Emergency rooms, also known as accident and emergency departments (A&E), emergency wards (EW), or casualty departments, are hospital departments that provide specialized emergency care for patients with acute illnesses or injuries. They operate 24 hours a day, seven days a week, and are equipped to handle life-threatening situations that require immediate attention, such as heart attacks, strokes, and traumatic injuries. Due to the unplanned nature of patient attendance, emergency rooms use a priority system based on the severity of a patient's condition, with the most critically ill or injured patients receiving care first. This article will explore what constitutes an emergency in an emergency room, helping individuals make informed decisions about when to seek emergency care.

What You'll Learn
Life-threatening situations
Emergency rooms are equipped and staffed to provide life-saving services and other emergency care. They operate 24 hours a day, seven days a week, and are optimized for quick, short-term care. They use a priority system, where the most seriously ill or injured patients are cared for first. If you go with a minor problem, expect to wait for your turn.
Upon arrival, a triage nurse will assess your condition and place you in a priority queue based on the severity of your symptoms. This order may change as new patients with more severe symptoms arrive. The triage nurse will measure your pulse, blood pressure, temperature, respiratory rate, capillary refill time, ability to follow commands, and other vital signs.
If you are severely ill, you will be sent for admission to the hospital. If you don't need admission, you will be sent home after the initial treatment to complete treatment with your own doctor. A doctor specializing in emergency medicine will examine you and begin your treatment. They may order tests like X-rays, electrocardiograms (EKG), and others, depending on your health problem. The doctor will then discuss your problem and results with you and advise admission to the hospital, if necessary.

Illnesses and injuries
Examples of life-threatening conditions that require emergency care include heart attacks, strokes, severe bleeding, major trauma, respiratory distress, and severe allergic reactions. In the case of injuries, a sudden injury due to a motor vehicle accident, burns, smoke inhalation, near drowning, deep or large wounds, or other severe trauma may require emergency medical attention.
It is important to note that not all illnesses and injuries qualify as medical emergencies. Urgent care facilities provide immediate treatment for minor, non-life-threatening illnesses and injuries. These include common conditions such as colds, flu, earaches, sore throats, migraines, minor fractures, sprains, minor cuts, minor burns, and minor eye injuries. Urgent care clinics help fill the gap when your regular doctor is not available, and you cannot wait for an appointment.
When faced with an illness or injury, it is essential to assess the severity and determine whether it requires emergency or urgent care. This decision can be challenging, and it is always better to seek medical attention sooner rather than later. Knowing the differences between emergency and urgent care can help ensure that you receive timely and appropriate treatment.

Psychiatric problems
Psychiatric emergencies are acute disturbances in thought, behaviour, mood, or social relationships that demand immediate intervention. These emergencies can arise from a variety of conditions, including attempted suicide, substance abuse, alcohol intoxication, acute depression, psychosis, and rapid changes in behaviour. Psychiatric emergency services are provided by professionals in medicine, nursing, psychology, and social work.
The psychiatric emergency evaluation process involves an initial triage to assess the severity and dangerousness of the situation, focusing on the temporal development of symptoms, associated signs and symptoms, and possible causes. This is followed by diagnostic assessment, management of acute symptoms, and disposition to the appropriate level of care. The goal is to provide immediate treatment and crisis stabilization, ensuring the safety of patients, colleagues, and third parties.
The environment and context of emergency psychiatry pose challenges in maintaining confidentiality, especially when there is a threat of violence. In such cases, under the Tarasoff doctrine, clinicians have an obligation to warn individuals who may be at risk. The management of psychiatric emergencies may involve reassurance, referral to other resources, medication, or hospitalization. Brief psychotherapy can be effective in emergency settings if the patient understands their issues, trusts the physician, and is motivated to change.
The prevalence of psychiatric emergencies in non-psychiatric institutions, such as general hospitals, is estimated to range from 10% to 60%. The initial care of psychiatric emergencies often takes place in these general hospital settings due to their accessibility and stigma-free nature. The demand for emergency psychiatric services has been increasing, especially among US children, adolescents, and young adults, highlighting the challenges and progress in behavioural healthcare.

