ARCH Patient Outcomes Evaluation

This study evaluates the ARCH team model for its potential to meet the needs of socially marginalized patients who use substances.

 

Patients eligible for recruitment to this study were those with: 

i) unstable housing,
ii) no stable income, and/or
iii) active substance use.

Patients were recruited by the ARCH team at the RAH site, and a comparison group was recruited from two clinical sites in Calgary (the Peter Lougheed Centre and the Sheldon Chumir Centre). Study participants agreed to provide baseline and follow-up survey data, as well as consenting to allow access to their health and social service records. Altogether, participant data has been collected for an 18 month study period, including 6 months prior to and 12 months following baseline.

Our primary outcome of interest is the impact of the ARCH intervention on Emergency Department use; secondary outcomes include primary care attachment, substance use, housing, and unmet needs for care. This study is complemented by an economic evaluation and a qualitative process evaluation.
