Abstract Background Staphylococcus aureus bacteremia (SAB) remains the leading cause of bloodstream infections and is associated with 20–40% mortality. Past studies demonstrated that Infectious Diseases (ID) consultation is associated with better adherence to quality of care indicators (QCIs), including follow-up blood cultures, echocardiography, early source control, and appropriate choice and duration of antibiotics. A 2014 quality improvement project at Medstar Washington Hospital Center (MWHC) by Narsana et al. showed significantly better adherence to SAB QCIs among patients with ID consults and a non-significant trend towards lower mortality. In 2015, MWHC instituted a policy advocating ID consultation for all SAB patients, and active surveillance was performed by the ID Section to offer prompt consults prospectively. Our study aimed to assess the impact of this policy and the proactively offered ID consults on adherence to SAB QCIs and mortality rates amongst patients with SAB with and without ID consults. Methods We retrospectively reviewed 557 patients diagnosed with SAB between July 1st, 2015 - June 30th, 2018. Data included follow-up blood cultures, echocardiography, presence of a focal source of infection, use of appropriate antibiotics, measurement of vancomycin levels, duration of therapy, death during hospitalization, and presence of an ID consultation. Chi-Square and Fisher exact tests, and t-test and Wilcoxon rank sum test were used to analyze categorical and continuous variables, respectively. Results A total of 513 patients were included in the analysis, 88% (n=453) of whom had ID consultations. Patients with ID consultations were more likely to have a focal source of infection (84% vs. 50%, p < 0.0001), echocardiography (97% vs. 56%, p < 0.0001), use of a beta-lactam antibiotic for methicillin-susceptible S. aureus (90% vs 65%, p < 0.0001), and a longer duration of therapy (33 vs 9 days, p< 0.0001). Mortality was lower among patients with ID consults (16% vs. 23%, p=0.1495), but the difference was not statistically significant. Table 1 Conclusion Our study demonstrates that ID consultation is associated with better adherence to SAB QCIs, with a trend towards lower mortality. Hospital systems should support mandatory ID consultation for patients with Staphylococcus aureus bacteremia. Disclosures All Authors: No reported disclosures

Abstract Background Recommended management of Staphylococcus aureus bacteremia (SAB) includes follow up blood culture sets (BCs) to determine the duration of bacteremia. Duration of bacteremia is an important prognostic factor in SAB and follow up BCs have a critical role in differentiation of uncomplicated and complicated SAB. However, intermittent negative BCs occur in SAB. Clinical guidelines for SAB management do not specify an approach to follow up BCs collection or define the number of negative BCs required to demonstrate resolution of bacteremia. This study assessed the frequency of intermittent negative BCs in SAB and used these finding to formulate a recommendation for collection of follow up BCs. Methods This retrospective study reviewed 1071 episodes of SAB. Clinical and microbiological data including the duration of bacteremia and the occurrence of intermittent negative BCs (those preceded and followed by positive cultures) were considered. Results Intermittent bacteremia occurred in 13% (140/1071) of episodes. A single negative BCs on days 1-3 had a predictive value of 87-93% for resolution of bacteremia although this was improved if all BCs collected within the same day were considered. Conclusions Intermittent negative BCs are common in SAB. Given this we would not recommend accepting a single negative BCs as demonstrating resolution of the bacteremia. This is particularly important if a patient is to be classified as having an uncomplicated SAB.

Abstract Historically, intravenous (IV) antibiotics have been the cornerstone of treatment for uncomplicated Staphylococcus aureus bacteremia (SAB). However, IV antibiotics are expensive, increase the rates of hospital readmission, and can be associated with catheter-related complications. As a result, the potential role of oral antibiotics in the treatment of uncomplicated SAB has become a subject of interest. This narrative review article aims to summarize key arguments for and against the use of oral antibiotics to complete treatment of uncomplicated SAB and evaluates the available evidence for specific oral regimens. We conclude that evidence suggests that oral step-down therapy can be an alternative for select patients who meet the criteria for uncomplicated SAB and will comply with medical treatment and outpatient follow-up. Of the currently studied regimens discussed in this article, linezolid has the most support, followed by fluoroquinolone plus rifampin.

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.

Abstract Background Staphylococcus aureus bacteremia (SAB) is associated with 30-day all-cause mortality rates approaching 20–30%. The purpose of this case–control study was to evaluate risk factors for 30-day mortality in patients with SAB at a community hospital. Methods As part of an antimicrobial stewardship program (ASP) initiative mandating Infectious Diseases consultation for episodes of SAB, our ASP prospectively monitored all cases of SAB at a 341-bed community hospital in Jefferson Hills, PA from April 2017–February 2019. Cases included patients with 30-day mortality from the initial positive blood culture. Only the first episode of SAB was included; patients were excluded if a treatment plan was not established (e.g., left against medical advice). Patient demographics, comorbidities, laboratory results, and clinical management of SAB were evaluated. Inferential statistics were used to analyze risk factors associated with 30-day mortality. Results 100 patients with SAB were included; 18 (18%) experienced 30-day mortality. Cases were older (median age 76.5 vs. 64 years, P < 0.001), more likely to be located in the intensive care unit (ICU) at time of ASP review (55.6% vs. 30.5%, P = 0.043), and less likely to have initial blood cultures obtained in the emergency department (ED) (38.9% vs. 80.5%, P < 0.001). Variables associated with significantly higher odds for 30-day mortality in univariate analysis: older age, location in ICU at time of ASP review, initial blood cultures obtained at a location other than the ED, and total Charlson Comorbidity Index (CCI). Variables with P < 0.2 on univariate analysis were analyzed via multivariate logistic regression (Table 1). Conclusion Results show that bacteremia due to MRSA and total CCI were not significantly associated with 30-day mortality in SAB, whereas older age was identified as a risk factor. Patients with initial blood cultures obtained at a location other than the ED were at increased odds for 30-day mortality on univariate analysis, which may raise concern for delayed diagnosis.

Purpose: Staphylococcus aureus is a leading cause of bacteremia with a 30-day mortality of 20%. This study evaluated outcomes after implementation of a pharmacist-driven Staphylococcus aureus bacteremia (SAB) initiative in a community hospital. Methods: This retrospective cohort analysis compared patients admitted with SAB between May 2015 and April 2018 (intervention group) to those admitted between May 2012 and April 2015 (historical control group). Pharmacists were notified of and responded to blood cultures positive for Staphylococcus aureus by contacting provider(s) with a bundle of recommendations. Components of the SAB bundle included prompt source control, selection of appropriate intravenous antibiotics, appropriate duration of therapy, repeat blood cultures, echocardiography, and infectious diseases consult. Demographics (age, gender, and race) were collected at baseline. Primary outcome was in-hospital mortality. Compliance with bundle components was also assessed. Results: Eighty-three patients in the control group and 110 patients in the intervention group were included in this study. Demographics were similar at baseline. In-hospital mortality was lower in the intervention group (3.6% vs. 15.7%; p = 0.0033). Bundle compliance was greater in the intervention group (69.1% vs. 39.8%; p < 0.0001). Conclusions: We observed a significant reduction in in-hospital mortality and increased treatment bundle compliance in the intervention cohort with implementation of a pharmacist-driven SAB initiative. Pharmacists’ participation in the care of SAB patients in the form of recommending adherence to treatment bundle components drastically improved clinical outcomes. Widespread adoption and implementation of similar practice models at other institutions may reduce in-hospital mortality for this relatively common and life-threatening infection.
