Maybe I am being too superficial but I do not see the problem. If you take the time to log in, review a lab, and take care of a potassium of 7 why would you not also take the time to send the covering doctor a message saying you took care of it? The best way to handle coverage (for those of you lucky enough to have it) while you are gone is let the covering doctor cover. If you do not trust the other doctors in your group to do things the way you think they should then it is time for someone to go...them or you.
