Trinity Health, one of the largest not-for-profit Catholic health systems, announced Thursday that its agreement to fully acquire MercyOne is completed, and the Clive-based health system is now a full member of Trinity Health, based in Livonia, Mich. The agreement, announced in April between Trinity Health and CommonSpirit, ended a 25-year joint operating agreement between the two not-for-profit Catholic health care organizations, with each having held 50% ownership of MercyOne. Trinity Health now owns all facilities and assets of MercyOne, including its home care, hospice and infusion locations. Operating as a part of Trinity Health, MercyOne will retain its name and brand while enhancing more integrated and unified care in the communities it serves. MercyOne includes 16 medical centers, 27 affiliate organizations and more than 420 care sites that employ more than 20,000 health care workers, including some 2,000 physicians. “Today’s closing further advances MercyOne’s vision to provide personalized and radically convenient care experience for Iowans and neighboring communities,” said Bob Ritz, president and CEO of MercyOne. “We are delighted to become a full member of the Trinity Health family, which will further our goal to be a more strongly connected system of health services. We are grateful to CommonSpirit for their support in the transition and for more than 25 years of successful partnership in Iowa. We look forward to further strengthening the mission of MercyOne.” Trinity Health operates in 25 states and cares for about 1.4 million patients annually.
