Nurse Victorino Chua killed and poisoned patients he was supposed to be caring for. In his own words he was "an angel turned into an evil person".
Judith Morris is the Director of Nursing and Midwifery at Stepping Hill Hospital.
She said the hospital carries out a number of checks on new nurses joining the hospital, and the case had an emotional impact on staff and patients.
