Abstract:
Introduction:
Central Venous Catheters considered source of Central line-associated bloodstream infections (CLABSI). Malignancy carries Odds-Ratio of 1.35 for HAIs. As per western literature, Gram positive cocci (GPC) infections are frequently associated with these IV devices. In Indian cancer settings, Gram negative bacteria (GNBs) were found to be more common cause of infections.
Methods:
Prospective CLABSI surveillance study (CDC/NHSN) from tertiary-care cancer-centre, Dr. BRAIRCH, AIIMS-New Delhi, India. CLABSI etiology data from 2020 to 2023 was included for this study.
Results:
We calculated data for 16,540, 29062, 35624, 37426 patient-days in year 2020, 2021, 2022, 2023 and 3658, 5687, 6758, 7478 central-line days in year 2020, 2021, 2022, 2023, respectively. In year 2020, 54% CLABSI etiology was due to GNBs with predominant being Klebsiella pneumoniae (25.4%), while among GPCs, 38% were due to Staphylococcus spp. In year 2021, 58% CLABSI etiology was due to GNBs with predominant being Klebsiella pneumoniae (35%), while among GPCs, 34% were due to Staphylococcus spp. In year 2022, 45% CLABSI etiology was due to GNBs with predominant being Escherichia coli (19%), while among GPCs, 9% were due to Enterococcus spp. In year 2023, 80% CLABSI etiology was due to GNBs with increase of Acinetobacter spp. (19%) while among GPCs, 10% were due to Enterococcus spp.
Conclusion:
Etiology of central line blood stream infections throughout the world is evolving around highly drug resistant Klebsiella spp, Acinetobacter spp, Staphylococcus spp & Enterococcus spp. This is a cause of concern and requires strict infection control practices for control of these infections.
