Data Resource Profile: Extramural Leiden University Medical Center Academic Network (ELAN).

The Extramural Leiden University Medical Center Academic Network (ELAN) is a data infrastructure in the Netherlands that combines healthcare data from various sources to improve patient care and health outcomes through research collaborations. The data includes information on 2.6 million individuals residing in South Holland province since 2007, with coded clinical measurements, morbidities, medication use, and social determinants of health. The document also provides data on characteristics of different countries, including population, gender distribution, age, urbanization, disposable household income, education level, and country of origin. The ELAN database contains information from general practitioners, hospitals, mental healthcare organizations, and national and municipal sources, covering medical information, pregnancies, births, and social determinants of health. The data is pseudonymized, linked across sources, and undergoes harmonization for research projects. While there are limitations to the data, researchers can request access for approved collaborative projects. [Extracted from the article]
