Aquifer Geriatrics, formerly web-based Geriatrics Education Modules, was initially developed through Donald W. Reynolds Foundation funding, and is now the national curriculum of the American Geriatrics Society and the Association of Directors of Geriatric Academic Programs. Aquifer Geriatrics consists of 26 evidence-based, peer-reviewed, online case-based modules based on the Association of American Medical Colleges/John A. Hartford Foundation Minimum Geriatrics Competencies for Medical Students and is available by subscription at www.aquifer.org/courses. This curriculum aims to help address the national shortage of geriatrics educators, complement current teaching, bridge content gaps in geriatrics education, and standardize geriatrics-focused educational content. This report will describe the development of Aquifer Geriatrics, highlight best practices to incorporate cases in a variety of teaching settings, describe teaching methods that utilize the curriculum to create a robust experience for learners, and address the cost of obtaining the curriculum.
