Two health providers have announced they intend to create a new regional health-care system.

Catholic Health Initiatives (CHI), a large national hospital chain that includes Tacoma-based Franciscan Health System, and PeaceHealth, operating in Washington, Oregon and Alaska, have announced they intend to create a new regional health-care system.

The new system would include seven CHI hospitals in Washington and Oregon and nine PeaceHealth hospitals (including one in Friday Harbor scheduled to open in November).

CHI, headquartered in Colorado, operates in 19 states, running 76 hospitals and 40 long-term-care and residential facilities, along with nursing colleges and home-health agencies.

Leaders of the two organizations, in a statement, said the plan to partner was prompted by a changing health-care environment that demands a “more coordinated, integrated approach” to care delivery, economies of scale and the ability to accept more financial risk to care for certain populations, such as Medicaid recipients.
