Cook County Health and Hospitals Systems announced Sept. 27 that it has resumed 24-hour medical services at its outpatient care center in Oak Forest.

The county also said it has completed a $6 million project to offer outpatient diagnostic services at Oak Forest Health Center, 159th Street and Cicero Avenue, the former location of Oak Forest Hospital.

In June, the county health care system notified state officials that it was temporarily suspending patient services at the center between 11 p.m. and 7 a.m. because three doctors had left, and few patients were coming there during the overnight hours.

When Cook County sought approval in 2011 from the state to close Oak Forest Hospital, county officials pledged to maintain 24-hour care at the new clinic.

It was unclear what prompted the resumption of 24-hour services, and a spokeswoman for the county health system was not available for comment Sept. 27.

In a news release, the county health system also said a “transformation” of the outpatient clinic will now enable it to perform CT scans, ultrasounds and mammograms there. Its new diagnostic center includes a laboratory with six radiology suites, according to the release.

Other services now available include cardiology, gynecology, podiatry and optometry, according to the health system.

The county said more than 100,000 patients were seen last year at the center.
