This paper provides an overview of early intervention (EI) services for psychosis in Canada. We describe a leading Canadian EI program's approach to enhancing access (via early case detection, open referral, and rapid response) and providing specialized phase-specific treatment. Learnings from this program's research/evaluation indicate that EI can significantly improve service user and family engagement. Achieving and maintaining symptom remission (particularly negative symptoms) may be important for better social and occupational functioning in first-episode psychosis (FEP). Our program demonstrates the feasibility of establishing and sustaining an open referral, rapid-response system to address the chronic systemic problems of long waiting lists and barriers to access. We argue that an integrated clinical-research program based on specialized EI guidelines can significantly improve outcomes and advance FEP research.

These results highlight the importance of achieving and maintaining remission of both negative and positive symptoms for longer periods in patients with a first episode of a psychotic disorder and the need for effective interventions to do so.

Suffering is a core experience of FEP from which a range of positive changes can follow among service users and their families and friends. It may be beneficial for mental health services to specifically strive to promote these positive changes.

In most mental illnesses, onset occurs before the age of 25 and the earliest stages are critical. The youth bear a large share of the burden of disease associated with mental illnesses. Yet, Canadian youths with mental health difficulties face delayed detection; long waiting lists; inaccessible, unengaging services; abrupt transitions between services; and, especially in remoter regions, even a complete lack of services. Responding to this crisis, the Canadian Institutes of Health Research announced a 5-year grant that was awarded to ACCESS, a pan-Canadian network of youths, families, clinicians, researchers, policymakers, community organisations and Indigenous communities. Using strategies developed collaboratively by all stakeholders, ACCESS will execute a youth mental healthcare transformation via early detection, rapid access and appropriate, high-quality care. The project includes an innovative, mixed-methods service research component. Similar in many respects to other national youth mental health initiatives, ACCESS also exhibits important differences of scale, scope and approach.
