BACKGROUND: Aggregate bacterial pneumonia plays a fundamental role in mortality of patients hospitalized with COVID-19.
OBJECTIVE: To estimate the association of aggregated bacterial pneumonia with mortality in patients at Hospital Especialidades "La Raza".
MATERIAL AND METHODS: Analytical cross-sectional study, 252 COVID-19 patients, chest x-ray and culture of bronchial secretion or expectoration. Data taken from the SIOC electronic file and the IZASAlab platform.
RESULTS: 252 participants, positive culture, 89 patients, 35.3%, isolation of K. pneumoniae (22.5%), A. baumannii (20.2%), P. aeruginosa (13.5%) and S. aureus (11.2%), antimicrobial resistance 37.1%. 43.7% died, lung damage greater than 50% RMa 2.25 (95% CI 1.01-5.11) p=0.04 against minor lung damage; microorganism in culture RMa 9.04 (95% CI 3.06-26.74) p=0.000; antimicrobial resistance RMa 7.57 (95% CI 1.34-42.79) p=0.02; S. aureus RMa 1.24 (95% CI 0.36-4.23) p=0.73; A. baumannii RMa 3.74 (95% CI 1.41-9.91) p=0.008; K. pneumoniae RMa 4.12 (95% CI 1.55-10.97) p=0.005; and P. aeruginosa RMa 6.89 (95% CI 1.62-17.61) p=0.01. Uncontrolled Diabetes RMa 1.61 (IC95% 1.1-2.9) p=0.018.
CONCLUSIONS: The development of added bacterial pneumonia increases the probability of death 2 times more, it amounts to 6 times more if there is antimicrobial resistance, it is observed to a greater extent for A. baumannii, K. pneumoniae and P. aeruginosa.
