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

Table 5 Intensive care unit outcome

Outcome (n = 76)	Pneumonia without subsequent septic shock (n = 47)^a	Pneumonia with subsequent septic shock (n = 29)^a	p value
MOF (worst score during ICU stay)	4 (3–5)	8 (6–9)	≤ 0.01
ICU stay (days)	12 (8–18)	19 (9–30)	0.06
Survivor/non-survivor^b	67/0	16/13	≤ 0.01

^aData are expressed as median (25/75 percentile). ^bSurvivor/non-survivor analyzed by X²-test. ICU, intensive care unit; MOF, Multiple Organ Failure score.
