Example: PICO(T) Question and Search Strategy

PICO(T) Question Example: 

“In adult cancer patients experiencing fatigue (P), what is the effect of meditation (I), compared with standard care (C), on quality of life (O) within 6 months (T)?”

Building a Database Search Strategy for the PICO(T) Question: 

  • A well-built PICO(T) question forms the basis of a database search strategy for finding research literature.
  • Concepts from the PICO(T) question are used to construct a comprehensive database search strategy with search terms describing each relevant component of the PICO(T).
  • Relevant elements of your PICO(T) question can be used to develop a “starter” list of keywords (including synonyms) to use in a database search. Most commonly, the most important parts of a PICO(T) question for searching are the P, I, and O.
  • After developing a “starter” list of search terms, you can then begin brainstorming your search strategy for combining terms with OR or AND, and using other techniques such as a truncation (i.e. a keyword search for letharg* will also find articles with the term lethargic or lethargy):
