Context: Data users (i.e., researchers, innovators, regulation agencies and policy-makers) need high-quality data. In HealthData@EU, data holders are expected to make their datasets available for secondary use, providing a notion of their quality and utility and the maturity of their data quality procedures. In article 56 in the HealthData@EU proposed regulation, this notion would take the form of a label. Goal: Overall, QUANTUM aims at developing and implementing a label mechanism that could be ideally adopted in the future HealthData@EU. Methods: QUANTUM builds on 5 technical work packages (WP). WP1 conceptualises and provides technical specifications for a data quality, utility, and maturity label. WP2 designs and tests, at small-scale, the label. WP3 implements the labelling mechanism in a number of data holders. WP4 engages the data quality users’ community; and, WP5 outreaches other interested parties, including other initiatives building HealthData@EU. Expected results: a) A common concept of datasets Quality and Utility and Data holders’ Maturity; b) Technical specifications for the label (Deliverable D1.1. and D1.2); c) A conformance checking tool that yields the label (D2.1); d) An implementation report of the label mechanism (D3.1); e) Recommendations for a large-scale implementation of the QUANTUM label mechanism (D3.2); and, f) The QUANTUM Exchange Platform and Academy (D4.2 and D4.3) as instruments for capacity building. Consortium: For this purpose, 27 beneficiaries, 5 affiliated entities and 3 associated partners. The composition of the Consortium seeks to reflect the different roles and institutions in the governance of the HealthData@EU; virtually consider all types of data and science of interest; and gather the expertise of previous outstanding projects in the domain

XpanDH is a CSA aimed at mobilizing and building capacity in individuals and organisations to create, adapt and explore purposeful use of interoperable digital health solutions based on a shared adoption of the European Electronic Health Records Exchange format (EEHRxF) across Europe. This pan-European effort will use a “network-of-networks” approach ensuring that digital health actors are motivated and supported by tailored guidance and real examples to help early adopters to advance to the concrete use of EEHRxF-embedded digital health solutions to add value to health and care and promote Personal and European Health Data Spaces. XpanDH pursues the main goal of maturing and accelerating a sustainable and scalable interoperability environment for digital health innovations based on the EEHRxF, around 5 Goals: 1) To develop robust technical specifications and resources for the EEHRxF building; 2) To establish the X-Bundle Readiness model; 3) To verify the usefulness of the X-Bundle in real-world with a set of early adopters grouped under selected adoption domains; 4) To mature a pan-European digital health ecosystem of solution providers and end-users, 5) To develop a framework for sustainable ecosystem. The consortium will thrive on past and ongoing eHealth interoperability projects and services, and particularly on the X-eHealth and DigitalHealthEurope projects recommendations, through digital health data activism and strong patient engagement. It brings together 26 Digital Health Actors under a co-creation and co-implementation concept, supported by a Policy Board (linking to Governments and the eHealth Network). To expand its impact, 10 XpandDH networks of hundreds of health stakeholders will be nurtured to form a vibrant pan-European (Digital) Health space converging on common, usable, and reliable tools for real interoperable services that adoption of the EEHRxF and enhance healthcare cooperation for better health towards a European Health Union.
