213. Assessment of Compliance with Order Set and Bundle for Management of Staphylococcus aureus Bacteremia

Abstract

Background Staphylococcus aureus (S. aureus) is an aerobic gram-positive coccus that causes a variety of infections. S. aureus bloodstream infections, also known as bacteremias, have significant morbidity and mortality and are difficult to eradicate. A single-center study showed a 9.4% recurrence rate for S. aureus bacteremia, despite adequate treatment. The Infectious Disease Society of America (IDSA) recognizes the seriousness of S. aureus infections, particularly methicillin-resistant S. aureus (MRSA), and has released guidance for treatment of these infections. Guidance for S. aureus bacteremias include identification and removal of the source and early optimization of antibiotics. Serial imaging and laboratory monitoring, including repeat blood cultures, are also necessary to establish the duration of therapy, ensure microbiologic eradication, and reduce the risk of long-term complications. Due to the complexity of S. aureus bacteremia, early involvement of infectious diseases (ID) specialists is strongly recommended. MethodsThis retrospective, single-center study was designed to evaluate the current management of S. aureus bacteremias, including compliance to the elements of the S. aureus order set and bundle. Patients 18 years and older who had a positive blood culture for S. aureus were included in this study. Recurrence of S. aureus infection was assessed at 6 months. Data was analyzed to compare patients with and without ID consults.ResultsEighty-four patients met inclusion criteria. ID consultation resulted in a higher percentage of patients achieving 100% compliance with the bundle elements compared to patients without ID consults (73% vs 25%, respectively; p=0.009). For further breakdown of compliance see Table 1. No statistical difference was detected in recurrence rates (11% vs 33%, respectively; p=0.18) or mortality (8% vs 25%, respectively; p= 0.17) possibly due to the small sample size. Table 1. Outcomes ConclusionID specialist involvement for the treatment of S. aureus bacteremia resulted in greater compliance with the S. aureus bacteremia bundle. No statistical difference in recurrence or mortality rates was detected.Disclosures All Authors: No reported disclosures
