Communicating risk in the context of methadone formulation changes: A qualitative study of overdose warning posters in Vancouver, Canada

Awareness and knowledge of drug decriminalization among people who use drugs in British Columbia: a multi-method pre-implementation study

BACKGROUND

In January 2023, British Columbia implemented a three-year exemption to Controlled Drugs and Substances Act, as granted by the federal government of Canada, to decriminalize the personal possession of small amounts of certain illegal drugs. This decriminalization policy, the first in Canada, was announced in response to the overdose emergency in British Columbia as a public health intervention that could help curb overdose deaths by reducing the impact of criminalization and increasing access to health and social services through stigma reduction.

METHODS

The current multi-method study examines people who use drugs' awareness and knowledge of British Columbia's decriminalization model through cross-sectional quantitative surveys and qualitative interviews among people who use drugs from September-November 2022, immediately prior to the implementation of decriminalization.

RESULTS

Quantitative findings show that two-thirds (63%) of people who use drugs were aware of the policy, but substantial knowledge gaps existed about the legal protections afforded (threshold amount, substances included, drug trafficking, confiscation). The qualitative findings suggest that people who use drugs misunderstood the details of the provincial decriminalization model and often conflated it with regulation. Results suggest that information sharing about decriminalization were minimal pre-implementation, highlighting areas for knowledge dissemination about people who use drugs' rights under this policy.

CONCLUSIONS

Given that decriminalization in British Columbia is a new and landmark reform, and that the success of decriminalization and its benefits may be undermined by poor awareness and knowledge of it, efforts to share information, increase understanding, and empower the community, may be required to promote its implementation and benefits for the community.

Overdosevarslingssystemer – en kartleggingsoversikt med maskinlæring

Bakgrunn: Helsedirektoratet ønsker å vurdere muligheten for å etablere et nasjonalt overdosevarslingssystem (OVS) for å kunne varsle brukere om økt overdosefare. OVS som system forstås her som et sett med sammenhengende elementer som fungerer som en helhet, der hensikten er tidlig oppdagelse av økt overdoserisiko kombinert med rask varsling til de som står i fare for overdoser. Metode: Vi utførte en kartleggingsoversikt over forskning om varslingssystemer for økt overdosefare. Mål 1 var å kartlegge eksisterende forskning om effekten av et OVS (antall brukere nådd, antall overdoser, varslingshurtighet). Mål 2 var å kartlegge eksisterende forskning som kunne belyse brukeres erfaringer med slike systemer. Resultater: Vi brukte flere maskinlæringsfunksjoner for å identifisere og vurdere totalt 4102 referanser fra litteratursøk gjennomført i mars/april 2022, hvorav 11 studier oppfylte inklusjonskriteriene. Effekt av OVS på antall overdoser var ikke mulig å skille fra eksisterende overdoseforebyggende tiltak. OVS’er varslet skadereduksjonsgrupper eller erfaringskonsulenter så tidlig som fire timer etter innmeldt/oppdaget fare. Antall brukere varslet ble i stor grad ikke rapportert, antageligvis fordi data om dette ikke ble innsamlet. Fra syv kvalitative studier ble mønstre i hovedfunn sett på tvers, som omhandlet preferanser for språkbruk og innhold, hvor varslinger burde komme fra, og prinsippene bak dem. Konklusjon: Vi identifiserte lite empirisk forskning om eksisterende OVS’er, særlig relatert til effekt av slike systemer. Uten tilstrekkelig forskningsgrunnlag om effekt må vi være forsiktige med å trekke konklusjoner om hvilke typer OVS’er som bør og ikke bør innføres i Norge. Opprettelse av et OVS trenger ikke nødvendigvis innebære etablering av en ny infrastruktur, men heller være snakk om at to godt utviklede, eksisterende systemer – systemer for overvåking og skadereduksjonstiltak – kan kobles sammen.

Co-designing drug alerts for health and community workers for an emerging early warning system in Victoria, Australia

BACKGROUND

Alerts about changes in unregulated drug markets may be useful for supporting health and community workers to anticipate, prevent, and respond to unexpected adverse drug events. This study aimed to establish factors influencing the successful design and implementation of drug alerts for use in clinical and community service settings in Victoria, Australia.

METHODS

An iterative mixed methods design was used to co-produce drug alert prototypes with practitioners and managers working across various alcohol and other drug services and emergency medicine settings. A quantitative needs-analysis survey (n = 184) informed five qualitative co-design workshops (n = 31). Alert prototypes were drafted based on findings and tested for utility and acceptability. Applicable constructs from the Consolidated Framework for Implementation Research helped to conceptualise factors that impact successful alert system design.

