Pharma and payors: In 2011, AstraZeneca established a four-year partnership with WellPoint’s data/analytic subsidiary HealthCore to conduct real-world studies to determine the most effective and economical treatments for chronic illnesses and other common diseases. AstraZeneca will use the HealthCore data, together with its own clinical-trial data, to guide decisions on where to invest its research and development dollars. The company is also in talks with payors about providing coverage for drugs already on the market, again using the HealthCore data as evidence. Again, this relates to the right care pathway.
