Iona Heath
EPISODE 15: Iona Heath

Long-time London GP

This week a very different kind of conversation on the Recommended Dose – one that considers the art of medicine more than the science. Iona Heath is a long-time family doctor who has worked in a London GP clinic for over 30 years, and at one time became President of the Royal College of General Practitioners. With an international profile, gained in part through her much-loved writing in the BMJ, Iona is unlike many of our previous guests. For a start, she loves words more than numbers, and literature more than clinical guidelines. Host Ray Moynihan caught up with Iona at a recent conference in Helsinki – where she'd just presented little data but much food for thought from the likes of novelists EM Forster and James Baldwin. Here, she shares more of her love of literature and thoughtful commitment to the best kind of patient care.

Gordon Guyatt
EPISODE 14: Gordon Guyatt

Godfather of Evidence Based Medicine

This week Ray sits down with the man best known as the godfather of Evidence Based Medicine (or EBM), Professor Gordon Guyatt. Together they explore the past, present and future of EBM, and look at how an approach encouraging doctors to look more rigorously at the evidence grew into a global reform movement to better inform all our healthcare decisions.

Like most global movements, EBM is not without its critics. Acknowledging this, Gordon shares his thoughts on prominent critiques that argue EBM has been 'hijacked' by commercial interests. And on a more personal note, he reflects on his early dreams of being a novelist, his four tilts at election to Canada's Parliament, and the many ways his two very different parents have shaped his world view.

Iain Chalmers

Founder, Cochrane Collaboration & James Lind Alliance

This week, a very special conversation with a maverick British medico who set up a tiny research centre in Oxford and watched it grow into a global collaboration of over 40,000 people across 130 countries. Three decades on, the Cochrane Collaboration now produces the world's most trusted health evidence that is used by patients, health professionals, researchers and policy makers around the world every day.

Cochrane co-founder Iain Chalmers joins Ray to look back on the origins of the organisation and the extraordinary life of its namesake, Archie Cochrane. Iain also reflects on his work beyond the collaboration - from working in refugee camps in Gaza to teaching children in Uganda how to detect ‘bullshit’ health claims and more recently, establishing the James Lind Alliance. It's no surprise he's received the BMJ’s most prestigious award for a lifetime of achievement in healthcare, along with a knighthood from the Queen.

Alex Barratt

Professor of Public Health, The University of Sydney

This week’s guest has led something of a double life, using both medicine and the media to explore and promote the critical role of evidence in healthcare. Now based at the University of Sydney, Alexandra Barratt's journey from clinician to journalist to global advocate for evidence based medicine and shared decision-making is a fascinating one. 

Here she talks with Ray about her varied career and the reasons she's ended up challenging conventional wisdom. She also talks about her research into the pros and cons of breast cancer screening and questions the widely-accepted idea that early detection is always the best medicine.

Producer and presenter of ABC RN's Health Report

A familiar voice to millions, Dr Norman Swan is Australia’s best known health reporter. Having presented the ABC’s Health Report for more than three decades, this week he’s on the other side of the microphone.

John Ioannidis

Professor of Medicine and of Health Research and Policy at Stanford University

Series two of The Recommended Dose kicks off with polymath and poet, Dr John Ioannidis. Recognised by The Atlantic as one the most influential scientists alive today, he’s a global authority on genetics, medical research and the nature of scientific inquiry itself – among many other things.

A professor at Stanford University, John has authored close to 1,000 academic papers and served on the editorial boards of 30 of the world's top journals. He is best known for seriously challenging the status quo. His trailblazing 2005 paper Why Most Published Research Findings Are False has been viewed over 2.5 million times and is the most cited article in the history of PLoS Medicine. In it, he argues that much medical research is biased, overblown or simply wrong. Here, he talks to Ray about the far-reaching implications of these findings for people both inside and outside the world of health.

While most closely associated with exploring cutting-edge conundrums across science, genomics and even economics, John is also something of a humanist. He’d be right at home with the philosophers of ancient Greece, seeking as he does to find answers to the big questions of the day in science and medicine, as well as in nature and narratives. 

A voracious reader himself, John has a lifelong love of ‘swimming in books’ and has penned seven literary works of his own in Greek – two of which have been nominated for prestigious literary prizes. And fittingly, he finds inspiration for his myriad of multi-disciplinary pursuits on Antipaxi, one of Greece’s most beautiful and secluded islands. 

He shares some of his distinctive logic, reason - and even a little of his poetry - on this very special episode of The Recommended Dose.

Acclaimed British novelist

Hailed as one of the best British novelists writing today, Sarah Moss is our very special literary guest on TRD this week.

The role of the writer, Sarah says, is to ‘ask hard questions beautifully’. Here she talks to Ray about the research and reflection that goes into illuminating both historical and contemporary medical worlds that raise critical questions about the way we live today.

Prathap Tharyan

Psychiatrist and Director of Cochrane South Asia

Psychiatrist and would-be international DJ Prathap Tharyan joins Ray from his home in India this week to explore a fascinating fraction of his work, life and philosophy. His work with people in the midst of humanitarian crises has consistently shown that good intentions are no substitute for good evidence.

Prathap’s wide-ranging agenda reflects a decidedly down-to-earth and original take on understanding and improving the human condition. Be it tending to victims of the Boxing Day tsunami, ensuring humanistic care for the homeless or working with Wikipedia to get better health information to millions around the globe.

Paul Glasziou

Professor of Evidence Based Medicine, Bond University

He explores big picture health issues like overdiagnosis, overtreatment and the implications of genomic testing, alongside important questions for our everyday health - like how you can find and use evidence and put it to good use when visiting or choosing your own doctor or specialist.

Ray braves a chilly Gold Coast beach at the crack of dawn to find Paul and his close colleague/best surfing buddy Professor Chris Del Mar catching waves, spotting whales and agreeing that fun is actually a surprisingly essential part of serious research work.
