Environmental Geriatrics is the study and application of design principles to interiors and products to optimize the health, function, and well-being of older adults. Clinicians can serve as a valuable resource to patients and their caregivers by providing them with advice and information on how to avoid excess disability through age-appropriate design. Funded by the Donald W. Reynolds Foundation, we have developed an evidence-based 3D animated course, Environmental Geriatrics: Improving Function & Safety by Design, http://www.environmentalgeriatrics.org for medical students and primary care physicians as well as other healthcare professionals involved in the care of older patients.
