Abstract

Background: Blood stream infections (BSIs) occur more frequently in patients hospitalized in Intensive care units (ICUs). Intravascular devices are the most frequent predisposing factor causing BSI.
Objective: To compare the proportion, risk factors, microbiological profile of Blood stream Infections and Central line associated bloodstream infection in Cardiology Intensive care units (CICU) and Cardiothoracic Intensive care units (CTICU).
Methodology: This is a prospective study conducted by the Dept. of Microbiology along with Cardiology Intensive care unit(CICU), and Cardiothoracic Intensive care unit (CTICU) of a tertiary care centre, from June 1st 2017-Oct 312018.Laboratory confirmed BSIs (LCBSI’s), occurring more than 48hrs after ICU admission were included in the study. Identification of pathogens were done by standard methods.
Results: A total of 1640 blood cultures were analyzed (CICU=890,CTICU=750).73 Primary BSIs were observed with male preponderance.68/73 diagnosed to have non CLABSI (CTICU=35/68 51.4%, CICU=33/68, 48.5%) and 5/73 cases diagnosed to have CLABSI (CTICU=5/73, 6.84% CICU=0%) 47.94% of our isolates were Gram negative pathogens with as the predominant followed by 35.6% of Gram positive with as the major pathogen & 16.4% were Candida spp. 20.5% were multi drug resistant and 10% were ESBL producers. Prevalence and incidence rates were high in CTICU (5.3% & 1.5%) compared to CICU (3.7% & 0%) of BSI & CLABSI respectively.
Conclusion: BSI is preventable costly complication that occur with greater frequency in the ICU settings. Strict adherence to Infection control measures such as hand hygiene, aseptic precautions during blood culture collection and bundle care measures can decrease the BSI and CLABSI incidence rates.
