Us and them: data linkage from the perspective of custodians and users Angela Watson, Kirsten McKenzie, and Barry Watson International Data Linkage Conference, Perth May 2-4, 2012 CRICOS No. 00213J
Road safety A reliance on police data • Good information about crash circumstances • Under-reporting • Injury outcomes • Cost and prioritisation • The new Australian National Road Safety Strategy 2011-20203
Road safetyOther data sources • Patients admitted to hospital • Emergency department • Ambulance Service • Coroner’s • Increasing interest in data linkage

What needs to be done first? • Data quality • “garbage in garbage out” • Accessibility • Feasibility • Which model is most worthwhile?
Current study • Interviews with custodians, users, & linkage experts • Data quality • Accessibility • Data linkage
What is data linkage? Extent of data sharing Identifiers All data elements Frequency Ad-hoc Routine CODES (US) WA QLD WA WA/QLD
Benefits of linkage Road safety • Validation tool
People seem to see the benefit, so why has it still not happened?
Summary • Accessibility problems may be more than just about privacy • Relationships important • Different views on linkage • Extent of sharing • Frequency
Summary • Benefits • Validation tool • Adding information • Barriers varied depending on model • What next.........
