We leverage data science to integrate claims-based affiliations with our primary research to accurately identify connections between entities. Our team also harnesses natural language processing (NLP) to match NPI facilities and a proprietary geolocation algorithm to provide the physical addresses of every U.S. facility. We have also constructed a physician affiliations model that is claims-based, weighted by clinical volumes, and enriched with research and proprietary algorithms to track physician behavior over time. By integrating data across sources, our physician affiliations intelligence uncovers hundreds of thousands of previously unknown relationships between physicians and organizations. In a recent survey conducted by an independent research firm, Definitive Healthcare was ranked #1 or #2 by healthcare organizations for the top five use cases for healthcare reference and affiliation data.
