OBJECTIVES/GOALS: Illuminate processes and findings of the Environmental Scan of Adaptive Capacity and Preparedness of CTSAs done by the CTSA Working Group. Share challenges, strategies, and lessons learned for CTSAs to build Capacity to address clinical and translational barriers while responding to emergencies. METHODS/STUDY POPULATION: An Environmental Scan approach for searching, collecting, analyzing and using information from diverse sources regarding CTSA hubs experiences during emergency as related to research implementation, translation, support, adaptation, and preparedness: - Triangulating multiple data sources and mixed methods (e.g., literature review, document/RPPR analysis, and expert review); - Secondary analysis of the JCTS COVID-19 Survey of the CTSAs: challenges, lessons learned, and practices that work in various program components/areas; - Using feedback of CTSA professionals from multiple disciplines to enhance our knowledge of emergency preparedness and efficient adaptation to public health and other crises. RESULTS/ANTICIPATED RESULTS: The E-scan approach helped identify challenges, successful practices, and evidence-based strategies for building adaptive capacity and preparedness of CTSAs across various scientific sectors of the translational science spectrum. Some of the findings include: - Roadmaps for the creation of new collaborative research resources (biobanks; data repositories, etc.); - Rapid clinical and research decision making during public health crises; - New community-based research strategies to facilitate communication, research dissemination, and participant recruitment based on existing trust-based networks; - Innovative resource allocation to guarantee continuity of training and research opportunities for trainees. DISCUSSION/SIGNIFICANCE: The Environmental Scan of the Adaptive Capacity of CTSA hubs provides useful knowledge and tools to diverse clinical research stakeholders for mitigating the impact of a disaster via adjusting programs, practices, and processes, and building capacity for effective, emergency-ready and responsive research, training, and community engagement.
