Primary and Secondary Literature

Primary Literature: 
Primary literature for scientists means this is the first publication of original research in journals, conference proceedings, magazines, and other sources.  Primary literature is the original work on which other works are based and usually shares new knowledge, findings, or results in its original form without interpretation by other writers.   Expect to see the following sections:

  • Methods (population, materials. instruments)
  • Results (with charts, graphs, etc.)
  • Discussion

The abstract will probably include a phrase like “in this study” or something similar.  Articles will be very scholarly and appear in academic journals.


Secondary Literature:

Are the works based on primary literature that usually include interpretation or commeimage of review articlentary by other writers or scholars not involved in the original research.  Reviews of Literature are an example of Secondary Literature.

  • Review article:​  Author analyzes and summarizes all of the existing original research by others on a broad topic.  The title may include the phrase “literature review” or sometimes just “review.”    Articles will be scholarly and appear in academic journals.
  • News: ​Author summarizes recent research for a general or lay audience.image of news article

Evidence-Based Practice

ASHA

The goal of EBP is the integration of: (a) clinical expertise/expert opinion, (b) external scientific evidence, and (c) client/patient/caregiver perspectives to provide high-quality services reflecting the interests, values, needs, and choices of the individuals we serve. Conceptually, the trilateral principles forming the bases for EBP can be represented through a simple figure.

The question above includes the PICO elements:

P (Problem or Patient or Population): hospital acquired infection

I (Intervention or Indicator): hand washing

C (Comparison): no hand washing; other solution; masks
