Defining a clinical question in terms of the specific patient problem aids the searcher in finding clinically relevant evidence in the literature.
The PICO Model is a format to help define your question.
|Patient, Population, or Problem
|How would I describe a group of patients similar to mine?
|Intervention, Prognostic Factor, or Exposure
|Which main intervention, prognostic factor, or exposure am I considering?
|Comparison or Intvervention (if appropriate)
|What is the main alternative to compare with the intervention?
|Outcome you would like to measure or achieve
|What can I hope to accomplish, measure, improve, or affect?
The Centers for Disease Control and Prevention (CDC) publish several journals that may be helpful in your search for evidence.
The CDC is also an excellent resource for statistics on U.S. health.
Open access (OA) refers to freely available, digital, online information. Open access scholarly literature is free of charge and often carries less restrictive copyright and licensing barriers than traditionally published works, for both the users and the authors. The following links will allow you to search open access materials available from libraries, governmental resources, etc.
Your organization may subscribe to one or more of the Nursing Evidence resources:

How do you get full text articles? Start with your nearest library. If your employer / organization does not have a library:
