Uncontrolled bleeding is the bane of trauma professionals everywhere. Early in a resuscitation, we focus on identifying potential sources. We’ve developed numerous techniques for plugging them up. And we have processes in place to replace the blood that’s been lost. Unfortunately, blood products are a perishable item. Packed red blood cells have a typical shelf-life of 42 days.

Evaluation of unintentional injury and trauma is one of the hallmarks of the EM and PEM physician. One of the most difficult and most satisfying parts of pediatric emergency medicine is using one’s history, exam and clinical tools to make an informed decision and spare children from unnecessary pain , uncomfortable exams, painful procedures and medical imaging.

Regardless of the reason for a primary care visit in the United States, patients are routinely asked how often they feel “hopeless” or "like a failure” These questions come from the PHQ-9. The PHQ-9 has since been validated and is now widely used to screen for depression. Since the United States Preventive Services Task Force (USPSTF) first recommended depression screening 22 years ago, the practice has become standard in primary care despite an absence of evidence.

Resuscitative thoracotomy is a (sometimes) life-saving procedure reserved for trauma patients in extremis. Thankfully, most trauma centers do very few of these a year. However, that makes it one of those “high severity – low frequency” procedures that generate many, many quality improvement problems. Many of these issues are due to operator unfamiliarity or equipment availability.

In my last post, I reviewed using the Cribari grid to evaluate over- and under-triage at your trauma center. This technique has been a mainstay for nearly two decades but has shortcomings. The most important one is that it relies only on the Injury Severity Score (ISS) to judge whether some type of mistriage occurred. The ISS is usually calculated after discharge, so it can only be applied after the fact.
