Towards a European health research and innovation cloud (HRIC)

Abstract

The European Union (EU) initiative on the Digital Transformation of Health and Care (Digicare) aims to provide the conditions necessary for building a secure, flexible, and decentralized digital health infrastructure. Creating a European Health Research and Innovation Cloud (HRIC) within this environment should enable data sharing and analysis for health research across the EU, in compliance with data protection legislation while preserving the full trust of the participants. Such a HRIC should learn from and build on existing data infrastructures, integrate best practices, and focus on the concrete needs of the community in terms of technologies, governance, management, regulation, and ethics requirements. Here, we describe the vision and expected benefits of digital data sharing in health research activities and present a roadmap that fosters the opportunities while answering the challenges of implementing a HRIC. For this, we put forward five specific recommendations and action points to ensure that a European HRIC: i) is built on established standards and guidelines, providing cloud technologies through an open and decentralized infrastructure; ii) is developed and certified to the highest standards of interoperability and data security that can be trusted by all stakeholders; iii) is supported by a robust ethical and legal framework that is compliant with the EU General Data Protection Regulation (GDPR); iv) establishes a proper environment for the training of new generations of data and medical scientists; and v) stimulates research and innovation in transnational collaborations through public and private initiatives and partnerships funded by the EU through Horizon 2020 and Horizon Europe.

Background

Genomics has brought life sciences into the realm of data sciences—large-scale DNA and RNA sequencing is now routine in life-science and biomedical research, with an estimate of up to 60 million human genomes available in the coming years [1, 2]. Recent innovations in medical research and healthcare, such as high-throughput genome sequencing, transcriptomics, proteomics, metabolomics, single-cell omics techniques, high-resolution imaging, electronic health and medical records (EHRs/EMRs), big-data analytics, and a plethora of internet-connected health devices, fundamentally change the infrastructure requirements for health research.

Translating these new data together with clinical information into scientific insights and actionable outcomes for improving clinical care is a major challenge. As life-science and health research datasets rapidly grow larger, with an ever-increasing number of study participants required to detect meaningful but weak signals that may be blurred by a myriad of confounding biological, experimental, or environmental factors, the computational resources required to process and analyze this big data increasingly outgrows the capabilities of even large research institutes. The various cloud technologies and services defined in Table 1 are based on shared commercial and private computer and storage resources that can be provided on demand to users from a large number of different institutions who are conducting or participating in joint projects. They have emerged as powerful solutions to the challenges of collaborating in research on genomic, biomedical, and health data.

Table 1 Glossary of cloud computing terms

Biomedical and health research has yet to enter fully the big data and cloud computing era. The Health Research and Innovation Cloud (HRIC), as described in this manuscript, would help to facilitate this transition, providing access to larger datasets, cutting-edge tools, and knowledge, as envisioned by Auffray et al. [3]. For example, the HRIC should ease the incorporation of domain expert knowledge into systems disease maps in a format that can be both understood by all stakeholders (patients and clinicians, scientists, and drug developers) and processed by high-performance computers, thus supporting the development of innovative medicines and diagnostics [4, 5]. Cloud technologies (accessed through Hadoop applications, for example) also make it possible to collaborate and to access and reuse data in situations when privacy concerns or regulation prohibits remote users from downloading data—an important benefit in Europe where national regulations can differ significantly. Clouds allow algorithms to be brought to the data, and as such can enable data sharing and joint processing without generating unnecessary copies of the data, which comes with potential benefits for data protection [6, 7]. In addition, clouds make it possible to perform computational analyses at a scale that individual institutions would struggle to manage [7]. Consequently, in the past few years, the large international cancer and other genomics consortia have created specialized genomics and biomedical cloud environments, each supporting individual projects [2]. These projects have made important advances in connecting health research data across disciplines, organizations, and national boundaries. For instance, in research on rare diseases, international collaborations that integrate genomic, phenotypic, and clinical data have introduced new paradigms in diagnosis and care [8]. However, a project-based, fragmented landscape will not enable access to and construction of the large data cohorts that are required to address novel or broader biomedical questions that were not anticipated when collecting informed consent from participants in individual projects, nor will it provide adequate data governance and containable cost models.

