Measuring Non-Fatal Road Injuries AIPN 2017 Conference, James - PowerPoint PPT Presentation

A National Approach to Measuring Non-Fatal Road Injuries AIPN 2017 Conference, James Harrison Ballarat, 13-15 November Angela Watson 2017 Kirsten Vallmuur Tim Risbey

Background • Data on non-fatal road injuries, as well as deaths, should guide programs • Available data on non-fatal cases are insufficiently complete and reliable • Improvement was foreshadowed in the National Road Safety Strategy Review and action plan • Linkage of crash data with health sector data has potential to provide better information • Consistent approach and cross-border flows

Aim Provide proof of concept for a national approach to obtaining routine national data on non-fatal hospitalised road injuries in Australia, using data linkage

Objectives 1. Learn whether relevant ethics committees and data custodians will allow the required use of data. Seek necessary approvals. 2. Test the technical feasibility of the method by applying it to one year of data. 3. Assess the utility of the linked data. 4. Communicate the results.

Data Sources • National Death Index • South Australia • Traffic Accident Reporting System • New South Wales • South Australia Inpatient Hospital • CrashLink Separations • NSW Admitted Patient Data Collection • Tasmania • Queensland • Crash Data Manager • Queensland Road Crash Database • Tasmanian Public Hospital Admitted • Queensland Hospital Admitted Patients Patient Data Collection Data Collection • Australian Capital Territory • Victoria • Territory and Municipal Services (TAMS) • Road Crash Information System crash database • Victorian Admitted Episodes Dataset • Admitted Patient Care Data • Western Australia • Northern Territory • Integrated Road Information System • Northern Territory Road Crash Data • Morbidity Data System • Northern Territory Inpatient Activity

Approach • Ethics committee and data custodian approvals are required in each jurisdiction, from the Australian Institute of Health and Welfare (for NDI data) and the participating universities. • The process being used is consistent with the separation principle that underpins the health data linkage framework in Australia.

Data linkage National Death Index Hospital Crash data data AIHW custodian custodian data linkage Authorised researchers will access non-identifying data via the Secure Unified Data Environment (SURE) SURE Identifiers and Project ID Researchers Project ID and content data Project Linkage Key and Project ID

Approval progress Jurisdiction Ethics approval Hospital data custodian Crash data custodian approval approval ✔ ✔ ✔ New South Wales ✔ ✔ ✔ Queensland ✔ ✔ ✔ Australian Capital Territory ✔ ✔ ✔ Victoria ✔ ✔ ✔ South Australia ✔ ✘ ✔ Tasmania ✔ Northern Territory Western Australia + Flinders University and Queensland University of Technology ethics approval + AIHW ethics and custodian approval for NDI

Data flow update Jurisdiction Hospital data to Crash data to Hospital data to Crash data to AIHW AIHW SURE SURE ✔ ✔ ✔ ✔ New South Wales ✔ ✔ ✔ ✔ Queensland ✔ ✔ Australian Capital Territory ✔ ✔ Victoria ✔ South Australia ✔ Tasmania Northern Territory Western Australia + National Death Index in SURE

Findings so far • Learn whether relevant ethics committees and data custodians will allow the required use of data • Ethics committees ✔ • Data custodians ✔ • Approval is for a non-identifying model of linkage only • No identifying data is provided to the researchers • Ethics committees and hospital data custodians will not approve content data being provided with identifiers included • Approval & data supply process was slow (20 months) • Similar to the few comparable projects • Likely to be quicker if repeated for other data-years • Linkage process and supply SURE much faster

Linkage and analysis • Two rounds of linkage 1. NDI, Queensland crash and hospital, and NSW crash and hospital Linkage is completed and content data is in SURE for analysis 2. Data from the first round and any additional data sets that are provided to the AIHW data linkage unit by end of November • Final report due March 2018
