Artificial Intelligence in Medicine

NHS Hot Topics_ AI

Artificial Intelligence (AI) is “the ability of a computer or other machine to perform actions thought to require intelligence. Among these actions are logical deduction and inference, creativity, the ability to make decisions based on past experience or insufficient or conflicting information, and the ability to understand spoken language.” So – how can artificial intelligence in medicine be used?

AI is therefore an umbrella term for a computer being able to make decisions. The way in which ‘it’ does this, how it gathers data, interprets and produces an output, are brought about in different ways.

Many systems we use today use technology supported by AI infrastructures, which often go unnoticed. Amazon’s Alexa is an example. The computer recognises spoken word and is able to respond. Yet, the (potential) uses of AI in medicine have far greater applications than this.

How could Artificial Intelligence in Medicine be used?

A great deal of diagnosis is about recognising patterns. For example, radiologists will look at x-ray images to spot potential disease. However, if we spotted more subtle patterns earlier, perhaps the disease could have been diagnosed at an earlier stage.

This is where artificial intelligence in medicine can be useful. Computers can be programmed to read data. Using algorithms, very subtle changes can be detected, either as the precursor of a disease or before it has propagated.  

The benefits to the NHS were published by in their document ‘thinking on its own: AI in the NHS’, which states: “AI could support the delivery of the NHS’s Five Year Forward View, which aims to narrow three gaps in health provision.

AI could help address the health and wellbeing gap by predicting which individuals or groups of individuals are at risk of illness and allow the NHS to target treatment more effectively towards them.”

However, it’s not as easy as it all sounds. Data collection in general is under huge. As a result, the public are wary about how their data is used, especially the levels of personal information required.

The government aims to make the NHS a world-leader in healthcare innovation and recognises the importance of AI. Whilst there are significant costs of developing these systems, there are often projected savings in the long run. When we consider the current state of the NHS and the problems it faces, it seems that AI systems have come at the perfect time.

How is artificial intelligence in medicine being used already?

There are several examples of how artificial intelligence in medicine is being adopted both in the UK and internationally already:
