The Centre for Health Record Linkage charges a fee for the
linkage of data. This fee is based on a number of factors,
- The number of individuals (record groups) in the study;
- The number of datasets from which information is requested;
- Whether the study involves linking a dataset that is not part
of the Master Linkage Key (MLK). These studies involve
additional cost due to the number of clerical reviews required to
check the linkage of the external dataset(s).
The cost of linkage varies for each project. As an example
however, the linkage and extraction of records from two MLK
datasets for 50,000 individuals would cost approximately $5,000 ex
GST. The fee for linkage of an external (i.e. non-MLK)
dataset of 10,000 records and subsequent extraction of linked data
from two MLK datasets would be approximately $7,000 ex GST.
In each example, the cost would increase with the addition of more
datasets and individuals. Quotes can be obtained by
contacting the CHeReL (firstname.lastname@example.org)
or forwarding an Application for Data to the CHeReL.
Organisations that regularly use linkage services may opt to
apply for membership of the CHeReL. Staff of member
organisations receive substantial discounts for linkage and
extraction of records within the MLK. This significantly
offsets the costs of linkage for projects using large volumes of
data. For membership options and conditions, please contact
