Technical report

There is no direct way to count the number of new stroke and acute coronary syndrome (ACS) events at the national level. To date, Australian Institute of Health and Welfare reports use estimates derived using algorithms based on unlinked national hospitalisation and deaths data. This technical report assesses how well the algorithms function using linked data from the National Integrated Health Services Information Analysis Asset (NIHSI AA). It describes the validation study undertaken to assess the algorithms and the methods for estimating the incidence of stroke and ACS using linked data from the NIHSI AA. All data presented in this report are available through the online supplementary tables available under Data tables
