Evidence-Based Practice in Communication Disorders

EBP logo


'The goal of EBP is the integration of clinical expertise/expert opinion, external scientific evidence, and client/patient/caregiver perspectives to provide high-quality services reflecting the interests, values, needs, and choices of the individuals we serve.'  (ASHA)

Or as D. Sackett states more simply, "Evidence-based medicine is the integration of best research evidence with clinical expertise and patient values."

For more information about EBP in Communication Disorders as well as an abundance of resources, go to: 

In addition to ASHA's resources, please see the list below for recommended databases for EBP research available via MU Libraries.

Database Research Tips

Remember these Research Tips highlighted above: 

When using EBSCO's CINAHL Complete database, you can limit your results before you search by going to the Advanced Search page and checking the box next to evidence-based practice in the Limiters section.  (You can also do this after the search by using Limit To tools in the Refine Results section in the left column of your results screen.)

When using ProQuest's Nursing & Allied Health database, you can limit your results in a similar manner by going to the Advanced Search page, scrolling down to the Document Type box in the Search Options section and selecting Evidence Based Healthcare.

When using MEDLINE (any platform), you have the option of limiting results to "publication," "document" or "article" type depending on the platform you are using.  In this way, you can choose to limit results to clinical trials, systematic reviews, case reports, comparative studies or meta-analysis, for example.
