It’s Risky Out Where We Are: Exploring Intersectional Factors of Intentional Overdose Among People Who Use Drugs in Regional Queensland, Australia

Objective Globally, drug-related deaths impact both urban and non-urban areas. In Australia, regional areas face a concerning rise in drug-induced fatalities and suicides, exacerbated by structural factors like limited services and stigma. We sought to explore the experiences of people who use drugs (PWUDs) in regional Queensland to understand the structural vulnerabilities influencing drug-induced deaths. Methods The sample comprised 19 PWUDs from regional Queensland, Australia who had experienced overdose. Semi-structured interviews explored participants’ overdose experiences and contributing factors, focusing on regionality. Iterative coding was used to develop thematic categories. Results Participants highlighted the complex interplay of trauma, coping and drug use influencing overdose dynamics. Regional challenges, including limited access to support services, exacerbate risks for PWUDs. Structural inequalities perpetuate cycles of harm, with rural areas disproportionately affected. Participants emphasized the need for systemic changes to facilitate effective suicide prevention efforts, advocating for enhanced service engagement and legislative reforms. Conclusions These findings challenge systemic factors such as stigma and healthcare accessibility, which appear to be driving drug-related harm. Based on the findings, recommendations are made for systemic change, represented by comprehensive, community-driven interventions to address structural inequalities, and improve access to support services.

Characterizing Individuals Who Elect and Decline Opioid Overdose Education and Naloxone Distribution to Tailor Programs and Expand Impact.

In response to the opioid epidemic, federal agencies have stressed the importance of targeted naloxone distribution through avenues such as Opioid Overdose Education and Naloxone Distribution (OEND). OEND effectively reduces mortality by training laypersons to respond to overdose situations. Despite demonstrated effectiveness, OEND remains underutilized. This project aimed to characterize those who illicitly use opioids to determine avenues for future tailoring of OEND programs. Individuals who illicitly used opioids within the past 6 months were recruited via online social media. Participants completed an online questionnaire that assessed history of opioid use and were given the option to receive opioid overdose and naloxone administration training. Those who elected training (n = 111) and those who declined (n = 193) were compared on opioid use, severity of use, and overdose experiences. Participants (N = 304) were 47% male and 83% White. Tests of between group differences with measures of effect size were used for analyses. Those who elected training endorsed greater intravenous administration (χ2 = 4.18, P = 0.041, Cramer's V = 0.12). Individuals who declined training reported more frequent nonprescribed methadone use (χ2 = 7.51, P = 0.006, Cramer's V = 0.16), overdose hospitalizations (t(298) = 2.13, P = 0.034, Cohen's d = 0.26), and observed overdoses (t(300) = 3.01, P = 0.003, Cohen's d = 0.36). After adjusting for multiple comparisons, only the differences in nonprescribed methadone use and observed overdoses remained statistically significant. Individuals who declined training were more likely to report ever use of nonprescribed methadone and having witnessed others overdose. They may have had greater exposure to naloxone, hence decreasing perceived need for training. Understanding characteristics of those who elect and refuse training could inform structuring of programs and recruitment approaches.

Protective Factors Associated With Lower Likelihood of Injection Drug Use and Experiencing Overdose Among Incarcerated Women

PurposePrior studies evaluated protective factors individually as they relate to fewer drug use risk behaviors and related consequences. This is the first study to examine protective factors as part of a multilevel framework along a risk continuum among women involved in the criminal legal system who use drugs. This study describes factors within the socio-ecological framework that are protective against engaging in injection drug use and experiencing nonfatal overdose. MethodData were collected from 900 women with a history of opioid use disorder who were incarcerated and enrolled in the National Institutes of Health/National Institute on Drug Abuse–funded Justice Community Opioid Innovation Network cooperative. Analysis focused on the relationship among individual, interpersonal, and community- or institutional-level protective factors associated with not injecting drugs and not experiencing an overdose in the 90 days before incarceration using multinomial logistic regression. FindingsFindings from this study suggest that, even among a sample of women who use drugs, there are a number of factors associated with being less likely to report higher-risk injection behavior and/or overdose experiences at the individual level (age, religiosity, and less polysubstance use), interpersonal level (not having a partner who injects drugs), and community or institutional level (fewer months incarcerated, less treatment utilization, and less enacted stigma by health care workers). ConclusionsFindings from this study underscore the importance of being able to target prevention interventions to women at different stages of substance use severity and to capitalize on protective factors for those at lower-risk levels to reduce the trajectory of risk of injection practices and overdose experiences.

