A matched case-control study was performed to identify predictors of mortality among patients (n = 46) with community-onset infections due to extended-spectrum beta-lactamase-producing Escherichia coli in Thailand. The crude mortality rate was 30%. By multivariable analysis, community-onset bloodstream infection due to extended-spectrum beta-lactamase-producing E. coli was the sole predictor of mortality (adjusted odds ratio, 41.3 [95% confidence interval, 4.3-69.4]; [P= .001).
Multivariable Cox regression showed patients with Genitourinary infection (HR: 2.23, p = 0.04) and Implantable devices (HR 11.30, p = 0.17) were at higher risk of death.
Conclusion:The site-specific infection has shown to be a significant predictor of mortality in our study, these factors should be taken into consideration and needs further evaluation to understand their specific role in adverse outcome among a cohort of patients diagnosed with sepsis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
