The St.Emlyn's choirmaster has asked Iain and Simon to deliver a sermon on the importance of attending the SMACC Chicago conference in May 2015. After their pilgrimages to Australia in 2013 and 2014 they came back enthused and at times rather annoying about how jolly marvellous it all was.
A short podcast on the reasons why it's the little things that matter. Sure, we all love the latest shiny kit, but that's not what always matters and it's not how to move a system to excellence. In this short podcast we talk about why it's good to sweat the small stuff.

A short version from the blog post on balanced sedation on the St.Emlyn's blog. Link here http://stemlynsblog.org/2012/10/balanced-sedation-in-the-ed-st-emlyns/
In summary, if you are going to be good at procedural sedation you need to evaluate the needs of the patient assess their needs and then select the appropriate drugs to tailor their effects to what the patient requires.
This podcast links to the blog post on the main St.Emlyn's website. It's a bit old now but hopefully will help you grasp the basics of sample size calculation. It should be very helpful to anyone considering the critical appraisal component of the FCEM exam.

This is the undertakers trick. If you have arrived here then don't forget to visit the StEmlyns blog as well for more posts on EM topics.
2 caveats about this....I say that I've never cut a ring off. Sort of true as others have done it for me in two circumstances. 1. If there is a deep wound to the finger distal to the ring this is not a great method 2. If the ring did not come off before the injury due to bony (i.e. fixed) enlargement distally then clearly this won't work. However, if they were able to get the ring off that morning, and now they cannot because of soft tissue swelling, and they can tolerate the discomfort of the procedure then this is a great technique.

And obviously, this is best done by someone who knows what they are doing, and you try it at your own risk.
More on basic interpretation of statistics for the critical appraiser. No maths, no formulas, no hard calculations. Just the tools to make the interpretation of results easier.
This week we look at relative risk (RR), absolute risk reduction (ARR) and number needed to treat (NNT). Are they different or the same?
You'll find that NNT is much more useful for the reader, things like relative risk have their place for statisticians and researchers who are seeking to understand their data. However, for clinicians and readers we would be better served by expressing data as NNT (or NNH).
This is not a stats lecture!
What I want to get across is that with very little knowledge you can have a really good go at interpreting the stats in the papers you read. No calculators, no maths, no hard sums, just an appreciation of whether it looks as though the authors did the right sort of thing.
In this podcast we look at different types of data, what p-values are and how do we define confidence intervals.
