Impact de l’ajout d’une équipe de proximité intensive pour jeunes itinérants souffrant de psychose et de toxicomanie à une clinique d’intervention précoce pour la psychose
In Canada, every night, about 6000 youths are homeless. Those suffering from psychosis and substance use disorder (SUD) are at higher risk for homelessness. Today’s literature suggests the need for dedicated interventions for this population. In 2012, an intensive outreach team (ÉQIIP SOL (ES)) was created at the CHUM, to help homeless youth suffering from psychosis and SUD (HYPS). Objective: Explore the impact of ES added to an early intervention for psychosis clinic (EIC) on service use and the symptomatic and functional outcome for the HYPS. Method: Longitudinal study comparing the outcome of HYPS who received care from ES in addition to an early intervention for psychosis clinic (EIPC) (2012-2015) to an HYPS historical cohort who received care from EIPC only (2005-2011). Housing stability (main outcome), living arrangement autonomy, global assessment of functioning scale (SOFAS), clinical global assessment scales (GAF, CGI), SUD severity (AUS, DUS) and services use (Emergency consultations and hospitalizations) have been collected prospectively for 24 months. Results: With ES + EPIC, there is a higher rate of HYPS in stable housing than with EIPC only (RR=2,38, p=0,017). Symptomatic and functional outcomes as well as drug and alcohol misuse are somewhat similar for the 2 groups. Conclusion: The addition of ES to an EIPC seems to benefit HYPS in increasing housing stability. However, poor prognostic factors of HYPS and the high intensity of the comparator treatment (EPIC) may explain why ES does not seem to have an additional impact on shortterm symptomatic, functional and SUD outcome.
