency of opioid use. Overdoses and treatment interest were similar across possession status.

CONCLUSIONS

Overdose education is effective in online video format. Disparity in naloxone possession across groups indicates barriers to obtaining naloxone from pharmacies. Naloxone possession did not influence risky opioid use or treatment interest and its impact on frequency of use warrants further investigation.

Electronic Advisories Increase Naloxone Prescribing Across Health Care Settings

BACKGROUND

Naloxone is a life-saving, yet underprescribed, medication that is recommended to be provided to patients at high risk of opioid overdose.

OBJECTIVE

We set out to evaluate the changes in prescriber practices due to the use of an electronic health record (EHR) advisory that prompted opioid prescribers to co-prescribe naloxone when prescribing a high-dose opioid. It also provided prescribers with guidance on decreasing opioid doses for safety.

DESIGN

This was a retrospective chart abstraction study looking at all opioid prescriptions and all naloxone prescriptions written as emergency department (ED) discharge, inpatient hospital discharge, or outpatient medications, between July 1, 2018, and February 1, 2020. The EHR advisory went live on June 1, 2019.

SUBJECTS

Included in the analysis were all adult patients seen in the abovementioned settings at a large county hospital and associated outpatient clinics.

MAIN MEASURES

We performed an interrupted time series analysis looking at naloxone prescriptions and daily opioid dosing in morphine milligram equivalents (MMEs), before and after initiation of the EHR advisory.

KEY RESULTS

The EHR advisory was associated with changes in prescribers' behavior, leading to increased naloxone prescriptions and decreased prescribed opioid doses.

CONCLUSIONS

EHR advisories are an effective systems-level intervention to enhance the safety of prescribed opioids and increase rates of naloxone prescribing.

Naloxone Co-Dispensing with Opioids: a Cluster Randomized Pragmatic Trial

BACKGROUND

Although naloxone prevents opioid overdose deaths, few patients prescribed opioids receive naloxone, limiting its effectiveness in real-world settings. Barriers to naloxone prescribing include concerns that naloxone could increase risk behavior and limited time to provide necessary patient education.

OBJECTIVE

To determine whether pharmacy-based naloxone co-dispensing affected opioid risk behavior. Secondary objectives were to assess if co-dispensing increased naloxone acquisition, increased patient knowledge about naloxone administration, and affected opioid dose and other substance use.

DESIGN

Cluster randomized pragmatic trial of naloxone co-dispensing.

SETTING

Safety-net health system in Denver, Colorado, between 2017 and 2020.

PARTICIPANTS

Seven pharmacies were randomized. Pharmacy patients (N=768) receiving opioids were followed using automated data for 10 months. Pharmacy patients were also invited to complete surveys at baseline, 4 months, and 8 months; 325 survey participants were enrolled from November 15, 2017, to January 8, 2019.

INTERVENTION

Intervention pharmacies implemented workflows to co-dispense naloxone while usual care pharmacies provided usual services.

MAIN MEASURES

Survey instruments assessed opioid risk behavior; hazardous drinking; tobacco, cannabis, and other drug use; and knowledge. Naloxone dispensings and opioid dose were evaluated using pharmacy data among pharmacy patients and survey participants. Intention-to-treat analyses were conducted using generalized linear mixed models accounting for clustering at the pharmacy level.

KEY RESULTS

Opioid risk behavior did not differ by trial group (P=0.52; 8-month vs. baseline adjusted risk ratio [ARR] 1.07; 95% CI 0.78, 1.47). Compared with usual care pharmacies, naloxone dispensings were higher in intervention pharmacies (ARR 3.38; 95% CI 2.21, 5.15) and participant knowledge increased (P=0.02; 8-month vs. baseline adjusted mean difference 1.05; 95% CI 0.06, 2.04). There was no difference in other substance use by the trial group.

CONCLUSION

Co-dispensing naloxone with opioids effectively increased naloxone receipt and knowledge but did not increase self-reported risk behavior.

TRIAL REGISTRATION

Registered at ClinicalTrials.gov ; Identifier: NCT03337100.

