Same with my OH's cancer treatment. He has ongoing battles every month with the oncology dept and the hospital pharmacy to get appointments at the right time and in the right order and to get his chemotherapy drug prescriptions issued on the right date. It must take 10-15 phone calls every single month to different people to change the appointments they set (for the wrong dates and in the wrong order) and to chase the prescriptions to be approved and issued.
It "should" be simple and straightforward because it's a chain of events that happens every month, but the NHS is incapable of setting it up in order and not only does he have to phone several different people each month, he has to go through the whole rigmarole of explaining to them why appointment x has to be before appointment y and all z number of days before treatment start date - it's as if they've never heard of it before, as it's always different people he ends up talking to, as if it's the first time they've done it.
It's basically almost a full time job for one week every month as of course, it's hard to find the right people to talk to, messages are left for call backs which don't happen etc.
Sometimes, he ends up having to phone his "named" cancer nurse specialist who is really there for medical problems, but he has to get her to help him with the administration side of things when he gets nowhere after a few days of trying.
Sometimes, after a slight "tweak" to the drugs agreed with the haematologist, the prescription hasn't been changed, so he knows to check and question every little thing they do. Only this week, he picked up his prescription (which consists of several different drugs) to find two drugs missing - he knew he needed them and no discussions had been had to discontinue them, so again, he had to spend a morning phoning around trying to find who had changed the prescription and why, only to find it was yet another admin cock up, and that they should have been issued!
Luckily he's healthy enough and confident enough to take control, he knows what has to be done, by when, etc., so basically manages himself and his treatment is working exceptionally well - even his haematologist is surprised as she was talking about lifespan of 2-3 years when he was first diagnosed and that's now 7 years ago!
But we've said many times how awful it must be for people who are unwell and can't manage/advocate for themselves as they'd be at the mercy of the shambles, and would be turning up for wasted/unnecessary appointments, starting the monthly treatments late, risking the wrong prescriptions, etc. People who just blindly think the NHS "knows best" and just follow whatever appointments are made and drugs issued are at a real risk of damage to their health. It shouldn't be that way!
