How do naloxone-based interventions work to reduce overdose deaths: a realist review

Use of harm reduction strategies by individuals with a history of incarceration: A short report using baseline data collected from the STAMINA clinical trial

BACKGROUND

Due to the considerably heightened risk of overdose immediately following jail or prison release, expansion of harm reduction interventions for citizens returning to the community after an incarceration episode should be of utmost concern. However, there are no studies examining the adoption and use of harm reduction among this population. This short report examines the use of individual-level harm reduction strategies (HRS) among people who use drugs, comparing those who have lifetime histories of incarceration with those who do not.

METHODS

This study included baseline data (N = 274) from a larger clinical trial, which recruited participants at two syringe service programs. Fisher's exact tests examine correlations between HRS and lifetime incarceration.

RESULTS

Significant variation in HRS use were observed by demographic characteristics. Those with lifetime incarceration histories were less likely to report ensuring naloxone was available when using, using when others were present, using fentanyl test strips, using a trusted drug supplier, and using some other HRS compared to those without lifetime incarceration histories. Similarly, those with lifetime incarceration histories were also less likely to report using non-prescribed buprenorphine and methadone, which could potentially reduce overdose risk even if not explicitly used as an HRS.

CONCLUSION

The results suggest that one of the populations at highest risk of overdose is least likely to use strategies that may reduce overdose risk. Targeted efforts to increase exposure to HRS learning opportunities and access to these resources could help reduce overdose disparities for people returning to the community after incarceration.

Implementation and Evaluation of a Bystander Naloxone Training Course

Introduction

Bystander provision of naloxone is a key modality to reduce opioid overdose-related death. Naloxone training courses are available, but no standardized program exists. As part of a bystander empowerment course, we created and evaluated a brief naloxone training module.

Methods

This was a retrospective evaluation of a naloxone training course, which was paired with Stop the Bleed training for hemorrhage control and was offered to administrative staff in an office building. Participants worked in an organization related to healthcare, but none were clinicians. The curriculum included the following topics: 1) background about the opioid epidemic; 2) how to recognize the signs of an opioid overdose; 3) actions not to take when encountering an overdose victim; 4) the correct steps to take when encountering an overdose victim; 5) an overview of naloxone products; and 6) Good Samaritan protection laws. The 20-minute didactic section was followed by a hands-on session with nasal naloxone kits and a simulation mannequin. The course was evaluated with the Opioid Overdose Knowledge (OOKS) and Opioid Overdose Attitudes (OOAS) scales for take-home naloxone training evaluation. We used the paired Wilcoxon signed-rank test to compare scores pre- and post-course.

Results

Twenty-eight participants completed the course. The OOKS, measuring objective knowledge about opioid overdose and naloxone, had improved scores from a median of 73.2% (interquartile range [IQR] 68.3%-79.9%) to 91.5% (IQR 85.4%-95.1%), P < 0.001. The three domains on the OOAS score also showed statistically significant results. Competency to manage an overdose improved on a five-point scale from a median of 2.5 (IQR 2.4-2.9) to a median of 3.7 (IQR 3.5-4.1), P < 0.001. Concerns about managing an overdose decreased (improved) from a median of 2.3 (IQR 1.9-2.6) to median 1.8 (IQR 1.5-2.1), P < 0.001. Readiness to intervene in an opioid overdose improved from a median of 4 (IQR 3.8-4.2) to a median of 4.2 (IQR 4-4.2), P < 0.001.

Conclusion

A brief course designed to teach bystanders about opioid overdose and naloxone was feasible and effective. We encourage hospitals and other organizations to use and promulgate this model. Furthermore, we suggest the convening of a national consortium to achieve consensus on program content and delivery.

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.

