Circumstances of overdose among street-involved, opioid-injecting women: Drug, set, and setting

Risk mitigation guidance and safer supply prescribing among young people who use drugs in the context of COVID-19 and overdose emergencies

Across North America, overlapping overdose and COVID-19 emergencies have had a substantial impact on young people who use drugs (YPWUD). New risk mitigation guidance (RMG) prescribing practices were introduced in British Columbia, Canada, in 2020 to allow people to decrease risk of overdose and withdrawal and better self-isolate. We examined how the prescribing of hydromorphone tablets specifically impacted YPWUD's substance use and care trajectories. Between April 2020 and July 2021, we conducted virtual interviews with 30 YPWUD who had accessed an RMG prescription of hydromorphone in the previous six months and 10 addiction medicine physicians working in Vancouver. A thematic analysis was conducted. YPWUD participants highlighted a disjuncture between risk mitigation prescriptions and the safe supply of unadulterated substances such as fentanyl, underscoring that having access to the latter is critical to reducing their reliance on street-based drug markets and overdose-related risks. They described re-appropriating these prescriptions to meet their needs, stockpiling hydromorphone so that it could be used as an “emergency backup” when they were unable to procure unregulated, illicit opioids. In the context of entrenched poverty, hydromorphone was also used to generate income for the purchase of drugs and various necessities. For some YPWUD, hydromorphone prescriptions could be used alongside opioid agonist therapy (OAT) to reduce withdrawal and cravings and improve adherence to OAT. However, some physicians were wary of prescribing hydromorphone due to the lack of evidence for this new approach. Our findings underscore the importance of providing YPWUD with a safe supply of the substances they are actively using alongside a continuum of substance use treatment and care, and the need for both medical and community-based safe and safer supply models.

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

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSION

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".

Pathways connecting socioeconomic marginalization and overdose: A qualitative narrative synthesis

PURPOSE

This qualitative narrative synthesis sought to identify pathways connecting socioeconomic marginalization (SEM) and overdose for people who use drugs.

METHODS

We included studies with qualitative examination of SEM and fatal and non-fatal overdose published in English between 2000 and 2021. Studies were systematically identified and screened by searching MEDLINE (Ovid), Embase (Ovid), PsycINFO (EBSCOhost), CINAHL (EBSCOhost), Google Scholar, Cochrane Central Registry of Controlled Trials (CENTRAL), and Cochrane Drug and Alcohol Group (CDAG) Specialized Registry, citations, and contacting experts. Risk of bias and quality assessments were performed using the Critical Appraisal Skills Programme checklist and the Confidence in the Evidence from Reviews of Qualitative Research approach. Data were synthesized using a thematic synthesis approach.

RESULTS

The primary search strategy found 5909 articles that met the initial screening criteria. The review and screening process led to a final dataset of 27 qualitative articles. The four key findings of this narrative synthesis revealed aspects of SEM which shaped drug poisoning risk for people who use drugs: (1) resource insufficiency, labor market exclusion and deindustrialization, (2) homelessness and housing, (3) policing, criminalization, and interactions with emergency services, and (4) gendered and racialized dimensions of inequality. Findings led to creating a typology that includes material, behavioral, psychological, social, and environmental pathways that contain multiple mechanisms connecting SEM to overdose. This review revealed reciprocal connections between overdose and SEM via institutional pathways with reinforcing mechanisms, and interrelationships present within and between pathways. Quality assessments indicated moderate confidence in three of four findings (Findings 2,3, and 4 above) and high confidence in one finding (Finding 1).

CONCLUSION

SEM is strongly linked to drug poisoning, and the mechanisms establishing these connections can be classified within four pathways. The interconnectedness of these mechanisms can lead to intensification of overdose risk and reinforcement of SEM itself.

Specific polysubstance use patterns predict relapse among patients entering opioid use disorder treatment

Introduction

While polysubstance use has consistently been associated with higher rates of relapse, few studies have examined subgroups with specific combinations and time course of polysubstance use (i.e., polysubstance use patterns). This study aimed to classify and compare polysubstance use patterns, and their associations with relapse to regular opioid use in 2637 participants in three large opioid use disorder (OUD) treatment trials.

Methods

We explored the daily patterns of self-reported substance use in the 28 days prior to treatment entry. Market basket analysis (MBA) and repeated measure latent class analysis (RMLCA) were used to examine the subgroups of polysubstance use patterns, and multiple logistic regression was used to examine associations between identified classes and relapse.

