    The ChatGPT Health controversy: what the viral Nature Medicine study missed with David Fraile Navarro

    Welcome to Pulse: Amplify, where we sit down with the leaders and changemakers shaping the future of health.  A recent Nature Medicine study went viral after reporting that ChatGPT Health under-triaged more than half of emergency cases when tested using clinician-written scenarios. The finding raised serious concerns about whether consumer AI tools are safe for medical triage. But researchers from Macquarie University’s Australian Institute of Health Innovation took a closer look at the study design and suspected the results might reflect the evaluation format rather than the AI’s clinical capability. In this episode of Pulse Amplify, Louise and George speak with David Fraile Navarro about their follow-up study testing five frontier AI models across more than a thousand trials. Their research suggests that when AI systems are evaluated using more natural, patient-style interactions rather than exam-style prompts, triage performance improves significantly. The discussion explores why prompt structure, forced answer formats, and restrictions on clarifying questions can dramatically alter model behaviour, and why designing realistic evaluation methods is essential as millions of people begin using AI for health advice. The conversation also examines broader questions: How should AI triage tools be evaluated? What role should clinicians play in AI-mediated care? And what do patients need to know before trusting AI with health decisions?

    The Eucalyptus Exit, an AI Hackathon Cardiologist, and Why Good Tech Still Fails

    This week on Pulse: Hot Topics, Louise and George break down… One of the biggest exits in Australian digital health history sees Sydney-founded telehealth company Eucalyptus acquired by U.S. platform Hims & Hers in a deal worth up to $1.6 billion, raising questions about the rise of global consumer health infrastructure and what it means for the future of care delivery.  A cardiologist in Brussels places third in Anthropic’s global Claude AI hackathon after building a patient follow-up tool in just seven days, highlighting how domain expertise combined with generative AI tools could dramatically accelerate healthcare innovation.  A massive NHS trial of an AI-enabled “tricorder-style” stethoscope shows the technology can dramatically improve detection of heart failure and atrial fibrillation — but poor workflow integration meant many clinicians simply stopped using it.  Finally, a curious new study finds emojis appearing in electronic health records, prompting a light-hearted but serious discussion about clinical documentation standards, data quality and what happens when modern communication habits collide with medical records. We are on tour! Charlotte Blease of #DrBot book fame and Louise are hitting the road together. The Sydney event was fantastic, it’s not too late to catch the Melbourne book launch.

    Jordi Piera Jimenez on Interoperability Theatre and Building Digital Health on Stone, Not Sand

    Welcome to Pulse: Amplify, where we sit down with the leaders and changemakers shaping the future of health.  Jordi Piera Jiménez joins Pulse to unpack the foundations of digital health. Fresh from stepping down as Director of Digital Health Strategy at the Catalan Health Service, Jordi reflects on what most health systems are still getting wrong: interoperability that’s more theatre than reality, AI built on poorly structured clinical data, and the dangerous confusion of digital transformation with IT procurement. We explore why public health systems should own their digital infrastructure, how procurement can be a powerful lever for change, and why clinicians must be better supported to understand that documentation is the core of modern healthcare. Jordi shares a bold vision for the next decade: true digital public infrastructure, genuine patient agency over data, and platform economies that drive innovation without vendor lock-in. A thoughtful, systems-level conversation about infrastructure, governance, ethics — and getting the foundations right.

    Two AI Healthcare Futures? Australia Builds Medicine Infrastructure and China Scales GenAI to Billions

    This week on Pulse: Hot Topics, Louise and George tackle big shifts in medicines safety and the accelerating global AI race in healthcare. Australia moves toward a National Medicines Record The Federal Government announces reforms requiring medicines prescribed via online platforms to be uploaded to My Health Record — including clinical context. With medication-related harm accounting for around 250,000 hospital admissions annually, is this the safety infrastructure Australia has needed for decades? AI predicts 130 diseases from one night of sleep A new Nature Medicine study claims a sleep foundation model trained on 585,000 hours of data can predict future risk of more than 130 diseases. Breakthrough preventative medicine — or promising science with important caveats. China’s AI healthcare surge China’s Ant Group health chatbot reaches 30 million monthly users, embedded inside Alipay’s super-app ecosystem. Meanwhile, China announces a $2–3 billion national AI healthcare strategy targeting population-scale deployment by 2030. Are we witnessing two divergent AI healthcare futures — cautious and regulated versus centralised and scaled? We are on tour!
