Risk Factors for the First Episode of Klebsiella pneumoniae Resistant to Carbapenems Infection in Critically Ill Patients: A Prospective Study

Table 4

Duration of ICU stay, death, mechanical ventilation, and sedation in patients with KPRC, non-MDR infection, and no infection.

	KPRC; (𝑁=25)	𝑃^∗	Non-MDR bacterial infection; (𝑁=18)	𝑃^#	No bacteria group; (𝑁=39)	𝑃^#
ICU duration (days)	24 (15, 32)	<0.001	20 (9, 32)	0.433	9 (6, 13)	<0.001
Death	15 (60)	0.022	8 (44.4)	0.365	10 (25.6)	0.009
MV duration (days)	20 (9, 31)	<0.001	18 (9, 25)	0.435	7 (4, 11)	<0.001
Duration of sedation (days)	8 (2, 18)	0.003	9 (5, 15)	0.967	4 (2, 8)	0.003

Data are presented as median (25% and 75% quartiles) or 𝑛 (%); KPRC: Klebsiella pneumonia resistant to carbapenems; MDR: multidrug resistant bacteria; MV: mechanical ventilation; ICU: Intensive Care Unit; 𝑃^∗: comparison between three groups; 𝑃^#: KPRC versus non-MDR group, KPRC versus no bacteria group. Results are by univariate analysis.
