Take-home Naloxone Programs Research Articles

Scaling up! Staff e-learning for a national take-home naloxone program.

A staff e-learning course was developed to prepare for scaling up a national take-home naloxone (THN) program in Norway. The aims of the study were to (a) describe participant characteristics for those that completed a THN e-learning course, (b) compare opioid overdose knowledge scores before and after e-learning course completion, and (c) to explore subsequent THN distribution by those trained. This was a quasi-experimental pre-test, post-test longitudinal cohort study of individuals completing a THN e-learning course from April 2021 to May 2022. Frequency analyses were performed for participant characteristics and subsequent naloxone distributions at 1-week and 1-month follow-up. The opioid overdose knowledge scale (OOKS) was used to measure pre-test-post-test knowledge among participants. Wilcoxon signed-rank test was performed for comparison between pre-test and post-test. Effect size was calculated using Cohen criteria. In total, 371 individuals were included in this study. Most were either nurses or social workers (n = 277, 75%). Participant knowledge increased by medium or large effect for all items measured. At 1-month follow-up, 15% reported naloxone distribution. During the study period, 94 naloxone kits were distributed. Major reasons for not distributing were "clients not interested", "workplace not distributing" and "workplace in process of distributing". Our findings suggest that an e-learning course is equally effective in terms of knowledge transfer as an in-person classroom setting, and may provide engagement in terms of naloxone distribution. However, our findings also emphasize the importance of clear implementation routines, including support from central coordinators to optimize the implementation process.

Naloxone cascade of care among people who regularly inject drugs in Australia, 2020–2022

BackgroundExamining take-home naloxone (THN) uptake using a ‘cascade of care’ framework could help identify targets for increasing THN training and carriage among people who may witness or experience opioid overdose. We describe the THN cascade and factors associated with engagement among people who inject drugs. MethodsPeople aged ≥18 years in Australia who inject drugs were interviewed from 2020 to 2022, reporting lifetime THN awareness and acquisition and past-month carriage. We examined factors associated with engagement using multivariable logistic regression. ResultsOf 2,149 participants (64 % men, mean age 44.5), 85 % had heard of naloxone, of whom 76 % were aware of THN programs. Of these, 72 % had ever participated in THN training/brief education, 92 % of whom had acquired THN. Of those who had ever acquired THN and reported past-month opioid use, 63 % always/often carried THN when using opioids. Past six-month opioid agonist treatment (OAT) (adjusted odds ratio [AOR] 2.55; 95 %CI 1.91–3.42) and ≥daily injecting (1.32; 1.01–1.73) were associated with awareness. OAT (1.79; 1.38–2.33), past-year opioid overdose (1.68; 1.18–2.42) and older age (1.02; 1.00–1.03) were associated with acquisition. Primarily injecting methamphetamine (versus heroin) in the past month was associated with lower awareness (0.43; 0.31–0.58) and acquisition (0.59; 0.44–0.78). Reporting no accommodation (squatting/sleeping rough) was associated with reduced odds of carriage (0.46; 0.24–0.88). ConclusionParticipants reported high THN awareness and acquisition, with lower carriage. Future efforts should focus on improving THN access and reducing barriers to carriage, particularly for people experiencing homelessness or who primarily inject non-opioids.

Descriptive before-and-after study of the introduction of a ‘Leave Behind’ take-home naloxone dispensing/distribution program by the ambulance service in Western Australia

