NHS England London published its weekly update on the clinical impact of the ransomware attack on pathology services provider Synnovis on Friday 19 July, covering the week ending 14 July. In that week, 1,028 hospital outpatient appointments and 71 elective procedures were rescheduled at King's College Hospital NHS Foundation Trust and Guy's and St Thomas' NHS Foundation Trust, alongside 24 community outpatient appointments1.
The cumulative totals since the attack on Monday 3 June now stand at more than 7,000 outpatient appointments and over 1,500 elective procedures postponed across the two trusts1. Of the 71 elective procedures postponed in the latest week, two were cancer treatments, compared with five the previous week. The update states it is too early to understand the impact on 62-day performance or the faster diagnosis standard for the affected trusts1.
| Measure | Latest week (ending 14 July) | Cumulative since 3 June |
|---|---|---|
| Hospital outpatient appointments postponed | 1,028 | More than 7,000 |
| Community outpatient appointments postponed | 24 | Not reported |
| Elective procedures postponed | 71 | Over 1,500 |
| Cancer treatments among postponed procedures | 2 | Not reported |
| Organs diverted to other trusts | 26 (30 the previous week) | Not reported |
| Pathology capacity | Around 54% of normal | Not reported |
South east London pathology services provided this week remained at around 54% of normal capacity. No planned caesarean sections have been postponed or rescheduled in the last two weeks. Primary care appointments are going ahead as normal, but blood tests are being prioritised for urgent cases, and GP referrals are significantly affected, with only urgent referrals accepted for blood sciences; normal services are operating for histology and cervical smears1.
Guy's and St Thomas' has restarted outpatient blood tests and is contacting patients to book appointments in order of clinical priority as capacity increases. Guy's and St Thomas', King's College Hospital and South London and Maudsley NHS Foundation Trusts remain in a critical incident, while Oxleas NHS Foundation Trust, Lewisham and Greenwich NHS Trust, Bromley Healthcare and primary care services in south east London continue to be significantly impacted1.
Dr Chris Streather, Medical Director for NHS London, said:
"Thanks to the hard work and dedication of everyone involved in maintaining services affected by last month's cyber attack on pathology services provider Synnovis, most services are now working at near-normal levels, including in outpatients, day cases and non-elective care."
NHS Blood and Transplant are calling on O Positive and O Negative donors to urgently book appointments at one of the 25 town and city centre NHS Blood Donor Centres in England. Its director of donor experience, Mark Chambers, said the service is experiencing higher than usual pressures on maintaining stocks of O Negative, the universal blood type, citing the cyber incident and variable weather conditions affecting sickle cell patients1.
Why it matters for households
The disruption is concentrated in south east London. Patients at Guy's and St Thomas', King's College Hospital and South London and Maudsley remain under a critical incident, and services at Oxleas, Lewisham and Greenwich, Bromley Healthcare and local primary care are still significantly affected1. NHS England London advises people to access services in the normal way, dialling 999 in an emergency, to use NHS 111 through the NHS App, online or by phone for non-urgent care, and to attend booked appointments unless contacted to say otherwise1. A helpline has been set up for people affected: 0345 87789671. Blood donors can book at blood.co.uk or on 0300 123 23 231.

What happens next
NHS England London says updates will be provided on a weekly basis as the incident continues, and that the NHS will continue to provide updates as more detail becomes available through Synnovis' full investigation1.