RESULTS

Timely and reliable alerts about unexpected drug market changes were important to nearly all workers (98%) yet many reported insufficient access to this kind of information (64%). Workers considered themselves 'conduits' for information-sharing and valued alerts for increasing exposure to drug market intelligence; facilitating communication about potential threats and trends; and improving capacity for effective responding to drug-related harm. Alerts should be 'shareable' across a range of clinical and community settings and audiences. To maximise engagement and impact, alerts must command attention, be easily recognisable, be available on multiple platforms (electronic and printable formats) in varying levels of detail, and be disseminated via appropriate notification mechanisms to meet the needs of diverse stakeholder groups. Three drug alert prototypes (SMS prompt, summary flyer, and a detailed poster) were endorsed by workers as useful for supporting their work responding to unexpected drug-related harms.

DISCUSSION

Alerts informed by coordinated early warning networks that offer close to real-time detection of unexpected substances can provide rapid, evidence-based drug market intelligence to inform preventive and responsive action to drug-related harm. The success of alert systems requires adequate planning and resourcing to support design, implementation, and evaluation, which includes consultation with all relevant audiences to understand how to maximise engagement with information, recommendations, and advice. Our findings about factors impacting successful alert design have utility to inform the development of local early warning systems.

'We don't live in a harm reduction world, we live in a prohibition world': tensions arising in the design of drug alerts

BACKGROUND

Drug alerts designed for health and community workforces have potential to avert acute harms associated with unpredictable illicit drug markets, by preparing workers to respond to unusual drug-related events, and distribute information to service users. However, the design of such alerts is complicated by diverse needs of individuals, and broader socio-political contexts. Here, we discuss the tensions that arose in the process of co-designing drug alert templates with health and community workers.

METHODS

We conducted five in-depth digital co-design workshops with 31 workers employed in alcohol and other drug and urgent care settings. Our approach to analysis was informed by Iterative Categorisation and reflexive thematic analysis methods.

RESULTS

We identified five key tensions. First, there is a need to provide comprehensive information to meet the information needs of a diverse group of workers with varying knowledge levels, while also designing alerts to be clear, concise, and relevant to the work of individuals. Second, it is important that alerts do not create 'information overload'; however, it is also important that information should be available to those who want it. Third, alert design and dissemination must be perceived to be credible, to avoid 'alert scepticism'; however, credibility is challenging to develop in a broader context of criminalisation, stigmatisation, and sensationalism. Fourth, alerts must be carefully designed to achieve 'intended effects' and avoid unintended effects, while acknowledging that it is impossible to control all potential effects. Finally, while alerts may be intended for an audience of health and community workers, people who use drugs are the end-users and must be kept front of mind in the design process.

CONCLUSIONS

The co-design process revealed complexities in designing drug alerts, particularly in the context of stigmatised illicit drug use, workforce diversity, and dissemination strategies. This study has highlighted the value of developing these important risk communication tools with their target audiences to ensure that they are relevant, useful, and impactful. The findings have informed the development of our drug alert prototypes and provide local context to complement existing best-practice risk-communications literature.

Awareness and knowledge of the Good Samaritan Drug Overdose Act among people at risk of witnessing an overdose in British Columbia, Canada: a multi-methods cross sectional study

Introduction

Bystanders to drug overdoses often avoid or delay calling 9–1-1 and cite fear of police involvement as a main reason. In 2017, the Good Samaritan Drug Overdose Act (GSDOA) was enacted by the Canadian government to provide people present at an overdose with legal protection from charges for simple drug possession, and conditions stemming from simple possession. Few studies have taken a multi-methods approach to evaluating the GSDOA. We used quantitative surveys and qualitative interviews to explore awareness, understanding, and perceptions of the GSDOA in people at risk of witnessing an overdose.

Methods

Quantitative cross-sectional surveys and qualitative telephone interviews were conducted with adults and youth at risk of witnessing an overdose across British Columbia. Cross-sectional survey participants were recruited at 19 Take Home Naloxone sites and online through Foundry. Multivariable logistic regression models were constructed hierarchically to determine factors associated with GSDOA awareness. Telephone interview participants were recruited by research assistants with lived/living experience of substance use. Deductive and inductive thematic analyses were conducted to identify major themes.

Results

Overall, 52.7% (n = 296) of the quantitative study sample (N = 453) reported being aware of the GSDOA. In multivariable analysis, cellphone possession (adjusted odds ratio [AOR] = 2.19; 95% confidence interval [CI] 1.36, 3.54) and having recently witnessed an opioid overdose (AOR = 2.34; 95% CI 1.45, 3.80) were positively associated with GSDOA awareness. Young adults (25 – 34 years) were more likely to be aware of the Act (AOR = 2.10; 95% CI 1.11, 3.98) compared to youth (16–24 years). Qualitative interviews (N = 42) revealed that many overestimated the protections offered by the GSDOA. To increase awareness and knowledge of the Act among youth, participants recommended adding the GSDOA to school curricula and using social media. Word of mouth was suggested to reach adults.

