A mapping review of take-home naloxone for people released from correctional settings

Rapid jail-based implementation of overdose education and naloxone distribution in response to the COVID-19 pandemic

BACKGROUND

People incarcerated in jails are highly impacted by the opioid epidemic, and overdose education and naloxone distribution (OEND) is an effective strategy to reduce opioid overdose deaths. This study examines barriers and facilitators of fast-track OEND implementation within the jails in the Wave 1 Kentucky counties of the HEALing Communities Study during the COVID-19 pandemic.

METHODS

Meeting minutes with jail stakeholders were qualitatively coded using the Practical, Robust Implementation and Sustainability Model (PRISM) as the coding framework. The analysis highlighted the top barriers and facilitators to fast-track OEND implementation within the PRISM framework.

RESULTS

Space and staffing shortages related to the COVID-19 pandemic, disruptions in interorganizational programming from pandemic-related service suspensions, and a lack of technological solutions (e.g., reliable Internet access) for socially distanced delivery were the top barriers to fast-track OEND implementation. In addition, there were limitations on non-jail staff access to jails during COVID-19. Top facilitators included jail leadership support, the option to prioritize high-risk groups, and the incorporation of OEND processes into existing communications and management software. While the COVID-19 pandemic strained jail infrastructure, jail and partner agency collaboration led to creative implementation strategies for the successful integration of OEND into jail operations. Urban jails were more likely than rural jails to be early adopters of OEND during the public health emergency.

CONCLUSIONS

Understanding the barriers to and facilitators of OEND within jails will improve implementation efforts seeking to curb opioid overdose deaths. Jail leadership support and interorganizational efforts were key facilitators to implementation; therefore, it is recommended to increase buy-in with multiple agencies to promote success. Challenges brought on by COVID-19 have resulted in a need for innovative solutions for implementation.

Fatal and nonfatal opioid overdose risk following release from prison: A retrospective cohort study using linked administrative data

INTRODUCTION

Among individuals who are released from prison, opioid overdose is a leading cause of death with a risk more than ten-fold the general population. Although the epidemiology of opioid-related fatalities has been described, few studies have characterized both fatal and nonfatal opioid-related poisonings. The objective of this study was to estimate risk of fatal and nonfatal opioid overdose among adults released from prison.

METHODS

The study estimated fatal and nonfatal opioid overdose rates using linked corrections, Medicaid, hospital discharge, and vital statistics from the state of Oregon from 2014 to 2018. Multivariable proportional hazards models identified demographic and prison-related factors associated with overdose.

RESULTS

Between 2014 and 2017, 18,258 individuals were released from prison. A majority of individuals were male (87 %) and ages 26 to 64 (83 %). Two-thirds had a documented substance use disorder treatment need and 20 % demonstrated mental health treatment need. Following prison release, 579 opioid overdose events occurred; 65 (11 %) were fatal. The rate of opioid overdose was 1085.7 per 100,000 person-years (PY). Rates were highest in the first two weeks (2286.7 per 100,000 PY), among women (1582.9 per 100,000 PY), and those with mental health (1624.3 per 100,000 PY) or substance use disorder treatment needs (1382.6 per 100,100 PY). Only mental health (adjusted hazard ratio [aHR] 1.54, 95 % CI 1.24 to 1.90) and substance use need (aHR 2.59; 95 % CI 2.01 to 3.34) remained significant in multivariable models.

CONCLUSIONS

The rate of opioid overdose is markedly elevated after prison release, particularly in the first two weeks. In women, the higher rate of opioid overdose is mediated by a greater mental health burden.

The acceptability of overdose alert and response technologies: introducing the TPOM-ODART framework

Background

Opioids were implicated in approximately 88,000 fatal overdoses (OD) globally. However, in principle all opioid OD are reversible with the timely administration of naloxone hydrochloride. Despite the widespread availability of naloxone among people who use opioids (PWUO), many who suffer fatal OD use alone, without others present to administer the reversal agent. Recognising this key aspect of the challenge calls for innovations, a number of technological approaches have emerged which aim to connect OD victims with naloxone. However, the acceptability of OD response technologies to PWUO is of key concern.

Methods

Drawing on the Technology People Organisations Macroenvironment (TPOM) framework, this study sought to integrate acceptability-related findings in this space with primary research data from PWUO, affected family members and service providers to understand the factors involved in harm reduction technology acceptability.

