Abstract：
The objective of this study was to assess the impact of microbiological test reports that provide specific written recommendations on the appropriate management of Staphylococcus aureus bacteremia (SAB). We performed a retrospective analysis of laboratory and clinical data of all SAB patients treated at one German University hospital, 2012-2015. Among 467 included patients, methicillin-resistant S. aureus (MRSA) accounted for 15.2% of all SAB cases. All-cause in-hospital mortality was 25.2%, and was significantly elevated in individuals aged >55 years, in MRSA bacteremia and if the source of infection remained unidentified. Focus identification was achieved in 71.1%, with the most prevalent foci being catheter-associated bloodstream infection (23.1%), soft tissue infection (15.4%), osteomyelitis (5.1%) and endocarditis (4.9%). Standardized written recommendations on microbiological test reports led to a significant increase of transesophageal echocardiography, additional imaging studies for focus identification and more frequent follow-up blood cultures, but no significant effect on mortality was observed.
