PICO is one type of framework to develop an evidence based practice literature search strategies.

The acronym stands for:

P - Patient, Problem, or Population (What is the condition or disease?)

I - Intervention (What do you want to do with this patient?)

By using this framework you are able to structure a well-formed clinical search question.

You can also consider alternatives to PICO. including SPIDER, COPES, ECLIPSE, PIPOH, PECODR etc) based on field of study (eg: medicine, OT, social work, speech pathology, oncology etc).