Leveraging Body-Worn Camera Footage to Better Understand Opioid Overdoses and the Impact of Police-Administered Naloxone

Objectives. To investigate what transpires at opioid overdoses where police administer naloxone and to identify the frequency with which concerns about police-administered naloxone are observed. Methods. We reviewed body-worn camera (BWC) footage of all incidents where a Tempe, Arizona police officer administered naloxone or was present when the Tempe Fire Medical Rescue (TFMR) administered it, from February 3, 2020 to May 7, 2021 (n = 168). We devised a detailed coding instrument and employed univariate and bivariate analysis to examine the frequency of concerns regarding police-administered naloxone. Results. Police arrived on scene before the TFMR in 73.7% of cases. In 88.6% of calls the individual was unconscious when police arrived, but 94.6% survived the overdose. The primary concerns about police-administered naloxone were rarely observed. There were no cases of improper naloxone administration or accidental opioid exposure to an officer. Aggression toward police from an overdose survivor rarely occurred (3.6%), and arrests of survivors (3.6%) and others on scene (1.2%) were infrequent. Conclusions. BWC footage provides a unique window into opioid overdoses. In Tempe, the concerns over police-administered naloxone are overstated. If results are similar elsewhere, those concerns are barriers that must be removed. (Am J Public Health.

Beliefs and misperceptions about naloxone and overdose among U.S. laypersons: a cross-sectional study

BACKGROUND

Overdose education and naloxone distribution (OEND) to laypersons are key approaches to reduce the incidence of opioid-involved overdoses. While some research has examined attitudes toward OEND, especially among pharmacists and first responders, our understanding of what laypersons believe about overdose and naloxone is surprisingly limited. Further, some scholars have expressed concerns about the prevalence of non-evidence-based beliefs about overdose and naloxone. We designed this study to analyze the prevalence, nature, and context of beliefs about naloxone and overdose among U.S. laypersons.

METHODS

We conducted a cross-sectional study (n = 702) using Prolific.co (representative of the U.S. population by age, gender, and race). Primary outcomes were the believability of six statements about overdose/naloxone on a seven-point Likert-type scale. Five statements were unsupported, and one was supported, by current scientific evidence. We used latent profile analysis to classify participants into belief groups, then used regression to study correlates of profile classification.

RESULTS

Believability of the statements (7: extremely believable) ranged from m = 5.57 (SD = 1.38) for a scientifically supported idea (trained bystanders can reverse overdose with naloxone), to m = 3.33 (SD = 1.83) for a statement claiming opioid users can get high on naloxone. Participants were classified into three latent belief profiles: Profile 1 (most aligned with current evidence; n = 246), Profile 2 (moderately aligned; n = 351), and Profile 3 (least aligned, n = 105). Compared to Profile 1, several covariates were associated with categorization into Profiles 2 and 3, including lower trust in science (RRR = 0.36, 95%CI = 0.24-0.54; RRR = 0.21, 95%CI = 0.12-0.36, respectively), conservative political orientation (RRR = 1.41, 95%CI = 1.23-1.63; 3:RRR = 1.62, 95%CI = 1.35-1.95, respectively), and never being trained about naloxone (Profile 3: RRR = 3.37, 95%CI = 1.16-9.77).

CONCLUSIONS

Preliminary evidence suggests some U.S. laypersons simultaneously believe that bystander overdose prevention with naloxone can prevent overdose and one or more scientifically unsupported claims about naloxone/overdose. Categorization into clusters displaying such belief patterns was associated with low trust in science, conservative political orientation, and not having been trained about naloxone.

Stigma by Association: To what Extent is the Attitude Toward Naloxone Affected by the Stigma of Opioid Use Disorder?

