Nearly 40 per cent of staff at a Birmingham hospital have witnessed a "near miss" that affected patients, a new survey has revealed.
A national survey of the NHS workforce across 121 trusts revealed medics and auxiliary staff at Birmingham Children's Hospital also often thought of leaving and were unhappy in their job.
Although the incidents of "near misses" were not identified, the report revealed a similar number of errors (40 per cent) were noted nationally.
More than a third of staff (38 per cent) working within the specialist hospital have considered quitting their jobs - compared with 35 per cent in UK - and of those, one in five left because they were unhappy at work.
But seven out of ten (69 per cent) staff would be happy to be a patient treated by the trust, compared to 56 per cent national average.
Maybe that is because 19 per cent of staff admitted they did six or more hours unpaid overtime to provide best patient care, meet deadlines and not to let colleagues down.
The findings, presented to board members by Dr Reg Pace, also revealed a significant lack of health and safety training in the trust.
Only 38 per cent of staff had had relevant training in the past year compared to 68 per cent nationally.
Dr Pace said: "The issue of staff turnover reflects the fact this is an urban trust, which usually attract a younger workforce, so it is not surprising many leave for other jobs as they climb the career ladder.
"Despite some of these results, the most important indicator for the trust is that 69 per cent would be happy to be treated by their colleagues at this hospital.
"That is significantly higher than the national average and shows staff take pride in providing the best possible care."
