Ronib I've had two hospital discharges this year. The first time I was sent home with enough drugs to last me for a couple of weeks, my GP was sent notes on my discharge and information about how to reduce the pain killers slowly so I did not suffer withdrawal. It went very smoothly except it was sometimes difficult to get hold of the drugs but that's another story.
The second time I wasn't given any drugs so I had to wait for my notes to get sent to the GP. There was a delay so my GP suggested I chase it up myself which I did by contacting the consultants secretary. The meds were changed again at a clinic appointment, this time I was given a prescription to hand in to my GP, I had to wait for the GP to sign it off and then for the pharmacy to put them up, basically took the best part of a week! I find the NHS app really useful as I can see if notes have been added and if my prescriptions have been updated. I can also send the GP messages via their website and find they deal with them really quickly but nothing flows as quickly as it should and if there's a weekend or a bank holiday everything gets slowed down even more. I think my GP surgery is pretty good so I imagine it can be much worse at other surgeries.