The United States opioid epidemic is fueled by illicit opioid abuse and prescription opioid misuse and abuse. Consequently, cases of opioid use disorder (OUD, opioid addiction), opioid overdose, and related deaths have increased since the year 2000. Naloxone is an opioid antagonist that rapidly reverses opioid intoxication to prevent death from overdose. It is one of the major risk mitigation strategies recommended in the 2016 Centers for Disease Control and Prevention Guideline for Prescribing Opioids for Chronic Pain. However, despite the exponential increase in dispensing and distribution of naloxone, opioid overdose and related deaths have continued to increase; suggesting that the increased naloxone supply still lags the need. This discordance is attributed at least in part to the negative attitude toward naloxone, which is based on the belief that naloxone is only meant for "addicts" and "abusers" (OUD patients). This negative attitude or so-called naloxone stigma is therefore considered a major barrier for naloxone distribution and consequently, overdose-death prevention efforts. This article presents evidence that challenges common assertions about OUD stigma being the sole and direct driving force behind naloxone stigma, and the purported magnitude of the barrier that naloxone stigma constitutes for naloxone distribution programs among the stakeholders (patients, pharmacists, and prescribers). The case was then made to operationalize and quantify the construct among the stakeholders to determine the extent to which OUD stigma drives naloxone stigma, and the relative impact of naloxone stigma as a barrier for naloxone distribution efforts.

The Overdose Response with Take Home Naloxone (ORTHN) project: Evaluation of health worker training, attitudes and perceptions

INTRODUCTION

Naloxone is a life-saving medication that reverses opioid overdose; naloxone can be provided on a 'take-home' basis so naloxone can be administered outside of the health-care setting. The Overdose Response and Take Home Naloxone (ORTHN) project established a model of care for take-home naloxone (THN) interventions across alcohol and other drug and harm reduction services in NSW, Australia. This paper evaluates the staff training and credentialing program, and examines staff attitudes and perspectives regarding the provision of THN interventions in these settings.

METHODS

Staff across seven services were trained through a 'train-the-trainer' credentialing model to deliver ORTHN, including naloxone supply. Staff were surveyed regarding their experience, attitudes and knowledge on THN prior to and after training, and after 6 months. At the 6 months follow up, staff were asked about the interventions they provided, barriers and enablers to uptake, and opinions regarding future rollout.

RESULTS

A total of 204 staff were trained and credentialed to provide the ORTHN intervention. Most (60%) were nurses, followed by needle syringe program workers and allied health/counsellors (32%). Linear and logistic regression analyses indicated that the training program was associated with significant improvements in staff knowledge and attitudes towards overdose and THN; however, only attitudinal improvements were maintained over time. There were high rates of staff satisfaction with the ORTHN intervention and training.

DISCUSSION/CONCLUSIONS

The ORTHN program is 'fit for purpose' for broad implementation in these settings. A number of potential barriers (e.g. time, medication and staffing costs) and enablers (e.g. peer engagement, regulatory framework for naloxone supply) in implementing THN interventions were identified.

Perspectives from law enforcement officers who respond to overdose calls for service and administer naloxone

BACKGROUND

Many law enforcement agencies across the United States equip their officers with the life-saving drug naloxone to reverse the effects of an opioid overdose. Although officers can be effectively trained to administer naloxone, and hundreds of law enforcement agencies carry naloxone to reverse overdoses, little is known about what happens on scene during an overdose call for service from an officer's perspective, including what officers perceive their duties and responsibilities to be as the incident evolves.

METHODS

The qualitative study examined officers' experiences with overdose response, their perceived roles, and what happens on scene before, during, and after an overdose incident. In-person interviews were conducted with 17 officers in four diverse law enforcement agencies in the United States between January and May 2020.

RESULTS

Following an overdose, the officers described that overdose victims are required to go to a hospital or they are taken to jail. Officers also described their duties on scene during and after naloxone administration, including searching the belongings of the person who overdosed and seizing any drug paraphernalia.

CONCLUSION

These findings point to a pressing need for rethinking standard operating procedures for law enforcement in these situations so that the intentions of Good Samaritan Laws are upheld and people get the assistance they need without being deterred from asking for future help.

