According to Johns Hopkins Medicine's Center for Nursing Inquiry, Evidence-Based Practice (EBP) "is a process used to review, analyze, and translate the latest scientific evidence. The goal is to quickly incorporate the best available research, along with clinical experience and patient preference, into clinical practice, so nurses can make informed patient-care decisions (Dang et al., 2022). EBP is the cornerstone of clinical practice. Integrating EBP into your nursing practice improves quality of care and patient outcomes" ("Evidence-Based Practice," n.d.)
Evidence-based practice involves framing a question, locating, assessing, evaluating, and repeating as needed. Using PICO(T) can help write a focused clinical question. The following table describes the different parts of PICO(T).
Note: Please consult your professor when formulating PICO(T) questions. The information on this page is only meant to serve as a guide.

Who are the relevant patients? Think about age, sex, location, or specific characteristics that would be important to your question. | What is the strategy, medication, procedure, diagnostic test, or exposure? | What is the control or alternative you would like to compare to the intervention or indicator? | What are the patient-relevant consequences of the intervention? Consider both patient-oriented outcomes (morbidity, quality of life, etc.) and surrogate outcomes (lab values, test characteristics, etc.) | What time periods should be considered? What study designs are most likely to have the information you hope to find? What clinical domain does your question fall under? |
There are many ways to formulate your PICO question. You may find it helpful to use one of the following formats:
In _________ (P), how does _________ (I) compared to _________(C) affect _______(O) within _______ (T)?
In _______(P), what is the effect of _______(I) on ______(O) compared with _______(C) within ________ (T)?
In ________ (P) are/is ________(I) compared with ________(C) more accurate in diagnosing ________(O)?
Are ____ (P) who have _______ (I) at ___ (Increased/decreased) risk for/of_______ (O) compared with ______ (P) with/without ______ (C) over _____ (T)?
In _______(P), what is the effect of _______(I) on ______(O) compared with _______(C) within ________ (T)?

Students have many questions about evaluating Evidence-Based Practice (EBP) resources and PICO(T) questions, and FDU librarians are happy to provide guidance. We can assist by helping you find articles in a database and guide you towards relevant resources. If you need help creating PICO(T) questions or determining whether an article involves EBP, please contact your professor, the Academic Support Center, or the Metro Writing Studio for help.
