This week’s guest on The Recommended Dose 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.

She joins host Ray Moynihan to share her thoughs on 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.
