Enhanced Opioid Supply Programs Yield Positive Health Outcomes

Wed 23rd Apr, 2025

Recent research conducted by ICES and Unity Health Toronto has demonstrated that safer opioid supply (SOS) initiatives, along with methadone treatment, significantly reduce the incidence of opioid overdoses, healthcare utilization, and overall costs associated with opioid use disorder.

The findings, published in The Lancet Public Health, indicate that SOS programs provide pharmaceutical-grade opioids, such as hydromorphone, to individuals facing challenges with opioid use disorder. These prescribed opioids offer a safer alternative compared to the unpredictable and potent substances available in the unregulated market.

According to the study, which is the first of its kind to assess the effects of SOS programs against opioid agonist treatment (OAT), researchers analyzed health outcomes for individuals newly prescribed SOS and those beginning methadone treatment from 2016 to 2021. The follow-up period extended through the end of 2022.

The analysis included 991 individuals newly prescribed SOS and 26,116 new OAT (methadone) users. Notably, patients receiving SOS had more complex medical backgrounds, including higher rates of HIV, hepatitis C, earlier opioid overdoses, and infections, indicating that this group generally presented with greater medical challenges upon commencing treatment.

After matching 856 new SOS patients with a similar number of methadone recipients based on health conditions, demographics, and geographical location, the study revealed that both groups experienced considerable reductions in opioid overdoses, emergency department visits, hospitalizations, the emergence of new infections, and overall healthcare costs in the following year. Additionally, rates of death related to opioids or other causes remained low in both groups.

While both treatment options showed effectiveness in lowering the risk of overdose and improving health outcomes, individuals starting on methadone exhibited a marginally lower risk of overdose and hospital admission compared to those on the SOS program. However, it was noted that methadone patients were more likely to discontinue treatment. Once the higher dropout rate in the methadone cohort was considered, the majority of the advantages associated with methadone over SOS were diminished, except for slightly lower toxicity levels observed in methadone recipients.

The findings suggest that neither treatment option serves as a universal solution; however, both are effective in mitigating overdose risks and enhancing health outcomes. The study emphasizes the complementary nature of SOS and methadone treatments, highlighting that for individuals who have struggled with conventional therapies, SOS programs can provide essential support. Implementing SOS programs has been associated with a decrease in hospital visits, infections, and overdose incidents.

Researchers propose that the distinct patterns of unregulated drug use among the two groups, along with the higher severity of opioid use disorder in SOS patients, may explain the comparatively lower risk of overdose in methadone recipients.

These results underscore the importance of integrating safer supply initiatives alongside opioid agonist treatments in comprehensive strategies aimed at assisting individuals at risk of overdose in Ontario. Such programs are particularly beneficial for those facing significant medical complexities and a history of severe harm from substance use.
