You have a patient with an anion gap of 30 and bicarbonate of 10 mEq/L. You also determine on VBG that the patient’s pCO2 is 25 mmHg. What trick of the trade can you use to quickly determine whether this low pCO2 is an appropriate compensation of the primary metabolic acidosis? Dr. Jeremy Faust and Dr. Corey Slovis explains the quick “Rule of 15”.
Dr. Rahul Patwari is a one-man statistics teaching machine. In part 4 of this Evidence Based Medicine series, he reviews advance concepts in statistics and calculations including: case-fatality rates, crude mortality rates, specific-mortality rates, years of potential life lost, and direct and indirect age adjustments.
Dr. Jeremy Faust is back with another P-video, which stands for Paucis Videos (paucis means “few” or “brief” in Latin) much like the Paucis Verbis cards. These P-videos are short video-based educational pearls for the practicing physician with a focus on Emergency Medicine and Critical Care. Here Jeremy shares two mnemonics, LUCAS and FEBRILE, to help you remember the common causes for fevers in pediatric and adult patients, respectively.
In part three of this Evidence Based Medicine series, Dr. Rahul Patwari does a deep dive on more advanced concepts in statistics. Specifically, he reviews: odds, incidence, prevalence, and incidence rates. What IS the difference between incidence and prevalence? Ever wonder?
In part 2 of this Evidence Based Medicine series by Dr. Rahul Patwari, more advanced statistical concepts are reviewed. These concepts include ROC curves, screening tests, probability (multiplication and addition rules) and the binomial theorem. Sounds daunting but these short videos really condenses the concepts into digestible lessons.
Across the medical profession, an essential skill is to be able to understand and interpret original research publications to guide your evidence-based practices. Dr. Rahul Patwari reviews the basics of statistics, specifically sensitivity and specificity, predictive values, probability, and the tradeoff between sensitivity and specificity.
Over the past 4+ years, ALiEM has grown to be an exciting educational blog which focuses on the clinical, educational, and academic aspects of emergency medicine. It has far exceeded any of my expectations and has been an incredibly valuable and rewarding experience for me personally. Since its inception, the site has transitioned from a single-author site to a site with a superstar team of authors who cover a diverse range of clinical (e.g. cardiovascular, critical care, geriatric EM, pharmacology) and educational (book club, MEdiC series, educational pedagogies) content as well as an expert peer-review system. As now the blog’s Editor in Chief, I am constantly amazed that we have been successful on pretty much a small, self-funded budget. Going forward, I now realize that the blog’s continued growth and creative strategies are rate-limited by funding.
