Overview

Qualitätsring Medizinische Software e.V. (QMS) is a German registered association (eingetragener Verein) founded in 1992 and headquartered in Kerpen, North Rhine-Westphalia. It serves as the industry association for companies that develop software solutions for outpatient medical care in Germany. QMS brings together solution providers and service providers in the healthcare sector, originally to enable exchange between practice software solutions and medical measuring devices, and today to standardize all data exchange processes across sectors — between records, service providers, networks, and management companies. The association's purpose is to develop, test, maintain, and promote standards for the interoperability of IT solutions in the healthcare system. Its work aims to increase the quality, efficiency, and safety of public healthcare and thereby reduce costs. QMS is best known for developing the Gerätedatenträger (GDT) standard, a protocol for integrating medical measuring devices into electronic patient records, and for maintaining the LDT (Labordatenträger) standard. It is also a co-founder of SCIPHOX. QMS provides its members with practice-tested interface specifications for their applications. In the case of the GDT record description, QMS e.V. offers a free test module for testing. The association also issues official statements to the German federal government, gematik, and the KBV (National Association of Statutory Health Insurance Physicians) before new laws, guidelines, and specifications for outpatient care are finalized. It operates a closed knowledge network and intranet for its members, facilitating experience exchange and networking among partners with complementary expertise. Membership is aimed at manufacturers of medical software, consultants, and service providers who want to establish themselves in the German outpatient medical care market. QMS supports them with information and know-how for establishing secure and future-proof e-health products, as well as assistance with regulatory processes, particularly around standardization. The association positions itself as a recognized body that bundles industry expertise and provides orientation where others see only complexity.

History

Over time, its scope expanded to address the standardization of all data exchange processes across sectors — between patient records, service providers, networks, and management companies. The association is headquartered in Kerpen, North Rhine-Westphalia. It developed the Gerätedatenträger (GDT) standard, a protocol for integrating medical measuring devices into electronic patient records, and maintains the LDT (Labordatenträger) standard for laboratory data. QMS is also a co-founder of SCIPHOX, an initiative for standardizing communication in healthcare. QMS provides its members with practice-tested interface specifications for their applications. For the GDT record description, it offers a free test module. The association issues official statements to the German federal government, gematik, and the KBV before new laws, guidelines, and specifications for outpatient care are finalized. It operates a closed knowledge network and intranet for members to exchange experiences and find partners with complementary expertise.
