Ambulatory sensitive (avoidable) hospital admissions

Data to help DHBs with reporting against system integration performance measure - SI1/SLM Ambulatory sensitive (avoidable) hospital admissions (ASH admissions)

Updated 10 March 2023.

Please note that the denominator (population) changed for the purposes of  2015/16 reporting. Population estimations from Census data are now being used rather than PHO enrolment data. As such, ASH rates may differ from the rates noted in datasets from previous years. When making comparisons against previous performance, please use the time series in the latest reports to ensure you are using a consistent approach.

Furthermore, it is important to note that due to the unusually long time between the 2006 census and the 2013 census, there is a small step in population estimates between 2012/13 and 2013/14. This reflects the fact that the 2013/14 and later population estimates are more accurate than projections from the 2006 census.

The Ministry discovered an issue assigning some events to Canterbury DHB of service in May 2018. This issue was corrected for all reports released since May 2018. However, prior reports have not been amended to take this into account.

This information is also available in the Toolkits section of the Ministry’s non-financial Quarterly Reporting website.
