Existing Data Sources for Clinical Epidemiology: The PHARMO Database Network.

Area of Science:

• Health Informatics
• Population Health Research
• Real-World Data Analysis

Background:

• The PHARMO Database Network aggregates anonymous electronic healthcare data from various Dutch primary and secondary care settings.
• It integrates data from general practitioners, pharmacies, hospitals, and clinical laboratories.
• Linkage with external registries like Cancer, Pathology, and Perinatal registries enhances data comprehensiveness.

Purpose of the Study:

• To provide a comprehensive view of the patient journey and healthcare utilization in the Netherlands.
• To enable longitudinal research on over 10 million residents, averaging 12 years of follow-up.
• To facilitate research access under strict privacy and governance protocols.

Main Methods:

• Utilizes a population-based network of linked electronic healthcare databases.
• Employs probabilistic linkage with validated algorithms for patient-level data integration.
• Collects longitudinal data from multiple healthcare settings and external registries.

Main Results:

• The network covers more than 10 million Dutch residents with an average follow-up of 12 years.
• Data is anonymized and linked across primary care, secondary care, and specialized registries.
• Access is restricted to PHARMO Institute researchers and academic affiliates, ensuring data privacy and governance.

Conclusions:

• The PHARMO Database Network is a valuable resource for population health research in the Netherlands.
• Its extensive, longitudinal, and linked data enables in-depth analysis of patient journeys.
• Strict governance ensures ethical and privacy-compliant research access.
