THE LESS HEALTH CARE THE BETTER:

When there is a plane crash in the U.S., even a minor one, it makes headlines. There is a thorough federal investigation, and the tragedy often yields important lessons for the aviation industry. Pilots and airlines thus learn how to do their jobs more safely.

The world of American medicine is far deadlier: Medical mistakes kill enough people each week to fill four jumbo jets. But these mistakes go largely unnoticed by the world at large, and the medical community rarely learns from them. The same preventable mistakes are made over and over again, and patients are left in the dark about which hospitals have significantly better (or worse) safety records than their peers.

As doctors, we swear to do no harm. But on the job we soon absorb another unspoken rule: to overlook the mistakes of our colleagues. The problem is vast. U.S. surgeons operate on the wrong body part as often as 40 times a week. Roughly a quarter of all hospitalized patients will be harmed by a medical error of some kind. If medical errors were a disease, they would be the sixth leading cause of death in America--just behind accidents and ahead of Alzheimer's. The human toll aside, medical errors cost the U.S. health-care system tens of billions a year. Some 20% to 30% of all medications, tests and procedures are unnecessary, according to research done by medical specialists, surveying their own fields. What other industry misses the mark this often?

It does not have to be this way. A new generation of doctors and patients is trying to achieve greater transparency in the health-care system, and new technology makes it more achievable than ever before.
