Background and aim Deploy and evaluate a gastroenterology (GI) electronic consultation (e-consult) program. E-consults are a promising approach to enhance provider communication, facilitate timely specialty advice and may replace some outpatient visits. Study As part of our health system's efforts to provide more cost-effective care under risk-based contracts, we implemented an e-consult program where referring providers submit patient-specific clinical questions electronically via an electronic referral system. A GI consultant then reviews the patient's record and provides a written recommendation back to the referring physician. For our program evaluation, we conducted chart reviews of each e-consult to understand how the program was being used and surveyed the participating providers and consultants. Results From September 2015 to March 2016, we received 144 e-consults, with most questions concerning GI symptoms or abnormal hepatology labs. Only 36% of e-consults recommended an in-person GI consult or procedure. In our survey of participating providers, referring providers strongly agreed that the GI e-consults promoted good patient care (88%) and were satisfied with the program (84%). The majority of GI consultants felt strongly that e-consults were useful for referring providers and their patients, but that current reimbursement and time allotted were not adequate. Conclusions We report on the implementation of a GI e-consult program within an ACO, showing that many clinical questions could be answered using this mechanism. E-consults in gastroenterology have the potential to reduce unnecessary visits and/or procedures for patients who can be managed by their primary provider, potentially increasing access for other patients.

Over the past decade, the role of proton pump inhibitor (PPI) medication has evolved from a diagnostic tool for Eosinophilic Esophagitis (EoE), by excluding patients with PPI responsive esophageal eosinophilia (PPI-REE), to a therapy for EoE. This transition resulted from the Updated International Consensus Diagnostic Criteria for Eosinophilic Esophagitis: Proceedings of the Appraisal of Guidelines for Research and Evaluation II (AGREE) Conference to support PPI therapy for EoE in children and adults. Additional recent advances have suggested a role for genetic variations that might impact response to PPI therapy for EoE. This review article will explore a brief background of EoE, the evolution of PPI therapy for EoE and its proposed mechanisms, efficacy and safety in children and adults, and considerations for future PPI precision medicine in patients with EoE.