Results

MBA and RMLCA identified 34 "associations rules " and 6 classes, respectively. Specific combinations of polysubstance use and time course (high baseline use and rapid decrease of use prior to initiation) predicts a worse relapse outcome. MBA showed individuals who co-used cocaine, heroin, prescription opioids, and cannabis had a higher risk for relapse (OR = 2.82, 95%CI = 1.13, 7.03). In RMLCA, higher risk of relapse was observed in individuals who presented with high baseline prescription opioid (OR = 1.9, 95% CI = 1.3, 2.76) or heroin use (OR = 3.54, 95%CI = 1.86, 6.72), although use decreased in both cases prior to treatment initiation.

Conclusions

Our analyses identified subgroups with distinct patterns of polysubstance use. Different patterns of polysubstance use differentially predict relapse outcomes. Interventions tailored to these individuals with specific polysubstance use patterns prior to treatment initiation may increase the effectiveness of relapse prevention.

Receipt of Telehealth Services, Receipt and Retention of Medications for Opioid Use Disorder, and Medically Treated Overdose Among Medicare Beneficiaries Before and During the COVID-19 Pandemic

IMPORTANCE

Federal emergency authorities were invoked during the COVID-19 pandemic to expand use of telehealth for new and continued care, including provision of medications for opioid use disorder (MOUD).

OBJECTIVE

To examine receipt of telehealth services, MOUD (methadone, buprenorphine, and extended-release [ER] naltrexone) receipt and retention, and medically treated overdose before and during the COVID-19 pandemic.

DESIGN, SETTING, AND PARTICIPANTS

This exploratory longitudinal cohort study used data from the US Centers for Medicare & Medicaid Services from September 2018 to February 2021. Two cohorts (before COVID-19 pandemic from September 2018 to February 2020 and during COVID-19 pandemic from September 2019 to February 2021) of Medicare fee-for-service beneficiaries 18 years and older with an International Statistical Classification of Diseases, Tenth Revision, Clinical Modification OUD diagnosis.

EXPOSURES

Pre-COVID-19 pandemic vs COVID-19 pandemic cohort demographic characteristics, medical and substance use, and psychiatric comorbidities.

MAIN OUTCOMES AND MEASURES

Receipt and retention of MOUD, receipt of OUD and behavioral health-related telehealth services, and experiencing medically treated overdose.

RESULTS

The pre-COVID-19 pandemic cohort comprised 105 240 beneficiaries; of these, 61 152 (58.1%) were female, 71 152 (67.6%) were aged 45 to 74 years, and 82 822 (79.5%) non-Hispanic White. The COVID-19 pandemic cohort comprised 70 538 beneficiaries; of these, 40 257 (57.1%) were female, 46 793 (66.3%) were aged 45 to 74 years, and 55 510 (79.7%) were non-Hispanic White. During the study period, a larger percentage of beneficiaries in the pandemic cohort compared with the prepandemic cohort received OUD-related telehealth services (13 829 [19.6%] vs 593 [0.6%]; P < .001), behavioral health-related telehealth services (28 902 [41.0%] vs 1967 [1.9%]; P < .001), and MOUD (8854 [12.6%] vs 11 360 [10.8%]; P < .001). The percentage experiencing a medically treated overdose during the study period was similar (18.5% [19 491 of 105 240] in the prepandemic cohort vs 18.4% [13 004 of 70 538] in the pandemic cohort; P = .65). Receipt of OUD-related telehealth services in the pandemic cohort was associated with increased odds of MOUD retention (adjusted odds ratio [aOR], 1.27; 95% CI, 1.14-1.41) and lower odds of medically treated overdose (aOR, 0.67; 95% CI, 0.63-0.71). Among beneficiaries in the pandemic cohort, those receiving MOUD from opioid treatment programs only (aOR, 0.54; 95% CI, 0.47-0.63) and those receiving buprenorphine from pharmacies only (aOR, 0.91; 95% CI, 0.84-0.98) had lower odds of medically treated overdose compared with beneficiaries who did not receive MOUD.

CONCLUSIONS AND RELEVANCE

Emergency authorities to expand use of telehealth and provide flexibilities for MOUD provision during the pandemic were used by Medicare beneficiaries initiating an episode of OUD-related care and were associated with improved retention in care and reduced odds of medically treated overdose. Strategies to expand provision of MOUD and increase retention in care are urgently needed.

