Doctors' practices will be open as normal tomorrow following the widespread NHS cyber attack - but patients are being warned that there still may be some problems.

A statement issued on behalf of the NHS trusts in Cumbria say that while practices will be open as normal many are still bringing their systems back online.

The IT problems started affected trusts up and down the country on Friday afternoon and have left services in chaos throughout the weekend.

Staff working in hospitals were told not to turn on their computers in a bid to protect services from being hit further.

Despite working around the clock over the weekend NHS staff have not been able to completely fix the problem.

A statement read: "Some practices will not yet have full access to patient records, prescriptions, appointment systems and in some cases telephone systems.

"As a result the NHS is asking patients to consider carefully if they need a GP appointment on Monday or Tuesday, and if it is something that can be delayed to a later date then to do so.

"People who have GP appointments should turn up as normal but please bear in mind that your practice may not be able to access information required to meet all of your needs, you might be asked to return at a later date and things might take longer than usual.

"If you have booked an appointment using the GP online system, it may be that the GP practice has not been able to update their appointment information."

Meanwhile extra staff were brought in to help north Cumbria's two main hospital's cope.

North Cumbria University Hospital's Trust, which runs the Cumberland Infirmary in Carlisle and the West Cumberland Hospital, had been asking for extra staff to come in due to "ongoing issues".

Patients were being asked to only use services like A&E and the CHOC out of hours facility if it was absolutely necessary.

No patient data has been lost.

A spokesman from NHS Digital national said that a number of NHS organisations were hit by the ransomware attack.

It is believed the malware used to attack the health service was Wanna Decryptor.

In the aftermath of the incident, Barrow and Furness Labour candidate in the upcoming general election, John Woodcock, urged the prime minister to ‘use the full force of GCHQ’ to protect the NHS.

In a letter to Theresa May, he said: “The NHS is the fifth largest employer in the world, its IT systems contain highly sensitive data on the entire population of our country, and thousands of lives would be at risk were its computer systems to go down for any substantial period of time.

"The full might of GCHQ, one of the top cyber intelligence bodies in the world, should be deployed in protecting the NHS from cyber attack and safeguarding patients from cyber terrorists or enemy attacks.”
