University of Connecticut officials touted an ambitious proposal to partner the financially troubled University of Connecticut Health Center with Hartford Hospital, a plan that promises to end the Health Center's habit of seeking taxpayer bailouts. But the plan also would require the state to come up with $475 million for a new hospital and spend $13 million a year in labor costs. The partnership would create a "University Hospital," and transform the Health Center from one of the smallest academic hospitals in the country to part of a major regional health center.
