Aims
To describe the process of the VICS transitioning to a secure, cloud-based environment for accessing administrative cancer data via virtual machines (VMs).
Background
The Centre for Victorian Data Linkage (CVDL) require improved and simplified access to, improved accuracy of, and better secured sensitive patient administrative health data for the VICS. The VICS are Victoria’s only dedicated cancer improvement network. Previously this data was available via a protected CSV file which was downloaded by each VICS for local data storage and analysis to facilitate cancer services improvement.
Methods
CVDL developed the Victorian data Access Linkage Trust (VALT) for the release and analysis of linked data. Data is accessed within the secure cloud environment of the VALT with analysis undertaken via Virtual Machines (VMs). Each VICS have their own VM in the VALT.
Results
Data access through the VALT allows high compliance with privacy legislation and information management standards than has previously been possible, as well as reduction of the security, privacy, and storage burden. It allows approved access to further health administrative datasets, and centralising tools and processes to reduce duplication of effort, enhancing collaboration between the VICS.
The transition into the VALT involved the development of business requirements, technical specifications, and a service protocol to ensure roles and responsibilities for the VICS and CVDL are specified.
A new, centralised database schema and data transformation process for the VICS, and associated training materials to support the move were developed.
Conclusions
The transition into the VALT has proven to be a significant technical and change management process. However ultimately the benefits of improved data governance, security and consistency across the VICS will be a significant success.