Harm Reduction and Treatment Among People at High Risk of Overdose

Rates of overdose deaths involving synthetic opioids remain high, increasingly involve stimulants combined with opioids, and are increasing rapidly in racially and ethnically minoritized communities, yet little is known about access to harm reduction and treatment services in these groups. To characterize access and barriers to harm reduction and treatment in a racially and ethnically diverse population of people who use drugs. A cross-sectional telephone survey of people recruited from 39 treatment, harm reduction, and social service organizations in Milwaukee County, Wisconsin; Flint and Detroit, Michigan; and statewide in New Jersey was conducted from January 30 to July 28, 2023. Adults who used cocaine, methamphetamine, or opioids in the past 30 days called a study hotline and completed an interview in English or Spanish. Overdose experience, drug types used (opioids only, stimulants only, and polysubstance), and social risk factors (eg, financial instability and criminal legal involvement). Recent use of any harm reduction services, fentanyl test strips, naloxone possession, treatment, and self-reported barriers to services. Of the total sample of 1240 adults, 486 (39.2%) were Black non-Hispanic, 183 (14.8%) were Hispanic, and 464 (37.4%) were White non-Hispanic. In the past 30 days, 826 individuals (66.6%) were polysubstance users, 135 (10.9%) used only opioids, and 279 (22.5%) used only stimulants. A total of 349 respondents (28.1%) experienced a prior-year overdose. Compared with those without a prior-year overdose, people with overdose were more likely to possess naloxone (80.7% vs 68.2%; P < .001), possess fentanyl test strips (36.8% vs 23.5%; P < .001), and use harm reduction services (63.4% vs 53.0%; P = .003), while differences in treatment use were nonsignificant (52.0% vs 46.6%; P = .24). Among stimulant-only users, 51.4% possessed naloxone compared with 77.3% of opioid-only users (P < .001) and 77.6% of polysubstance users (P < .001), with similar disparities in fentanyl test strip possession. In this cross-sectional study of people who used drugs in the past 30 days, findings highlighted low use of harm reduction and treatment services among people who use stimulants. Additional communication regarding their importance may help increase the use of the services amidst a rapidly changing drug supply.

Overdose Experiences Among a Sample of Women in Jail with Opioid Use Disorder

Background: Previous non-fatal overdose may increase risk of overdose fatality for women reentering the community following incarceration, but pre-incarceration overdose experiences are understudied. This study describes the prevalence and correlates of non-fatal overdose prior to jail among women with opioid use disorder (OUD). Methods: Women (N = 700) were randomly selected from eight Kentucky jails, screened for OUD, and interviewed as part of the NIDA-funded Kentucky Justice Community Opioid Innovation Network (JCOIN) trial. Descriptive statistics were used to examine women’s prior overdose experiences, while bivariate analyses and logistic regression were used to identify correlates of overdose in the 90 days prior to jail. Results: Analyses found that 55.4% of women had overdosed in their lifetime, and 21.4% overdosed in the 90 days prior to jail. Of those who overdosed in the 90 days prior to jail, heroin (80.7%) was the most-commonly used drug prior to overdose, 35.2% received emergency, medically-attended services post-overdose, and 92.4% were administered naloxone – primarily by acquaintances. Overdosing in the 90 days prior to jail was positively correlated with identifying as a sexual minority, being from an urban community, childhood victimization, as well as recent heroin, fentanyl, and injection drug use. Conclusions: Findings indicate that prior overdose is common among jailed women with OUD, and although naloxone was often administered, few women received medically-attended services post-overdose. Results highlight the importance of distributing naloxone to community members and women reentering the community from jail, and suggest additional research is needed to understand factors inhibiting medical care following an overdose.

"We only trust each other": A qualitative study exploring the overdose risk environment among persons who inject drugs living with HIV in Nairobi, Kenya.

