Two U.S. hospital operators said on Tuesday technology problems bedeviling the federal government's online health insurance marketplace were gradually diminishing and will not stop them from pushing ahead with plans to provide care to those who sign up. "If any company had three years' notice about having a website functioning for a major product launch on October 1, it would have worked. It's frustrating that it did not work," hospital operator Tenet Healthcare Corp's Chief Executive Trevor Fetter said in an interview with Reuters following the company's third-quarter earnings conference call.
