Mid-level providers in gastroenterology.

One response to the challenges of modern day clinical practice has been to employ "mid-level providers" (MLPs), such as physician assistants and nurse practitioners. MLPs may complement physicians by supporting patient self-management and performing routine, protocol-guided management. In turn, MLPs may improve health outcomes and simultaneously lower costs. Within gastroenterology, the prevalence of MLPs remains unknown, though it appears to be significant and increasing. Additionally, professional organizations predict that in the future, MLPs will play a central role in digestive disease care. Although incorporating MLPs into gastroenterology has great potential, numerous challenges exist, and their specific roles must first be defined and evaluated.
