Revised Swiss Emergency Triage Scale (SETS)

The revised Swiss Emergency Triage Scale (SETS) provides better standardization which improves triage of an adult in the Emergency Department.

SETS Level	Significance	Triage
1	life-threatening	immediate
2	potentially life-threatening	within 20 minutes
3	urgent but not life-threatening	within 120 minutes
4	nonurgent	to follow

Parameter:

(1) Glasgow coma scale (GCS)

(2) heart rate in beats per minute

(3) systolic and diastolic blood pressures in mm Hg

(4) shock index (heart rate divided by systolic blood pressure)

(5) respiratory rate in breaths per minute

(6) cyanosis

(7) oxygen saturation in percent

(8) "peak flow" as percent of predicted (will use PEFR)

(9) temperature in °C

(10) blood glucose in mmol/L

Parameter	Finding	SETS Level
Glasgow Coma Scale	<= 8	1
	9 to 13	2
	14 or 15	3 or 4
heart rate	< 40	1
	40 to 50	2
	51 to 129	3 or 4
	130 to 150	2
	> 150	1
blood pressure	systolic >= 230 OR systolic <= 70 OR diastolic >= 130	1
	systolic 181-229 OR systolic 71 to 90 OR diastolic 115-120	2
	systolic 91-180 AND diastolic < 115	3 or 4
shock index	> 1	2
	<= 1	3 or 4
respiratory rate	<= 8	1
	9 to 12	2
	13 to 24	3 or 4
	25 to 35	2
	> 35	1
cyanosis	present	2
	absent	3 or 4
oxygen saturation	< 90	1
	90 to 93	2
	> 93	3 or 4
peak flow	<= 50% of predicted	2
	> 50% of predicted	3 or 4
temperature	< 32°C	1
	32 to 35°C	2
	35.1 to 40°C	3 or 4
	> 40°C	2
blood glucose	< 4 mmol/L	2
	4 to 24.9 mmol/L	3 or 4
	>= 25 mmol/L	2

Performance:

• The system shows high reliability and a low rate of mistriage.
