Abstract
The ICDSC demonstrated 97% sensitivity compared to 38% sensitivity for the CAM-ICU in detecting post-cardiac surgery delirium.
- The study involved 110 daily assessments across 31 patients in a specialized cardio-surgical ICU.
- CAM-ICU exhibited 100% specificity, indicating it correctly identified all patients without delirium.
- All false-negative cases in the CAM-ICU were linked to high scores in auditory attention screening.
- The ICDSC's sensitivity varied slightly between the two nurses, at 97% and 94%, respectively.
- Both tools' results were compared against diagnoses made by psychiatrists using established diagnostic criteria.
