Memorial Hospital East, now operating as Memorial Hospital Shiloh, is a 94-bed, all-private suite, full-service hospital located at 1404 Cross Street, Shiloh, IL 62269. Opened on April 12, 2016, it was only the second new hospital to receive Certificate of Need approval in Illinois in more than 20 years at the time of its opening. The hospital is part of Memorial Regional Health Services (MRHS), a non-profit organization within BJC HealthCare — one of the largest nonprofit health care systems in the United States. Designated as a Magnet hospital for nursing excellence since 2018, Memorial Hospital East has earned national recognition for cardiac care, patient safety, and overall hospital quality.

History and Development
Memorial Hospital East was five years in development before its April 2016 opening, having received unanimous approval from the Illinois Health Facilities and Services Review Board in 2011 — an unusually swift outcome for a state with strict Certificate of Need regulations.
Planning for the hospital began in 2011 when Memorial Hospital filed a Certificate of Need with the Illinois Health Facilities and Services Review Board (IHFSRB). The approval was unanimous and represented only the second new hospital project approved in Illinois in over two decades, reflecting both the strength of the community need and the quality of the application. Construction concluded in December 2015, and a Transition Occupancy Plan implemented in early 2015 provided training for staff and procurement of equipment and supplies well ahead of opening day.
The hospital was built to serve the rapidly growing O’Fallon and Shiloh communities in southwestern Illinois, located eight miles east of the existing Memorial Hospital Belleville campus and adjacent to Interstate 64. The facility was designed as a 207,212-square-foot hospital in a natural setting, offering the region a full-service, all-private suite environment from the date of opening — a design standard that distinguishes it from older regional hospitals converted from semi-private configurations.
Memorial Regional Health Services, the non-profit parent of Memorial Hospital East and Memorial Hospital Belleville, was formed at the beginning of 2016 as part of a strategic affiliation between BJC HealthCare and Memorial Hospital. This partnership created a jointly owned organization through which BJC’s clinical resources, WashU Medicine physician partnerships, and Siteman Cancer Center access became available to southwestern Illinois patients. A second Medical Office Building housing the Siteman Cancer Center on the Shiloh campus opened in January 2020.
Campus and Facility Overview
The 207,212-square-foot hospital features 94 all-private patient rooms, four surgical suites, a cardiac catheterization lab, an ICU, an emergency department with twelve rooms, and two Medical Office Buildings on the same campus.
The hospital’s inpatient capacity includes 72 medical/surgical rooms, six intensive care unit beds, and 16 LDRP suites in the Family Care Birthing Center — all private. The Emergency Department features six treatment rooms and six observation rooms, positioned for direct access to the Cardiac Catheterization Lab and Radiology. Four surgical suites and two dedicated cesarean section rooms support both inpatient and outpatient procedures.
In October 2017, a 70,500-square-foot Medical Office Building opened on campus, providing space for primary care and specialty physician practices, a lab draw center, general radiology and CT services, and The Harold and Dixie LePere Breast Health Center. A second Medical Office Building housing the Siteman Cancer Center opened in January 2020. Together the two office buildings consolidate outpatient specialty access on the Shiloh campus, reducing the need for patients to travel to Belleville or St. Louis for oncology, breast health, and specialist services.

Cardiac Care and Awards
Memorial Hospital East has received Healthgrades’ America’s 100 Best Hospitals for Cardiac Care Award, America’s 250 Best Hospitals Award, and Patient Safety Excellence Award, reflecting superior outcomes in heart bypass surgery, coronary interventional procedures, heart attack treatment, heart failure, and heart valve surgery.
The cardiac catheterization lab at Memorial Hospital East enables on-site interventional cardiology including coronary angiography, balloon angioplasty, and stent placement. Direct ED access to the cath lab supports time-sensitive treatment of acute myocardial infarction, where door-to-balloon time is the primary determinant of outcomes. According to the American College of Cardiology, every 10-minute reduction in door-to-balloon time is associated with a measurable reduction in mortality for STEMI patients, making on-site cath lab capability in a community hospital a clinical asset of significant importance.
Healthgrades has recognized Memorial Hospital East for superior clinical outcomes in heart bypass surgery, coronary interventional procedures, heart attack treatment, heart failure treatment, and heart valve surgery. The hospital’s inclusion in America’s 250 Best Hospitals recognizes it as performing among the top 5% of hospitals in the nation for overall clinical excellence. The Patient Safety Excellence Award recognizes top-tier performance in preventing infections, medical errors, and other preventable complications.
Patients researching cardiac care options in the broader BJC HealthCare system may also review the profile of other Illinois and Missouri BJC hospitals, as the system connects patients in southwestern Illinois to Barnes-Jewish Hospital — one of the nation’s leading cardiac care centers — through its referral network.
Emergency Department and Pediatric Emergency Services
The Memorial Hospital East emergency department operates 24 hours a day and includes a specialized pediatric emergency unit staffed in collaboration with WashU Medicine physicians from St. Louis Children’s Hospital.
The adult emergency department provides around-the-clock care for the O’Fallon and Shiloh communities and surrounding southwestern Illinois areas. The pediatric emergency unit embedded within the ED brings subspecialty pediatric expertise from one of the nation’s top children’s hospitals directly into the community, eliminating the need for families to drive to St. Louis for pediatric emergency evaluation.
St. Louis Children’s Hospital, BJC HealthCare’s dedicated children’s hospital, holds Illinois Level 1 Pediatric Trauma Center designation — one of only a few outside the Chicago area in Illinois. The collaboration between Children’s physicians and Memorial Hospital East’s emergency team extends that expertise into southwestern Illinois without requiring patient transfers for appropriate initial evaluation and stabilization.
Family Care Birthing Center
The Family Care Birthing Center at Memorial Hospital East provides advanced maternal and neonatal care for pregnancies as early as 30 weeks, with 16 private LDRP suites, two dedicated C-section rooms, 24-hour neonatology coverage, a Level II E nursery, and an OB-GYN emergency department.
The LDRP design allows mothers to labor, deliver, recover, and receive postpartum care in a single private room rather than moving through multiple units. This model improves the patient experience and reduces care transitions during a clinically critical period. The in-house Level II E nursery and 24-hour neonatology coverage allow the center to care for premature infants as young as 30 gestational weeks, reducing the need to transfer medically complex newborns to tertiary facilities in most cases.
The dedicated OB-GYN emergency department within the birthing center allows expectant mothers with obstetric emergencies to be evaluated in a specialized environment rather than the general ED, improving triage efficiency and patient comfort for a vulnerable population. Prenatal classes and breastfeeding support extend the center’s services beyond the delivery itself, building a continuum of maternal wellness programming for the community. According to the American College of Obstetricians and Gynecologists, access to a co-located NICU and neonatology coverage in a community birthing center significantly reduces the need for maternal-fetal transport and improves outcomes for high-risk deliveries.

