My Health Passports are forms that contain information about an individual's health history, medications, communication preferences, and other needs that can be filled out by individuals with Down syndrome and their families. These documents can quickly inform healthcare providers who may be unfamiliar with the individual with Down syndrome (e.g. a doctor at a hospital or urgent care clinic).
A general example can be found at this link. It was developed by the University of South Florida and Florida Center for Inclusive Communities.
State-specific examples can be found on the website of the Stony Brook University linked here.