In Kenya, overdose remains a major public health concern with approximately 40% of persons who inject drugs (PWID) reporting personal overdoses. PWID living with HIV (PWID-LH) are particularly vulnerable to experiencing fatal and non-fatal overdoses because of the surrounding physical, social, economic, and political environments, which are not fully understood in Kenya. Through qualitative inquiry, this study characterizes Kenya's overdose risk environment. Participants were purposively recruited from a larger cohort study from September to December 2018 using the following inclusion criteria: HIV-positive, age ≥18 years, injected drugs in the last year, and completed cohort study visits. Semi-structured interviews explored experiences of personal and observed overdoses, including injection settings, sequence of events (e.g., pre-, during, and post-overdose), safety strategies, and treatment. Interviews were transcribed, translated (Swahili to English), reviewed, and analyzed thematically, applying a risk environment framework. Nearly all participants described personal and/or observed overdose experiences (96%) and heroin was the most frequently reported substance (79%). Overdose precursors included increased consumption, polysubstance use, recent incarceration, and rushed injections. There were also indications of female-specific precursors, including violence and accessing prefilled syringes within occupational settings. Overdose safety strategies included avoiding injecting alone, injecting drugs incrementally, assessing drug quality, and avoiding polysubstance use. Basic first-aid techniques and naloxone use were common treatment strategies; however, naloxone awareness was low (25%). Barriers to treatment included social network abandonment, police discrimination, medical stigma, fatalism/religiosity, medical and transportation costs, and limited access to treatment services. In Kenya, the overdose risk environment highlights the need for comprehensive overdose strategies that address the physical, social, economic, and political environments. Morbidity and mortality from overdose among PWID-LH could be reduced through overdose prevention initiatives that support harm reduction education, naloxone awareness, and access, destigmatization of PWID, and reforming punitive policies that criminalize PWID-LH.

A qualitative study examining the experiences of people who use drugs in supportive housing in London, Ontario

Background Since 2016, London, Ontario has experienced increasing numbers of opioid overdoses and overdose related deaths. Supportive housing agencies have been especially impacted, experiencing an 890% increase in opioid overdose from 2018-2021. A coalition was formed between London housing agencies and our research team to better understand the perspective of precariously housed participants who use drugs on existing substance use and overdose related policies within housing agencies. We aimed to center participant voices in policy development efforts. Methods Using a community-based participatory research framework, 17 participants were interviewed at three housing agencies. Drawing on qualitative descriptive methods, transcripts were subject to content analysis and three themes were identified. Results Themes included (1) conflicts between agency rules and resident realities, (2) safe use accessibility, (3) trust and understanding key to facilitating harm reduction. Conclusion Trust and understanding were weaved across all themes and mediated participants’ opioid overdose experience and risk of overdose related deaths. We recommend interventions to rebuild trust and foster understanding alongside harm reduction-based policies to reduce overdose related deaths.

A qualitative study on perceptions and experiences of overdose among people who smoke drugs in Vancouver, British Columbia

BackgroundSmoking unregulated drugs has increased substantially in British Columbia. Intersecting with the ongoing overdose crisis, drug smoking-related overdose fatalities have correspondingly surged. However, little is known about the experiences of overdose among people who smoke drugs accessing the toxic drug supply. This study explores perceptions and experiences of overdose among people who smoke drugs. MethodsWe conducted interviews with 31 people who smoke drugs. Interviews covered a range of topics including overdose experience. Thematic analysis was used to identify themes related to participant perceptions and experiences of smoking-related overdose. ResultsSome participants perceived smoking drugs to pose lower overdose risk relative to injecting drugs. Participants reported smoking-related overdose experiences, including from underestimating the potency of drugs, the cross-contamination of stimulants with opioids, and responding to smoking-related overdose events. ConclusionsFindings highlight the impact the unpredictable, unregulated, and toxic drug supply is having on people who smoke drugs, both among people who use opioids, and among those who primarily use stimulants. Efforts to address smoking-related overdose could benefit from expanding supervised smoking sites, working with people who use drugs to disseminate accurate knowledge around smoking-related overdose risk, and offering a smokable alternative to the unpredictable drug supply.

