Surveillance on healthcare-associated infection in a neonatal intensive care unit of a hospital for three consecutive years / 中国感染控制杂志

ABSTRACT

Objective To investigate healthcare-associated infection (HAI)in neonatal intensive care unit(NICU),and provide reference for controlling HAI in newborns.Methods Targeted surveillance on HAI in all newborns in NICU of a hospital from January 2011 to December 2013 was performed by prospective investigation method.Results A total of 5 365 newborns were monitored,128 newborns developed 133 times of HAI,HAI rate and HAI case rate was 2.39% and 2.48% respectively.The major infection sites were conjunctiva (33.08%),upper respiratory tract (23.31%)and skin soft tissue (17.29%).The daily infection rate was 3.32‰(128/38 528),vascular catheter usage rate and respirator usage rate was 1.75%(676/38 528)and 1.09%(420/38 528)respectively.The difference in vascular catheter usage rate and res-pirator usage rate in newborns with different body weight had statistical difference (χ2 =3 075.22;442.46,both P 2 500 g was 16.67%, 12.26%,4.15% and 1.06% respectively.None newborns developed catheter-related bloodstream infection(CRBSI),the incidence of ventilator-associated pneumonia (VAP )was only 4.76‰(2/420).A total of 51 specimens were sent for de-tection,27 pathogens were isolated,the major were gram-positive bacteria(55.56%).Conclusion The incidence of HAI in newborns is high,the main infection sites are eye,upper respiratory tract,and skin and soft tissue.
