not at all.
yes - those computerizing stuff.... that's within hospitals. It's not the same as national ID however - in Denmark, they do have centralized database for health records... meaning any hospitals/physicians can retrieve your medical file and see your medical history. That will never happen in America because we value privacy and despise anything that reeks of Big Brother.
Right now - your record is done by papers and kept at filing cabinet. Because of that - that takes time to retrieve it and it costs money to store many files. Because of that - there's a high chance of errors such as doctor prescribing you antibiotic but didn't see that you are allergic to specific antibiotic in the file because your medical file is too thick or maybe the handwriting was too messy to read. Because your medical file is not easily accessible, your hospital stay is longer and some diagnosis are repeated and more time is wasted... thus causing your medical bills to run high.
With computerized system - the computer will warn doctor that you are allergic to certain antibiotic.
