CLABSI reduction using evidence based interventions and nurse empowerment: a quality improvement initiative from a tertiary care NICU in Pakistan

Abstract

Objective Central line associated bloodstream infection (CLABSI) is an important cause of morbidity and mortality in the neonatal intensive care unit (NICU). We designed a CLABSI Prevention Package (CPP) to decrease NICU CLABSI rates, using evidence-proven interventions. Design This was a quality improvement (QI) project. Data collection was divided into three phases (pre-implementation, implementation and post implementation). SQUIRE2.0 guidelines were used to design, implement and report this QI initiative. Setting A tertiary care level 3 NICU at the Aga Khan University Hospital (AKUH), Karachi, Pakistan. Patients All patients admitted to the AKUH NICU from 1 January 2016 to 31 March 2018 who had a central line in place during their NICU admission. Interventions CPP used evidence-based interventions focusing on hand hygiene, aseptic central line insertion techniques and central line care, prevention of fungal infections and nurse empowerment. Main outcome measures CLABSI rates pre and post intervention were recorded. Secondary outcomes were risk factors for CLABSI, device (central line) utilisation ratio, CLABSI related mortality and micro-organism profile. Results CLABSI rates decreased from 17.1/1000 device days to 5.0/1000 device days (relative risk (RR)=0.36, CI=0.17–0.74). Device (central line) utilisation ratio declined from 0.30 to 0.25. Out of 613 patients enrolled in our study, 139 (22.7%) died. Mortality was higher in CLABSI group (n=20, 44%) as compared with non CLABSI group (n=119, 21.1%) (p<0.001). Gestational age of <27 weeks was an independent risk factor for CLABSI (RR=4.45, CI=1.10–18.25, p=0.03). A total of 158 pathogens were isolated among which 68 were associated with CLABSI. Gram-negative bacteria 31 (47.7%) were the most common cause of CLABSI. Ninety-seven (61%) micro-organisms were multi-drug resistant. Conclusions CPP was effective in decreasing NICU CLABSI rates and can be used as a model to decrease NICU CLABSI rates in low or middle-income countries.
