A joint conference organised by

All roads led to Porto for health data enthusiasts

More than 200 participants sat down in carefully curated sessions focused on the latest topics in health data quality, its challenges and incentives.

It is well recognised by all stakeholders, that health data offers huge opportunities to accelerate research and to improve care.

  • Patients and clinicians want their health data to be safe, rapid and evidence based.
  • Healthcare institutions and authorities must learn from their data.
  • Public health agencies need reliable data to guide healthcare and prevention programmes.
  • Regulators and health technology assessment agencies want to be able to trust real-world evidence in decision making.
  • Research urgently needs greater access to high-quality data to foster innovation.


The value of the massively growing health data volumes to advance healthcare and clinical research is beyond dispute. Although the change to this data-driven environment, this “big data revolution” has not reached its full potential due to concerns related to the quality of health data. Data quality is about having confidence in the quality of the data that you record and the data you (re)use. And the most important condition for trustworthy use and re-use of data is obtaining high-quality data. In the healthcare setting, enormous amounts of data are generated at every point of interaction.


Obtaining high-quality data in this healthcare setting seems evident and straightforward, unfortunately this doesn’t appear to be the case in practice. Data quality is a dynamic complexity, an ever-changing requirement that needs to be redefined over time and over different projects. Because of this complexity, there are enormous challenges to overcome before achieving high quality data. Challenges involving the management and improvement of people, processes, policies, measurements, technologies and standards.


The aim of this summit was to demonstrate the importance of the quality of healthcare data, how to measure data quality and how to improve it. Whether for primary use or secondary use, data quality is a universal requirement. It is the most important real-world data challenge. Data without quality can neither contribute value nor serve any useful purpose.

In addition, the summit combined the different perspectives of data scientists, healthcare professionals, patients and governance to find the much-needed consensus for the next generation of healthcare systems.
