How to use outcomes questionnaires: pearls and pitfalls.

Patient-reported outcomes serve as an essential and perhaps more relevant means for assessing patients' response to treatment than clinical measures alone.

Surgeons need to possess knowledge and skills about outcomes assessments and understand how to apply them to improve quality of care delivered based on evidence. This article discusses the appropriate use of outcome questionnaires to rigorously evaluate treatment methods based on patient satisfaction and the outcome measurement instruments frequently used in plastic surgery.
