Evaluating a transitional housing program for people who use substances (PWUS) who experience homelessness and live with a mental health issue: a mixed-methods study protocol in Sudbury Ontario.

BACKGROUND

A new transitional housing program was established in Sudbury, Ontario, Canada, in response to the escalating global prevalence of substance use and homelessness, and the specific challenges faced in Northern Ontario. This protocol outlines a comprehensive program evaluation to assess its impact on patient outcomes, healthcare utilization, and client perspectives.

METHODS

We will conduct a parallel mixed-method study that includes the analysis of single-center-level administrative health data and primary data collection. This includes a longitudinal observational study (target n = 1,200), pre- and post-admission quantitative interviews (target n = 40), and qualitative interviews (target n = 40). We will implement a participatory approach to this evaluation collaborating with people who use substances, frontline staff, and decision-makers. Data analysis methods include a range of statistical techniques, including logistic regression models, Cox proportional hazards models, Kaplan-Meier curves, Generalized Estimating Equations, and thematic qualitative analysis, ensuring a robust evaluation of patient outcomes and healthcare utilization.

DISCUSSION

This protocol underpins a comprehensive assessment aimed at providing insights into the program's effectiveness in addressing substance use-related challenges, reducing healthcare disparities, and improving patient outcomes, such as stable housing and increased social capital. All study procedures adhere to the ethical principles outlined in the Tri-Council Policy Statement: Ethical Conduct for Research Involving Humans. Findings will be disseminated progressively through established committees and working groups and subsequently published in peer-reviewed journals. Anticipated outcomes include informing evidence-based healthcare decision-making and driving improvements in addiction treatment practices within healthcare settings.
