Клиническая микробиология и антимикробная химиотерапия (Sep 2021)
Antimicrobial resistance and antimicrobial therapy modification during COVID19 pandemic in large tertiary hospital
Abstract
Objective. assessment of the evolution of the microbiological landscape of the hospital for the period of operation in 2020 into a pandemic of a new coronavirus infection in various departments, including intensive care units; change depending on the results of antibacterial therapy regimens. Materials and Methods. In a retrospective study, conducted from June to December 2020, in a multidisciplinary hospital working with COVID-19 infection, the resistance of isolated strains of microorganisms was analyzed in patients of different age groups. Resistance was assessed with test points in June and November 2020; depending on this, proposals were made to correct the internal (local) protocols of antimicrobial therapy. Results. The need for frequent and regular microbiological monitoring was confirmed. Further, we understood that the territories of the main and temporary hospital of the City Clinical Hospital No. 40 are heterogeneous and there are obvious differences both in structure and in the level of sensitivity. “In practice, these are two different hospitals”. Within the territories, the branches also differ from each other. When analyzing resistance in ICUs, it was revealed that within each hospital in each department, albeit similar in structure and profile of patients, there is a different level of resistance of strains. Conclusions. The structure of sensitivity generally corresponds to the world data, but for some pathogens it differs significantly. Microbiological monitoring should be carried out not only inside the hospital, but also inside the department. The increase in consumption of carbapenems and protected cephalosporins requires a reassessment of the practice of using AMP in any covid hospital, due to the impact on the epidemic situation both in the ICUs and in the hospital.
