An estimated 200,000 people have requested or downloaded opt-out documents for the NHS Summary Care Record (SCR), according to a campaign group.
The Big Opt Out, which is campaigning against plans for a national database of patient information, told the Daily Mail there had been 200,000 website downloads or requests for letters which people can send to their GPs asking for their medical details to be withheld from the database.
The campaigning group has not, however, offered any estimate on how many people have subsequently completed the form or sent it to their GP.
In the initial pilot areas of the SCR, Connecting for Health, the NHS IT agency responsible for the project, says levels of people requesting opt-outs have been very low.
