Klebsiella pneumoniae as leading cause of pyogenic liver abscess: Three years study in Southern Vietnam

Table 2 Management and inhospital outcomes of liver abscesses by Klebsiella pneumoniae vs non-Klebsiella pneumoniae

Characteristic	Overall (n = 106)	K. pneumoniae (n = 83)	Non-K. pneumoniae (n = 23)	P value1
Management during index admission
Drainage at admission	41 (38.7)	32 (38.6)	9 (39.1)	0.960
Drainage after medical therapy	44 (41.5)	33 (39.8)	11 (47.8)	0.487
Surgery at admission	4 (3.8)	3 (3.6)	1 (4.3)	> 0.999
Surgery after medical therapy	4 (3.8)	4 (4.8)	0 (0)	0.575
Outcomes
LOS (days)	9.0 (6.0-14.0)	10.0 (6.0-15.0)	8.0 (6.0-12.0)	0.324
In-hospital mortality	11 (10.4)	11 (13.3)	0 (0)	0.116

¹P-values were calculated using the Student’s t test or Mann-Whitney U test for continuous variables and the χ² test or Fisher exact test for categorical variables, as appropriate.

LOS: Length of stay; K. pneumoniae: Klebsiella pneumoniae.
