Operations cancelled after cyber attack. BLOOD TRANSFUSION SERVICES PARTICULARLY IMPACTED.

A CYBER attack has affected some major hospitals in London, impacting the delivery of blood transfusions and leading to cancelled operations, according to staff memos.

King's College Hospital, Guy's and St Thomas' (including the Royal Brompton and the Evelina London Children's Hospital) and primary care services in the capital have been hit by a "major IT incident" involving pathology partner Synnovis, the letters said.

Synnovis is a provider of pathology services and was formed from a partnership between SYNLAB UK & Ireland, Guy's and St Thomas' NHS Foundation Trust, and King's College Hospital NHS Foundation Trust.

Trusts reported that the incident has had a "major impact" on the delivery of services, with blood transfusions particularly affected.

Some procedures have been cancelled or have been redirected to other NHS providers as hospital bosses continue to establish what work can be carried out safely.

One patient, Oliver Dowson, 70, was prepared for an operation from 6am on Monday, at Royal Brompton when he was told by a surgeon at about 12.30pm that it would not be going ahead.

He said: "The staff on the ward didn't seem to know what had happened, just that many patients were being told to go home and wait for a new date.

"I've been given a date for next Tuesday and am crossing my fingers - it's not the first time that they have cancelled, they did it on May 28 too, but that was probably staff shortages in half term week."

A spokesman for King's College Hospital in London confirmed it was affected by the attack.

The incident is thought to have occurred on Monday, meaning some departments could not connect to a main server.

According to the Health Service Journal (HSJ), several senior sources have told it the system has been the victim of a ransomware attack.

One said gaining access to pathology results could take "weeks, not days".

There are suggestions urgent and emergency care at the hospitals will be affected as they may not be able to access quick-turnaround blood test results.

In 2021, it was announced that Syn- Lab would partner with the NHS to deliver pathology services at hospitals and GP services across South East London. As well as serving King's and Guys' and St Thomas', the pathology service also caters for South London and Maudsley and Oxleas NHS Foundation Trusts and a number of GP practices, clinics and other community services across the boroughs of Bromley, Lambeth and Southwark.

Pathology services help with the diagnosis and treatment of illnesses and infections by analysing samples including blood and tissue.
