Fostering Accessibility to Mental Health Services for Youth Experiencing Homelessness in Montreal, Canada: A Historical Cohort Comparison Study

BACKGROUND: (RIPAJ) was established in Montréal in 2003 through collaboration between community and governmental health organizations. In 2016, RIPAJ joined the national Adolescent/Young Adult Connections to Community-driven Early Strengths-based Stigma-free services-Open Minds (ACCESS-OM) initiative, aiming to enhance mental healthcare accessibility for youth experiencing homelessness. AIMS: This study evaluates the impact of this integrated approach on referral trends and wait times before and during ACCESS-OM RIPAJ implementation. METHOD: Monthly referrals and wait times for first appointment were recorded for a historical cohort (2014-2015) and the ACCESS-OM RIPAJ period (2016-2020). We used Poisson and Cox regression models to analyze trends in referral rates and wait times, with 2014 as reference period. Seasonality was controlled by incorporating calendar month in the models. Additional Cox regressions examined individual-level sociodemographic and clinical factors associated with post-implementation wait times. RESULTS: We analyzed 158 referrals for 2014 to 2015 and 681 for 2016 to 2020. Monthly referrals increased significantly, peaking at 2.5 times the 2014 level. Wait times remained stable, with 73.5% evaluated within 72 hr. The hazard ratio for wait times during the peak period was 0.87 (95% CI [0.63, 1.20]) indicating no significant change despite the surge in referrals. Older age and self-referral were associated with reduced wait times. CONCLUSIONS: This collaborative model successfully increased mental healthcare utilization among youth experiencing homelessness, providing valuable insights for addressing the unmet needs of this vulnerable population and potentially reducing homelessness perpetuation.
