Harm reduction in the Heartland: public knowledge and beliefs about naloxone in Nebraska, USA

Effectiveness of naloxone distribution in community settings to reduce opioid overdose deaths among people who use drugs: a systematic review and meta-analysis

BACKGROUND

It is estimated that over 111,000 people in the U.S. died from a drug overdose in the twelve-month period ending in July 2023. More than three-quarters of those deaths were attributed to opioids. Naloxone has long been available in healthcare facilities to reverse opioid overdose rapidly and safely but is not universally accessible for use in community settings where overdoses occur. We conducted a systematic literature review and meta-analysis to assess the effectiveness of overdose education and naloxone distribution (OEND) programs in three types of community settings to reduce overdose deaths among people who use opioids nonmedically.

METHODS

We systematically searched electronic databases, including Medline (OVID), Embase (OVID), Psycinfo (OVID), and Global Health (OVID), for peer-reviewed studies of OEND programs published during 2003-2018 (Group 1) that reported overdose outcomes individual level survivals or deaths immediately following naloxone administration. The PRISMA checklist guided screening, quality assessment, and data abstraction. We later identified studies published during 2018-2022 (Group 2), when drug usage and fentanyl-related overdose deaths notably increased, differed from earlier ones. We conducted meta-analyses on both Groups using random effects models to estimate summary survival proportions.

RESULTS

Among the 44 Group 1 studies published during 2003-2018, survival did not differ by time (year), location, naloxone dose, or route of administration, but studies of OEND programs serving people who use drugs reported 98.3% (95% CI: 97.5-98.8) survival; those serving family of people who use drugs or other community members reported 95.0% (95% CI: 91.4-97.1) survival; and those for police reported 92.4% (95% CI: 88.9-94.8) survival (p < 0.01). Five Group 2 studies (2018-2022) yielded similar results.

CONCLUSIONS

Community-based naloxone distribution programs can be effective in preventing opioid overdose deaths. The paper demonstrates that in the face of increasing overdose deaths over time, survival after naloxone administration has been sustained. The very high survival rates provide clear evidence for public health to continue efforts to expand channels for naloxone distribution in community settings.

An interrupted time series analysis of fentanyl, naloxone, and opioid-involved deaths in five counties in Eastern Missouri

INTRODUCTION

Rates of opioid overdose deaths (OOD) have increased since the introduction of illicitly manufactured fentanyl in the U.S. drug supply. Though community-based naloxone distribution efforts have been found to effectively reduce OOD, no studies to date have examined their effects during the fentanyl era, nor in the epicenter of a state's overdose crisis. Thus, the current study assessed the impacts of both fentanyl and of subsequent grant-funded community-based naloxone distribution on OOD across Missouri's St. Louis region.

METHODS

Medical examiner data includes individuals who died within one of the five study counties (St. Louis City, St. Louis County, and Franklin, Jefferson, St. Charles counties [combined as "Collar Counties"]) between 2011 and 2022 due to an opioid overdose (N = 6,799). Naloxone distribution date and location data came from Missouri's university-based naloxone distribution team. We conducted a controlled interrupted time series using an autoregressive model via proc ARIMA to examine changes over time in the rate of OOD associated with the introduction of fentanyl (defined to be present in 25% of opioid overdose deaths; June 2015) and the start of naloxone distribution for each location (August 2017, October 2017, and January 2018, respectively).

RESULTS

The introduction of fentanyl into the drug supply of St. Louis City was associated with an increased rate of OOD over time (p < .001). Naloxone distribution in the City was associated with an immediate decrease in OOD (p < .001) followed by a slowed increase in OOD (p < .001). These findings were not replicated in St. Louis County nor the Collar Counties.

