AI-assisted healthcare is reaching maturity in many applications and could alleviate some of the capacity gap increasingly faced by health systems . Over the next three podcasts we focus on artificial intelligence tools designed to assist directly with clinical practice. Most commonly reported on are the algorithms capable of pattern recognition on medical images, that in some settings perform as well or better than expert diagnosticians at classifying disease. AI models have also been developed to perform regression analyses more complex than classical risk stratification aids.The standard statistical algorithms used to solve these problems struggle when many variables are introduced, in which case deep learning models that mimic brain networks are sometimes a powerful alternative. In this episode we explain how machine learning algorithms are trained on particular tasks and where there are risks of error and bias being introduced. In part 2, we identify the ergonomic issues that affect practical implementation of AI tools in the clinic and in the decision cascade. And in the final episode of the series we discuss the questions that regulators and lawyers should be asking of this new technology and what role natural language processors might have in medicine.
