Paucis Verbis: Overanticoagulation and supratherapeutic INR

I find it amazing that I know more non-emergency physicians virtually in the social media world rather than in person. Primarily through Twitter, I follow and am followed by medical educators from various specialties. If you haven’t joined Twitter yet, I think it might be time. There is a whole world of collaboration and conversation going on in this virtual community, which crosses specialties and geography.

Last week, Dr. Javier Benítez (@jvrbntz) was tweeting a Question of the Day, referencing a 2010 Paucis Verbis card on overanticoagulation, which was based on the 2008 American College of Chest Physicians (ACCP) guidelines. About 8 minutes after I retweeted his question, Dr. Roy Arnold (@cholerajoe), a pulmonary/critical care physician kindly informed me that the 2012 ACCP guidelines have been out since February.

So this PV card is replacing the 2010 card with revised recommendations. For more in-depth discussion, definitely take a look at Dr. Scott Weingart’s great podcast over at EMCrit. He helps to clarify holes which the 2012 ACCP guidelines don’t really address such as:

What if the patient is minorly bleeding with a high INR?

Oral vitamin K and 15 mL/kg FFP

What if you only have the 3-factor PCC (factors II, IX, X) and not the recommended 4-factor PCC (factors II, IX, X plus factor VII)?

If PCC is indicated, add recombinant factor VIIa or FFP to the 3-factor PCC to cover for factor VII.

Mythbuster: The 10% cephalosporin-penicillin cross-reactivity risk

To give or not to give a cephalosporin in penicillin-allergic patients?

I remember back to my days in pharmacy school when I learned that there was approximately a 10% risk of cross-reactivity, if a cephalosporin was given to a penicillin-allergic patient. They probably said something about the risk being less with 3rd and 4th generations cephalosporins, but lets be honest… who remembers anything but that magic 10%? When I started working more with physicians, I found that they also learned the same 10% rule in medical school. Well, I guess that means it’s fact, right? Not so fast!

Sort me! Paucis Verbis cards now catalogued

After much recent feedback on the poll about the Paucis Verbis cards (thanks to all who responded!), I see trends:

Several have commented that it is getting increasingly difficult to find a card that they are searching for. There are over 100 cards now! So, I managed to figure out how to embed a Google Doc spreadsheet into the blog, which now allows you to sort and search for particular cards (minor HTML coding necessary). This list will permanently live on the Paucis Verbis page.

Poll: Is anyone using the Paucis Verbis cards?

Feedback is essential for continued growth and improvement in any longitudinal project that you work on.

Thus annually, I conduct a poll to see if I can improve anything on the blog. This year, I wanted to focus on the Paucis Verbis pocket cards. There are over 100 cards now, which are each based on recent peer-reviewed publications. I try to make them as practical as possible with the goal of improving evidence-based practice at the bedside.

Paucis Verbis: D-Dimer test

D-Dimer: To order or not to order?

That’s the question when it comes to risk stratifying a patient for a pulmonary embolism with a low pretest probability. One should consider confounding conditions which may cause an elevated D-Dimer level. There’s always confusion about what may cause an elevated D-Dimer besides venous thromboemboli. So I thought I would make a pocket card as a reminder.
