The Blue Button allows you to download your personal health information, including information like your emergency contact information, health history, important test results, medications, allergies and other health information and share that information with other doctors, hospitals or caregivers that may need to know. Because you can log-in to access this information from your mobile device or a computer, it can travel with you which can make a big difference in the event of a medical emergency. Having your list of medications, allergies (especially to drugs), your key medical history and emergency contact information can save your life. When seeing other doctors, having this information helps you avoid having duplicate procedures and tests, saving time and money. And, as more health care providers sign on to offer Blue Button, they will be able to share information to ensure that you are getting the most coordinated care possible—so all the health care providers you are seeing are on the same page.
