Evidence-Based Healthcare

Using the PICO formula helps you build an answerable question:

Example:

• Patient: Teenagers with cancer
• Intervention: Standard care
• Comparison: Listening to tranquil music, or audiotaped comedy routines
• Outcome: Reduced levels of reported anxiety

This becomes the Clinical Question:

In teenagers with cancer, does listening to tranquil music or audiotaped comedy routines do a better job of reducing levels of reported anxiety than standard care?
