Medical resource utilization among patients with ventilator-associated pneumonia: pooled analysis of randomized studies of doripenem versus comparators

Table 4 Microbiologic outcome and resource utilization in patients with ventilator-associated pneumonia due to Pseudomonas aeruginosa

Outcome	Doripenem	Comparator	P value
Eradication rate, n/N (%)^a	16/24 (66.7)	10/24 (41.7)	0.147^b
Median duration, days (95% CI)	(n = 36)	(n = 37)
Mechanical ventilation	7 (5-9)	13 (8-16)	0.031^c
ICU	13 (9-19)	21 (14-30)	0.027^c
Hospital	24 (20-32)	35 (28-N/A)	0.129^c

^a Eradication rate defined as microbiologic eradication or presumed eradication. Twenty-five patients excluded from evaluation of eradication rates for doripenem (n = 12) and comparator (n = 13) because of lack of data.
^b Two-sided Fisher's exact test.
^c Generalized Wilcoxon test.
CI, confidence interval; N/A, not available.
