O-type blood donors needed after London cyber-attack

An appeal has been launched for O blood-type donors to book appointments across the country following the ransomware attack affecting major London hospitals.

NHS Blood and Transplant is appealing for O blood-type donors to book appointments to donate as this is safe to use for all patients.

The IT attack means the affected hospitals cannot currently match patients’ blood at the same frequency as usual.

Several London hospitals declared a critical incident, cancelled operations and tests, and were unable to carry out blood transfusions last week after the attack on the pathology firm Synnovis, which Qilin, a Russian group of cyber criminals, is understood to have been behind.

Memos to NHS staff at 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 London said a critical incident had been declared.

Now NHS Blood and Transplant is calling for O positive and O negative blood donors to book appointments in one of the 25 NHS Blood Donor Centres, external in England to boost stocks.

For surgeries and procedures requiring blood to take place, hospitals need to use O- type blood as this is safe to use for all patients and blood has a shelf life of 35 days, so stocks need to be continually replenished, the NHS said.

That means more units of these types of blood than usual will be required over the coming weeks.

O-negative is the type that can be given to anyone, known as the universal blood type.

It is used in emergencies or when a patient’s blood type is unknown.

Air ambulances and emergency response vehicles carry O negative supplies.