Perspectives of Stakeholders of Equitable Access to Community Naloxone Programs: A Literature Review

The purpose of this review is to examine the existing literature about facilitators and barriers influencing equitable access to naloxone programs by individuals who use opioids. A total of 49 published articles were examined, which generated four overarching themes:(1) Stigma as a barrier to access; (2) Lack of a wide range of stakeholder perspectives; (3) Need for a comprehensive understanding of factors affecting equitable access to naloxone programs; (4) Facilitators to increase the access of community naloxone programs. Our review highlighted the importance of advocacy in practice, education, administration, and policy to address the health inequities that exist in naloxone distribution programs. Advocacy activities involve the need for health care professionals to engage in social justice practice through evidence-based informed research about the facts of opioid use; challenging the stigma toward victim-blaming against naloxone users; as well as promoting program development and health policy to bring about equitable access to naloxone programs by marginalized and socially disadvantaged populations.

Training medical students in opioid overdose prevention and response: Comparison of In-Person versus online formats

Medical education has increasingly shifted towards replacing large lectures with a combination of online and smaller in-person group sessions. This study compares the efficacy of a virtual Opioid Overdose Prevention and Response Training (OOPRT) for first-year medical students with an identical in-person training. During their first unit of medical school, students in the class of 2023 (cohort 1) received OOPRT in-person and students in the class of 2024 (cohort 2) received training via Zoom. Aside from the delivery format, trainings were identical. Both cohorts completed identical surveys at medical school entry and post-training to evaluate knowledge and experiences using the Opioid Overdose Knowledge Scale, Opioid Overdose Attitudes Scale, Medical Conditions Regard Scale, and Naloxone Related Risk Compensation Beliefs. Of 430 students, 84.2% (362: 124 in cohort 1; 238 in cohort 2) completed baseline and post-training surveys. Students reported significantly improved opioid overdose knowledge and attitudes in all 4 knowledge and 3 attitudes subscales after training. Only one outcome differed by training type: knowledge of opioid overdose signs. Cohorts did not differ in opinions of training; 97.2% enjoyed it and 99.4% believed future classes should receive it. Medical students' attitudes and knowledge significantly improved after OOPRT; only one of 13 outcomes showed a cohort difference. There were no differences in enjoyment, indicating that switching to virtual learning does not undermine the learning experience. Further studies are needed to confirm that these results can be extended to other medical school topics where small group interactive discussion is preferred.

Does naloxone provision lead to increased substance use? A systematic review to assess if there is evidence of a 'moral hazard' associated with naloxone supply

BACKGROUND

Take home naloxone (THN) programs have been rapidly upscaled in response to increasing opioid-related mortality. One often cited concern is that naloxone provision could be associated with increased opioid use, due to the availability of naloxone to reverse opioid overdose. We conducted a systematic review to determine whether THN provision is associated with changes in substance use by participants enrolled in THN programs.

METHODS

We conducted a systematic review of the literature to assess changes in heroin or other substance use by people who use opioids following THN provision.

RESULTS

Seven studies with 2578 participants were included. Of the seven studies, there were two quasi-experimental studies and five cohort studies. Based on the Joanna Briggs Institute quality assessment, four studies were of moderate quality and three studies were of high quality. Of the five studies that reported on the primary outcome of heroin use, no study found evidence of increased heroin use across the study population. Five studies reported on other substance use (benzodiazepines, alcohol, cocaine, amphetamine, cannabis, prescription opioids), none of which found evidence of an increase in other substance use associated with THN provision. Four studies reported on changes in overdose frequency following THN provision: three studies reporting no change, and one study of people prescribed opioids finding a reduction in opioid-related emergency department attendances for participants who received naloxone.

CONCLUSION

We found no evidence that THN provision was associated with increased opioid use or overdose. Concerns that THN supply may lead to increased substance use were not supported by data from reviewed studies.

