What Those Symbols Really Mean (and Why They’re Important)

What Those Symbols Really Mean (and Why They’re Important)


Each year, an estimated 2.6 million people receive “harmful” emergency medical treatment that could have been avoided if lifeguards had been provided with vital information. These figures show that there is an alarming neglect in the delivery of medical information to health professionals. Therefore, medical identification (ID) is considered a critical part of emergency preparedness, providing life-saving information and ensuring better outcomes for patients in urgent situations. But what are medical identifications, how are the symbols they contain interpreted, and who should wear them?

Understanding medical IDs

Medical IDs come in different forms, but are typically a bracelet or necklace where medical information is engraved into the jewelry. Many smartphone applications allow the storage of digital medical information that can be accessed by first responders, if necessary. There are also apps that generate quick response (QR) codes that emergency personnel can scan to access medical information. Additionally, there are wallet-style cards that can be carried in a purse that contain essential medical information. People can also choose medical tattoos that discreetly display essential data, including blood type or allergies.

The thing is, medical IDs are like portable records that can be quickly retrieved in an emergency. They can be used in different situations where medical information is crucial to help save or treat a person. For example, dog tags have been used for many years as a form of identification to identify fallen soldiers or those left behind on the battlefield. Later, red medical nameplates were adopted to indicate that the wearer has an underlying medical condition. They display critical information, especially when a soldier requires treatment or may be incapacitated.

Who should use them and important signs

People with chronic medical conditions should seriously consider using medical IDs. These conditions include type 1 and type 2 diabetes, heart disease, seizure disorders, and respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), allergies, autoimmune diseases, and blood disorders. Additionally, people with implanted devices, such as pacemakers, insulin pumps, or defibrillators, should consider labeling themselves, as should those with dementia or Alzheimer’s disease, as they may not be able to communicate effectively in an emergency. .

The most common symbol on medical identifications is the Rod of Asclepius, a solitary snake coiled around a staff. It is the most recognized symbol of medicine associated with Asclepius, the Greek god of healing. Medical and healthcare professionals recognize this symbol and when they see it, they immediately know that the user has a medical condition and that crucial information is available. Another symbol that can be used on medical identifications is the Star of Life, which is a six-pointed blue star on a white background. The central part presents a rod of Asclepius. Any of these symbols can be used on a medical identification. It’s also helpful to know certain abbreviations, such as ALGY for allergy, T1D or T2D for diabetes, and ICE for an emergency contact number. In general, these symbols and abbreviations indicate that the user is carrying vital information, such as known medical conditions, medications, blood type, and emergency contacts, to help healthcare professionals respond to an emergency or treatment procedure.

In short, medical IDs are vital labels or emblems that provide critical information about the wearer’s medical condition. The information helps first responders and healthcare professionals treat the patient appropriately, accurately and quickly, especially at times when the individual is unable to communicate.
