How can a 99% accurate medical test give you a 9% chance of having the disease if it comes back positive? 🤔 If you are in medicine this is the SINGLE most important diagnostic testing concept to know. Welcome to the difference between specificity and positive predictive value. Sensitivity & specificity are fixed test properties. These do not factor how common a disease is (prevalence) Positive Predictive Value (probability a positive test reflects having a disease) factors in prevalence and is actually more important to clinicians than sens/spec. It is harder to figure out though because we need to have a gestault for how prevalent a disease is for the EXACT patient we are seeing. If you have very low prevalence, even with a great test, most positives are false positives. This is why screening low-risk patients can result in many false positives and harm To master this, just play with the calculator yourself and you will see!!!!👇

Learning hemodynamics is hard. I created a simulator that let's you titrate vasopressors, inotropes, vasodilators, and fluids across different hemodynamic states. How can I make this even more realistic? Still some hemodynamics responses to optimize. Try it and let me know👇

Version 2 of our ShockCalcs hemodynamics simulator is live. I've refined the physiology a ton, added new meds, and also a real-time Frank Starling curve that responds to fluids + vasopressors. Check it out (link in reply), and reply here with feedback on how to improve further!

Excited to share our tool Resub that automatically formats your manuscript for any journal. We designed Resub for clinical researchers who: 1) Hate wasting time formatting papers 2) Want to save hours per manuscript 3) Are committed to productivity and impact You can trial it for free at Appreciate the repost and you sharing with any researchers you know 🙏

(1/3) The hemodynamic interfaces paradigm proposed by Philippe Rola et al. is probably the most comprehensive paradigm for assessing shock. Not going to lie, its a bit complicated. I comprehensive calculator with theory and practice tips to help you understand the interfaces as part of a NEW project ShockCalcs👇

(1/3) Blakemore insertions for variceal bleeds might seem daunting but typically are straightforward.. Until they aren't. This is the BEST trick I have seen for challenging Blakemore insertions. Use a bougie to help make the tip of the Blakemore more rigid in the posterior oropharynx. This was filmed at a workshop for the #HR2023 conference - come hang out with us again in May 2025 (registration in thread) Here are some more Blakemore tips 🧵

Would anyone actually play this ICU simulation mini-game I created if I polish it up a bit? The premise is you are looking after an ICU. Pages start coming in and you have to keep up by answering the scenarios correct... otherwise, coded!