Naloxone's role in the national opioid crisis-past struggles, current efforts, and future opportunities

Over the past 25 years, naloxone has emerged as a critical lifesaving overdose antidote. Public health advocates and community activists established early methods for naloxone distribution to people who inject drugs, but a legacy of stigmatization and opposition to universal naloxone access continues to limit the drug's full potential to reduce opioid-related mortality. The establishment of naloxone distribution programs under the umbrella of syringe exchange programs faces the same practical, ideological and financial barriers to expansion similar to those faced by syringe exchange programs themselves. The expansion of naloxone from the confines of a few syringe exchange programs to what we see today represents an enormous triumph for the grass-roots activists, service providers, and public health professionals who have fought to guarantee lay access to naloxone. Despite the extensive efforts to expand access to naloxone, naloxone continues to remains a scarce resource in many US localities. Considerable naloxone "deserts" remain and even where there is naloxone access, it does not always reach those at risk. Promising areas for expansion include the development of more robust telehealth methods for naloxone distribution, including subsidized mail delivery programs; lowering barriers to pharmacy access; working with hospitals, ambulances, and law enforcement to expand naloxone "leave behind" programs; providing naloxone co-prescription with medications for opioid use disorder; and working with prisons, shelters, and networks of people who use drugs to increase access to the lifesaving medication. Efforts to ensure over-the-counter and low- or no-cost naloxone are ongoing and stand alongside medication-assisted treatments as efficacious, readily-actionable, and cost-efficient population-level interventions available for combatting opioid-related overdose in the United States.

Moving Beyond Narcan: A Police, Social Service, and Researcher Collaborative Response to the Opioid Crisis

The opioid crisis is the most persistent, long-term public health emergency facing the United States, and available evidence suggests the crisis has worsened during the COVID-19 global pandemic. Naloxone is an effective overdose response that saves lives, but the drug does not address problematic drug use, addiction, or the underlying conditions that lead to overdoses. The opioid crisis is at its core a multidisciplinary, multisystem problem, and an effective response to the crisis requires collaboration across those various systems. This paper describes such a collaborative effort. The Tempe First-Responder Opioid Recovery Project is a multidisciplinary partnership that includes police officers, social workers, substance use peer counselors, public health professionals, police researchers, and drug policy/harm reduction researchers. The project, 10 months underway, trained and equipped Tempe (AZ) police officers to administer Narcan. In addition, a 24/7 in-person "Crisis Outreach Response Team" rapidly responds to any suspected overdose and offers follow-up support, referrals, and services to the individual (and loved ones) for up to 45 days after the overdose. We present preliminary project data including interviews with project managers, counselors, and police officers, descriptions of Narcan administrations in the field, and aggregate data on client service engagement. These data highlight the complexity of the opioid crisis, the collaborative nature of the Tempe project, and the importance of initiating a multidisciplinary, comprehensive response to effectively deal with the opioid problem.

Developing and validating an opioid overdose prevention and response curriculum for undergraduate medical education

Introduction: As rates of overdose and substance use disorders (SUDs) increase, medical schools are starting to incorporate more content on SUDs and harm reduction in undergraduate medical education (UME). Initial data suggest these additions may improve medical student knowledge and attitudes toward patients with SUDs; however, there is no standard curriculum. Methods: This project uses a six-step approach to UME curricular development to identify needs and goals regarding SUDs and opioid overdose at a large single-campus medical school in the United States. We first developed and delivered a pilot curriculum to a small group of medical students. Pilot results and a larger survey led to implementing a one-hour Opioid Overdose Prevention and Response (OOPR) Training for first-year students. Effects of training were tracked using baseline and post-training surveys examining knowledge and attitudes toward opioid overdose and patients with SUDs. Results: Needs assessment indicated desire and need for training. The pilot study (N = 66) resulted in significantly improved knowledge regarding opioid overdose; 100% of students enjoyed training and believed others should receive it. The larger replication study surveyed all incoming students (N = 266) to gauge initial knowledge and experiences with these topics. Results prompted enhancement of the OOPR Training curriculum, which was delivered to half of the first-year class. Post-training survey results replicated the pilot study findings. The majority (95.2%) of students enjoyed training and 98.4% believed all students should receive it. Conclusion: Delivering a thorough curriculum on SUDs and harm reduction in UME is critical. Although many schools are implementing training, there is no standard curriculum. We outline a low-resource training intervention for OOPR. Our findings identified key features to include in these UME curricula. This approach provides a replicable template for schools seeking to develop brief educational interventions and identify essential content for curricula in SUDs and harm reduction.
