Description:Updated April 2022
The Standardized Utilization Ratio (SUR) is the primary summary measure used by the National Healthcare Safety Network (NHSN) to compare device utilization at the national, state, or facility level by tracking central line, urinary catheter, and ventilator use. Tracking device use in healthcare settings is essential to measuring exposure for device-associated infections. Highlighting the SUR as part of the new baseline project, this document is intended to serve as both guidance for those who are new to this metric, as well as a useful reference for more experienced infection prevention professionals.
