While it sounds like a great idea and may have use in the hospital, I have my doubts as to its value in the pre-hospital setting. There are enough of us here on the forum involved in EMS that can give you varying points of view, allowing you to decide the value of this card. What I mean by the card’s limited value in the field is not that the information would be of limited value, but the ability to locate the card on your person and the ability to read the data, may limit its value. All EMS providers when examining a patient that is either unconscious or having a level of conscious so limited that we are unable to ascertain vital medical information will look for a Medical-Alert bracelet, tag or other alert device. If the patient is critical or has been involved in an accident and is unable to answer questions, generally our first priorities are the ABCD’s that have been discussed before in other posts. If there are enough personal on the scene and if someone has the time they may look for ID and other documents of a medical nature in your wallet, but many times a Law Enforcement Officer has taken possession of the wallet and it is not readily available to us to look for this card. If the individual also had some type Medical-Alert device advising the card was located in the wallet, it might have more value. I would like to hear from other EMS providers on this forum as to their opinion of the card for the pre-hospital setting. Pete
