Slidell Memorial Hospital and Ochsner Health System kicked off a partnership Tuesday that was first announced in April.

Bill Davis, chief executive officer of Slidell Memorial, will oversee operations of both hospitals, Ochsner President and CEO Warner Thomas said.

Brad Goodson, chief executive officer of Ochsner Medical Center North Shore, will have expanded duties as chief executive officer of the north shore region. He will lead the integration of the two hospitals and growth efforts on the north shore and in Mississippi — including seeking new potential partners, Thomas said.

Officials from both hospitals have stressed that the relationship between the public, not-for-profit hospital and Ochsner is not a merger or an acquisition.

The partnership was put on hold while the Louisiana Attorney General’s Office reviewed the plans. State law specifies that the attorney general must review mergers and acquisitions involving public, not-for-profit hospitals like Slidell Memorial. Hospital officials said the review was sought out of “an abundance of caution,’’ and the attorney general gave the go-ahead in late December.

Slidell Mayor Freddy Drennan, the only elected official who spoke, said initially he wasn’t happy about the plan, which he referred to repeatedly as a merger. He said he was convinced that the move will be a good one for the city.

Davis, who followed the mayor, lauded the value of the partnership, which he stressed is not a merger or acquisition. The relationship puts the hospital in the best position to withstand increasing pressures and increase health care access and quality. “We’ll do more for the community together than apart,’’ he said.

David Mannella, chairman of Slidell Memorial’s board, said the hospital will continue to be an independent community hospital governed by its own board.
