The United Kingdom has not adopted a HIPAA "like" policy that protects patient privacy and, as a matter of fact, the UK does not feel the same need for privacy and other human rights that the US embraces (we had a war over this, remember?).
Remember the prank call where the radio show host posing as the Queen called the hospital for info on the pregnant Kate, wife of prince William? That ended with a suicide and some firings. In the US, that would have ended, at worse, with the firing of the person that divulged the info. More than likely, the "queen" would have been informed she needed to prove her identity and ask Kate to be added to the disclosure list signed by Kate.
And while we're on the subject, your private (or public) insurance provider has TONS of information on you (diagnosis, meds, treatments). Be aware of when you assign rights for others to see your Protected Health Information (PHI). If someone gets your info in the US without permission, warrant, or, in an emergent setting, REPORT THEM! (and then sue).
Sorry, we have a great system here in the US, but we all need to make it work and quit complaining.
