Risk factors for healthcare-associated infection in a neonatal intensive care unit / 中国感染控制杂志

ABSTRACT

Objective To understand the occurrence and risk factors of healthcare-associated infection(HAI) in a neonatal intensive care unit(NICU).Methods Neonates who were admitted to the NICU of a hospital from January 2012 to December 2014 were investigated retrospectively,risk factors for HAI were performed univariate analysis.Results A total of 760 neonates were included in the investigation,198 neonates developed 259 times of HAI,incidence of HAI was 26.05％,case incidence of HAI was 34.08％,incidence of HAI per 1 000 patient days was 9.50‰;the main infection site was lower respiratory tract (n =92,35.52％);among 259 cases of HAI,172 strains of pathogenic bacteria were isolated,the major pathogen was Acinetobacter spp.(n =40,23.26％);incidence of HAI was high in neonates with gestational age ≤32 weeks,birth weight≤1 500 g,length of hospital stay ≥10 days,duration of antimicrobial use≥10 days,mechanical ventilation,deep venous catheterization,and feeding intolerance,difference was statistically significant (all P＜0.001).Conclusion Incidence of HAI in NICU is high,effective prevention and control measures should be formulated according to its risk factors,so as to reduce the occurrence of HAI in neonates.
