Resumo

Background: Healthcare-associated bacterial infections (HAIs) are of great concern due to the impact on hospitalization length stay, hospital lethality, high costs, and an increase in multi-resistant microorganisms, therefore, it is extremely important to draw preventive action strategies for HAIs. Objectives: To analyze the profile of HAIs in a public university hospital. Methods: This is a cross-sectional and retrospective study, carried out at a hospital between January 1st and December 31st, 2020, which included all patients diagnosed with HAIs through Hospital Infection Control Committee (HICC) data and analysis of patient medical records. Results: 163 patients were diagnosed with HAIs, 50.3% were women, and 49.7% were men. The mean age was 66.4 years (DP=14.6). Regarding the infection site, we have 62 urinary tract infections (34.8%); 58 primary bloodstream infections (32%); 28 surgical site infections (15.7%); of the 178 infections, we have 34 infections of Klebsiella pneumoniae (19.1%), Staphylococcus aureus 29 (16.3%), Escherichia coli 27 (15.2%), Proteus mirabilis 17 (9.6%), Pseudomonas aeruginosa 16 (9%). The most used classes of antibiotics were cephalosporins, aminoglycosides, and quinolones. Furthermore, 66.7% of patients were discharged and 33% died, 73.6% of which were related to HAIs. Conclusion: HAIs has a high impact on patient costs and outcome. The data found can help in the outcome of infected patients and in the reduction of infections based on new measures implemented by the HICC.
