Patients admitted in Intensive Care Units are at great risk for acquiring nosocomial infections; also there is frequent use of
invasive devices. We conducted a study to isolate and identify the organisms causing infections in ICU and their
antimicrobial resistance pattern. Clinically diagnosed cases of infection after 48 hours of admission in the Medical ICU were included in study.
Depending on type of infections various samples were collected and processed as per standard guidelines. VAP was most common infection
followed by CAUTI and CLABSI. Their rate (per 1000 device days) being 32.04, 7.62 and 12.25. Among the 185 isolates, Gram negative
organisms predominated. A.baumannii was the most frequent isolate followed by K.pneumoniae, P.aeruginosa, S.aureus, E.coli, C.tropicalis,
C.albicans etc. Majority of organisms were highly resistant to common antibiotics used. Problem of multidrug-resistance can be prevented by
rational use of antibiotics after standardised antibiotic susceptibility testing.
