Objective:To validate The Proxy Test for Delirium (PTD) as a screening tool used by nurses to detect delirium in patients admitted to the Intensive Care Unit (ICU).

Methods:A convenient sample of 288 patients who were eighteen years and above admitted to ICU at King Khalid University Hospital (KKUH) were observed in a cross sectional study. The screening tools were used blindly to detect delirium. These tools were; The PTD perform by the patient's primary nurse at the end of their shift, The CAM performed by a trained research assistant, and a clinical neuropsychiatric evaluation based on DSM-5 criteria performed by Psychosomatic Medicine specialist. The data were analyzed using the SPSS and Medcalc programs.

Results:The result suggests that using a cutoff score more than 5, the PTD has a sensitivity of 60.00%, specificity of 94.29%, positive predictive value of 0.818 and negative predictive value of 0.846. The sensitivity of CAM was 53.33% and the specificity was 100.00%. The positive predictive value and the negative predictive value were 1 and 0.833, respectively. Conclusion: The PTD has shown to be more sensitive in detecting delirium cases than CAM in the ICU. In the other hand, CAM has shown to be more specific.
