Lumos: a statewide linkage programme in Australia integrating general practice data to guide system redesign

Area of Science:

• Health Informatics
• Data Linkage
• Population Health

Background:

• Australia's aging population necessitates integrated healthcare services across various settings.
• Siloed health data in Australia hinders comprehensive patient journey analysis.
• The Lumos programme addresses this by establishing a statewide linked data asset.

Purpose of the Study:

• To describe the establishment of the Lumos programme, Australia's first statewide linked data asset.
• To evaluate the representativeness of the Lumos data asset compared to the census population.
• To assess the utility of linked data for understanding healthcare utilization.

Main Methods:

• Linking general practice records from New South Wales (NSW) with acute and other health system data.
• Utilizing innovative privacy and security technologies for data updates.
• Comparing demographic distributions of the Lumos cohort with the NSW census population using multiple representation measures.

Main Results:

• The initial Lumos data extraction linked 1.3 million general practice patients, representing 16% of the NSW population.
• The demographic distribution of the Lumos cohort showed >95% alignment with the NSW population.
• The data asset provides a representative view of general practice patients in NSW.

Conclusions:

• The Lumos programme provides an updated data resource for insights into statewide, cross-setting healthcare utilization.
• The Lumos data asset is representative of the overall NSW population.
• Lumos data can reliably inform health service planning, design, and impact monitoring in NSW.
