Road crash trauma amongst Aboriginal and Torres Strait Islander people in New South Wales Andrew Graham, Hassan Raisianzadeh, Richard Thiele, Sarah Pont and Rajah Supramaniam AIPN November 2017 - Ballarat October 2017
Delivering the Strategy • Aboriginal Road Safety Action Plan: an initiative under the NSW Road Safety Strategy 2012 - 21 • Need for robust, relevant and reliable information on Aboriginal road safety experience 2
CRS Health Linkage Project • No solid evidence on Aboriginal road safety trauma in NSW until 2014 • Identification of Aboriginal road users proved to be a complex process • Hospital records a rich source of Aboriginality identification • Challenge was how to use the evidence from Health to identify Aboriginality A data linkage project was set up to answer many research questions including: ‘H ow are crashes and injuries distributed demographically across the various sectors of the community, including Aboriginal people ?’ 3
Linkage project identifies Aboriginal people Ever Majority identified identified ✓ ✓ Ministry of Health Algorithm identified ✓ Non- Aboriginal Aboriginal

Detailed profile 2011 to 2015: Who, Where & When Aboriginal casualties tended to be slightly younger; the distribution was similar by gender. Aboriginal serious casualties were more likely to occur outside of the Sydney-Newcastle-Wollongong greater conurbation (more than half of fatalities were in the Northern and Western RMS Regions) and on unclassified roads. Between midnight and 6am the Aboriginal age-standardised serious injury rate was double that of the non-Aboriginal rate. 11
Detailed profile 2011 to 2015: How & Why Off path on straight and off path on curve or turning crashes were more commonly involved among Aboriginal road user serious casualties. Illegal alcohol, fatigue, speeding, restraint non-usage and unauthorised driving were more commonly involved among Aboriginal road user casualties. 12
