Presentación de bacterias resistentes en hemocultivos en pacientes con patología médica en un hospital de tercer nivel

Abstract

Introduction: Bacteremia affects patients in the hospital, with mortality rates reported in 35%. Microorganisms that produce betalactamases of extended spectrum are each time more resistant to antibiotics. Method: Observational and descriptive study in patients older tan 14 years old with positive blood cultures in Hospital Universitario de Santander, between 2014 and 2016. Results: 148 clinic records were analyzed, the mean age was 55.5 years. 51.4% were women. The proportion of resistant germs was of 23.6%, the production of beta-lactamases of extended spectrum in E. coli and K. pneumoniae was 40%. 100% of patients with resistant germs had a rate of severe PITT. S. aureus showed a 50% of resistance to oxacillin. Conclusion: 23.6% of patients had an infection for resistant germs, the most common were E. coli and K. pneumoniae. General mortality was of 30%.
