Data analysis

NCIRS have been leaders in the use of surveillance data to evaluate and track trends in morbidity due to vaccine preventable diseases in Aboriginal people.

Since 2004, NCIRS has produced regular reports on vaccine preventable diseases (VPDs) and vaccination coverage in Aboriginal and Torres Strait Islander people. These reports bring together relevant routinely collected data on notifications, hospitalisations and deaths, and childhood and adult vaccination coverage.

Production of these reports has required the development and/or application of new methods to determine the quality and completeness of Aboriginal data. Establishing minimum criteria of data quality has led to the availability of improved data from more Australian states and territories. This has allowed wider use of data and subsequent publication through these reports. While the Australian Institute of Health and Welfare has developed methods for assessing data quality for hospitalisations in Aboriginal people, NCIRS is the only organisation to systematically apply similar standards to VPD hospitalisations and vaccination coverage.

Reports are modelled on the national surveillance reports (also produced by NCIRS) and provide a comparison of VPDs and vaccination coverage in Aboriginal and non-Aboriginal Australians and a focus on the quality of Aboriginal health data. The latest (third) report, which covered the period 2006–2010, was published as a supplement issue of Communicable Diseases Intelligence in December 2013.

The reports have also been modified for use by Aboriginal health workers and other staff without clinical experience working in Aboriginal health (published as Vaccination for our Mob).
