I have mixed experience and feelings about this. I hate trying to contact my GP, or get anything done via that route because it is so difficult.
My SIL has a history of gynae issues, and has a private scan annually as a consequence. The NHS doesn't provide this sort of 'catch it early so we can investigate anomalies' service, even for someone with her history, so the query fibroids/query tumour changes in her uterine lining would not have been detected unless she went private. She's now being referred to an NHS hospital for an urgent surgical investigation, possibly operation, because she was able to go to the GP with her scan results. The GP was insisting it was all just menopause and would settle down, if only SIL would take HRT.
On the. other hand, my really very old parents (88 and 93) have had excellent care across a range of specialties, both hospital and community based. They've had OT assessments at home, they've had GP visits at home, district nurses coming round to do dressings after a fall, thousands of pounds of dental care for no cost to them. My mother has CML, and is in remission 6 months after diagnosis because she is benefiting from an amazing breakthrough drug which became available only about 15 years ago, which doubtless cost the NHS huge amounts to buy it when it was still on patent. My father, who has prostate cancer, was experiencing some changes in his condition, and his consultant advised going to A&E and waiting in-house for an MRI scan, as being the most effective way of identifying any really critical changes.
So I took him, and yes, we did wait 7 hours to get the scan, and we did leave before a doctor was able to review it and make a decision, because after 9 hours on a hard chair, my dad had really had enough. But when I first began working for the NHS, over 30 years ago, there were 2 MRI scanners in the country, and the waiting list to use them was about a year. My father got a scan on the same day that the consultant advised it, basically by rocking up to A&E, reporting a bit more pain and deteriorating bladder control, and being willing to hang around.
So not sure what my conclusions are really, except that we are asking a huge and ever-growing amount of the NHS, for a population that seems to be getting older and sicker.
