OBJECTIVES/GOALS: We are using ethnographic methods and Dissemination and Implementation (D&I) frameworks to study barriers and facilitators to implementing ‘TeamMAPPS: Team Methods to Advance Processes and Performance in Science.’ TeamMAPPS is an evidence-based Team Science curriculum deployed as five online modules and being implemented across CTSA hubs. METHODS/STUDY POPULATION: For this pre-implementation study, we used the Implementation Mapping framework to understand likely barriers and facilitators, with the aim of designing implementation strategies and long-term outcome measures. Data included field notes from a two-day train-the-trainer, one visit to a key implementing site, and 27 interviews. Participants were four TeamMAPPS conceptualizers, four module designers, and 15 implementers from seven implementing sites, each with a CTSA hub (four were interviewed twice). We coded transcripts using the Consolidated Framework for Implementation Research (CFIR) to identify contextual barriers and facilitators to D&I, the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) D&I outcomes framework, and target competencies of TeamMAPPS. RESULTS/ANTICIPATED RESULTS: Priority D&I outcomes that emerged were adoption, reach, and effectiveness. Potential barriers/facilitators to “adoption” included institutional willingness to incentivize scientists to utilize TeamMAPPS, support for Team Science at CTSAs, and systems of rewards for scientists to undergo trainings. Anticipated barriers/facilitators for “reach” were closely tied to adoption, such as institutions’ ability to persuade or require scientists to take trainings. Other issues relevant to reach included the time it takes to time to complete TeamMAPPS and potentially fraught intra-team dynamics arising if modules are implemented as a whole-team intervention. Anticipated barriers/facilitators for “effectiveness” included having adequate tools to assess actual impact. DISCUSSION/SIGNIFICANCE: TeamMAPPS has the potential to accelerate advances in translational sciences across the CTSA consortium. As this D&I study proceeds we will continue Implementation Mapping and use the Expert Recommendations for Implementing Change (ERIC) to develop bundles of implementer-informed strategies to the effectively deliver TeamMAPPS among CTSAs.
