A trio of hospitals teamed up with insurer Harvard Pilgrim Health Care to establish a new company that will enable customers to analyze clinical and financial data. Dartmouth-Hitchcock, Elliot Health System and Frisbie Memorial Hospital are joining with Harvard Pilgrim Health Care to create a new analytics company to manage the clinical and financial data across the organization. The new company, named Benevera Health, is the latest in the rising use of data as a tool for population health management and lowering costs. Last month, the Blue Cross Blue Shield Association said it planned to create a huge database of healthcare claims to spot trends that could be used to control costs.
