Popis: Abstract Background Disorientation is an early indicator of developing postoperative delirium (POD), which is associated with increased mortality and cognitive decline. The well-established “Confusion-Assessment-Method-for-Intensive-Care-Unit” (CAM-ICU) for diagnosing POD in intubated patients cannot make use of the feature ‘disorientation’, as this requires verbal communication. Other tools such as the 4AT test for disorientation but are not established in ICU settings. We therefore combined test-variables of the CAM-ICU (level of consciousness, fluctuating mental status and inattention) with verbal testing for disorientation to develop and enhance diagnostic accuracy of the “Confusion Assessment Method for Intermediate Care Unit” (CAM-IMC). In the present study we describe the development and the evaluation of the diagnostic accuracy of the CAM-IMC. Methods We conducted a prospective cohort-study to develop and evaluate the diagnostic accuracy of the CAM-IMC and disorientation for diagnosing POD in non-intubated patients undergoing elective cardiac surgery. All patients were eligible during data collection period. Exclusion criteria were preexisting brain-organic disease, age
