The Information Commissioner's Office (ICO) has recently taken action against Great Ormond Street Hospital following a breach of data protection where letters containing details of patients’ treatment were sent to the wrong addresses. In three of the four cases, the letters were sent out by temporary staff who had not had any data protection training.

The case shows the importance of ensuring that all staff, whether temporary or permanent, are properly trained if they are going to have access to personal data.

The ICO's news release and undertaking signed by Great Ormond Street can be found on the ICO's website.
