Thank you very much for the opportunity to appear before the standing committee. It's a particular honour for me because I have a long-standing connection to Canada ever since I spent a high school year in Alberta in the early 1990s.
As an active clinician and researcher, I specialize in opioid and cocaine use and dependence, as well as the treatment of concurrent psychiatric disorders. I currently serve as head physician of the addiction department at the University of Basel Psychiatric Clinics.
Our department provides opioid-assisted treatment to approximately 500 patients. In addition, we offer in-patient treatment, as well as outreach treatment, and we provide medical services at Basel's two supervised consumption sites.
Canada is currently grappling with a severe opioid overdose crisis that is devastating communities across the country. In 2015, I had the opportunity to spend several months as a research fellow at the University of British Columbia, and I was struck by how deeply the opioid crisis is affecting individuals and society as a whole.
Switzerland, too, faced a public health crisis related to opioids in the 1980s and 1990s. Intravenous heroin use was the key driver of the HIV epidemic, which hit Switzerland harder than any other European country. Open drug scenes were visible in all major Swiss cities, and per-capita overdose deaths reached the highest levels in the world.
Switzerland's political system is based on compromise between linguistic regions, urban and rural areas and political parties across the spectrum that have to share governmental responsibilities. Laws are often subject to political referendums. Overall, our political decision-making processes are slow.
However, in the early 1990s, the urgency of the situation was so great that politicians, law enforcement, the treatment system and individuals who use drugs, along with their families, came together to completely overhaul Switzerland's drug policy. The result was the introduction of harm reduction as a fourth pillar of Swiss drug policy alongside prevention, therapy and law enforcement. Harm reduction measures, such as supervised consumption services, needle and syringe dispensing, and low-threshold social initiatives like supported housing, employment and free meals, were implemented on a broad scale. Importantly, this was accompanied by the introduction of patient-centred, low-threshold treatment for opioid dependence. Opioid agonist therapy with methadone became easily accessible, covered by mandatory health insurance and available nationwide, primarily in general practitioners' offices but also in specialized institutions like ours.
Patients have always been involved in decisions regarding their treatment, and most unnecessary regulations and restrictions were abolished. For the majority of patients, take-home methadone was introduced. Despite these measures, it became clear that a portion of the opioid-dependent patients still did not benefit from treatment. This is why Switzerland introduced heroin-assisted treatment in 1994, providing pharmaceutical heroin under medical supervision, embedded in a therapeutic environment that includes addiction and psychiatric care, as well as social support. Heroin is prescribed for injection, as well as in the form of tablets. Currently, we are also investigating the prescription of nasal heroin in a national multicentre study.
It's important to emphasize that heroin-assisted treatment is much more than just dispensing heroin. It's a comprehensive, interdisciplinary and cost-effective treatment approach that also addresses psychiatric comorbidities, such as psychosis, depression or trauma, which often contribute to addiction in the first place. Up to 80% of patients in opioid agonist therapy in Switzerland have such concurrent psychiatric problems. I firmly believe that opioid agonist therapy can only achieve its full potential when these co-occurring issues are also addressed.
All of these measures were implemented on a large scale and were made available across the nation. Switzerland, while smaller than Nova Scotia and with much of it mountainous, now has 16 supervised consumption services and more than 1,800 patients in 24 heroin-assisted treatment centres. Why is this important? We know that only patients receiving treatment can benefit from it. In Switzerland, around 80% of opioid-dependent people are engaged in opioid agonist therapy with a range of medications that they can choose from on any given day.
In Canada, this proportion is much lower. In our outpatient clinic in Basel alone, we treat over 200 patients with pharmaceutical heroin. If we were to translate this number to Toronto, that would imply approximately 3,000 patients in heroin-assisted treatment. However, when I prepared for this meeting, I reviewed Dr. de Villa's recent statement to the committee. She noted that the only injectable opioid agonist treatment program in Toronto has 35 patients.
The opioid-dependent population in Switzerland is now an aging cohort and new solutions are needed to care for elderly patients.
The number of new opioid users has declined steeply since the 1990s. The provision of heroin-assisted treatment has been confirmed in five popular referendums, and problematic opioid use is viewed as a medical issue, leading to a reduction in stigma around this treatment. We're convinced that this is the result of the broad introduction of harm reduction measures and low-threshold opioid agonist therapy, including injectable options and treatment of concurrent disorders.
Thank you for your attention. I'm happy to answer any questions.
