Suggestions for imaging type and location per triage code

Triage code	Medical attention	Imaging	Location
T1—red	Immediate	WBCT or angio-intervention, if needed	Radiology ED, angiosuite
T2—yellow	Urgent, able to wait	WBCT or ultrasound, radiography, selected CTa	Radiology ED
T3—green	Walking wounded	Selective imaging	Radiology department
T4—black	Unlikely to survive	No imaging

Radiology ED, radiology facilities located in or next to the emergency department; WBCT, whole-body computer tomography.

^aImaging strategy dependent on local facilities and capacity.

Highest rate of triage errors occur in T1 and T2 groups, the role for imaging is biggest in these groups.