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

BackgroundThe rising prevalence of fast-acting opioids in the USA suggests the increased need for non-professional first responder administration of naloxone. Effective administration of naloxone during an overdose requires that bystanders are familiar with, have access to, and know how to use naloxone.MethodsDrawing on a statewide, address-based sample of Nebraskan adults, we used logistic regression to predict the likelihood of respondents’ familiarity with, access to, and competency to administer naloxone. Our independent variables included measures indicating proximity to drug use, perceived community stigma toward people who use drugs, and demographic data.ResultsThere were significant gaps in naloxone knowledge in Nebraska. Although 74.8% of respondents were familiar with naloxone, only 18.2% knew how to access it and 18.0% knew how to use it. Being close to an overdose experience, lifetime illicit opioid use, being close to a person who uses opioids, and having access to illicit opioids were not significantly associated with naloxone familiarity, access, or competency among respondents in Nebraska’s two largest cities, Omaha and Lincoln. Outside of these cities, being close to a past overdose experience and access to illicit opioids was associated with higher odds of naloxone access and competency, but lifetime opioid use and being close to a person who uses opioids were not. Finally, among those familiar with naloxone, a higher perception of community stigma toward people who use opioids generally was associated with lower odds of naloxone access and competency. Higher perception of community stigma toward people who use heroin, methamphetamines, and cocaine, however, was associated with higher odds of naloxone access.ConclusionsOur findings highlight the continued need for education on naloxone with a specific focus on access and competency to further reduce opioid-related overdose deaths. Specific focus should be placed on promoting naloxone knowledge among people with a higher likelihood of needing to administer naloxone to reduce otherwise avoidable deaths. Further work is needed to understand differences in the relationship between substance-specific perceived stigma and its association with naloxone access.

Lifetime non-fatal overdose experiences among at-risk adolescents and young adults in the emergency department with past-year opioid use in the USA

BackgroundAdolescents and young adults with risk factors for opioid misuse and opioid use disorder are at elevated risk for overdose. We examined prior non-fatal overdose experiences among at-risk adolescents/young adults...

Associations with experience of non-fatal opioid overdose in British Columbia, Canada: a repeated cross sectional survey study

IntroductionLives lost in North America due to the unregulated drug poisoning emergency are preventable and those who survive an opioid overdose may suffer long-term disability. Rates of opioid overdose more than doubled following the onset of the COVID-19 pandemic in British Columbia, Canada.Materials and methodsOur analytical sample was comprised of 1447 participants from the 2018, 2019, and 2021 Harm Reduction Client Survey who responded yes or no to having experienced an opioid overdose in the past 6 months. Participants were recruited from harm reduction sites from across British Columbia. We used logistic regression to explore associations of experiencing an opioid overdose.ResultsOverall, 21.8% of participants reported experiencing an opioid overdose in the last six months (18.2% in 2019 and 26.6% in 2021). The following factors were positively associated with increased adjusted odds of experiencing a non-fatal opioid overdose: cis men relative to cis women (AOR 1.49, 95% CI 1.10–2.02), unstably housed compared to people with stable housing (AOR 1.87, 95% CI 1.40–2.50), and participants from 2021 compared to those from 2019 (AOR 3.06, 95% CI 1.57–5.97). The effects of both previous experience of a stimulant overdose and having witnessed an opioid overdose depended on the year of study, with both effects decreasing over subsequent years.ConclusionsOverdoses have increased over time; in 2021 more than one in four participants experienced an overdose. There is an urgent need for policy and program development to meaningfully address the unregulated drug poisoning emergency through acceptable life-saving interventions and services to prevent overdoses and support overdose survivors.

Fentanyl Exposure and Detection Strategies Utilized by Clinical Trial Participants Seeking Linkage to Opioid Use Disorder Treatment at a Syringe Service Program

