What makes something a “landmark” critical care trial?

I receive quite a bit of feedback regarding one of my more popular mobile applications, ICU Trials by ClinCalc.  Often, these emails involve a request to add a particular “landmark” trial with the next application update.  With 10-20 recent requests for new trial additions, I’ve been forced to re-evaluate my criteria for what constitutes a […]

What is the best evidence for pharmacologic VTE prophylaxis in trauma patients?

Is there a preferred agent for VTE prophylaxis in trauma patients?  Is there a superior dosing strategy for these high-risk patients? The selection and dosing of pharmacologic VTE prophylaxis in trauma patients has a troubled, controversial past.  The literature surrounding the topic is riddled with small, conflicting trials and methodological flaws.

Is there a maximum insulin glargine (Lantus) dose?

Is there a maximum insulin glargine (Lantus) single-injection dose?  Anecdotally, I have heard that patients receiving more than 50 units should split the dose from daily dosing to twice-daily.  What’s the evidence? The question of a maximum insulin glargine dose is not straightforward because it encompasses several issues:

New Painless Tool for Finding MIC Breakpoints

MIC breakpoints for antimicrobials are not easy to look up — until now. CLSI, the governing body in the United States for breakpoints, hides their data behind a $250+ book called M100.  For clinicians who do not work in a microbiology lab or have access to the M100 book, it is difficult to find published […]
