Using health information from the Web

You can find a lot of useful health information on the World Wide Web. That's why many people bring printouts from Web sites to doctor appointments. This is a good way to start a discussion, and your doctor can help determine if the information applies to you.

Online pointers

When going online for health information, keep the following in mind:

• The information you find should never replace your doctor's advice. Your physician can review your health history and do a medical exam when appropriate; that's the best way to find answers to specific health issues.
• Not all health advice on the Internet is sound. In fact, some can harm you.
• Look for HON approval. HON stands for the Health On the Net foundation, a self-governing, international body that developed a code of ethical conduct or "good behavior" for presenting medical information online. HON-approved sites strive to maintain that code, which includes clearly stating the source and purpose of the information provided.

Reliability questions

These questions can help you determine if a site has reliable health information.

Purpose

• Is the site's purpose clearly stated?
• Is the information presented meant to educate, advertise or advocate?
• Who is the intended audience?
• Who sponsors the site? Are they trying to sell anything?

Content

• Does the information seem objective, or is it someone's opinion?
• Who produces and/or reviews the content? Are his or her credentials listed? Can you contact him or her?
• Is the information backed by research? Are sources listed and verifiable?
• When was the information last updated?

Timeliness

• When was the site first produced and last updated? Are such dates easily located?
• If there are links to other sites, are they appropriate and working?

Privacy

• Does the site have a privacy policy? Is it clear how any information you provide may be used?
• What kind of information are they collecting?
• Can you access information without giving personal information?
