Abstract
SANCHEZ-PARDO, Santiago; OCHOA-DIAZ, Andrés Felipe; RODRIGUEZ, Reynaldo and ROJAS, Elsa Marina. PRESENTATION OF RESISTANT BACTERIA IN BLOOD CULTURES IN PATIENTS WITH MEDICAL PATHOLOGIES IN A THIRD LEVEL HOSPITAL. Investig. andina [online]. 2019, vol.21, n.39, pp.153-167. Epub Feb 01, 2021. ISSN 0124-8146.
Introduction:
Bacteremia affects patients in the hospital, with mortality rates reported in 35%. Microorganisms that produce beta- lactamases 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%.