Endogenous opiates and behavior: 2020

This paper is the forty-third consecutive installment of the annual anthological review of research concerning the endogenous opioid system, summarizing articles published during 2020 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides and receptors as well as effects of opioid/opiate agonists and antagonists. The review is subdivided into the following specific topics: molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors (1), the roles of these opioid peptides and receptors in pain and analgesia in animals (2) and humans (3), opioid-sensitive and opioid-insensitive effects of nonopioid analgesics (4), opioid peptide and receptor involvement in tolerance and dependence (5), stress and social status (6), learning and memory (7), eating and drinking (8), drug abuse and alcohol (9), sexual activity and hormones, pregnancy, development and endocrinology (10), mental illness and mood (11), seizures and neurologic disorders (12), electrical-related activity and neurophysiology (13), general activity and locomotion (14), gastrointestinal, renal and hepatic functions (15), cardiovascular responses (16), respiration and thermoregulation (17), and immunological responses (18).

Trends in Mortality From Novel Psychoactive Substances as "Legal Highs": Gender Differences in Manner of Death and Implications for Risk Differences for Women

Introduction

This study aimed to examine drug-related deaths in the UK in which novel psychoactive substances (NPS) are an implicated substance, and to focus on female deaths in comparison with male deaths. While male overdoses dominate epidemiological statistics, there is an increase in female drug-related deaths and a narrowing of the gap between gender mortality rates which is to date unexplained.

Method

This study analyzed data from the National Programme for Substance Abuse Deaths (NPSAD) database that records drug-related deaths in the UK from coronial records. A dataset was constructed using parameters to capture all drug-related cases during the period 2007-2017 when NPS were legal and highly available in the UK, in order to capture deaths recorded among both regular and occasional drug users, and to include all cases recorded during that period regardless of NPS status in order to make comparisons. The final dataset comprised 10,159 cases, with 456 NPS-related deaths. Data for NPS and non-NPS were compared, and comparisons were made between cohorts by gender. The dataset also includes coronial narrative notes which allowed a qualitative analysis of NPS female deaths to add contextual explanation.

Results

The proportion of male NPS deaths is significantly higher than that for female NPS deaths but does not reflect the generalized difference between male and female drug-related mortality of this period studied. Demographic and outcome data by gender difference were significant for all drug-related deaths, but not for NPS-only deaths, indicating a greater homogeneity among NPS deaths by gender. Older women using NPS were more likely to have methadone or diazepam as another drug implicated and have established histories of drug misuse.

Conclusion

Where NPS have been used, differences in drug death profiles are less likely to be accounted for by gender than other demographic or behavioral differences more typically found in opiate deaths. The social and health problems of older women may be key characteristics that differentiate female deaths from male deaths. These findings also support evidence of increasing uptake of NPS among older established drug users that adds further risk to polydrug use.

Miscarriage and Abortion Among Women Attending Harm Reduction Services in Philadelphia: Correlations With Individual, Interpersonal, and Structural Factors

Background: Reproductive health research among women who use drugs has focused on pregnancy prevention and perinatal/neonatal outcomes, but there have been few investigations of miscarriage and abortion, including prevalence and associated factors. Methods: Using cross-sectional data from a sample of non-pregnant women receiving harm reduction services in Philadelphia in 2016-2017 we examined lifetime miscarriage and abortion (n = 187). Separately for both outcomes, we used modified Poisson regression to estimate prevalence ratios (PR) and 95% confidence intervals (CI) for associations with each correlate. We also explored correlates of reporting both miscarriage and abortion. Results: Approximately 47% experienced miscarriage, 42% experienced abortion, and 18% experienced both. Miscarriage correlates included: prescription opioid misuse (e.g., OxyContin PR 1.82, 95% CI 1.23, 2.69); 40% increase in prevalence associated with housing instability, 50% increase with survival sex, and two-fold increase with arrest. Abortion correlates included: mental health (e.g., depression PR 2.09, 95% CI 1.18, 3.71), stimulant use (e.g., methamphetamine PR 1.83, 95% CI 1.22, 2.74), and drug injection (PR 1.76, 95% CI 1.03, 3.02); partner controlling access to people/possessions, physical and emotional violence; and a two-fold increase associated with survival sex and arrest. Experiencing both reproductive outcomes was correlated with mental health, opioid and simulant use, housing instability, survival sex, and arrest. Conclusion: Miscarriage and abortion was common among women with history of drug misuse suggesting a need for expanded access to family planning, medication-assisted therapy, and social support services, and for the integration of these with substance use services. Future research in longitudinal data is needed.

