1) I didn't get any pain meds for my neck injury from an MVA 2 weeks ago at the other hospital and I'm hoping you will be nicer.
2) I had surgery last week at another hospital, now I am having problems, and your hospital is closer.
3) I didn't like the way they treated me at XYZ hospital.
4) The wait was way too long at the other place
5) I want a second opinion.
6) They didn't do anything for me over there.
7) Family is not happy with care of other doctor, hospital, etc.
ER hoppers are sometimes dumb enough to tell us they were at another hospital. Then there are those who don't. They think we won't find out. But BEWARE, these days we can see if you have been to another hospital in our system. We are also connected to other hospitals as part of a network that shares info, with your kind permission of course.
When I ask people why they didn't go back to the hospital that treated them before, did surgery on them, they are often offended, like I shouldn't ask that. It should be okay to come to a hospital that has no records of your surgery, history, etc. Sorry if I think thats stupid.
