Refining and creating a well-built EBP question is often the most difficult task in the PET process. Determining what information to search for is imperative when stating the practice question (Dearholt, 24).
When forming a question out of the practice problem, consider how the pieces of unknown information relate to one another. Background Questions concern general knowledge like understanding the broad characteristics of a disease or treatment. Foreground Questions often emerge from background Questions. Foreground questions take specific knowledge from a background question area and ask for specific information to help make decisions (Straus, 15).
