King's College Hospital NHS Foundation Trust and Guy's and St Thomas' NHS Foundation Trust postponed 25 acute outpatient appointments and two elective procedures in the 13th week (26 August to 1 September) since the ransomware cyber-attack against pathology services provider Synnovis.

In total 10,129 acute outpatient appointments and 1,702 elective procedures have been postponed at the trusts since the cyber-attack.

Chris Streather, NHS London medical director, said: ‘We continue to see fewer acute outpatient appointments and elective procedures being postponed at Kings College Hospital NHS Foundation Trust and Guy's and St Thomas' NHS Foundation Trust.'

He added: ‘Our focus is the full restoration of blood transfusion services which remains planned for early autumn, meaning that mutual aid will continue to be required for planned operations and transplants to minimise the ongoing impact on patients until this time.

'The repatriation of testing services for GPs back to Synnovis continues to progress and South East London ICB look forward to repatriating services for all boroughs as soon as possible.'
