Democratic U.S. Sen. Edward Markey called on Wednesday, March 27, 2024, for greater oversight of a deal that financially embattled hospital operator Steward Health Care has struck to sell its nationwide physician network to Optum. The move comes as Gov. Maura Healey has said state monitors are keeping eye on the nine health care facilities operated by Steward Healthcare in Massachusetts. Before the sale can be completed, the Massachusetts Health Policy Commission must review the proposal.
