Prediction model to identify patients with Staphylococcus aureus bacteremia at risk for methicillin resistance.

Objectives: To identify institution-specific risk factors for MRSA bacteremia and develop an objective mechanism to estimate the probability of methicillin resistance in a given patient with Staphylococcus aureus bacteremia (SAB).

Design: A cohort study was performed to identify institution-specific risk factors for MRSA. Logistic regression was used to model the likelihood of MRSA.

Outcomes analysis of delayed antibiotic treatment for hospital-acquired Staphylococcus aureus bacteremia.

The objective of this study was to determine the effect of delayed therapy on morbidity and mortality associated with nosocomial Staphylococcus aureus bacteremia. The study included all episodes of S. aureus bacteremia that developed >2 days after hospital admission during 1999 to 2001.

Clinical outcomes for patients with bacteremia caused by vancomycin-resistant enterococcus in a level 1 trauma center.

To assess the degree of morbidity and mortality attributable to vancomycin resistance in enterococcal bacteremia (EB), a matched case-control study was conducted. Patients with bacteremia due to vancomycin-resistant enterococcus (VRE) were matched to control patients with bacteremia due to vancomycin-susceptible enterococcus. During 1996--2000, 65 patients with cases of clinically significant VRE bacteremia were identified, and 53 of these patients were successfully matched.