CONCLUSIONS

The effects of fentanyl and naloxone on OOD varied by region in Eastern Missouri. Specifically, fentanyl and naloxone effects were only found in a high-need urban area with existing harm reduction and street outreach programs, but not in surrounding suburban or rural areas. State-level naloxone distribution decision-makers should prioritize funding harm reduction services in both urban and non-urban settings to help increase targeted naloxone distribution to those actively using drugs. Additionally, interventions tailored for people who engage in solitary drug use - such as safe consumption spaces and overdose detection technologies - should receive increased investment and implementation, particularly in rural areas where harm reduction infrastructure is more scarce.

Naloxone Stigma Among People Who Use Drugs: Characteristics and Associations With Stigma Toward Medication for Opioid Use Disorder

OBJECTIVES

Widespread naloxone distribution is key to mitigating opioid-related morbidity, but stigma remains a barrier. Naloxone stigma among providers, emergency responders, and the public is well-documented and associated with treatment and policy preferences, but little is known about naloxone stigma among people who use drugs (PWUD), who may be overdose first responders. This study examines naloxone stigma, its correlates, and its association with stigma toward medication for opioid use disorder (MOUD) among PWUD.

METHODS

We recruited 293 individuals with a history of substance misuse from facilities that provide substance use and/or health care services (retained n = 195, 54% women, 75% White). Participants completed self-report measures, including the 5-item Naloxone-Related Risk Compensation Beliefs scale.

RESULTS

One in 5 respondents agreed with beliefs that access to naloxone leads to more opioid use and less treatment seeking and is "enabling." Those with nonopioid drug misuse, without prior overdose, and with fewer recovery attempts endorsed more naloxone stigma. Opioid misuse, prior overdose, and MOUD utilization were also inversely associated with MOUD stigma. There were no demographic differences in either stigma type. Naloxone stigma was positively associated with MOUD stigma in adjusted models.

CONCLUSIONS

This is the first study to quantitatively examine naloxone stigma among PWUD. Findings emphasize the potential role of overdose education and naloxone distribution among those earlier in the substance use disorder course and who use nonopioid drugs. They support integrating MOUD stigma interventions into current overdose education and naloxone distribution targeted at PWUD to increase the acceptance and uptake of both medications.

State program enables the identification of factors associated with naloxone awareness, self-efficacy, and use for overdose reversal: A cross-sectional, observational study in an urban emergency department population

INTRODUCTION

To assist the state of Ohio in addressing the opioid epidemic, the Ohio Attorney General appointed experts in a variety of academic disciplines to the Scientific Committee on Opioid Prevention and Education (SCOPE). The focus of SCOPE is the application of scientific principles to the development of prevention and educational strategies for reducing substance use disorder and related harms (e.g., promoting naloxone awareness). Naloxone awareness is a step in the naloxone cascade, which is a useful model for understanding the sequential steps laypeople must take to prepare themselves to intervene using naloxone; other steps include training and previous administration experience. Prior work has explored correlates of these steps among individuals with risky substance use, but fewer studies have focused on broader populations containing potential bystanders (e.g., family and community members).

METHODS

This study was a secondary data analysis of patients from three urban emergency departments. Subsamples differed across five models (n = 479-1208) and included opioid-exposed and -naïve participants. Logistic regression characterized clinically useful sociodemographic predictors (e.g., race, ethnicity, education, employment, housing status) of naloxone awareness, self-efficacy (which relates to training), and previous-overdose administration. Two additional logistic regressions tested associations between risk factors for witnessing an opioid overdose and two cascade steps (awareness and self-efficacy).

RESULTS

Non-White race, Hispanic ethnicity, and lower education predicted not being aware of naloxone; non-White race also predicted lower naloxone self-efficacy, and older age predicted lack of previous-overdose administration. Having family members with risky opioid use was heavily associated with awareness, while personal substance-use behaviors and previous overdose witnessing were associated with both awareness and higher naloxone self-efficacy.

CONCLUSIONS

Characteristics associated with lower likelihood of completing each cascade step highlight opportunities for targeted interventions. Specifically, findings indicated the importance of expanding naloxone education and training programs to more diverse populations and to family members of individuals with risky opioid use. Further, these findings demonstrate how a state-funded program such as SCOPE can have a positive impact on identifying strategies that may assist in reducing mortality associated with opioid overdose.

