Circulating immune parameters predicting the progression from hospital-acquired pneumonia to septic shock in surgical patients

Table 1 Basic patient characteristics and etiology of pneumonia at the time of admission to the intensive care unit

Characteristics and etiology (n = 76)	Pneumonia without subsequent septic shock (n = 47)^a	Pneumonia with subsequent septic shock (n = 29)^a	p value
Age (years)	49 (36–58)	54 (47–69)	0.18
BSA (m²)	1.9 (1.8–2.0)	1.9 (1.8–2.0)	0.64
APACHE III	39 (31–50)	38 (32–53)	0.58
MOF score	3.0 (1.0–4.0)	4.5 (2.7–6.0)	0.09
Infections Gram+/Gram-	18/21	8/15	= 0.99

^aData are expressed as median (25/75 percentile). APACHE III, Acute Physiology and Chronic Health Evaluation III score at the time of admission to the intensive care unit; BSA, body surface area; Gram+, Gram-positive; Gram-, Gram-negative; MOF, Multiple Organ Failure score.