IntroductionThe USA continues to face a fentanyl-driven overdose epidemic. Prior research has demonstrated users of illicit opioids are concerned about fentanyl exposure and overdose, but the strategies they report using to detect fentanyl’s presence lack empirical support. This study compares self-report and biologically detected fentanyl use and investigates overdose risk and risk reduction behaviors among a sample of high-risk people who use opioids.MethodsStructured enrollment interviews conducted as part of a larger clinical trial assessed self-reported fentanyl exposure as well as strategies used to determine believed fentanyl exposure and prevent overdose among 240 participants enrolled at a Chicago, IL syringe service program. Urinalysis measured actual fentanyl exposure.ResultsMost participants identified as African American (66.7%) and had considerable overdose experience (76.7% lifetime and 48% in the past year). Most also tested positive for fentanyl (93.75%) despite reporting no past year use of fentanyl or fentanyl-adulterated drugs (64.17%). The most utilized approaches reported for identifying fentanyl exposure were stronger effects of the drug (60.7%), sight or taste (46.9%), and being told by someone using the same drugs (34.2%). Few participants (14%) reported using fentanyl test strips. No significant associations were identified between self-report and urinalysis measures or urinalysis results and risk reduction strategies.ConclusionThis study adds to prior fentanyl exposure risk research. The disconnect between participants’ fentanyl detection methods and reported overdose experiences supports the need for more research to identify and understand factors driving access and use of overdose prevention resources and strategies.

Emergency Skills in Athletic Training: Perceived Knowledge and Continuing Education

Context Continuing education (CE) in health care, particularly in athletic training, often fails to meet the needs of its participants. Rapid increases in available information make it necessary for CE to be delivered as efficiently as possible. Objective To explore whether an interactive teaching strategy and various characteristics of athletic trainers affected the perceived knowledge of emergency skills among certified athletic trainers. Design Quasiexperimental study with a single-group pretest-posttest design. Patients or Other Participants Certified athletic trainers (N = 81) at the Great Lakes Athletic Trainers' Association Annual Meeting and Symposium. Intervention(s) Emergency skills practice session for anaphylaxis, opioid overdose, diabetes, and asthma. Main Outcome Measure(s) Participants completed a preintervention perceived knowledge questionnaire (PKQ) that included background information questions and completed a postintervention PKQ. Results A statistically significant difference (P &amp;lt; .001) in PKQ scores from pretest to posttest was found with pretest scores being lower than posttest scores (89.59 and 103.02, respectively). Age and years of experience had a weak correlation with PKQ pretest scores (rs = .32 and rs = .33, respectively). Participant characteristics including additional certification (P = .012), anaphylaxis experience (P = .036), opioid overdose experience (P &amp;lt; .001), diabetes experience (P = .025), and combined emergency experience (P = .029) had significantly different pretest PKQ scores. Conclusions The use of an interactive teaching strategy in CE and certain athletic trainer characteristics significantly affected athletic trainers' perceived knowledge of emergency skills.

High willingness to use overdose prevention sites among suburban people who use drugs who do not inject

IntroductionOverdose prevention sites (OPS) are evidence-based interventions to improve public health, yet implementation has been limited in the USA due to a variety of legal impediments. Studies in various US settings have shown a high willingness to use OPS among urban and rural people who inject drugs, but data among people who use drugs (PWUD) via non-injection routes of administration in suburban areas are lacking.MethodsWe utilized cross-sectional data from a sample of suburban PWUD who have not injected drugs in the past 3 months (N = 126) in Anne Arundel County, Maryland. We assessed PWUDs’ likelihood of using a hypothetical OPS and perceived potential barriers to accessing OPS. We tested for associations between sociodemographic characteristics, drug use, service access, and overdose experiences with willingness to utilize OPS.FindingsParticipants’ median age was 42, and the majority were men (67%) and non-Hispanic Black (79%). Sixty-six percent reported willingness to use an OPS. Concerns about confidentiality (29%), arrest (20%), and transportation costs (22%) were the most anticipated barriers to using OPS. Men (75% vs 55%, p = 0.015), participants who used heroin (53% vs 32%, p = 0.017), and participants who used multiple overdose prevention behaviors (e.g., using fentanyl test strips) (36% vs 19%, p = 0.006) were more likely to report willingness to use OPS.ConclusionMost suburban non-injecting PWUD in the sample were willing to use an OPS. OPS implementation strategies in suburban settings should be tailored to reach PWUD via non-injection routes of administration while meeting the unique needs of suburban contexts.

Factors associated with daily use of benzodiazepines/tranquilizers and opioids among people who use drugs.