The Association of Drug-Use Characteristics and Active Coping Styles With Positive Affect in Patients With Heroin-Use Disorder and Methamphetamine-Use Disorder During the COVID-19 Pandemic

Background: Positive affect (PA) is crucial for individuals to cope with the current pandemic and buffer the lingering fears after it, especially for patients with substance-use disorders (SUDs). The current study aimed to explore PA and its related factors during the COVID-19 pandemic in male patients with the heroin-use disorder (HUD) and patients with the methamphetamine-use disorder (MAUD), respectively.

Methods: A total of 325 male patients with SUDs (106 with HUD and 219 with MAUD, all were single-substance users) in a compulsory rehabilitation center underwent semi-structured interviews during the pandemic. The demographic information, drug-use characteristics, active coping styles (ACSs, by Simple Coping Style Questionnaire), and PA (by the Positive and Negative Affect Scale) of participants were collected and recorded.

Results: There were significant differences between the two groups in age, the proportion of full-time workers before the epidemic, duration of drug use, the proportion of patients with long-term withdrawal during the epidemic, cravings, ACS, and PA. Correlation and multiple linear regression analysis showed that duration of drug use, ACS, and stable jobs were significant predictive factors for PA in patients with HUD, while long-term withdrawal, ACS, and stable jobs during the epidemic were significant predictive factors for PA in patients with MAUD.

Conclusions: Our study demonstrated the factors for PA in patients with HUD and MAUD during the pandemic. The results provided a basis for the comprehensive understanding of the PA of patients with SUDs and the development of targeted treatments.

Lay knowledge and practices of methamphetamine use to manage opioid-related overdose risks

AIM

Methamphetamine use has increased among individuals with opioid use disorder. The key aims of this study are to detail and contextualise lay knowledge, attitudes, and behaviours related to methamphetamine use in relation to opioid overdose risks in an area dominated by non-pharmaceutical fentanyl-type drugs (NPF).

METHODS

The study recruited 41 individuals in Dayton, Ohio, who reported past 30-day use of methamphetamine and heroin/fentanyl. Interviews included structured and qualitative questions. Urine toxicology analysis was conducted to identify NPFs and other drugs. Open-ended interview sections were audio-recorded, transcribed, and analysed qualitatively using NVivo.

RESULTS

The mean age was 38.3 years, 51% were female, and 100% non-Hispanic white. Participants described an exceedingly unpredictable local opioid market that became saturated with NPFs. The sample tested positive for 10 NPFs, including fentanyl (100%), acetyl fentanyl (61%), tetrahydrofuran fentanyl (29%), and carfentanil (12%). Most participants believed that methamphetamine could help prevent and/or reverse an opioid-related overdose. Nearly half had personally used it to help manage overdose risks related to NPF. These beliefs were embedded in a lay understanding of how methamphetamine works to stimulate the cardiovascular system. They were acted upon in the context of last resort situations that were determined by a lack of immediate access to naloxone, ambiguities surrounding overdose symptomatology, and easy access to plentiful and inexpensive methamphetamine.

CONCLUSION

Lay efforts to rely on methamphetamine to manage NPF-related overdose risks highlight the need for a continuing expansion of take-home-naloxone programs and implementation of other novel harm reduction approaches in communities affected by NPFs.

Characteristics and correlates of U.S. clinicians prescribing buprenorphine for opioid use disorder treatment using expanded authorities during the COVID-19 pandemic

BACKGROUND

To determine how clinicians with a DATA waiver to prescribe buprenorphine for opioid use disorder (OUD) adapted during the COVID-19 pandemic to emergency authorities, including use of telehealth to prescribe buprenorphine, the challenges faced by clinicians, and strategies employed by them to manage patients with OUD.

METHODS

From June 23, 2020 to August 19, 2020, we conducted an electronic survey of U.S. DATA-waivered clinicians. Descriptive statistics and multivariable logistic regression were used for analysis.

RESULTS

Among 10,238 respondents, 68 % were physicians, 25 % nursing-related providers, and 6% physician assistants; 28 % reported never prescribing or not prescribing in the 12 months prior to the survey. Among the 72 % of clinicians who reported past 12-month buprenorphine prescribing (i.e. active practitioners during the pandemic) 30 % reported their practice setting closed to in-person visits during COVID-19; 33 % reported remote prescribing to new patients without an in-person examination. The strongest predictors of remote buprenorphine prescribing to new patients were prescribing buprenorphine to larger numbers of patients in an average month in the past year and closure of the practice setting during the pandemic; previous experience with remote prescribing to established patients prior to COVID-19 also was a significant predictor. Among clinicians prescribing to new patients without an in-person examination, 5.5 % reported difficulties with buprenorphine induction, most commonly withdrawal symptoms.

