Abstract
Objective: To analyze the incidence of primary bloodstream infections associated with central venous catheters in an Intensive Care Unit, identifying the microorganisms involved and their antimicrobial resistance profiles. Methods: This was a quantitative, retrospective, and longitudinal study conducted in an Intensive Care Unit, including a population of critically ill patients using central venous catheters. Data were collected over a three-year period from clinical records, epidemiological surveillance reports, and institutional microbiological results, using hospital databases and infection control systems as research instruments. Results: Variability in the incidence density of primary bloodstream infections was observed during the analyzed period, with episodes compatible with outbreaks and a high frequency of multidrug-resistant microorganisms. The findings highlight the relevance of these infections in the intensive care setting, associated with the complexity of critically ill patients and the increasing antimicrobial resistance, directly impacting patient safety and clinical outcomes. Conclusion: The main strength of the study lies in the longitudinal analysis of epidemiological and microbiological data, enabling a better understanding of the profile of primary bloodstream infections in the ICU. Limitations include the retrospective design and the reliance on secondary institutional records.
