Up to 20 NHS trusts have shared patients’ private medical information with Facebook through a hidden tracking tool on their websites.
The Observer found that data was collected from individuals who accessed NHS webpages related to HIV, gender identity services, self-harm, sexual health, children’s treatment, cancer and more.
The websites of 20 NHS trusts were found to be using the Meta Pixel tracking tool, which gathered browsing information and shared it with the social networking site.
That is despite the trusts promising not to collect that information without obtaining proper consent from the individuals involved.
