The new owners of River Park Hospital are promising a relentless drive for excellence in patient care, including outreach to the community’s poor and medically underserved.“If I came back a year from now and you ask ‘What has changed?’ we have failed,” Karen Springer, president and CEO of Saint Thomas Health, told the McMinnville Noon Rotary Club Thursday. Saint Thomas, a national model in the nonprofit healthcare industry, this summer completed the acquisition of River Park Hospital, along with sister facilities in Woodbury, Sparta and Smithville.River Park had been operating in recent years in a medical services relationship with the Nashville-based Saint Thomas, an arrangement that substantially enlarged the specialties available to local and area patients. Among those enhancements were rapid-response intervention for stroke victims, a behavioral health and rehabilitation unit, and expanded and strengthened ties to Saint Thomas’ famed cardiac care institute.Springer observed the mission of Saint Thomas Health — founded by the Catholic charity Sisters of Mercy — emphasizes healthcare for all people, including the poor, over monetary gain.