Factors associated with gaps in naloxone knowledge: evidence from a 2022 great plains survey

BACKGROUND

The rising prevalence of fast-acting opioids in the USA suggests the increased need for non-professional first responder administration of naloxone. Effective administration of naloxone during an overdose requires that bystanders are familiar with, have access to, and know how to use naloxone.

METHODS

Drawing on a statewide, address-based sample of Nebraskan adults, we used logistic regression to predict the likelihood of respondents' familiarity with, access to, and competency to administer naloxone. Our independent variables included measures indicating proximity to drug use, perceived community stigma toward people who use drugs, and demographic data.

RESULTS

There were significant gaps in naloxone knowledge in Nebraska. Although 74.8% of respondents were familiar with naloxone, only 18.2% knew how to access it and 18.0% knew how to use it. Being close to an overdose experience, lifetime illicit opioid use, being close to a person who uses opioids, and having access to illicit opioids were not significantly associated with naloxone familiarity, access, or competency among respondents in Nebraska's two largest cities, Omaha and Lincoln. Outside of these cities, being close to a past overdose experience and access to illicit opioids was associated with higher odds of naloxone access and competency, but lifetime opioid use and being close to a person who uses opioids were not. Finally, among those familiar with naloxone, a higher perception of community stigma toward people who use opioids generally was associated with lower odds of naloxone access and competency. Higher perception of community stigma toward people who use heroin, methamphetamines, and cocaine, however, was associated with higher odds of naloxone access.

CONCLUSIONS

Our findings highlight the continued need for education on naloxone with a specific focus on access and competency to further reduce opioid-related overdose deaths. Specific focus should be placed on promoting naloxone knowledge among people with a higher likelihood of needing to administer naloxone to reduce otherwise avoidable deaths. Further work is needed to understand differences in the relationship between substance-specific perceived stigma and its association with naloxone access.

Stigma as a local process: Stigma associated with opioid dependency in a rural-mixed Indiana county

BACKGROUND

Because the nature and magnitude of stigmatizing views associated with opioid dependency vary by social, cultural, and structural factors, strategies to reduce public stigma towards opioid dependency should vary by context. We leverage a unique dataset with evidence of multiple stigmatizing views to understand how to target interventions to reduce stigma in a state disproportionately impacted by the opioid epidemic, with a specific focus on a rural-mixed county.

METHODS

Data come from the representative Person-to-Person Health Study (2018-2020) of 2,050 Indiana residents, 224 from the rural-mixed Fayette County. Bivariate statistics and multivariate regression analyses were used to evaluate the association between Fayette County and measures of stigma (e.g., desire for social distance, prejudice, causal attributions) relative to the rest of Indiana.

RESULTS

Fayette County statistically differed from the rest of Indiana on most demographic characteristics and measures of stigmatizing views. Multivariate regressions revealed that compared to the rest of Indiana, residence in Fayette County was associated with a higher desire for social distance, perceptions of unpredictability, and attributing opioid dependency to genetics and the way the person was raised.

CONCLUSION

Our results contribute to growing evidence supporting the need for local approaches to address stigma. Stigma in Fayette County primarily reflects concerns about how people manage their opioid dependency. Strategies focusing on treatment and recovery potential, accompanied by extending the influence of supportive stakeholders and policies, will become important to address this stigma.

Factors Associated with Gaps in Naloxone Knowledge: Evidence from a 2022 Great Plains Survey

Background

The rising prevalence of fast-acting opioids in the United States suggests the increased need for non-first responder administration of naloxone. Effective administration of naloxone during an overdose requires that bystanders are familiar with, have access to, and know how to use naloxone.

Methods

Drawing on the 2022 Nebraska Annual Social Indicators survey, we analyzed naloxone familiarity, access, and competency to administer among a statewide, address-based sample of Nebraskan adults.

