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 our listeners thinks "Simple" GPs are anything but (28.30) - and we'll be asking Alexa about our health queries.

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 virus have changed the way the world funds global health, the way patients are included in research agendas, and saved lives. Gottfried spoke to us during his post retirement holiday in France, and talked about his experiences, and what the legacy of HIV/AIDs will be.

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 prevent it, at an individual not systems level. However, Anthony Montgomery from the University of Macedonia, and Christina Maslach, from the University of California, Berkeley, urge us to start treating burnout as a systems issue. We hear about how we can spot burnout, and what can be done to try and mitigate it.

The UK has just seen it’s hottest July on record, including the highest ever temperature recorded. With climate change in the forefront of our minds, it’s timely that we have two editorials on the sustainability and health. Michael Depledge, emeritus professor of environment and human health at University of Exeter Medical School, and author of the editorial Time and Tide, explains how closely the oceans and seas are linked to human health. Also Gillian Leng, deputy chief executive and director of health and social care at NICE has ideas about what the NHS can do to become more sustainable, and how we could evaluate the impact treatments have on the planet.

At EBM live recently, we ran a workshop with researchers, patients and clinicians to talk about patient rights in research - should patients be setting the full research agenda? Should they be full participants and authors? Helen Macdonald, BMJ’s UK research editor and co-host of our talk evidence podcast sat down to Paul Wicks, researcher and patient, and Emma Cartwright, The BMJ's What your patient is thinking editor, to reflect on what the workshop uncovered - and where we should be moving to next.

Cannabinoid hyperemesis syndrome is a relatively newly recognised condition - but, according to one study, can account for up to 6% of patients presenting to emergency departments. The causal mechanism is as yet unclear - but currently the only known way to prevent the syndrome is for the patient to stop their cannabis use. Yaniv Chocron, chief resident at Lausanne University Hospital, Lausanne, Switzerland talks us through spotting the condition, and what we think might be the mechanism of action.

Cochrane Austria have been asking the public what they'd like to know about health. Not whether the latest drug is more efficacious, but whether glacier stone power cures hangovers. Gerald Gartlehner, director of the Cochrane Austria Centre joins us to explain what they do, and how their evidence has been received.

Fertility awareness based methods of contraception are increasingly being used for pregnancy prevention. In the US, the proportion of contraceptive users who choose such methods has grown from 1% in 2008 to approximately 3% in 2014.  Relative to other methods of pregnancy prevention, however, substantial misinformation exists around fertility awareness based methods of contraception, particularly about the effectiveness of specific methods and how to use them.  Rachel Urrutia, assistant professor of Obstetrics and Gynecology at the, University of North Carolina,  and Chelsea Polis, senior research scientist at the Guttmacher Institute join us to describe the various fertility awareness based methods, and the evidence base behind all the options available.

This month we have some more feedback from our listeners (2.20) Carl says it's time to start smoking cessation (or stop the reduction in funding for smoking reduction) (11.40) and marvels at how pretty Richard Doll's seminal smoking paper is. It's gloves off for infection control (22.20) Andrew George, a non-executive director of the Health Research Authority joins us to talk about their consultation on research transparency, and explains how you can get involved (27.04) And we talk about a new tool for rating the transparency of pharma companies (37.40) Reading list: Impact of the WHO Framework Convention on Tobacco Control on global cigarette consumption https://www.bmj.com/content/365/bmj.l2287 Sixty seconds on . . . gloves off https://www.bmj.com/content/366/bmj.l4498 HRA transparency consultation https://www.hra.nhs.uk/about-us/consultations/make-it-public/our-vision-research-transparency/ Sharing of clinical trial data and results reporting practices among large pharmaceutical companies https://www.bmj.com/content/366/bmj.l4217

Margaret Heffernan has thought a lot about whistleblowing, and why companies don't respond well to it. She wrote the "Book Wilful Blindness: Why We Ignore the Obvious at our Peril". In this podcast she talks about how culture, and groupthink, leads to a culture where whistleblowers are ignored, and why the NHS needs to change the way it treats people who try and call out poor care. This was recorded at Risky Business - https://www.riskybusiness.events/ where you can find our more about the conference and watch previous talks.
