Patterns of eConsult use: A retrospective analysis of usage comparing two models deployed at an academic medical center.

Introduction: Electronic consultations (eConsults) have been implemented by numerous academic medical centers (AMCs) to improve communication and address access to specialty care. As these models proliferate, we must understand their comparative benefit and use in various settings.

Methods: This retrospective, descriptive analysis compares eConsult utilization trends at an AMC that has deployed an internal effort and an external pivot. Relevant metrics are presented using counts and proportions or median and range where appropriate.

Results: The internal AMC program demonstrated sustained growth from years 1 through 6, while the external pivot demonstrated considerable growth in year 1, followed by a steady decline in subsequent years. Endocrinology generated the highest number of eConsult orders in both programs (AMC 21%, external pivot 16%). Conversion rates to in-person visits were higher in the external pivot (22%) than in the internal AMC program (14%). Median response time across all specialties was faster (17 hours) for the AMC program than the external pivot (23 hours). The median number of eConsults ordered by any single primary care provider was 3 in both programs. The percentage of providers using the eConsult ordering system only once was approximately 30% in both programs. eConsults were primarily ordered by physicians (68%) at the AMC and physician assistants (40%) in the external pivot.

Discussion: The current study highlights similarities and differences between internal and external eConsult programs that can inform future "right-sizing" of care according to patient needs while promoting local care delivery and improving efficiencies at the AMC.
