State your information need as an answerable, well constructed question rather than a question that prompts a "yes" or "no" response. A clinical question should incorporate at least three elements and it is often referred to by the acronym PICO:
Patient - describe the patient as a member of a population group e.g. age, sex, ethnicity, condition, etc.
Intervention - e.g. patient education, treatment, self-care.
Comparison/Intervention - e.g. What is the main alternative to compare with the intervention? For example, do you need to decide between two therapeutic treatments?
expected Outcome - keep in mind what is the anticipated effect of the intervention on the patient.
