This would be enormously expensive. The number of things an EMR thinks are an imminent threat will vastly outnumber the things that actually are thanks to liability concerns. So now you need an extra on-call doctor just to filter out the false positives, or the on-call doctor gets notification fatigue and ignores them. Or in the best case you send a lot of people to ER in the middle of the night for no reason. Again thanks to liability concerns, but this time on the part of the primary care practice.
