When you need the best care medicine has to offer, chances are you can find someone with the required skills in the United States. Whether it involves repairing a sick heart or blasting a cancerous clump of cells deep within the brain with a precisely targeted beam of radiation, advanced care is so widely available that America's health system long claimed bragging rights for providing the best care on Earth.
Then came a scathing report, now 13 years old, from the Institute of Medicine, a quasi-government think-tank known for tackling some of the toughest issues in healthcare. It charged that errors and unsafe practices in U.S. hospitals may kill nearly 50,000 patients a year, possibly even twice that number. A flurry of studies released since then show that the hazards in U.S. healthcare persist today—nasty bugs passed on to patients in hospitals and clinics, unneeded and risky tests and procedures, medications that hurt more than help, treatment guidelines that are overlooked or ignored, doctors who base treatment decisions on instinct rather than evidence, computerized health information technology that should make care safer and more efficient but too often does the opposite—and the list is still growing.
The question, then, is: How can you take advantage of the strengths of the U.S. healthcare system and not be harmed by its weaknesses? The answer, in six words: Get only the healthcare you need.
The less you put yourself at the mercy of doctors and hospitals, the less likely you will be harmed. That means staying healthy. It means getting the right kind and right amount of preventive care, not too much and not too little. It means—and this isn't easy—not overreacting to information that sounds alarming. It also means getting a second opinion when you need one, preferably from a doctor who can be objective and doesn't have a stake in the outcome of your case.
"Be skeptical, ask questions, get information from different sources. Be more assertive and inquisitive," says David Goodman, a principal investigator at the Dartmouth Atlas of Health Care, a research project that has shown, among other things, that patients don't necessarily fare better in places where doctors and hospitals are more aggressive, and that far too often they do much worse.
What does the right amount of preventive care mean? That depends on the state of a person's health, along with age, sex, and family history. Not everyone needs an annual physical exam, as long as he or she is healthy and without a family history of premature disease. "One basic principle," Goodman says, "is that if you're living well and feeling healthy, don't go looking for trouble." Unless you're overweight, you should get your blood pressure checked every two years after the age of 18, and more often once you turn 40. Most women don't need annual Pap smears. The U.S. Preventive Services Task Force (USPTF) says it's okay to hold off for up to three years. Keeping vaccinations current is a valuable way to stave off a list of preventable illnesses, from flu to cervical cancer (through human papilloma virus vaccine). Flu and pneumonia shots are especially important for people 65 and older, both to avoid the diseases and their potentially dangerous complications. Take your doctor seriously when she talks about good and bad fats in the diet and the value of dropping even a few pounds. Colonoscopy, unpleasant as it is, can be a life-saver. It's recommended at least once every five years for people 50 and older, because colonoscopy reduces the risk of dying from colon cancer by as much as 77 percent. Each year, a million people are diagnosed with colon cancer worldwide, and 500,000 of them die.
