Bacterial resistance in the intensive care unit of developing countries: Report from a tertiary hospital in Kazakhstan.

OBJECTIVES

The aim of this study was to describe the patterns of antimicrobial resistance (AMR) of bacterial isolates causing hospital-acquired infections (HAIs) in the intensive care unit (ICU) of a tertiary hospital in Kazakhstan.

METHODS

This was a retrospective analysis of AMR in the ICU of the National Research Center for Oncology and Transplantation (Astana, Kazakhstan) during the year 2015.

RESULTS

During the study period, 546 patients were admitted to the ICU, of whom 135 (24.7%) developed at least one HAI. Most HAIs caused by Gram-positive bacteria were due to Enterococcus faecalis, which were resistant to aminoglycosides in >70% cases. Gram-negative bacteria were isolated in ca. 50% of cases, thus representing the greatest burden of HAIs. Very high resistance rates to ceftriaxone, cefotaxime and cefuroxime were observed. Moreover, Pseudomonas aeruginosa and Acinetobacter baumannii were resistant to carbapenems in <20% and in ca. 45% of cases, respectively.

CONCLUSION

This study demonstrates the urgent need to implement more rational use of antimicrobials in Kazakhstan, which can be done only by establishing a proactive surveillance system along with an appropriate infection control programme.
