A, Overall association of AUD with outcomes of hospitalization for community-acquired pneumonia. B, Association of AUD with outcomes of hospitalization for community-acquired pneumonia stratified by presence of alcohol withdrawal syndrome (AWS). Late intensive care unit (ICU) admission, late invasive mechanical ventilation (IMV), and late vasopressor use were defined as arising on day 2 or later and were studied only among patients for whom the respective late outcome was not present earlier. Costs were studied conditionally only among patients with positive costs and from hospitals with greater than 50% of all patients also with positive costs. Patients with no cost were excluded. Reduced models were adjusted for age, sex, race, and insurance status. Full models were adjusted for the preceding variables as well as the presence of comorbidities and components of the health care–associated pneumonia definition. LOS indicates length of stay; OR, odds ratio.
