Uni- and multivariable logistic regression analysis of factors associated with 30- and 180-day mortality for patients admitted from home. Multivariable analysis was adjusted for age, sex, Scottish Index of Multiple Deprivation, American Society of Anesthesiologists grade, and COVID-19 within 30 days.
