ARCH Patient Outcomes Evaluation

This study examines whether exposure to enhanced multidisciplinary care for an inner-city population leads to improved health care resource use, social stability, and health status compared to usual care.  

 

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.

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 provided baseline and follow-up survey data, and allowed 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.

The future results of this study have the potential to inform the systematic development and implementation of acute care interventions in meeting the needs of inner-city patients who use drugs and/or experience social instability.
