Infection control refers to activities performed to reduce the risk of infections. Although infection control is a long-standing activity for hospitals, it does not have well-established comparative indicators. We follow CDC (Centers for Disease Control and Prevention) guidelines for the identification and public reporting of infections. Like other hospitals, we practice universal precautions to reduce infections, but we collect systematic data only for selected infections ("targeted surveillance") that occur in the pediatric and neonatal intensive care units. Many of the other sections of this report also have infection control indicators. Norton Healthcare performance represents the performance of all the hospitals combined.
