Curahealth – the system with 12 long-term acute-care hospitals in Massachusetts, Arizona, Oklahoma, Louisiana, Tennessee and Pennsylvania – has announced it will close the second of its three Bay State hospitals. In August, Curahealth announced that it was closing Curahealth Hospital Boston – North Shore (Peabody) by the end of September. Now Curahealth Hospital Boston (Brighton) will be shuttered by October 25. Together the two hospitals employ about 200 people. Curahealth Hospital Stoughton will continue to operate. The system blamed the closures on declining Medicare reimbursements and low admissions.
