Localisation of historic and current PACS data

Initially, the project commences with the requirement for QE Gateshead to meet its obligations as it withdraws from the National PACS programme (part of the National Programme for IT (NPfIT)), by taking control of all the PACS data currently residing in the LSP Central Data Store (CDS). After serving notice on its existing contract that ends in June 2014, QE Gateshead has a limited time to bring its centrally stored image data back under the Trust’s full control. Utilising traditional localisation methods of standard DICOM Query/Retrieve across N3, the Trust was working to an estimated 10-month timeframe to bring all of the data back from the CDS. However, by working with BridgeHead, the Trust is able to utilise the tape store from its HSM system (put in place as part of the originally specified PACS environment) that contains a copy of all of the Trust’s PACS data archived in the CDS. As a result, taking control of the image studies, by transferring them into the BridgeHead VNA, is estimated at a massively reduced 12 weeks. These timings also include the storing of the latest 12 months of PACS image data, currently stored in the local cache, into the BridgeHead VNA. Finally, the Trust intends to use the BridgeHead VNA as one of the target nodes for new imaging studies created by the go forward PACS. Ultimately, phase one of the project will result in QE Gateshead using BridgeHead’s VNA as its local storage and management repository for all of its historic and current PACS data.

Integrating a new PACS application with the VNA

One of the reasons QE Gateshead selected BridgeHead’s VNA was as a result of its true vendor neutrality – BridgeHead’s VNA has the ability to interface with any PACS applications, regardless of the provider, as well as being able to work with any chosen storage device, irrespective of media or brand. This was very important for QE Gateshead as they plan to replace their PACS application and wanted to avoid vendor lock-in. Consequently, QE Gateshead’s strategy was to ensure that their chosen VNA could be utilised as the target archive for both existing images from the Trust’s current PACS and those created by a new PACS in the future – essentially keeping all of their studies in one place. The implementation of BridgeHead’s VNA will proceed in advance of any PACS replacement to ensure that all archived studies are consolidated into a local, central store, completely under QE Gateshead’s control. This will pave the way for the implementation of the go forward PACS application, once selected.

The future – a VNA for all imaging disciplines and beyond

In the future, QE Gateshead intends that the scope of the BridgeHead VNA extends to become the Trust’s single, enterprise-wide archive for all clinical imaging. This would result in the VNA environment being open to data from other disciplines outside of radiology PACS, such as (but not limited to) endoscopy, medical photography and scanned documents.

Once the image data management strategy has been fully implemented, QE Gateshead will consider adding administrative data sources into the fold. BridgeHead’s VNA is a subset of its wider Healthcare Data Management (HDM) Solution, which has the capability of storing and protecting all healthcare data, both clinical and administrative. By simply adding BridgeHead Agents to the solution, as required, QE Gateshead will be able to extend the VNA environment to BridgeHead’s full solution, having the ability to archive and manage a greater variety and volume of hospital data. As a result, the system will offer a horizontal view of all data, enabling applications, such as its Medway EPR, to search for all data pertaining to a patient. By keeping clinical and administrative data in one place, and offering this back to the hospital’s EPR system, QE Gateshead will be ever closer to achieving their vision by providing a holistic view of a patient’s entire medical record.

Earlier this month BridgeHead was named EMEA’s leading independent VNA provider by IHS, the global source of information and analytics.
