NVR Outlier
This document sets out the process by which consultant and unit level performance will be assessed within the National Vascular Registry (NVR). It is designed to provide transparency about data handling and analysis, and a robust process for managing hospitals/consultants with indicator values that fall outside the expected range of performance (i.e. are flagged as an “outlier”).
The timeframe for the current performance indicators are below:
