A doctor once thought my dad was my husband. I was mortified
Me too! When my Dad and I used to meet for lunch or coffee when we both worked in the city people blatantly assumed he was my Sugar Daddy as he was a bit of a silver fox and I was bleached blonde at the time. He'd get approving nods and congratulations from men and I got death glares from women. If anything was ever said we'd correct them, but I mostly made a show of addressing him as Dad as loudly as possible without being ridiculous.
dr 1 failed to confirm identity which could have had data protection ramifications
Not just that, but clinical implications too. There are many good reasons you should always be asked to verify exactly who you are when you go to A&E or a medical appointment.
And for those posters despairing of NHS training courses for staff - it's actually a full time job just training in one specific area. Staff are trained when they start somewhere and then will have annual, biannual or triannual updates depending on the course. It's not like they're always having courses, but there are a LOT of people employed by the NHS.
And despite training, you'd be surprised by the amount of staff who just. Don't. Get. It. And fail to correctly identify patients. Search the news websites, even something as trivial as a mistake in a name or address have resulted in patient deaths.
Getting the identities and details of patients and their representatives correct is absolutely vital.
OP you should definitely give feedback either through the friends and family test (Google it) or PALS. This sort of feedback is invaluable to trusts, especially when given calmly and constructively. Ignore the posters shouting you down - at any of the trusts I've worked at we would have wanted to know this!
