Welcome back to Talk Evidence, your monthly roundup of the world of EBM. And I'm staging a little takeover this week. We're not doing the usual start, stop or anything. We're going to talk about coronavirus because I live in Brighton, which if you're outside the UK, you might not know, but seems to be the epicentre of coronavirus infection in the UK. We have doctor surgeries shut. We have schools being shut. We have people being quarantined. So I want to know what is the evidence about how this is spreading, what the virus is and maybe treatment as well. As always, I'm joined by our two favourite EBM nerds. We've got Carl Hennigan and Helen MacDonald. Carl, can I get you to introduce yourself?
Yes, hi, I am Editor-in-Chief of BMJ Evidence-Based Medicine, Professor of EBM at the University of Oxford and a GP.
And Helen, you're joining us from Bath.
Yes, hi, I am Editor-in-Chief of BMJ Evidence-Based Medicine, Professor of EBM at the University of Oxford and a GP.
And Helen, you're joining us from Bath today because you are isolated but not with coronavirus. It's chickenpox. Can I get you to introduce yourself?
Yes, I'm Helen MacDonald, the UK research editor for the BMJ.
If we think about coronavirus from our nerdy EBM point of view, this is a really interesting time. This is a brand new virus that we don't know anything about, really. And so that evidence kind of ecosystem we talk about is just evolving at this point.
I agree. This is a very interesting time in the world of evidence-based medicine. As we're going to hear on the programme, you're going to have evidence from case reports. You're going to have evidence from a Cochrane review with case control studies and cohort studies, what we call low-quality evidence. We're going to hear about rapid reviews of evidence. We're going to look at model reproduction numbers, epidemiology of infection and case fatality rates, and all about how to do randomised trials and what's needed in things like hand-watching. The whole array of evidence, which... is interesting and helps us think about this important public health issue right now, coronavirus.
This might be the one time we hear Carl Heineken telling us to go and read a case report in the NEJM.
Well, not only that, what's really interesting, and this is important, in pandemics, there's a real need to make this stuff available rapidly and to make it open access so people can actually use it and read it and interpret it in what is a fast-moving emerging infection.
And Helen, what kind of evidence are you particularly interested in, in this emerging world?
I think I'm most interested in just thinking about having a totally blank page that we really knew nothing about this virus, about how it transmits, about what symptoms people have, about how to prevent it, about how to treat it. It seems like we didn't know anything a couple of months ago. And I'd be really interested to hear from an infectious disease epidemiologist about how you begin to piece together all of these emerging pieces of evidence into a picture.
So we've heard from some interesting people from Imperial. We've got Peter Openshaw, who's a professor of experimental medicine. Wendy Barclay, who's head of the Department of Infectious Diseases there. And Reena McIntyre is a professor of infectious diseases and epidemiology down in Sydney. We're going to go through some things around, as Carl said, prevention issues. about what is this virus, some things we might do to prevent spread, and then if that's not so effective, what do we know about treatment? But before all of that, I suppose we should get an overview from an expert who knows.
I'm Raina McIntyre. I'm Professor of Global Biosecurity at the Kirby Institute, University of New South Wales, Australia. I study infectious diseases, particularly emerging infectious diseases, vaccine preventable diseases and issues around biosecurity, pandemic preparedness. It is really important to get a good evidence base for a number of different parameters around COVID-19.
