A Comparison of Three Scores to Screen for Delirium on the Surgical Ward

Abstract

All scores showed high specificity but differed in their sensitivity. The Nu-DESC proved to be the most sensitive test for screening for a postoperative delirium on the surgical ward followed by the CAM and DDS when compared to the gold standard.

Validation of the Confusion Assessment Method in Detecting Postoperative Delirium in Cardiac Surgery Patients

“…24,38 In our study, sensitivity and specificity rates of CAM for detection of delirium overall were 68% and 90%, respectively. Other investigators [38][39][40] have had similar results. Moreover, our results confirm those obtained in a previous study in which Rolfson et al 24 analyzed the validity of the CAM in detecting postoperative delirium in patients undergoing isolated CABG.…”

Delirium rating scales in critically ill patients: a systematic literature review

“…(14) The scale was created by modifying an instrument for the evaluation of alcohol withdrawal syndrome (Clinical Withdrawal Assessment for Alcohol - CIWA-Ar). (23,24) Therefore, it is a useful scale to assess the degree of delirium and guide treatment, and the tool may also serve as a diagnostic scale. The scale exhibited good correlation between examiners, as long as the examiners were previously trained in the scale's application.…”

Managing ICU delirium

“…A good agreement between both scores was found as indicated by the kappa coefficient of 0. 80 Importantly, patients with delirium according to the criteria of the DSM-IV had a significantly longer duration of anesthesia and a significantly increased length of stay in the ICU and also an increased postoperative hospital stay [34].…”
