Medicine and Science from The BMJ

The VAERS system in the US monitors adverse events following vaccines, but a new investigation on BMJ.com has found problems with the data mining systems used to spot patterns - and more worryingly, that the agencies involved were alerted about the issues, and didn’t take steps to fix the problem.

David Willman, Pulitzer Prize winning investigative journalist, joins us to explain what he found.

 

Also this week, while the UK parliament still seems divided on assisted dying, in Switzerland it has been allowed for over 80 years - making it an normalised part of medicine. New research has asked patients why they have decided to seek help in ending their lives, and analyses those motivations.  Two authors of this work, Claudia Gamond, a palliative care physician who leads the palliative and supportive care department at the University Hospital in Lausanne, and  Solenne Blanc, a PhD student in sociology, join us to explain what they found.

Something different for the podcast today: a live event. It’s the inaugural BMJ lecture, in partnership with the Academy of Medical Sciences and hosted at the historic Royal Academy of Arts.

We want to talk about the big issues facing healthcare professionals around the world - and we’re starting with one of the biggest: how do we make decisions in the face of real risk and genuine uncertainty?

Well, who better to talk through those big questions than the man who had to try to navigate those risks and uncertainties during the pandemic?

Chris Whitty is England’s Chief Medical Officer and Chief Medical Adviser to the UK Government, advising on all aspects of healthcare. He is also a professor of public health at the London School of Hygiene and Tropical Medicine, where he was director of their Malaria Centre.

In his lecture, Professor Whitty argues that medical training must better prepare doctors to manage risk, highlighting that "higher risk decisions, and accountability for these, have moved to later in training", causing a "substantial and sudden step up" in risk for new consultants. He acknowledges AI’s potential to speed up clinical diagnostics, but warns against public-facing AI tools that present diagnoses with false certainty while ignoring medical risk and uncertainty.

Back in 2024, the BMJ revealed how more than half of the members of the UK government's Scientific Advisory Committee on Nutrition, had declared financial interests with food and drinks companies.

A tightening of the rules followed, but two years after our initial investigation, we have returned - and we found that nearly a third of nutrition advisors still have significant ties to the food industry.

Chris Van Tulleken, professor of infection and immunology at University College London, and author of the book “Ultra Processed People”, joins us to explain why he thinks ongoing industry ties are bad for the UK's health.

 

Also this week. We have tight regulation of medical tech in the UK, but new AI tools don’t fit neatly into that existing process - and so the government has set up a National Commission on the Regulation of AI in Healthcare, 

Alastair Denniston, and Henrietta Hughes, who headed that commission, join us to explain how AI should be monitored, how we can ensure it's safety, and who should be responsible when something goes wrong.

The next few months might be an inflection point for GPs in England and Wales 

Our strong primary care system is often credited in the success of the NHS - But changes to how that system works are currently underway. Legislation is quietly proceeding through parliament that will reorganise the way in which local care is structured, and those changes are raising concerns for GPs.

To talk about how we build a stronger primary care system, and stronger NHS we're joined by:

Victoria Tzortziou Brown, president of the Royal College of General Practitioners

Sam Everington, a GP in East London, and a non-executive director of NHS England

Kamila Hawthorne, GP in South Wales, and chair of National Academy for Social Prescribing

We also take the opportunity to hear about where social prescribing fits into this new picture, and why our panel think it's important in changing the UK's health.

In this week’s podcast we’ll be hearing a lot about exams - the bane of many doctor’s training lives, exams that determine your future are scattered through medicine and can cause a huge amount of anxiety and stress…

 

John McLachlan, professor of medical education at the University of Lancashire, has carried out four reviews of medical exams. He explains what happens to the people who have been marked wrongly, why he thinks re-sits should be done differently, and why multiple choice questions are still in use.

 

Over the Summer there have been extensive protests from the young people of India, the “Cockroach Janta Party” has led demonstrations across the country, sparked by allegations of cheating in India’s “NEET” exams - the federal tests taken by applicants to India's medical training.

 

Rohan Krishnan, orthopaedic surgeon in Delhi, and chief of the Federation of All India Medical Association, and Kathir Karuppiah, a house surgeon in Tamil Nadu, join us to explain where India's medical admissions tests are failing students.

 

We’ll also hear about new research into Chronic Traumatic Encephalopathy in NFL players.  Daniel Daneshvar is associate professor at Harvard Medical School, and he and his co-authors have examined the brains of 338 former players, with the goal of determining how many of them died with CTE neurodegeneration. He joins us to explain his findings, and what it means for competitive sports players and others who play contact sports.