A qualitative study using a focus group methodology was conducted. The participant groups were people with lived experience of problem opioid use, affected family members and service providers. Data analysis followed a multi-stage approach to thematic analysis and utilised both inductive and deductive methods.

Results

Thirty individuals participated in one of six focus groups between November 2021 and September 2022. The analysis generated six major themes, three of which are reported in this article—selected for their close relevance to PWUO and their importance to developers of digital technologies for this group. ‘Trust—in technologies, systems and people’ was a major theme and was closely linked to data security, privacy and confidentiality. ‘Balancing harm reduction, safety and ambivalence’ reflects the delicate balance technological solutions must achieve to be acceptable to PWUO. Lastly, ‘readiness—a double bind’ encapsulates the perception shared across participant groups, that those at the highest risk, may be the least able to engage with interventions.

Conclusion

Effective digital strategies to prevent fatal OD must be sensitive to the complex relationships between technological, social/human, organisational and wider macroenvironmental factors which can enable or impede intervention delivery. Trust, readiness and performance are central to technology acceptability for PWUO. An augmented TPOM was developed (the TPOM-ODART).

Transition from nonmedical prescribed opioids to non-injection heroin use among young integrated Thai male users in Bangkok

Opioid use and misuse are understudied in Thailand despite evidence suggesting that a portion of young Thai male integrated drug users are initiating use of non-medical prescribed opioids with some transitioning to heroin. This study aims to capture and analyze the individual and social factors influencing these transitions. Twenty in-depth semi-structured interviews were conducted between December 2019 and January 2020 in the Bangkok metropolitan area with young male opioid users who transitioned to heroin. Sixteen respondents initiated opioid through a Tramadol cocktail named "YaPro" and tended to transition to heroin use within 21 months. The interaction of specific social and individual factors such as joining recreational activities, curiosity or experimentation gradually modified the opioid-related meanings, attitude and practices of Thai users, who ultimately transition to heroin use. These results indicate that drug prevention programs in Thailand should encompass young opioid users in their intervention and further research need to focus on nonmedical use of prescription opioids in Thailand.

Modeling the population-level impact of opioid agonist treatment on mortality among people accessing treatment between 2001 and 2020 in New South Wales, Australia

BACKGROUND AND AIMS

The individual-level effectiveness of opioid agonist treatment (OAT) in reducing mortality is well established, but there is less evidence on population-level benefits. We use modeling informed with linked data from the OAT program in New South Wales (NSW), Australia, to estimate the impact of OAT provision in the community and prisons on mortality and the impact of eliminating excess mortality during OAT initiation/discontinuation.

DESIGN

Dynamic modeling.

SETTING AND PARTICIPANTS

A cohort of 49 359 individuals who ever received OAT in NSW from 2001 to 2018.

MEASUREMENTS

Receipt of OAT was represented through five stages: (i) first month on OAT, (ii) short (1-9 months) and (iii) longer (9+ months) duration on OAT, (iv) first month following OAT discontinuation and (v) rest of time following OAT discontinuation. Incarceration was represented as four strata: (i) never or not incarcerated in the past year, (ii) currently incarcerated, (iii) released from prison within the past month and (iv) released from prison 1-12 months ago. The model incorporated elevated mortality post-release from prison and OAT impact on reducing mortality and incarceration.

FINDINGS

Among the cohort, mortality was 0.9 per 100 person-years, OAT coverage and retention remained high (> 50%, 1.74 years/episode). During 2001-20, we estimate that OAT provision reduced overdose and other cause mortality among the cohort by 52.8% [95% credible interval (CrI) = 49.4-56.9%] and 26.6% (95% CrI =22.1-30.5%), respectively. We estimate 1.2 deaths averted and 9.7 life-years gained per 100 person-years on OAT. Prison OAT with post-release OAT-linkage accounted for 12.4% (95% CrI = 11.5-13.5%) of all deaths averted by the OAT program, primarily through preventing deaths in the first month post-release. Preventing elevated mortality during OAT initiation and discontinuation could have averted up to 1.4% (95% CrI =  0.8-2.0%) and 3.0% (95% CrI = 2.1-5.3%) of deaths, respectively.

CONCLUSION

The community and prison opioid agonist treatment program in New South Wales, Australia appears to have substantially reduced population-level overdose and all-cause mortality in the past 20 years, partially due to high retention.