Scaling and sustainably managing such solutions to support all European life scientists thus require a coordinated action from science policy makers, funders, and other actors in this complex ecosystem. Connecting Europe’s health data to advance the understanding of life and disease requires that research data and analysis tools, standards, and computational services are made FAIR—that is, findable, accessible, interoperable, and reusable—for researchers across scientific disciplines and national boundaries [9]. Truly enabling personalized and digital medicine across Europe and beyond will require a connected digital infrastructure for Europe’s health data that supports systematic openness and the integration of research data with real-world datasets (e.g., environmental monitoring data) generated inside all of the healthcare systems, government agencies, foundations, and private organizations that will adopt it.

On 13 March 2018, the Health directorate of the Directorate-General for Research and Innovation of the European Commission of the EU organized a workshop to explore the possibility of and challenges involved in establishing a cloud for health research and innovation, which would be accessible by researchers and health professionals throughout Europe, in line with recommendations for a European Innovation Council and the Horizon Europe 2021–2027 framework program [10, 11]. The cloud-computing environment proposed in this manuscript builds upon the European Open Science Cloud (EOSC) initiative developed in the past few years by the European Commission [12], with a focus in the life science and medicine fields. The EOSC aims at developing a trusted, open environment in which the scientific community can store, share, and re-use scientific data and results. Overall, the authors feel that the cloud described in this manuscript, which would provide the biomedical and health research community with the technical infrastructure and services necessary to support the development of innovative diagnostics methods and medical treatments, should become an integral part of the EOSC. The workshop gathered a broad range of experts from multiple biomedical research disciplines, health care, informatics, ethics, and legislation, including representatives of more than 45 collaborative projects funded by the EU through the FP7 (The European Union’s seventh framework programme for Research, Technological Development and Demonstration) and Horizon 2020 (H2020) programs. The participants explored requirements and developed a set of recommendations for a European HRIC to connect researchers and health data sources in Europe [13]. The main aim of the HRIC is for clinical data, software, computational resources, methods, clinical protocols, and publications to be more widely and securely accessed and reused following the FAIR principles [9] than is currently possible with existing European research infrastructures, such as ELIXIR, that form a network of heterogeneous national nodes. For example, the HRIC infrastructure would benefit from the aforementioned advantages of cloud computing in the archiving and dissemination of health data.

This paper summarizes the main conclusions from the workshop and highlights five recommendations and action points to the EU and national stakeholders (Table 2). The recommendations are key issues that need to be addressed in order to link biological, clinical, environmental, and lifestyle information (from single individuals to large cohorts) to the health and wellbeing status of patients and citizens over time, while making this wealth of data and information available for European health research and innovation in clinical care.

Table 2 Summary of the recommendations, details on the rationale, and suggestions for action points directed to the funding agencies and the actors in the field

The HRIC should be built on established standards and guidelines, to foster European-wide medical research

Rationale

Sharing of data, information, and knowledge represents the most important functionality in the context of a HRIC. High-level standardization, common exchange mechanisms, interfaces and protocols, and semantic interoperability form the foundation for widespread adoption of the FAIR principles [9] in health research. Data that are shared collaboratively in such health-related cloud projects are now largely standardized for the processing of genomic DNA read and genomic variant-calling files. By comparison, the sharing of highly sensitive clinical and health data has been much less developed to date and hence represents a key area for future focus. Numerous challenges remain with regard to sharing these data in a meaningful way.

Existing standards and guidelines

Many individual projects, in Europe and globally, have demonstrated the opportunities and the added value presented by connecting and exchanging data across countries via standardized protocols. Table 3 lists recent European projects that have developed towards the exchange of clinical and health data using cloud-based solutions. All of those projects have developed and implemented worthy ideas that should be included in the HRIC. However, we envision the HRIC as a disease-agnostic environment, and on a larger scale than the platforms mentioned in Table 3. Moreover, the HRIC should not be tied to a single project or consortium, but should rather be under the governance of an independent body. International exchange of health research data holds tremendous potential in disease research by facilitating better investigation of disease causality and linking of genotypes and phenotypes, as has been demonstrated, for example, in the Pan-Cancer Analysis of Whole Genomes (PCAWG) project. An important aspect of cloud-based data governance is that it allows sharing of data outside a consortium through a data request mechanism and a governance infrastructure that track participant consent and data access. The cloud-based audit trail capabilities of cloud-based research analyses, which can be implemented at both data and infrastructure levels, is a direct benefit to the data controllers. A standardized data model (or data access model) and/or standardized metadata models facilitate the consolidation of different data sets and significantly increase the findability, the semantic interoperability, and, as a consequence, the reusability of data, and thus its ‘FAIRness’ [9, 14].

