P010: Bloodstream infections by drug-resistant organisms in a secondary hospital

DR-BSI caused by Acitetobacter carbapenem resistant and 3 DR-BSI by P. aeruginosa carbapenem resistant. Median time to diagnosis for DR-Nosocomial BSI was 14 days (IQR), 7-35 days after hospital admission. For Gram-negative was 11 days (7.5-31.5) and for Grampositive 19 days (7-29). Only 31.7% of DR-BSI received appropriate initial empirical antimicrobial therapy versus 73.5% of non DR-BSI (p<0.001). More than one third (36.5%) of the episodes occur with significant systemic response (severe sepsis or septic shock). The crude mortality rate was 25.4 % (p<0.001). If the patient developed severe sepsis or septic shock crude mortality rose to 52.2%. Conclusion
