MedAssets Inc.’s (NASD: MDAS) second-quarter revenue rose 54.9 percent year over year, boosted by its November 2010 acquisition of The Broadlane Group, which provides a vendor management system to the healthcare industry. Second-quarter revenue was $147.4 million, compared with revenue of $95.1 million a year ago.

When recasting last year’s second-quarter results to include Broadlane revenue, Atlanta-based MedAssets' revenue rose 6.4 percent in the second quarter of 2011.

Second-quarter revenue in the company’s “spend and clinical resource management” segment, which includes the Broadlane VMS, rose 6.0 percent to $91.6 million, when comparing it to the year-ago quarter with results recast to include Broadlane revenue.

The company’s net loss for the second quarter was $2.5 million, compared with net income of $3.3 million in the year-ago quarter. The company attributed the net loss to acquisition and integration-related costs as well as increased amortization and interest expenses related to Broadlane acquisition.
