The Advisory Board provides information to the health-care and education industries on business trends and best practices. It counts more than 2,985 hospitals, health systems, universities, drugmakers and other organizations that subscribe to its research and Web tools. Business picked up this year as organizations sought insight on the federal health-care overhaul. The economic recovery also brought clients back, as institutions looked for tips on how to cut costs and run their operations more efficiently. During the spring, the company announced the purchase of Concuity for $34.5 million. Concuity makes software for managing health-care contracts and payments.
