Confusion Assessment Method (CAM)

Summary

CAM was intended to provide a new standardized method to enable clinicians not trained in psychiatry to identify delirium quickly and accurately in both clinical and research settings. Both a long and short version of the CAM are available. The long version is a comprehensive assessment instrument that screens for clinical features of delirium and correlates to DSM IV criteria. The short version includes only those four features that were found to have the greatest ability to distinguish delirium from other types of cognitive impairment. There is also a CAM-ICU version for use with non-verbal mechanically ventilated patients.

Memorial Delirium Assessment Scale (MDAS)
