Outlier Management Policy

An outlier is identified when an ICU’s SMR falls​ outside of the ‘funnel plot’ for their classification, where control limits are drawn using 95% and 99% confidence intervals around the mean SMR of the group. An ICU is only considered an outlier if it’s annual SMR falls above the upper outer control limit (99% confidence interval). ​

A structured process of analysis and reporting is undertaken to identify data quality and case mix issues that may explain the findings. ​An Outlier Working Group (OWG) provides the clinical and statistical oversight of the review process for the APD as does the ANZPIC Registry Clinical Advisory Committee (ARCAC) for the ANZPIC Registry.
