Assessment of the value of gastroenterologists' activity in the outpatient setting: applying the "Moneyball" approach to clinical care.

Background: With the emergence of alternative payment systems replacing the traditional funding models, the value of physician activity is scrutinized more closely. Attempts have been made to quantify the value of endoscopists' activity; there is little in the medical literature describing gastroenterologists' value in the outpatient setting.

Aims: To characterize the value of clinical activity of gastroenterologists in the outpatient setting.
