I'd be surprised if that code system was even in use very much by EMS. It's just too much to memorize for a busy EMS crew. In my neck of the woods, information transmitted between medical staff in the field and the hospital is generally limited to a brief verbal description, trauma codes green, yellow, and red, which are pretty close to self explanatory, and patient classes 1 thru 4, 1 being minor injury/complaint and 4 being dead. Plus of course, code 99, cardiac arrest in progress. And where applicable, GCS score.
Anything else that needs to be communicated gets a verbal description. Such as:
"Mercy, Hospital, this is Rescue 93 enroute to your facility with one Trauma Green patient. Patient is a heavyset female, 62 years of age, with no significant prior medical history. Chief complaint is a Lawn Dart lodged in the orbital ridge above the right eye, without ocular involvement, with a secondary complaint of a Victor rat trap on the first and second digits of the right hand, up to the second knuckles, with dislocation deformity noted in the right index distal phalangeal joint. Both injuries are the outcome of a Truth Or Dare type game at a family reunion party in Union Park. Patient is ETOH and surprisingly uncombative. GCS score is 456." "Mercy copies, Rescue 93. We'll get you a bed assignment after we all stop laughing over here. "
So how would you write that out in PDC codes?
