Critically Evaluating Online Resouces

Understanding Information Literacy

Information Literacy is the ability to evaluate what you read and write, to recognize when information is needed and to be able to independently locate, evaluate, and apply the needed information.

In the five step model of Evidence Based Medicine, Information Literacy specifically addresses how to APPRAISE the evidence/resource to examine its worth and reliability.



Assess Ask Acquire Appraise Apply
ASSESS

Assess the patient and the problem to determine the pertinent issues which may include differential diagnosis, treatment decisions, or prognosis

ASK

Ask a clear, answerable question to be pursued.

ACQUIRE

Acquire the evidence from appropriate sources.

APPRAISE

Appraise the evidence to further examine its worth and reliability.

APPLY

Apply the evidence to the patient


Using the TRAAP Test

The TRAAP Test (Timeliness, Relevance, Authority, Accuracy, Purpose) is an evaluation technique you can use to determine if the website or resource is appropriate for you to use in your research so you don’t get trapped by sources--learn how to evaluate them!. You can apply these criteria to school assignments and personal research. In the health sciences field, doctors and nurses use these same criteria to determine whether or not the information they are looking at to treat a patient is appropriate.

Digging Deeper to Evaluate Online Resources

The websites of many medical resources are designed to attract subscriptions from Medical Students. Their main pages often do not provide the information needed to critically evaluate the resource. Some online resources assume students will be surfing the web and getting anecdotal advice from other students/residents. Other denigrate the curriclum provided by Medical School and/or make claims for services with no evidence behind those claims.

You may need to dig deeper by:

  • Looking beyond the main pages to investigate pages such as FAQs and support pages.
  • Contacting the publisher/vendor for more information.
