Costs - The investigators will measure the cost of both implementation strategies both prospectively and retrospectively. The investigators will collect data on implementation activities during both the standard VA and enhanced implementation strategies. These costs and activities will be assessed for the investigators' operational partners, local champions, and external facilitators, as well as personnel from the implementation sites at the VISN, VAMC, and CBOCs. The investigators will first examine the components of each implementation strategy and then identify activities for each component. These activities will include clinical workflow mapping, development of training materials, training sessions, meetings, and conference calls. The investigators will develop project logs to document these activities and time spent on each activity. The external facilitators, local champions and frontline providers on the implementation team will record the logs on a regular basis. The investigators will review meeting and conference call minutes to document time spent and attendance by the facilitation team, operational partners and clinical leaders and frontline providers. TOP intervention costs will be assessed from CDW (using provider IDs to identify TOP encounters).
