Effect of a surveillance system for decreasing neonatal nosocomial infections.

subject

description

Nosocomial infection in very low birthweight (VLBW) infants is a common complication with high morbimortality. New strategies to reduce its occurrence have recently led to the development of neonatal surveillance programs.To determine whether the NeoKissEs surveillance system implementation in our neonatal unit has been associated with a decrease in nosocomial infection in VLBW infants, as well as a reduction in the use of antibiotics and central venous catheters (CVC).Retrospective and descriptive study of infants1500 g admitted between January 2011 and December 2017. Rates of use of antibiotics and CVC were calculated, as well as late-onset sepsis incidence. Data were compared before and after the surveillance system implementation.299 patients were recruited. We excluded seven patients, who died72 h. Of the remainder (n = 292), 149 were in the pre-intervention period and 143 in the post-intervention period. We found a significant decrease in the incidence density of sepsis comparing these two periods (5.98 vs. 4.08) (p = 0.03). Although no differences in antibiotic and CVC rates of use between both groups were found, a significant decrease in antibiotic use was observed comparing the first and last year of the intervention (38% vs. 24%) (p = 0.03). A higher percentage of breastfed infants was observed (39% vs. 59%) (p = 0.001) in the post-intervention group.Surveillance systems are useful to reduce nosocomial infection in VLBW infants. Reduction in antibiotic and CVC use requires longer intervention time. Promotion of breastfeeding seems to be a very effective associated strategy.
