Specific Aim 3: Using the national experts gathered together under the umbrella of the Center for Health Equity Research and Promotions (CHERP) Implementation Research Collaborative, develop a set of guidelines outlining best FE practices in VA implementation research. Relevance to the VA, Anticipated Results, and Future Directions: This Short Term Project is designed to provide rapid results for developing the best approach toward the use of FE in VA implementation science. As such this proposal is responsive to the VA Health Services Research & Development (HSR&D) priority topics for both implementation and management and research methodology. The systematic review, the qualitative report, and the FE guidelines that will emerge from the project will have wide-spread applications within the VA implementation community, thereby supporting the HSR&D research mission. The study will also serve as needed pilot data for a future Merit Review award application designed to provide the theoretical and practical approaches toward FE use within the VA.
