My husband had a very similar situation to Corner gran - in pain for years with deteriorating knee joints, to the point of wishing he was dead, due to the pain, being unable to walk or work, and being fobbed off by the GP, who refused to refer him for surgery. Fast forward to him being in ICU with covid and a decent person in charge of the discharge process, who picked up on his mental state as well as seeing the x-rays of his knees. Those were several years old, and her opinion was that his knees were severe then! The outcome was a very strongly worded letter from her to the GP, and hey presto, both of his knees were replaced by the end of last year.
There is clearly no joined-up practice in patient records, as this week he has received a text from the GP practice saying as he hasn't had his blood pressure checked for over 5 years, he needs to make an appointment for that. Duh - he was in ICU covid ward 18 months ago, when daily blood pressure checks were done...... Sorry, but I have no faith in the GP system as operated by our local practice. No wonder once we've got past the hurdle of actually being referred, that the hospitals have to double check the GP's input.
