No POA and putting a note about my concern on her records was the most they would do. And that was a mammoth task. I asked them to call her in for 'routine' tests that included memory, but they wouldn't. And she has been refusing point blank to go. They won't do anything unless she asks for it because of patient confidentiality/data protection etc, etc, etc. Which is really annoying, as I know other GP surgeries HAVE called patients in for review when relatives have expressed concern, so it's obviously something that is down to the discretion of the surgery.
They actually told her the bloods were to check memory and diabetes so I think it must be so. It's not a UTA - she's had those a lot, but this is something that's been coming on for years and getting steadily worse.