Table 3 Relevant initiatives for the European Health Research and Innovation Cloud (HRIC)

Workshop participants agreed that a first minimalistic and yet effective approach to data exchange should consist of a small number of initial online repositories containing references (e.g., links to render data sets findable) along with metadata (e.g., type and scale of content, specifications describing in what systems the data set may be stored and processed), and indications on how to gain access (e.g., requirements and point of contact). This could be designed as a metadata repository containing the metadata of data objects and information on how to gain access to them. The data objects as such may, or indeed should, be stored elsewhere.

Beyond their metadata, however, data sets are bound to differ greatly because research projects vary largely in scope. Not only would it be cumbersome to record a large number of parameters that are irrelevant to the specific question addressed, but it would also be problematic from an ethics viewpoint, considering patient personal data protection aspects [15]. It therefore seems more promising to drive standardization within research communities while looking out for opportunities for overall standardization.

Thus, the workshop envisioned the HRIC as a distributed collection of data repositories, people, and services, which together make up a framework for sharing and operating as a federated data commons, with reproducible software, standards, and expertise based on joint policies and guidelines on conducting health research, much like the smaller frameworks used successfully in previous initiatives [2, 16,17,18,19]. The need for federation is also highlighted in the proposed EU action plan for ‘Making sense of big data in health research’ [3]. Creating such a HRIC opens new frontiers for research and healthcare via the opportunities for strong international collaborations.

Beyond Europe, the HRIC should collaborate internationally to drive the development and widespread adoption of global standards and connectivity. Ongoing initiatives exist outside Europe that are aiming to develop global standards for the secure exchange of data sets such as health and medical records within health information federations, while tracking the completeness of the supporting data [20, 21]. These initiatives also aim to develop guidelines for data analytics and standardized workflows. They should be considered for the basis of the HRIC as this will provide the scientific community with means of reproducibility, version control, and documentation, which will be an important vehicle to drive increased standardization and connectivity.

A European HRIC should be developed and certified to the highest standards of interoperability and data security

Rationale

The workshop participants enthusiastically endorsed the vision of the HRIC as a federated environment. The major blockers for cross-border collaborations in translational research on disease prevention, treatment, and management will be addressed through a federated HRIC infrastructure with work on the standardization, harmonization, and integration of genomic data with other health-relevant information to optimize hypothesis-driven analyses. The data sources will remain at their location of origin and are made accessible to users through a metadata repository. Moreover, data security has to be integral to the development of the HRIC, and modern cryptology and access control techniques will be used to ensure the protection of the patients’ data contained therein.

Standards in interoperability and data security

European health systems have different ways of managing and storing health data, making the exchange of clinical data between the EU member states complex. The challenges are well illustrated by EHRs and their use as secondary research material. In a recent Organisation of Economic Collaboration and Development (OECD) report [22], ten countries reported comprehensive record sharing within one country-wide system designed to support each patient having only one EHR (Additional file 1). These countries are Estonia, Finland, France, Greece, Ireland, Latvia, Luxembourg, Poland, Slovakia, and the United Kingdom (England, Northern Ireland, Scotland, and Wales). In these countries, plans call for patient records regarding patient treatment, current medications, and laboratory tests and medical images to be shared among physician offices and between physicians and hospitals. Some have already implemented part or all these functionalities, while others are progressing toward it. In other countries, key aspects of record sharing are managed at sub-national level only, such as within provinces, states, regions, or networks of health care organizations (for example, Austria, Germany, Italy, Netherlands, Sweden, and Spain; Additional file 1). Among these countries, all have implemented or are planning the implementation of a national information exchange that enables key elements to be shared country-wide. On the basis of the recent reports of the European Commission [23], Belgium, Malta, Portugal, Romania, and Slovenia are now developing national EHR systems, leading to a total of 16 EU member states that will provide such services.

