  • Use the information you find to become an informed patient. Discuss what you have learned with your medical care providers.
  • When reviewing information you have uncovered, look for dates — how old is the information?
  • Be a critical consumer, ask questions: Has this document been updated? Is there a point-of-contact for the information? Are there any references? Has the information been peer reviewed (critically examined by credentialed professionals)?
  • Remember that the distinction between a paid ad and public service announcements may not be obvious on the Web.
  • Federal, State and even local government often provide health information. Look at the domain name of the site you have found — sites ending in GOV and ORG generally reflect Federal or State sources or non profit organizations.
