2CONFUSION ASSESSMENT METHOD (CAM)
The CAM is a validated tool to be used in assisting with the differential diagnosis of Delirium. It
should be used for any older person who appears to be disorientated / confused or who has any
change in behaviour or LOC. It is important that the CAM is used in conjunction with a formal
cognitive assessment (eg AMT/ SMMSE), good clinical and medical assessment, together with
baseline cognition information from carers/family or the community or residential aged care service
