Frequently Asked Questions

Common questions and expert answers about this procedure

What does high severity mean in the emergency department?

It describes problems that could be life-threatening or cause serious harm without rapid evaluation and treatment. Care is urgent and often involves multiple tests and close monitoring.

What happens during a high severity ED visit?

You will be triaged, monitored, and evaluated by clinicians. Tests like blood work, X-rays, CT scans, or ECGs may be ordered, and treatments or specialist consults may occur.

How long will I be in the ED?

Time varies with your condition, needed tests, and crowding. High severity evaluations often take several hours and sometimes lead to observation or hospital admission.

Will I be admitted to the hospital?

Some people go home after treatment; others are admitted for monitoring, procedures, or advanced care. The decision depends on test results and clinical assessment.

What tests might be done?

Common tests include blood work, ECG, X-rays, CT or ultrasound, and sometimes advanced imaging or procedures. Testing depends on your symptoms and exam.

Who will care for me in the ED?

A team may include emergency physicians, advanced practice clinicians, nurses, technicians, and specialists. They work together to evaluate and treat urgent conditions.

Why might there be a wait even if my symptoms are serious?

Triage assigns priority based on risk. If other patients have time-critical needs, you may wait while still being monitored and reevaluated.

How are costs handled for an ED visit?

Charges can include the facility fee, clinician services, tests, medicines, and imaging. Out-of-pocket costs vary by insurance benefits and network status.
