Background
There is a scarcity of studies evaluating the microbial profile, antimicrobial susceptibility, and prevalence of MDR/XDR pathogens causing medical device-associated infections (MDAIs). The present study was sought in this regard.
Materials and methods
An ambispective-observational, site-specific, surveillance-based study was performed for a period of 2 years in the intensive care unit (ICU) and high dependency unit (HDU) (medicine/surgery) of a Tertiary-care University Hospital. Three commonly encountered MDAIs including central-line-associated bloodstream infections (CLABSI), catheter-associated urinary tract infections (CAUTI), and ventilator-associated pneumonia (VAP), were targeted.
Results and conclusion
Of the total 90 patients, 46 (51.1%) were admitted to the ICU (medicine/surgery), and the remaining 44 (48.8%) were admitted to the HDU (medicine/surgery). The median (P

) age of the total patients was 55 (43.1–62.3) years. Male 61 (67.8%) preponderance was observed. Sixty-two of 90 (68.9%) were immunocompromised. A total of 104 pathogens causing MDAIs were isolated.
Staphylococcus epidermidis (CoNS), and Staphylococcus capitis
were commonly isolated multi-drug resistant (MDR) gram-positive pathogens causing MDAIs. Similarly, carba-resistant
Klebsiella pneumoniae, Stenotrophomonas maltophilia, and
carba-resistant
Acinetobacter baumanni
were commonly isolated MDR gram-negative pathogens causing MDAIs. Five of 9 (55.5%)
K. pneumoniae
and three of 9 (33.3%)
S. maltophilia
isolates were found to be extensively drug resistant. Among
Candida, C. parapsilosis
was the most prevalent fungal pathogen causing CLABSI and CAUTI in patients admitted to ICU/HDU.