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

BACKGROUND

Naloxone-based interventions as part of health systems can reverse an opioid overdose. Previous systematic reviews have identified the effectiveness of naloxone; however, the role of context and mechanisms for its use has not been explored. This realist systematic review aims to identify a theory of how naloxone works based on the contexts and mechanisms that contribute to the success of the intervention for improved outcomes.

METHODS

Pre-registered at PROSPERO, this realist review followed RAMESES standards of reporting. Keywords included 'naloxone' and ' opioid overdose'. All study designs were included. Data extraction using 55 relevant outputs based on realist logic produced evidence of two middle-range theories: Naloxone Bystander Intervention Theory and Skills Transfer Theory.

RESULTS

Harm reduction and/or low threshold contexts provide a non-judgemental approach which support in-group norms of helping and empower the social identity of the trained and untrained bystander. This context also creates the conditions necessary for skills transfer and diffusion of the intervention into social networks. Stigma and negative attitudes held by first responders and stakeholders involved in the implementation process, such as police or GPs, can prohibit the bystander response by inducing fear in responding. This interferes with skills transfer, naloxone use and carriage of naloxone kits.

CONCLUSIONS

The findings provide theoretically informed guidance regarding the harm reduction contexts that are essential for the successful implementation of naloxone-based interventions. Peer-to-peer models of training are helpful as it reinforces social identity and successful skills transfer between bystanders. Health systems may want to assess the prevalence of, and take steps to reduce opioid-related stigma with key stakeholders in contexts using a low threshold training approach to build an environment  to support positive naloxone outcomes.

Harm reduction: a public health approach to prison drug use

PURPOSE

As prison drug use continues to be a concern worldwide, harm reduction practices serve as an alternative approach to traditional abstinence-only or punishment-oriented methods to address substance use behind bars. The purpose of this study is to present a summary of research surrounding prison-based harm reduction programs.

DESIGN/METHODOLOGY/APPROACH

This narrative review of the international literature summarizes the harms associated with prison drug use followed by an overview of the literature surrounding three prison-based harm reduction practices: opioid agonist therapy, syringe exchange programs and naloxone distribution.

FINDINGS

A collection of international research has found that these three harm reduction programs are safe and feasible to implement in carceral settings. Additionally, these services can effectively reduce some of the harms associated with prison drug use (e.g. risky injection practices, needle sharing, fatal overdoses, etc.). However, these practices are underused in correctional settings in comparison to their use in the community.

ORIGINALITY/VALUE

Various policy recommendations are made based on the available literature, including addressing ethical concerns surrounding prison populations' rights to the same standard of health care and services available in the community. By taking a public health approach to prison drug use, harm reduction practices can provide a marginalized, high-risk population of incarcerated individuals with life-saving services rather than punitive, punishment-oriented measures.

Bridging institutional logics: Implementing naloxone distribution for people exiting jail in three California counties

Drug overdose is the leading cause of death among formerly incarcerated people. Distribution of the opioid overdose medication naloxone to people who use drugs reduces overdose mortality, and officials in many jurisdictions are now considering or implementing programs to offer naloxone to people exiting jails and prisons. The principles and practices of harm reduction programs such as naloxone distribution conflict with those of penal institutions, raising the question of how organizations based on opposing institutional logics can collaborate on lifesaving programs. Using in-depth interviews and observations conducted over four years with 34 penal, medical, public health, and harm reduction practitioners, we introduce and conceptualize two organizational features to explain why this therapeutic intervention was implemented in local jails in two of three California counties. First, interorganizational bridges between harm reduction, medical, and penal organizations facilitated mutual understanding and ongoing collaboration among administrators and frontline workers in different agencies. Second, respected and influential champions within public health and penal organizations put jail-based naloxone distribution on the local agenda and cultivated support among key officials. Our findings offer guidance for future studies of institutional logics and policy responses to the overdose crisis.

Fentanyl-related overdose during incarceration: a comprehensive review

BACKGROUND

Fentanyl and related compounds have recently saturated the illicit drug supply in the United States, leading to unprecedented rates of fatal overdose. Individuals who are incarcerated are particularly vulnerable, as the burden of opioid use disorder is disproportionately higher in this population, and tolerance generally decreases during incarceration.

METHODS

We conduct a systematic search for publications about fentanyl overdoses during incarceration in PubMed and PsycINFO, as well as lay press articles in Google, from January 1, 2013 through March 30th, 2021.

RESULTS

Not a single fentanyl overdose was identified in the medical literature, but 90 overdose events, comprising of 76 fatal and 103 nonfatal fentanyl overdoses, were identified in the lay press. Among the 179 overdoses, 138 occurred in jails and 41 occurred in prisons, across the country.

