Abstract :

Due to the elevated number of nosocomial infections and its relation with intra-hospital morbidity and mortality levels, it is crucial to evaluate the responsible agents in order to improve patients' care. This is an observational, retrospective and transversal study performed at the Hospital da Santa Casa de Misericórdia de Vitória, involving 511 patients infected between July 2014 and June 2016. Data on blood culture samples were collected from the database of the Hospital Infection Control Committee (CCIH). For blood culture, sheep blood agar (SBA), chocolate agar and MacConkey agar (MAC), after culture in an automated blood culture system were used. Microbial identification and susceptibility profile evaluation were performed using the MicroScan auto SCAN- 4 (Beckman Coulter®) automated system. The study describes four bacterias in detail: Acinetobacter spp., Klebsiella pneumoniae, Pseudomonas aeruginosa and S. aureus. The study found that the least active antimicrobials against S. aureus were nalidixic acid and ampicillin, while the most active were amikacin and cefazolin. Secondly, the least active antimicrobials against Acinetobacter spp. were aztreonam and ertapenem, whereas the most active were polymyxin and rifampicin. Furthermore, the least active antimicrobials against K. pneumoniae were ampicillin and ampicillin/sulbactam, while the most active were amikacin and cefoxitin. Finally, the least active antimicrobials against P. aeruginosa were ceftriaxone and cefotaxime, while the most active were erythromycin and polymyxin. Physicians often have difficulty in establishing the susceptibility profile of the etiologic agent of an infection. Thus, knowledge about antimicrobial resistance from the hospital is fundamental, improving clinical management of patients.
