Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
As a patient my major concern relates to access to this data.
While this data could be a valuable asset w.r.t. to epidemiological research it could, in commercial hands, be "cherry picked". As shown, this is a general fear
"..............low awareness of how data are used within the NHS, let alone by academics or commercial organisations.(7(Ipsos MORI. The one-way miror. Public attitudes to commercial access to health data 2016 www.wellcome.ac.uk/publicattitudes)"
It is imperative that all such data is protected from commercial interests but be available for truly independent research.
