Supercomputers which can analyse blood samples and predict which patients are likely to become seriously ill could save tens of thousands of lives a year, it was revealed last night, according to The Daily Express.
The artificial intelligence (AI) system, developed at University College London and set to be piloted in NHS hospitals later this year, will screen “at risk” patients so doctors can take early action to prevent death or serious illness. Prof Young, a consultant surgeon at Southend University Hospital, said: “I am so excited about this form of technology. ”Instead of people getting sick or dying because they are not picked up in time, this will allow us to step in earlier which will save lives and an enormous amount of money. “I think the potential of AI in healthcare like this is as big as the Industrial Revolution was — and signals a completely new example in the way we manage healthcare. ”
The technology is the brainchild of Dr Vishal Nangalia, a consultant at the Royal Free Hospital in London. He used AI to analyse a billion stored blood samples from 20 different UK hospital trusts dating back up to 12 years. Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.
He found the technique forecast outcomes of patients with kidney problems with up to 95 percent accuracy. Traditional methods highlighting serious patient concerns picked up as few as 16 percent of patients who went on to die. “This gives us the opportunity not only to save lives but to prevent serious illness, making the health service not only safer but more efficient. ” Prof Young said, “Instead of waiting for people to get worse, we will be able to treat them earlier. ”
