NHS figures show 629 blunder operations and other mistakes that should never have happened
SubscribeDoctors have operated on wrong body parts and left surgical tools – including surgical gloves, chest drains and drill bits – inside patients. Hundreds of patients have suffered due to NHS blunders so serious they should never happen, new data shows.

Wrong body parts removed and items left inside patients
Some 629 “never events” occurred in NHS hospitals between April 2018 and July this year – the equivalent of nine patients every week, according to data obtained by PA news agency.
The figures show doctors have operated on the wrong body parts and left surgical tools (including surgical gloves, chest drains and drill bits) inside patients many times over.
One patient had the wrong toe amputated, while another had the wrong part of their colon removed.
Two men were mistakenly circumcised, while a woman had a lump removed from the wrong breast and two others had a biopsy taken from their cervix rather than their colon.
A further six women had ovaries removed in error during hysterectomies, plunging them into menopause.

Some Trusts have higher rates of never events than others
Professor Derek Alderson, president of the Royal College of Surgeons, said such mistakes are “exceptionally traumatic for patients” while the Patients Association described them as “devastating”.
The figures revealed how several patients had procedures intended for someone else, including colonoscopies, lumbar punctures and laser eye surgery.
Other potentially fatal mistakes included patients being given ordinary air rather than pure oxygen, and people falling from poorly secured windows.
Some patients were given overdoses of drugs including insulin, while others had feeding tubes misplaced and put into their airways.
Medics also transfused the wrong type of blood to six patients, while 52 people had the wrong teeth taken out.
Overall, 270 incidents related to wrong site surgery, while 127 were “foreign objects” left inside people after operations, including specimen bags, needles and swabs.
The figures, which are provisional, showed that some NHS trusts have higher error rates than others.
