"Research is conducted according to the researcher’s intention, their purpose, and the paradigm they’re operating from within. While many people use the word “research” to loosely mean “gathering information” scientists use this word in a more specific way.
PICO is a mnemonic used to aide the clinician or researcher in identifying the important parts of a well-defined clinical question. This question then provides the basis for a search of medical literature on the question topic.
Literature searching is the systematic review of published articles, data, books and reviews. Sometimes referred to as "evidence", this process is carried out with the intention of supporting or disproving a query.
Evidence based practice (EBP) includes literature searching in response to identified clinical or practice based questions. It is important that researchers understand the characteristics of the databases within which they are searching. Scholarly, peer-reviewed articles and quality research manuscripts can be found in databases organized and indexed using biomedical terminology and medical subject headings [MeSH].
