This blog discusses the problem of confirmation bias: our tendency to favour answers that confirm ideas and beliefs that we already have. It also discusses two possible solutions to this problem: 1) referring to systematic reviews, which take account of ALL the available evidence and 2) actively seeking out information which may challenge our preconceptions.
Let’s find out why physicians sometimes contradict each other from a statistical perspective. And see how students can learn from that.
When dealing with a difficult question, we tend to seek the answer for a simpler one, that seems to be relevant. However, a seductive trap awaits us here. Come with me, I’ll show you the world of surrogate endpoints.
Managing hypertension is complex, involves lifestyle modifications such as physical activity and dietary interventions, as well as drugs. Here, we highlight the evidence from Cochrane about which drug is better as a first-line therapy.
According to Scottish arthroplasty project ‘Biennial report 2014’, the number of arthroplasty operations has increased over the past 7 years (7609 hip and 7169 knee arthroplasties were performed in 2013) costing the NHS on average £7000 per patient (Scottish Arthroplasty Project 2014). This blog is a critical appraisal of a study which looked at importance of providing patient-cantered care for your patient right from the initial appointment and the positive effects it can have on patient outcome and cost efficiency.
We hear the word “evidence-based medicine” too often but why is evidence-based medicine important? And what’s the difference between eminence-based medicine? This post addresses those questions and give some examples of both evidence and eminence-based medicine practice.
Cochrane is carrying out some research into the teaching and learning of evidence-based practice in a range of settings, and in particular whether there are barriers to the effective learning about EBP among medical students, junior clinicians, or others. Your answers to this set of questions will help us understand possible future development for use Cochrane in teaching and learning.
Patients, carers and members of the public offer a unique perspective in health and social care research, adding to the expertise of the research team. Improving healthcare services will only be possible by involving the people accessing those services.

Doctors must always ensure they are doing the right thing for each patient. But what are benefits and harms, and how do we ‘balance’ them?
A description of the two types of data analysis – “As Treated” and “Intention to Treat” – using a hypothetical trial as an example
Medically unexplained physical symptoms. The notion of physical symptoms having no medical causes is not an old one; when is it really a Somatoform disorder and what is the best treatment? Two new Cochrane reviews help answer the question.
In this post you are going to figure out how to interpret the evaluation of diagnostic tests through sensitivity and specificity.
Let’s be honest, Evidence-Based Medicine is great. But it’s not perfect. Issues such as the lack of publishing of negative results need to be understood and tackled. In this Youtube video, Prof David Nealy does just that.
