 Prison Health Services, which has cared for 237,000 inmates, has had to pay millions of dollars in fines and settlements due to inadequate care.In another example, according to a former supervisory nurse of a jail operated by Correctional Medical Services (CMS), a large private contractor, the jail would often release pregnant women when they went into labor, and then arrest them again after they gave birth, in order to avoid having to pay for the inmates' medical expenses.Lack of accountability also results due to varying state and federal laws on private contractors' liability for medical abuse and neglect.
