This study aimed to investigate the impact of a structured, objective, microbiological monitoring program on the prognosis of COVID-19 patients with mechanical ventilation. The results showed that ventilator-associated pneumonia (VAP) was a common complication in COVID-19 patients. In contrast to previous studies, implementing a structured microbiological monitoring program did not increase the mortality rate of COVID-19 patients with bacterial coinfection or VAP. Therefore, standardized, objective microbiological screening can help detect coinfections and ventilator-associated infections, improve anti-infective therapy, and positively influence patient outcomes.
Background: In past influenza pandemics and the current COVID-19 pandemic, bacterial endotracheal superinfections are a well-known risk factor for higher morbidity and mortality. The goal of this study was to investigate the influence of a structured, objective, microbiological monitoring program on the prognosis of COVID-19 patients with mechanical ventilation. Methods: A structured microbiological monitoring program (at intubation, then every 3 days) included collection of endotracheal material. Data analysis focused on the spectrum of bacterial pathogens, mortality, as well as intensive care unit (ICU), hospital, and mechanical ventilation duration. Results: A total of 29% of the patients showed bacterial coinfection at the time of intubation, and within 48 h, 56% developed ventilator-associated pneumonia (VAP). Even though patients with VAP had significantly longer ICU, hospital, and mechanical ventilation durations, there was no significant difference in mortality between patients with VAP pneumonia and patients without bacterial infection. Conclusion: VAP is a common complication in COVID-19 patients. In contrast to already published studies, in our study implementing a structured microbiological monitoring program, COVID-19 patients with bacterial coinfection or VAP did not show higher mortality. Thus, a standardized, objective, microbiological screening can help detect coinfection and ventilator-associated infections, refining anti-infective therapy and positively influencing patient outcomes.
