Substance and alcohol use data in the Integrated Data Infrastructure (IDI) report

This technical report has been written for researchers using New Zealand’s Integrated Data Infrastructure (IDI) to undertake research into alcohol and other drugs. In the IDI there are multiple sources of data that contain information on substance and alcohol use.

These data sources are collected for a range of different purposes and the completeness and quality of these data sources may vary. This guide sets out what data on alcohol and other drugs is available in the IDI and how this information can be used to define populations of interest (substance use population and alcohol-use in utero population).
