What began in 1917 as Middletown Regional Hospital is now the gleaming new Atrium Medical Center, a striking addition to the booming hospital competition in Butler County.

Since it opened last year, people may have heard about Atrium’s birthing and rehabilitation centers, or the specialized departments for cardiology, women’s health and sports medicine. But those services are just part of this project’s beginning.

Atrium is one component in what’s called Premier Health Campus-Middletown, named after Premier Health Systems, which also owns and operates Miami Valley Hospital and Good Samaritan Hospital in Dayton. At the 190-acre Atrium site, Premier plans to build within two years a Behavioral Health Pavilion with inpatient and outpatient care, and a new surgery center with four operating rooms.

Atrium also is demonstrating how advanced oncology services can be delivered in suburban locations. Beginning with cancer diagnosis, the Compton Cancer Center can use of PET scanning (positron emission tomography).

For patients diagnosed with cancer, the center has a chemotherapy infusion unit and a multi-million dollar IMRT (intensity-modulated radiation therapy) system, which pinpoints cancerous masses and minimizes radiation damage to healthy tissue.
