That's why band 5 nurses are so vulnerable - they're the lowest accountable person (and the easiest to scapegoat)
Everybody thinks they'd never ever let an innocent person (nurse) be a scapegoat for such horrors. However, theoretically, if a trust has lots and lots of deaths that were avoidable and it's known amongst senior staff and management that there have been a series of serious negligence and failures (these are usually chain reactions) - they know that heads would absolutely roll ( 'important' staff, heads of trust, executives) the impact even harder felt and more emotive when we're talking about babies and children. This would lead then to hugely expensive enquiries that would take years and years and millions of pounds, public outcry, massive media attention with the trust and managements names on front pages - people baying for blood on behalf of those poor families.
The trust and the hospital name would never recover. Those devastated families would be entitled to individual enquiries and millions of pounds of compensation between them. (And bloody rightly so - not that money crudely touches the pain )
That's one option.....or, you can fit up a 'fall guy' - Hobson's choice. Lesser of two evils for them ?
I'm not for one second saying this is what actually happened. But illustrating how it can become a choice in terrible circumstances to opt for choosing a scapegoat Vs the catastrophic consequences for them as managers/a trust to admit or even dare to admit - something they've done or not done is the cause of those deaths.