Co-use of benzodiazepines and opioids significantly increases fatal overdose risk, yet few studies have examined co-use of these drugs when obtained both with and without a prescription. We examined associations of daily co-use of prescribed benzodiazepines/tranquilizers (BZD/TRQ) and prescribed and nonprescribed opioids among people who use street opioids (PWUO). PWUO (N = 417) were recruited from Baltimore City and neighboring Anne Arundel County, Maryland, and surveyed on sociodemographic characteristics, structural vulnerabilities, healthcare access and utilization, substance use, and overdose experiences. Multivariable logistic regression was used to identify factors associated with self-reported co-use. Participants were 46 years old on average, and predominantly Black (74%) males (62%). Daily co-use was reported by 22%. In multivariable analyses, odds of co-use were significantly higher among participants who did not have a high school degree/GED (adjusted odds ratio [aOR]: 1.71, 95% confidence interval [CI]: 1.02-2.88), endorsed receiving mental health treatment in the past 6 months (aOR: 2.13, 95%CI: 1.28-3.56), reported daily use of powdered cocaine (aOR: 3.57, 95% CI: 1.98-6.45), and synthetic cannabinoids (aOR: 3.11, 95% CI: 1.40-6.93). Odds of co-use were significantly lower among Black participants compared to white participants (aOR: 0.39, 95% CI: 0.19-0.82). Clinicians working with PWUO or who prescribe BZDs or opioids should screen patients who use cocaine or synthetic cannabinoids, have low level of educational attainment, or recently accessed mental health services, as these patients may be at higher risk for daily co-use of BZD/TRQ and opioids, and therefore lethal overdose.

"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.

Syndemic factors associated with non-fatal overdose among young opioid users in New York City.

Rates of illicit opioid use are particularly high among young adults, yet research on overdose experience and factors associated with overdose in this population remains limited. This study examines the experiences and correlates of non-fatal overdose among young adults using illicit opioids in New York City (NYC). 539 participants were recruited via Respondent-Driven Sampling in 2014-2016. Eligibility criteria included: aged 18-29 years old; current residence in NYC; and nonmedical prescription opioid (PO) use and/or heroin use in the past 30 days. Participants completed structured interviews to assess their socio-demographics, drug use trajectories, current substance use and lifetime and most recent overdose experiences, and were tested on-site for hepatitis C virus (HCV) antibodies. 43.9% of participants reported lifetime overdose experience; of these, 58.8% had experienced two or more overdose events. The majority of participants' most recent overdoses (63.5%) were due to polysubstance use. In bivariable analyses, after RDS adjustment, having ever overdosed was correlated with: household income of >$100,00 growing up (vs. $51,000-100,000); lifetime homelessness; HCV antibody-positive status; lifetime engagement in regular nonmedical benzodiazepine use, regular heroin injection and regular PO injection; and using a non-sterile syringe in the past 12 months. Multivariable logistic regression identified childhood household income >$100,00 (AOR=1.88), HCV-positive status (AOR=2.64), benzodiazepine use (AOR=2.15), PO injection (AOR=1.96) and non-sterile syringe use (AOR=1.70) as significant independent correlates of lifetime overdose. A multivariable model with multiple overdoses (vs. one) found only lifetime regular heroin use and PO injection to be strong correlates. Results indicate a high prevalence of lifetime and repeated overdose among opioid-using young adults in NYC, highlighting a need for intensified overdose prevention efforts for this population. The strong associations of HCV and indices of polydrug use with overdose suggest that prevention efforts should address the complex risk environment in which overdose occurs, attending to the overlapping nature of disease-related risk behavior and overdose risk behavior among young people who inject opioids. Overdose prevention efforts tailored for this group may find it useful to adopt a syndemic conception of overdose that understands such events as resulting from multiple, and often interrelated, risk factors.