Results

There were significant gaps in naloxone knowledge in Nebraska. Although 75.6% of respondents were familiar with naloxone, only 18.6% knew how to access naloxone and 17.6% knew how to use naloxone. We find that more frequent religious service attendance is associated with lower odds of naloxone familiarity. Among those familiar with naloxone, a higher perception of community stigma towards opioids generally is associated with lower odds of naloxone access and competency. Higher perception of community stigma towards heroin, methamphetamines, and cocaine, however, is associated with higher odds of naloxone access. Finally, past overdose experience, lifetime illicit opioid use, being close to a person who uses opioids, and having access to illicit opioids was not significantly associated with naloxone familiarity, access, or competency among respondents in Nebraska's two largest cities, Omaha and Lincoln. Outside of these cities, past overdose experience and access to illicit opioids was associated with higher odds of naloxone access and competency, but lifetime opioid use and being close to a person who uses opioids had no effect.

Conclusions

Our findings highlight the continued need for education on naloxone with a specific focus on access and competency to further reduce opioid-related overdose deaths. Education campaigns targeted at places of worship or individuals close to people who use opioids may further serve those with a lower likelihood of naloxone familiarity and promote knowledge of naloxone among those with higher odds of encountering an overdose. Further work is needed to understand differences in the relationship between substance-specific perceived stigma and its association with naloxone access.

Opioid Use Disorder Stigma and Support for Harm Reduction in Rural Counties

Background: The opioid crisis is a public health emergency in the United States, particularly in rural Pennsylvania. Stigma in rural communities is a treatment barrier and impacts harm reduction programming availability.Objectives: The current study utilized an observational, cross-sectional design to examine latent subgroups of stigma and differences in support for harm reduction strategies (i.e., safe injection facilities, syringe services programs, fentanyl test strips, Naloxone distribution). Participants included rural Pennsylvanians (n = 252), taken from a statewide survey of opioid use disorder (OUD) stigma. Participants reported OUD public stigma (i.e., attitudes/perceptions about OUD, willingness to engage with individuals with OUD) and support for harm reduction strategies.Results: Latent class analysis identified 4 stigma classes: 1) high stigma (HS), 2) high judgment/low stigmatizing behavior (HJ/LB), 3) high stigmatizing behavior/low stigmatizing attitude (HB/LA), and 4) low stigma (LS). ANCOVAs identified subgroup differences in harm reduction support. The HS group indicated less support for safe injection sites, syringe services programs, and fentanyl test strips, compared to the HB/LA and LS groups. The HS group indicated less support for Naloxone distribution compared to the HJ/LB, HB/LA, and LS groups. Lastly, the HJ/LB group indicated less support for each program compared to the LS group.Conclusions/Importance: Findings highlight that OUD stigma profiles differ across rural Pennsylvania and are associated with varying support for harm reduction strategies. Individuals with less stigma report more support for harm reduction strategies. Interventions to implement harm reduction strategies should consider varying levels of stigma and use a targeted approach to inform implementation and messaging strategies.

A multi-site intervention using influencers to communicate about syringe service programmes

Introduction

In the USA, syringe services programmes (SSPs) provide a range of harm reduction services and have numerous benefits for communities. However, stigma, misconceptions about SSPs and changing policies/legislation remain a challenge to effective implementation. This study reviews the implementation of two digital interventions, Appalachian Influence and Shared Influence, which used social media influencers and digital volunteers to communicate positive information about harm reduction and SSPs.

Methods

The intervention was designed to deliver accurate and supportive messaging in locally relevant and meaningful ways. Messaging was informed by interviews with subject matter experts and community organisations, and was integrated into prompts used by local influencers (paid individuals with more than 1,000 followers) and digital volunteers (unpaid individuals with no following requirement, who joined the project independently).

