Today, while surfing I noticed Librarian.net just referenced a 2002 Pew Report Vital Decisions: How Internet users decide what information to trust when they or their loved ones are sick.

Abstract:
In a national survey conducted March 1-31, 2002, the Pew Internet Project found that 62% of Internet users, or 73 million people in the United States, have gone online in search of health information. Experts say that Internet users should check a health site’s sponsor, check the date of the information, set aside ample time for a health search, and visit four to six sites. In reality, most health seekers go online without a definite research plan. The typical health seeker starts at a search site, not a medical site, and visits two to five sites during an average visit. She spends at least thirty minutes on a search. She feels reassured by advice that matches what she already knew about a condition and by statements that are repeated at more than one site. She is likely to turn away from sites that seem to be selling something or don’t clearly identify the source of the information. And about one third of health seekers who find relevant information online bring it to their doctor for a final quality check. An addendum to this report includes a guide from the Medical Library Association about smart health-search strategies and good Web sites.

This fits perfectly with Librarians' Rx blog on the new Pew Report on Health Information Online and my blog on users evaluating online medical information.
