Half of CT hospitals will be penalized by Medicare this year for poor infection and patient injury performance last year, according to CMS. Among the states, only Delaware has the same poor performance. Started in October 2014, the program was created by the Affordable Care Act to improve the quality and safety of hospital care. Only 16% of hospitals in Massachusetts will be penalized. The fifteen CT hospitals that will be penalized this year include Day Kimball, Waterbury, Johnson Memorial, Bridgeport, Charlotte Hungerford, Rockville, St. Mary’s, Midstate, Windham, Yale-New Haven, Hartford, Norwalk, John Dempsey, Connecticut Hospice, and Masonicare.
