Late onset sepsis (LOS) and central-line associated blood stream infection (CLA-BSI) contribute toward the mortality and morbidity in prematurely born infants. The aim of this study is to investigate the effects of hospital-wide and unit-based interventions on LOS and CLA-BSI in infants born at <32 weeks gestation.
Intensive care, high dependency days and catheter days were obtained from the unit database and blood culture results from a microbiology laboratory database. Poisson regression was used to evaluate the effects of interventions on LOS and CLA-BSI.
Quarterly rates of LOS reduced from 26.1 to 2.9 per 1000 intensive care, high dependency days and CLA-BSI from 31.6 to 4.3 per 1000 catheter days between 2007 and 2012. Appointment of a hospital specialist vascular device nurse, a change in the mode of administration of vancomycin, standardization of the hospital skin and hub disinfection policy and the introduction of a venous infusion phlebitis scoring system were associated with a reduction of LOS to 55% (95% confidence interval: 40–74%) and CLA-BSI 45% (95% confidence interval: 33–61%) of pre-intervention levels. The standardization of the neonatal unit policy for skin disinfection and a move to a new building were associated with reductions of LOS to 64% (47–87%) and 54% (34–88%), respectively, and aseptic no touch technique for infusion access with CLA-BSI to 53% (37–75%) of pre-intervention levels.
A multifaceted approach involving changes in antimicrobial and skin disinfection policy, training for aseptic no touch technique and surveillance resulted in sustained reduction in LOS and CLA-BSI rates.
