Building Clinical Questions with PICO(T)

The PICO(T) format can help you develop a clear, answerable research question and decide what type of evidence you are looking for. The templates below can help you form a research question (note that not every question may contain all PICO(T) elements).  

 

Some sample PICO templates:

For an intervention or therapy:

In _______(P), what is the effect of _______(I) on ______(O) compared with _______(C), within ________ (T)?

 

For a diagnosis or diagnostic test:

Are (is) _________ (I) more accurate in diagnosing ________ (P) compared with ______ (C) for _______ (O)?

 

For prevention questions:

For ________ (P) does the use of ______ (I) reduce the future risk of ________ (O) compared with _________ (C)?
