A European research project designed to make hospital cardiology data more accessible for research has entered a new phase.
The DataTools4Heart (DT4H) platform is now being tested with real clinical data at seven hospitals across Europe.
The aim is to enable researchers to analyse data from multiple institutions without transferring sensitive patient information between them.
DataTools4Heart uses a federated approach.
Rather than collecting patient information in a central database, data remain within the hospitals where they were generated.
Analytical tools and machine learning models are brought to the data instead.
The platform combines several technologies.
These include tools for standardising and harmonising data, multilingual natural language processing to extract information from clinical text and federated machine learning for training models across different institutions.