Objective To describe changes observed in case characteristics and patient outcomes before and after ambulance service participation in a ‘Leave Behind’ take-home naloxone (THN) dispensing/distribution program. Methods This before-and-after study included emergency ambulance attendances for patients experiencing an opioid overdose one year before 1 October 2021 (pre-participation phase: 1 October 2020–30 September 2021) when St John Western Australia (SJWA) participated in the THN program and those one year after the date (post-participation phase: 1 October 2021–30 September 2022). Results There were 945 and 1240 opioid overdoses among 221,451 and 222,480 emergency ambulance attendances in the pre- and post-participation phases (0.43% vs 0.56%, p < 0.001). The number of ambulance attendances for overdose in the post-participation phase was not significantly different from that predicted based on the ambulance attendances in the pre-participation phase. No statistically significant differences in patient age, sex, and geographical location were identified between the two phases. Compared to the pre-participation phase, more patients had naloxone administered prior to ambulance arrival (10.7% vs 15.1%, p = 0.003), and more patients were discharged at the scene (21.2% vs 29.8%, p < 0.001) in the post-participation phase. No difference was found in mortality within one day (3.4% in the pre-participation phase vs 3.5% in the post-participation phase, p = 0.30). Conclusions After implementation of a ‘Leave Behind’ take-home naloxone dispensing/distribution program, more patients had naloxone administered prior to ambulance arrival, and the likelihood of discharging a patient at the scene significantly increased without affecting patient survival rates.

Mortality risk and causes of death among people who use opioids in a take-home naloxone cohort

BackgroundPeople who use opioids (PWUO) have an excess mortality from a range of causes. The cumulative effect of behavioral, social, and health risk factors complicates the interpretation of the effects of suitable interventions. This study explores mortality causes among a cohort of PWUO in the take-home naloxone (THN) program. MethodsThis was a prospective cohort study of PWUO who received THN between 2015 and 2023. Participant data was linked with death registry data. Crude mortality rates and standardized mortality ratios (SMRs) were calculated for all causes, internal causes, and accidental opioid overdoses (AOOs). In addition to age and gender, risk factors like main route of administration, polydrug use, self-experienced overdoses, and using while alone were fitted in a Cox Regression model to explore factors associated with mortality. ResultsThe 2194 participants had a considerably higher mortality ratio for all causes investigated when compared to the general population (SMR=10.9, 95 % CI = 9.3,12.6). AOOs were the most prevalent cause of death (49 %). Those who reported frequent opioid use while alone had an elevated risk of dying of 2.6 (95 % CI = 1.1,6.4) compared to those who never used while alone. ConclusionsFrequent opioid use while alone was associated with elevated mortality risk, supporting the importance of overdose prevention education with naloxone distribution, and additional efforts to improve environmental and social areas for safer drug-use practices among PWUO. The variety of mortality causes found in this study illustrates the need for multifaceted and targeted interventions for people at risk of overdosing.

Take-Home Naloxone Access and Use among Older Adults Living with Pain: A Scoping Review.

Opioids are a common treatment for older adults living with pain. Given high rates of polypharmacy and chronic comorbidities, older adults are at risk of opioid overdose. Evidence is now available that take-home naloxone (THN) supports reduction of opioid-related harms. It is unknown what THN initiatives are available for older adults, especially those living with chronic pain. To summarize the literature regarding THN, with a focus on older adults using opioids for pain, including facilitators of and barriers to THN access, knowledge gaps, and pharmacist-led initiatives. A scoping review, guided by an established framework and PRISMA-ScR guidelines, was performed. Methods involved searching 6 bibliographic databases (MEDLINE, Embase, Scopus, APA PsycINFO, Web of Science Core Collection, and PubMed), reference harvesting, and citation tracking. Searches were conducted up to March 2023, with no date limits applied; only English publications were included. Study eligibility was determined according to preset criteria, including age; discrepancies were resolved by discussion and consensus. Data were extracted and categorized through thematic analysis. Four studies met the eligibility criteria. All 4 studies detailed THN programs in primary care settings involving older adults taking opioids for pain management. Two of the studies highlighted patient-specific risk factors for opioid overdose, including concomitant use of benzodiazepines and/or gabapentinoids, mean morphine milligram equivalents per day of at least 50, and previous opioid overdose. Two of the studies assessed patient knowledge of opioid overdose management and attitudes toward THN. Educational programs increased patients' interest in THN. The literature about THN for older adults living with pain is limited, and no literature was found on pharmacist-led initiatives in this area. Future research on THN provision for older adults, including pharmacist-led initiatives, could help to optimize care for older adults living with pain.

