Medical Facilities holds controlling interest in five specialty surgical hospitals located in Arkansas, Indiana, Oklahoma, and South Dakota. Medical Facilities’ hospitals focus on a limited number of high volume, non-emergency surgical, diagnostic and imaging procedures. The case mix at each hospital is a function of the clinical specialties of the physicians on the medical staff and the equipment and infrastructure at each facility. Orthopedic and neurosurgical procedures represent a large portion of the case volumes at the hospitals. Medical Facilities also holds controlling interest in an ambulatory surgery center located in California. The center performs a broad range of outpatient procedures, with patient stays of less than 24 hours.
