When someone walks through the doors of an emergency department, the moments that follow can feel disorienting — urgent voices, rapid movement, and a waiting area that offers no obvious signal about what happens next. For patients and their families, understanding what the hospital is doing and why can make that experience significantly less stressful. At HSHS St. Mary’s Hospital Medical Center in Green Bay, Wisconsin, the emergency department operates according to a structured, evidence-based process designed to ensure that every patient receives the level of care their condition demands, at precisely the moment they need it.
This article examines how the triage system works at St. Mary’s Hospital Medical Center, what patients can expect from arrival to treatment, and how the emergency team balances speed, accuracy, and compassion in one of the most demanding clinical environments in healthcare.
What Is Triage and Why Does It Matter?
The word “triage” originates from the French verb trier, meaning to sort or select. In the context of an emergency department, it is the process of rapidly evaluating each incoming patient and assigning a care priority based on the severity of their condition. It is not a gatekeeping mechanism — it is a clinical safeguard that ensures patients who face life-threatening danger are seen immediately, while those whose conditions allow for a brief wait do not consume resources needed elsewhere.
Triage has its roots in military medicine, developed to manage large numbers of casualties with limited resources. In modern U.S. hospital emergency departments, it has evolved into a highly refined, standardized process guided by nationally recognized frameworks, ensuring that medical logic — not arrival order — determines who gets seen first.
Inside the Emergency Department at HSHS St. Mary’s Hospital Medical Center
Founded in 1903, HSHS St. Mary’s Hospital Medical Center is a 158-bed not-for-profit community hospital situated on Green Bay’s west side at 1726 Shawano Avenue. As part of the Hospital Sisters Health System, it serves patients across Northeast Wisconsin and Michigan’s Upper Peninsula, functioning as a central pillar of emergency care for a broad and diverse regional population.
The emergency department at St. Mary’s Hospital Medical Center is open around the clock and features 25 dedicated patient rooms staffed by full-time physicians and nurses who specialize in emergency medicine. With board-certified emergency physicians on duty at all times and specialists available on-call, the department handles everything from minor lacerations and broken bones to cardiac events, strokes, and serious trauma. HSHS St. Mary’s Hospital Medical Center highlights rapid assessment and stabilization of critically injured patients as a core operational priority, supported by leading-edge diagnostic technology for fast, accurate decision-making.
The Emergency Care Team
The effectiveness of the triage process depends heavily on the people behind it. At St. Mary’s Hospital Medical Center, the emergency team is multidisciplinary, with each member contributing specialized skills to a seamless care continuum. The table below outlines the principal roles within the emergency department:
| Role | Primary Responsibilities |
|---|---|
| Emergency Physicians | Board-certified doctors who lead patient evaluation, diagnosis, and treatment decisions |
| Emergency Nurses | Specially trained in emergency care; conduct triage assessments and manage ongoing patient needs |
| Surgeons and Specialists | Available on-call for procedures requiring specialized expertise or emergency surgery |
| Radiology and Lab Technicians | Process imaging (X-rays, CT scans) and laboratory tests rapidly to support fast, accurate diagnoses |
| Respiratory Therapists | Manage breathing-related emergencies including asthma, pneumonia, and trauma-related respiratory issues |
| Social Workers and Case Managers | Coordinate follow-up care, connect patients with community resources, and assist with discharge planning |
Together, these professionals function as an integrated clinical unit, moving patients efficiently through each phase of the emergency care pathway while maintaining a consistently high standard of both medical and human care.
The Triage Classification System
Emergency departments across the United States widely use the Emergency Severity Index (ESI) — a validated, five-level framework that stratifies incoming patients by clinical urgency and anticipated resource requirements. The ESI allows triage nurses to make rapid, reproducible decisions that direct each patient toward the appropriate level of care.
