What does the acronym PICO stand for in clinical question development?

The acronym PICO stands for Patient Intervention Comparison Outcome and is a widely recognized framework used in evidence-based practice to formulate clinical questions. This structured approach helps to clarify the components of a research question, making it easier for clinicians to focus their inquiry on specific patient populations, types of interventions, potential comparisons with other treatments, and the outcomes of interest.

The first component, "Patient," emphasizes the specific group or individual whose health condition or population you are addressing. "Intervention" refers to the treatment or intervention being considered, which could be a specific medication, therapy, or procedure. "Comparison" is about identifying any alternative interventions against which the primary intervention will be evaluated, whether it's a placebo, another treatment, or no treatment at all. Lastly, "Outcome" pertains to the effects or changes that the intervention aims to achieve, such as improvements in health status, symptom relief, or quality of life. This structured approach enhances clarity and focus in clinical inquiry, ultimately contributing to better outcomes in patient care.
