Mercy Emergency Department - Mercy Hospital St. Louis

The Mercy Hospital St. Louis Emergency Department is the only Level I (highest level) Trauma Center in St. Louis County. Mercy's Emergency Department handles a major share of the area's trauma cases and provides medical direction for six fire/ambulance districts. Our Emergency Department staff diagnoses and treats major and minor traumatic and medical emergencies, providing advanced care 24 hours- a-day, every day.

The Emergency Department features:

• An Adult Emergency Department, with its own triage and waiting room, 24 adult treatment rooms and six adult trauma rooms
• A separate Pediatric Emergency Department, its own triage and waiting room, eight pediatric treatment rooms and four pediatric trauma rooms
• A six-room area designated for minor injuries and illnesses
• State-of-the-art treatment areas and centrally-located imaging services
• A large ambulance bay with capacity for five ambulances
• A large helipad with space for several helicopters

The most recent addition to the  Mercy Emergency Department is the Clinical Decision Unit. This new 16-bed unit offers 24-hour care for patients as they are awaiting a clinical decision about whether they should be admitted to the hospital or be released to their homes. Often, clinical staff are waiting for test results before a final decision is made about admitting a patient to the hospital. The patients stay in this area for a short time - usually under 24 hours. The new unit is directly above the Emergency Department, on the second floor of the Heart Hospital. The staff caring for the CDU patients are the same level emergency physicians, nurse practitioners and nurses who care for patients in the ED.
