The key to finding appropriate evidence is to ask a searchable, answerable question. The PICO framework is often used as a guide for asking clinical questions.
|P = patient, problem, population|
|I = intervention|
|C = comparison intervention, control|
|O = outcome(s)|
Have you noticed resources that refer to PICOT instead of PICO? Some EBP experts add T to the standard PICO framework. The T usually stands for time and can be helpful in making sure you're thinking of the appropriate time frame for your intervention and/or outcomes.
