Eight year study on evolution of antimicrobial resistance in an antimicrobial-naïve trauma population

From 1st January 2012-31st December 2019, 4305 isolates were obtained from 1969 patients. Most frequent occurring organism were gram negatives among which A. baumannii was common followed by K. pneumoniae, and P. aeruginosa. Retrospective analysis showed 7 outbreaks/clusters during the study period and all the outbreaks occurred from October to December in each year. The increasing trend of AMR pattern emphasizes to strengthen infection control practices and sustained AMR surveillance.
