GDSN – What You Need To Know

What is the GDSN?

The Global Data Synchronization Network (GDSN) is an internet-based, interconnected network of interoperable data pools and a global registry known as the GS1 Global Registry. It enables companies around the globe to exchange standardised and synchronised supply chain data with their trading partners.

Why do suppliers need to join a GDSN-Certified Data Pool?

As part of the NHS eProcurement Strategy, the UK Department of Health is mandating that suppliers of Medical Devices to the NHS must adopt GS1 standards, and join a GDSN-Certified Data Pool to publish their product data, if they wish to continue to sell into the NHS.

Do hospitals need to join a GDSN-Certified Data Pool to retrieve supplier product data?

No. The Department of Health is looking to provide a centralised NHS Master Data Exchange Service, to which suppliers will send their product data using the GDSN. From there, catalogue service providers, like GHX with NEXUS, would retrieve the product data for visibility to their connected hospital community, negating the need for hospitals to join a GDSN-Certified data pool. In the meantime, with the absence of this centralised data service, GHX can still support delivery of GDSN product data to its hospital community.

Do hospitals need a catalogue management solution?

Yes. Data syndicated through the GDSN is difficult to consume directly into the hospital’s point-of-use systems. Catalogue Management Solutions allow hospitals to easily consume and manage product data for usage in their requisitioning, inventory management and other systems.

How do suppliers provide pricing data to the hospitals?

It is recognised that the GDSN, at this point, is not matured enough to adopt for delivery of pricing. Therefore, the Department of Health is asking that suppliers send pricing data using the GS1 XML Price Sync file format directly to the hospitals, and using a method of their choosing.

Can GHX support suppliers and hospitals with becoming compliant?


Suppliers of Class III and IVD list A medical devices must join a GDSN-Certified data pool and publish their product data through it by the 30th of September 2017. We can support suppliers to become compliant with this, through use of our catalogue management and GDSN-Certified data pool solutions – HealthNEXUS with Health ConneXion.

We also support hospitals in becoming compliant using our catalogue management solution – NEXUS, so they can easily consume and manage data syndicated through the GDSN for usage in their systems.



Why use GHX?

We know healthcare and have the only healthcare focused GDSN-Certified data pool, Health ConneXion. Our catalogue management solutions process more than 800 supplier catalogues, and are being used by over 70 NHS Trusts, including four of the six Scan4Safety demonstrator sites.