Guidance on take-home naloxone distribution and use by community overdose responders in Canada.

The increasing toxicity of opioids in the unregulated drug market has led to escalating numbers of overdoses in Canada and worldwide; takehome naloxone (THN) is an evidence-based intervention that distributes kits containing naloxone to people in the community who may witness an overdose. The purpose of this guidance is to provide policy recommendations for territorial, provincial and federal THN programs, using evidence from scientific and grey literature and community evidence that reflects 11 years of THN distribution in Canada. The Naloxone Guidance Development Group - a multidisciplinary team including people with lived and living experience and expertise of drug use - used the Appraisal of Guidelines for Research & Evaluation (AGREE II) instrument to inform development of this guidance. We considered published evidence identified through systematic reviews of all literature types, along with community evidence and expertise, to generate recommendations between December 2021 and September 2022. We solicited feedback on preliminary recommendations through an External Review Committee and a public input process. The project was funded by the Canadian Institutes of Health Research through the Canadian Research Initiative in Substance Misuse. We used the Guideline International Network principles for managing competing interests. Existing evidence from the literature on THN was of low quality. We incorporated evidence from scientific and grey literature, and community expertise to develop our recommendations. These were in 3 areas: routes of naloxone administration, THN kit contents and overdose response. Take-home naloxone programs should offer the choice of both intramuscular and intranasal formulations of naloxone in THN kits. Recommended kit contents include naloxone, a naloxone delivery device, personal protective equipment, instructions and a carrying case. Trained community overdose responders should prioritize rescue breathing in the case of respiratory depression, and conventional cardiopulmonary resuscitation in the case of cardiac arrest, among other interventions. This guidance development project provides direction for THN programs in Canada in the context of limited published evidence, with recommendations developed in collaboration with diverse stakeholders.

A study protocol for a European, mixed methods, prospective, cohort study of the effectiveness of naloxone administration by community members, in reversing opioid overdose: NalPORS

BackgroundWorldwide, opioid use causes more than 100,000 overdose deaths annually. Naloxone has proven efficacy in reversing opioid overdoses and is approved as an emergency antidote to opioid overdose. Take home naloxone (THN) programmes have been introduced to provide ‘community members’, who are likely to observe opioid overdoses, with naloxone kits and train them to recognise an overdose and administer naloxone. The acceptability and feasibility of THN programmes has been demonstrated, but the real-life effectiveness of naloxone administration by community members is not known. In recent years, the approval of several concentrated naloxone nasal-spray formulations (in addition to injectable formulations, eg.prenoxad) potentially increases acceptability and scope for wider provision. This study aims to determine the effectiveness of THN (all formulations) in real-world conditions.MethodsA European, multi-country, prospective cohort study, to assess the use of THN by community members to reverse opioid overdoses in a six-month, follow-up period. Participants provided with THN from participating harm reduction and drug treatment sites will be recruited to the study and followed-up for six months. We are particularly interested in the experiences of community members who have been provided with THN and have witnessed an opioid overdose. All participants who witness an opioid overdose during the six-month period (target approx. 600) will be asked to take part in a structured interview about this event. Of these, 60 will be invited to participate in a qualitative interview. A Post Authorisation Efficacy Study (PAES) for the concentrated nasal naloxone, Nyxoid, has been integrated into the study design.DiscussionThere are many challenges involved in evaluating the real-life effectiveness of THN. It is not possible to use a randomised trial design, recruitment of community members provided with THN will depend upon recruitment sites distributing THN kits, and the type of THN received by participants will depend on regulations and on local clinical and policy decision-makers. Following up this population, some of whom may be itinerant, over the 6-month study period will be challenging, but we plan to maintain contact with participants through regular text message reminders and staff contact.Trial registrationClinicalTrials.gov Identifier: NCT05072249.

