Step 1: Question

Intervention (or Exposure)

The second part of formulating the question is about the intervention you are considering. An intervention can be an action you are taking to change a situation or a medical event on which you want to study the effect.

• In our first example about newly graduated registered nurses, the intervention might be baccalaureate preparation for these nurses.
• In the second example about pre-term infants, the intervention is the administration of oral sucrose by your pediatric colleague for pain management.
• In the third example, the intervention being considered by the team is the effect of a combined nurse and cardiovascular DVD approach on discharge teaching.

Questions to ask

• What medical event do you want to study the effect on?
• Ask, "What key intervention am I considering?"