The Feasibility of Using the National PulsePoint Cardiopulmonary Resuscitation Responder Network to Facilitate Overdose Education and Naloxone Distribution: Protocol for a Randomized Controlled Trial

BACKGROUND

The use of naloxone, an opioid antagonist, is a critical component of the US response to fatal opioid-involved overdoses. The importance and utility of naloxone in preventing fatal overdoses have been widely declaimed by medical associations and government officials and are supported by strong research evidence. Still, there are gaps in the current US national strategy because many opioid-involved overdose fatalities have no evidence of naloxone administration. Improving the likelihood that naloxone will be used to prevent fatal overdoses is predicated on facilitating an environment wherein naloxone is available near each overdose and can be accessed by someone who is willing and able to use it. How to accomplish this on a national scale has been unclear. However, there exists a national network of >1 million cardiopulmonary resuscitation (CPR) layperson responders and 4800 emergency responder agencies linked through a mobile phone app called PulsePoint Respond. PulsePoint responders certify that they are trained to administer CPR and are willing to respond to possible cardiac events in public. When such an event occurs near their mobile phone's location, they receive an alert to respond. These motivated citizens are ideally positioned to carry naloxone and reverse overdoses that occur in public.

OBJECTIVE

This randomized controlled trial will examine the feasibility of recruiting first responder agencies and layperson CPR responders who already use PulsePoint to obtain overdose education and carry naloxone.

METHODS

This will be a 3-arm parallel-group randomized controlled trial. We will randomly select 180 first responder agencies from the population of agencies contracting with the PulsePoint Foundation. The 3 study arms will include a standard recruitment arm, a misperception-correction recruitment arm, and a control arm (1:1:1 allocation, with random allocation stratified by zip code designation [rural or nonrural]). We will study agency recruitment and, among the agencies we successfully recruit, responder certification of receiving overdose and naloxone education, carrying naloxone, or both. Hypothesis 1 contrasts agency recruitment success between arms 1 and 2, and hypothesis 2 contrasts the ratios of layperson certification across all 3 arms. The primary analyses will be a logistic regression comparing the recruitment rates among the arms, adjusting for rural or nonrural zip code designation.

RESULTS

This study was reviewed by the Indiana University Institutional Review Board (20218 and 20219). This project was funded beginning September 14, 2023, by the National Institute on Drug Abuse.

CONCLUSIONS

The hypotheses in this study will test whether a specific type of messaging is particularly effective in recruiting agencies and layperson responders. Although we hypothesize that arm 2 will outperform the other arms, our intention is to use the best-performing approach in the next phase of this study if any of our approaches demonstrates feasibility.

The joy and pain of being a harm reduction worker: a qualitative study of the meanings about harm reduction in Brazil

BACKGROUND

Although harm reduction is highlighted as an effective intervention for alcohol and drug use, a funding gap for harm reduction interventions has been identified, mainly in low- and middle-income countries. In these countries, tensions between abstinence and harm reduction models have impaired the shift from punitive practices to evidence-based interventions committed to guaranteeing the human rights of people who use drugs. Since 2015, the Brazilian government has adopted a more punitive and abstinence-focused drug policy that jeopardizes the care of people who use alcohol and other drugs and the comprehension of the harm reduction workers' perspective in relation to their practice. Therefore, this study aimed to comprehend the meanings constructed by Brazilian harm reduction workers regarding their practices with vulnerable populations amidst a context of political tension.

METHODS

We conducted 15 in-depth semi-structured qualitative interviews with harm reduction workers employed in public health services for at least 6 months. Data were analyzed using thematic analysis.

RESULTS

The thematic axis "The joy and pain of being a harm reduction worker in Brazil" was constructed and divided into four major themes: (1) Invisibility of harm reduction work; (2) Black, poor, and people who use drugs: identification with the service users; (3) Between advocacy and profession: harm reduction as a political act; (4) Small achievements matter. Despite the perceived invisibility of harm reduction workers in the public health and alcohol and drug fields, valuing small achievements and advocacy were important resources to deal with political tension and punitive strategies in Brazil. The findings also highlight the important role of harm reduction workers due to their personal characteristics and understanding of drug use behavior, which bring the target audience closer to actions within the public health system.

