Ambulances are no longer being diverted from Addenbrooke’s Hospital, in Cambridge, after “significant issues” with the computer systems were fixed by technicians.

Officials at Cambridge University Hospitals, which runs Addenbrooke’s, had earlier asked people not to attend A&E today (Tuesday) “unless absolutely necessary”, amid a computer crash.

But, at about 2.15pm, the hospital said the issue had been solved and said ambulances were no longer being diverted, though the A&E department remained “extremely busy”.

At Hinchingbrooke Hospital, in Huntingdon, meanwhile, officials said its A&E department was also “extremely busy” and called on residents to consider alternative options, including calling NHS111 for advice, Doddington Minor Injuries Unit, or St Neots walk-in centre.

A spokesman for Cambridge University Hospitals said: “The computer network system at Cambridge University Hospitals is back up and running, although the trust continues to work closely with its suppliers to monitor the situation.

“Ambulances are no longer being diverted to other regional hospitals and we would like to thank our health partners, staff and patients for their support.

“The public is advised that the Accident and Emergency department remains extremely busy and elective surgery is cancelled for the day as the hospital gets back to normal. Outpatients should assume that appointments are going ahead unless advised otherwise.”
