Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is a serious infection that can result in significant morbidity and mortality. A retrospective cohort study was conducted to determine the predictors of mortality in patient with MRSA bacteremia correlating with clinical, phenotypic and genotypic characteristics of the relevant strains. Most of the bacteremia cases were healthcare-associated (P
Methicillin-resistant Staphylococcus aureus has emerged as an important cause of nosocomial infections in recent years. During 1988 in the Department of Surgery of the University Hospital in Kuala Lumpur, Malaysia, 148 patients were shown to be infected or colonized with these organisms. The patients at risk were those who stay in hospital for greater than 14 days, those over 50 years of age, patients who underwent neurosurgery, cardiothoracic surgery, or were admitted with major burns. Of the 148 patients, 78 (52.7%) were clinically infected, the remaining 70 being colonized. A total of 28 patients died (18.9%) but only five (3.4%) as a direct result of this infection. The estimated annual cost of controlling the organism was found to be approximately MR$250,000. (50,000 pounds). This nosocomial infection therefore represents a serious problem, especially in developing countries where health funding and health facilities are limited.
Staphylococcus aureus left-sided native valve infective endocarditis (LNVIE) has higher complication and mortality rates compared with endocarditis from other pathogens. Whether echocardiographic variables can predict prognosis in S aureus LNVIE is unknown.
