That could be a good thing provided the other hospital is within a very reasonable distance. I would hate to think of the bad outcomes if this is a BLS truck that can only rely on speed when the BP is dropping or the rhythm changes to VT/VF while bypassing another hospital and is at the point of no return. It is one thing to bypass hospitals if you are ALS and have similar capabilities as to what would be initially done in an ED but it is a whole other pandora's box to tell a crew with nothing more than first-aid training and an 12 - lead EKG skill to bypass and keep going just by a transmitted piece of paper and a BLS assessment. Would they also be trained to recognize rhythm changes that might require immediate attention? They would also be speeding into the further ED with no IV access (not that they should be taking more time at scene to do that either at a BLS level) and probably a very sick patient if nothing else from a very scary ride.
No it's not a good thing. My experience with American basic life support is not first hand but I understand it to be somewhat archaic and totally inappropriate for this sort of procedure. Even here where our BLS is a mix of BLS and ILS, I would advocate it inappropriate for bypassing a facility with a suspected STEMI patient onboard.
If the transport time was LESS than a defined margin (say 15 minutes) and the patient was fairly stable in terms of cardiac rhythm (not throwing PVcs, runs of VT etc) I may consider entertaining the idea.
