Insights
The Prevention and Early Intervention for Psychosis Program (PEPP)-Montreal offers rapid access to care for psychosis. This model successfully reduces treatment delays and can be adapted for other mental health services.
Area of Science:
- Psychiatry
- Mental Health Services Research
Background:
- Early intervention is crucial for psychosis treatment outcomes.
- Reducing delays in accessing care is a key objective for early intervention programs.
- Existing models may face challenges in providing timely and high-quality services.
Purpose of the Study:
- To describe the entry protocol of the PEPP-Montreal program.
- To demonstrate how this protocol reduces delays in accessing psychosis care.
- To provide a model for other services aiming to shorten treatment initiation times.
Main Methods:
- Implemented a single intake clinician model for streamlined access.
- Ensured prompt response and sensitive handling of all referrals.
- Guaranteed initial assessments within 72 hours.
- Maintained strong referral source relationships and conducted outreach.
Main Results:
- Successfully responded to 1750 referrals within 72 hours since 2003.
- Achieved high family involvement (60%) in the intake process.
- Potentially averted hospitalization in over half of emergency room referrals.
- Demonstrated low staff turnover, indicating program sustainability.
Conclusions:
- The PEPP-Montreal protocol provides rapid, engaging, and youth-friendly access to high-quality psychosis care.
- The model's success in reducing treatment delays makes it adaptable for other early intervention services.
- This protocol can serve as a benchmark for improving access in psychosis and other mental health services.
Aim:
This paper aims to describe the entry protocol of the Prevention and Early Intervention for Psychosis Program (PEPP)-Montreal, an early intervention program for psychosis. The protocol is designed to fulfil a key objective of the early intervention movement-reducing delays to accessing high-quality care. The paper also aims to describe how this rapid entry protocol can be deployed in other services interested in reducing delays in initiating treatment.
Methods:
PEPP provides rapid, easy access to quality care by placing a single, well-trained professional, the intake clinician, at the point of entry. Anyone can refer a youth directly and without formalities to the intake clinician who responds promptly and sensitively to all help-seeking, whether by a youth, a family member, a school counsellor or anyone acting on behalf of a youth in need. To promote accessibility, PEPP guarantees an initial assessment within 72 hours; maintains relationships with referral sources; and conducts awareness-enhancing outreach activities.
Results:
Since 2003, PEPP has received 1750 referrals, which have all been responded to within 72 hours. Families have been involved in the intake process in 60% of the cases and hospitalization may have been averted in over half of the referrals originating from emergency-room services. Another indicator of success is the very low turnover in the intake clinician's position. Overall, the PEPP model has succeeded in providing rapid, engaging, easy and youth-friendly access to high-quality care.
Conclusion:
The success of this protocol at PEPP has inspired the entry protocols at other first-episode psychosis services. Its ability to provide rapid, engaging access to high-quality services may allow this protocol to become a model for other early intervention services for psychosis and other mental illnesses.
