A rapid review of current engagement strategies with people who use drugs in monitoring and reporting on substance use-related harms.

BACKGROUND: The Canadian drug supply has significantly increased in toxicity over the past few years, resulting in the worsening of the overdose crisis. A key initiative implemented during this crisis has been data monitoring and reporting of substance use-related harms (SRH). This literature review aims to: (1) identify strategies used for the meaningful engagement of people who use drugs (PWUD) in local, provincial, and national SRH data system planning, reporting, and action and (2) describe data monitoring and reporting strategies and common indicators of SRH within those systems. METHODS: We searched three academic and five gray literature databases for relevant literature published between 2012 and 2022. Team members who identify as PWUD and a librarian at Public Health Ontario developed search strings collaboratively. Two reviewers screened all search results and applied the eligibility criteria. We used Microsoft Excel for data management. RESULTS: Twenty-two articles met our eligibility criteria (peer-reviewed n = 10 and gray literature reports n = 12); most used qualitative methods and focused on the Canadian context (n = 20). There were few examples of PWUD engaged as authors of reports on SRH monitoring. Among information systems involving PWUD, we found two main strategies: (1) community-based strategies (e.g., word of mouth, through drug sellers, and through satellite workers) and (2) public health-based data monitoring and communication strategies (e.g., communicating drug quality and alerts to PWUD). Substance use-related mortality, hospitalizations, and emergency department visits were the indicators most commonly used in systems of SRH reporting that engaged PWUD. CONCLUSION: This review demonstrates limited engagement of PWUD and silos of activity in existing SRH data monitoring and reporting strategies. Future work is needed to better engage PWUD in these processes in an equitable manner. Building SRH monitoring systems in partnership with PWUD may increase the potential impact of these systems to reduce harms in the community.

Assessing the impact of the slow-release oral morphine drug shortages in Ontario, Canada: A population-based time series analysis.

BACKGROUND: Slow-release oral morphine (SROM) is used to manage pain, and as opioid agonist treatment (OAT). Between 2017 and 2021 in Canada, several drug shortages occurred for Kadian© (SROM-24). The purpose of this study was to evaluate the impact of these shortages on people's ability to remain on this medication. METHODS: We conducted a retrospective population-based time series analysis of SROM-24 dispensed between January 1, 2014, and December 31, 2021, in Ontario, Canada. Using interventional autoregressive integrated moving average models (ARIMA) models, we evaluated the association between SROM-24 drug shortages and treatment discontinuation. Analyses were also stratified by the SROM-24 indication (pain or OAT). RESULTS: We identified 22,479 SROM-24 recipients, of which one-third (33.9%) were aged 65 or above and just over half (51.9%) were female. In our primary analysis of monthly SROM-24 discontinuation, we observed a significant sustained monthly increase following the shortages in November 2019 (+0.29%/month; 95% CI: 0.16%, 0.43%; p < .001) with significant sudden, temporary changes following the shortages in March 2020 (+2.00%; 95% CI: 0.95%, 3.05%; p < .001), July 2021 (+3.53%; 95% CI: 2.20%, 4.86%; p < .001), and August 2021 (+4.98%; 95% CI: 3.49%, 6.47%; p < .001). Similar results were observed in our stratified analyses, with sustained high rates of discontinuation among people accessing SROM-24 as OAT. CONCLUSIONS: The SROM-24 shortages resulted in significant treatment disruptions across all recipients. These findings have important implications for those with few treatment alternatives, including people using SROM-24 as OAT who are at risk of adverse outcomes following treatment disruptions.
