Knowing whether to choose the emergency room vs. urgent care can help you get the right level of medical care without unnecessary delays or added costs. In general, it’s recommended to go to the ER for life-threatening symptoms or injuries, while urgent care is recommended for illnesses and injuries that need prompt attention but are not medical emergencies. Read on to learn more about the differences between the emergency room and urgent care and find out how to decide whether the ER or urgent care is the right choice for some of the most common symptoms and injuries.
Understanding the Difference Between Urgent Care and the ER
Choosing between the ER vs. urgent care starts with understanding what each facility is intended for. An urgent care clinic treats illnesses and injuries that require same-day medical attention but are not life-threatening. These injuries or illnesses are too important to wait for a primary care appointment but typically don’t require the advanced resources available in a hospital emergency department.
An ER is equipped to diagnose and treat serious or life-threatening medical emergencies. Emergency departments have access to advanced imaging equipment, emergency surgery facilities, intensive care units and medical specialists who are available around the clock.
If you’re wondering when to go to the ER vs. urgent care, the severity of your symptoms is usually the most distinguishing factor. If your symptoms are severe and potentially life-threatening, such as excessive bleeding or difficulty breathing, the ER is the safest choice. For less severe illnesses and injuries that still warrant prompt medical attention, urgent care can often provide timely and comprehensive treatment without the added costs associated with an ER visit.
What Can Urgent Care Not Treat?
Urgent care clinics offer a wide range of medical services, but they are not equipped to manage conditions that require advanced hospital-level care or immediate life-saving treatment. Examples of conditions urgent care cannot treat include:
- Heart attacks
- Strokes
- Loss of consciousness
- Severe difficulty breathing
- Major trauma
- Severe head injuries
- Uncontrolled bleeding
- Severe allergic reactions that cause swelling of the airways
- Injuries or illnesses that require emergency surgery
If you or a loved one are experiencing any of these severe symptoms, call 911 or go to the nearest ER immediately.
ER vs. Urgent Care: Symptom-by-Symptom Guide
Chest pain
Chest pain can have many causes, including muscle strain, heartburn and anxiety. However, chest pain can also be a significant warning sign of a heart attack or another serious heart condition.
Go to urgent care for:
- Mild chest pain that seems related to a muscle strain
- Chest pain that occurs after minor injury
Go to the ER immediately if chest pain:
- Is severe or sudden
- Feels like pressure, squeezing or tightness
- Spreads to the neck, jaw, shoulder or arm
- Occurs with shortness of breath, dizziness, excessive sweating or nausea
When in doubt, chest pain should always be evaluated as soon as possible. If you think you may be having a heart attack, call 911 immediately.
Fever
Go to urgent care if a fever:
- Lasts longer than 48 to 72 hours
- Ranges from 100.5°F to 103°F
- Is accompanied by symptoms such as headache, rash, fatigue, nausea or vomiting
Go to the ER if fever occurs with:
- Mental confusion
- Difficulty breathing
- Severe dehydration
- Seizures
- Loss of consciousness
Cuts and wounds
Urgent care can often treat minor cuts requiring stitches:
- Minor cuts requiring stitches
- Small puncture wounds
- Minor burns
Go to the ER for:
- Severe bleeding that won’t stop
- Deep wounds exposing bone or muscle
- Serious burns
- Injuries involving significant trauma, especially to the head or neck
Sprains and broken bones
Urgent care can evaluate sprains:
- Sprains
- Strains
- Minor fractures
Go to the ER if you experience:
- A bone protruding through the skin
- Severe deformity of a limb or joint
- Loss of circulation
- Loss of consciousness
Difficulty breathing
Urgent care can evaluate breathing issues that stem from mild asthma flare-ups:
- Mild asthma flare-ups
- Upper respiratory illnesses
- Sinus infections
- Mild bronchitis symptoms
Go to the ER immediately if you experience:
- Severe shortness of breath
- Difficulty speaking because of breathing problems
- Blue lips or fingertips
Abdominal pain
Urgent care may be appropriate for:
- Mild stomach pain
- Nausea and vomiting without severe dehydration
- Mild diarrhea
- Suspected urinary tract infections
Go to the ER for:
- Severe or worsening abdominal pain
- Vomiting blood or bloody stools
- Severe abdominal swelling
- Fainting caused by significant abdominal pain
Symptoms can sometimes change quickly. If a health issue that initially seems mild becomes more severe, or if new symptoms such as difficulty breathing, mental confusion or severe pain develop, seek emergency medical care right away. Remember to trust your instincts, especially if you feel that something is seriously wrong.
