Purpose of the study: The Alpert Medical School of Brown University began to integrate geriatrics content into all preclerkship courses and key clerkship cases as part of a major medical school curriculum redesign in 2006. This study evaluates students' responses to geriatrics integration within the curriculum using journals kept by volunteer preclerkship and clerkship students between 2007 and 2010. The journals were used to assess the quality of curricular integration of geriatrics didactic and clinical content, to gather information for shaping the evolving curriculum, and to elicit students' responses about their professional development and caring for older adults. Design and Methods: Student "journalers" wrote narrative reactions to and evaluations of aging-related content and exposure to older patients in response to written semistructured questions. An interdisciplinary team (including a health services researcher, gerontologist, medical anthropologist, and 2 geriatricians) used qualitative analysis to code the 405 journal entries. Results: The team identified 10 themes within the following domains: (a) evaluation of efforts to integrate geriatrics within the medical school curriculum, (b) recognition and application of geriatrics principles, (c) student attitudes and cultural experiences regarding aging and the care of older patients, and (d) personal and professional development over time. Themes emerging within these domains reflect the effectiveness of geriatrics integration within the new curriculum as well as students' professional development. Implications: Journaling provides a novel and effective method for capturing medical students' responses to curricular content in real time, allowing for midcourse corrections and identifying key components of their professional development.