Understanding this scale helps patients and families interpret why some individuals are seen before others, even those who arrived later. The table below describes each ESI level:
| ESI Level | Classification | Clinical Description | Common Examples |
|---|---|---|---|
| Level 1 | Resuscitation | Requires immediate life-saving intervention; no waiting | Cardiac arrest, unresponsiveness, severe respiratory failure |
| Level 2 | Emergency | High-risk condition; must be seen within 10 minutes | Chest pain, altered mental status, stroke symptoms, major trauma |
| Level 3 | Urgent | Requires two or more clinical resources; stable but needs timely attention | Abdominal pain needing imaging and labs, moderate fractures |
| Level 4 | Semi-Urgent | Requires one clinical resource; condition is stable | Minor lacerations, urinary tract infections, simple fractures |
| Level 5 | Non-Urgent | No additional diagnostic resources needed; condition is stable | Minor rashes, sore throat, minor sprains |
This classification ensures that resources are allocated with medical logic at the forefront. An ESI Level 1 patient is taken directly to a treatment room, bypassing registration entirely, while a Level 5 patient may wait longer knowing their condition poses no immediate threat.
The Patient Journey: From Arrival to Treatment
The path a patient takes through the emergency department at HSHS St. Mary’s Hospital Medical Center follows a carefully designed sequence that balances clinical urgency with operational efficiency. Here is a stage-by-stage breakdown of what patients can typically expect:
Stage 1: Arrival and Initial Contact
Patients arriving at St. Mary’s Hospital Medical Center enter through the main entrance on Shawano Avenue, where emergency staff acknowledge them immediately. Those arriving by ambulance benefit from dedicated transfer protocols ensuring a smooth handoff from paramedics to the emergency team, while those arriving by personal vehicle are directed to the triage area.
One of the first actions is a rapid visual assessment — sometimes called an “across-the-room” evaluation — conducted by a nurse or emergency technician. If a patient presents with obvious indicators of a life-threatening emergency, such as loss of consciousness or severe respiratory distress, they are moved directly into a treatment room without waiting for a formal triage assessment.
Stage 2: Triage Assessment
For patients who do not require immediate intervention, a trained triage nurse conducts a brief but comprehensive evaluation. This process typically takes between two and five minutes and includes a standard set of clinical assessments. The following elements are typically evaluated during triage:
- A short medical history and description of the patient’s current symptoms
- Measurement of vital signs, including blood pressure, heart rate, respiratory rate, temperature, and oxygen saturation
- Pain assessment using a standardized numeric or visual scale
- Identification of any high-risk conditions, including “danger zone” vital signs that indicate serious instability
- Assignment of an ESI triage level based on clinical findings and expected resource needs
In many cases, the triage nurse may also initiate early diagnostics — drawing blood or ordering an electrocardiogram — before the patient reaches a treatment room. This front-loading strategy reduces total wait time by having critical results ready when the physician begins their evaluation.
Stage 3: Registration and Documentation
Following triage, patients who are stable enough to wait for an available treatment room proceed through the registration process. Patient Access Specialists collect demographic and insurance information and obtain the patient’s consent for treatment. This step enables the care team to create or update a patient medical record and allows the physician to issue orders for diagnostic tests with the appropriate documentation in place.
For patients taken directly to a treatment room because of their condition’s severity, registration staff conduct bedside registration — bringing the administrative process to the patient rather than the reverse. At HSHS St. Mary’s Hospital Medical Center, the Epic electronic health record system supports the care team by maintaining a comprehensive, real-time record of each patient’s status and orders throughout their visit.
Stage 4: Physician Evaluation and Diagnostics
Once a patient is placed in one of the 25 treatment rooms, an emergency physician or advanced practice provider conducts a thorough clinical evaluation — taking a detailed history, performing a physical examination, and ordering any diagnostic tests needed. The department’s in-house capabilities are central to the speed of this process. Among the tools available are:
- X-rays for suspected fractures, lung conditions, and other structural assessments
- CT scans for detailed evaluation of the brain, chest, abdomen, and spine
- Electrocardiograms (ECGs) for cardiac rhythm and function assessment
- Laboratory blood and urine tests across a broad panel of diagnostic markers
Having these capabilities within the department itself is a meaningful operational advantage. Results become available quickly, enabling the physician to act without unnecessary delays in the diagnostic chain.
