Risk Factors of Edna and Bjerkeset for Infection in a Trauma Patient Including the Amount of Blood Transfused

Description

Edna and Bjerkeset identified risk factors associated with infection in trauma patients, including the amount of blood transfused. This can help identify a patient who may require closer monitoring and more aggressive management. The authors are from Innherred Hospital in Levanger, Norway.

Parameters:

(1) Injury Severity Score (ISS)

(2) age of the patient in years

(3) surgery

(4) amount of blood transfused

Parameter	Finding	Odds Ratio
injury severity score (ISS)	< 15	1
	>= 15	7.8
age of the patient	<= 64 years	1
	65 - 79 years	5.3
	>= 80 years	8.4
surgery performed	no	1
	yes	3.1
amount of blood transfused	0	1
	1 to 4 units	1.6
	>= 5 units	6.4

after Table 2, page 660

product of the odds ratios =

= PRODUCT(odds ratios for all 4 parameters)

Interpretation:

• minimum product: 1

• maximum product: 1,300

One way of interpreting this might be:

ROUND (LOG10 (product))	Risk of Infection
0	low
1	moderate
2	high
3	very high
