The didactic modules in this course were developed for Internal Medicine residents working on the inpatient Geriatric Consult Service at the University of Iowa Hospitals and Clinics as part of their geriatric rotation. They will be useful to all physicians, residents, and students who provide or who will provide primary care to elderly patients. Each module contains didactic information about the associated topic, and may contain one or more interactive case studies, links to GeriaSims patient care simulations, links to video presentations, or links to printable clinical tools.
