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 »

The Associated Press ran a provocatively-titled piece recently, “Family health history: ‘best kept secret’ in care”, which noted how a geneticist at the Cleveland Clinic discovered that asking about family members and their history of breast, colon, or prostate cancer was better than simply doing genetic blood testing.
Surprising? Hardly. This is what all medical students are taught. Talk to the patient. Get a detailed history and physical. Lab work and imaging studies are merely tools that can help support or refute a diagnosis. They provide a piece of the puzzle, but always must be considered in the full context of a patient. They alone do not provide the truth. Read more »

We reviewed four stories on the Swedish mammography study that appeared in the journal Cancer last week. Three of the four stories gave a pretty clear indication that there were methodological concerns about the Swedish research (of the four reviewed, only HealthDay offered no such hint):
• 4th paragraph of AP story: “The new study has major limitations and cannot account for possibly big differences in the groups of women it compares.”
• 1st paragraph of LA Times blog story: “Critics charged that the study was poorly designed and potentially vastly misleading.”
• 2nd sentence of NY Times story: “Results were greeted with skepticism by some experts who say they may have overestimated the benefit.”
But none of the stories did a very complete job of explaining those potential limitations. Because of the confusion that must be occurring in the minds of women — especially those in their 40s — this is a time in which journalism must rise to the need and do a better job of evaluating evidence and helping readers make sense of what appear to be conflicting findings.
I was in Chapel Hill, North Carolina, when the study was published and had the chance to talk about it with former U.S. Preventive Services Task Force member, and a recognized thought leader on issues of prevention and especially of screening tests, Dr. Russell Harris, Professor and Director of the Health Care and Prevention Concentration of the University of North Carolina (UNC) School of Public Health.

I’ve written previously that many doctors are finding the physical exam obsolete, and are favoring more technologically-advanced, and expensive, tests. In fact, I alluded to traditional physical exam advocates as “arguing for staying with a horse and buggy when cars are rapidly becoming available.”
In a recent piece from the New York Times, internist Danielle Ofri says we need to look past the lack of evidence supporting the physical exam. The benefits of touching the patient, and listening to his heart and lungs, cannot be quantitatively measured:
Does the physical exam serve any other purpose? The doctor-patient relationship is fundamentally different from, say, the accountant-client relationship. The laying on of hands sets medical practitioners apart from their counterparts in the business world. Despite the inroads of evidence-based medicine, M.R.I.s, angiograms and PET scanners, there is clearly something special, perhaps even healing, about touch. There is a warmth of connection that supersedes anything intellectual, and that connection goes both ways in the doctor-patient relationship.
Great point. Read more »

Kudos to Christopher Snowbeck and the St. Paul Pioneer Press for digging into new Medicare data to report that the state the newspaper serves is out of whack with the rest of the country in how many expensive MRI scans are done on Minnesotans’ bad backs.
Snowbeck artfully captures the predictable rationalization and defensive responses coming from locals who don’t like what the data suggest. Because what they suggest is overuse leading to overtreatment. So here’s one attempt a provider makes to deflect the data:
“The Medicare billing/claims data, which this report is generated from, would not capture conversations between a patient and provider that may have addressed alternative therapies for lower back pain,” said Robert Prevost, a spokesman for North Memorial Health Care. “It’s important to recognize the limitations of this data.”
No, data don’t capture conversations. But wouldn’t it be fascinating to be a fly on the wall during those many patient-physician encounters that led to an MRI to see what level of truly informed shared decision-making (if any) took place? Read more »
