Income from providing medical care and selling health insurance fell $83 million to $72 million for the three-month period ending Sept. 30 at the University of Pittsburgh Medical Center, for an operating margin of 2.9%. At the same time, operating revenue rose $39 million to $2.44 billion from a year ago, according to results released on Thursday. Government incentive payments for electronic medical records' adoption and the sale of data were among the factors that pushed up operating income during the first quarter of fiscal 2012.
