Objective
: To determine the mortality and risk factors of mortality in a surgical intensive
care unit (SICU), King Chulalongkorn Memorial Hospital.
Design
: Review of retrospective data.
Setting
: a SICU of a tertiary-care academic medical center.
Patients
: Out of a total of 546 patients admitted to SICU during a one year period (January
I, 2000 -December 31, 2000), 458 (83.9%) had complete medical data which were analyzed.
Measurements and Main Results
: One hundred and ninety-three variables of 6 categories
of patients' characteristics, chronic disease, acute illness, physiologic variables, therapy and miscella-
neous were studied. Univariate and multivariate analyses were used. The SICU and hospital morta-
lity was 8.1 and 14.6 per cent, respectively. Multivariate logistic regression analysis identified seven
variables as independent risk factors for mortality (p
<
0.05): chronic renal failure (adjusted odds ratio
IAOR], 7.5; 95% CI, 3.0 to 19.0; p
=
0.000), coma (AOR, 11.7; 95% CI, 2.4 to 57.4; p
=
0.002),
Staphylococcus aureus
infection (AOR, 15.4; 95% CI, 1.6 to 147.6; p
=
0.018), diagnosis of systemic
inflammatory response (AOR, 2.9; 95% CI, 1.2 to 7.1; p
=
0.017), mechanical ventilation (AOR, 11.2;
95% CI. 2.0 to 61.4; p
=
0.005), having received adrenaline (AOR, 7.1; 95% CI, 2.3 to 22.2; p
=
0.001) and diuretic (AOR, 3.3; 95% CI, 1.4 to 8.1; p
=
0.008). Besides weight (AOR, 0.9; 95% CI,
0.9 to 1.0; p
=
0.002) and having received H
2
-blocker (AOR, 0.2; 95% CI, 0.1 to 0.5; p
=
0.001) were
two independent protective factors for mortality.
Conclusion
: Knowing the risk factors of SICU mortality wiiJ help physicians to improve
patient care, educate patients and their families, optimize ICU resource planning and may decrease
health care costs.
