CT Scan Risks: Radiation Danger and Overuse Threatens Patients

Many patients erroneously believe that x-rays and CAT scans have no risk. In their minds, they are non-invasive studies that can cause no harm. Since there are no incisions or anesthesia, they regard the experience as having the same risk as taking a family photograph. How wrong they are.  In my mind the danger from non-invasive radiology studies may surpass the risk of hard core medical treatment. True, radiology tests won’t puncture an organ or a blood vessel, as a surgeon or a gastroenterologist can. Imaging studies do not cause direct damage, but they may lead patients onto the medical battlefield. These diagnostic tests are an insidious force that draws patients into a spiral of direct risk and medical overutilization. Is this post a shot at radiologists? No, it’s a shot at all of us. Remember, radiologists never order CAT scans; the rest of us physicians do. I certainly am distressed with the obsessive manner that my radiology colleagues interpret studies today, identifying inn

Why Total Body Scans are Scams: Maze vs Bayes

Folks across the country are paying hard cash for total body scans, abdominal aortic aneurysm testing, CAT coronary artery scans and carotid artery evaluations to prevent disease or find important lesions early. It’s a seductive argument, and it’s a scam. Ordinary patients don’t understand about pre-test probability and positive and negative predictive values. Indeed, all physicians were taught to consider Bayesian theory when ordering diagnostic tests. This is very tough concept for patients to grasp. A critical principle of proper diagnostic testing can be summarized in a single sentence. If an individual is unlikely to have the medical condition under consideration, then a diagnostic test that yields a positive result is likely to be a false reading. Here is an illustration demonstrating why patients need to understand this issue. While the forthcoming example is hypothetical, I guarantee that every physician has seen very similar patients in their practices. While the pat

Should Physicians Give Up and Surrender?

Photo Credit More and more, I read about physicians who are ready to give it up. I hear similar views in the physicians lounge and in hospital hallways. These conversations are a modern phenomenon; they did not occur when I entered the profession 20 years ago. They have germinated as a result of rising forces that have demoralized many practitioners. Some of them include: • Loss of autonomy • Loss of income • Loss of stature and prestige • Required ‘Quality’ initiatives • Health care ‘reform’ • Infighting within the medical profession • EMR • Medical liability system • Insurance company hurdles to get paid • General gerbil wheel existance Luckily for me, I am still happy on the job. Of course, I am not immune to the above realities, and would readily accept a vaccine to protect against them, if one existed. I try to focus on the core purpose of being a physician, and work to sequester the noise and static, at least while a patient is seated before me. Since I am a memb

Will Smarter Lawyers End Frivolous Lawsuits?

How do you know if a lawyer is any good?  Of course, they've all passed the bar, but now their profession is lowering it.  While most of us strive for excellence, and raise our children to value this virtue, prominent legal educators are establishing a new quality intitiative for their profession.  Who says that lawyers can't reform themselves?  Perhaps, we physicians can follow their bold example and raise the credentials of our pre-medical students.  I’ll present the facts. You be the judge. I have written a dozen posts on tort reform on this blog, which always generate spirited and adversarial retorts from attorneys and their supporters. They accuse me and other tort reform advocates of carrying water for insurance companies. They repeatedly point out that I know nothing about the legal system and are unqualified to opine on its flaws. They deride me when I argue that effective tort reform would reduce the practice of defensive medicine, despite the recent supportive concl

Are Direct-to-Consumer Drug Ads Right for You?

Should the public be shielded from medical information that can mislead it? Many argue against direct-to-consumer (DTC) advertising, which is omnipresent in print and on the airwaves. Opponents of this practice argue that it promotes the use of expensive medications when patients ask their doctors if the ‘drug is right for them’, the tag line that appears at the end of every ad. This phrase is the drug company’s limp disclaimer that it is really the physician who will make the prescribing recommendation. Yeah, right. Of course, DTC ads promote drug sales. Isn’t that the purpose of advertising? Antagonists of this drug pushing state that resources spent on advertising should be used instead to lower drug prices for consumers. Couldn’t the same argument be made about any product being advertised? Should General Motors cease and desist from spending marketing money and divert these funds instead for consumer rebates? Legal products have the right to advertise and market their wares. Per

FDA ‘Bad Ad’ Program Recruits Physicians. Pharma Beware!

Photo Credit One of the advantages of marrying an immigrant is having intense exposure to another culture. My wife’s Russian heritage, and her family, have enriched my own life immeasurably. The trip that I took with her and my brother to Russia in 1990, where she served as our personal translator, was unforgettable. During the early years of our relationship, I heard stories about her family that seemed incredible to an American like myself who was raised in ordinary cirumstances in suburbia. In Russia, her father, uncle and close relatives were arrested and imprisoned on absurd charges. Her family, like so many others, was subjected to persecution and anti-Semitism. One would imagine that her family would celebrate when Stalin died in 1953. Instead, I am told that my mother-in-law, whose family had suffered under his brutal fist, was in tears, demonsrating the deep reach that this tyrannical leader had on the populace. He had a cult of personality, an intoxicant that numbed the

Unneccesary Medical Tests: Tort Reform Can't Solve it All

Gastroenterologist's view of the stomach Recently, while covering for one of my partners on a weekend, I was consulted by a physician to do a procedure. The doctor wanted his patient to undergo an EGD, which is a scope test that examines the esophagus, stomach and first portion of the small intestine called the duodenum. We gastroenterologists do this test routinely to search for an explanation for a patient’s symptoms, or to determine if these organs might be harboring a lesion that is silently bleeding. Gastroenterologists are obligated to perform procedures for sound medical reasons. I have already confessed publicly on this blog why physicians like me have performed medical tests for the wrong reasons. The medical universe is not ideal, and neither are its players. Nevertheless, we want our care to make sense and not to waste dollars. For example, if a patient is suffering an acute headache, it would be hard to justify ordering a CAT scan of the abdomen, which would be unl
