Staphylococcal infections, general infectious diseases, osteomyelitis, catheter-related infections.
My research interests center around the epidemiology and prevention of healthcare-associated infections. Approximately 5-8% of patients admitted to the hospital will acquire a healthcare-associated infection. These infections result in increased morbidity and mortality, prolonged hospital stays, and increased healthcare costs.
I am interested in developing methods to prevent the spread of antimicrobial-resistant bacteria among hospitalized patients. I have participated in several multicenter trials to test these interventions, such as bathing ICU patients with chlorhexidine-based products to prevent methicillin-resistant S. aureus (MRSA) infections. I have conducted several local studies testing methods to prevent common healthcare-associated infections, such as catheter-associated bloodstream infections and surgical site infections. Finally, I am involved in understanding infectious complications of surgical procedures, such as placement of implantable cardiac devices, using longitudinal administrative claims datasets.