Siteman Cancer Center
The Siteman Cancer Center on the Memorial Shiloh campus provides patients in southwestern Illinois with access to NCI-designated Comprehensive Cancer Center care, including WashU Medicine oncologists and the full range of diagnostic and treatment services from one of the nation’s largest cancer programs.
Siteman Cancer Center is a partnership between BJC HealthCare and Washington University School of Medicine and holds designation as a Comprehensive Cancer Center by the National Cancer Institute — a distinction held by fewer than 60 centers nationwide. The NCI Comprehensive Cancer Center designation reflects demonstrated leadership in cancer treatment, research, prevention, and community outreach. Its presence on the Shiloh campus means southwestern Illinois patients have access to the same physician network, clinical trial portfolio, and treatment protocols as patients at the main Siteman locations in St. Louis.
Services at the Shiloh Siteman campus include medical oncology, chemotherapy and infusion therapy, and cancer-specific diagnostic services. Patients with complex or rare cancers can be seen by WashU Medicine subspecialty oncologists locally or referred seamlessly to the main Siteman campus when needed. The Harold and Dixie LePere Breast Health Center, located in the first Medical Office Building on campus, provides dedicated breast cancer screening, diagnosis, and treatment coordination alongside the Siteman program.
Magnet Designation and Nursing Excellence
Memorial Hospital East earned Magnet designation for nursing excellence from the American Nurses Credentialing Center in 2018, making it one of only two hospitals south of Springfield, Illinois to hold this distinction, along with Memorial Hospital Belleville.
Magnet designation is the highest recognition the ANCC confers on hospital nursing departments. It evaluates nursing leadership, practice environment, professional development, patient outcomes, and nursing research. Fewer than 10% of US hospitals hold Magnet status. Memorial Hospital East’s achievement is notable given the hospital opened in 2016 — earning the distinction within just two years of opening reflects a pre-built nursing culture and organizational infrastructure that prioritized excellence from the outset.
The hospital’s nursing excellence also connects to its broader care quality: Magnet-designated hospitals consistently outperform non-Magnet hospitals on patient outcome measures and are associated with lower rates of nurse-sensitive complications, according to research published in Medical Care and other peer-reviewed nursing outcomes journals.
BJC HealthCare System and WashU Medicine Integration
Memorial Hospital East operates within BJC HealthCare, one of the largest non-profit healthcare systems in the United States, and is physician-staffed in part through WashU Medicine — Washington University School of Medicine’s clinical practice organization, one of the nation’s top-ranked medical schools.
BJC HealthCare spans Missouri, southern Illinois, and, following a 2024 integration, eastern Kansas through the combined BJC and Saint Luke’s Health System. With 44,000 employees, the combined system is one of the largest employers in Missouri. For Memorial Hospital East patients, BJC membership means access to a care network that includes Barnes-Jewish Hospital, Barnes-Jewish West County Hospital, Missouri Baptist Medical Center, and other system hospitals, with referral pathways to subspecialists at facilities consistently ranked among the nation’s best.
WashU Medicine physicians staff the pediatric emergency unit, the Siteman Cancer Center on campus, and other specialty services at Memorial Hospital East. This integration brings academic medicine faculty-level expertise into a community hospital setting, a model that distinguishes the Shiloh campus from independently operated community hospitals in the region. Patients can schedule appointments and manage their care through MyChart, BJC’s patient portal, accessible at mypatientchart.org.
Patients exploring other Illinois and Midwest hospitals with similar BJC or major health system affiliations may find relevant context in the profile of Linden Oaks Hospital in Naperville, an Illinois behavioral health facility within a similarly large integrated health system, or the profile of Hurley Medical Center in Flint, Michigan for comparison with another full-service community hospital serving a midwestern population.
