Abstract

Aims and objectives: Central line-associated bloodstream infection (CLABSI) is among one of the preventable healthcare-associated infections (HAIs). The data for the CLABSI rate in liver care intensive care unit (LCICU) patients are scarce, so the present study was conducted to ascertain the CLABSI rate, the microbiological profile, and the impact of preventive measures for reduction of infection. Materials and methods: This is a prospective observational study done on LCICU patients during the period of January 2017–December 2018. We followed up patients on the central venous catheter for the development of CLABSI as a part of routine surveillance of HAIs. The impact of introduction and implementation of the CLABSI bundle to reduce the CLABSI rate was analyzed and the microbiological profile of infection was determined. Results: During the study period, the total number of patients admitted in LCICU were 1,336 (648 in 2017 and 688 in 2018) and a total of 995 central lines were inserted for various indications. A total of 57 patients were meeting the CLABSI criteria among 7,324 central line catheter days of surveillance. In year 2017, rate of CLABSI was 11.78/1,000 catheter days and after implementation of the bundle in 2018 the rate reduced to 3.99/1,000 catheter days. Gram-negative organisms (86%) predominated with Pseudomonas aeruginosa being the most common pathogen (19.3%). Out of 49 isolates of gram-negative bacilli (GNB), 40 (81.6%) were multidrug resistant (MDR) and 9 (18.4%) were pan-drug resistant. Conclusion: We found significant reduction in the CLABSI rate after implementation of the bundle of care. Gram-negative bacilli were the most common pathogen in our study and antimicrobial resistance was very high, which suggest hospital environment as a source of infection. Clinical significance: Knowledge of the microbiological profile and the preventive strategy of CLABSI is essential for prevention and timely initiation of the most appropriate anti-infective therapy, if it happens.
