1/ A long thread on LifeVest. I promise it will be entertaining. If you find any inaccuracies please let me know.
Paper of VEST published here - will discuss background to WCD and #VEST but not the trial itself nejm.org/doi/full/10.10…

2/ In 2001, FDA gave approval to Lifecor for the first WCD. Later Lifecor was acquired by Zoll (2004 agreement, 2006 acquisition). Zoll maintains a registry for prescribed LifeVests. But lets go back to the FDA approval process.
3/ Lifecor presented 2 separate prospective studies to the FDA; WEARIT and BIROAD. FDA asked for both to be combined into 1 study, and each study representing a subgroup. A total of 289 patients were included.

Check out this amazing pictorial showing the relative flow rates of various intravenous catheters. The numbers represent how long in minutes it takes for each catheter to deliver one liter of saline under 300 mmHg of pressure!

So the catheters are positioned above in order from fastest to slowest going left to right.
Here is a chart listing the catheters from fastest to slowest going top to bottom with their respective infusion times to the second.

These varying catheter flow rates can all be simply explained by Poiseuille's Law:
The flow(Q) of fluid is related to the viscosity(n) of the fluid, the pressure gradient across the tubing(P), and the length(L) and diameter(r) of the tubing.

Hey #medtwitter, it’s time for another #histmed #FOAMed Tweetorial! I’m giving a couple of lectures this fall, and in the spirit of #FOAM I’m going to (try my best) to do a Tweetorial for each, so anyone can benefit/watch me flounder/vehemently disagree with me.
So thank you to @BostonChiefs, and let's talk about semiotics and the development of the physical exam!
First, an opinion poll. Do you think that the physical exam as it is practiced today is useful for care of our patients? When I poll people, I’ve noticed dramatic response differential between training levels.

1/10 – Ventricular Tachycardia
Simplified approach to evaluate tachycardia:
Rule #1 – If HD unstable ➡️ shock!
If HD stable, sit down & think.
Step # 1 - QRS: wide or narrow?
Step # 2 - Rhythm: regular or irregular?
This will narrow DDx!

2/10 - Wide complex tachycardia
Always consider clinical Scenario!
Look for history of MI and cardiomyopathy ➡️ strongly favor #VT!
* If structural heart disease is present, you will be correct 9/10 times with diagnosis of VT!

1. The rota is tough. I know you’re knackered, you’ve probably not seen your friends and family for ages and the rota is playing havoc with your sleep. Please, tell me if you’re struggling. I would rather know, and support you, rather than you burning out. It’s ok not to be ok
2. Don’t lose your humanity
We’re a battle hardened lot, we’re quirky and sometimes cynical. I’m sorry for that. Empathy is something to be treasured, hold onto it. Being kind is never a weakness.

3. Take a break
Thank you, for trying to help me when you’ve been working 8 hours without a break, and you don’t feel able to leave me and the shop floor with a 5 hour wait. You’re amazing. But please, take a break. You’ll be safer, and more productive for it.

Been thinking a bit about what I’ve learnt in the two years since I qualified as a doctor & what (hopefully, helpful and honest) advice I’d give to brand new medics on the cusp of a career in the NHS - a thread #TipsForNewDocs
1. Being a doctor is the best job in the world. Some days it will feel like the worst, but 95% of the time it’s the best and most rewarding career. I adore the NHS. Be proud of yourself, you’ve worked damn hard to get here.
2. Remembering to say “thank you” on a busy ward at 2pm can earn you a cup of tea at 4am. A sincere “thank you” with eye contact might even get you a cup of tea *and* some magical NHS biscuits on your night shift (the holy grail is NHS toast). Nurses are all-seeing superheroes.

Not enough info. History/physical critical. Starting meds ok but get a diagnosis if case not clear cut. Exercise testing is better but not appropriate for every patient. Cath first if you believe unstable/high-risk disease or if symptomatic + high-pretest probability.

Thank you to @rallamee for loaning me the use of her garden and boating lake to do a few demonstrations in this weekend's tweetorial.
Thank you also to a colleague, for sending me this just now. It is enlightening and I am genuinely sorry.

Not all fears are alike.
* Some fears are one-and-done:
I get a cold which progresses to pneumonia. Will I die, or recover?
* Other things hang over us for much longer, perhaps all your life.
Will you get hit by a bus?
Get a heart attack?
There's no "sell by" date on the fear.

All 3 of these are about comparing the scale of dangerousness of one thing AGAINST ANOTHER.
Suppose you are walking through an unfamiliar forest and the road comes to a fork: you have to choose one path.
As you stand, uncertain, a troll pops out of the ground.

Francisomycin, my new natural anti-atherosclerotic antibiotic, has now been published in NEJM to reduce atherosclerosis by 173 arbitrary units (p=0.03).
I am really, really pleased with the result and the fact that I have the patent on this magical stuff.

What does p=0.03 mean?
A. 3% of pts had reduced atherosclerosis?
B. 97% of pts had reduced atherosclerosis?
C. If a drug is ineffective, 3% chance that it produces an effect this extreme.
D. 3% probability that THIS drug is ineffective, i.e. that these results occurred by chance

Thank you to Ali Jazayeri for suggesting this subject on the highly secret DM contact address (@ProfDFrancis).
At first I hesitated over whether this was truly needed amongst such an elite body of scienntific minds as we have reading this thread.
But Pascal Meier insisted that it was.
He said he was watching a whole session dedicated to not understanding this at a conference. Sent a pic!

Like a blog you’ve thrown together at the last minute to maintain you’re public profile, it’s #NHSthisweek :
Protests against the GMC continue, including one suggestion to rip up GMC registration certificates outside their London offices. On a Saturday.
Which leads to the philosophical question, if a man rips up a certificate and no ones there to see it (cos it’s a Saturday) does it make or sound, or even an impact?
It’s Saturday, it’s poorly written, it’s #NHSthisweek:
The health secretary hailed Microsoft Excel with the cells shaded in a threatening red colour as “great technology”
Meanwhile, here at BAM! we too devised a new way of using technology to see the state of the health service in your region
It’s Saturday it’s #NHSthisweek on twitter:
64 emergency medicine doctors write to the PM over the #nhscrisis, meaning 64 bed managers will be angrily demanding to know why the PM hasn’t accepted the referral in 4 hours time...
Meanwhile 64 med regs have been told that they need to chase the result of the letter
