It's a terrible story for so many reasons:
- The fact that the radio station thought it was acceptable to attempt to obtain information about a patient's medical status by pretending to be a member of the family.
- Ignoring the whole Royal thing, the patient in question is a woman expecting her first child, and was severely ill, which must have been frightening for her and her family (miscarriages being very common in the first 3 months)
- Bearing in mind the Royal thing, the father-to-be lost his mother partly down to press harassment, and now he's seeing similar levels of media jackassery with his wife
- Surely the DJs must have realised that if they were successful, they'd be putting people's jobs and professional reputations on the line. And imagine how bizarre the situation is for the nurses - even if you think the situation is a bit iffy, would you accuse the Queen of not being the Queen, and refuse to put her through? It sounds like the palace could have done with bearing this in mind in advance, and told the hospital that the Queen would never phone, to be aware of pranksters, have some sort of security confirmation, etc.
- And finally getting onto the most important part, the nurse in question. Someone working in a hugely stressful job, in even more stressful than usual circumstances, suddenly put in a situation where she's been internationally ridiculed for being so gullible, and having her professional integrity questioned for not performing proper security checks. Now she's dead. Awful. Even if she was already in a depressed or vulnerable state of mind, this was a situation that possibly pushed her over the edge that could have been avoided.