Results

In the first 6 months of implementation, Appalachian Influence and Shared Influence engaged a total of 9,014 individuals, 236 of whom were paid influencers and 8,778 of whom were digital volunteers. Paid influencer posts achieved a total of 868,943 impressions, 42,432 engagements and 1,567 comments. Comments on paid influencer posts were overwhelmingly positive, with 87.4% positive and 0.8% negative. Interviews showed the importance of understanding local realities, leading with compassion and emphasising the 'human' aspects of dependency and addiction in messaging.

Conclusion

This study shows the potential to implement an influencer-led social media intervention to reach people with authentic and compassionate messaging about harm reduction and SSPs. Future research should examine intervention effectiveness and how this approach can be applied to other stigmatised topics.

Public Perceptions of Community Pharmacy-Based Naloxone Services: A National Cross-Sectional Survey

Little is known about the general public's perceptions regarding community pharmacist-delivered naloxone services at the national level. Accordingly, the purpose of this study was to describe the US general public's awareness, knowledge, beliefs, comfort, perceived barriers, abilities, and communication preferences related to community pharmacy-based naloxone services. A national, online cross-sectional survey was conducted in September 2021 among US adults ≥18 years recruited via Amazon Mechanical Turk (MTurk). Primary outcome measures were assessed via 5-point Likert-type scales, including: (1) naloxone awareness and knowledge; (2) naloxone beliefs; (3) comfort with pharmacist-provided naloxone; (4) perceived barriers to pharmacy-based naloxone; (5) opioid overdose competencies, concerns, and readiness; and (6) preferred pharmacist-patient naloxone communication strategy. Analyses included descriptive statistics and logistic regression models to assess predictors of preferred communication strategies. Of 301 respondents, 82.1% were White, 48.8% female, and mean 43 years. Eighty-five percent were unaware of pharmacy-provided naloxone and mean [SD] knowledge score was low (29.3% [16.8]). Mean [SD] beliefs (3.78 [0.61]) and comfort (3.70 [0.54]) were positive, while perceived barriers were low/neutral (2.93 [0.78]). For communication, 54% preferred general advertisement, 32.9% universal offer, and 13.3% targeted offer. The odds of preferring a general advertisement or universal offer over a targeted offer increased with greater awareness (AOR:4.52; p = 0.003) and comfort (AOR:3.79; p = 0.003), and decreased with greater competence (AOR:0.35; p = 0.001). Although awareness and knowledge regarding community pharmacy-based naloxone services was low, beliefs and comfort were positive and perceived barriers were low/neutral. General or universal offers of naloxone were preferred over targeted approaches. Future studies should test the impact of communication strategies on naloxone uptake.

First Responders' Views of Naloxone: Does Stigma Matter?

BACKGROUND

Prior work has suggested that first responders have mixed feelings about harm reduction strategies used to fight the opioid epidemic, such as the use of naloxone to reverse opioid overdose. Researchers have also noted that provider-based stigma of people who use opioids (PWUO) may influence perceptions of appropriate interventions for opioid use disorder (OUD). This study examined first responders' perceptions of naloxone and the relationship between stigma of OUD and perceptions of naloxone.

METHODS

A web-based survey assessing perceptions of PWUO and naloxone was administered to 282 police officers and students enrolled in EMT and paramedic training courses located in the Northeastern United States. Bivariate and multivariable analyses assessed the relationship between variants of stigma (e.g., perceived dangerousness, blame, social distance, and fatalism) and self-reported perceptions of naloxone.

RESULTS

Participants, in the aggregate, held slightly negative attitudes toward the use of naloxone. Findings from multivariable modeling suggest that stigma of OUD, living in a rural area, and prior experience administering naloxone, were significantly and inversely related to support for the use of naloxone. Support for the disease model of addiction and associating drug use with low socioeconomic status were positively related to support for the use of naloxone.

CONCLUSION

Efforts to alleviate perceptions of PWUO as dangerous, blameworthy, or incapable of recovery may increase first responders' support for naloxone. To this end, first responder training programs should include instruction on the disease model of addiction, and more broadly, attempt to foster familiarity between PWUO and the professionals who serve them.
