The parent of Northwestern Memorial Hospital's acquisition of Lake Forest (IL) Hospital has been completed. The 215-bed medical center will become a "wholly owned entity of Northwestern Memorial HealthCare," which includes Northwestern Memorial Hospital, representatives from the Chicago-based Northwestern said in a statement. The deal, which has received state and federal regulatory clearance, includes a commitment to building a new Lake Forest Hospital or replace the medical center within the next decade. Northwestern Memorial will also continue Lake Forest's expansion of its Grayslake campus, which includes an emergency center and outpatient services, the Chicago Tribune reports.
