Feedback:
A crucial first step in evidence-based practice (EBP) involves asking relevant clinical questions that reflect uncertainties in clinical practice. Most guidelines for EBP use the acronyms PIO or PICO to help practitioners develop well-worded questions that facilitate a search for evidence. In the acronym PIO, the P stands for population or patients; the I stands for intervention; and the O stands for outcome. The acronym PICO includes these same three components plus a fourth, C, which stands for comparison.
