Resistance is reality: findings from the first Ukrainian cumulative antibiogram.

Background: Antimicrobial resistance is a global health threat resulting in significant morbidity and mortality worldwide. Until recently, in Ukraine, cumulative antibiograms (CuAbgms) have never been available.

Objectives: To describe the first CuAbgm developed in Ukraine.

Methods: We developed a CuAbgm for the Okhmatdyt National Specialized Children's Hospital using data from WHONET. Antimicrobial susceptibility testing was performed per EUCAST guidelines. The CuAbgm was developed using guidance from CLSI.

Results: For Escherichia coli, 66% and 69% of isolates were susceptible to ceftazidime and ceftriaxone, respectively, and 99% were susceptible to meropenem. For Klebsiella pneumoniae, 26% and 27% of isolates were susceptible to ceftazidime and ceftriaxone, respectively, and only 59% were susceptible to meropenem. Of the carbapenem-resistant K. pneumoniae isolates that underwent additional susceptibility testing, only 38% were susceptible to ceftazidime/avibactam. For Pseudomonas aeruginosa, only 53% were susceptible to meropenem. Of those that were resistant to meropenem and underwent additional susceptibility testing, only 12% were susceptible to ceftazidime/avibactam. Similarly, for Acinetobacter spp., only 37% of isolates were susceptible to meropenem. Susceptibility to ampicillin/sulbactam was also low at 45%. The oxacillin susceptibility rate for Staphylococcus aureus was 99%.

Conclusions: In this first-ever CuAbgm developed in Ukraine, high levels of resistance were demonstrated among Gram-negative bacteria. CuAbgms should be prioritized in laboratories in Ukraine to guide empirical antimicrobial therapy, infection control and antimicrobial stewardship policies. This is of heightened relevance during wartime, when there is a need for healthcare systems to treat complex and infected penetrating and blast-related injuries.