CONCLUSIONS

Fentanyl-related overdoses are occurring in correctional facilities with unknown but likely increasing frequency. In addition to the need for improved detection and reporting, immediate efforts to 1) increase understanding of the risks of fentanyl and how to prevent and treat overdose among correctional staff and residents, 2) ensure widespread prompt availability of naloxone and 3) expand the availability of medications to treat opioid use disorder for people who are incarcerated will save lives.

Take-home naloxone programs for suspected opioid overdose in community settings: a scoping umbrella review

BACKGROUND

Opioid related overdoses and overdose deaths continue to constitute an urgent public health crisis. The implementation of naloxone programs, such as 'take-home naloxone' (THN), has emerged as a key intervention in reducing opioid overdose deaths. These programs aim to train individuals at risk of witnessing or experiencing an opioid overdose to recognize an opioid overdose and respond with naloxone. Naloxone effectively reverses opioid overdoses on a physiological level; however, there are outstanding questions on community THN program effectiveness (adverse events, dosing requirements, dose-response between routes of administration) and implementation (accessibility, availability, and affordability). The objective of this scoping review is to identify existing systematic reviews and best practice guidelines relevant to clinical and operational guidance on the distribution of THN.

METHODS

Using the Arksey & O'Malley framework for scoping reviews, we searched both academic literature and grey literature databases using keywords (Naloxone) AND (Overdose) AND (Guideline OR Review OR Recommendation OR Toolkit). Only documents which had a structured review of evidence and/or provided summaries or recommendations based on evidence were included (systematic reviews, meta-analyses, scoping reviews, short-cut or rapid reviews, practice/clinical guidelines, and reports). Data were extracted from selected evidence in two key areas: (1) study identifiers; and (2) methodological characteristics.

RESULTS

A total of 47 articles met inclusion criteria: 20 systematic reviews; 10 grey literature articles; 8 short-cut or rapid reviews; 4 scoping reviews; and 5 other review types (e.g. mapping review and comprehensive reviews). The most common subject themes were: naloxone effectiveness, safety, provision feasibility/acceptability of naloxone distribution, dosing and routes of administration, overdose response after naloxone administration, cost-effectiveness, naloxone training and education, and recommendations for policy, practice and gaps in knowledge.

CONCLUSIONS

Several recent systematic reviews address the effectiveness of take-home naloxone programs, naloxone dosing/route of administration, and naloxone provision models. Gaps remain in the evidence around evaluating cost-effectiveness, training parameters and strategies, and adverse events following naloxone administration. As THN programs continue to expand in response to opioid overdose deaths, this review will contribute to understanding the evidence base for policy and THN program development and expansion.

A scoping review of factors that influence opioid overdose prevention for justice-involved populations

BACKGROUND

There is a high risk of death from opioid overdose following release from prison. Efforts to develop and implement overdose prevention programs for justice-involved populations have increased in recent years. An understanding of the gaps in knowledge on prevention interventions is needed to accelerate development, implementation, and dissemination of effective strategies.

METHODS

A systematic search process identified 43 published papers addressing opioid overdose prevention in criminal justice settings or among justice-involved populations from 2010 to February 2020. Cross-cutting themes were identified, coded and qualitatively analyzed.

RESULTS

Papers were coded into five categories: acceptability (n = 8), accessibility (n = 4), effectiveness (n = 5), feasibility (n = 7), and participant overdose risk (n = 19). Common themes were: (1) Acceptability of naloxone is associated with injection drug use, overdose history, and perceived risk within the situational context; (2) Accessibility of naloxone is a function of the interface between corrections and community; (3) Evaluations of overdose prevention interventions are few, but generally show increases in knowledge or reductions in opioid overdose; (4) Coordinated efforts are needed to implement prevention interventions, address logistical challenges, and develop linkages between corrections and community providers; (5) Overdose is highest immediately following release from prison or jail, often preceded by service-system interactions, and associated with drug-use severity, injection use, and mental health disorders, as well as risks in the post-release environment.

CONCLUSION

Study findings can inform the development of overdose prevention interventions that target justice-involved individuals and policies to support their implementation across criminal justice and community-based service systems.

Feasibility and acceptability of take-home naloxone for people released from prison in New South Wales, Australia

INTRODUCTION AND AIMS

To assess the feasibility and acceptability of a take-home naloxone program for people with a history of opioid use released from prison in New South Wales, Australia.

