Children with chronic medical conditions rely on complex management plans for problems that cause them to be at increased risk for suboptimal outcomes in emergency situations. The emergency information form (EIF) is a medical summary that provides rapid access to critical information to physicians and other members of the health care team so that optimal emergency medical care can be provided. This statement describes an updated approach to EIFs and the information they contain. Essential common data elements are reviewed, integration with electronic health records is discussed, and broadening the rapid availability and use of health data for all children and youth is proposed. A broader approach to data accessibility and use could extend the benefits of rapid access to critical information for all children receiving emergency care as well as further facilitating emergency preparedness during disaster management.
