A $112 million expansion of Shawnee Mission (KS) Medical Center will open to patients at the end of January. The six-floor, 265,000-square-foot wing gives added space to the emergency, intensive care, and cardiac departments, officials said. The critical-care services expansion, which is connected to the existing hospital, also will provide an updated, patient-friendly space, Samuel H. Turner Sr., the hospital's president and chief executive officer, said.
