Creating a well built question

Creating a Well-Built Question

Once all of the elements of the PICO format have been identified, you will need to put it together as a "Well-Built" question.

 

Example:

P:  A child under 2 years of age with otitis media.

I: Watchful Waiting

C: Amoxicillin x 10 days

O: Reducing symptoms

Well-Built Question: 

In a child under 2 years of age with otitis media, is watchful waiting versus amoxicillin x 10 days as effective in reducing symptoms.

Example:

P: A 45 year old male patient with Bell's Palsy.

I: Valacyclovir

C:  Prednisolone

O: Improving facial paralysis

In a patient with Bell's Palsy, is valacyclovir versus prednisolone more effective in improving facial paralysis?

Example:

P:  All persons entering the critical care unit

I:   Hand rubbing with a waterless, alcohol based solution

C: Hand washing with soap and water

O: Reducing nosocomial infections

For all persons entering the critical care unit, is the addition of hand rubbing with a waterless, alcohol based solution more effective than just hand washing with soap and water in reducing nosocomial infections?
