Three London NHS trusts are among those making the most errors

Three of London's NHS trusts are among those making the most errors where doctors operated on the wrong body parts or left surgical tools inside patients.

Figures show Barts Health NHS Trust had the most cases, with 17 between April 2018 and July this year. Guy's and St Thomas's and UCL had 12 each.

The NHS said these incidents are extremely rare and it is vital they are investigated when they do happen.

Wrong site surgery incidents are preventable safety instances that can have devastating consequences for the patient and their family.

People who suffer harm because of mistakes can suffer serious physical and psychological effects for the rest of their lives, and that should never happen to anyone who seeks treatment from the NHS

Each incident of this nature puts patients at avoidable risk of harm.

Although the NHS is under significant pressure, these incidents should not occur if the available preventative measures are implemented.

– Rachel Power, chief executive of the Patients Association

The NHS cares for over half a billion patients a year and, while incidents like these are thankfully extremely rare, it is vital that when they do happen hospitals investigate, learn and act to minimise risks. The patient safety strategy published in July gives NHS staff even more support to do their job and includes a new education programme and a world leading incident reporting system to reduce the risks of human error.
