It’s my understanding ambulances also report to CMED when responding to a call. Which makes sense when you consider CMED’s need to allocate resources. Keeping track of the ambulances amount of activity helps determine when any particular hospital may become maxed out, redirecting an ambulances intentions to use a particular hospital. Ambulances prefer to deliver to the closest qualified hospital both out of a concern for patient care and quicker turn-arounds. Commercial services are in the business of making money-more calls equal more billings… it doesn’t enter into any CMED decisions on what hospital to use [as patient care takes priority] but it helps logistically, both the ambulance services and the need for the oversight CMED provides. That being said, in most cases, each call an ambulance is dispatched to is relayed to CMED. Anyone interested in monitoring ambulance dispatches should be able to monitor CMED and learn of each call. They may or may not give the address of the call, maybe they just report they are responding to a medical call and what type of medical call in a particular town or city, but since I don’t monitor CMED I can’t speak to exactly what info is given to CMED. These CMED notifications are at the very least, a work-around when the ability to monitor the ambulance company’s calls are blocked due to encryption or the use of proprietary properties on a particular radio system they may employ. A caution about monitoring CMED is that patient medical history may be divulged, either in their initial report to CMED or the patch channel CMED assigns to the ambulance to communicate with a hospital directly. Patient history is protected by law. It should not be divulged to any unauthorized entity. So, if proprietary medical history is overheard on any CMED channel, it’s imperative it not be repeated by those of us who monitor ambulance services. My take on this is if I monitor CMED anything I hear goes no further, I won’t even mention an ambulance request had been issued.
It brings up an interesting point however. In my town. I CAN hear the initial ambulance dispatch. That tells me where they are going. If it’s in my neighborhood I can usually put a name to the address. And after the hospital patch has been established on CMED, I will hear the patient report the ambulance gives the hospital and any directions the hospital gives the ambulance. All of which is “patient medical history”. Since all of CMED’s activity is “in-the-clear”, why hasn’t there been a push to encrypt CMED?
