A hospital trust has reported five never events this year - including two cases where swabs were left inside patients.

Queen Elizabeth Hospital, King’s Lynn, Foundation Trust has also reported one case of maladministration of insulin and another of wrong site surgery. It has also discovered that in 2011-12 it extracted one more tooth than had been agreed with a patient undergoing complex root work, and this has had to be reported as a never event.

Three of the cases occurred in August, including a case where a patient with two small scars on his lower back and buttock came into hospital to have one of them excised. The wrong scar was excised and the patient then had to have the correct one removed.
