Frequently Asked Questions

St. Anthony’s Medical Center and Mercy officially affiliated on June 1, 2017, based on their shared mission, values and heritage as Catholic health care providers and their commitment to providing quality, compassionate care. On Oct. 1, 2018, St. Anthony’s hospital adopted the name Mercy Hospital South. Following are answers to some questions you may have about the affiliation.

When the affiliation was originally announced, it was stated that St. Anthony’s would keep its name for five years. Why was the name changed so much sooner?

In the original affiliation agreement, announced February 2017, St. Anthony’s Board of Directors was given the option to keep the St. Anthony’s name for up to five years, unless they decided to change the name sooner. When the affiliation became official that summer, Mercy leadership conducted listening sessions with community leaders, physicians and co-workers. They overwhelmingly voiced the desire to change the name to Mercy sooner. Almost one year after the affiliation was announced, St. Anthony’s Board of Directors made the decision to change the name to Mercy Hospital South effective Oct. 1, 2018, demonstrating a commitment to provide a unique, consistent and high-quality experience everywhere Mercy serves. Moving forward with the name change signifies that we stand together as a united ministry, both in mission and now in name.

The specific date for adoption of the new Mercy Hospital South name was chosen to coincide with the transition to Mercy’s electronic health record system, which supports Mercy’s ability to provide coordinated, seamless care to patients across all Mercy facilities.

St. Anthony’s has a rich heritage in the community. How will that history be preserved?

Mercy is committed to preserving St. Anthony’s rich heritage through permanent displays both inside and outside the hospital.