CONCLUSIONS

Telehealth practices and prescribing to new patients without an in-person examination were adopted by DATA-waivered clinicians during the first six months of COVID-19. Permanent adoption of these authorities may enable expanded access to buprenorphine treatment.

Circumstances of overdose among suburban women who use opioids: Extending an urban analysis informed by drug, set, and setting

BACKGROUND

Opioid overdoses are primarily discussed by the pharmacological properties of the drugs used. Research shows that other factors such as the social/physical environment and the mental/emotional states can have an impact on overdose events. Ataiants and colleagues (2020) used Zinberg's "drug, set, and setting" framework to identify circumstances surrounding overdose experiences of street-involved women in Philadelphia. The aim of this paper is to extend their analysis to a diverse sample of suburban women who experienced overdoses.

METHODS

The mixed-methods design consisted of ethnographic fieldwork, in-depth interviews, and brief surveys with 32 suburban women who use opioids. Inductive theoretical reasoning and constant comparative analysis facilitated themes emerging within the "drug, set, and setting" framework.

RESULTS

Eighteen out of 32 women identified "drug" as the primary factor involved in their overdose events. Major themes were an inability to identify the synthetic opioid fentanyl, lack of knowledge or control over how much to use, poly-substance use, and an insufficient understanding of risks. Eleven out of 32 women linked "set" to their overdose experiences. Themes included emotional trauma, such as death of a child, child custody issues, and mental health conditions, such as depression. Six out of 32 women associated "setting" with one of their overdose experiences. Themes were related to being with friends or partners that used, and having recently been released from treatment or incarceration.

CONCLUSION

Findings show similar themes found among an urban sample, adding insight on the need for effective overdose interventions targeted for suburban populations. The opioid crisis is not confined to the cities, and neither should services aimed at addressing opioid overdose. The knowledge provided here can help policy makers support female-centered harm reduction services not only in urban areas but also in the suburbs.

Layperson reversal of opioid overdose supported by smartphone alert: A prospective observational cohort study

BACKGROUND

Rapid naloxone administration is crucial in reversing an opioid overdose. We investigated whether equipping community members, including people who use opioids (PWUO), with a smartphone application enabling them to signal and respond to suspected overdose would support naloxone administration in advance of Emrgency Medical Services (EMS).

METHODS

This observational cohort study of opioid overdose intervention used a dedicated smartphone app, UnityPhilly, activated by volunteers witnessing an overdose to signal other nearby volunteers in Philadelphia (March 2019 - February 2020). Alerted volunteers chose to respond, or declined to respond, or ignored/missed the alert. Witnessing volunteer was connected to 9-1-1 through a semi-automated telephone call. The primary outcome was layperson-initiated overdose reversal before EMS arrival, and a secondary outcome was hospital transfer. This study is registered with ClinicalTrials.gov, NCT03305497.

FINDINGS

112 volunteers, including 57 PWUO and 55 community members, signaled 291 suspected opioid overdose alerts. 89 (30⸱6%) were false alarms. For 202 true alerts, the rate of layperson initiated naloxone use was 36⸱6% (74/202 cases). Most naloxone-use cases occurred in the street (58⸱11% (43/74)) and some in home settings (22⸱98% (17/74)). The first naloxone dose was provided by a nearby volunteer responding to the alert in 29⸱73% (22/74) of cases and by the signaling volunteer in 70⸱27% (52/74) of cases. Successful reversal was reported in 95⸱9% (71/74) of cases. Layperson intervention preceded EMS by 5 min or more in 59⸱5% of cases. Recovery without hospital transport was reported in 52⸱7% (39/74) of cases.

INTERPRETATION

Our findings support the benefits of equipping community members, potentially witnessing suspected opioid overdose, with naloxone and an emergency response community smartphone app, alerting EMS and nearby laypersons to provide additional naloxone.

COVID-19, mental health, and opioid use disorder: Old and new public health crises intertwine

The United States is facing both the coronavirus disease 2019 (COVID-19) pandemic and an ongoing epidemic of opioid overdose. Opioid use disorder is associated with other mental health problems, trauma, and social and health disparities. While the United States has acted to improve access to treatment for mental health and opioid use, research will be needed to understand the effectiveness of new policies in the context of COVID-19.
