SPEED (Sepsis Patient Evaluation in the Emergency Department) Score of Bewersdorf et al

Description

Bewersdorf et al reported the Sepsis Patient Evaluation in the Emergency Department (SPEED) Score for risk stratification of septic patients in the Emergency Department (ED). The authors are from University of Malaya and University Medical Center Utrecht.

Patient selection: sepsis in the ED

Outcome: mortality

Parameters:

(1) immune status

(2) blood pressure

(3) body temperature

(4) hypoxemia

(5) hematocrit in percent

(6) serum lactate concentration

(7) pneumonia

(8) acidosis

Parameter	Finding	Points
immune status	normal	0
	immunosuppressed	3
blood pressure	normal or high	0
	hypotension	3
body temperature	normal or high	0
	hypothermia	3
hypoxemia	absent	0
	present	2
hematocrit	normal or high	0
	low (anemic)	2
serum lactate	low	0
	elevated	2
pneumonia	absent	0
	present	2
acidosis	absent	0
	present	1

total score =

= SUM(points for all 8 parameters)

Interpretation:

• minimum score: 0

• maximum score: 18

• The higher the score the greater the risk of mortality.

Total Score	Mortality in Derivation Set	Mortality in Validation Set
0 to 3	11%	7%
4 to 6	30%	25%
7 to 9	57%	50%
10 to 18	92%	72%

Performance:

• The area under the ROC curve is 0.83 in the derivation set and 0.80 in the validation set.
