The Evidence-Based Practice Navigator Tool was developed by the Research Adoption Support Center in collaboration with the Center for Implementation and The Adjacent Possible to design a practical, user-friendly tool to assist in planning the implementation of evidence-based interventions for substance use disorders and chronic pain. Editorial review of content was done by the communications firm Burness, and the tool was built by web developers at Slonky. The tool is designed for use by effectiveness researchers, healthcare system leaders and administrators, training and technical assistance provider organizations, and people tasked with implementing interventions, to identify barriers and facilitators, implementation strategies, and potential outcomes when delivering these interventions. The design and functionality of the tool were developed through user interviews with key audience members and written content for the tool was developed through collaboration with addiction medicine physicians, public health researchers, psychologists, and implementation scientists.