Within the framework of the Joint Action on Rare Cancers, an EU initiative that brings together European research centers, policy makers, and other stakeholders with the aim of setting the agenda at national level, an analysis was made on the status of eHealth medical records in the EU member states. This work builds on the OECD study and complements this with information provided by the European Commission on the national laws on EHRs in the EU member states [24]. Thus, all EU countries are investing in the development of clinical EHRs, but only some countries are moving forward the possibility of data extraction for research, the provision of statistics, and the enablement of other uses that serve the public interest (P. Bogaert, personal communication). Countries that develop EHR systems that combine or virtually link data together to capture patient health care histories can potentially use these for long-term follow-up of cancer patients. Figure 1 shows how data from various sources can be integrated to provide a full picture of patients’ health status over time and to carry out research on patterns and anomalies in large populations using the specific combinations of data and analysis resources relevant for each research project, while ensuring compliance with security and data protection regulations.

Proposed general architecture of the HRIC European (inter) national databases, with varying data formats and data types referenced in a metadata repository, following formatting rules of the federated data commons as agreed at the HRIC governance level. The different users, after access control to the cloud, use the HRIC interface to access the repository, which gathers the relevant data and performs analysis, with outputs such as mathematical models, data visualizations, statistics, and patient’s profiles according to the users’ needs

The H2020-funded project EOSC-Life [25] is developing policies, specifications, and tools for the management of data for biological and medical research, including aspects of eHealth data. The use of common metadata standards, developed in EOSC-Life, as a foundation for remote data discovery and access was emphasized by the workshop participants as a key enabler for the HRIC. For instance, practical and legal considerations for cloud computing of patient data, which include the responsible use of federated and hybrid clouds set up between academic and industrial partners, have been put forward by early EOSC pilot projects [26].

The workshop participants emphasized that sustainability aspects are critical and must be considered from the start. To ensure that a HRIC could respond properly to emerging needs, innovation, and technology changes, a distributed federated storage solution offering access to FAIR data and services should be built according to modularity principles. In particular, owing to the long-term nature of a HRIC, due consideration should be given to deploying generic and modular computational methods and/or data storage management systems, while the information and communications technology (ICT) infrastructure should be flexible, portable, and expandable.

The million European genomes initiative [27] is a case in point: 18 member states have already signed the Genomics Declaration of Cooperation [28] to enable cross-border access to genomic databases and other health information. This federation of national initiatives [28] will provide secure access to such data resources in the member states to enable the discovery of personalized therapies and diagnostics for the benefit of patients. The initiative involves aligning strategies of ongoing national genomic sequencing campaigns with complementary de novo genome sequencing to obtain a total cohort of one million Europeans, accessible in a transnational framework, by 2022 [29]. The HRIC would form a basis for such large-scale, permanent collaborations.

The workshop participants recognize that ensuring maximal data security is paramount in building and maintaining trust with European citizens. To address this issue, we suggest using modern cryptology such as blockchain to ensure data security by design, and holding regular data security assessments (for example, using hackathons and/or commercial security audits). As shown in recent literature, the use of blockchain in biomedical research is still in its infancy [30]. However, blockchain or other advanced cryptology tools that can be used to protect data in a cloud environment could prove useful in ensuring the secure and trustworthy implementation of the HRIC [31].

The HRIC must be supported by a robust ethics and legal framework that is compliant with the general data protection regulation

Rationale

Compliance with General Data Protection Regulation (GDPR) and other data protection laws, as well as enforcing an ethical usage of data, is paramount to gain the general public’s support and trust in the HRIC.

