After a year of cutting jobs, freezing pay, and delaying new construction, hospitals in the Minneapolis-St. Paul area turned their businesses around in 2009 and appear to be back in the black. Collectively, net income for hospitals swung to $327 million for the first three quarters of 2009, compared with a loss of $42 million during the same period in 2008, according to the Minnesota Hospital Association, which surveyed 22 hospitals.
