We have developed a multi-dimensional data collection methodology. Our first-party research includes over 650,000 research calls and 4 million email outreaches annually. We collect data from more than 20,000 government and regulatory sources and more than 250,000 websites, journals, publications, news articles, job postings, and other public information sources using proprietary automated processes. We also collect third-party data, including information on many billions of institutional and professional claims covering many millions of patients.
