Don't be daft, why do the obvious when we can have: all responders living in constant dread of a false accusation; potential for the odd case where someone does get out-of-bounds with a patient (dear old Shipman proved that practicing medicine doesn't = saint, as did Beverly Allitt). We can then deal in the classic manner of this govt by making surveillance the answer, lose loads of videos which end up online, thus causing some people to avoid calling for help even when it's badly needed.... and on we all go, doing anything but fixing the problem. God, if cynicism was a disease I'd need an ambulance right now, but this is just SO predictable....
