Semantic Technology to Ensure FAIR patient Data in Africa

Created on:


November 14, 2023

LUMC and LUMC Global was represented at the 2023 Conference of the American Medical Informatics Association which opened on 12 November. Prof. Mirjam van Reisen, Prof FAIR Data Science and Erik Schultes, presented at the scientific panel on “The CEDAR Workbench: Semantic Technology to Ensure FAIR Data” alongside Mark A. Musen, M.D. from the Center for Biomedical Informatics Research, Stanford University School of Medicine, Stanford; Anthony L. Juehne, from the Office of the Director, National Institutes of Health, Bethesda; and  Rachel L. Richesson, University of Michigan Medical School, Ann Arbor.

The presentations focused on the LUMC-research on the curation of medical data to ensure data is Findable, Accessible (under well-defined conditions), Interoperable and Reusable (FAIR) and Federated AI Ready.

The Research programme of VODAN of which Prof. Van Reisen is the PI has tested the potential of knowledge integration with data held in residence, within the health facility. The data is annotated with semantic attributions and is machine-actionable, produced in computer readable language. The project has deployed in 90 health facilities across 8 African countries, demonstrating the potential of secure, ethical patient data curation, in which the data does not leave the health facility or the country. The data is stored securely and can be visited for improvement of quality of care within the health facility. The data can also be visited for surveillance purposes across the health facilities, located in different geographies and residing under distinct regulatory frameworks which are respected alongside GDPR as the base standards for personal data protection.

The federated data that VODAN helps produce belong to the health data space, in which the data can be re-used and used for interoperable purposes, if permission is provided by the data producer and/or data subject. This provides a sustainable architecture in which the costs of data production and curation can be covered by the value generated from the re-use for new insights by other customers (under stringent permission controls). The architecture represents a granular source from patient health records,  as a basis of a learning health care system.

Dr. Schultes presented how sets of research findings and data can be retrieved by indexing according to FAIR principles, which is supporting the work of research funders, such as ZonMw and NWO in The Netherlands. Representing the Go-FAIR Foundation, he presented the power of training of data stewards in establishing FAIR communities, to assist data integration across domains. The Metadata-for-Machines training has helped create training of trainers that support the introduction of FAIR-data principles in new communities. The collaboration with Stanford University Cedar for data annotation has been helpful in utilizing the services required.

A discussion on the importance of metadata and the production of data as FAIR at the source, produced in machine-actionable form is critical for further knowledge-integration. The FAIR home with its roots in LUMC and Leiden Global made an inspiring presence with use cases being proudly presented and discussed in the academic seminar on the opening day of AMIA.

Kick-off Interdisciplinary Thesis Lab ‘Sustainable Hospitals’

February 17, 2022

‘How do we create a sustainable hospital?’ This is the main question the Interdisciplinary Thesis Lab ‘Sustainable Hospitals’ centers around. On February 9th, eleven (including international) master students have started their master thesis research project related to this very question. Medical Delta’s Thesis Lab and the LDE Centre for Sustainability will supervise these students during their research.

LUF-beurs Prof.dr. A.E. Meinders Fonds

February 6, 2024

Be aware: grant open to both Dutch and English speaking individuals!

LUF scholarships from the Prof. Dr. A.E. Meinders Fund provide support to talented students and PhD candidates in the field of internal medicine. These scholarships are intended for conducting scientific research, such as a portion of a doctoral study or a scientific internship, with a focus on patient care abroad. Preference is given to clinicians over “laboratory assistants.”

Introducing our first LUMC Global PhD candidate: Jeremia J. Pyuza

June 21, 2021

Creating new sustainable relationships between the Leiden University Medical Center (LUMC) and international counterparts is one of the core elements incorporated in the LUMC Global strategy. Through multiannual partnerships in (bio)medical research and education, we aim to contribute to global healthcare improvement. We’re therefore very excited to announce our first Global PhD candidate, Jeremia J. Pyuza, who’s at the centre of a newly set-up collaboration between Kilimanjaro Christian Medical Centre (KCMC), Tanzania and the LUMC.
