Public health nurses need efficient ways to locate trustworthy research and interventions. This lesson introduces databases, registries, and other evidence resources, and explains how a PICOT question can guide a focused search.
A database is a systematically organized collection of information. Databases help narrow the large body of published research to sources relevant to a question. A clearly defined PICOT question—which identifies the population, intervention, comparison, outcome, and time—helps determine search terms and which database may be most useful.
