 This study aims to determine if unhealthy alcohol use, UAU, is associated with more severe clinical presentation and worse health outcomes related to COVID-19 in patients who tested positive for SARS, COV, two-vionazopharyngeal swab or had two COVID-19 international classification of disease, 10th revision, ICD, 10 codes. The study used a digital machine learning classifier on electronic health records to identify patients with UAU, and then performed a multivariable regression to examine the relationship between UAU and COVID-19 severity as measured by hospital care level. Results showed that each incremental increase in the predicted probability from the digital alcohol classifier was associated with a greater odds risk for more severe COVID-19 disease, and patients in the unhealthy alcohol group had a greater odds risk to develop more severe disease. The study concluded that UAU is an independent risk factor associated with greater disease severity and or death in patients infected with SARS, COV, two.
