The Fenty Administration also expanded health care coverage for the uninsured and established thousands of units of affordable housing, while creating the "Housing First" program to provide permanent supportive housing for the district's homeless. The administration also reduced the backlog of Child Protective Services (CPS) investigations by improving the retention of social workers, increasing recruitment of social workers to fill vacancies, and building a quality, experienced leadership. Additionally, the Fenty Administration improved the delivery of emergency medical services. It also finalized the sale of Greater Southeast Community Hospital (now United Medical Center) in a public-private partnership that kept the facility open for patients east of the Anacostia River.
