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

Table 2 Scoring systems and laboratory findings at the time of hospital-acquired pneumonia diagnosis

Clinical and laboratory findings (n = 76)	Pneumonia without subsequent septic shock (n = 47)^a	Pneumonia with subsequent septic shock (n = 29)^a	p value
Time from admission to onset of pneumonia (h)	33.0 (4.0–87.0)	42.0 (22.0–78.0)	0.37
CRP (U/l)	60.0 (33–101)	80.0 (71.0–135.0)	0.13
Leukocytes (G/l)	12.7 (10.1–15.0)	12.6 (4.4–13.3)	0.18
Platelets (G/l)	175.0 (135.0–325.0)	193.0 (79.0–435.0)	0.51
Lactate (mmol/l)	1.3 (1.1–1.7)	1.5 (1.2–2.4)	0.05
PaO₂ ratio/F_IO₂	350 (300–375)	350 (310–385)	0.24

^aData are expressed as median (25/75 percentile). CRP, C-reactive protein; F_IO₂, inspired oxygen concentration; G/l, cells × 10⁹ per liter; PaO₂, arterial oxygen pressure.
