PICO(T) Research Overview

PICO(T) Research in 5 minutes:

  1. Creating a PICO Question
  2. Formulating a Research Strategy
  3. Locating the best Evidence

Effectiveness Questions: PICO(T)

P = Population / Patient / Problem: Group of people or issue of concern 
I = Intervention: Treatment or action taken 
C = Comparison / Control:  A different intervention OR control group (usual care / no intervention)
O = Outcome: Specific effect(s) of the intervention or what matters to the nurse and patient
T = Timeframe (if applicable)

Meaningfulness Questions: PICo(T)

P = Population: The group of people that are of concern in the question
I = Phenomenon of Interest: Events or experiences being studied 
Co = Context: Primary conditions and background circumstances involved
T = Timeframe (if applicable)

PICO(T) Question Tips & Templates

Tips & Reminders for Writing PICO Questions:

  • PICO(T) questions do not have to be written in P-I-C-O order. 
  • Time (T) is optional for PICO questions; use T if a specific timeframe limitation will help you answer your PICO question.
  • Comparison is not required for PICO(T) questions; if you are comparing an intervention or phenomenon with usual care or a control group, e.g. comparing intervention vs. no intervention taken, you do not have to include a Comparison element in the question unless it improves clarity.
  • If you are Comparing two different interventions, these are your primary variables for the study and as such they need to be related and measurable against each other. Using the scientific method, you want to make sure you are comparing "apples to apples" in order for your conclusions to be valid and unbiased.
