The impact of inter-clinician electronic consultation in patients diagnosed with atrial fibrillation in primary care.

Background: An early diagnosis and early initiation of oral anticoagulants (OAC) are main determinants for outcomes in patients with atrial fibrillation (AF). Inter-clinician electronic consultations (e-consultations) program for the general practitioner referrals to cardiologist may improve health care access by reducing the elapsed time for cardiology care.

Objective: To evaluate the effect of a reduced elapsed time to care after a inter-clinician e-consultations program implementation (2013-2019) in comparison with previous in-person consultation (2010-2012) in the outpatient health care management in a Cardiology Department.

Methodology: We included 10,488 patients with AF from 1 January 2010, to 31 December 2019. Until 2012, all patients attended an in-person consultation (2010-2012). In 2013, we instituted an e-consult program (2013-2019) for all primary care referrals to cardiologists that preceded patient's in-person consultation when considered. The shared electronic patient dossier (EPD) was available between GP and cardiologist, and any change in therapy advice from cardiologist was directly implemented in this EPD.

Results: During the e-consultation period (2013-2019) were referred 6627 patients by GPs to cardiology versus 3861 during the in-person consultation (2010-2012). The e-consultation implementation was associated with a reduction in the elapsed time to anticoagulation prescription (177.6 ± 8.9 vs. 22.5 ± 8.1 days, p < .001), and an increase of OAC use (61% [95% IC: 19.6%-102.4%], p < .001). The e-consult program implementation was associated with a reduction in the 1-year CV mortality (.48 [95% CI: .30-.75]) and all-cause mortality (.42 [95% CI: .29-.62]). The OAC reduces the stroke mortality (.15 [95% CI: .06-.39]) and CV mortality (.43 [95% CI: .29-.62]) and all-cause mortality (.23 [95% CI: .17-.31]).

Conclusion: A shared EPD-based inter-clinician e-consultation program significantly reduced the elapsed time for cardiology consultation and initiation of OAC. The implementation of this program was associated with a lower risk of stroke and cardiovascular/all-cause mortality.