"It can save your life, that's all I know," barriers and facilitators for engagement in take-home naloxone for people receiving opioid substitution treatment in regional Australia: An explorative study.

Engagement in take-home naloxone (THN) programs by people receiving opioid substitution treatment (OST) in Australia is low despite methadone being a significant contributor to opioid overdose deaths. Our aim was to explore barriers and facilitators for OST patients to engage in THN. We used a descriptive qualitative design with thematic analysis to gain insight into naloxone uptake by people engaged in an OST program in regional Australia. Eleven participants were interviewed; eight had previously engaged with THN. Barriers to THN included limited knowledge and understanding, lack of information, and not personally experiencing an overdose. Facilitators included having a traumatic experience of overdose, knowledge and understanding of THN and overdose, empowerment in carrying naloxone, and expanding THN programs. Support for the expansion of THN programs is desired among participants, and widespread peer distribution is understood to be the key to success. This study found that prior traumatic experience of overdose facilitates acceptance of THN, and being offered THN was the most important factor in engagement. Less clear is how to engage people who lack a traumatic overdose experience.

Take-Home Naloxone and risk management from the perspective of people who survived an opioid overdose in Stockholm - An analysis informed by drug, set and setting.

Take-Home Naloxone (THN) programs were introduced in Sweden in 2018 - a country with one of the highest rates of overdose mortality in the EU and a severe stigmatisation of people who inject drugs. This qualitative study builds on the international research that has expanded a previously narrow and medical focus on overdose deaths. It uses Zinberg's framework to look beyond the role of the "drug" to include the attitudes and personality of the person ("set") and contextual factors ("setting"). This study explores the impacts of THN from the perspective of overdose survivors. Between November 2021 and May 2022 semi-structured interviews were conducted with 22 opioid overdose survivors, recruited among clients of the Stockholm needle and syringe program. All the participants had been treated with naloxone in an overdose situation. The interviews were processed through thematic analysis using deductive and inductive coding in accordance with the theoretical framework. Interviewees included men and women who used different types of drugs. THN has impacted on "drug" in terms of naloxone-induced withdrawal symptoms and peers having to deal with survivors' emotions. Exploring "set" revealed feelings of shame following naloxone revival for the person who overdosed. Despite such reactions, participants retained an overwhelmingly positive attitude towards THN. Participants integrated THN into their risk management practices ("setting") and some acknowledged that THN provided a new way to treat overdoses without necessarily needing to interact with authorities, especially the police. The THN program has influenced "drug, set and setting" for participants, providing increased safety at drug-intake and transferring overdose management and the burden of care to the community. The lived experience of participants also exposes the limitations of THN indicating that there are additional unmet needs beyond THN programs, particularly in terms of "setting".

Sweden’s first Take-Home Naloxone program: participant characteristics, dose endpoints and predictors for overdose reversals

BackgroundOpioid overdoses are a growing concern, particularly among people who inject drugs. Sweden, with a comparatively high proportion of drug-related mortality, introduced its first Take-Home Naloxone (THN) program in 2018, at the Stockholm needle and syringe program (NSP). In this study we compare THN participant characteristics regarding refills and overdose reversals as well as investigate predictors associated with number of reversals. We also investigate interventions performed in overdose situations and endpoints for naloxone doses.MethodsThis was a prospective open inclusion cohort study conducted between January 24th 2018 and March 31st 2022 at the Stockholm NSP. Participants received THN, free of charge, after a training session and provided data regarding drug use and overdose experiences. During refill visits, participants reported if the naloxone was used for overdose reversal and, if so, responded to a ten-item questionnaire which included stating whether the naloxone recipient was the participant themselves or somebody else. Questionnaire data was combined with NSP database demographic data. Zero-inflated Poisson regression was applied to analyse predictors for number of reported overdose reversals.ResultsAmong study participants (n = 1,295), 66.5% stated opioids as their primary drug, and 61.4% and 81.0% had previous experience of a personal or witnessed overdose, respectively. Overall, 44.0% of participants reported a total of 1,625 overdose reversals and the victim was known to have survived in 95.6% of cases. Stimulant use (aIRR 1.26; 95% CI 1.01, 1.58), benzodiazepine use (aIRR 1.75; 95% CI 1.1, 2.78) and homelessness (aIRR 1.35; 95% CI 1.06, 1.73) were predictors associated with an increased number of reported overdose reversals. Mortality was higher among those who reported at least one overdose reversal (HR 3.4; 95% CI 2.2, 5.2).ConclusionsAn NSP’s existent framework can be utilised to effectively implement a THN program, provide basic training and reach numerous high-risk individuals. During the four-year study, THN participants reversed a sizeable number of potentially fatal overdoses, of which many were reported by participants whose primary drug was not opioids. Naloxone refill rate was high, indicating that participants were motivated to maintain a supply of naloxone in case of future overdose events.

