MultiCare Health System will acquire Yakima Valley Memorial Hospital under an agreement signed Friday. Memorial will become a wholly owned subsidiary of MultiCare in early 2023, when its name will change to MultiCare Yakima Memorial Hospital. Under the agreement, MultiCare will invest in new programs, implement an integrated electronic health record, strengthen the hospital's role as a regional health care hub and "help provide a sustainable future for Yakima's only hospital," a news release said.
