The success of obtaining answers in any research project relies on how well the investigators are able to ask the right question. The PICO (Patient, Intervention, Comparator, Outcomes) approach provides a framework to develop this question utilizing four major elements: Population, Intervention, Comparison, Outcomes. This paper provides a framework for both the young and the experienced surgeon in the use of the PICO approach to construct a clear research question.
