Meta:Phi LogoMentoring, Education, and Clinical Tools for Addiction: Primary Care–Hospital Integration (META:PHI) is a collaborative project to create new care pathways for addiction. Originally funded by ARTIC and implemented in seven sites in Ontario, META:PHI is now being rolled out in Toronto with the support of the Toronto Central LHIN.


The purpose of META:PHI is to integrate addiction care provided by the emergency department, hospital units, addiction medicine specialists, family doctors, and community programs, allowing patients to move smoothly between these services. Clinical education, tools, and ongoing support are provided to health care professionals working in these settings to ensure that patients are receiving the best possible care.

Meta:Phi Flow

In the META:PHI model, patients presenting to any health care setting (emergency department, hospital, primary care) with an alcohol- or opioid-related condition receive highly effective, evidence-based treatment, and upon discharge are referred to a rapid access addiction medicine (RAAM) clinic, which they can attend without a booked appointment or formal referral note. RAAM clinics also accept self-referrals, as well as referrals from withdrawal management, community services, and the criminal justice system.

At the RAAM clinic, an addiction physician immediately provides counselling, prescribes appropriate addiction medications (such as buprenorphine, naltrexone, or acamprosate), and connects patients to community treatment programs. Once patients are stabilized, they are referred back to primary care for long-term follow-up; the addiction physician provides ongoing support by being available to family physicians for re-assessments, consultations, and advice about addiction care. In this model, addiction specialists, hospital staff, family doctors, and community service agents work together to provide seamless and accessible care to patients with substance use disorders.

The result is a fully integrated system in which patients receive evidence-based care at every step. 

With the support of the Adopting Research to Improve Care program (a joint initiative of CAHO and HQO), the META:PHI care pathway has been successfully rolled out in London, Newmarket, Ottawa, Owen Sound, Sarnia, St. Catharines, and Sudbury. Currently, the META:PHI team is working with the Toronto Central Local Health Integration Network to spread the care pathway throughout Toronto.
