Depth, breadth and quality to support your research needs

Capturing a complete picture of the patient health care journey does not happen with claims data alone. Clinical research, medication adherence analysis, value messaging and commercialization strategies all depend on data that sufficiently reflect what occurs during diagnosis and treatment.

Unlike niche data aggregators, Optum consolidates and enriches electronic health record (EHR) data that span therapeutic areas and sites of care. Our scale — with over 100 million unique lives — lets researchers drill down into the treatment patterns and resulting care outcomes that matter for the population they're studying.

Optum remains at the forefront of using natural language processing (NLP) to provide meaning, structure and context to clinical notes. That means more opportunities for enrichment and more precise insight to help you understand where your treatment has the greatest opportunity to impact patient outcomes.
