To add to this thread, with the code the developers put on the cardiac arrests (9-E-1, or any other 9 code) the destination should be closest ER, no trauma requirement, as the code indicates a medical related arrest. If they want to add a trauma requirement for an arrest, they need to be coding them as one of the following: 3-D-1, 4-D-1, 13-E-1, 13-E-2, 17-D-2, 21-D-1, 27-D-1, 29-D-6, 30-D-1. All of these codes are associated with traumatic injuries, with the priority letter and info number indicating arrest. If they only want to pick one, I would go with 30-D-1 as its code translates to Traumatic Injuries: ARREST.
As for the accuracy of which hospital the rest should go to, the trauma centre requirement needs to be removed for accuracy. All ERs are equipped to deal with these emergencies, to stabilize the patient before sending them to a more appropriate centre. A cardiac centre would be a destination if ROSC is achieved, but for that, they need to create a new call that an arrest can convert to.
