Reid's first stop is the U.K., where the government-run National Health Service (NHS) is funded through taxes. "Every single person who's born in the U.K. will use the NHS," says Whittington Hospital CEO David Sloman, "and none of them will be presented a bill at any point during that time." Often dismissed in America as "socialized medicine," the NHS is now trying some free-market tactics like "pay-for-performance," where doctors are paid more if they get good results controlling chronic diseases like diabetes. And now patients can choose where they go for medical procedures, forcing hospitals to compete head to head.
