Medicines 
Counterfeit medicines have become a growing global threat over the last few decades and with more and more regulatory authorities in countries such as Argentina, Brazil, India, South Korea, Saudi Arabia, Turkey and the EU, adopting or undergoing procedures to adopt requirements for the use of counterfeit medicines. global, unique drug identifiers, as well as serialization to protect the supply chain.
As of 09 February 2019, the European Medicines Traceability System established by Delegated Regulation (EU) 2016/161 of 2 October 2015 supplementing Directive 2001/83 / EC on counterfeit medicines is already successfully operating in the European Union.
One of the main objectives of the European Directive is to prevent entry into the legal supply chain of counterfeit medicinal products and to guarantee the integrity of the product and the authenticity of the medicinal products (safety and product serialization indicators).
Detailed rules for the safety features on the packaging of medicinal products for human use are laid down. One of the indicators is the mandatory printing of the GS1 GTIN, a global business unit number in a 2D Data Matrix barcode.
Мedical devices 
Unique Device Identification (UDI) is a system used to label and identify medical devices within the healthcare supply chain.
The EU Medical Device Regulation EU MDR 2017/745 and the EU In vitro Diagnostic Device Regulation (EU IVDR 2017/746) set legal requirements for a Unique Identification of Medical Device (UDI) system in Europe. One of the issuing agencies of the Unique Device Identification UDI number was chosen to be GS1, with GTIN the global trade item number, at the base of the unique product identifier.
According to the regulations, the UDI number must be affixed to the label of the medical device, its packaging and in some cases the device itself.
The regulations also provide for the creation of a European database EUDAMED (European). EUDAMED’s entry into service date is March 26, 2020. From May 26, 2020 for medical devices and from May 26, 2022 for in vitro diagnostic devices, it will be mandatory to enter data on EUDAMED-related products. In order to enter data, a basic Basic UDI-DI identification number of the medical device group to which the device belongs is required.
GS1 has developed a new standard to support the implementation of Basic UDI-DI: Global Model Number (GMN). The latest version of GMN is available online at https://www.gs1.org/docs/barcodes/GSCN_19-012_GlobalModelNumberUpdate_v3.pdf
You can use the GS1 calculator to calculate the GMN check characters or confirm your
GMN (Basic UDI-DI)
The necessary product data must be provided to EUDAMED, the EU regulatory database for regulated medical devices. https://ec.europa.eu/growth/sectors/medical-devices/new-regulations/eudamed_en
Best practices 
While the aging population is increasing globally and treatment is becoming more and more modern, healthcare as a primary overall objective requires the provision of the best possible care for patients at all times.
Over the last 10 years, the implementation of GS1 standards has led to an increase in healthcare efficiency, and now the focus is on expanding the use of these global standards in conjunction with healthcare providers.
Global good practices show the many benefits of implementing GS1 global standards in processes covering patient health care, traceability, automation, regulatory and more.
Look for among the hundreds of completed applications this practice that would encourage you and your company to lay the foundations for.
Data Exchange/Traceability 
GDSN – Global Data Sincronization Network in healthcare
Data synchronization enables healthcare trading partners to share reliable product data, locally and globally, in an automatic and effective manner. This allows to reduce errors and increase efficiency. Inconsistent, inaccurate and outdated product information, for example, makes it almost impossible for hospitals to make effective deliveries down the supply chain. This would affect all other processes and systems in the hospital that require accurate product information and ultimately affect patient safety.
The introduction of the GS1 Global Data Synchronization Network (GDSN®) continues to grow globally in healthcare. GS1 Member States (MOs) work closely with their local health communities to enhance the value of reliable data and the role that GDSN plays in the exchange of accurate, reliable, complete and timely information on medical devices and pharmaceuticals.
GS1 EDI in healthcare
GS1 EDI provides global standards for electronic business communications that enable fast, efficient and accurate automatic electronic transmission of agreed business data between trading partners. Standards are used worldwide in more than 15 sectors.
In the healthcare sector, GS1 EDI is widely used by manufacturers, hospitals, pharmacies, GPOs and logistics service providers.
The Healthcare EDI Implementation Kit will provide GS1 members and healthcare industry stakeholders with the tools to implement the GS1 EDI standards.

GS1 and EPCIS taceability standard
What is traceability?
Traceability in healthcare allows the visibility of the movement of prescribed drugs or medical devices in the supply chain – traceability back to the time of production and forward along the intended route of the product to the point of healthcare.
Traceability of healthcare products eliminates counterfeit healthcare products, increases patient safety, and complies with regulatory requirements.
The Global Health Traceability Standard (GTSH) provides a foundational framework that describes the tracking process and sets minimum requirements for all stakeholders, regardless of technology, organization size or operational complexity.
EPCIS is a GS1 standard that allows trading partners to share information about the movement and location of products and assets in the supply chain based on four types of events:
WHAT – what product (including sales unit, pallets, packaging, etc.) identified by GS1 keys (GTIN, GTIN + batch number, GTIN + serial number, SSCC, GRAI, etc.)
WHEN – an event occurs related to the identified product – date, time, etc.
WHERE – was the product and where is it now – location, via GLN number
WHY – the relevant event happens – send, receive, in transit, downloaded, etc.
