Massachusetts hospitals face growing financial strains. Two dozen—more than a third of the state's total—lost money last year, according to a new report from the Division of Health Care Finance and Policy. Among the biggest money losers were Boston Medical Center, which posted a $25.1 million deficit, Steward St. Elizabeth’s Medical Center in Brighton, which lost $20.9 million, and Quincy Medical Center, which was $18.5 million in the red. The industry's performance was worse than in 2010, when 16 hospitals posted losses, and in 2009, when 13 were unprofitable.
