Of these, 166 incidents involved wrong-site surgery, including 40 cases where treatment was carried out on the wrong side or part of the body.
Seventeen patients received procedures intended for someone else, and in one case, a patient had an organ or body part removed when the plan had been to conserve it.
A total of 121 never events involved foreign objects being left inside patients following procedures.
This included 26 guide wires, two cotton wool balls, 22 surgical instruments, and 53 swabs—made up of 21 surgical and 32 vaginal swabs.
Other incidents recorded included eight cases where a procedure was not part of the surgical plan, and four cases where the wrong procedure was performed entirely.
Six patients received incisions in the wrong location, 30 received injections in the wrong place, 38 had nerve blocks administered on the wrong side, and 22 had the wrong skin lesion removed or incorrectly biopsied.
Another 50 incidents involved the wrong implant or prosthesis, including 14 knee implants, nine eye lenses, and four hip devices.
The total number of 403 incidents for the year is the same as for the previous year.
An NHS spokesperson said: “NHS staff work exceptionally hard to keep patients safe and incidents like these are extremely rare, but when they do occur NHS trusts are required to investigate what has happened and take effective steps to learn from them and make improvements.”
NHS staff uniform controversy
NHS staff should not wear political badges at work or take part in political marches while wearing uniform, the head of a review into antisemitism in the health service has said.
Lord John Mann said badges professing support for Palestine or Israel should not be worn while people are at work in the health service, describing it as “a problem” in the NHS.
As the Government’s independent adviser on antisemitism, he was tasked last year with looking into antisemitism in the NHS and has made a series of recommendations.
