INTRODUCTION SARS-CoV2, the virus responsible for the COVID-19 pandemic, 1 has forced rapid changes in healthcare delivery. Telehealth has previously played a role in delivering ambulatory care in the setting of similar disasters. 2 Electronic consultations (e-consults), in particular, may be an effective method of sustaining specialty consultative care while preserving social distancing and reducing demands for personal protective equipment. Hypothesizing that e-consult requests would increase during the pandemic, we sought to define COVID-19associated changes in e-consult requests.

METHODS e-Consults are asynchronous clinician-to-clinician exchanges that rely on information in the patient's electronic health record (EHR). Requesting clinicians ask specific clinical questions; specialist physicians review the patient's EHR and document detailed recommendations as an EHR note ( Fig. 1 ). Our institution, which first implemented e-consults as pilot programs in Cardiology and Dermatology, 3 has completed over 35,000 e-consults in 50 subspecialty areas and extensively studied their use. 4 Our primary outcome was e-consult proportion, defined as e-consult volume over total consult volume (e-consult volume plus traditional ambulatory consult volume). We used an interrupted time series (IST) model to assess the effect of the pandemic on e-consult proportion. We assessed daily volumes from February 1, 2020, through April 1, 2020; the defined date of "intervention" was March 11, 2020, when Massachusetts declared a COVID-19-related state of emergency. We included weekend/holiday as a covariate to account for differences in consult requests between business days and weekends. We excluded specialty areas with less than 20 e-consult requests, specialty areas that did not offer both an active e-consult and ambulatory consult option, and psychiatry as it included some requests for behavioral health resources without a need for specialist guidance.

This work, performed for administrative purposes, was exempt from review by the Partners Healthcare Institutional Review Board (IRB) per the IRB's policies. Statistical analysis was performed using SAS, version 9.4 (SAS Institute, Inc., Cary, NC).

Before March 11, 2020 (n = 40 days), a median of 565 ambulatory consults and 48 e-consults were requested daily. After March 11, 2020 (n = 21 days), a median of 144 ambulatory consults and 40 e-consults were requested daily. While both types of consult requests declined after March 11, the ambulatory consults declined more than the e-consults resulting in an increase in absolute e-consult proportion from 8.5 to 19.6%. After adjusting for weekend and secular trend, we found e-consult proportion increased by 5% (95% CI 2-7%) daily from pre-emergency declaration levels (Fig. 2) .

We describe a significant increase in e-consult utilization relative to traditional ambulatory referrals following the COVID-19-related state of emergency declaration in Massachusetts. Our results suggest that e-consults can provide a mechanism for sustaining outpatient consultative care during this pandemic.

Study limitations include the fact that these results obtained from a single Boston-based academic medical center may not be generalizable, particularly to institutions without a strong econsult program in place. Additionally, this study design cannot assess the relative effectiveness of e-consults versus other types of virtual and in-person care delivery mechanisms.

These results suggest an increase in e-consult utilization associated with the COVID-19 pandemic in the USA. e-Consults may be a promising method of ambulatory consultative care delivery as they can potentially replace some specialty consultations in a manner that provides clinical guidance while reducing the risk of in-person visits to both patients and physicians. This question is electronically transmitted to a specialist physician who reviews the question and clinical information in the EHR and provides clinical guidance including recommendations for further diagnostic testing or therapeutic management via a note entered in the patient's EHR.

The referring clinician reviews the specialist's recommendations and orders necessary testing or therapies. obtained prior to this date; points to the right represent data obtained after this date. Tick marks refer to the number of days in either direction. A linear model was fitted to the pre-and post-intervention data to better demonstrate the changing trend in e-consult proportion over time.
