OBJECTIVES/SPECIFIC AIMS: The aim of this program is to provide early support to motivated medical students interested in a career as a physician-scientist in a framework of competency-based medical education. The CTSA creates an opportunity to provide clinical research education and protected time for research for medical students in clinical and translational research. METHODS/STUDY POPULATION: This physician-scientist experience offers research opportunities in a wide variety of research disciplines, focused on clinical and translational investigations. The program offers both five-month and one-year blocks of protected research time. The five-month option is integrated into the four- year medical curriculum. The one-year option requires enrollment in an established Master of Clinical Research degree. Both options provide research experience under the mentorship of a physician-scientist. The five-month option aligns with UME competencies categorized under the six ACGME Domains of Competence. The one-year option includes coursework in research design, biostatistics, research ethics, data management, scientific communication, and proposal development within the CTSA-based education program. All students in the program attend a bimonthly journal club and seminar series starting in year one and extending through the research experience. This includes discussion of the importance of mentorship, selecting a residency, scientific writing and presentation, and personal narratives of physician-scientists and their pathways to this career. All students will be followed to determine career outcome. RESULTS/ANTICIPATED RESULTS: Between 2015 and 2018, 67 students entered the program 46% selected the year out, and 56% selected the 5-month option. Students selecting this program constitute about 10% of the medical student population overall. We have had 17 graduates of the program to date. 55% of the cohort is women which parallels the OHSU medical student population. Long-term follow-up of at least 10 years will be needed to determine career outcomes. We assess student productivity by traditional measures of submitted abstracts, manuscripts, and presentations as well as longer term outcomes such as career orientation in medicine such as entry into a research-oriented residency and ultimately into an academic medicine or research. DISCUSSION/SIGNIFICANCE OF IMPACT: The OHSU physician-scientist experience successfully matches medical students with a diverse set of research mentors focused on the CTSA. Although institutional structures determine the variety of specific research opportunities, the integration of physician-scientist training into a CTSA-based training program expands the reach of training programs such as the TL1.
