About half of Connecticut hospitals—15 out of 31—will lose part of their Medicare payments in 2018 as a penalty for having relatively high rates of patients who acquired preventable injuries and infections while hospitalized. The hospitals are among 751 nationwide that will lose 1 percent of their Medicare reimbursements in this fiscal year. The penalties are part of the Centers for Medicare and Medicaid Services’ (CMS) Hospital-Acquired Condition Reduction Program, which is part of the Affordable Care Act. The program penalizes hospitals with the highest rates of patients who got infections from hysterectomies, colon surgeries, urinary tract catheters and central line tubes. It also tallies those who suffered from blood clots, bed sores or falls while hospitalized.
