is the CMI proprietary prescriber database, methodology, and technology. It is unlike any other in our industry as it overlays actual HCP media usage against a complete database of HCPs at the individual ME/NPI level in the US, including demographic data, practice location, health system and hospital affiliations, and more.

Years of careful analysis of individual physician media preferences and behavior have culminated in ByDoctor® to create this sophisticated predictive database that enables CMI media teams to anticipate the most efficient and effective ways to reach their target audiences. Over 1.5 million healthcare professionals are included, with views into 26 physician specialties, nurse practitioners, physician assistants, RNs, pharmacists, medical students, and other prescribers.
