Data Linkage Costs

The Centre for Health Record Linkage (CHeReL) charges a fee for the linkage of records undertaken by CHeReL. The fee matrix below shows the estimated fees for CHeReL linkage services, depending on the cohort size and the number and types of datasets to be linked.

For example, a research project with a cohort of up to 5,000 persons, using up to 10 datasets which includes a combination of 5 MLK and 5 external (non-MLK) datasets, will cost approximately $12,000, excluding GST, for the linkage service.

The following details what is included and excluded in calculating the estimated fee for the linkage service:

The price estimate is exclusive of GST, which is payable on top of the estimated amount above.
Estimates assume clean data is provided, i.e. identifiers are available and content is linkable. Should a data cleaning service be required, additional fees will apply.
Estimates assume that each non-MLK dataset to be linked comes in one file. Additional data sourcing fees applies for more than one file per dataset.
Additional linkage fees (starting from $5,000) apply for the following types of linkage services: case-control (eg requiring control selection), family (eg linkage of mother and child records), cross-agency linkages (e.g. ABS and AIHW) and cross-jurisdictional linkages (eg NSW and Victoria).
Additional fees may apply for projects requiring more intensive project management, or where data extraction is required.
A more detailed quote will be provided after your full application has been submitted to the CHeReL.

Please note, the 45 and Up Study may charge a fee for data extraction which is not included in the linkage fee. For more information, please contact the 45 and Up Study at 45andup.research@saxinstitute.org.au.
