Evidence based practice defines 'research' as the creation of new knowledge through studies or trials.  (Some folks include surveys and questionnaires.  See Types of research.)   You could think of this as Research with a capital R.

Looking up studies and trials is defined as a 'literature review'.  You could think of this as research with a small 'r'.  It is what we do when we want to find out what is already known.

When practicing evidence based nursing, you usually have to perform a literature review.  You seldom actually have to 'do' Research.

2.  You clarify your question using PICO. 

P=patient/problem   I=intervention   C=comparison  O=outcomes

3.  You search for an existing answer in research studies or summaries 

4.  You evaluate the answer that you find - does it fit with your patient's values and with the resources at hand?

5.  You carry out the answer
