Business model
IMS Health was best known for its collection of healthcare information spanning sales, de-identified prescription data, medical claims, electronic medical records and social media. IMS Health's products and services were used by companies to develop commercialization plans and portfolio strategies, to select patient and physician populations for specific therapies, and to measure the effectiveness of pharmaceutical marketing and sales resources.