High-risk Individuals and Naloxone Use: Implications for THN Programs in Rural Appalachian Communities.

Take-home naloxone (THN) is being made available across rural Appalachia to curb opioid overdose fatalities. Despite this initiative, some opioid users do not possess naloxone, and if they do, do not administer it to others. Research findings on risk factors that contribute to opioid overdose are presented. These factors, identified in a sample of 16 overdose cases, are (1) early onset age of opioid use; (2) progressive opioid use; (3) a transition from pain medication to heroin and fentanyl; (4) fears of being arrested at a naloxone intervention if first responders are contacted, and (5) limited knowledge of Good Samaritan Laws. The findings are based on a subsample 16 overdose victims who were identified during a one-year (2018) qualitative study on the decline of overdose fatalities in four rural counties in Western Pennsylvania. They were recruited from a larger sample of 50 current and former substance users and were interviewed a second time using a semi-structured interview guide about their overdose experiences. All interview data were analyzed using thematic analysis via NVivo. Findings reveal that risk factors contribute to a severe opioid dependence that interferes with naloxone use. These factors also hinder adherence to proper naloxone protocol, designed to place overdose victims in contact with treatment providers. Recommendations are made for additional research and for pursuing measures to increase efficacy of naloxone interventions. They include developing naloxone campaigns aimed at high-risk individuals, improving their knowledge of Good Samaritan Laws, increasing adherence to THN protocols that improve the possibility of treatment, and using community harm reduction specialists for community outreach.

Overview of availability of harm reduction interventions in European prisons

Abstract Introduction Prisons are high-risk environments for the transmission of drug related infections, due to over-incarceration of people who inject drugs; often inadequate healthcare, substandard prison conditions; and others. An overview of the availability and coverage of prison-based harm reduction interventions in Europe is presented. Methods National Focal Points of the EMCDDA (30) collected 2019 data, which were integrated with findings from the European funded project HA-REACT (Joint Action on HIV and Co-infection Prevention and Harm Reduction). Results Prison based harm reduction interventions are available in European countries, but only few of them are available in most countries and often with a low coverage (e.g. less than 10% of prison population in Opioid Substitution Treatment (OST) in most countries). Interventions available in most countries (20 or more) include: HIV, HBV, HCV testing (29), OST continued from community (29), Referral to HIV treatment upon release (28), HIV treatment (27), Referral to HCV treatment upon release (25), HCV antiviral treatment (25), Testing for TB (23), HBV antiviral therapy (25), OST initiated in prison (22), Treatment for TB (21), Vaccination for HBV (20). Interventions available in 10 to 19 countries are: condom distribution (19), OST (re)initiated before release (17), prison/community guidelines for implementation of OST (13). Interventions provided in < 10 countries include: distribution of disinfectant (9), condom with lubricant (9), take-home naloxone (5), needles and syringes programs (3). Conclusions Compared to the community, the availability and coverage of harm reduction interventions in European prisons are limited and large information gaps exist. Scaling up harm reduction in prison can achieve important individual and public-health benefits.

