E-consults between primary care and internal medicine: implementation, accessibility, benefits, and implications

Aim

This work aims to evaluate whether electronic consultations (e-consults) are a clinically useful, safe tool for assessing patients between primary care and internal medicine.

Methods

This is a retrospective cohort study of all e-consults ordered by the Primary Care Department to the Internal Medicine Department between September 2019 and December 2023. The results of initial consultations, emergency department visits and subsequent admissions, and survival were assessed and complaints and claims filed were reviewed.

Results

A total of 11,434 e-consults were recorded (55.4% women) with a mean age of 62.1 (SD19.4) years and a wide range (15–102 years). The mean response time was 2.55 (SD 1.6) days. As a result of the e-consults, 5645 patients (49.4%) were given an in-person appointment. For the remaining 5789 (50.6%), a written response was provided. Among those given appointments, the time between the response and in-person appointment was less than five days (95% of cases). Compared to those not given appointments, in-person appointments were older (p < 0.0001), visited the emergency department more times (one month: p = 0.04; three months: p = 0.001), were admitted to the hospital more times (one month: p = 0.0001; three months: p = 0.0001), and had higher mortality at one year (12.7% vs. 9.8% p = 0.0001). In the Cox analysis, only in-person appointments (RR = 1.11; p = 0.04)) and age (RR = 1.09; p < 0.01) were independent factors of mortality. No complaints or claims of any kind were registered.

Conclusions

These data suggest that e-consults are a clinically useful, safe tool for assessing patients referred from primary care to internal medicine departments.
