The Virtual Health Information Network (VHIN) assists researchers to do high quality health research using the Integrated Data Infrastructure (IDI) and other administrative health data. A deeper understanding of the IDI and increased awareness of data quality issues can be gained via website guides (posted below), online discussions on the VHIN Facebook page, analytical code available from VHIN research and meetings about current IDI research (Presentations).

Understanding current practice and systems for analysis of integrated data in the Stats NZ Data Lab – report

This report, by Peter Ellis, scopes the needs and opportunities for information and analytical layers in the IDI, whilst also outlining the current approaches to analysis in the IDI and observations on the analytical environment.

Introduction to Health Research in the IDI courses

The VHIN is offering a new workshop orientation to the StatsNZ IDI (Integrated Data Infrastructure). This one-day course aims to provide the base knowledge and contacts that IDI users will need to maximise the value of this resource for health research. The workshop will cover the major opportunities and issues around using the IDI for health research and include an expert user panel discussion and questions time. Topics include;

  • Orientation to the IDI
  • Research questions and methods for big data
  • Data sharing and useful resources
  • How to get started in the IDI
  • Social license, ethics, and kaitiakitanga
  • The IDI structure, the spine, estimating a population and linkage rates
  • Key information on ethnicity, address, income and health
  • Brief introduction to SQL/SAS/other coding and where to find resources
  • Panel examples of IDI research, followed by question and answer session

The workshop will be held in Wellington and Auckland in February 2018:

A complementary ‘Introduction to data ethics’ course will also be held in Wellington on the day before the VHIN introduction course, on Tuesday the 13th of Feb at the Public Health Summer School. For people interested or involved in data research, the ethics course will provide the opportunity to develop a deeper understanding of ethical, cultural and social licence challenges.

Early bird registration for all courses close on the 18th of December.