A systematic review of the distribution of take-home naloxone in low- and middle-income countries and barriers to the implementation of take-home naloxone programs

BackgroundOpioid overdose epidemic is hitting record highs worldwide, accounting for 76% of mortality related to substance use. Take-home naloxone (THN) strategies are being implemented in many developed countries that suffer from high opioid overdose death rates. They aim to provide overdose identification and naloxone administration training, along with THN delivery to opioid users and others likely to witness an overdose incident such as family members and peers. However, little is known about such measures in low- and middle-income countries (LMIC), where opioid use and opioid-related deaths are reportedly high. This systematic literature review aims to examine the distribution of THN in LMIC, review studies identifying barriers to the implementation of THN programs worldwide, and assess their applicability to LMIC.MethodsThe literature was searched and analyzed for eligible studies with quality assessment.ResultsTwo studies were found from LMIC on THN programs with promising results, and 13 studies were found on the barriers identified in implementing THN programs worldwide. The main barriers to THN strategies were the lack of training of healthcare providers, lack of privileges, time constraints, cost, legislative/policy restrictions, stigma, fear of litigation, and some misperceptions around THN.ConclusionsThe barriers outlined in this paper are probably applicable to LMIC, but more difficult to overcome considering the differences in their response to opioid overdose, their cultural attitudes and norms, the high cost, the waivers required, the legislative differences and the severe penalties for drug-related offenses in some of these countries. The solutions suggested to counter-act these obstacles can also be more difficult to achieve in LMIC. Further research is required in this area with larger sample sizes to provide a better understanding of the obstacles to the implementation, feasibility, accessibility, and utilization of THN programs in LMIC.

Risks and overdose responses: Participant characteristics from the first seven years of a national take-home naloxone program

BackgroundIn 2014, the Norwegian government funded a large-scale take-home naloxone (THN) program to address high overdose mortality rates. The aims of this study are to describe characteristics among persons trained to receive THN, describe actions taken following THN use at an overdose event and to explore factors associated with naloxone use. MethodsThis was a prospective cohort study of individuals who received THN from 2014 to 2021. Descriptive characteristics were collected at initial training. When returning for refill, participants reported on their previous naloxone use. In a multivariable logistic regression model exploring associations with naloxone use: gender, age, opioid use history, concomitant drug use, injecting, history of experienced or witnessed overdose were included. ResultsIn total, 3527 individuals were included in this study. There were 958 individuals who returned for refills 2303 times. Most participants were male (63.6%), with a history of opioid use (77.5%). Those who reported naloxone use were more likely to have a history of opioid use (aOR= 4.1; 95% CI=2.77,6.1), were younger (aOR=0.98; 95% CI=0.97,0.99) and had witnessed overdoses (aOR=3.3; 95% CI=1.98,5.34). Among current opioid users, the odds were higher for injectors (aOR=1.57; 95% CI=1.18,2.1). Naloxone use was reported 1282 times. Additional actions such as waking the person and calling the ambulance were frequently reported. Survival was reported in almost all cases (94%). ConclusionPeople who use drugs are a suitable target group for THN-programs, as they seem to be willing and capable to reverse overdoses effectively. Given their personal risk factors for overdosing, recipients will likely also benefit from overdose prevention education.

A rapid assessment of take-home naloxone provision during COVID-19 in Europe.

