PATIENTS should wear “diet tracking apps” to monitor their health after ops, Health Secretary Matt Hancock said last night.

Launching more details about his hopes for a technological revolution, Mr Hancock said NHS trusts would also be forced to use systems that “talk to each other” to stop patients getting “suboptimal care”.

In a document setting out his vision, he said those with long-term conditions should have access to online apps to meet their needs.

He said current technology systems across the health and care sectors “don’t talk to each other, fail frequently and do not follow modern cyber security practices”.

The report said: “As a result, some people are getting suboptimal care, staff are frustrated and money could be saved and released for the front line.”

It said the potential of using cutting-edge technologies to support preventative, predictive and personalised care would “transform” health and social care in this country.

Digital services and IT systems in the NHS will have to meet a clear set of mandatory standards to ensure they can “talk to each other” and can be replaced when better technologies are created.

Outside of these standards, local health bodies will have the freedom to buy what they need.

Officials said any system which does not meet these standards will be phased out.

Launching his vision, Mr Hancock said: “The tech revolution is coming to the NHS.

“These robust standards will ensure that every part of the NHS can use the best technology to improve patient safety, reduce delays and speed up appointments.

“A modern technical architecture for the health and care service has huge potential to deliver better services and to unlock our innovations.

“We want this approach to empower the country’s best innovators - inside and outside the NHS - and we want to hear from staff, experts and suppliers to ensure our standards will deliver the most advanced health and care service in the world.”
