Abstract Background Discordance between in vitro susceptibility and empiric antibiotic therapy is inextricably linked to antibiotic resistance and decreased survival in bloodstream infections (BSI). However, its prevalence, patient- and hospital-level risk factors, and impact on outcome in a large cohort and across different pathogens remain unclear. Methods We examined in vitro susceptibility interpretations for bacterial BSI and corresponding antibiotic therapy among inpatient encounters across 156 hospitals from 2000 to 2014 in the Cerner Healthfacts database. Discordance was defined as nonsusceptibility to initial therapy administered from 2 days before pathogen isolation to 1 day before final susceptibility reporting. Discordance prevalence was compared across taxa; risk factors and its association with in-hospital mortality were evaluated by logistic regression. Adjusted odds ratios (aOR) were estimated for pathogen-, patient- and facility-level factors. Results Of 33,161 unique encounters with BSIs, 4,219 (13%) at 123 hospitals met criteria for discordant antibiotic therapy, ranging from 3% for pneumococci to 55% for E. faecium. Discordance was higher in recent years (2010–2014 vs. 2005–2009) and was associated with older age, lower baseline SOFA score, urinary (vs. abdominal) source and hospital-onset BSI, as well as ≥500-bed, Midwestern, non-teaching, and rural hospitals. Discordant antibiotic therapy increased the risk of death [aOR = 1.3 [95% CI 1.1–1.4]). Among Gram-negative taxa, discordant therapy increased risk of mortality associated with Enterobacteriaceae (aOR = 1.3 [1.0–1.6]) and non-fermenters (aOR = 1.7 [1.1–2.5]). Among Gram-positive taxa, risk of mortality from discordant therapy was significantly higher for S. aureus (aOR = 1.3 [1.1–1.6]) but unchanged for streptococcal or enterococcal BSIs. Conclusion The prevalence of discordant antibiotic therapy displayed extensive taxon-level variability and was associated with patient and institutional factors. Discordance detrimentally impacted survival in Gram-negative and S. aureus BSIs. Understanding reasons behind observed differences in discordance risk and their impact on outcomes could inform stewardship efforts and guidelines for empiric therapy in sepsis.

Appropriate choice of empiric antibiotic therapy, in line with local guidelines, improves outcome for children with infection, while reducing adverse drug effects, cost, and selection of antimicrobial resistance. Data from national point prevalence surveys showed compliance with local prescribing guidelines at our hospital was suboptimal. A team with representatives from the pharmacy, microbiology and emergency departments collaborated with prescribers to improve the quality of empiric antibiotic prescribing. The project aim was, using the ‘Model for Improvement’, to ensure ≥90% of children admitted via the Emergency Department (ED) and commenced on antibiotic therapy, have a documented indication and a choice of therapy in line with local antimicrobial guidelines.MethodResults of weekly audits of the first ten children admitted via ED and started on antibiotics were fed back to prescribers. Front line ownership techniques were used to develop ideas for change, including; regular antibiotic prescribing discussion at Monday morning handover meeting, antibiotic ‘spot quiz’ for prescribers, updates to prescribing guidelines (along with improved access and promotion of prescribing app), printed ID badge guideline summary cards, reminders and guideline summaries at point of prescribing in ED.Collection of audit data initially proved challenging, but was resolved through a series of rapid PDSA cycles. Initial support from ED consultants and other ED staff facilitated establishment of the project. Presentation of weekly run charts to prescribers fostered considerable support among consultants and non-consultant doctors (NCHDs). We saw a shift in perspective from ‘how is your project going?’ to ‘How are we doing?’.ResultsDocumentation of indication and guideline compliance increased from a median of 30% in December 2014/January 2015 to 100% consistently from February 2015 to the present. It is felt that a change in approach to antimicrobial prescribing is now embedded in our hospital culture as this improvement has remained constant through three NCHD changeovers. A comparison of 2014 Antimicrobial expenditure to 2015 figures shows a reduction in expenditure of €101,078.44.ConclusionThis project has inspired other departments to develop local QIPs and has encouraged the surgical teams to lead their own audits in antimicrobial stewardship. An improvement in other areas of antimicrobial prescribing has also been noted e.g. documentation of review date.The initiative has been shared with other hospitals throughout Ireland via presentations at the National Patient Safety Conference, Antimicrobial Awareness day and the Irish Antimicrobial Pharmacist’s Group meeting. It has also been shared at both European and international conferences. The project was a shortlisted finalist for a national healthcare excellence award and has been rolled out as part of a national quality improvement collaborative.

Background It is unclear if a local audit would be useful in providing guidance on how to improve local practice of empiric antibiotic therapy. We performed an audit of antibiotic therapy in bacteremia to evaluate the proportion and risk factors for inadequate empiric antibiotic coverage. Methods This retrospective cohort study included patients with positive blood cultures across 3 hospitals in Hamilton, Ontario, Canada during October of 2019. Antibiotic therapy was considered empiric if it was administered within 24 hours after blood culture collection. Adequate coverage was defined as when the isolate from blood culture was tested to be susceptible to the empiric antibiotic. A multivariable logistic regression model was used to predict inadequate empiric coverage. Diagnostic accuracy of a clinical pathway based on patient risk factors was compared to clinician’s decision in predicting which bacteria to empirically cover. Results Of 201 bacteremia cases, empiric coverage was inadequate in 56 (27.9%) cases. Risk factors for inadequate empiric coverage included unknown source at initiation of antibiotic therapy (adjusted odds ratio (aOR) of 2.76 95% CI 1.27–6.01, P = 0.010) and prior antibiotic therapy within 90 days (aOR of 2.46 95% CI 1.30–4.74, P = 0.006). A clinical pathway that considered community-associated infection as low risk for Pseudomonas was better at ruling out Pseudomonas bacteremia with a negative likelihood ratio of 0.17 (95% CI 0.03–1.10) compared to clinician’s decision with negative likelihood ratio of 0.34 (95% CI 0.10–1.22). Conclusions An audit of antibiotic therapy in bacteremia is feasible and may provide useful feedback on how to locally improve empiric antibiotic therapy.

Staphylococcus aureus is one of the most virulent Gram-positive organisms responsible for a multitude of infections, including bacteremia. Methicillin-resistant Staphylococcus aureus (MRSA) is of special concern in patients with bacteremia. Due to its associated poor clinical outcomes, morbidity, and mortality, the superlative salvage regimen for persistent MRSA bacteremia remains uncertain. An 85-year-old white female presented with persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. Empiric antibiotic therapy with linezolid was initiated prior to blood culture results. Once MRSA bacteremia was confirmed, alternative antibiotic therapy with daptomycin was initiated. Blood cultures remained positive for MRSA despite three days of daptomycin therapy after which ceftaroline was added to the antibiotic regimen. Blood cultures remained positive for MRSA despite seven days of combination therapy with daptomycin and ceftaroline. Salvage therapy was then initiated with daptomycin, linezolid, and meropenem. One day following initiation of salvage therapy, blood cultures revealed no bacterial growth for the remainder of the length of stay. This report supports the effectiveness of salvage therapy consisting of daptomycin, linezolid, and meropenem in patients with persistent MRSA bacteremia.