Existing ethics and legal framework

Unblocking the legal and administrative barriers for sharing human research data across geographical and organizational boundaries will, if the trust of research participants is preserved, pave the way for continent-scale cohorts in life-science research. This will represent a significant innovation as the sharing and joint analysis of sensitive data has until now been severely limited because of the different restrictions inherent to the different classes of sensitive data. By using a federated database model, with a metadata repository within the HRIC cloud encrypted environment, data security is maintained while innovative data analyses can be performed by bringing the algorithms to the data rather than centralizing the data [32]. Federation, rather than full integration of all available resources, poses an important challenge for the implementation and deployment of an effective HRIC. The set-up and functioning of a HRIC requires a robust foundation of legal agreements and ethics rules and procedures, as well as security and data protection compliance protocols. Importantly, these elements must be introduced during the conception and design phase as part of HRIC governance. Indeed, in order to enable different HRIC actors to provide access to their data sources, manage these resources within the cloud, and access these resources, it is essential to incorporate policy requirements into the design of the HRIC itself and to manage the complexity involved by implementing simple and intuitive user interfaces and project portals. This may be challenging considering the heterogeneity of health systems and health market access across Europe and will need the sharing of a common agreed vision across EU member states.

Ethical, societal, and privacy considerations for (re) using health-related data have been outlined in the Code of Practice on Secondary Use of Medical Research Data, which was developed in the European Translational Information and Knowledge Management Services (eTRIKS) project funded by the Innovative Medicines Initiative (IMI) [33]. In addition to clear and explicit consent, explicit dissent may need to be considered for the use/re-use of data. Ultimately, each citizen and patient must be able to access her/his own data and know when and where it has been used and for what purpose. In addition, the difficult question of the business model of using those data should be discussed at various levels from ethics, social, and economics standpoints, taking into account the potential future development of products and services using personal medical data. Furthermore, the goal of providing citizens with personalized services requires technical advancements in the collection and analysis of data (for example, in data analytics and machine learning). For this type of usage, simple consent mechanisms might not be sufficient. For example, how should a clear data-collection purpose statement be defined if data are collected for multiple usage scenarios across a distributed/federated cloud, in which actors from different geographical and legislative environments will need to interact and cooperate? Would an excessive number of consent requests minimize data provision for research or clinical applications? Another level of complexity is introduced by the heterogeneity of data protection and privacy regulations when the data originate from states with federated national health systems (e.g., Germany and Italy). Development of large-scale European access mechanisms will require open consultation and engagement with national policymakers, patient organizations, and wider society to build the trust and confidence needed for widespread adoption and sustainable operations.

In addition to technical, ethical, and legal specifications, a global integrated governance model needs to be established for the HRIC that is in line with that of the EOSC, regulating the roles and responsibilities of all contributing institutions and users, and procedures for authentication and access control to individual resources. Principles, with specific guidelines on implementation in a HRIC environment, will need to be developed in order to manage and regulate aspects such as ownership, access, transparency, sharing, integration, standardization of data and metadata formats, tools, and frameworks, while ensuring confidentiality and sustainability. All of these principles need to be developed with the overarching objective of providing benefit to and preserving the trust of patients and the general public.

Health data mostly represent sensitive data, which need to be managed to preserve the trust of patients, research participants, and the general public, respect social norms, and naturally comply with the rules and regulations of data protection laws, notably the EU GDPR [15]. Although the GDPR directly applies across the EU and its provisions prevail over national laws, EU member states retain the ability to introduce their own national legislation under certain derogations provided for by the GDPR itself. The GDPR also introduces the notions of ‘Privacy by Design’, which means that any organization that processes personal data must ensure that privacy is built into a system during the whole life cycle of the system or process; and ‘Privacy by Default’, which means that the strictest privacy settings should apply by default, without any manual input from the end user. In addition, any personal data provided by the user to enable the optimal use of a given health dataset should only be kept for the amount of time necessary to provide the intended product or service [15].

Thus, successfully linking and accessing biomedical and health data across Europe will require many different disciplines and specialists working together, with a coordinated effort that should encompass controlled access mechanisms to ensure compliance with privacy and data protection regulations. Data providers need logging and monitoring functionalities to comply with the GDPR and to enable tracking of data and methods within the system, controlling instances and routines that check for the adherence to predefined standards and formats to guarantee data integrity. Access mechanisms need to be developed that support the researchers, data producers, and data analysts to request permissions and fulfill the reporting requirements for data use in national and international research projects; this is a significant regulatory, political, and sustainability challenge [34]. Such mechanisms include, in particular, considerations about the rights of patient donors and research participants, taking into account the data protection aspects of various legal systems and local regulations. Researchers have to face differences in the understanding of the right to data protection in those different regional or national European ecosystems.

