We decided not to reregister for a GP up in Durham.
The last time dd saw a doctor for anything other than a non-urgent (read could wait to end of term, eg one was a mole check) was aged 8yo, and she's only been 2-3 times since then for non-urgent care. And our surgery does a very good telephone consultation and can email/fax prescriptions out.
And our home surgery's full so she wouldn't get back into it if she left, even if she came back to live at home.
She is very reluctant to see any doctor, let alone one she doesn't know, so I suspect if she did need to see one that badly, she'd be ill enough to either be sent to A&E or me to need to go and fetch her home.