DESIGN AND METHODS

Cross-sectional interviews with people with a history of opioid use who were recently released from prison (n = 105), and semi-structured interviews with key clinical and operational staff of Justice Health and Forensic Mental Health Network and Corrective Services NSW (n = 9).

RESULTS

Among people with a history of opioid use who had recently left prison, there was very high awareness of the elevated risk of overdose following release from prison (95%) and the potential for naloxone to reverse an opioid overdose (97%). Participants considered that their personal risk of overdose was low, despite ongoing opioid use being common. Participants were largely supportive of take-home naloxone, but the majority (83%) stated that proactively obtaining naloxone would be a low priority for them following release. Key informants were supportive of introducing naloxone training and supply and identified barriers to implementation, including adequate resourcing, identifying the population for training, and developing an appropriate model of training and implementation.

DISCUSSION AND CONCLUSION

There was widespread support for naloxone training in custody and distribution at release among people recently released from prison and key stakeholders in health-care provision and prisons administration. As proactively accessing naloxone is a low priority for patients, naloxone supply at release may be more effective than programs that refer releasees to local pharmacies, but developing a sustainable supply model requires consideration of several barriers.

Justice involvement patterns, overdose experiences, and naloxone knowledge among men and women in criminal justice diversion addiction treatment

Background

Persons in addiction treatment are likely to experience and/or witness drug overdoses following treatment and thus could benefit from overdose education and naloxone distribution (OEND) programs. Diverting individuals from the criminal justice system to addiction treatment represents one treatment engagement pathway, yet OEND needs among these individuals have not been fully described.

Methods

We characterized justice involvement patterns among 514 people who use opioids (PWUO) participating in a criminal justice diversion addiction treatment program during 2014–2016 using a gender-stratified latent class analysis. We described prevalence and correlates of naloxone knowledge using quasi-Poisson regression models with robust standard errors.

Results

Only 56% of participants correctly identified naloxone as an opioid overdose treatment despite that 68% had experienced an overdose and 79% had witnessed another person overdose. We identified two latent justice involvement classes: low involvement (20.3% of men, 46.5% of women), characterized by older age at first arrest, more past-year arrests, and less time incarcerated; and high involvement (79.7% of men, 53.5% of women), characterized by younger age at first arrest and more lifetime arrests and time incarcerated. Justice involvement was not associated with naloxone knowledge. Male participants who had personally overdosed more commonly identified naloxone as an overdose treatment after adjustment for age, race, education level, housing status, heroin use, and injection drug use (prevalence ratio [95% confidence interval]: men 1.5 [1.1–2.0]).

Conclusions

All PWUO in criminal justice diversion programs could benefit from OEND given the high propensity to experience and witness overdoses and low naloxone knowledge across justice involvement backgrounds and genders.

An evaluation of Take Home Naloxone program implementation in British Columbian correctional facilities

Purpose

To understand how the Take Home Naloxone (THN) program is implemented in two pilot correctional facilities in British Columbia (BC), Canada, in order to identify areas for program improvement and inform the expansion of the program to other Canadian correctional facilities The paper aims to discuss these issues.

Design/methodology/approach

Two focus groups and one interview were conducted with healthcare staff at two pilot correctional facilities. Sessions were audio recorded, transcribed verbatim and divergent and convergent experiences within and between the facilities were explored in an iterative process. Key themes and lessons learned were identified and later validated by focus group participants.

Findings

Key themes that emerged included: challenges and importance of the train-the-trainer program for healthcare staff conducting participant training sessions; potential for improved prison population engagement and awareness of the program; tailoring program resources to the unique needs of an incarcerated population; challenges connecting participants to community harm reduction resources following release; and clarifying and enhancing the role of correctional officers to support the program.

Research limitations/implications

The correctional setting presents unique challenges and opportunities for the THN program that must be considered for program effectiveness.

Originality/value

This evaluation was conducted to inform program expansion amidst a historic opioid overdose epidemic in BC, and adds to the limited yet growing body of literature on the implementation and evaluation of this program in correctional settings globally.

Acceptability of prison-based take-home naloxone programmes among a cohort of incarcerated men with a history of regular injecting drug use

Background

Take-home naloxone (THN) programmes are an evidence-based opioid overdose prevention initiative. Elevated opioid overdose risk following prison release means release from custody provides an ideal opportunity for THN initiatives. However, whether Australian prisoners would utilise such programmes is unknown. We examined the acceptability of THN in a cohort of male prisoners with histories of regular injecting drug use (IDU) in Victoria, Australia.