There is an urgent need for standardized, usable, data-protection-policy-compliant solutions for sensitive data sharing which are capable of integrating and analyzing health data from different sources, organizations, and potentially from different research disciplines. These aspects are subject to ongoing discussions and debates in the EOSC initiative [35]; for instance, progress has been made in the Human Brain Project (HBP) through its Ethics and Society sub-project in collaboration with the project platforms [36, 37]. Other examples of data sharing that are compliant with data protection policies can be found in the recent literature [38,39,40,41,42,43,44,45]. Furthermore, there is the issue of capacity, with the amount of data starting to strain the infrastructure of any individual hospital or research institute. Thus, the interplay between privacy, data security, and access control on one hand and access (including cost-recovery models) to storage, computational, and analysis resources on the other hand will be a defining element of the policy and technology development of a decentralized digital health infrastructure. The evolution of a cloud model that could be used in European health research will also have to take into account other specific aspects of the GDPR [15]. For instance, the European Commission intends to facilitate the free flow of non-personal data in the European Digital Single Market, and for health-related research participants, it codifies the ‘right to be forgotten’. This stipulates that patient donors should be able to retain control over their data regardless of technological developments. A European HRIC could be important in enabling researchers to comply with these requirements. For example, once certain conditions are met between European and international partners, including those pertaining to data protection and use, federated and hybrid clouds could facilitate the deletion of data sets once a donor exercises her/his ‘right to be forgotten’, which could minimize the necessary transfer of large raw data sets across borders, as the deletion can be performed in the original dataset and easily propagated to the relevant federated data sources.

A proper training environment for HRIC developers and users should be established

Rationale

The workshop identified the lack of trained personnel, with solid skills in both medical and data analytical fields, as one of the major bottlenecks when dealing with ‘medical big data’ [3].

Need for training and ideas

Effectively developing, operating, and maintaining the HRIC will pose serious challenges and will require the training of a new generation of data scientists who are able to navigate smoothly and efficiently between computational, security, and medical disciplines. This includes clinical researchers, bioinformaticians, data analysts, data managers, software engineers, cloud engineers, other IT-specialists, ethics officers, and data protection specialists, the latter representing an essential new field of expertise. Finding professionals who are able to cover more than one or two of the above-described disciplines is nearly impossible. Furthermore, communication between this comprehensive mix of clinical researchers, data managers, and IT/bioinformatics specialists needs to be improved, requiring a governance structure well beyond that of a standard research setting. The EU should take inspiration from existing large and successful infrastructures that foster multidisciplinary teams, such as the European Organisation for Nuclear Research (CERN) [46, 47]. Thus, it is necessary to rethink the training and education of health professionals and to update them with the HRIC in mind, considering both international standards and practices for data sharing, as well as national environments and regulations.

Multiple funding mechanisms are required to drive the development of the HRIC and to support its broad use in research projects

Rationale

Delivering the HRIC will require an ambitious reshaping of the European landscape for health data and research through appropriate funding schemes, which will enable the transformation of fragmented ICT resources and project-centric solutions for data access and governance into a long-term, coherent service ecosystem that can be accessed by users transnationally.

Need for innovative public–private funding initiatives

The HRIC needs a trusted and transparent innovation approach that recognizes the importance of a clear, long-term ambition in the program to support the participation of industry and small-to-medium enterprises (SME) in joint projects with a broad set of societal actions. In particular, there is a need to support the EU ICT industrial/SME innovation ecosystem in order to demonstrate the benefits in advancing data sharing, integration, and analysis across Europe, for the benefit of all citizens, thus creating a foundation for attractive private investments.

For this purpose, targeted EU-funding mechanisms also involving private investors need to support the development of HRIC-compliant services for data sharing and analysis in health-related research projects (i.e., through reimbursement of storage and computing costs) with incentives to reuse and extend existing infrastructures that favor national HRIC participation rather than rebuilding and fragmenting solutions. Moreover, the EU ICT industrial ecosystem must be supported in order to alleviate the risks associated with storing and sharing data across cloud systems operated by non-EU companies. The EU has established a strict privacy and ethics policy through the implementation of the GDPR legislation, which is binding for all operators active in the EU territory [48,49,50,51].

