Evidence-based thinking and why it matters
Views expressed may represent the views of the author and not necessarily those of CEBM as a group

Seeing is believing. Or is it?

Observation has been the principle of empirical scientific method since Aristotle, who viewed scientific inquiry as ‘…progression from observations to general principles and back to observations’.

Practice of EBHC – what to expect

Its a busy week, although you will definitely not just sit and listen to talks all day: all the sessions are interactive and we utilise group work sessions. Everyone brings their expertise and perspectives to the group, which always makes for interesting discussions.

Bias is good

How studying the history and philosophy of EBM helps

There were about 20,000 POWs in the camp, of whom a quarter were British. The diet was about 600 calories a day and we all had diarrhoea. In addition we had severe epidemics of typhoid, diphtheria, infections, jaundice, and sand-fly fever…

Those that can...teach (EBP)

My favourite EBP course of the year (every year!) For me, as a tutor, it is probably one of my favourite teaching roles throughout the academic year.

A new generation of bias in EBM

In the EUROPA trial 12,218 patients were randomized to receive perindopril or placebo. 9.9% of the participants in the ‘placebo’ group died or had a heart attack, whereas only 8% in the experimental group died or had a heart attack: roughly a 2% absolute effect size. You would have to treat 50 patients with the drug to get one with a positive outcome.

Cutting my wisdom teeth

“A man begins cutting his teeth the first time he bites off more than he can chew” Herb Caen
This was very much my experience when teaching about ’Study Designs’ on day one of the Practice of Evidence Based Health Care. Active, enthusiastic and engaged audiences, in my opinion, always make for a better teaching (and hopefully learning) experience.

A summary: Knowledge into Action

Everywhere we look, there seem to be problems in synthesising and organising knowledge for use. We know that the latest research evidence is not routinely implemented and that at times, we don’t change practice to prevent harm.
