The post has just come and there was a letter for me from the NHS telling me about a Summary Care Record that will be created unless I opt out of it

It says that all information will be confidential, and yet they send a letter addressed to me with my full name including my middle one on the envelope

I'm not sure whether to opt out though it all seems a bit "big brother" to me added to the fact that on numerous occasions I have had other people's records when I have been in hospital, I find it all a bit worrying. I know I'm fairly alone with this, but I'm sad to say I have no faith in the NHS at all for various reasons

What do you think Is this countrywide or just something the local NHS is doing here.
