When the state's public health exchange launches in October, it will be confusing, a little clunky and time-consuming, say the people overseeing the launch. Wednesday, they met to focus on how to make it easier. Access Health CT's chief executive, Kevin Counihan, said that he expects "low satisfaction" among consumers at the start of the health exchange and that it could be up to three years before that turns around. As part of the Affordable Care Act, private health insurance plans for coverage will be for sale starting Oct. 1 in an online marketplace known as a public health exchange. The coverage will begin Jan. 1.
