Not everything that is on the Web is reliable. Information and resources may be incomplete, inaccurate or out of date. [1-3] Some sites can also be intentionally misleading. It is therefore essential that users exercise judgement before accepting the material presented. There are various strategies that can be used.
Quality initiatives are one way in which website developers are encouraged to comply with appropriate standards.  CareSearch is an information partner of healthdirect an Australian Government initiative. This partnership reflects a shared vision to provide relevant and reliable health and related information to Australian consumers.
There have been several reviews of quality criteria relating to online health information. [5,6] A number of quality assessment tools and scales have also been developed. They include:
The Uniform Resource Locator (URL) is the web address of a page. It is displayed in the web browser when a page is open. For example the homepage URL for CareSearch is https://www.caresearch.com.au
The URL can include helpful information. For example, .com indicates that the domain is on a commercial server. University servers are indicated by .edu or .ac. Government servers are indicated by .gov. There are restrictions on who can access government and education servers.
The country of origin for the server is also part of the web address for many URLs. American sites often do not include a country code. Examples of country codes are:
When you run a search, you will often be taken directly to a page within a website. If there is no link to the home page, you can delete all of the URL after the domain and country code (eg .com.au) and then search. This should take you to the home page where you can find out more about who is providing the information. The 'About Us' section often provides useful information about authorship of the site.
One of the simplest ways of checking the quality of a piece of information is to see if it is consistent with other sources. Checking two or three sites may provide some indication as to consistency or disagreement.
