The Health Improvement Network

The Health Improvement Network (THIN) is a prominent provider of anonymized real-world data and electronic health records (EHR) sourced from a large network of primary care practices across the UK and Europe. Operating as a subsidiary of Cegedim, THIN maintains a longitudinal database that captures comprehensive patient histories, including diagnoses, prescriptions, and laboratory results. This data is extensively used by pharmaceutical companies, academic institutions, and regulatory bodies for epidemiological research, drug safety monitoring, and health outcomes analysis. THIN's platform supports the development of evidence-based medicine by providing insights into disease progression and the real-world effectiveness of various treatments. The network covers millions of patients, offering a representative sample of the population for large-scale clinical and observational studies.
