Pre- and post-COVID-19 evaluation of antimicrobial susceptibility for healthcare-associated infections in the intensive care unit of a tertiary hospital

Abstract

INTRODUCTION:

Antimicrobial resistance has worsened since the onset of COVID-19.

METHODS:

This study involved patients admitted to the adult intensive care unit (ICU) of a tertiary hospital. Pre- and post-COVID-19 data were analyzed. The healthcare-related infections (HCRIs) reported between January 2018 and January 2020 and during the pandemic between February and July 2020 were compared.

RESULTS:

Antimicrobial resistance increased during the pandemic, especially for Klebsiella pneumoniae isolates, with a rate increase from 5% to 50% for Polymyxin B.

CONCLUSIONS:

The susceptibilities of the main pathogens associated with HCRIs in the ICU changed and should be considered in managing severe COVID-19.
