The project will compare the standard VA implementation strategy to the enhanced implementation strategy. All VAMCs will receive the enhanced implementation strategy if they need it, but the time period during which they will receive the enhanced implementation strategy will be randomized. This will allow us to determine whether more patients are reached by the TOP intervention during standard implementation compared to enhanced implementation. This design will also allow us to document improvements in perceived access and PTSD outcomes for patients at sites that successfully implement the TOP intervention. Data will be collected from patient survey and chart review for all patients sampled for the evaluation. Participating patients will complete a baseline survey and 3 follow-up surveys. The reach implementation outcome measure will be specified as the proportion of sampled patients who received the TOP intervention. PTSD outcomes will be specified as a continuous change in patient self-reported symptom severity between baseline and follow-up. Perceived access will be measured using items specifically developed for the project. Provider adoption will be assessed with qualitative interviews of all CBOC clinicians treating a sampled patient as well as members of the TOP intervention team. 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.
