Abstract:
OBJECTIVETo identify risk factors for Klebsiella pneumoniae carbapenemase-producing Klebsiella pneumoniae (KPC-Kp) colonization in neonates hospitalized in the neonatal intensive care unit (NICU).
METHODSA case-control study was conducted. The case group included nine patients colonized with KPC-Kp between 1 August 2012 and 31 April 2013 and the controls were selected randomly from patients without KPC-Kp colonization during the same period. Univariable analysis and multivariable logistic regression analysis were conducted to identify risk factors for KPC-Kp colonization.
RESULTSThe univariable analysis showed 11 factors associated with KPC-Kp colonization: gestational age, birth weight, length of hospital stay, duration of mechanical ventilation, congenital heart disease, peripherally inserted central catheter, surgical operation, duration of intravenous nutrition, carbapenems use, duration of carbapenems use and glycopeptides use. The multivariable logistic regression analysis showed that exposure to more than 4 days of carbapenems use (OR=18.7, 95%CI: 1.98-175.5, P=0.01) was an independent risk factor for KPC-Kp colonization. The intervention to control KPC-Kp colonization included contact isolation, active surveillance, and rational use of antibiotics.
CONCLUSIONSExposure to prolonged use of carbapenems is an independent risk factor for the development of KPC-Kp colonization in neonates hospitalized in the NICU.
