OBJECTIVES/GOALS: Team science is a focus of the University of Florida Clinical and Translational Science Institute (UF CTSI) Learning Health System Initiative. Citizen Scientists (CSs) are integral research partners who provide pragmatic feedback. The UF Health Cancer Center (UFHCC) aspired to adopt a similar approach to research, starting with onboarding CSs. METHODS/STUDY POPULATION: To understand the content with which they would be engaging through the CTSI, CSs first became certified through a self-paced online curriculum focused on clinical research basics. UFHCC envisioned their onboarding as a companion piece to this first course, and CSs must complete both courses to work in cancer-focused research. The new CS Cancer Curriculum consists of a mix of didactic lessons with quizzes, case studies, a behind-the-scenes look at a research lab meeting, and interviews with CSs. As with the clinical research course, the cancer course was co-developed alongside the CSs and utilized the ADDIE (Analysis, Design, Development, Implementation, Evaluation) instructional design model. The course was implemented with UF CSs from July to September 2021 through Canvas. RESULTS/ANTICIPATED RESULTS: For the nine CSs completing this pilot test, scores for all didactic quizzes across the course were mostly high. Two CSs scored a perfect 100%, three missed only one question (98%), and two CSs missed two questions (96%). A course evaluation was completed by eight of the CSs and determined that most (86%) felt that they were capable of applying what they had learned. An additional 75% felt the course empowered them to advocate for the needs of all stakeholders involved in cancer research. Qualitative responses on the evaluation found that the course helped CSs better relate to the challenges faced by other stakeholders (patients, clinicians, caregivers) and helped them conceptualize how they could contribute to cancer research. DISCUSSION/SIGNIFICANCE: The partnerships within the UF CTSI have a direct impact on patient care through research studies in Florida and nationwide. CSs can be overlooked by researchers unfamiliar with concepts of a learning health system, including those in cancer research. By engaging these stakeholders, we may soon see similar impacts to cancer-related patient care.