CONCLUSION

There is an urgent need to acknowledge harm reduction based on peer support as a professional category that deserves adequate financial support and workplace benefits. Additionally, expanding evidence-based harm reduction interventions and community-based voluntary drug use treatment centers should be prioritized by public policies to address the human rights violations experienced by people who use drugs.

Overdose education and naloxone distribution program design informed by people who use drugs and naloxone distributors

People who use drugs (PWUD) are the most directly affected by the overdose epidemic. However, they are not often targets of overdose education and naloxone distribution (OEND) programs. Instead, these programs target friends or family members of people prescribed opioids or general community members. This study aimed to understand the perspectives of PWUD and community naloxone distributors on OEND program design. We used a community-based participatory research model to elucidate participant perspectives on what OEND programs should look like in the context of each individual's specific risk environment. We conducted semi-structured in-depth interviews with PWUD and naloxone distributors (n = 30) in New Brunswick and Newark, New Jersey between February and November of 2022. We analyzed interviews using thematic analysis and identified the following themes: increasing naloxone knowledge, peer-based naloxone access, increasing PWUD-informed OEND program design, and desired broader OEND program scope. All Participants knew what naloxone was and emphasized that naloxone needed to be ubiquitous in the community. Participants prioritized peer-based distribution, integrating distribution into community organizations, and addressing psychosocial issues related to naloxone administration and drug use. In summary, PWUD and community naloxone distributors emphasized peer-led community naloxone distribution that prioritized novel ways for PWUD to access naloxone. OEND program design should prioritize PWUD's perspectives and direct community naloxone distribution.

Developing a single-session strategy for the implementation of take-home naloxone by community pharmacists using COM-B and design-thinking

Background

Despite the overwhelming evidence of its effectiveness, there is poor implementation of take-home naloxone by pharmacists. Barriers have been explored and mapped to the capability, opportunity, motivation-behaviour (COM-B) model of behaviour change, yet no theoretically informed implementation strategies that target known barriers have been developed. Single-session implementation strategies have been proposed as a simple, scalable way to target multiple barriers.

Methods

Qualitative participatory methods, incorporating design-thinking principles, were used to develop the key messages of a single-session implementation strategy. The key messages were drafted against COM-B mapped implementation barriers identified in the literature. A participatory workshop involving a pre-mortem exercise and incorporating design-thinking principles were used to refine the messages and generate methods for dissemination. Messages were mapped to interview questions to naturally illicit stories and delivered via storytelling from a pharmacist, a general practitioner, and a person with lived experience of using naloxone.

Results

A 3 minute 40 second video and a two-page printable infographic were developed and hosted on a website, with links to additional downloadable resources as a single-session implementation strategy. Email was the preferred method for receiving simple professional development communications, with social media also widely accessed.

Discussion

Implementation science, behavioural change theory, and participatory design methods are a complementary combination to develop implementation strategies. Some pharmacists questioned the participatory design approach to developing an implementation strategy, as it was outside of their comfort zone. However, the participatory process involving end-users resulted in unique ideas that are unlikely to have been generated using more traditional consultative approaches. The delivery as a single-session implementation strategy allows for widespread dissemination and delivery at scale.

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.

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.

Barriers and facilitators of naloxone and safe injection facility interventions to reduce opioid drug-related deaths: A qualitative analysis

BACKGROUND

Opioid drug-related deaths continue to be a significant public health concern in the Republic of Ireland (ROI) and Northern Ireland (NI). While both regions have implemented naloxone to reduce drug related deaths, there remains a gap in the implementation of a supervised injection facility (SIF). This study aimed to identify barriers and facilitators to implementing naloxone and a SIF to reduce opioid drug-related deaths in ROI and NI.

METHODS

Semi-structured interviews (n=23) were conducted in ROI and NI with experts by experience (n=8), staff from low threshold services (n=9), and individuals involved in policy making (n= 6). Data were analyzed using coding reliability Thematic Analysis and were informed by the Risk Environmental Framework.

