A group of older adults are gathered for their weekly computer class. They are learning to use the Internet to find health information. Maria's husband, who is 75, had a stroke the month before so she's searching the web for some basic facts about stroke rehabilitation. Walter, who is 68, has questions about what causes Alzheimer's disease because he thinks that's what his mother had. Shirley and Howard, married for 48 years, are trying to find out if the cataract surgery their eye doctor suggests really is as safe as he says. The whole group has one big worry—"How can we trust the health information we get on the Internet?"
There are thousands of health-related websites on the Internet. Some of the information on these websites is reliable. Some of it is not. Some of the information is current. Some of it is not. Choosing which website to trust is worth thinking about.
As a rule, health websites sponsored by Federal government agencies are good sources of health information. You can reach all Federal websites by visiting www.usa.gov . Large professional organizations and well-known medical schools may also be good sources of health information.
The main page of a website is called the home page. The home page shows you the features on the website. You should be able to spot the name of the sponsor of the website right away.
Places To Start
There are a few good places to start if you are looking for online health information. An excellent source of reliable information is the National Institutes of Health (www.nih.gov ). You can start here to find information on almost every health topic, including:
In addition, you can visit the National Library of Medicine's Medline Plus (www.medlineplus.gov ) for dependable information on more than 700 health-related topics.
You can also visit NIHSeniorHealth.gov (www.nihseniorhealth.gov )—a website with health information designed specifically for older people.
As you search online, you are likely to find websites for many health agencies and organizations that are not well-known. By answering the following questions you should be able to find more information about these websites. A lot of these details can be found under the heading, "About Us" or "Contact Us."
Who sponsors the website? Can you easily identify the sponsor?
Websites cost money—is the funding source readily apparent? Sometimes the website address itself may help—for example:
Is it obvious how you can reach the sponsor?
Trustworthy websites will have contact information for you to use. They often have a toll-free telephone number. The website home page should list an e-mail address, phone number, or a mailing address where the sponsor and/or the authors of the information can be reached.
Use your common sense and good judgment when evaluating health information online. There are websites on nearly every conceivable health topic and no rules overseeing the quality of the information. Take a deep breath and think a bit before acting on any health information you find on the web. Don't count on any one website. If possible, check with several sources to confirm the accuracy of your results. And remember to talk with your doctor.
Here are some helpful Federal and non-Federal resources.
