PICOT Questions

PICOT Questions for nursing research

PICOT is an acronym to help you formulate a clinical question and guide your search for evidence. Using this format can help you find the best evidence available in a quicker, more efficient manner.  Therefore, the PICOT question format is a consistent “formula” for developing answerable, researchable questions. When you write a good one, it makes the rest of the process of finding and evaluating evidence much more straightforward.

P: Population/patient – age, gender, ethnicity, individuals with a certain disorder

I: Intervention/indicator (Variable of Interest) – exposure to a disease, risk behavior, prognostic factor

C: Comparison/control – could be a placebo or “business as usual” as in no disease, absence of risk factor, Prognostic factor B

O: Outcome – risk of disease, accuracy of a diagnosis, rate of occurrence of adverse outcome

T: Time – the time it takes for the intervention to achieve an outcome or how long participants are observed

Examples of Evidence-Based PICOT Questions

 PICOT Question:

Population: Bariatric adolescents considering or undergoing gastric bypass surgery.

Intervention: The nurse’s role as a primary member of the multidisciplinary team regarding perioperative care of the bariatric adolescent patient.

Comparison: The nurse’s role as a secondary member of the multidisciplinary team without any specialized training and is only involved in perioperative care of the bariatric adolescent patient.

Outcome: When the nurse is involved as one of the primary members in the multidisciplinary team approach, the bariatric adolescent patient has better continuity of care.

Time: perioperative including the 6 weeks post recovery.

PICOT Question: Does the bariatric adolescent patient undergoing gastric bypass have better continuity of care perioperatively and postoperatively when the nurse is a primary member of the multidisciplinary team versus when the nurse is a secondary member whose only role is in providing perioperative care and has no specialized training?
