- Selected diagnostic-accuracy studyBeyer LP, Gathen LVZ, Rayah BE, Dewald O, Zieschang T, Diers A, et al. Disorientation as a delirium feature in non-intubated patients: development and evaluation of diagnostic accuracy of the 'Confusion Assessment Method for Intermediate Care Unit' (CAM-IMC) - a prospective cohort study. BMC anesthesiology. 2024;24(1):451. doi: 10.1186/s12871-024-02849-3. PMID: 39673057.
This diagnostic-accuracy study evaluated CAM-IMC in postoperative intermediate-care setting for non-intubated patients against experienced reference-rater delirium diagnosis. It reported sensitivity of 96% and specificity of 94% in 155 elective cardiac-surgery patients; 624 paired observations.