Intersections between syndemic conditions and stages along the continuum of overdose risk among women who inject drugs in Mexicali, Mexico

BackgroundResearch on women who inject drugs is scarce in low- and middle-income countries. Women experience unique harms such as sexism and sexual violence which translate into negative health outcomes. The present work aims to provide insight into the experiences of women who inject drugs at the US–Mexico border to identify social and health-related risk factors for overdose to guide harm reduction interventions across the Global South.MethodsWe recruited 25 women ≥ 18 years of age accessing harm reduction and sexual health services at a non-governmental harm reduction organization, “Verter”, in Mexicali, Mexico. We employed purposeful sampling to recruit women who inject drugs who met eligibility criteria. We collected quantitative survey data and in-depth interview data. Analyses of both data sources involved the examination of descriptive statistics and thematic analysis, respectively, and were guided by the syndemic and continuum of overdose risk frameworks.ResultsSurvey data demonstrated reports of initiating injection drug use at a young age, experiencing homelessness, engaging in sex work, being rejected by family members, experiencing physical violence, injecting in public spaces, and experiencing repeated overdose events. Interview data provided evidence of stigma and discrimination toward women, a lack of safe spaces and support systems, risk of overdose-related harms, sexual violence, and the overall need for harm reduction services.ConclusionWomen who inject drugs in Mexicali describe experiences of violence, overdose, and public injecting. Women are particularly vulnerable in the Mexicali context, as this area faces a noticeable lack of health and social services. Evidenced-based harm reduction strategies such as safe consumption sites and overdose prevention strategies (e.g., naloxone distribution and training) may benefit this population. Evidence from local organizations could help close the gap in service provision in low-resource settings like Mexico, where government action is almost nonexistent.

Non-fatal drug overdose among persons who inject drugs during first two years of the COVID-19 pandemic in New York City: Prevalence, risk factors

BackgroundWe examined non-fatal drug overdoses during the COVID-19 pandemic among persons who inject drugs (PWID) in New York City (NYC). MethodsWe recruited 275 PWID through respondent driven sampling and staff outreach from Oct. 2021-Sept. 2022 and enrolled in a cross-sectional survey. Information was collected on demographics, drug use behaviors, overdose experiences, substance use treatment history and strategies for coping with overdose threat. We compared PWID who did and did not experience non-fatal overdoses during lifetime and during the COVID-19 pandemic. ResultsParticipants were 71% male, and the mean age was 49 (SD 10). Heroin was the most frequently reported drug used (79%), 82% were fentanyl positive at enrollment urinalysis, 60% had overdosed in their lifetime and 34% had overdosed during the COVID-19 pandemic. In multivariable logistic regression, having previous overdosed, having a received a psychiatric diagnosis, and having a regular group of injectors were independently associated with experiencing an overdose during the pandemic. Overdose during the pandemic was unexpectedly high (approximately 30%) among persons reporting less than daily use of their main drug. Among PWID, 95% reported practicing at least one and 75% at least two overdose coping strategies. Practicing the different strategies, however, was generally not associated with a lower probability of experiencing an overdose. ConclusionsThere has been a high rate of non-fatal overdoses among PWID in NYC during the pandemic. Fentanyl is almost ubiquitous in the drug supply in the city. PWID coping strategies are not yet providing strong protective effects against non-fatal overdose.

Considerations for the design of overdose education and naloxone distribution interventions: results of a multi-stakeholder workshop

IntroductionOpioid overdose epidemic is a public health crisis that is impacting communities around the world. Overdose education and naloxone distribution programs equip and train lay people to respond in the event of an overdose. We aimed to understand factors to consider for the design of naloxone distribution programs in point-of-care settings from the point of view of community stakeholders.MethodsWe hosted a multi-stakeholder co-design workshop to elicit suggestions for a naloxone distribution program. We recruited people with lived experience of opioid overdose, community representatives, and other stakeholders from family practice, emergency medicine, addictions medicine, and public health to participate in a full-day facilitated co-design discussion wherein large and small group discussions were audio-recorded, transcribed and analysed using thematic approaches.ResultsA total of twenty-four participants participated in the multi-stakeholder workshop from five stakeholder groups including geographic and setting diversity. Collaborative dialogue and shared storytelling revealed seven considerations for the design of naloxone distribution programs specific to training needs and the provision of naloxone, these are: recognizing overdose, how much naloxone, impact of stigma, legal risk of responding, position as conventional first aid, friends and family as responders, support to call 911.ConclusionTo create an naloxone distribution program in emergency departments, family practice and substance use treatment services, stigma is a central design consideration for training and naloxone kits. Design choices that reference the iconography, type, and form of materials associated with first aid have the potential to satisfy the need to de-stigmatize overdose response.
