Delayed Hemothorax In Older Adults: Real Or Not?

Leave a comment

I came across an interesting paper in the Journal of Trauma & Acute Care Surgery Open recently. I always read these articles a bit more critically, though, because the peer review process just doesn’t feel quite the same to me as the more traditional journal process. But maybe it’s just me.

In this paper, the authors decided to look at the incidence of delayed hemothorax because “emerging evidence suggests HTX in older adults with rib fractures may experience subtle hemothoraces that progress in a delayed fashion over several days.” They cite two references to back up this rationale.

They retrospectively reviewed records from two busy US Level I trauma centers for adults age 50 or older who were diagnosed with delayed hemothorax (dHTX). Delayed was defined as 48 hours or more after initial chest CT showed either a minimal or trace HTX. The authors went on to analyze the characteristics and demographics of the patients involved.

Here are the factoids:

  • A total of 14 older adults experienced dHTX after rib fractures, an overall incidence of 1.3% (!)
  • About half were diagnosed during the initial hospitalization for the fractures
  • All patients had multiple fractures, with an average of 6 consecutive ones; four had a flail chest
  • One third progressed from a trace HTX, two thirds had a completely negative initial chest CT
  • Only one third were taking anticoagulants or anti-platelet agents
  • Patients with multiple fractures, posteriorly located, and displaced were most likely to develop dHTX

The authors concluded that “delayed progression and delayed development of HTX among older adults with rib fractures require wider recognition.”

Bottom line: Really? First, I looked at the papers cited by the authors as the rationale for doing this study. They each found dHTX in about 10% of patients, but their definition was very broad: any fluid visible on upright chest x-ray. Furthermore, the patients were not really “older” either. Average age was around 50. 

So I’m not sure yet whether this is a problem, especially with the low incidence of 1.3%. This study doesn’t come right out and state how many patients they reviewed to find their 14, but it can be calculated to be 14 / 1.3% = 1,177. This incidence is only one tenth of that found in the two studies cited. Seems relatively uncommon, and half were discovered while the patients were still in the hospital. Thus only 0.65% sought readmission for chest discomfort or difficulty breathing.

This study required chest CT for rib fracture diagnosis. Is all that radiation (and possibly contrast) really necessary? And did these patients get another chest CT to delineate the pathology? More radiation?

Overall, this paper was not very helpful to me. Yes, I have seen patients come back days or weeks later with a hemothorax that was not seen during their first visit. It’s just that this study raises many more questions that should have been easily answered in the discussion. But they weren’t.

Given that only about a half of a percent of rib fracture patients develop delayed hemothorax after discharge, it is probably prudent to provide information to the patient recommending they see their practitioner if they develop any symptoms days or weeks later.  And a simple chest x-ray should do.

What Is The Curbside Consult? And The ELEVENTH Law of Trauma!

Leave a comment

Surgeons, I’m sure you’ve had an experience something like this at some point:

You happen to be wandering through the emergency department and one of your Emergency Medicine colleagues approaches you and says, “Hey, I ‘ve got this patient I’m seeing that I just want to run by you…”

How should you deal with this? They want a quick tidbit of information to help them decide what to do with the patient. Can they send them home, or should they “formally” consult you?

It’s important to look at the pros and cons of this practice. First the pros:

  • It’s direct. You’re right there. No phone calls, no paging.
  • It’s quick. Just a quick description  of the problem, and a prompt answer. Then everyone can get on with their business.

But then there are the cons:

  • Situational accuracy. The consultee has not seen the patient, so the information they have been given was filtered through the consulter. Any number of cognitive biases are possible, so the real story may not be exactly as it seems.
  • Interpretation of the recommendation. Other cognitive biases are also possible as the consulter acts on and implements the recommendations of the consulter. Have they really been followed?
  • Lack of documentation. This is the biggest problem with a curbside consult. The consultee may act without documenting the source of the recommendation. Or, they may document that they spoke with Dr. Consultee. In either case, one or the other may be hung out to dry, so to speak.

Consider what happens if there is a complication in the care of that patient. There is no way to really determine what was said during that conversation a week or two years later. It boils down to recollections and may end up as a he said … she said situation. And in the worst case scenario, if such a case were to enter the medicolegal arena, there is no official record that any recommendation was made or followed. It’s a very easy case for the plaintiff’s attorney to prevail.

So this leads to my new Eleventh Law of Trauma:

“Work not documented is work not done“

Bottom line: There is no such thing as a curbside consult! The consultee should say, “I’d better take a look at this patient, why don’t you officially consult me?”

In doing this, the consulter gets to use their own clinical and cognitive skills, and thus render a real opinion based on first hand experience. The consultee gets the most accurate recommendations possible, and they are noted in the record so there is no room for misinterpretation. And finally, there is good documentation from both that will stand up in a court of law if needed.