Stage 5: Treatment, Discharge, or Admission
Once the physician has a complete clinical picture, treatment begins. Depending on the diagnosis, this may involve medication administration, wound closure, fracture management, procedural intervention, or intensive monitoring. Emergency nurses manage medications — including intravenous fluids — and track the patient’s response in real time. When treatment concludes, one of two paths follows: discharge or inpatient admission.
Patients who no longer require inpatient care are discharged with written instructions covering self-care, prescribed medications, follow-up appointments, and warning signs that should prompt a return to the emergency department. Those requiring continued inpatient care are transferred to an appropriate unit. For cases involving highly specialized trauma or surgical needs, coordinated transfer protocols connect St. Mary’s Hospital Medical Center with the Level II Trauma Center at HSHS St. Vincent Hospital in Green Bay, ensuring seamless access to advanced care within the regional system.
Conditions Treated in the Emergency Department
The scope of conditions managed at St. Mary’s Hospital Medical Center’s emergency department reflects the breadth of the clinical team’s training and the depth of available diagnostic technology. Among the most common presentations are:
- Stroke and other neurological emergencies
- Heart attack and acute cardiac events
- Shortness of breath, including asthma and pneumonia
- Motor vehicle accidents and traumatic injuries
- Broken bones and joint dislocations
- Lacerations and acute wound care

- Mental health crises requiring immediate stabilization
- Dehydration, sepsis, and serious infections requiring IV therapy
This comprehensive range of capabilities positions HSHS St. Mary’s Hospital Medical Center as a primary emergency resource for a large and geographically diverse population across Northeast Wisconsin and Michigan’s Upper Peninsula.
Specialized Response: Stroke Care Within the Emergency Department
A defining feature of the emergency care model at St. Mary’s Hospital Medical Center is its status as a nationally certified Primary Stroke Center, a designation certified by The Joint Commission and held for over a decade. Stroke is a condition where every minute of delayed treatment corresponds to measurable neurological damage — making seamless integration between triage and stroke-specific protocols essential.
When a patient presents with stroke symptoms — sudden facial drooping, arm weakness, or difficulty speaking — the triage nurse immediately escalates the ESI classification and activates the stroke response protocol. This involves rapid imaging, neurological assessment, and time-sensitive interventions such as clot-dissolving medication where appropriate. For patients requiring advanced intervention, transfer protocols link HSHS St. Mary’s Hospital Medical Center directly to the Comprehensive Stroke Center at HSHS St. Vincent Hospital.
HSHS St. Mary’s Hospital Medical Center also maintains telestroke capabilities — allowing the stroke team to access real-time neurological expertise remotely when needed, further strengthening the accuracy of time-sensitive decisions made within the emergency department.
What Patients and Families Should Know Before Visiting
Understanding a few practical points before arriving can reduce anxiety and help patients navigate their visit more effectively. The following reflect how the emergency department at St. Mary’s Hospital Medical Center operates in practice:
- Priority is determined by medical severity, not arrival order. A patient with a minor complaint may wait longer than someone who arrives after them but has a higher ESI classification.
- Triage assessments are dynamic. If a patient’s condition worsens while waiting, they should notify a triage nurse immediately — re-evaluation and re-classification can occur at any time.
- The emergency department entrance is on Shawano Avenue, at the circular drive outside the main lobby atrium, with parking available in the adjacent lot.
- For life-threatening emergencies, calling 911 is always the safest choice — paramedics can initiate critical care before arrival and communicate directly with the emergency team.
These straightforward details can make a meaningful difference during what is often one of the most stressful moments in a person’s life.
