There is a report in Pulse that the NHS Population Demographics Service (PDS), the NHS’s online address book, has been storing door entry codes for vulnerable patients in the first line of the address. The result was that these codes were printed on envelopes for mailings, putting the patients at risk.
This is not the first problem with PDS, which is a major target for private eyes wanting to trace people as it has details on the whole population, including ex-directory phone numbers. You can opt out of having these details visible but very few people know that they can, and few GPs know to advise vulnerable patients to do this. We know of a case, for example, where a woman was tracked down and seriously assaulted by an ex-partner after he traced her through PDS; it never occurred to her doctor to opt her out.
