The impact on the elapsed time to care and outcomes of a clinician-to-clinician electronic consultation program in patients diagnosed or suspected atrial fibrillation in primary care

Abstract Background An early diagnosis and early initiation of oral anticoagulants (OAC) are main determinants for outcomes in patients with atrial fibrillation (AF). Clinician-to-clinician electronic consultations (e-consultations) program as the first step in the ambulatory care organization for the general practitioner (GPs) referrals to cardiologist may improve health care access by reducing the elapsed time for cardiology care compared with a face-to-face consultation for all the referrals. Objective To evaluate the effect on outcomes of a reduced elapsed time to care after a clinician-to-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 referred by general care practitioners for cardiology consultation with confirmed or suspected AF from 1 January 2010, to 31 December 2019. Until 2012, all patients were attended with 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 clinical comment and 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) (Figure 1, A), and an increase of OAC use (61% [95% IC: 19.6%–102.4%], p < .001) (Figure 1, B). 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]) (Figure 2). Conclusion A shared EPD-based clinician-to-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, cardiovascular and all-cause mortality.
