Abstract
Background: Intensive care units (ICUs) in developing countries constitute a high risk for patients acquiring infection by multidrug-resistant organisms (MDROs). The rise in antimicrobial resistance (AMR) threatens the effective prevention and treatment of an increasing range of infections. The present study analyzed the local trends of AMR in Gram-negative isolates of ICU patients from a tertiary care facility in North India.
Methods: This retrospective study was conducted over 5 years (January 2018-December 2022). All bacterial isolates from patients admitted to ICU during the study period were included in the study, and their AMR pattern was analyzed. In addition, sensitivity trends of different antimicrobials against the common Gram-negative bacteria were analyzed, and AMR trends were analyzed over the study period.
Results: Klebsiella spp. was the most common isolate in samples received from ICU. A rise of carbapenem-resistant microorganisms was observed over the study period. Escherichiacoli and Klebsiella spp. showed around 10% and a 17% decrease in susceptibility to carbapenems, respectively. In contrast, a marked 29% decrease in sensitivity to carbapenems was observed in Acinetobacter spp.
Conclusion: The inception of integrated stewardship measures has shown a rising trend in susceptibility and is the need of the hour to prevent the spread of MDROs. Surveillance studies help us understand the impact of AMR in hospitals and help plan prevention programs.
