Background and Objectives: To characterize the main Healthcare-Associated Infections (HAIs) in a public teaching hospital. Methods: This is a descriptive, retrospective, cross-sectional, quantitative epidemiological study. It was performed through analysis of internal documents of the Hospital Infection Control Service (Portuguese acronym: SCIH) on bloodstream infections, surgical site infections and hospital pneumonia in patients admitted to the institution between May 2017 and May 2018. Results: During the study period, were reported 846 cases of HAI. Out of that total, 582 were analyzed, of which 298 (51.21%) were men and 284 (48.79%) were women. Among the most prevalent infections, 197 (23.28%) were surgical site infections, 183 (21.63%) were ventilator-associated pneumonia, and 164 (19.38%) were primary bloodstream infections. The predominant microorganisms found after microbiological analysis were: Acinetobacter spp. in 33 (21%) infections, followed by Pseudomonas spp. in 30 (19.1%) and Enterobacter spp. in 17 (10.8%). Regarding medical specialties with higher prevalence of HAIs, there were 218 (25.76%) infections in neurology, 157 (18.55%) in general practice and 154 (18.20%) in pediatrics. Conclusion: Surgical site infections, mechanical ventilator-associated pneumonia and primary bloodstream infection were prevalent. Laboratory support was fundamental in the identification of pathogenic microorganisms, and those of higher incidence among all HAIs were Acinetobacter spp., Pseudomonas spp. and Enterobacter spp. In the analysis by specialty, neurology had a significant predominance in healthcare-associated infections.
