The Ultra-Brief CAM (UB-CAM) is a two-step protocol that combines UB-2 items (Fick et. al., 2015;2018) and 3D-CAM (Marcantonio, et. al., 2014) items to identify the presence of delirium. Delirium is an acute, reversible confusion that is preventable and treatable. Delirium occurs in more than 25% of hospitalized older adults. Early recognition, evaluation and treatment is key to preventing complications and improving outcomes. This App is designed to be an initial screen for delirium and is not a medical diagnosis. Please see a doctor’s advice before making any medical or health care decisions.
