Practice patterns among survey respondents on the diagnostic evaluation and management of Staphylococcus aureus bacteremia (SAB). A, Diagnostic workup routinely performed in the evaluation of a patient with SAB. B, Respondents indicating they would perform transthoracic echocardiogram (TTE) on every patient but only perform transesophageal echocardiogram (TEE) under these selected circumstances (n = 473). C, Management of patient with methicillin-resistant Staphylococcus aureus endocarditis and persistent SAB on day 6 of vancomycin, with therapeutic trough and vancomycin MIC of .5 mg/L. D, Factors influencing decision to extend duration of therapy from 2 weeks to 4–6 weeks assuming negative echocardiography (TTE and/or TEE). Abbreviations: Abd, abdominal; cx, culture; CT, computed tomography; MRI, magnetic resonance imaging; MRSA, methicillin-resistant Staphylococcus aureus; TEE, transesophageal echocardiogram; TTE, transthoracic echocardiogram. *Among 222 respondents who commented on other clinical factors that would prompt TEE, common responses included presence of cardiac device or prosthetic valve (58 [26%]); clinical suspicion for infective endocarditis including embolic phenomenon or metastatic infection (43 [19%]); or TEE results would change management (eg, duration of therapy, surgical management) (36 [16%]).
