My research focuses on antibiotic use and infection control in pediatric intensive care units (PICUs). The majority of PICU patients receive antibiotics for suspected bacterial infections that were not definitively confirmed by laboratory tests. Because the recommendations about how long to use antibiotics in such situations are not clear, PICU physicians tend to prolong antibiotic treatment unnecessarily. This overuse of antibiotics is associated with toxicity and infections caused by antibiotic-resistant bacteria. To reduce antibiotic overuse in PICUs, I am working on the development of a tool that will indicate when it is safe to stop antibiotics in PICU patients. This involves studying how PICU physicians make decisions about antibiotic use and the ability of clinical findings and diagnostic tests to predict infection cure in PICUs. Finally, I also study the determinants of hospital-acquired infections, usually caused by antibiotic-resistant bacteria, and strategies that can be used to decrease their rates.
