ABSTRACT
INTRODUCTION:
Infectious disease management in intensive care units (ICUs) is becoming more difficult due to increasing antimicrobial resistance. Hence, the aim of this study was to explore the nature of pathogens mostly encountered in an ICU and determine their antibiotic susceptibility through the compilation of ICU-specific antibiogram.METHODOLOGY:
A descriptive cross-sectional study of the culture and sensitivity reports of ICU patients was conducted in a tertiary care hospital. An antibiogram was created according to the Clinical Laboratory Standards Institute (CLSI) M39-A4 guidelines.RESULTS:
Of the total 597 reports, the most common specimen type were respiratory secretions (n = 174), followed by blood (n = 128), wounds (n = 108), and urine (n = 80). Out of 597 isolates, the most frequently isolated bacteria were Klebsiella species (n = 156), Pseudomonas aeruginosa (n = 117), Escherichia coli (n = 112), Enterobacter species (n = 56), Acinetobacter species (n = 52), Proteus species (n = 39), Staphylococcus aureus (n = 34) and coliform species (n = 31). An 84% multidrug resistance (MDR) rate was reported among the isolates studied, with Acinetobacter species being at the top with a 98% MDR rate.CONCLUSIONS:
A substantial and alarming MDR rate was observed in our study. Furthermore, our findings demonstrated a potential interest in developing an ICU-specific antibiogram that is informative to clinicians in their clinical decision-making related to antibiotic therapy.Palavras-chave
