Southern Illinois Healthcare (SIH) is a not-for-profit regional health system serving the southernmost 16 counties of Illinois, with a primary service area of approximately 233,199 residents across seven counties and an extended reach into the lower 16 counties of the Illinois Delta Region. The system operates four hospitals — SIH Memorial Hospital of Carbondale (162-bed tertiary care, Level II Trauma Center, teaching hospital), SIH Herrin Hospital (114-bed acute care, Primary Stroke Center, region's first accredited Chest Pain Center), SIH St. Joseph Memorial Hospital (25-bed critical access with Catholic affiliation), and SIH Harrisburg Medical Center (85 licensed beds) — alongside 30+ outpatient clinics, the SIH Cancer Institute, SIH Prairie Heart Institute, SIH Brain & Spine Institute, SIH Mulberry Center (31-bed inpatient psychiatric), 10 outpatient rehabilitation locations, two urgent care sites, and the FindHelp Southern Illinois social-services platform. SIH employs 4,000+ staff and ~700 physicians and advanced practice providers across 60 specialties.

The system's core technology stack centers on advanced third-party medical hardware: da Vinci Xi robotic surgery (Herrin), Ion robotic bronchoscopy (Memorial), Aquablation for BPH (St. Joseph), StealthStation surgical navigation and O-arm O2 imaging for neurosurgery, the region's first 3T MRI, a hybrid operating room at Memorial, and AlterG anti-gravity treadmills at two rehabilitation sites. Patient access is delivered through MyChart-enabled virtual care (On-Demand Video Visits and ~$32 E-Visits), online scheduling, walk-in clinics, and the SIH Central Referrals team coordinating more than 50 specialty service lines from regional providers.

SIH generates revenue through patient care services across inpatient, outpatient, surgical, diagnostic, rehabilitation, cancer, cardiac, neuroscience, behavioral health, and maternity lines, and reinvests surplus into community benefit ($1.3B+ cumulative since 2014 in charity care, unreimbursed care, and community programs). The system is governed by its own Board of Trustees with no parent company, maintains strategic affiliations with Prairie Heart Institute, SIU School of Medicine, Siteman Cancer Network, and BJC Collaborative, and holds exclusive regional designations including sole Level II Trauma Center, sole comprehensive cancer center, sole OB Emergency Department, and sole non-state inpatient mental health facility across the southern 16 counties.
