Evaluating Web Resources for Reliable Medical Information: Best Practices and Tips

The web can be a valuable tool for finding medical and health resources, but it is crucial to evaluate websites for credibility. Key factors to consider include authority, accuracy, objectivity, currency, and purpose. Not all online content is trustworthy—verify authorship, check for grammatical errors, assess potential biases, and ensure the site is up-to-date. Utilize reputable databases for evidence-based practice (EBP), such as Cochrane, CINAHL, and MEDLINE. Your growing professional knowledge is essential in discerning credible resources.

  1. nU 420Information Literacy session Using Reliable Resources

  2. Question: Should the web be used to find medical/health resources?

  3. Answer: Yes, however….

  4. Websites must be evaluated to verify • Authority • Accuracy • Objectivity • Currency • Purpose

  5. Question: Why is verification important?

  6. Answer: • Because not all information on the web is • Equal • Accurate • Created by an expert • Intended as authoritative

  7. Web Evaluation Criteria

  8. Authority: • Are you able to identify the author? Can you verify the author is an expert in the field being researched? • If an author is not cited, is the site sponsored by a well known and well regarded organization or agency? • Is the site found in a reliable domain (.edu, .gov, .org)? • Can you find any trustworthy reviews of the site?

  9. Accuracy • Is the writing sound? Do you see typing, spelling or grammatical errors? • Is there a list of references? Do the sources in the reference list seem scholarly? Is an original source for the information cited? • Can you verify the information in another reliable source? • If disclaimers are used, what is the nature of their warning?

  10. Objectivity • Is there any reason to suspect bias? • Are links to other sites provided? If so, do they indicate potential bias?

  11. Currency • When was the site created? • When was the site last updated? • If links are provided on the page, do they point to live, updated sites?

  12. Purpose • For whom is the site intended? • What is the main objective of the site?

  13. Remember, the best tool you bring to web resource evaluation is your growing professional knowledge in the field of nursing. Do not be afraid to rely on that knowledge when rejecting resources that seem to “pass” a criteria-based evaluation, and do not hesitate to include resources when you can confirm their accuracy and usefulness.

  15. Three Tips of Finding EBP in SJC Databases

  16. Tip 1: • Search appropriate databases: • Cochrane Database of Systematic Review • CINAHL • MEDLINE

  17. Tip 2: Check database controlled vocabulary when in doubt. CINAHL and MEDLINE use specific subject heading that do not always match our own vocabulary. Blood pressure = hypertension

  18. Tip 3: Limiters function differently when performing simultaneous searching. Not all databases respond to the same limiters.

  19. CINAHL’s Evidence-Based Practice limiter yields articles with general studies into the use of EBP, not the practices themselves. Use the “Systematic Review” Publication Type instead.
