Abstract
OBJECTIVE: System planners and funders encounter many challenges in taking action toward evidence-informed enhancement of substance use treatment systems. Researchers are increasingly asked to contribute expertise to these processes through comprehensive system reviews. In this role, all parties can benefit from guiding frameworks to help organize key questions and data collection activities, and thereby set the stage for both high-level and on-the-ground strategic directions and recommendations. This article summarizes seven core principles of substance use treatment system design that are supported by a large international evidence base and that together have proven applicable as a framework for several systems review projects conducted predominantly in Canada. METHOD: The methodology was based on a narrative review approach. RESULTS: The principles address a wide range of issues. Specifically, a broad systems approach is needed to address the full spectrum of issues; accessibility and effectiveness are improved through collaboration across stakeholders; a range of system supports are needed; need for services should be grounded in self-determination, holistic cultural practices, choice, and partnership; attention to diversity and social-structural disadvantages are crucial to equitable system design; systematic screening and assessment is needed to match people to appropriate treatment services in a stepped service framework; and, last, individualized treatment planning must include the right mix of evidence-informed interventions. CONCLUSIONS: By bringing researchers and stakeholders back to the high-level goals of substance use treatment systems, these principles provide a comprehensive, evidence-based, organizing framework that has the potential to improve the quality of system design and review internationally.
