Catholic Healthcare West, San Francisco, has acquired seven hospitals to become California's largest system, with 30 hospitals and 6,811 licensed beds.
The hospitals merged with CHW under co-sponsorship arrangements with four other congregations.
Kaiser Permanente operates 28 hospitals with 5,604 licensed beds in California. CHW also operates two hospitals with 702 beds in Henderson, Nev., and Phoenix.
Under co-sponsorship, CHW owns the hospitals and the congregations participate in governance and reserve the right to approve sales. CHW is now co-sponsored by seven congregations with assets of $4.1 billion and annual revenues of $3.1 billion.
To oversee strategic management of the seven hospitals, CHW has added two new regions to its seven existing regions. A CHW spokeswoman said plans are under way to streamline management and governance at the hospitals, but no specifics were available.
Joining CHW are 443-bed St. Bernardine Medical Center in San Bernardino and 551-bed St. Mary Medical Center in Long Beach. Those hospitals are sponsored by Sisters of Charity of the Incarnate Word, Houston.
Also joining are Robert F. Kennedy Medical Center, Hawthorne, a 274-bed community hospital sponsored by Daughters of Charity of St. Vincent de Paul, Western Province, Los Altos Hills.
The Dominican Sisters of San Rafael are contributing 312-bed St. Joseph's Medical Center, Stockton; 63-bed St. Dominic's Hospital, Manteca; and 49-bed Mark Twain St. Joseph's Hospital, San Andreas.
The remaining new member is 101-bed Mercy Hospital and Health Services, Merced, which is sponsored by the Dominican Sisters of St. Catherine of Siena, Kenosha, Wis.
The other co-sponsors are founding members Sisters of Mercy of Burlingame and Sisters of Mercy of Auburn in California; and Sisters of St. Dominic of Adrian, Mich.
