The NHS Practitioner Health Programme - once only for doctors in London, now it’s being rolled out across the NHS to provide the largest, publicly funded, comprehensive physician health service, in the world. However, while helping the individual is essential, systemic change needs to be made to support doctors in our healthcare system. Clare Gerada, GP and medical director of NHS PHP joins us to...

There has been a lot of noise made about calorie counts on labels - the idea being it’s one of those things that might nudge people to make healthier choices. So much so that in 2018, in the USA, it became mandatory for food chains with more than 20 outlets to label the calories in their food. But the effectiveness of that is hard to gauge - it’s relied on reporting from customers, which leads to...

A TB infection can take two forms, active and latent. Active disease is transmissible, and causes the damage to the lungs which makes TB one of the biggest killers in the world. In the latent form, the bacteria Mycobacterium tuberculosis is quiescent and can stay that way for years until it becomes active and causes those clinical signs. Testing for the active version of the disease is done direct...

This week, Dr Arnav Agarwal joins Ray to share the perspective and experiences of a young, recently graduated doctor working in a busy, metropolitan hospital. Despite the long shifts and demanding environment, Arnav makes time and space to reflect on work, life and mortality through his thought-provoking poetry and volunteer work.

This week, Ray ventures into the notoriously complex field of nutrition with special guest, Professor Marion Nestle. Named by Forbes as one of the world's most powerful foodies, Marion’s stellar career spans five decades of research, teaching, advocacy work and the publication of countless prize-winning books.

Statins are now the most commonly used drug in the UK and one of the most commonly used medicines in the world, but debate remains about their use for primary prevention for people without cardiovascular disease. Paula Byrne from the National University of Ireland Galway, joins us to talk about the evidence of benefit for low risk individuals, and what needs to be done to finally answer the questi...

Direct-to-consumer genetic tests are sold online and in shops as a way to “find out what your DNA says". They insights into ancestry or disease risks; others claim to provide information on personality, athletic ability, and child talent. However, interpretation of genetic data is complex and context dependent, and DTC genetic tests may produce false positive and false negative results. Rachel Hor...

Blockchain is the digital technology that underpins cryptocurrencies such as bitcoin, and has been proposed as the digital panacea of our times. But Leeza Osipenko, from the London School of Economics, has thought about how it could actually be used in clinical trials, and what else would need to change in our regulatory environment to make that work.

In quality improvement, measurement is seen as a key driver of change - how well do you know you’re doing, if you can’t actually measure it. So, when something changes in the NHS (say a new guideline) how can you tell how quickly that’s filtering down to the front line. Ben goldacre, from the Nuffield Department of Primary Care Health Sciences at the University of Oxford, joins us to talk about a...

Our latest series kicks off with Australia’s multi-award-winning health and science reporter, Liam Mannix. He joins Ray to share his insights into the role and impact of evidence, advocacy and investigative reporting in today’s ever-changing media landscape.

Talk Evidence is back, with your monthly take on the world of EBM with Duncan Jarvies and GPs Carl Heneghan (also director for the Centre of Evidence Based Medicine at the University of Oxford) and Helen Macdonald (also The BMJ's UK research Editor). This month Carl talks about evidence that restricting your diet might improve health at a population level (1.50) Helen talks about the data on a dro...

After ten years at the helm of the Cochrane Library, Dr David Tovey recently stepped down as Editor-in-Chief.

On the 1st of May, 2018 Scotland was the first country to try a new way of reducing alcohol consumption in its population. It introduced a minimum unit prices for alcohol. Now new research just published on BMJ.com is looking at the effect of that price increase - and measuring how well it has achieved the goal of reducing drinking in Scots. Peter Anderson, professor of alcohol studies at Newcastl...

The BMJ in partnership with The Harvard Global Health Institute has launched a collection of articles exploring how to achieve effective universal health coverage (UHC). The collection highlights the importance of quality in UHC, potential finance models, how best to incentivise stakeholders, and some of the barriers to true UHC. One of those barriers, and it’s a big one, is climate change - patte...

Helen talks about new research on prevention of recurrent VTE - and Carl things the evidence goes further, and we can extend prophylaxis for a year. 13.00 - CRP testing for antibiotic prescription in COPD exacerbations, should we start doing it in primary care settings - and what will that mean. We also hear from Chris Butler, one of the trialists, who explains why being very clear about what you...

Around half of trials that supported new cancer drug approvals in Europe between 2014 and 2016 were judged to be at high risk of bias, in a new study. Huseyin Naci,assistant professor of health policy a the London School of Economics joins us to talk about why potential bias may mean potential exaggeration of treatment effects, and could be costing our health systems a great deal of money. Read th...

This week we saw the release of the much awaited Yellowhammer documents from the government, documents which outline some of the risks involved with Britain’s sudden departure from the EU. The documents themselves outline that there are risks to the supply of medicines - but do not set out the detail of how those risks have been mitigated, and what doctors and patients should do to plan for the po...

This week the Trump administration has banned the sale of flavoured vapes in the USA. The reason for that is the sudden rash of cases of pulmonary disease, including deaths, linked to vaping. The mechanism by which vaping may be causing damage to the lungs is as yet unclear, and our understanding is hampered by the heterogeneous nature of the compounds involved and the mechanisms of delivery. Davi...

In the UK, for just over a year, we've been paying the "Soft Drinks Industry Levy" - a tax on sugary beverages intended to reduce our consumption of free sugars. That was based on taxes that had happened in other countries, however, in the UK high sugar snacks, such as confectionery, cakes, and biscuits make a greater contribution to intakes of free sugars as well as energy than sugar sweetened be...

Brexit. Who knows what’s going to happen in the next few weeks, months, years - the uncertainty is high. In the face of that, you’d hope that the government was doing all it could to plan for any eventuality - let alone for a massive, country altering one like suddenly crashing out without a deal - but Martin McKee, professor of public health at the London School of Hygiene and Tropical Medicine,...

We heard a few podcasts ago about burnout - what it is, and why it should be thought of as a systems issue. Now a project in the Netherlands is trying to investigate who it is that is particularly at risk of burnout, and hopes to test whether individually tailored coaching and counselling can help those who are experiencing the symptoms change the way they’re working. Karel Scheepstra is a psychia...

We know that exercise is good for you - the WHO recommends at least 150 minutes of moderate intensity or 75 minutes of vigorous intensity aerobic physical activity each week. That recommendation is built on evidence that relied on self reporting that may underestimate the amount of lower intensity exercise those people were doing, and at the sometime overestimate the overall amount. That makes new...

Welcome back to Talk Evidence - where Helen Macdonald and Carl Heneghan take you through what's happening in the world of Evidence. This month we'll be discussing tramadol being prescripted postoperatively, and a new EBM verdict says that should change(1.36). How much preventable harm does healthcare causes (11.20. A canadian project to help policy makers get the evidence they need (16.55) One of...

In 2001, Gottfried Hirnschall joined the WHO to work on the global response to HIV/AIDs, 18 years later he just retired as the director of WHO’s department for HIV and Hepatitis. The intervening period, almost half the time we’ve been aware of the disease the fight against the infection has been characterised by scientific breakthroughs, and disappointments - but the people mobilised against the v...

Burnout is a problem in healthcare - it’s a problem for individuals, those who experience it and decide to leave a career they formerly loved, but it’s also a problem for our healthcare system. Burnout is associated with an increase in medical errors, and poor quality of care. Fundamentally it’s a patient safety issue. But, unlike other patient safety issues we tend to think about it, and try to p...
