ACEP recommends that people with cellular phones add “ICE” (In Case of Emergency) entries into their cell phone address books. This stands for "In Case of Emergency." Medical professionals recognize this acronym and use it to notify the person’s emergency contacts and to obtain critical medical information if a patient arrives at an emergency department unconscious or unable to answer questions. This can give doctors and nurses vital information to provide better and more effective care.

It is recommended that people save at least two numbers and be sure that both people are familiar with their medical history. They can be saved as “ICE — 1” and “ICE — 2” or with names such as “ICE —  Mom.” In all cases, the “ICE” designation should come first.
