Providence Health & Services, Southern California has received approvals from church and state officials to take over Santa Monica’s St. John’s Health Center and the John Wayne Cancer Institute, the hospital system announced on Thursday. The California Attorney General’s Office approved the transaction with SCL Health System after the Holy See, the governing office of the Catholic Church, granted its permission to the sponsorship change between the two Catholic hospital chains. The facility will change hands on Saturday. The 234-bed hospital, which will be renamed Providence St. John’s Health Center, was founded in 1942 by the Sisters of Charity of Leavenworth, and has been part of the Denver-based SCL Health System. After studying bids by several Catholic-affiliated entities, SCL entered into exclusive negotiations with Providence last May and signed the agreement in September. St. John’s will become the sixth area hospital operated by Providence Southern California, a Mission Hills-based unit of Providence Health & Services of Renton, Wash. It owns hospitals in Mission Hills, Burbank, Tarzana, Torrance and San Pedro. “This is a very exciting moment for Providence and for Providence St. John’s as we unite the legacies of our founders to continue advancing the art and science of quality and compassionate health care,” said Michael Hunn, chief executive of Providence Southern California, in a statement. Terms of the deal between the two non-profits were not disclosed. A private ceremony is planned Friday to mark the transition.
