We verified an independent association between hypoactive and mixed delirium subtypes and hospital mortality in a model adjusted for several possible confounders (age, sex, marital status, referring unit, functional status, cognitive status, nutritional status, comorbidities, polypharmacy, vital signs, glomerular filtration rate, urea, albumin, total leucocytes, C-reactive protein; Table 2). Here, ALB is linked to delirium.
