Annual Quality Report

The CMP Annual Quality Report is a publically available report that compares risk-adjusted mortality and key quality indicators at various levels (for critical care units, hospitals, Trusts and Critical Care Networks) for the period 1 April to 31 March annually.

ICNARC makes results from the CMP public to provide a valuable insight into the quality of adult, general and specialist critical care.

Outlier management

An outlier is a result that is statistically significantly further from the expected comparator value than would usually occur by chance alone.

We have developed guidance to ensure that potential outliers are identified through the processes of national clinical audit. The guidance document sets out the actions that we take when data indicate that results for a critical care unit significantly deviate from the expected value.

Our guidance on the detection and management of outliers is based on Department of Health recommendations on the 'Detection and management of outliers' and supersedes our previous policy.

For more information on the detection and management of outliers, please see related files.