Non-emergency cases
It is important to understand the difference between an emergency and a non-emergency situation to ensure that hospital emergency rooms are reserved for critical cases. While emergency rooms provide medical care at any time, day or night, and are equipped to handle complex and critical needs, non-emergency cases can be treated at urgent care centres or walk-in clinics. These centres often have X-ray, lab, and other diagnostic services, and can handle more severe non-emergencies.
If you are unsure whether your situation is an emergency, it is recommended to call your primary care doctor or a nurse hotline to seek advice. Additionally, if you feel your life is at risk, call emergency services or visit the emergency room. It is always better to be safe than sorry, and emergency rooms are designed to provide prompt and specialized care for severe and critical cases.
It is important to note that seniors visit emergency departments at higher rates than non-seniors, sometimes for non-emergency conditions or accidents. This highlights the need to understand the difference between emergency and non-emergency care to ensure efficient utilization of emergency resources.

Emergency room design
The design of an emergency room (ER) is critical to ensuring that patients receive prompt and effective treatment. ERs are hospital departments that specialize in providing emergency medicine and acute care for patients with dangerous health conditions, ranging from mild illnesses to life-threatening injuries. The unplanned nature of patient attendance means that ERs must be equipped and designed to handle a broad spectrum of illnesses and injuries. Here are some key considerations for ER design:
Triage Area:
A dedicated triage area is essential for assessing and prioritizing patient needs. Upon arrival, a triage nurse evaluates each patient's condition and places them in a priority queue based on the severity of their symptoms. This dynamic queue allows for the flexible management of patient flow, as new patients with more severe symptoms may arrive at any time.
Diagnostic Equipment:
To optimize treatment speed, ERs typically have their own diagnostic equipment, including radiographic examination rooms with CT scanners and ultrasonography equipment. This setup avoids delays caused by relying on shared equipment in other hospital departments. Additionally, ERs may have their own "STAT Labs" for rapid basic laboratory services, such as blood counts, blood typing, and toxicology screens.
Specialized Treatment Rooms:
ERs should include specialized treatment rooms to cater to specific medical emergencies. These may include resuscitation rooms, eye, ear, nose, and throat examination rooms, orthopedic injury rooms, obstetrical emergency rooms, and cardiac emergency rooms. This design allows for the efficient management of diverse patient needs.
Mental Health Facilities:
Psychiatric emergencies are a significant aspect of ER care. Many hospitals have separate areas for evaluating psychiatric problems, often staffed by psychiatrists, mental health nurses, and social workers. These areas may include rooms specifically designed for individuals who pose a risk to themselves or others, such as those experiencing suicidal ideation.
Patient Flow and Capacity:
ER design should consider patient flow and capacity management. The use of a priority system based on illness severity means that efficient patient flow patterns and waiting areas are crucial. Metrics such as arrivals per hour, percentage of ER beds occupied, and patient age help determine staffing requirements and bed capacity.
Signage and Wayfinding:
Clear and prominent signage is essential in ERs to ensure that patients and their companions can easily navigate to the department. The use of white text on a red background has become a widely recognized standard for indicating the location of emergency departments globally.
Overall, the design of an ER should facilitate rapid patient assessment, efficient treatment, and flexible prioritization based on symptom severity. By incorporating these design considerations, ERs can optimize their ability to provide life-saving care and manage the diverse range of medical emergencies they encounter.

Frequently asked questions
An emergency room, also known as an emergency department, accident and emergency department, or casualty department, is a medical treatment facility specializing in emergency medicine and the acute care of patients who arrive without prior appointments. They are equipped and staffed to provide life-saving services and other emergency care.
You should go to an emergency room if you are experiencing a medical emergency that requires immediate attention. This includes situations where waiting for treatment would be dangerous, such as severe chest pain, severe bleeding, feeling faint, impaired vision, heart attack, stroke, or drug overdose.
Upon arrival, a triage nurse will assess your condition by checking your vital signs, including pulse, blood pressure, temperature, respiratory rate, and capillary refill time. The most seriously ill or injured patients will be treated first, so those with minor problems may experience longer wait times.
If your condition is not life-threatening but you are still concerned, you can consider visiting an urgent care clinic or a walk-in clinic. These facilities can treat minor illnesses and injuries, such as colds, flu, sprains, minor cuts, and rashes. They offer faster and more convenient access to medical care than emergency rooms.