BackgroundIn March 2020, the World Health Organization declared COVID-19 a global pandemic. In the following weeks, most European countries implemented national lockdowns to mitigate viral spread. Services for people who use drugs had to quickly revise their operating procedures to rearrange service provision while adhering to lockdown requirements. Given the scarcity of literature published on overdose prevention during COVID-19 in Europe, we aimed to examine how these changes to service provision affected take-home naloxone (THN) programmes and naloxone availability across Europe.MethodsBetween November 2020 and January 2021, we conducted a rapid assessment with country experts from European countries that provide THN. We sent country experts a template to report monthly THN distribution data (January 1, 2019-October 31, 2020) and a structured 6-item survey for completion.ResultsResponses were received from 14 of the 15 European countries with THN provision of which 11 participated in the rapid assessment: Austria, Denmark, England, Estonia, Lithuania, Northern Ireland, Norway, Scotland, Spain (Catalonia only), Sweden, and Wales. All reported reduced organisational capacity during COVID-19, and some put into place a range of novel approaches to manage the restrictions on face-to-face service provision. In six countries, the introduction of programme innovation occurred alongside the publication of government guidelines recommending increased THN provision during COVID-19. Eight of the eleven participating countries managed to maintain 2019-level monthly THN distribution rates or even increase provision during the pandemic.ConclusionThrough programme innovation supported by public guidelines, many European THN programmes managed to ensure stable or even increased THN provision during the pandemic, despite social distancing and stay-at-home orders affecting client mobility.

Who is using take-home naloxone? An examination of supersavers

BackgroundAs the opioid overdose crisis persists and take-home naloxone (THN) programmes expand, it is important that the intervention is targeted towards those most likely to use it. We examined THN program participants to 1) describe those that return for refills, specifically those that reported multiple use (supersavers), and 2) to examine what rescuer characteristics were associated with higher rates of THN use.MethodsThis study included a cohort of consenting THN recipients from June 2014–June 2021 who completed initial and refill questionnaires from a widespread program in Norway. Age, gender, number of witnessed and experienced overdoses were assessed for associations with higher reported rates of THN use. ‘Supersavers’ reported 3 or more THN uses.ResultsA total of 1054 participants returned for a THN refill during the study period. Of these, 558 reported their last THN to have been used on an overdose. Supersavers (those that reported 3 or more THN uses) were younger, primarily reported current opioid use, and had witnessed higher rates of overdoses at the time of initial training when compared to non-supersavers (those that reported 0–2 THN uses).ConclusionsTHN programs should continue to emphasize and prioritize THN for people actively using drugs, particularly those who have witnessed overdoses previously.

Factors associated with take-home naloxone kit usage in British Columbia: an analysis of administrative data

BackgroundThe British Columbia (BC) Take-Home Naloxone (THN) program provides naloxone to people at risk of experiencing or witnessing an opioid overdose for use in reversing suspected overdose events. This study seeks to examine trends and correlates of individuals obtaining a THN kit in BC between 2017 and 2020.MethodsRecords of THN kits distributed between 2017 and 2020 were the primary source of data for this analysis. Frequency tables were used to describe characteristics of people obtaining kits from THN sites. Correlates of individuals obtaining a THN kit to replace a previous kit reported as used to reverse an overdose were assessed with multivariate logistic regression.ResultsBetween January 1, 2017, and December 31, 2020, 240,606 THN kits were reported distributed by registered sites to members of the public, with 90,011 records indicating that a kit was obtained to replace a previous kit that had been used to reverse an overdose. There was a significant trend in increasing kits reported used by year (p < 0.01). The kit recipient’s risk of overdose was a significant predictor of having reported using a THN kit, and the strength of the association was dependent on gender (Male: Adjusted odds ratio (AOR) 5.37 [95% confidence interval (CI) 5.08 – 5.67]; Female: AOR 8.35 [95% CI 7.90 – 8.82]; Trans and gender expansive: AOR 3.68 [95% CI 2.82 – 4.79]).ConclusionsBetween 2017 and 2020, THN kits were used to reverse tens of thousands of overdose events in BC, with people at risk of overdose (i.e. people who use drugs [PWUD]) having greater odds of using a kit to reverse an overdose than those not at risk. Thus, PWUD are responsible for reversing the vast majority of overdoses. THN kits are being distributed to the people who use them most. However, additional strategies in conjunction with community-based naloxone distribution programs are needed to address the rising number of illicit drug toxicity deaths.

