Beyond training providers prior to the roll-out of coordinated specialty care (CSC) for first-episode psychosis in clinical settings, implementation support for data-informed care remains an area that has received very little attention. The current paper describes the development and refinement of implementation support for the data-driven components of care in the New Journeys network, Washington State's CSC model for psychosis, comprised of 14 CSC programs. Using the Evidence-Based System for Innovation Support Logic Model, this paper outlines the individual components for implementation support, tools, training, technical assistance, and quality improvement/evaluation that have been developed for the New Journeys network. We present examples of modifications that have occurred over nine years to address the needs of clients, providers, and state-level network administrators to facilitate the data-driven components of care. We conclude with recommendations based on lessons learned in Washington State aimed at improving implementation of data-driven care in CSC models throughout the USA.
