Artificial intelligence can predict people’s health problems over a decade into the future, say scientists.<\/p>\n
The technology has learned to spot patterns in people’s medical records to calculate their risk of more than 1,000 diseases.<\/p>\n
The researchers say it is like a weather forecast that anticipates a 70% chance of rain \u2013 but for human health.<\/p>\n
Their vision is to use the AI model to spot high-risk patients to prevent disease and to help hospitals understand demand in their area, years ahead of time.<\/p>\n
The model \u2013 called Delphi-2M – uses similar technology to well-known AI chatbots like ChatGPT.<\/p>\n
AI chatbots are trained to understand patterns of language so they can predict the sequence of words in a sentence.<\/p>\n
Delphi-2M has been trained to find patterns in anonymous medical records so it can predict what comes next and when.<\/p>\n
It doesn’t predict exact dates, like a heart attack on October 1, but instead estimates the likelihood of 1,231 diseases.<\/p>\n
\u00ab\u00a0So, just like weather, where we could have a 70% chance of rain, we can do that for healthcare,\u00a0\u00bb Prof Ewan Birney, the interim executive director of the European Molecular Biology Laboratory, told me.<\/p>\n
\u00ab\u00a0And we can do that not just for one disease, but all diseases at the same time – we’ve never been able to do that before. I’m excited,\u00a0\u00bb he said.<\/p>\n
The AI model was initially developed using anonymous UK data – including hospital admissions, GP records and lifestyle habits such as smoking – collected from more than 400,000 people as part of the UK Biobank research project.<\/p>\n
The model was then tested to see if its predictions stacked up using data from other Biobank participants, and then with 1.9 million people’s medical records in Denmark.<\/p>\n
\u00ab\u00a0It’s good, it’s really good in Denmark,\u00a0\u00bb says Prof Birney.<\/p>\n
\u00ab\u00a0If our model says it’s a one-in-10 risk for the next year, it really does seem like it turns out to be one in 10.\u00a0\u00bb<\/p>\n
The model is best at predicting diseases like type 2 diabetes, heart attacks and sepsis that have a clear disease progression, rather than more random events like infections.<\/p>\n
People are already offered a cholesterol-lowering statin based on a calculation of their risk of a heart attack or stroke.<\/p>\n
The AI tool is not ready for clinical use, but the plan is to use it in a similar way, to spot high-risk patients while there is an opportunity to intervene early and prevent disease.<\/p>\n
This could include medicines or specific lifestyle advice – such as people likely to develop some liver disorders benefitting from cutting back their alcohol intake more than the general population.<\/p>\n
The artificial intelligence could also help inform disease-screening programmes and analyse all the healthcare records in an area to anticipate demand – such as how many heart attacks a year there will be in Norwich in 2030, to help plan resources.<\/p>\n
\u00ab\u00a0This is the beginning of a new way to understand human health and disease progression,\u00a0\u00bb said Prof Moritz Gerstung, head of the division of AI in oncology at DKFZ, the German Cancer Research Centre.<\/p>\n
He added: \u00ab\u00a0Generative models such as ours could one day help personalise care and anticipate healthcare needs at scale.\u00a0\u00bb<\/p>\n
The AI model, described in the scientific journal Nature, needs refining and testing before it is used clinically.<\/p>\n
There are also potential biases as it was built from UK Biobank data which is drawn mostly from people aged 40 to 70, rather than the whole population.<\/p>\n
The model is now being upgraded to account for more medical data such as imaging, genetics and blood analysis.<\/p>\n
But Prof Birney says: \u00ab\u00a0Just to stress, this is research \u2013 everything needs to be tested and well-regulated and thought about before it’s used, but the technology is here to make these kinds of predictions.\u00a0\u00bb<\/p>\n
He anticipates it will follow a similar path to the use of genomics in healthcare where it took a decade to go from scientists being confident in the technology to healthcare being able to use it routinely.<\/p>\n
The study was a collaboration between the European Molecular Biology Laboratory, the German Cancer Research Centre (DKFZ) and the University of Copenhagen.<\/p>\n
Prof Gustavo Sudre, a neuroimaging and AI researcher at King’s College London, commented: \u00ab\u00a0This research looks to be a significant step towards scalable, interpretable, and \u2013 most importantly \u2013 ethically responsible form of predictive modelling in medicine.\u00a0\u00bb<\/p>\n","protected":false},"excerpt":{"rendered":"
