Emergency Room Not Diagnosing A Concussion, Revisited

A few months ago, I wrote a short article describing why emergency rooms do such a bad job at diagnosing concussions/brain injuries: The emergency room didn’t say anything about a concussion. Does that mean I don’t have a brain injury?

Recently,  I came across a study that really quantifies the problem I discussed.

The study, primarily led by several doctors from the University of Washington, was laid out in an article entitled Accuracy of Mild Traumatic Brain Injury Diagnosis, which was published in the August 2008 issue of the Archives of Physical Medical Rehabilitation.

The article starts by noting:

Accurate identification and diagnosis of a mild TBI is the first step toward providing clinical care.

Unfortunately, despite the accurate diagnosis of a brain injury being so important, the study found that emergency rooms are not very good at making the diagnoses.

The study looked at 197 patients who had been to emergency rooms.  They looked at medical records, and in some cases interviewed the patients, to determine whether they patients had a brain injury, as defined by the Centers for Disease Control mild Traumatic Brain Injury work group.  The researchers then took those patients who were diagnosed with a brain injury and looked at the patients’ emergency room records to see what was diagnosed in the emergency room.

The results were startling.

The emergency room doctors failed to make a diagnoses of a head injury or concussion in 56% of the patients who were later determined to have a brain injury.

That’s a stunning number.

There are some things that can help improve the accuracy of the emergency department physicians.  If the patient complained in the emergency room about confusion, feeling dazed, or having memory problems, then the diagnoses was more accurate.  However, even with those findings, the emergency department still missed the diagnoses on 37% of the patients.  That’s still a substantial number of patients who have a brain injury that doctors are missing.

Oddly, the emergency room physicians’ diagnoses weren’t dramatically better even when the patient reported a loss of consciousness — which should be a red flag.  The doctors still failed to make the proper diagnoses of a head injury in about 50% of the patients who had told the doctors that they had lost consciousness.

This means that you have to be diligent about noticing symptoms.  I’ve repeatedly written that misdiagnoses is a problem and that the best way to find the problem and to get proper treatment for the problem is for someone close to the person to look for symptoms.
