Risk Factors of Swenson et al for In-Hospital Death of a Patient with an Intra-Abdominal Infection

Description

Swenson et al identified risk factors for hospital mortality for a patient with intra-abdominal infection. These can help to identify a patient who may benefit from more aggressive management. The authors are from the University of Virginia at Charlottesville.

Parameters identified by logistic regression analysis:

(1) age of the patient in years

(2) APACHE II score

(3) location in the hospital

(4) maximum body temperature in °C

(5) cardiac disease

(6) malignant disease

(7) liver disease

(8) renal disease and dialysis dependent

(9) organism AND transplant status

Parameter	Finding	Points
age of the patient	< 70 years	0
	>= 70 years	1
APACHE II score	< 20	0
	>= 20	1
location in the hospital	ICU	1
	non-ICU	0
maximum body temperature	< 38.5°C	1
	>= 38.5°C	0
cardiac disease	absent	0
	present	1
malignant disease	absent	0
	present	1
liver disease	absent	0
	present	1
renal disease	dialysis dependent	1
	none or not dialysis dependent	0
organism and transplant status	resistant organism AND solid organ transplant	1
	susceptible organism OR not solid organ transplant	0

where:

• The Odds Ratios (OR) range from 2.1 to 5.2.

number of risk factors =

= SUM(points for all 9 parameters)

Interpretation:

• minimum number of risk factors: 0

• maximum number of risk factors: 9

• The risk of in-hospital death increases with the number of risk factors.
