CAM Nu-DESC in Greek

Details and patient eligibility

About

This study attempts to validate the Greek version of the CAM Diagnostic Algorithm and Nu-DESC in patients undergoing surgery under general anesthesia.

Full description

Accurate diagnosis for Greek speaking patients suffering from postoperative delirium is limited by the need for a translation of standardized tools that were investigated for their inter-rater reliability/agreement.

Our primary aim is to validate the Greek version of the CAM Diagnostic Algorithm and Nu-DESC in patients undergoing surgery under general anesthesia. Our secondary aim is to estimate the diagnostic accuracy of NuDESK in our population.

This study will provide the first official Greek translation of CAM and Nu-DESC, according to the ISPOR guidelines, and the first evaluation of their inter-rater agreement.
