VAHI is leading a new project to link data from clinical quality registries (CQRs) with administrative datasets held by the Department of Health and Human Services (DHHS). The CQR Linkage Project aims to enable better use of CQR and administrative data to monitor and drive improvements in the quality and safety of healthcare. Our vision for the project is for VAHI, Safer Care Victoria (SCV) and DHHS, as well as Victorian public health services, to receive better information to support the provision of better, safer care.

VAHI is working with the Centre for Victorian Data Linkage (CVDL) to progressively incorporate data from five clinical quality registries (CQRs) into the Victorian Linkage Map (VLM). The VLM combines patient identifiers from over 30 datasets to bring together multiple datasets using a linkage identifier. The datasets in the VLM include many administrative datasets held by DHHS such as hospital in-patient and emergency records.

The five CQRs involved in this project are the Australian and New Zealand Intensive Care Society (ANZICS) Adult Patient Database, the Victorian Cardiac Outcomes Registry (VCOR), the Australian Stroke Clinical Registry (AuSCR), the Australian and New Zealand Society of Cardiac and Thoracic Surgeons Database (ANZSCTS) and the Victorian State Trauma Registry (VSTR).

The first phase of the project includes a proof of concept exercise to produce a linked dataset using the ANZICS Adult Patient Database. VAHI is consulting ANZICS and the SCV Critical Care Clinical Network to develop new quality and safety measures using the linked data. One possible use of linked data would be to examine long-term patient survival (e.g. five-year survival) using linked data from the Victorian Death Index.
