10 Things to Know about Evaluating Medical Resources on the Web
The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading. This short guide contains important questions you should consider as you look for health information online. Answering these questions when you visit a new site will help you evaluate the information you find.
1. Who runs this site? Any good health-related Web site should make it easy for you to learn who is responsible for the site and its information. On this site, for example, the National Cancer Institute is clearly marked on every major page of the site, along with a link to the NCI homepage.
2. Who pays for the site? It costs money to run a Web site. The source of a Web site's funding should be clearly stated or readily apparent. For example, Web addresses ending in ".gov" denote a federal government-sponsored site. You should know how the site pays for its existence; does it sell advertising? Is it sponsored by a drug company? The source of funding can affect what content is presented, how the content is presented, and what the site owners want to accomplish on the site.
3. What is the purpose of the site? This is related to who runs and pays for the site. Check the "About This Site" link, which appears on many sites. The purpose of the site should be clearly stated and should help you evaluate the trustworthiness of the information.
4. Where does the information come from? Many health/medical sites post information collected from other Web sites or sources. If the person or organization in charge of the site did not create the information, the original source should be clearly labeled.
5. What is the basis of the information? In addition to identifying who wrote the material you are reading, the site should describe the evidence that the material is based on. Medical facts and figures should have references (such as an article in a medical journal). Also, opinions or advice should be clearly set apart from information that is "evidence-based" (that is, based on research results).
6. How is the information selected? Is there an editorial board? Do people with excellent medical qualifications review the material before it is posted?
7. How current is the information? Web sites should be reviewed and updated on a regular basis. It is particularly important that medical information be current, and that its most recent update or review date is clearly posted. Even if the information has not changed, you want to know that the site owners have reviewed it recently to ensure that it is still valid.
8. How does the site choose links to other sites?Web sites usually have a policy about how they establish links to other sites. Some medical sites take a conservative approach and don't link to any other sites; some link to any site that asks, or pays, for a link; others only link to sites that have met certain criteria.
10. How does the site manage interactions with visitors? There should always be a way for you to contact the site owners with problems, feedback and questions. If the site hosts chat rooms or other online discussion areas, it should tell visitors what the terms of using this service are. Is it moderated? If so, by whom, and why? It is always a good idea to spend time reading the discussion without joining in, so that you feel comfortable with the environment before becoming a participant.
