Income surged in 2014 at Minnesota's biggest hospital operators.
As a group, 10 of the largest hospital systems in Minnesota saw operating income jump by 38 percent in fiscal 2014 compared with the previous year, according to a Star Tribune analysis. Combined earnings hit the highest mark in four years.
Two hospital systems spearheaded the increase, sparking income growth by putting the brakes on hiring.
More broadly, hospitals cited a complicated mix of factors ranging from a bad flu season and increased income through mergers, to better reimbursement from health insurance companies.
Hospitals offered a mixed verdict on the effect of increased health insurance coverage under the federal health law. Some said it made a difference, while others downplayed the financial impact.
Collectively, the 10 large systems posted operating income of $628.7 million on revenue of $17.8 billion, up from collective income of $455.5 million the previous fiscal year.
Analysts say they haven't yet finished tallying financial results across all hospitals in 2014, but said the Minnesota results seem on par with, if not a little better than, those reported elsewhere.
"Minnesota hospitals have always done relatively well," said Kevin Connolly, an analyst with Moody's Investors Service, who cited the state's healthy economy and high rate of health insurance coverage. "Minnesota has been ahead of the game in terms of how they manage their costs."
