Is More Really Better?
August 23, 2011
That less health care can lead to better health and, conversely, that more health care can harm health, runs counter to most patients' conviction that screenings and treatments are inherently beneficial. That belief is fueled by the flood of new technologies and drugs that have reached the market in the past two or three decades, promising to prevent disease and extend life. Most of us wouldn't think twice if our doctor offered a test that has the power to expose a lurking tumor, or a clogged artery, or a heart arrhythmia. Better to know -- and get treated -- than to take any risks, the reasoning goes, says Newsweek.
- In fact, for many otherwise healthy people, tests often lead to more tests, which can lead to interventions based on a possible problem that may have gone away on its own or ultimately proved harmless.
- Patients can easily be fooled when a screening test detects, or an intervention treats, an abnormality, and their health improves, says cardiologist Michael Lauer of the National Heart, Lung, and Blood Institute.
- In fact, says Lauer, that abnormality may not have been the cause of the problem or a threat to future health: "All you've done is misclassify someone with no disease as having disease."
Experts estimate that the United States spends hundreds of billions of dollars every year on medical procedures that provide no benefit or a substantial risk of harm, suggesting that Medicare could save both money and lives if it stopped paying for some common treatments. "There's a reason we spend almost twice as much per capita on health care [as other developed countries] with no gain in health or longevity," argues Dr. Steven Nissen, a cardiologist at the Cleveland Clinic. "We spend money like a drunken sailor on shore leave."
