Gastroenterologists and the triple aim: how to become accountable.

US medicine is fragmented and economically unsustainable and has vast opportunities for quality improvement. A current solution is to create large accountable care organizations. Fragmentation should be reduced and clinical coordination be improved, which means that gastroenterologists and other specialists will be challenged to change practices from traditional reactive and consultative care to a principal care model in which they manage appropriate clinical service lines. The pay-off in improved patient care and financial stability can be substantial. This article discusses a proposed evolution toward clinical service line management that might be achieved by an independent single specialty practice.
