Several London hospitals, still under significant strain more than a week after a cyberattack crippled services, have asked medical students to volunteer to help minimize disruption, as thousands of blood samples have had to be discarded and operations postponed. The ransomware attack on Synnovis, a private firm that analyzes blood tests, has crippled services at two major National Health Service hospital trusts, Guy’s and St. Thomas’ and King’s College, which described the situation as “critical.”According to a memo leaked in recent days, several London hospitals asked medical students to volunteer for 10- to 12-hour shifts. “We urgently need volunteers to step forward and support our pathology services,” said the message, which was reported earlier by the BBC. “The ripple effect of this extremely serious incident is felt across various hospital, community and mental health services in our region.”The attack also disrupted blood transfusions, and the N.H.S. appealed to the public this week for blood donors with O-negative blood types, which can be used in transfusions for any blood type, and O-positive blood types, which is the most frequently occurring blood type, saying it could not match patients’ blood at the same frequency as usual.
