Abbreviated cognitive test for delirium

Abstract

The cognitive test for delirium (CTD) was recently developed to identify delirium in an intensive care unit (ICU) setting. Stepwise discriminant analyses using the original validation sample indicated that a total score formed by summing only two of the nine content scores (visual attention span and recognition memory for pictures) maintained good reliability (coefficient alpha = 0.79) and the ability to discriminate delirium from dementia, schizophrenia, and depression (p < 0.0001) and delirium from moderate to severe dementia (p < 0.0002). This abbreviated version of the CTD is more practical for use by ICU clinicians.
