NUR 3165: Evidence-Based Nursing Practice: ASK: Use PICO to Create Research Question

PICO

PICO is a mnemonic used to describe the elements of a clinical question. Once a well-structured question is formulated, you will be in a better position to search the literature. 

P - Patient/Problem 
Age? Sex? Race? Conditions? Primary Complaint?

 

I - Intervention
What will you do for this patient? A diagnostic test? A treatment? A therapy? Medication?

 

C - Comparison/Control (if relevant)
Is there a control or alternative management strategy you would like to compare to the intervention or indicator?

 

O - Outcomes
What results do you want to see? Preventing conditions? Relieving symptoms? Decreasing discomfort?

  ------------------------------------------------------------------------------------------------

T - Time/Type of Study (if applicable)

What time periods should be considered?  What study types are most likely to have the information you seek?

P - Accidental falls
I - Video monitoring
C - (Sitters; Rounds; Fall alarms)
O - Reduce/Prevent falls 
Clinical Research Question: Is video monitoring an effective tool for reducing accidental falls? Is video monitoring more effective than fall alarms in reducing accidental falls? 

 

P - Hypertension
I - Self-monitoring
C - Telemonitoring
O - Better management
Clinical Research Question: Does self-monitoring with telemonitoring lead to better management of hypertension? 

 

P - Children with the flu
I - Tamiflu
C - Over-the-counter medications
O - Reduce hospitalizations
T  -  Administered within the first 48 hours of symptoms
Clinical Research Question: Is Tamiflu more effective than over-the-counter medications in reducing childhood hospitalizations due to the flu if administered in the first 48 hours of the onset of symptoms?
