Abstract:
Secondary bacterial infections occurred in 13.9% (5 of 36) of critical ill patients with coronavirus disease 2019. All 5 patients had been admitted to intensive care unit and received mechanical ventilation before developing bacterial infection. Active surveillance of culture should be performed for critically ill patients. Prevention of nosocomial infection should to be taken seriously.
Insights
Secondary bacterial infections affected 13.9% of critical coronavirus disease 2019 patients. Intensive care unit admission and mechanical ventilation increased infection risk, highlighting the need for surveillance and prevention.
Area of Science:
- Critical care medicine
- Infectious diseases
- Microbiology
Background:
- Coronavirus disease 2019 (COVID-19) can lead to severe critical illness.
- Critically ill patients are susceptible to secondary bacterial infections.
- Intensive care unit (ICU) environments pose risks for healthcare-associated infections.
Purpose of the Study:
- To determine the incidence of secondary bacterial infections in critical COVID-19 patients.
- To identify risk factors associated with these infections.
- To emphasize the importance of infection control measures.
Main Methods:
- Retrospective analysis of 36 critically ill patients with COVID-19.
- Review of patient data including ICU admission and mechanical ventilation status.
- Culture surveillance for bacterial pathogens.
Main Results:
- A 13.9% incidence of secondary bacterial infections was observed (5 out of 36 patients).
- All infected patients were admitted to the ICU and required mechanical ventilation.
- Bacterial infections developed in patients already receiving intensive care.
Conclusions:
- Secondary bacterial infections are a significant concern in critically ill COVID-19 patients.
- Mechanical ventilation and ICU stay are key risk factors.
- Active culture surveillance and stringent prevention of nosocomial infections are crucial.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
