Enhanced Safer Opioid Supply Programs Lead to Better Health Outcomes for High-Risk Individuals

Recent research conducted by ICES in collaboration with Unity Health Toronto highlights the positive impact of safer opioid supply (SOS) initiatives on individuals at high risk of overdose. The study emphasizes that both SOS programs and traditional methadone treatment significantly decrease rates of opioid overdoses, reduce healthcare utilization, and lower associated costs.

Safer opioid supply programs involve providing pharmaceutical-grade opioids, such as hydromorphone, to individuals dealing with opioid use disorder (OUD). These medications serve as a safer alternative to unregulated street drugs, which are often unpredictable in potency and purity, thereby reducing the risk of overdose and other health complications.

This substantial population-based study is believed to be the first to compare SOS programs directly with opioid agonist treatments like methadone and to observe the outcomes within the first year following initiation. Among nearly 27,000 participants from Ontario between 2016 and 2021, findings revealed that individuals prescribed SOS tended to have more complex health profiles, including higher prevalences of HIV, hepatitis C, and previous overdoses, indicating that SOS often reaches more medically vulnerable populations.

Furthermore, when SOS recipients were matched with similar methadone patients, both groups experienced marked declines in overdoses, emergency department visits, hospitalizations, infections, and healthcare costs throughout the subsequent year. Importantly, deaths related to opioids or other causes remained uncommon in both cohorts.

While both treatments were effective overall, a comparative analysis indicated that methadone might slightly outperform SOS in preventing overdoses and hospital admissions. However, individuals on methadone were more prone to discontinue treatment, and after adjusting for this factor, the benefits of methadone over SOS were largely diminished, with toxicities slightly lower among methadone users.

Lead researcher Dr. Tara Gomes explains that neither approach is a universal solution but underscores that both are vital components of a comprehensive harm reduction strategy. She advocates for the inclusion of safer supply programs alongside traditional treatments, particularly for individuals with high medical complexity or those who have not succeeded with conventional options like methadone. The integration of SOS has been linked to fewer hospital visits, infections, and overdoses, demonstrating its value in supporting high-risk populations.

The study also suggests that different substance use behaviors and the severity of OUD among recipients could explain the observed differences in overdose risks. Overall, these findings reinforce the importance of offering diverse and tailored treatment options to effectively combat the overdose crisis and protect vulnerable communities.

This research was published in The Lancet Public Health and provides critical insights into expanding harm reduction services to save lives and improve health outcomes for those most in need.
