Abstract

Introduction: Intravascular catheters are indispensable in modern-day medical practice, particularly in intensive care units (ICUs). The incidence of CRBSI varies considerably by type of catheter, frequency of catheter manipulation, and patient related factors (e.g., underlying disease and acuity of illness). Materials and Methods: It was case-control study conducted in the Department of Microbiology, Darbhanga Medical College, Laheriasri, Bihar, India from January 2020 to December 2020. The number of participants in this study was 100 cases and 100 controls. Patients aged >18 yrs, admitted in intensive care units with intravascular catheters, were included. Skin was cleaned with 70% alcohol prior to catheter removal. Drying was avoided by sealing the tube and transporting the same to the laboratory as soon as possible. In blood processing, blood was collected within 48 hours of catheter collection under all aseptic precautions in a BacT bottle and analyzed using the BacT ALERT system. Antibiotic sensitivity pattern was done by Kirby-Bauer disk diffusion method as recommended by Clinical Laboratory Standard Institute (CLSI). Statistical analyses were done using SPSS 16.0 and strength of association is expressed as odds ratio which was derived using logistic regression analysis. Results: Out of 100 samples, 81% of the isolates were bacteria, while 17% of the pathogens were Candida species and only 2% were polymicrobial. While majority (70.4%, 19/27) of the organism of CRBSI was Gram positive, majority (61.6%, 45/73) of the organism of CRLI were Gram negative.The commonest pathogen of CRBSI was Staphylococcus aureus (12/27) and the least common was Acinetobacter baumannii (1/27). Candida spp. Conclusions: The increasing rate of CRBSI is a matter of concern to our hospital set up. This work will help both the clinicians as well as microbiologists in better management of patients as well as in prevention of nosocomial bloodstream infection, especially due to multidrug resistant organisms.
