Abstract only Introduction: Excessive alcohol consumption has been associated with increased risk of cardiovascular (CV) disease. Hypertension (HTN) is a known risk factor for CV disease, in general, including congestive heart failure (CHF). Healthcare resource utilization (HRU) and costs associated with comorbid alcohol use disorder (AUD) among patients with HTN or CHF were evaluated. Methods: This retrospective cohort study identified adults with moderate-to-severe AUD from patients with ≥1 inpatient, or ≥2 outpatient claims on separate days, for HTN or CHF (MarketScan® and Medicare [1/1/2016-12/31/2020], Medicaid [1/1/2016-12/31/2019] databases), and ≥1 year of continuous healthcare enrollment prior to diagnosis (baseline) and 3 months after. Monthly HRU and costs were compared between propensity-score matched patients based on AUD presence using rate ratios in generalized linear models. Results: Of 4,015,785 patients with HTN, 1% were diagnosed with AUD. Use of HTN pharmacotherapy was similar for all patients, except for less frequent use of angiotensin receptor blockers (ARBs) in those with AUD. HTN patients with comorbid AUD had a higher risk of inpatient visits (89%), ED visits (39%), longer inpatient stays (98%), and outpatient visits (9%) relative to non-AUD patients. Of 294,892 patients with CHF, 2% had comorbid AUD. CHF pharmacotherapy use was similar for all patients, except for less frequent ARB use in those with AUD. CHF with comorbid AUD had a higher risk of inpatient visits (31%), ED visits (25%), and longer inpatient stays (34%) relative to non-AUD patients. Outpatient visits were 5% lower in CHF patients with AUD. AUD was associated with higher acute care costs, fewer pharmacy claims, and lower pharmacy costs in both HTN and CHF cohorts. Patients with AUD in both cohorts were more likely to be younger, male, enrolled in Medicaid, with a higher comorbidity burden. Conclusion: In this real-world study, the presence of AUD in patients with either HTN or CHF was associated with greater comorbidity burden, higher acute care utilization and costs, and lower outpatient pharmacy utilization relative to patients without AUD. These findings suggest that AUD impacts care for both HTN and CHF, which could be an opportunity for improved screening and treatment.
