Medical Testing That Can Do More Harm Than Good

12 Medical Tests That Can Do More Harm Than Good

Enter a new term into the midlife vernacular: medical gluttony. It's when our doctors order a barrage of "just in case" medical testing to keep us happy. It's a practice that ratchets up the cost of medical care in America -- not just for insurance companies, but also for patients in the form of deductibles and co-pays. And because medical tests and procedures frequently carry their own set of risks, it can actually cause more harm than do good.

Doctors, however, may not be where the problem originates. Boomers are a generation with a strong sense of entitlement and nowhere is this felt more than in our approach to medical care. We want no stone left unturned in determining what's wrong with us and once we know, we demand the latest and greatest medical testing and treatments known to man regardless of its cost. When we have a persistent headache, we want our doctor to test and rule out a brain tumor and when we are fatigued, we want tests to rule out Lupus, chronic fatigue syndrome, Lyme Disease and a host of other ailments we self-diagnose on WebMD.

Doctors are, of course, our willing co-conspirators in our medical gluttony; they may be practicing "defensive medicine" to avoid lawsuits or have a financial stake in the testing companies. We've all been there: You go to see the doctor with a simple complaint and it unleashes a torrent of blood work, scans, and in some cases, tests that expose you to more serious complications than the complaint that brought you to seek care in the first place.

When head of the Centers for Medicare and Medicaid Services Don Berwick resigned, he said almost 30 percent of health care spending was a "waste" with no benefit to patients. Overtreatment was one of the top reasons he cited. A study released this month by The Commonwealth Fund came to a simliar conclusion.

How can tests do more harm than good? That's the premise of "How We Do Harm: A Doctor Breaks Ranks About Being Sick in America," a book by Dr. Otis W. Brawley, chief medical officer of the American Cancer Society. Brawley takes issue with doctors who prescribe too many tests, procedures and drugs.

In the book, he talks about the case of Ralph DeAngelo, whose medical odyssey began when his wife spotted an ad for a free prostate cancer screening and insisted he go. DeAngelo's results were found to be “significantly abnormal,” and in the course of his treatment, he had 12 biopsies; his prostate removed; and followup radiation therapy that created a hole between his rectum and bladder and required a colostomy. He later died of a urinary tract infection. Brawley said that the original free prostate specific antigen (more commonly known as PSA) test given to DeAngeleo, who was 72 when diagnosed and died five years later, showed a slightly elevated level of prostate-specific antigen -- something that may have been caused by an enlarged prostate gland common in older men -- and not cancer.

It was a case of overtreatment, said Brawley, and unfortunately not atypical. He notes that prostate cancer screenings have been done since 1991, but the first study showing that they even might be beneficial wasn't done until 2010.

Brawley also points to breast cancer treatment. For 20 years, breast cancer patients were routinely treated with a bone-marrow transplant and high-dose chemotherapy regimen. In the late 1980s, women en masse sued their insurance companies to get them to pay for it. Only later, in 1999, after four studies showed that having bone-marrow transplants was actually harmful in treating breast cancer, did the procedures stop. Within four months of the studies' release, 220 centers stopped doing them. Brawley said that 60,000 women had the procedure done in 1998 alone; none got it in the year 2000. Yet 10 states still have laws on the book requiring insurers to pay for them.

People, especially post 50s, Brawley said, "believe that the newest treatments must always be better than the older ones. Boomers believe that they simply must have the newest surgical techniques, even if they don't really need them." He points to coronary artery grafting -- bypass surgery -- as an example. There are many people who would have been just as fine with medical management of their clogged arteries, he said, but instead are subjected to -- and want -- the bypass surgeries. "We have done this time and time again in history. Too many tonsilectomies, too many tubes put in kids' ears -- even now we treat colds and viruses with powerful antibiotics that later weaken our bodies' ability to fight off more serious infections with them."

Brawley notes that while United States holds the No. 1 spot for health care spending, it ranks 50th among all nations in life expectancy.

So what's the answer? Politicians have been scaring folks with talk of rationing medicine. Maybe the discussion should be about the rational use of it instead.
