Two NHS hospitals have put up posters in operating rooms reminding surgeons to check they have the right patient.
This comes after the Oxford University John Radcliffe and Churchill hospitals carried out four mishaps between May and June.
These so-called ‘never events’, which are defined as incidents that would not occur if proper guidance was followed, included surgeons inserting an endoscopy camera into the wrong patient.
Another incident saw medics leaving a surgical cup inside a patient, requiring they go under the knife again the same day.
A trust spokeswoman said: ‘These poster reminders are part of a suite of actions to remind staff to thoroughly check a patient’s identity.’
Speaking of the incidents at the Oxford University’s hospitals, the trust’s medical director Tony Berendt said: ‘No clinician in our hospital comes to work to be, in any sense, careless or to cause harm.
‘I know that the teams that have been involved in these events are deeply upset about what has happened.
‘On behalf of those clinicians I would extend my apologies to all patients involved and our public for the inevitable impact on their confidence in our services that these kind of events lead to. We do take them extremely seriously.’
Across England, 181 never events occurred in 2018 alone, including a patient incorrectly having her ovaries removed.
Other incidents see patients unnecessarily having laser-eye surgery, bowel examinations or overdosing on the wrong medication.
Kate Andrews, news editor at the Institute of Economic Affairs, told The Telegraph: ‘Substantial reform of the system, so it better focused on patient care, would likely reduce the number of “never events” that occur each year.
‘Sadly, with no meaningful plans for reform on the agenda, completely unnecessary – and largely frightening – errors like this continue to occur and are failing to decline.’
Some 467 never events were recorded in England in 2017 compared to 466 the year before.
NHS Improvement’s executive medical director and chief operating officer Dr Kathy McLean argues never events cannot be compared year-on-year due to the definition and policies surrounding such incidents being updated regularly.
This comes after a report released last February suggested surgical sponges were left inside a woman up to nine years after her C-section.
The unnamed woman, 42, believed to be from Chiba in Japan, went to her doctor complaining of bloating that had lasted three years.
A scan revealed two gauze sponges had become attached to her large intestine and the tissue that connects the stomach to other parts of the abdomen.
Scientists believe the sponges were left behind after one of the patient’s two C-sections, which took place nine and six years ago.
Due to the sponges not being attached to her uterus, the patient would have been able to conceive a second time without problems.
Following the removal of the sponges, the patient’s symptoms improved. She was discharged five days after her surgery.
