Abstract 13412: Electronic Consultation for the Management of Atrial Fibrillation is Associated With Higher Healthcare Costs

Introduction: A study of 42,000 cardiology consults within the Veterans Health Administration (VHA) in 2016 found that patients who received electronic consultation (e-consults) had similar healthcare costs at 6 months compared to those who received face-to-face (F2F) consults. However, results may have been confounded if patients with less costly conditions received e-consults. Our aim was to compare costs between those receiving F2F vs. e-consults for a similar indication. Hypothesis: Electronic rather than F2F consultation for atrial fibrillation (AF) management will be associated with lower total healthcare costs. Methods: We conducted a retrospective cohort study of a national sample of VHA patients who received cardiology consultation in 2016. We used a natural language processing script to identify consults for AF management. Primary outcomes were total healthcare costs at 3 and 6 months. Secondary outcomes included inpatient and outpatient costs. We compared costs between groups using a generalized linear model with a gamma distribution and log link. We adjusted for community wage and Charlson comorbidity indices, distance to nearest facility, age, and gender. Standard errors were clustered at the facility level. Results: We sampled 176 F2F and 136 e-consults from 43 facilities. Mean total 6-month costs were $12,928 (95% confidence interval [CI]: 1,377; 40,644) and $8,286 (95% CI: 959; 31,320) among e-consult and F2F groups, respectively. The e-consult group had 12.3% higher 3-month (p Conclusions: Use of e-consults for AF management is associated with reduced inpatient costs at 3 months, but higher total costs, which were largely driven by outpatient costs. Improving our understanding of healthcare utilization after initial consultation, or in differences in reasons for consultation within AF management may help explain these differences.
