Survival following Staphylococcus aureus bloodstream infection: A prospective multinational cohort study assessing the impact of place of care. J Infect. 2018 Dec;77(6):516-525.http://hdl.handle.net/10668/12902Staphylococcus aureus bloodstream infection (SAB) is a common, life-threatening infection with a high mortality. Survival can be improved by implementing quality of care bundles in hospitals. We previously observed marked differences in mortality between hospitals and now assessed whether mortality could serve as a valid and easy to implement quality of care outcome measure. We conducted a prospective observational study between January 2013 and April 2015 on consecutive, adult patients with SAB from 11 tertiary care centers in Germany, South Korea, Spain, Taiwan, and the United Kingdom. Factors associated with mortality at 90 days were analyzed by Cox proportional hazards regression and flexible parametric models. 1851 patients with a median age of 66 years (64% male) were analyzed. Crude 90-day mortality differed significantly between hospitals (range 23-39%). Significant variation between centers was observed for methicillin-resistant S. aureus, community-acquisition, infective foci, as well as measures of comorbidities, and severity of disease. In multivariable analysis, factors independently associated with mortality at 90 days were age, nosocomial acquisition, unknown infective focus, pneumonia, Charlson comorbidity index, SOFA score, and study center. The risk of death varied over time differently for each infective focus. Crude mortality differed markedly from adjusted mortality. We observed significant differences in adjusted mortality between hospitals, suggesting differences in quality of care. However, mortality is strongly influenced by patient mix and thus, crude mortality is not a suitable quality indicator.enBacteremiaMortalityObservational studyQuality measuresStaphylococcus aureusAdultAgedAged, 80 and overAnti-Bacterial AgentsBacteremiaComorbidityCross InfectionFemaleGermanyHumansInternationalityMaleMiddle AgedPatient CareProportional Hazards ModelsProspective StudiesRepublic of KoreaRisk FactorsSpainStaphylococcal InfectionsStaphylococcus aureusSurvival AnalysisTaiwanTertiary Care CentersUnited Kingdomresearch article30179645Restricted AccessInfección del torrente sanguíneo por Staphylococcus aureusPaquete de calidad asistencialMortalidad hospitalariaCuidados terciariosStaphylococcus aureus resistente a meticilinaNeumoníaInfección nosocomialScore de falla orgánica secuencialVariación entre centros10.1016/j.jinf.2018.08.0151532-2742http://sro.sussex.ac.uk/id/eprint/78638/5/ISAC_Survival%20as%20quality%20measure%20in%20SAB-JoI-v22.pdf
