Definitions of key terms used in the NNIS System.
For valid comparisons with the published NNIS nosocomial infection rates, hospitals must define data elements in the same way. Definitions for infections, risk factors, and populations monitored are specified in the NNIS System, but thus far only infection definitions and the list of NNIS operative procedure categories have been published. This article defines other key terms used in the NNIS System.
