Abstract

Using an algorithm including both enzyme immunoassay (EIA) and nucleic acid amplification (NAAT) for Clostridium difficile infection (CDI) diagnosis, we found that the use of NAAT versus EIA almost doubled our hospital-onset CDI laboratory-identified (LabID) event standardized infection ratio (SIR). We recommend that the current risk adjustment approach be modified.
