Oh totally
I had a thread about mum being in A&E overnight for 16 hours after a suspected heart attack.
The written report that followed could honestly have belonged to another patient. Maybe it did? We flagged it up, got several calls from other depts who were expecting to see her because she'd been referred for a bunch of conditions she doesn't have.
I now think it wasn't a mix up. It was a deliberate cover up so they didn't get in trouble for leaving a suspected heart attack patient alone for so long.
In previous years, mum has been in hospital and told she must take a medication that she is allergic to. Dad and I had to battle to stop it, taking it in turns literally standing guard at her bed while the other one ran around the hospital trying to get it corrected.
A friend was very ill a few years ago because in spite of a bracelet warning she's allergic to penicillin - essential to know as she has a chronic health issue - she was given it after hospital admission. Took weeks to recover. It would have been all over her records too.
