I'd ask your IM what normal practice is.
yep, this is what i would be doing too. she/he might have a system that they use and contacts to get in touch with regarding this.

From what you have said, it sounds like the person you spoke to was just a bit confused about the process. that's ok, HB is not on the radar for alot of people. I guess the best is to explain that this not a shared care arrangement (all your BTs and ultrasounds etc can be arranged with your GP and IM). what you are needing is a file and a patient number to make transfer easier. As they would be your closest hospital in need of transfer it is best if they can arrange that for you.

That said, if your IM has all the paperwork in order and all the results etc from any pathology/US etc then that will also speed up the process regardless.
