There is an opt out website for this computer system which also has a letter you can print off and send. http://www.nhsconfidentiality.org l printed off the letter ages ago and sent it to my Dr telling them that l did not want my details going onto any database other than the inhouse one it was already on. My Dr acknowledged the request with the comment that it seemed the wisest course to take. As to government logging our details if we opt out l should think they do that already for 1000s of other things they have dreamt up so what's new?
