PICO is a mnemonic used to help you clarify your clinical question. It acts as a framework, asking you to think specifically about different aspects of what you want to investigate. As you build your PICO, you should make sure that you are clear and specific about what you are looking for. This helps you target the right evidence to use in practice.
In some questions, a T is added to the PICO framwork as well to help find a specific level of evidence.
P: Patient, Problem, or Population
T: Timeframe, Type of Study, or Type of Question
Be sure to make your question specific. What type of patient are you looking for? Are you using a specific test as your intervention, or a broad group? If you are looking for better outcomes, what are examples of those outcomes?
A good clinical question will address most, if not all, parts of the PICO framework. A good PICO will be specific and define terms and outcomes if necessary. A good PICO will investigate something new in terms of diagnosis, etiology, therapy, harm, etc.
A bad PICO is usually a background question disguised as a research question. For example, "what are the effects of Prilosec on patients taking immune suppressants" might seem like a good research question, but it is not. First, effects of a drug are often considered background information because you can look up this information in a drug monograph- you don't need an article to tell you this. Second, the question is very vague. What immune suppressant are you looking at? What are the characteristics of your population? You need more details to make this a question worth researching.
It may seem tempting to pick a very specific PICO question, but remember, for many nursing school assignments, you need to find existing literature. If you can't locate articles about your PICO topic, try searching for one or two components first instead of all of them at once. Some articles many cover one part of your PICO and other articles may cover other parts of it. You need to build your case and explain the research that is out there, so it is alright if your articles don't 100% match your entire PICO question.
Try words from your topic in these templates. Your PICO should fit only one type of question in the list.
