Nursing relies on Evidence Based Practice (EBP) to inform practitioners on the best course of action. PICO helps to clarify and define the research need, as well as to focus on the comprehensive care of the population.
When researching topics remember to include PICO elements:
P= Population. Who requires treatment? Think about demographics such as age, gender, ethnicity, or medical condition.
I= Intervention. How should the population, or patient, be treated? This does not necessarily have to be an action. Intervention could be in the form of exposure or even the patient's perception.
C= Comparison. This element is optional. Are studies or trials of alternative interventions available, with which to compare your population and intervention?
O= Outcome. What is the desired result of intervention on the population? This statement must be specific in order to determine the result.
The Cochrane Library is a collection of databases that contain different types of high-quality, independent evidence to inform healthcare decision-making (assessment, reviews, controlled trials register, etc.).
