Executive summary Developing a global health data network will enable data to fulfil its potential to transform health systems and delivery. In the evolving landscape of global healthcare, health data stands out as an immensely powerful yet largely untapped resource, poised to revolutionize patient outcomes, broaden healthcare access and enhance systemic efficiency. Despite the rapid growth in health data, much of it is not shared and remains underused – hindered by fragmented standards, uncoordinated practices and misaligned incentives – resulting in a lack of significant real- world clinical applications. This gap between data creation and practical use underscores the need for transformative health data collaboration to unlock its potential. The need for a connected health data network extends beyond enhancing current health systems to reduce patient harm and resource waste; it is also essential for reimagining the future of health through AI-driven solutions and emerging technology. While sectors outside healthcare advance in artificial intelligence (AI) and data analytics, healthcare systems remain constrained, missing critical opportunities. Compounding these challenges are systemic pressures, including rising rates of chronic disease, ageing populations and insufficient resources. These issues highlight the urgent need for a coordinated global response to align health data practices with health system objectives.This report envisions a global health data network economy – an interconnected system in which diverse stakeholders including healthcare providers, patients, pharmaceutical companies, tech innovators, governments, researchers and others collaborate to maximize the value of shared information. By enabling secure data exchange and broader access to rich datasets, this network economy can drive advances in diagnostics, accelerate research, support precision medicine and deliver highly personalized patient care. Integrating healthcare data nodes within this ecosystem would create a network worth far more than the sum of its parts. Moving towards this powerful network will require significant, concerted and coordinated effort to overcome key barriers that have prevented its formation. This paper outlines the strategic steps needed to promote trust, standardization and interoperability in building a robust health data network economy. These steps must bridge existing divisions, ensure data quality and governance and better align health data policies, practices and standards with global health objectives. Collaborative action is necessary to create a clearer pathway towards a global healthcare transformation that takes a coordinated, data- driven approach – setting the stage for sustainable improvements in healthcare for years to come.