RESULTS

The findings illustrated that stigma within the media, health centers, and the community was a significant barrier to naloxone distribution and SIF implementation. Policing and community intimidation were reported to hinder naloxone carriage in both the ROI and NI, while threats of paramilitary violence towards people who use drugs were unique to NI. Municipal government delays and policy maker apathy were reported to hinder SIF implementation in the ROI. Participants suggested peer-to-peer naloxone delivery and amending legislation to facilitate non-prescription naloxone would increase naloxone uptake. Participants recommended using webinars, Town Halls, and a Citizens' Assembly as tools to advocate for SIF implementation.

CONCLUSION

Local and regional stigma reduction campaigns are needed in conjunction with policy changes to advance naloxone and a SIF. Tailoring stigma campaigns to incorporate the lived experience of people who use drugs, their family members, and the general community can aid in educating the public and change negative perceptions. This study highlights the need for ongoing efforts to reduce stigma and increase accessibility to evidence-based interventions to address opioid drug-related deaths in the ROI, NI, and internationally.

Predisposing, enabling and reinforcing factors associated with opioid addiction helping behaviour in tri-state Appalachian counties: application of the PRECEDE-PROCEED model-cross-sectional analysis

OBJECTIVES

The overdose epidemic was designated a 'Public Health Emergency' in the USA on 26 October 2017, bringing attention to the severity of this public health problem. The Appalachian region remains substantially impacted by the effects from years of overprescription of opioids, and subsequently opioid non-medical use and addiction. This study aims to examine the utility of the PRECEDE-PROCEED model constructs (ie, predisposing, reinforcing and enabling factors) to explain opioid addiction helping behaviour (ie, helping someone who has an opioid addiction) among members of the public living in tri-state Appalachian counties.

DESIGN

Cross-sectional study.

SETTING

Rural county in the Appalachian region of the USA.

PARTICIPANTS

A total of 213 participants from a retail mall in a rural Appalachian Kentucky county completed the survey. Most participants were between the ages of 18 and 30 years (n=68; 31.9%) and identified as men (n=139; 65.3%).

PRIMARY OUTCOME MEASURE

Opioid addiction helping behaviour.

RESULTS

The regression model was significant (F _{(6, 180)}=26.191, p<0.001) and explained 44.8% of the variance in opioid addiction helping behaviour (R²=0.448). Attitude towards helping someone with opioid addiction (B=0.335; p<0.001), behavioural skills (B=0.208; p=0.003), reinforcing factors (B=0.190; p=0.015) and enabling factors (B=0.195; p=0.009) were all significantly associated with opioid addiction helping behaviour.

CONCLUSIONS

PRECEDE-PROCEED model constructs have utility to explain opioid addiction helping behaviour among individuals in a region greatly impacted by the overdose epidemic. This study provides an empirically tested framework for future programmes addressing helping behaviour related to opioid non-medical use.

(Re)situating expertise in community-based overdose response: Insights from an ethnographic study of overdose prevention sites (OPS) in Vancouver, Canada

