Background: During the COVID-19 pandemic, thousands of patients were hospitalized in Peru. During this period, the incidence of health care-associated infections increased significantly, a high percentage of which were caused by multidrug-resistant (MDR) microorganisms. The acquisition of these infections could have negatively impacted the prognosis of patients hospitalized by COVID-19. Objective: To establish the association between in-hospital isolation of MDR bacteria and mortality in patients hospitalized for COVID-19 at the Cayetano Heredia Hospital. Methods: A retrospective observational cohort study was performed. Absolute and relative frequencies were used for descriptive analysis. Chi-square test and relative risk (RR) were used to evaluate the association between MDR isolation and mortality, considering a value of p <0.05 as statistically significant. Results: Of the 2273 patients hospitalized for COVID-19, 60,9% were male, median age was 57,0 [RIC: 45,0; 67,0]. The overall incidence of microbiological isolation was 49,7 and of MDR isolates was 27,3 per 1000 hospitalized patients. The most frequently isolated pathogens were Acinetobacter spp. (44,2%) and Pseudomonas spp. (9,3%). Both pathogens presented higher frequencies of multidrug resistance. No statistically significant association was found between MDR isolates and in-hospital mortality (RR = 1,51; 95% CI = 0,69 – 3,0; p = 0,274). Conclusion: No significant association was found between having an MDR bacterial isolation and in-hospital mortality. The most frequent pathogens were Acinetobacter spp. and Pseudomonas spp. which also presented the highest proportions of multidrug resistance.