Staff preferences towards electronic data collection from a national take-home naloxone program: a cross-sectional study

BackgroundDuring the scaling-up of a national Norwegian take-home naloxone (THN) program, data collection methods shifted from paper-based to electronic. The aim of this study was to explore staff preferences towards the shift in data collection.MethodsIn January–February 2020, a survey was sent out via email to personnel involved with the THN program (n = 200). The survey included 17 questions, and covered staff demographics, experiences distributing THN, preferences towards data collection (both paper and electronically), and an open response section. Descriptive statistics were performed for the survey results. The open response section was recorded from each questionnaire and was coded into major themes by the authors.ResultsIn total, 122 staff completed the survey. Of these, 62% had experience with both electronic and paper-based forms, and there was a near unanimous preference towards electronic data collection over paper-based forms. From the free-text responses, staff found the electronic form to be a useful tool for conversation and overdose prevention education, and that the electronic form was easier to manage than the paper forms.ConclusionThe shift towards electronic data collection was necessary for the feasibility of the Norwegian national THN program. This study found that staff not only tolerated the shift, but in most cases preferred this organizational change.

Piloting a statewide emergency department take-home naloxone program: Improving the quality of care for patients at risk of opioid overdose.

Emergency department (ED) patients with nonfatal opioid overdose are at high risk for subsequent fatal overdose, yet ED programs aimed at reducing harm from opioid use remain underdeveloped. The objective was to pilot a statewide ED take-home naloxone program and improve the care of patients with opioid use disorder (OUD) and risky drug use through training and interprofessional network building. Nine hospital EDs with pharmacy, nurse, and physician champions were recruited, surveyed, and trained. Take-home naloxone rescue kits were developed, disseminated, and tracked. Two overdose prevention summits were convened prior to the COVID pandemic, and two X-waiver training courses aimed at emergency physicians and advanced practice providers were arranged, both in person and virtual. A total of 872 naloxone rescue kits were distributed to ED patients at risk of opioid overdose during the first phase of this project, and more than 140 providers were trained in the use of medications for OUD in acute care settings. A statewide ED take-home naloxone program was shown to be feasible across a range of different hospitals with varying maturity in preexisting OUD resources and capabilities. Future work will be aimed at both expanding and measuring the effectiveness of this work.

Overdose and take-home naloxone in emergency settings: A pilot study examining feasibility of delivering brief interventions addressing overdose prevention with 'take-home naloxone' in emergency departments.

Although most unintentional opioid deaths in Australia are attributed to pharmaceutical opioids, take-home naloxone (THN) programmes have to date predominantly targeted people using illicit opioids in drug treatment and harm reduction settings. We sought to examine the feasibility of delivering THN brief interventions (THN-BIs) with intranasal naloxone in EDs. This pilot feasibility study was conducted across three major metropolitan EDs in Sydney and Melbourne. ED staff were surveyed about their perspectives regarding THN before completing a 30-min training programme in THN-BI delivery. Patients presenting with opioid overdose or considered high risk for future overdose were eligible to receive the THN-BI. Staff survey responses were compared between hospitals and provider types using one-way analysis of variances. Patient demographic and clinical characteristics were extracted from medical records and compared between hospitals and overdose type using Fisher's exact test and one-way analysis of variances. One hundred and twenty-two ED staff completed the survey. One hundred and ten (90.2%) agreed that EDs should provide THN-BIs, whereas 23 (19.2%) identified time constraints and 17 (12.9%) felt uncomfortable discussing overdose with patients. Fifty-seven patients received the THN-BI, with the majority (n= 50, 87.7%) having presented following opioid overdose. The median age was 44 years and 40 (71.4%) were men. Two-thirds of the overdoses (n= 31, 66.0%) were attributed to heroin with one-third (n= 16, 34%) being attributed to pharmaceutical opioids. ED-based delivery of THN-BIs can reach a wide range of individuals at-risk of overdose. The present study supports the feasibility of THN interventions in EDs and underscores the importance of addressing implementation barriers including staff training.
