Description of Research: Carol Chenoweth

Our research centers around the epidemiology of healthcare associated infections and antibiotic resistant organisms:

Healthcare-associated infections
The major focus of our research has been the epidemiology and prevention of hospital associated infections in high risk patient populations. Our analysis of candidemia in a children’s hospital identified that hyperalimentation was an independent risk factor for candidemia in children. In a similar type of study, mucositis was identified as the key risk factor for the development of anaerobic bacteremia in bone marrow transplant recipients. Two cohort studies have highlighted the prevalence of nosocomial infections in patients undergoing high risk procedures, such as extracorporeal membrane oxygenation or left ventricular assist devices. We have two current studies near completion on healthcare-associated infections in the home setting.

Emerging antibiotic resistance
We have an interest in antibiotic resistant organisms in community and hospital pathogens, especially antibiotic resistant enterococci. A study of vancomycin-resistant enterococcus colonization in patients awaiting liver transplantation is in final stages of manuscript preparation. In addition, we are participating in a multicenter study to evaluate efficacy of control measures for prevention of spread of vancomycin-resistant enterococci and methicillin-resistant staphylococci in the ICU setting.
