The authors describe a pilot that will include development of a Coaching Extender Platform (CEP), an asynchronous communication approach that does not require live or synchronous communication between the coach and the site. CEP’s objective is to provide an affordable way to extend the coaching function and increase coaching effectiveness. The pilot has two study aims: 1) Design and develop the CEP prototype using user-based needs assessment and user-centered design strategies and Web application development best practices and 2) Conduct a six-month pilot with four jail settings to assess CEP’s ability to increase targeted MOUD use and to understand the factors that promote and impede CEP implementation.
