What kinds of health-care programs work the best to prevent opioid overdoses and deaths?

As the opioid crisis continues across Canada, preventing overdose and overdose-related deaths has become a critical health concern.

Research shows that people who survive an overdose are at high risk of dying from an overdose in the future. Which models of care are most effective in preventing repeat overdose?

To find out, we will investigate:

  1. Whether and how often people who survive an overdose receive: care for their drug use while in hospital, follow-up care from family doctors, specific therapy for opioid use with methadone and buprenorphine, and mental health care.
  2. Which features of care are working to prevent future overdoses and opioid-related deaths.
  3. Whether providing client-centered care that is integrated and delivered to people in a centralized location is effective for preventing opioid-related overdoses.

The results will provide important guidance for health-care providers, policy-makers and public-health officials as they design health care systems to improve health care and prevent deaths among people who use drugs.
