The effects of a large-scale cyber attack are still being felt throughout the region's NHS services today, as healthcare providers try to get back on their feet.

At James Paget University Hospital in Gorleston, patients are being told to attend appointments as usual today, but the hack was still having an impact as staff worked with paper processes and parking was free on Monday as the car park barrier - controlled by the computer system - was up.

Today, the barrier has been repaired and parking is no longer free

Some of the systems are thought to be back online, but work is still ongoing.

MORE: James Paget Hospital in Gorleston affected by national large-scale NHS cyber attackPatients arriving at the hospital's accident and emergency department are reportedly being told they will have to fill out a registration form.

But the message from the hospital is to not go to A&E unless it is absolutely necessary, as waiting times are expected to be longer.

A JPUH spokesman said: 'Staff have been working throughout the weekend to restore our IT systems. Established back up plans are continuing to ensure we effectively support safe patient care. Members of staff arriving for work this morning will be assisting our clinical teams so patient care delays can be limited.

'I am very proud of our staff for what they have done in giving up their weekend to focus on our patients and making sure our manual systems are as effective as possible. We apologise for the disruption that has been caused.'

The Norfolk and Norwich University Hospital in Norwich was not affected by the attack, neither was the Queen Elizabeth Hospital (QEH) in King's Lyyn.

QEH Medical Director Nick Lyons said: 'The Queen Elizabeth Hospital was not affected by Friday's cyber attack and has continued to operate normally over the weekend.

'We would like to reassure patients that it is business as usual at the QEH and would urge them to attend their appointments as normal.'

GP surgeries across the region are open as usual today and patients have been advised to attend appointments unless told otherwise, but clinical commissioning groups (CCGs) have taken to Twitter to warn phone lines are likely to be busy.

A spokesman for all five of Norfolk and Waveny's CCGs said: 'We would like to thank patients for supporting the NHS by using services wisely when they have been under pressure.

'Staff at JPUH have continued to see patients and ensure they receive appropriate care, using well-rehearsed procedures. Most surgery and outpatient appointments are going ahead as normal. Patients have been informed, where possible, if their operation or outpatient appointment has been postponed.

'GP practice computers across Norfolk and Waveney were turned off late Friday afternoon as a precaution. Over the weekend, IT staff have been working to ensure all systems had the required software patch installed before re-starting.

'This may cause systems to be slow in places. Patients are asked to be understanding if this is the case. If you have an appointment you should still attend unless contacted by your surgery and told not to.

'Patients who need urgent medical advice can always call 111 or ask their community pharmacy for advice and over the counter remedies for minor illness or injuries.'

More than 200,000 victims in around 150 countries have been infected by the ransomware which originated in the UK and Spain on Friday before spreading globally.
