1. Formulating answerable clinical questions

A problem cannot be solved without a solution - and a solution start with a question.

It is often difficult to translate a clinical problem into a answerable question. However, it is good practice to be able to convert our information needs into answerable questions. Use the following acronym to construct an answerable clinical question: PICO

• Patient or Problem: 4 month old baby with viral bronchiolitis 
• Intervention, test or exposure of interest: corticosteroids
• Comparison interventions (if relevant): no corticosteroids
• Outcomes of interest: clinical score, length of hospital stay
