That's great, thank you newyearhere. Will print off and drop in tomorrow when I'm at the midwife. Was wondering how to ensure effective opt-out, so a pre-done letter with both required codes cited is incredibly handy.
Ok, I'm going to be very naive here, but what is honestly the worst that can happen?
It's going to include NHS number, date of birth, postcode and gender. That's not what most people would regard as very anonymous, and it will be extremely detailed data on every aspect of your medical history - mental health, serious illness, vaccinations. Everything. It is not being widely advertised, the junk mail leaflet is dropped through doors with very vague info and no details on how to opt out, and once on that system (many people won't even know they were put there) you apparently cannot opt out. And none of it is used for your own benefit. None of it will be available to any healthcare professional outside your GP practice - "approved researchers" hasn't been clarified, either. But it includes commercial entities - drug companies and insurance companies - neither of whom have reputations for the most stellar ethical standards.
we simply choose to share or not to share.
Nope. You are assumed to want to share unless you write a letter to the contrary. Nobody will ask you, and no opt-out form is provided by the state. And if you don't opt out before being entered on the system, according to the link newyearhere provided you cannot get it removed later - despite never having agreed in the first place.