Overdose Prevention Sites (OPS) are low-barrier services where people may use illicit drugs under the monitoring of staff trained to provide life-saving care in the event of an overdose. In British Columbia (BC), Canada, OPS have been rapidly scaled-up as a community-based response to the overdose crisis and are staffed primarily by community members who are also people who use drugs (PWUD). While it is known that PWUD perform vital roles in OPS and other community-based overdose interventions, the expertise and expert knowledge of PWUD in this work remains under-theorised. This study draws on 20 months of ethnographic fieldwork in Vancouver, BC (July 2018 to March 2020), to explore how OPS responders who are PWUD developed and enacted expertise in overdose response. Ethnographic fieldwork focused on four OPS located in Vancouver's Downtown Eastside (DTES) and Downtown South neighbourhoods. Methods included 100 hours of observation in the sites and surrounding areas, three site-specific focus groups with OPS responders (n=20), and semi-structured interviews with OPS responders (n=14) and service users (n=23). Data was analysed with the aim of characterizing the knowledge underpinning responders' expertise, and the arrangements which allow for the formation and enactment of expertise. We found that OPS responders' expertise was grounded in experiential knowledge acquired through their positionality as PWUD and members of a broader community of activists engaged in mutual aid. Responders became skilled in overdose response through frequent practice and drew on their experiential and embodied knowledge of overdose to provide care that was both technically proficient and responsive to the broader needs of PWUD (e.g. protection from criminalization and stigmatizing treatment). Responders emphasized that the spatial arrangements of OPS supported the development of expertise by facilitating more specialized and comprehensive overdose care. OPS became sites of collective expertise around overdose management as responder teams developed shared understandings of overdose management, including processes for managing uncertainty, delegating team responsibilities, and sharing decision-making. This research re-situates theoretical understandings of expertise in community-based overdose response with implications for overdose prevention interventions. Findings underscore the experiential and embodied expertise of PWUD as community-based responders; the importance of supportive environments and team-based approaches for overdose response; and the benefits of community-driven training that extends beyond technical skills of overdose identification and naloxone administration.

Lessons from the COVID-19 pandemic for substance misuse services: findings from a peer-led study

BACKGROUND

The measures implemented to contain the spread of the COVID-19 virus disrupted the provision of substance misuse treatment and support. However, little is known about the impact of this disruption on individuals seeking treatment for drug- and/or alcohol-related problems (henceforth service users). This study aimed to help substance misuse services learn lessons and identify ways of optimising delivery and minimising harm in the event of any future lockdowns or global crises.

METHODS

The study was co-produced by a team of peer researchers, practitioners, policymakers and academics. Telephone interviews were conducted with 202 substance misuse service users over a 6-month period commencing June 2020. The interviews were conducted by a small group of seven peer researchers each with lived experience of substance use problems. The interview data were recorded by the peers in an anonymous online questionnaire survey and analysed using standard quantitative and qualitative methods.

RESULTS

Service users responded to the COVID-19 pandemic in a variety of ways. Diverse responses were noted in relation to their substance use patterns, their personal lives and their substance misuse treatment experiences. For some, the pandemic acted as a new risk environment factor that increased their vulnerability to substance-related harm. For others, it facilitated aspects of the enabling environment, thereby reducing the risk of harm.

CONCLUSIONS

Service users are not a homogenous group, and an individualised approach to treatment that recognises the potential for varied responses to the same stimuli is needed. The findings suggest that service users would benefit from having a choice in how they access treatment and from greater access to outreach programmes that take treatments and harm reduction tools such as naloxone into the community. The research also supports the involvement of people with lived experience in substance use research, policy and practice.

The United Kingdom's first unsanctioned overdose prevention site; A proof-of-concept evaluation

BACKGROUND

The United Kingdom (UK) is currently experiencing a public health crisis of drug-related deaths. The government has rejected recommendations to open overdose prevention services, under the Misuse of Drugs Act 1971. To report on the operation and use of an unsanctioned overdose prevention service which operated in Glasgow city centre from September 2020 to May 2021.

METHODS

Description of the service, with analysis of data collected on its use.

RESULTS

The service operated for nine months without permission or funding from official sources. We report on the 894 injections supervised and recorded, and nine successful interventions with overdose events (seven opioid/two cocaine). Powder cocaine injection predominated either alone (60.6%) or with heroin (22.1%). Injection was mostly in the groin (68.0%) or arm (16.8%). More injections were recorded by males (70.1%). Around 65% of injection events featured an individual who was on a buprenorphine/methadone prescription.

CONCLUSION

It is feasible for an overdose prevention service to operate successfully in the UK without being shut down by the police or with negative consequences for the community. Future sites in the UK must tailor to the substances used by their potential clients, international trends (e.g. for fentanyl use) did not apply here. There is an urgent need and demand for these services in the UK to reduce harm, prevent and intervene during overdose, and provide vital psychosocial support for health and wellbeing in a highly marginalised population.
