The puerile call made to the hospital looking after the Duchess of Cambridge seemed hilarious to some, in particular the two Australian yahoo's that did it. It wasn't funny and it certainly wasn't clever although those two pricks seemed to think so.
Systems should have been in place to ensure that such things (common enough) could not happen. They usually are, when people with even a moderate threat assessment are involved. A simple solution usually involves the use of a simple password, known only to the principals and those very close to them. My short post a few days ago, on this incident, made that aformentioned point. The fact that people in the chain of events who were solely employed to look after the well being of patients in hospital were subjected to this failure is part of a greater failing completely outside their remit - and that should have been made clear to them from the outset.
Blame is like flying shrapnel and can be indiscriminate. Managers are there to shield their subordinates from this, to keep the paths of the frontline workers clear of obstructions so as to enable them to get on with their work and to support them when systemic failures occur - in health care everything else is subordinate to the care of the patient, or should be. I'm sure the manager of the Aussie radio station will be looking out for the mental anguish of his/her `subordinates in their time of anguish, once they are woken up with this news. For a dedicated nurse who took this failure very personally, a woman of honour, it is too late.
As a dear departed friend would have said, `It is to weep`.
