Leading Healthcare Researcher: Is this Australia's Biggest Hidden Health Risk?

Pathology touches every single one of us, yet most people have no idea what happens after their blood is drawn or sample is taken. Dr Caitlin Keighley is a pathologist, microbiologist, CEO, researcher, and mum. She runs the only pathology business outside Australia's capital cities and works at the cutting edge of science and healthcare, where diagnosis and decision making can literally change lives every day. With over 90 published research articles, a PhD in fungal infections, and a passion for regional health, Caitlin is sharp, curious, and deeply committed to solving problems that matter. She leads a team that processes samples from over 90 collection centres, maintains an error rate of less than 1 in 10,000, and has pioneered innovations like text message result delivery that helped flatten the flu season. In this episode, she reveals the hidden world of pathology, the power of diagnostic certainty, and why knowing versus thinking changes everything. She explains: - How 30 people touch every single test result before it reaches a patient - Why fungal bloodstream infections still have a 30 to 50 percent mortality rate after 20 years - The psychological impact of knowing versus thinking you have a virus and how it changes behaviour - How text messaging flu results helped stop what looked like a massive flu season in its tracks - Why antibiotic resistance goes up every winter but also comes back down and what that means for the future - The shocking fact that pathology funding hasn't been indexed in over 20 years - Why Australia's pathology quality standards are among the highest in the world - How AI and machine learning are already integrated into pathology in ways most people don't realise - What it takes to build a culture where quality is in the DNA and trust is the foundation **0:00 - Introduction: Who is Dr Caitlin Keighley?** Background, career journey, and what drives her passion for pathology and infectious diseases. **05:00 - Growing Up and Deciding on Medicine** How a neighbour's PhD sparked a lifelong fascination with infections and the immune system. **08:30 - Medical Training and the Path to Pathology** Melbourne, Alice Springs, and the moment regional health became her focus. **12:00 - The Eye-Opening Reality of Regional Healthcare** Why Alice Springs and Lajamanu were more confronting than working in Cameroon. **16:00 - Training as a Physician and Pathologist** What dual training really means and why it takes 16 years from finishing school to becoming a specialist. **20:00 - Why Fungi?
