Framing the Research Question
The first part of any research is identifying the question you want to answer. This is very important because the more you understand your question the more likely you are to obtain relevant results. One way of building your search question starts with the patient and is known as PICO, which stands for:
P - Patient or Population or Problem/Disease
Who or what is the question about? This may include the primary problem, disease, or circumstances.
I - Intervention, Exposure or Prognostic Factor
What main intervention/treatment are you considering?
C - Comparison(s) (optional)
What alternative intervention are you considering, if any? For example, you might be comparing the efficacy of two medications or the accuracy of two diagnostic tests. Your clinical question does not have to always have a specific comparison.
O - Outcome(s)
What are you trying to accomplish or measure? What are you trying to do for the patient or problem? Examples might include managing a disease, alleviating symptoms, preventing a disease, etc.
Organizing Your Literature
After your search the journal literature you will need to collect and organize your references. The easiest way to do this is by using a citation manager with MS Word.
These tools allow you to:
- Store citation information online
- Format in-text citations for your papers
- Create a bibliography
