Electronic Consultations in Allergy/Immunology

Abstract

Background: Allergic condition management more often requires allergist guidance than allergy testing; necessary testing may be unavailable at initial drug allergy consultations. Electronic consultations (e-consults) provide expedited, problem-focused, potentially cost-saving care in other medical specialties, but have not yet been studied in Allergy/Immunology.

Objective: To describe e-consult use at an academic allergy/immunology practice.

Methods: E-consult data (August 10, 2016 through July 31, 2018) and in-person consult data (August 1, 2014 through July 31, 2018) were reviewed to determine consult volume, outcomes, indications, and timing. Referral reasons and wait times were compared with chi-square tests.

Results: E-consults grew from 1% to 10% of all new consults, with concurrent growth in in-person consults. Of 306 completed e-consults, 41 (13.4%) made diagnostic, therapeutic, or alternative referral recommendations, with 30 (73%) recommendations followed; 183 (59.8%) patients required an in-person Allergy/Immunology consult, and only 5 (<2%) patients saw an allergist without an e-consult recommendation to do so. E-consults were used more often than in-person consults for adverse drug reactions (66% vs 9%; P < .001), especially penicillin allergy (132, 61% of all e-consults) and immunodeficiency (15% vs 2%; P < .001). Allergists completed e-consults in a median of 11 minutes, with a median turnaround time of 22 hours. E-consult implementation was associated with a decreased median in-person consult wait time (1.5 fewer calendar days; P < .05).

Conclusions: E-consults were increasingly used, particularly for historical adverse drug reactions and immunodeficiency. Implementation of an e-consult program resulted in decreased in-person wait times despite an increase in overall consult volume, supporting this model's ability to provide expedited, problem-focused care.
