Capella Healthcare Acquires

Muskogee Community Hospital

Muskogee Community Hospital and Muskogee Regional Medical Center

To Become One Health System

July 1, 2012. Franklin, Tenn. – The partnership between Muskogee Regional Medical Center and Muskogee Community Hospital that will unite the hospitals into one comprehensive health system has been finalized, officials announced today.

Both hospitals, located in Muskogee, Okla., are now operated jointly by Capella Healthcare, which entered into a long-term lease and assumed management of Muskogee Community Hospital effective today.

“We are excited to welcome Muskogee Community Hospital to the Capella family of hospitals,” said Dan Slipkovich, Chief Executive Officer of Capella Healthcare. “The goal of this collaboration is to be able to better meet the healthcare needs of Muskogee and the surrounding communities as we respond to the call for closer collaboration between providers under healthcare reform. By working together, we can improve access to healthcare for our community as well as enhance quality and efficiency of care.”

This will be achieved by merging the strengths and capacity of both hospitals into a unified system of healthcare providers to serve Muskogee and the surrounding region. The structure of this single comprehensive organization will create opportunities for expanding access to care.

Capella has operated Muskogee Regional Medical Center since 2007, when it entered into a 40-year long-term lease of the 275-bed acute-care hospital. Muskogee Community Hospital, a physician-owned and operated facility licensed for 45 beds, was opened in 2009. Both hospitals are accredited by The Joint Commission.

“This partnership will allow us to enhance existing services and eventually attract new services for the region we serve,” said Kevin Fowler, Chief Executive Officer of Muskogee Regional Medical Center, who assumes the position of CEO for the new system. “By combining the operations of these two facilities, we will be in a better position to serve the community and to attract patients who otherwise are leaving Muskogee for care. We are driven by one goal above all others – to build the strongest possible healthcare system that puts quality patient care first.”

Over the next 30-60 days, the combined organization will enter a transition period. During this time, the Transition Team will be working closely with physicians and staff to determine the smartest ways to integrate care and to determine which services will be offered at each campus.
