Evidence-based nursing is a process founded on the collection, interpretation, appraisal, and integration of valid, clinically significant, and applicable research. It is not about developing new knowledge or validating existing knowledge, but rather translating existing evidence so that it can be applied to clinical decision making. This process starts with formulating a sound PICO question. PICO is a format for developing a good clinical research question prior to starting a review or research. It is a mnemonic used to describe the four elements of a sound clinical foreground question.
