In the Data Services Branch (DSB), many factors impact on how long it takes to process a research application and complete the requested data linkage such as:

• The application is incomplete and/or does not provide an accurate description of the data required;
• The number of datasets involved in the linkage and if they are present in the Master Linkage File;
• The number of other linkage requests that require the attention of the DSB Linkage Team;
• The data quality of external datasets and how long it takes for them to be provided to DSB for linkage.

For a more detailed explanation see Factors Associated with Time Taken to Complete a Linkage Request.  If you would like more information about research requests or a proforma for applications under the Public Health Act 2005 (PHA), see How to access data from the Data Services Branch for your research project.

Example timeframes

The following timeframes are examples of previous research requests that were submitted to the DSB and involved data linkage. These examples illustrate the application and linkage process, and the factors that may impact on the time frame.  Each request is unique.  The following are examples only.

Example 1.  A PHA application involving one dataset sourced from DSB.  This example represents a relatively simple linkage request and approval process.
Example 2.  A PHA application with three datasets accessed from the DSB Master Linkage File and one dataset external to Queensland Health
Example 3.  A PHA application with three datasets accessed from the DSB Master Linkage File and five external datasets
Example 4.  A consent request with two datasets accessed from the DSB Master Linkage File and five external datasets
