Americans don't know how to determine which doctor will provide high-quality care, often choosing a doctor based on insurance and if the doctor is friendly, according to a poll from The Associated Press-NORC Center for Public Affairs Research. Only 22 percent of survey respondents said they were confident they could compare information to choose the best doctor. Sixty percent said they trust doctor recommendations from friends or family, and about half value referrals from their regular physician. Far fewer trust quality information from online patient reviews, health insurers, ratings web sites, the media and the government. While only 4 percent believe they receive poor-quality care, about half believe that high-quality care is more expensive. Poll results
