This is the fourth part in a series on artificial intelligence in medicine and we try and unpick the causes and consequences of adverse events resulting from this technology. Our guest David Lyell is a research fellow at the Australian Institute of Health Innovation (Macquarie University) who has published a first-of-its kind audit of adverse events reported to the US regulator, the Federal Drugs Administration. He breaks down those that were caused by errors in the machine learning algorithm, other aspects of a device or even user error. 
 
We also discuss where these all fit in to the four stages of human information processing, and whether this can inform determinations about liability. Uncertainty around the medicolegal aspects of AI-assisted care is of the main reasons that practitioners report discomfort about the use of this technology. It's a question that hasn’t been well tested yet in the courts, though according to academic lawyer Rita Matulonyte, AI-enhanced devices don’t change the scope of care that has been expected of practitioners in the past.