European funders, science policy makers, and other actors need to develop mechanisms that bring together experience gained and lessons learned from a large portfolio of pathfinding projects and must build on current investments, thus leveraging existing project outcomes. This requires an inclusive and integrative approach with programs that bring together many different actors into the HRIC, because its construction needs interdisciplinary collaboration with expertise from many disciplines, including economics, ICT, biomedical and health, social sciences, and policy. In particular, frameworks for public–private partnerships such as IMI have shown a way to include industry in open transparent projects that also include patients and other public bodies, SMEs and European researchers. Many of the mechanisms proposed in the Lamy report (prioritize research and innovation in EU and national budgets, build a true EU innovation policy that creates future markets, rationalize the EU funding landscape and achieve synergy with structural funds …) [52] and in the development of the Horizon Europe ‘Missions’ [53] would also be well suited to the development of the HRIC, and would help to bring together initiatives from the many funders and national and regional stakeholders. Other opportunities, such as those proposed to be included in the Horizon Europe strategic workplan (e.g., the European Information Cloud, the European Institute of Technology, and the European Council for Health Research [54, 55]), should be of interest to those seeking to deploy innovations together with industry at the European level [56].

Furthermore, future programs need to create incentives such that developed solutions are transformed into long-term reusable resources and to make sure that this infrastructure is deployed across the EU with development informed by ongoing research projects. The European Joint Programme on Rare Diseases (EJP-RD) [56] provides a good example of how infrastructure development can be linked with research projects at national and international levels. Like the EJP-RD, the European Strategy Forum on Research Infrastructures (ESFRI) can play a role in the development of the HRIC. Two further aspects of the EJP-RD are worth noting: the program has a strong emphasis on the importance on the diverse workforce required, with a training program that stretches beyond academia and research networks to reach a broad set of individuals in health systems and the education sector. Moreover, the HRIC should fund as broadly as the EJP-RD and should recognize that successfully addressing many of the identified challenges will require a diverse portfolio of projects that avoid any artificial boundary between biomedical and health research. Horizon Europe should allow for linkages between the HRIC, ESFRI, and other themes of Horizon Europe and, importantly, between the HRIC and other funding sources such as the European Structural and Innovation Funds (ESIF) and the cutting-edge basic research successfully supported by the European Research Council (ERC) during the past decade [57, 58].

The HRIC should enable investments in product development for future health-care solutions and should allow health care providers to procure such solutions. People need to be an integral part of the innovation vision in which the HRIC supports a highly skilled future workforce that makes Europe attractive for locating R&D investments. The experience gained in IMI public–private partnership infrastructure projects such as eTRIKS and the European Medical Information Framework (EMIF) should be leveraged. Finally, the current and future EU Framework Programmes for Research and Innovation (Horizon 2020 and Horizon Europe) should consider mobilizing funds to support novel pilot actions and the pooling of data and resources across the EU, and should demonstrate the benefits in advancing data sharing, integration, and analysis across Europe, for the benefit of all citizens.

Conclusions, recommendations, and action points

Clouds are increasingly becoming a key venue for enabling and hosting European and international collaborations, benefitting from the ability to hold data securely in a single location (or in few locations) and enabling collaborative research on the computational infrastructure used for analysis. In conclusion, a cloud-based federated data storage solution, with interoperable services for data-access to local repositories and modular environments that can be configured for a given use case, seems to match the data needs of the EU research and medical institutions and of all other stakeholders. The choice of cloud technology provides the ability to manage rapidly growing datasets and provides users with access to the massive computational infrastructure needed for analysis. The federated, cloud-based research environment described in this paper—HRIC—would represent an added value to the entire biomedical and bioinformatics community, because single research institutes and medical institutions lack sufficient infrastructure capacity. The establishment of a transnational HRIC will allow the European research community at large to contribute to the global international leadership required to address societal and scientific challenges through transnational collaborations. In order to ensure the effective and efficient implementation of the European HRIC, the workshop participants endorsed the five recommendations and action points presented in Table 2 to the EU and all stakeholders.