Conclusion

Both awareness and knowledge of the GSDOA remain low in BC, with many overestimating the protections the Act offers. Dissemination efforts should be led by people with lived/living experience and should target those with limited awareness and understanding of the Act as misunderstandings can erode trust in law enforcement and harm reduction policy.

Action-focused, plain language communication for overdose prevention: A qualitative analysis of Rhode Island's overdose surveillance and information dashboard

BACKGROUND

In 2015, the state of Rhode Island reported the fifth highest drug overdose mortality rate in the United States. In response to this crisis, Rhode Island created a statewide, publicly accessible drug surveillance and information system, www.PreventOverdoseRI.org (PORI). Alongside near real-time overdose surveillance data, PORI provides plain language materials and resources regarding overdose prevention, recognition and response. We sought to determine how people who use drugs (PWUD) perceive and utilize overdose prevention material, and to evaluate PORI's action-based, plain language content.

METHODS

We conducted 21 semi-structured qualitative interviews with PWUD from February-June 2017 in the state of Rhode Island. Data were audio-recorded, transcribed, coded in NVivo (Version 11), and key themes were developed.

RESULTS

Participants viewed online health promotion and harm reduction materials as a useful approach for overdose prevention. Information displayed as accessible, action-driven statements was seen as most desirable for learning and dissemination. After viewing overdose prevention material, participants reported feeling better prepared for responding to an accidental overdose and motivated to share the infographics and website to other people either at risk for or likely to witness an overdose.

CONCLUSION

Action-focused, plain language approaches for overdose prevention materials can be of particular use for public health campaigns addressing opioid overdose crises. Overdose prevention health campaigns should incorporate evidence-based testing to ensure that outreach material is grounded in plain language techniques.

A pragmatic harm reduction approach to manage a large outbreak of wound botulism in people who inject drugs, Scotland 2015

Background

People who inject drugs (PWID) are at an increased risk of wound botulism, a potentially fatal acute paralytic illness. During the first 6 months of 2015, a large outbreak of wound botulism was confirmed among PWID in Scotland, which resulted in the largest outbreak in Europe to date.

Methods

A multidisciplinary Incident Management Team (IMT) was convened to conduct an outbreak investigation, which consisted of enhanced surveillance of cases in order to characterise risk factors and identify potential sources of infection.

Results

Between the 24th of December 2014 and the 30th of May 2015, a total of 40 cases were reported across six regions in Scotland. The majority of the cases were male, over 30 and residents in Glasgow. All epidemiological evidence suggested a contaminated batch of heroin or cutting agent as the source of the outbreak. There are significant challenges associated with managing an outbreak among PWID, given their vulnerability and complex addiction needs. Thus, a pragmatic harm reduction approach was adopted which focused on reducing the risk of infection for those who continued to inject and limited consequences for those who got infected.

Conclusions

The management of this outbreak highlighted the importance and need for pragmatic harm reduction interventions which support the addiction needs of PWID during an outbreak of spore-forming bacteria. Given the scale of this outbreak, the experimental learning gained during this and similar outbreaks involving spore-forming bacteria in the UK was collated into national guidance to improve the management and investigation of future outbreaks among PWID.

Prevalence of Heavy Alcohol Use Among People Receiving Methadone Following Change to Methadose

BACKGROUND

A recent switch in methadone formulation from methadone (1 mg/mL) to Methadose (10 mg/mL) in British Columbia (BC), Canada, was associated with increased reports of opioid withdrawal and increases in illicit opioid use. Impacts on other forms of drug use have not been assessed. Since alcohol use is common among people receiving Medication-Assisted Treatment (MAT), we assessed if switch was associated with increased prevalence of heavy alcohol use.

METHODS

Drawing on data from two open prospective cohort studies of people who inject drugs in Vancouver, BC, generalized estimating equations (GEE) model examined relationship between methadone formulation change and heavy alcohol use, defined by National Institute for Alcohol Abuse and Alcoholism (NIAAA). A sub-analysis examined relationship with heavier drinking defined as at least eight drinks per day on average in last six months.

RESULTS

Between June 2013 and May 2015, a total of 787 participants on methadone were eligible for the present analysis, of which 123 (15.6%) reported heavy drinking at least once in last six months. In an unadjusted GEE model, Methadose use was not significantly associated with an increased likelihood of heavy drinking [Odds Ratio (OR) = 1.03; 95% Confidence interval (CI) = 0.87-1.21]. Methadose use was not significantly associated with an increased likelihood of drinking at least eight drinks daily on average (OR = 1.09, 95% CI = 0.72-1.65).

CONCLUSIONS

Despite reported changes in opioid use patterns coinciding with the change, there appeared to be no effect of the methadone formulation change on heavy drinking in this setting.