Methods

The sample comprised 380 men from the Prison and Transition Health (PATH) Cohort Study; all of whom reported regular IDU in the 6 months prior to incarceration. We asked four questions regarding THN during the pre-release baseline interview, including whether participants would be willing to participate in prison-based THN. We describe responses to these questions along with relationships between before- and during-incarceration factors and willingness to participate in THN training prior to release from prison.

Results

Most participants (81%) reported willingness to undertake THN training prior to release. Most were willing to resuscitate a friend using THN if they were trained (94%) and to be revived by a trained peer (91%) using THN. More than 10 years since first injection (adjusted odds ratio [AOR] 2.22, 95%CI 1.03–4.77), having witnessed an opioid overdose in the last 5 years (AOR 2.53, 95%CI 1.32–4.82), having ever received alcohol or other drug treatment in prison (AOR 2.41, 95%CI 1.14–5.07) and injecting drugs during the current prison sentence (AOR 4.45, 95%CI 1.73–11.43) were significantly associated with increased odds of willingness to participate in a prison THN programme. Not specifying whether they had injected during their prison sentence (AOR 0.37, 95%CI 0.18–0.77) was associated with decreased odds of willingness to participate in a prison THN training.

Conclusion

Our findings suggest that male prisoners in Victoria with a history of regular IDU are overwhelmingly willing to participate in THN training prior to release. Factors associated with willingness to participate in prison THN programmes offer insights to help support the implementation and uptake of THN programmes to reduce opioid-overdose deaths in the post-release period.

National Institute on Drug Abuse International Program: improving opioid use disorder treatment through international research training

PURPOSE OF REVIEW

For more than 25 years, the National Institute on Drug Abuse (NIDA) has supported research-training programs, establishing a global research network and expanding the knowledge base on substance use disorders. International research to inform approaches to opioid addiction is particularly important and relevant to the United States, where opioid misuse, addiction, and overdose constitute an emerging public health crisis. This article summarizes the NIDA International Program and illustrates its impact by reviewing recent articles about treatment approaches for opioid use disorders (OUD).

RECENT FINDINGS

Studies in several countries have demonstrated the effectiveness of physician office-based opioid substitution therapies. Other research has demonstrated the effectiveness of different formulations and doses of the opioid antagonist naltrexone, as well as different approaches to providing naloxone to treat opioid overdose. Continuing research into implementation of evidence-based treatment in international settings with limited resources is applicable to US regions that face similar structural, legal, and fiscal constraints.

SUMMARY

The current review describes international research on OUD treatment and opioid overdose, most coauthored by former NIDA fellows. The findings from outside the United States have important implications for best practices domestically and in other countries that are experiencing increases in OUD prevalence and related overdose deaths.

Overdose prevention training with naloxone distribution in a prison in Oslo, Norway: a preliminary study

BACKGROUND

Prison inmates face a ten times increased risk of experiencing a fatal drug overdose during their first 2 weeks upon release than their non-incarcerated counterparts. Naloxone, the antidote to an opioid overdose, has been shown to be feasible and effective when administered by bystanders. Given the particular risk that newly released inmates face, it is vital to assess their knowledge about opioid overdoses, as well as the impact of brief overdose prevention training conducted inside prisons.

METHODS

Prison inmates nearing release (within 6 months) in Oslo, Norway, voluntarily underwent a brief naloxone training. Using a questionnaire, inmates were assessed immediately prior to and following a naloxone training. Descriptive statistics were performed for main outcome variables, and the Wilcoxon signed-rank test was used to compare the participants' two questionnaire scores from pre-and post-training.

RESULTS

Participating inmates (n = 31) were found to have a high baseline knowledge of risk factors, symptoms, and care regarding opioid overdoses. Nonetheless, a brief naloxone training session prior to release significantly improved knowledge scores in all areas assessed (p < 0.001). The training appears to be most beneficial in improving knowledge regarding the naloxone, including its use, effect, administration, and aftercare procedures.

CONCLUSIONS

Given the high risk of overdosing that prison inmates face upon release, the need for prevention programs is critical. Naloxone training in the prison setting may be an effective means of improving opioid overdose response knowledge for this particularly vulnerable group. Naloxone training provided in the prison setting may improve the ability of inmates to recognize and manage opioid overdoses after their release; however, further studies on a larger scale are needed.
