NYC dumps for-profit jail health care provider after investigation faults contractor's care

NEW YORK, N.Y. - New York City is dumping the private company that delivers health care in its jail system after a year of scrutiny over the high-profile deaths of mentally ill inmates.

Mayor Bill de Blasio (dih BLAH'-zee-oh) announced Wednesday the city's public hospital system will take over medical and mental health care at Rikers Island when Corizon Health Inc.'s contract expires Dec. 31.

The decision comes the same day a city investigation revealed Corizon's faulty hiring practices, uncompleted background checks and questionable medical practices.

In statements, Corizon disputed the Department of Investigation report, saying it was misleading and improperly shifted responsibility from city agencies that oversee the jails to the company.

It also said it was disappointed its contract won't be renewed. The Brentwood, Tennessee-based company has provided care in city jails since 2001.
