In The ER With Abdominal Pain? Lower Your Diagnosis Expectations

Abdominal pain is the bane of many emergency physicians. Recently, I wrote how CT scans are on the rise in the ER. Much of those scans look for potential causes of abdominal pain.

In an essay from Time, Dr. Zachary Meisel discusses why abdominal pain, in his words, is the doctor’s “booby prize.” And when you consider that there are 7 million visits annually by people who report abdominal pain, that’s a lot of proverbial prizes.

One reason is the myriad of causes that lead bring a patient to the hospital clutching his abdomen. It can range from something as relatively benign as viral gastroenteritis where a patient be safely discharged home, to any number of “acute” abdominal problems necessitating surgery.

But more importantly, we need to consider how limited doctors actually are in the ER. Consider the ubiquitous CT scan, which is being ordered with increasing regularity:

The pros: CT scans are readily available, able to look at every organ in the abdomen and pelvis, and very good for ruling out many of the immediately life-threatening causes of belly pain. CT scans can also reduce the need for exploratory surgery. The cons: Often, CTs can’t diagnose the actual cause of ER patients’ abdominal pain. Worse, CTs deliver significant doses of radiation to a patient’s abdomen and pelvis (equivalent to between 100 and 250 chest X-rays). Over a lifetime, patients who receive two or three abdominal CT scans are exposed to more radiation than many Hiroshima survivors.

Add that to the fact that patients expect a definitive diagnosis when visiting the hospital — one that doctors can’t always give when it comes to abdominal pain. Read more »

Reassuring Patients About CT Scans And Radiation Risks

Emergency patients with acute abdominal pain feel more confident about medical diagnoses when a doctor has ordered a computed tomography (CT) scan, and nearly three-quarters of patients underestimate the radiation risk posed by this test, reports the Annals of Emergency Medicine.

“Patients with abdominal pain are four times more confident in an exam that includes imaging than in an exam that has no testing,” said the paper’s lead author. “Most of the patients in our study had little understanding of the amount of radiation delivered by one CT scan, never mind several over the course of a lifetime. Many of the patients did not recall earlier CT scans, even though they were listed in electronic medical records.”

Researchers surveyed 1,168 patients with non-traumatic abdominal pain. Confidence in medical evaluations with increasing levels of laboratory testing and imaging was rated on a 100-point scale. Then, to assess cancer risk knowledge, participants rated their agreement with these factual statements: “Approximately two to three abdominal CTs give the same radiation exposure as experienced by Hiroshima survivors,” and “Two to three abdominal CTs over a person’s lifetime can increase cancer risk.” Read more »

Screening For Lung Cancer: New Findings And Continued Controversy

Lung cancer screening has been an area of considerable controversy. Before today, there had been no evidence that screening patients for lung cancer, either with a CT scan or chest x-ray, saved lives.

For years, doctors have been waiting for the results of the large, randomized National Lung Screening Trial (NLST), conducted by the National Cancer Institute.

[Yesterday] it was announced that the trial was stopped early, with a bold, positive finding:

All participants had a history of at least 30 pack-years, and were either current or former smokers without signs, symptoms, or a history of lung cancer.

As of Oct. 20, 2010, the researchers saw a total of 354 deaths from lung cancer in the CT group, compared with 442 in the chest x-ray group.

That amounts to a 20.3% reduction in lung cancer mortality — a finding that the study’s independent data and safety monitoring board decided was statistically significant enough to halt the trial and declare a benefit.

Previously, only breast, colon, and cervical cancer has had the evidence back up its screening recommendations. It’s still early in the game, but it appears that lung cancer may be following in that same path. That said, there are a variety of concerns before opening up the floodgates to screening chest CTs.
