- 27. Bloodstream infections (C-178) IsErtapenem as Efficacious as Other Carbapenems for Infections Due to ESBL-producing Enterobacteriaceae in All Subgroups of Patients? • Sensitivity analyses using multivariate logistic regression, propensity score and CART analyses were performed in different subpopulations (30-d mortality) • Sensitivity analysis favors other carbapenems in patients with septic shock/severe sepsis (HR: 3.10; 95% CI: 0.86-11.20) • In patients receiving ertapenem, renal failure was a protective factor for 30-day mortality (mortality, 0 vs 27.8%;p=0.08) • Caution is needed when using ertapenem in cases of severe sepsis/septic shock in BSI due to ESBL-E Conclusions • The fact that renal failure have a protective effect for mortality in these patients might be due to increased ertapenem exposure in this population

- #19 Ejemplo del grado de discordancia entre expertos a la hora de evaluar prescripciones antibióticas, en este caso en UCI. Abstract: Background: There is universal awareness of the difficulties faced by doctors when prescribing antimicrobials. Methods: Over a six-month period patients hospitalized in the ICU and under treatment with antibiotics and/or antifungals were eligible to participate in the study. The data were assessed by two infectious diseases specialists. Once completed, all case forms were sent independently to both evaluators (TZSC and ARM) by e-mail. Based on the data received, the evaluator completed a form automatically generated on the e-mail and returned it to the original mailbox for further analysis. We assessed the level of agreement between infectious disease specialists and the physicians directly responsible for the decision to begin antimicrobial therapy, as well as to assess the appropriateness of the regimen prescribed. Results: Among the antimicrobial regimens prescribed to the 177 patients, 36 % were considered inappropriate by specialist #1 and 38 % were considered inappropriate by specialist #2. We found 78 % agreement by at least one of the infectious disease specialists with the prescribed antimicrobial regimen, and in 49 % of cases both specialists agreed with the prescribed regimen. Both disagreed with the prescribed regimen in 22 % of the cases and they disagreed between themselves in 29 % of the cases. Conclusion: This study highlights the difficulties in prescribing effective empirical antimicrobial therapy - they are of such magnitude that even two specialists in infectious diseases, well acquainted with our hospital’s resistance patterns and our patients’ profiles have considerable disagreement.
