The UK has just launched a star-studded National Commission to rewrite the rulebook for AI in the NHS. The goal: faster, safer innovation for patients. It could be a powerful accelerator and will hopefully avoid the pull of becoming another talking shop lost in bureaucracy.

How does an AI model quantify a mistake? It uses a "loss function" – a scorecard that penalises different types of errors. In this episode, we explain what a loss function is, why it's not a one-size-fits-all tool, and how it reveals the true clinical priorities of any AI model. A crucial concept for critically appraising new research.

How does an AI model actually learn to spot disease on a scan? It all comes down to one fundamental goal: minimising error. In this episode, we kick off a new set of episodes on the mechanics of machine learning by explaining this core principle with a simple clinical analogy that will change how you look at AI. Understanding this is the first step to critically appraising any research paper that lands on your desk.

What if an AI could forecast your health like the weather? A groundbreaking new model called Delphi-2M, published in Nature, claims to do just that — predicting your risk for over 1,000 diseases using technology similar to ChatGPT.

But is this the dawn of a new era in preventive medicine, or a high-tech crystal ball that reflects the biases of our current system?

In this week's episode of The Health AI Brief, we put Delphi-2M through a real-world stress test. We break down the impressive science, interrogate its biggest weakness (generalisability), and define the critical next step needed before a tool like this could ever see the light of day in the NHS.

Tune in to find out if this is a future game-changer or a promising idea that's not quite ready for primetime.

We break down a landmark UCL study on the NHS's £21m programme to deploy AI in chest diagnostics.

They uncover the real reasons for significant delays, moving beyond the technology to the critical, real-world barriers: staff capacity, fragmented IT infrastructure, and complex governance. Find out why dedicated project management is the secret to success and what this means for the future of AI in healthcare.

Essential listening for any clinician, manager, or policymaker involved in digital transformation.

Ever been handed a patient's CT scan on a CD-ROM and wondered why medical systems struggle to communicate? The problem is that they need to speak the same language. This episode decodes the three essential standards of medical data exchange.

We break down DICOM (the "courier package" for images), HL7 (the "digital fax machine" for classic hospital data), and FHIR (the modern "smartphone app" enabling a connected future). Understand these acronyms to better appraise AI research and see the path forward for a truly interoperable healthcare system.

How do we know if a medical AI has truly learned to spot disease, or just memorised the answers to its practice questions? The same way we evaluate a trainee: with a final, unseen exam.

This crucial process involves splitting data into three sets: training data (the textbook), validation data (the mock exam), and test data (the final exam). In this episode of The Health AI Brief, we explain why this split is our best defence against overconfident AI, what 'overfitting' means for clinical practice, and why the 'test set' result is the only number you should trust when appraising a new AI study.

How do you teach an AI to read a chest X-ray? The same way a consultant teaches a resident doctor on a ward round: you point, you trace, and you provide the correct answer.

This is data annotation, the meticulous, human-led process of "teaching" an algorithm by labelling thousands of examples. In this episode of The Health AI Brief, we explain why the quality of this digital teaching is everything. Discover why you should always ask who did the labelling when reading a new study, how human disagreement limits AI certainty, and why this is becoming a vital new form of clinical practice.

The headlines were everywhere: a revolutionary AI stethoscope that could more than double the detection of heart failure in GP clinics. The reported results from the TRICORDER trial sound transformative. But what happens when you look beyond the press release?

Was it truly the AI that improved diagnosis, or did the trial simply prompt more testing? With reports that 70% of clinics stopped using the device long-term, what does this mean for real-world feasibility?

A patient's record is a chaotic mix of notes, lab test results, and codes. We can navigate the mess, but how can an AI? The answer lies in data cleaning and preprocessing – the most critical, yet unglamorous, step in building medical AI.

This episode of The Health AI Brief explains why this process is like meticulously preparing ingredients for a complex recipe. We break down the key steps - from handling missing values to standardising formats, and offers three essential takeaways for appraising new AI studies and understanding why a tool that works in one hospital might fail in yours.
