Online Medical and Health Sites

My Favorite Web Sites - Winchester Star - 2/1/01
 by Martin Zombeck

This is a biweekly column providing an annotated list of web sites that may be of interest to the community. Each column will list sites that belong to a particular category: search engines, art, online newspapers & magazines, health and medicine, history, business and economics, etc. or sites relevant to a particular season, e.g., skiing, gardening. Most sites will be non-commercial. To make it easier to access the sites, each biweekly column will be posted on the Town of Winchester's web site one week after publication so that the sites can be accessed and bookmarked without having to be typed. Previous columns will be archived at the Winchester site, also.

The web is a useful source of medical information for the layman. Unfortunately, it is also a source of much medical misinformation. Many sites of unknown provenance provide misleading, inaccurate, and merely anecdotal information. Many commercial sites bombard the unwary with advertisements for medical products of dubious value. No one checks the validity of the information of most of the sites that are placed on the web - anyone can set up a web site and start dispensing "medical information". At the moment the underlying principle of the web is caveat emptor not caveat actor. Since most of us are not medical experts, how do we make use of the web to find reliable information? Here are some simple checks that you can perform to gauge the reliability of a medical web site:

  1. Are the author's/institution's credentials clearly displayed? You are most likely to find reliable information at the web sites of medical centers, university hospitals, and U.S. government health institutes.
  2. Are bibliographic references (and links) given to data sources and medical studies?
  3. Is the date of last modification shown? Is the information up-to-date?
Be skeptical and get a second opinion - look up the same information at another site. An informative article on using the web, On-Line Health Care for the Savvy Surfer, can be found at
