OMOP, the Observational Medical Outcomes Partnership, is a collaborative research initiative dedicated to advancing the field of health informatics. It plays a significant role in promoting standardized approaches to analyzing observational health data. OMOP fosters collaboration among diverse stakeholders—including researchers, healthcare professionals, and data scientists—to generate valuable insights and evidence for healthcare research. OMOP’s efforts enhance the understanding of real-world outcomes, treatment patterns, and healthcare practices through the systematic analysis of large-scale observational health datasets. An OMOP Database is a standardized data framework to enable health data to be shared for research purposes across multiple organizations.
