Centralia, Illinois – Opened in 1992 as the first sleep services center in the Southern Illinois region, SSM Health in Southern Illinois Sleep Services sees continued growth and advancement over three decades later.

In addition to a full remodel of its sleep centers at both SSM Health St. Mary’s Hospital in Centralia and SSM Health Good Samaritan Hospital in Mt. Vernon in 2019, Sleep Services at SSM Health in Southern Illinois provides the utmost care through a dedicated and highly qualified staff that only continues to grow.

“We are blessed in our region. We have two board-certified sleep specialists, one in Mt. Vernon and one in Centralia. That is not something you see very often. All our staff are either registered by the Board of Registered Polysomnographic Technicians, or are in the process of getting that registry, which means they are of a high standard,” said Andy Davis, manager of Neurology and Sleep Services. “We even have a pediatric sleep specialist that reads pediatric studies for us. We are one of the few sleep centers in the Southern Illinois area that has a pediatric sleep specialist contracted with us.”

Davis, who has worked with SSM Health in Southern Illinois since the early 1990s, said the number of sleep disorder cases treated by Sleep Services continues to rise as awareness of these conditions grows.

“More and more people are being diagnosed with sleep apnea and other sleep disorders,” said Davis. “Sleep apnea is the most common of them, but there are 88 different sleep disorders. That ranges from sleep apnea to things like restless leg syndrome and parasomnia.”

Speaking on the department’s need for additional staff, Davis said, “We have four sleep technicians for the entire region, and we are getting ready to hire another. As we continue grow, we will continue to hire more personnel.”

According to Davis, SSM Health in Southern Illinois Sleep Services has conducted over 20,000 sleep studies in SSM Health St. Mary’s Hospital in Centralia alone since opening in 1992.
